Fa'aaogaina le touchpad

Taua ole Hydroxypropyl MethylCellulose (HPMC) ile PVC

Matou te faʻamaoni ma manumalo-manumalo e avea ma taʻiala faʻatino, ma faʻatautaia pisinisi uma ma le faʻatonuina ma le faʻaeteete.

O oloa Hydroxypropyl Methyl Cellulose o loʻo i ai le maualuga o le taumafaina i le vaega o le faʻamalologa polymerization o le vinyl chloride i Saina. I le faʻamalologa polymerization o le vinyl chloride, o le faʻasalalauina o loʻo i ai se aafiaga tuusaʻo i luga o le oloa, PVC resin, ma luga o le lelei o ana gaioiga ma oloa. O le HydroxypropylMethylCellulose e fesoasoani e faʻaleleia le faʻamautuina o le vevela o le resin ma pulea le tufatufaina o le tele o vaega.PVC resin faia mai le tulaga maualuga HydroxypropylMethylCellulose e le gata e mafai ona mautinoa le laina faatinoga ma tulaga faava o malo, ae e mafai foi ona i ai le lelei o meatotino faaletino, meatotino vaega sili ona lelei ma le lelei liusua amio rheological.

 

I le gaosiga o resini gaosia, e pei o le polyvinyl chloride, polyvinylidene chloride, ma isi copolymers, o le polymerization taofia e sili ona masani ona faʻaaogaina ma e tatau ona faʻaogaina monomers hydrophobic faʻamalolo le tumau i le vai. I le avea ai o se polymers solu vai, HydroxypropylMethylCellulose oloa e sili ona lelei le gaioiga i luga ma galue o ni mea e puipuia ai colloidal agents. HydroxypropylMethylCellulose e mafai ona puipuia lelei vaega polymeric mai le gaosia ma agglomeration. E le gata i lea, e ui lava o le HydroxypropylMethylCellulose o se polymer soluble vai, e mafai ona solule teisi i monomers hydrophobic ma mafai ona faateleina le porosity monomer mo le gaosiga o vaega polymeric.

E le gata i lea, o suʻesuʻega ua faʻaalia i le gaosiga o le PVC, o pisinisi eseese e faʻaogaina ai le faʻasalalauina o faiga faʻasalalau, o le mea lea e ese foi le faʻaogaina o mea faʻapipiʻi fafo o le PVC, ma o le mea lea e mafai ai e le HydroxypropylMethylCellulose ona aʻafia le gaioiga o le PVC resins. I totonu o le faʻapipiʻi faʻasalalauga faʻapipiʻi, o le faʻamalolo PVC resin saunia mai le sui faʻasalalau tuʻufaʻatasia o le polyvinyl alcohol (PVA) faʻatasi ai ma le eseese o le alcoholysis ma le polymerization tikeri ma le hydroxypropyl methyl cellulose (HPMC) atonu e eseese aʻafiaga i le gaioiga gaioiga. O suʻega ua faʻaalia ai o le faʻaogaina o le HydroxypropylMethylCellulose ma le KP-08 / KZ-04 faʻatasi ai ma le tikeri o le alcoholysis o le 68% -75% e sili atu ma aoga foi mo le porosity o resini ma le absorption o plasticizers.
