1. Nhanganyaya
Polyvinyl chloride (PVC) yakashandiswa zvakanyanya mundima yehupenyu nekuda kwekuita kwayo kwakanakisa, mutengo wakaderera, simba repamusoro uye kukwirira kwekuora, uye kushandiswa kwayo ichikamu chechipiri chikuru chezvigadzirwa zvepurasitiki mushure me polyethylene.Zvisinei, nekuda kwekusagadzikana kwePVC, zvinowedzera zvinoda kuwedzerwa, iyo inonyanya kukosha ndeye plasticizer.Iwo mapurasitiki anoshandiswa muPVC anonyanya phthalate esters, uye madiki mamorekuru epurasitiki anomiririrwa neDOP ane yakanakisa plasticizing maitiro uye kuenderana kwakanaka nemapurasitiki, asi iwo zvakare ane akawanda zvikanganiso.Ivo vanozotamira pamusoro pezvigadzirwa zvepurasitiki panguva yekushandiswa kwenguva refu kwezvinhu, vane zvakakomba kudhirowa munzvimbo dzakakosha, uye vanowanzotadza mukutonhora kana kupisa kwakanyanya, uye kushomeka uku kunoderedza zvakanyanya nguva yekushandisa uye kushanda kwezvigadzirwa.
Kubva pakuona kwekushanda kwakawanda, kuchengetedza kwezvakatipoteredza uye kusimba, kambani yedu inogadzira akateedzana ezvekuwedzera polymer, achichinja huremu hwemamorekuru ezvekuwedzera kuti avandudze kusimba uye kupisa kwakanyanya kupikisa kwezvinowedzera, uye kuita kuti zvienderane nePVC kuburikidza ne Kuwedzerwa kwemamonmers anoshanda kuvandudza kuramba kwekufamba uye kuburitsa kuramba kwezvinowedzera.Isu takawedzera iyo yakasanganiswa yekuwedzera kuPVC zvinhu kuti tiongorore magadzirirwo eiyi polymer yekuwedzera yakaiswa kuPVC mukuenzanisa nediki molecule DOP.Zvikuru zvakawanikwa ndeizvi: Muchidzidzo ichi, takasarudza emulsion polymerization kuti tigadzirise akatevedzana methacrylate polymers achishandisa methyl methacrylate (MMA), styrene (st) uye acrylonitrile (AN) secopolymer monomers.Isu takadzidza pesvedzero yeakasiyana ekutanga, emulsifiers, kuita tembiricha uye chiyero chechikamu chimwe nechimwe pa polymerization process mu emulsion polymerization, uye pakupedzisira takawana yakakwira molecular uremu plasticizing aids ADX-1001 uye yakaderera molecular uremu plasticizing aids ADX-1002, uye iyo zvigadzirwa zvine kuwirirana kwakanaka nePVC, iyo inogona kunyatso kudzikisa nguva yePVC resin, kuderedza kupisa kwekushisa, kuita kuti zvigadzirwa zvipfave uye zviise pakugadzira jekiseni.
2 Recommended Dosage
Huwandu hwemapurasitiki anobatsira ADX-1001 zvikamu gumi pazvikamu zana zvehuremu hwePVC resin.
