Chemical stability of swimming pool filter support non-woven fabrics
Non-woven fabric, also called non-woven fabric, is a kind of fabric that does not require spinning There are many types of fabrics on the market now, and swimming pool filter element support non-woven fabric is one of its many types.
The hot-melt lamination composite process mainly appears in filter material manufacturers. That is, the non-woven fabric and the fiberglass filter material are bonded together through hot melt glue at a certain temperature and pressure. There are certain differences in the gluing process between foreign countries and domestic countries. In foreign countries, the hot melt glue particles are melted first. Then spray it in the form of droplets or fibers between the fiberglass filter material and the non-woven fabric, and then use hot-pressing compounding equipment for compounding.
The non-woven fabric supporting the swimming pool filter element has good heat resistance, with a melting point of 164~170℃, and the product can be sterilized at temperatures above 100℃. It will not deform at 150℃ without being affected by external force. The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and its heat resistance is not as good as PE. It also has good chemical stability. In addition to being corroded by acids, it is relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell non-woven fabrics. The chemical stability varies with the degree of crystallinity. The increase has also improved.
