1. Stacking: The drugs to be sterilized are wrapped and then placed sequentially on the sieve plate inside the sterilization bucket with proper clearance between the bag and the package to facilitate the cold air in the sterilization bucket to overflow and steam penetration, improve sterilization.
2. Add water: add 4 liters of clean water in the portable sterilizer body, the water will gradually evaporate in the process of extinguishing, the water level will be reduced accordingly. Therefore, before each sterilization, make up the amount of water inside the sterilizer main body, so as not to dehydration dry electric heater, electric heater damage.
3. Sealing: Put the drum into the pressure steam sterilizer main body, insert the hose on the cover into the semi-circular groove on the inner wall of the sterilizer and close the cover. Aligning the bolt groove on the cover with the bolt groove of the main body, and then sequentially aligning the wing nut in the opposite orientation to the groove to tighten the cover evenly with the main body.
4. Heating: the sterilizer power plug into the 10A / 220V power outlet. Turn the power switch to "on" position, power indicator light, heating tube began to heat. And then the deflation valve plate hand dial to the "deflated" position to be more urgent when the steam is discharged, the deflation valve plate is about to dial to "off" position. At this point pressure gauge pointer clockwise slow rotation, indicating that the pressure inside the sterilizer is gradually rising, while the temperature increases.
5. Sterilization: When the pressure within the sterilizer reaches the desired range, the user can start to calculate the sterilization time, according to different items and packaging, with reference to (Table I) to determine the time required for sterilization. In the sterilization process, the user can sterilize the power switch "on" or "off" to properly adjust the heat source, or connected to a regulator transformer, the appropriate lower voltage so that the pressure inside the sterilizer in the regulator status. However, the pressure inside the sterilizer can not be kept below the user selected value. If the user does not use the above-mentioned method of controlling the heat source, the safety valve will intermittently release the over pressure steam during the sterilization process, and the setting pressure inside the sterilizer is 0.165 MPa at this time.
6. Drying: For medical devices, dressings, utensils and other items that need to be dried quickly after sterilization, the sterilizing steam can be quickly discharged through the bleed valve at the end of sterilization until the pressure gauge hands return to " 0 "scale, and then wait a minute or two after the cover open. Open the cover, and then continue to heat 10 to 15 minutes, so that items on the residual water vapor evaporated. Then turn the power switch to "off" position, stop heating.
7. Cooling: Sterilization of liquid such as medium, etc. After the sterilization is complete, the vaporizer must not be quickly discharged through the vent valve, so as to avoid violent boiling liquid overflow or bottle rupture and other dangerous accidents. Therefore, after sterilizing the sterilized articles of this type, the power switch should be turned to the "OFF" position first, and the heating should be stopped until it is cooled down until the pressure gauge hands return to the "0" scale, and wait a few minutes before releasing Hand valve plate to the "release steam" position. Then you can open the cover.

Most people don’t take bilge pumps seriously unless they’ve had a boat flooded or sunk already. That’s a mistake. Sinking at the dock is one thing, but sinking 20 miles offshore is bad news. All it takes is one faulty exhaust hose to fill a hull full of water. The size of your bilge pump needs to work with the size of your boat. Any boat that is over 16 feet in length will want to invest into two pumps instead of just one.

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. a varying current in one coil of the transformer produces a varying magnetic field.
High frequency transformers and low frequency transformers for Industry use are widely used in the following industry, such as Cosmetic machinery system, instrument system:

In recent years, scooters has rapid developed in Europe, Asia.
Nimrod Sapir from Israel has developed the inokim series of scooters, an innovative urban transportation solution,

We know that the disinfection of materials often due to one or more of the following reasons: the material flow, easy handling, easy to save and storage, reduce shipping costs, access to the desired product quality. In the production process, due to equipment quality, supporting components and basic research and other aspects still need to be further improved, the current routine disinfection and sterilization is still the main form of disinfection and sterilization.
As each has its own sterilization and sterilization advantages and scope of application, so combined disinfection and sterilization will be the future trend of development. Next, Xiao Bian first and everyone together to understand and discuss under the conventional disinfection and sterilization equipment:

