FAQ

How do you test the resistance value of the aluminum foil of the capacitor?
Add a capacitor higher than the rated voltage of 20%, after 5 minutes without current, you can believe that the pressure qualified.
What is aluminum foil?Can it be decomposed by soil?
A kind of aluminum rolled into sheets of hot stamping material, the effect of stamping and silver foil stamping similar effects, it is also called the false silver. Because aluminum is soft, ductile, with silver white luster, if after rolling sheet,
Considerations for hand held aluminium foil sealing machine
1, this machine is not suitable for metal container and metal cap and anodized aluminum paint cover on the metal surface, no heating press button, otherwise it will damage the machine, such as metal cap and anodized aluminum paint cover, aluminum foil can be screwed on the bottle cap.2, this machine is in use, the operator should always pay attention to the temperature sensing head, such as hot hot hand (about 80 DEG C) should stop working for natural cooling or use a fan induction head alignment sensor head forced rapid cooling, the temperature sensing head down to room temperature (25 degrees Celsius) again start to work, so the sensor head of high temperature damage.3, the machine is equipped with automatic overheat protection function, when the internal temperature of overheating, green "overheating" bright lights, you should immediately can continue to work out in the standby light or cooling.
Relationship between capacitor capacity and aluminum foil
The dielectric constant is determined by the medium between the two platesIf the aluminum electrolytic capacitor, because the medium is AL2O3, the medium is very thin, if the voltage under certain conditions, the greater the aluminum foil area, the capacity is about large, so the capacity is basically determined by the area of aluminum foil!
Plastic container for food packing container
Single layer plastic film bag: the commonly used plastic varieties are high pressure polyethylene (low density polyethylene), low pressure polyethylene (HDPE), polypropylene, polyvinylidene chloride, etc. two. High pressure polyethylene film water resisting, softness and good low temperature resistance, and has the oxygen and carbon dioxide gas through the larger, which is suitable for the packaging of hygroscopic solid food, liquid food and frozen food, especially suitable for fresh vegetables, fruits and other packaging can maintain its "physiological respiration process, and keep the water caused by dry shrinkage metamorphism. But the high pressure polyethylene is poor in heat resistance, can not be heated, bactericidal temperature, and is not resistant to oil, low strength, so there is a certain limit in the application. Low pressure polyethylene is capable of over 100 degrees of thermal sterilization temperature and is resistant to grease. Therefore, the range of application is greater than that of high pressure polyethylene. Polypropylene film has excellent gas and moisture insulation, oil resistance, high transparency, smooth surface, can heat sterilization temperature above 100 DEG C, and can be made thinner and directional packaging films have high strength but low temperature resistance is poor, so it can be used for other food in the frozen food packaging. Poly two vinyl chloride generally made of biaxially oriented films, large thermal shrinkage and excellent gas barrier properties, which has high transparency, good elasticity, high strength, oil resistance and other properties, suitable for vacuum packaging, shrink packaging and frozen food packaging.
Aluminum foil lunch box microwave oven operation method?
1. before use, please tear open the aluminum cover (open the lid, not airtight heating).2., the food should be packed with lunch boxes (at least 80% of the total capacity of the whole lunch box).3. lunch boxes should be placed in the middle of the microwave oven turntable. (Note: if your microwave oven is a metal turntable, please insert a ceramic or glass mat underneath the lunch box.)4. lunch boxes can not touch the four walls of the microwave oven. (at least leave the wall of the microwave oven 2cm)5. microwave ovens can only use one aluminum foil lunch box at a time.
What causes the explosion of liquid nitrogen container liquid nitrogen tank?
Liquid nitrogen is a special industrial product, which has the characteristics of ultra low temperature, expansion, odorless and non-toxic. With the wide application of liquid nitrogen in precision industry, medicine and food, more and more accidents occur in liquid nitrogen container when filling and storing liquid nitrogen. The explosion of liquid nitrogen container causes damage to the equipment, which can lead to casualties. So what are the main causes of the explosion of liquid nitrogen container liquid nitrogen tank?.
Are aluminum foil lunch boxes much used in the country?
China is a developing country, which is not only economically, but also from the consumption of shut up embodied, everything from basic look, this is the market, but the cost for a small restaurant is a bit high. So it needs time to confirm.
