In our daily life, many chemicals are actually not edible. Because these items are not only indigestible to the body, but also affect the normal functioning of various organs in the body. Generally speaking, adults rarely ingest food by mistake, but for some babies who do not have much common sense, it is easy for them to ingest food by mistake due to the negligence of their parents. So, what should you do if you accidentally eat SpongeBob? Sponge is a porous material with good water absorption and can be used to clean items. Commonly used sponges are made from wood cellulose fibers or foamed plastic polymers. In addition, there are also natural sponges made from sponge animals, most of which are used for body cleaning or painting. In addition, there are three other types of synthetic sponges made of materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material with no obvious pores) and polyester. A. Mixing the foaming resin, foaming aid and adhesive resin (which gives the finished product adhesiveness); B. Carry out foaming process. 80 parts of ethylene vinyl acetate (EVA), 20 parts of APAOPT3385, 20 parts of azodicarbonamide, 19 parts of CaCO and 0.6 parts of diisopropylbenzene peroxide are mixed together, placed in a mold for foaming, and the closed cells are broken by mechanical force to obtain a foamed sponge. Its density (d) is 0.028 g/cm3 and its 25% compression hardness is 1.9 KPa. Just like foaming, the same material and different manufacturing processes will produce different things. PU sponge mainly includes polyester and polyether types which can be cut into slices or rolls, and can also be processed by compounding, hot pressing and blasting according to customer requirements. PU sponge has the characteristics of heat preservation, heat insulation, sound absorption, shock absorption, flame retardancy, anti-static, good breathability, etc., so it is involved in various industries, including the automotive industry, battery industry, cosmetics industry, bra underwear manufacturing industry and high-end furniture manufacturing industry. |