Oven using horizontal laminar flow that side of the side of the back to the wind, the role of the fan, the top of the hot air from the side of the high temperature and high efficiency filter into the box. In the efficient filter outlet equipped with air baffle, so that the box air flow evenly. HD-MJX rubber stopper sterilization oven Oven top with the inlet and outlet, and the inlet with a cooling fan, under the strong fan, the 10,000 air through the high efficiency filter into the box, so that items Achieve rapid forced cooling, outlet equipped with high efficiency filters and throttle, exhaust valve can be wet or manual control of PLC programmable controller. Stainless steel mixing drum from a will be placed in which the cleaning materials, start the transmission mechanism, the material in which the natural flip drying, and set a tray, a discharge convenient. Open the oven door interlock device, when one side door open, the other side of the door can not be opened, and the indicator shows the situation open the door can be set to open the door at the specified temperature. Rubber stopper manufacturers and pharmaceutical manufacturers preferred sterilization equipment
On the door sterilization oven: suitable for pharmaceutical, chemical, food, aquaculture industry materials sterilization, insulation, curing, baking, testing and other heat treatment. Commonly used in pharmaceutical manufacturers Vials, ampoules, rubber stopper, aluminum cover, metal and glassware disinfection and sterilization. Open the door for sterilization before and after the oven door way to facilitate the access of materials and conversion of different purification level of the workshop.
In fact, no matter the type of disinfection and sterilization equipment, its development should also pay attention to the comprehensive utilization of energy conservation and energy, such as the use of a variety of joint heating, transplanted heat pumps and heat pipe technology, the development of solar energy disinfection and sterilization machines; In addition, as human beings attach importance to environmental protection, improve the environmental protection measures of disinfection and sterilization machine to reduce the leakage of dust and exhaust gas, etc., will also be in need of further Direction of the research.
 

