Ndeupi musiyano uripo pakati pePS zvinhu uye AS zvinhu zvemapurasitiki emvura makapu

Ndezvipi zvinhu zviri kushandiswa pari zvino pamakapu emvura epurasitiki pamusika, zvakadai seTritan, PP, PPSU, PC, AS, etc. PS haiwanzotaurwa sechinhu chakajairika chepurasitiki yemvura makapu. Ndakasanganawo nezvinodiwa zvekutenga zvemutengi wekuEurope. Mupepeti aikwanisa kuwana zvinhu zvePS. Shamwari zhinji dziri kuita kutengeserana kune dzimwe nyika dzinoziva kuti musika wese weEurope, wakadai seGermany, urikumanikidza mapurasitiki ekurambidza. Chikonzero ndechekuti zvinhu zvepurasitiki hazvisi nyore kuora uye kudzokororwa, uye zvinhu zvakawanda zvepurasitiki zvine bisphenol A, izvo zvinogona kukuvadza muviri wemunhu mushure mekugadzirwa mumakapu emvura. Semuenzaniso, zvinhu zvePC, kunyangwe zvirinani pane AS nePS mune mamwe maitiro ekuita, zvinorambidzwa kubva kumusika weEurope kugadzira mabhodhoro emvura nekuti ane bisphenol A.

PS, mumashoko evaraidzo, is thermoplastic resin iyo isina ruvara uye yakajeka ine yakakwirira transmittance. Zvichienzaniswa nemidziyo yepurasitiki yataurwa pamusoro apa, mutengo wayo wakaderera ndiwo mukana wayo, asi PS haina kusimba uye ine hurombo husina kusimba, uye chinyorwa ichi chine kaviri Mvura makapu akagadzirwa ne phenol A uye PS zvinhu hazvigone kuzadzwa nepamusoro-tembiricha inopisa mvura, kana zvisina kudaro. ivo vachaburitsa bisphenol Aharmful substances.

AS, acrylonitrile-styrene resin, polymer zvinhu, isina ruvara uye yakajeka, ine yakakwirira transmittance. Kana ichienzaniswa nePS, inoshingirira kudonha, asi haina kusimba, kunyanya isingadzivirirwe nekusiyana kwekushisa. Kana iwe ukakurumidza kuwedzera mvura inotonhora mushure memvura inopisa, pamusoro pezvinhu zvichave Kana pane kuputika kwakajeka, kuchaputikawo kana kuiswa mufiriji. Iyo haina bisphenol A. Kunyange zvazvo kuizadza nemvura inopisa kuchaita kuti kapu yemvura iparadze, haizosununguri zvinhu zvinokuvadza, saka inogona kudarika EU kuedza. Mutengo wezvinhu wakakwira kupfuura PS.
Nzira yekutonga sei kubva pachigadzirwa chakapedzwa kana mukombe wemvura wakagadzirwa nePS kana AS zvinhu? Kuburikidza nekutarisa, zvinogona kuoneka kuti iyo isina ruvara uye yakajeka kapu yemvura yakagadzirwa nezvinhu zviviri izvi inozogara ichiratidza bhuruu. Asi kana iwe uchida kunyatsoona kana iri PS kana AS, unofanirwa kushandisa hunyanzvi hwekuyedza michina.
