Nowadays, the rapid development of various kinds of science and technology in the world today, the endless variety of things in your life may be just some very humble things, but the amount of technology you know, minutes scare you a big jump. Foam is the rapid development of science and technology in the past century, it has entered every household, it has become an indispensable part of our lives, and small to a one-time appliances, large to a variety of auto parts, aircraft spare parts And so on, just like you to share the following foam it.
The price of foam:
The price of foam is actually very cheap, disposable appliances is made of plastic foam is generally between 1 yuan to 10 yuan, of course, some of the higher technological content of the foam film will be more expensive, generally in a thousand to ten thousand between.
The main use of foam:
(1) packaging areas: electronic appliances, components, household appliances and other requirements of higher protection and packaging materials.
(2) vehicle field: automotive interior decoration, ceiling, dashboard, cover the board, coolers, flooring and other materials.
(3) culture and sports, groceries: school teaching materials, children's toys, sports mats, surfboards, swimming life jackets, float and cushioning materials; kitchen sinks, mats, bath covers and slippers, hats, etc. The
(4) cold room machinery, water tanks, reservoir insulation materials; central air conditioning, air conditioning with insulation materials.
(5) building, civil area, roof, wall insulation, insulation, cushioning, anti-condensation, waterproof, leakproof, anti-corrosion materials; civil building all kinds of basic materials; antifreeze, shock buffer material; Mat material and so on.
Features of foam:
(1) the bulk density is very low, can reduce the weight of packaging, reduce transportation costs;
(2) has an excellent impact, vibration energy absorption, for cushioning shock packaging can greatly reduce the product damage;
(3) the temperature and humidity changes adaptability, to meet the general requirements of the packaging situation;
(4) low water absorption, hygroscopicity is small, good chemical stability, itself will not produce corrosion of the contents, and acid, alkali and other chemicals have a strong tolerance;
(5) low thermal conductivity, can be used for thermal insulation packaging, such as ice cream cups, fast food containers and insulation boxes;
(6) forming and processing, you can use molding, extrusion, injection molding methods such as a variety of foam pads, foam, sheet and so on. Easy to secondary molding processing, such as foam sheet can be made by thermoforming fast food containers and so on. In addition, the foam block may be self-adhesive with an adhesive or other material bonding, made of a variety of cushioning pads and so on.
We have a little thing around us even have so many uses, in fact, this is only a small part of the bubble only, with the development of science and technology, we have the absolute reason to believe that the type of foam will be more and more Of the plastic pollution will be less and less, this is the benefits of scientific and technological progress. Our pace of life is getting faster and faster, because we have entered the era of a global village, and I believe that with the rapid development of the times, the foam should occupy a more important role in our lives.