Sterilization by means of a suitable physical or chemical means to kill microorganisms living in the article or method to remove. This law applies to sterile preparation, raw materials, accessories and medical equipment and other items. Sterile refers to goods does not contain any living micro-organisms. However, for any number of steam bottle sterilizer products, both can not guarantee absolute sterility test can not be used to confirm. Physical or chemical means sterilization tests showed: kill microorganisms on the number of rules to follow, therefore, sterile sterilized items after items sterilization standards generally microbial survival probability – sterility assurance level SAL (Sterility Assurance Level) said. Probability of surviving microorganisms terminally sterilized product shall not exceed 10-6. Sterilized products meet the sterility assurance level can be determined by verification. Sterilization and sterility assurance products can not rely on sterility testing of the final product, but on the process used in the production of qualified sterilization process, strict management and good GMP comprehensive quality assurance system. Sterilization process should be determined by considering the nature of the items to be sterilized, effective and economic method of sterilization, the sterilization integrity and stability of the article and other factors.
Validate the sterilization process is a necessary condition of sterility assurance. Sterilization process validated only after the delivery of official use. Verify that include:
⑴ written verification program and the development of assessment criteria.
⑵ confirm sterilization equipment technical information is complete, correct installation , and can be in normal operation ( Installation Qualification ).
⑶ confirm critical control equipment and instrumentation to the normal operation ( OQ ) within the parameters specified.
⑷ using sterilized items or items repeated simulation tests to confirm compliance with the sterilizing effect ( Performance Qualification ) .
⑸ Summary and improve a variety of documents and records, written verification reports. Daily production in response to the operation of sterilization procedures to monitor, identify key parameters ( such as temperature, pressure, time, humidity, gas concentration and irradiation sterilization absorbed dose absorption, etc. ) are within the range defined in the verification.
Sterilization procedures should be periodically re-verified. When changes (including sterilization load and number of items changes ) occur when sterilization procedures, should be re- verified. Characteristics of the product prior to sterilization and sterility assurance products is the extent of contamination and pollution associated bacteria. Therefore, strict monitoring of microbial contamination levels before sterilization and sterilization product contamination tolerance of bacteria, and to take all measures in all aspects of production to reduce pollution and ensure control of microbial contamination within the specified limits. After sterilization, the sterilized items should prevent recontamination . Under no circumstances, should be required to ensure that the product container and sealing system in the period in line with sterile requirements.
Sterilization methods have used methods of sterilization heat sterilization, dry heat sterilization, gas sterilization, radiation sterilization and sterile filtration method. The method may be employed in combination with one or more items to be sterilized in the sterilization according to the characteristics. As long as the product allows, should be chosen as the final sterilization method ( ie, product packaging to packaging containers after sterilization ) sterilization. If the product is not suitable for terminal sterilization method, the choice of filter sterilization method or sterile production process sterility assurance requirements, whenever possible, to deal with non- terminally sterilized products as complementary sterilization ( such as circulating steam sterilization ).
First, heat sterilization
Items will be placed in this Act shall mean the use of high-pressure saturated steam sterilization cabinet, hot water spray and other means to make the microbial cell protein, nucleic acid denaturation and kill microorganisms. The Act sterilization capability for heat sterilization is the most effective and most widely used method of sterilization. Medicines, container, medium, sterile clothing, and other items stopper when the temperature and humidity do not change or damage are available sterilization law . Live steam can not completely kill bacterial spores, and can be used as an auxiliary heat-sterilized instruments sterile products.
Moist heat sterilization conditions usually 121 ℃ × 20min or 116 ℃ × 40min procedure can also be used with other temperature and time parameters. In short, we must ensure that SAL items after sterilization ≤ 10-6. The thermal stability of the article, can be over- kill method, the SAL should be ≤ 10-12. Standard sterilizing tattoo equipment of heat-sensitive products F0 time may be less than 8min, but it should be in the whole production process, the product of strict monitoring of microbial contamination, and to take all measures to prevent pollution and reduce microbial resistant bacteria pollution levels, ensure that sterilized product sterility assurance requirements.
When using moist heat sterilization, should be sterilized items are packed and loaded the appropriate way to ensure the effectiveness and uniformity of sterilization.
When moist heat sterilization process validation, testing should be conducted heat distribution, heat penetration testing and validation testing of biological indicators. To determine the distribution of heat sterilizer load and load when the different chambers and the possible existence of cold spots; under no-load conditions, the temperature difference is recognized when the chamber 121 ℃ points should be ≤ ± 1 ℃; Use temperature probe inserted into the actual items or items within the simulation confirmed sterilizer at different loading, the coldest point of the article standard sterilization time (F0) to reach the set standards; further confirmed when the cold spots at different loading biological indicator sterilized items at a sterility assurance level. Law is commonly used biological indicators Bacillus stearothermophilus spores (Spores of Bacillus stearothermophilus).
Second, the dry heat sterilization
Law refers to items in the dry heat sterilizer, sterilization tunnel and other equipment, the use of dry and hot air to kill the microbes or eliminate pyrogen approach. But not suitable for high-temperature sterilization with moist heat sterilization sterilization items, such as glassware, metal containers, fiber products , solid reagents, liquid paraffin etc Act can be sterilized.
Dry heat sterilization conditions is generally 160 ~ 170 ℃ × 120min above , 170 ~ 180 ℃ × 60min or more, or 250 ℃ × 45min or more , may also have other temperature and time parameters. In short, should ensure that their products after sterilization SAL ≤ 10-6. After the dry heat over the killing of products SAL should ≤ 10-12, this time items generally determined prior to sterilization without microbial contamination. 250 ℃ 45min dry heat sterilization can also be removed by aseptic packaging containers and related equipment in the production of filling pyrogenic substances.
When using dry heat sterilization, should be sterilized items are packed and loaded the appropriate way to ensure the effectiveness and uniformity of sterilization.
Dry heat sterilization and moist heat sterilization validation same test should be carried out heat distribution, heat penetration test, validate biological indicator inactivation of bacterial endotoxin test or validation tests. To confirm the sterilizer temperature distribution in compliance with the standards set, to determine the coldest point, confirm the coldest point standard sterilization time (FH) can reach the set standards and achieve SAL requirements. Commonly used as a biological indicator Bacillus subtilis spores (Spores of Bacillus subtilis). Inactivation of bacterial endotoxin test in addition to verification test is to prove the effectiveness of pyrogenic process. Will generally not be less than 1,000 units of the bacterial toxin to be added to the items of pyrogen, the pyrogen- proof inner process can go down at least three pairs of endotoxin unit. Bacterial endotoxin test to verify inactivation of bacterial endotoxin used generally within Escherichia coli endotoxin (Escherichia coli endoxin). When validated, the general maximum loading mode.
Third, the radiation sterilization
Law refers to the electron beam sterilization product in the γ-ray radiation sources suitable or desirable for the occurrence of electron accelerators ionizing radiation to kill the microorganisms. Law is the most commonly used 60Co-γ ray radiation sterilization. Medical equipment, containers, production aids, from radiation damage of pharmaceutical raw materials and finished products etc. Sterilization Act is available.
Radiation sterilization sterilization method using sterile product which SAL should ≤ 10-6. γ -ray radiation sterilization is mainly controlled by the parameters of the radiation dose ( absorbed dose refers sterilized items ). The dose should be considered sterile goods develop adaptability and the maximum number of possible microbial contamination and the strongest anti- radiation, the dose should be used in advance to verify its effectiveness and safety. The absorbed dose of radiation sterilization used as 25kGy. The final product, bulk drugs, certain medical equipment sterilization should be used whenever possible low radiation dose. Before sterilization, items to be sterilized response quantity of microbial contamination and radiation intensity was measured to evaluate the sterilization process of the sterilized items given sterility assurance level.
When sterilization should be appropriate chemical or physical methods for sterilizing articles absorbed radiation dose monitor the extent to fully confirm the sterilization dose is absorbed in the article required. Such as the use of radiation and sterilization items are together radioactive dosimeters, dosimeter to put the provisions of the site. Dosimeter in the early installation using standard calibration source and regularly re- calibration.
When 60Co-γ ray radiation sterilization validation, verification testing in addition to biological indicator, it should also confirm that the radiation dose distribution of load and loading chamber sterilization, sterilization items absorbed dose and the maximum and minimum absorption dose distribution uniformity, loading patterns sterilization chamber and other items sterilized items. Commonly used as a biological indicator Bacillus pumilus spores (Spores of Bacillus pumilus).

With the development of new energy vehicles, lead-acid start battery is being replaced by Lithium Iron Phosphate batteries which have the advantage of  high charge / discharge performance, lighter weight, smaller size, longer cycle life, no pollution etc.
After two years’ research and tesing on start batteries, we build up a professional team which successfully designed a series of car start battery (12v20Ah, 12v40Ah, 12v60Ah, 12v80Ah)with BMS built in .

Rainwater recycling involves collecting rainwater from a building’s roof or from any other surface, including nowadays permeable pavements and garden lawns. The rainwater then passes through a filter, which eliminates debris, and is stored in a holding tank placed either underground or the side of a building or in the loft.
This saved water can be pumped to places where it is needed. Since the water collected by most rainwater harvesting systems is not drinkable (without substantial treatment), plumbing regulations dictate that the collected rainwater be passed through a dedicated pipe system, and not the building’s drinking water system.

A lithium battery is mainly composed of two parts: cells and BMS (Battery Management System).
Lithium cells consist of the anode, separator, cathode,electrolyte, and the materials are rolled or laminated to make into the cells.
