Kev siv HPMC F 50
EipponCell HPMC F 50 yog ib qho tseem ceeb dispersant siv hauv kev lag luam polyvinyl chloride (PVC).Thaum lub sij hawm ncua kev kawm ntawv polymerization ntawm vinyl chloride, nws ua ntau yam haujlwm.Ua ntej, nws txo cov kev sib tshuam ntawm cov yas chloride monomer (VCM) thiab dej, ua kom yooj yim rau kev sib cais thiab ruaj khov ntawm VCM hauv nruab nrab aqueous.Qhov thib ob, nws tiv thaiv kev sib koom ua ke ntawm VCM cov tee dej ntawm thawj theem ntawm polymerization.Thaum kawg, nws inhibits coalescence ntawm polymer hais nyob rau hauv nruab nrab thiab tom qab theem ntawm cov txheej txheem.Nyob rau hauv lub ncua kev kawm ntawv polymerization system, EipponCell HPMC F 50 plays ib tug dual lub luag hauj lwm ntawm dispersing VCM thiab xyuas kom meej stability.
Polyvinyl chloride (PVC) resin nrog ib tug tsawg degree ntawm polymerization feem ntau yog hais txog PVC resin nrog ib tug polymerization degree hauv qab 800. Hom resin, vim nws tsis tshua muaj molecular hnyav, siab pom tseeb ntom, zoo yaj fluidity, luv plasticizing lub sij hawm, thiab yooj yim. ntawm kev ua, pom kev siv dav hauv cov ntawv tsim, kev txhaj tshuaj molding yeeb nkab fittings, tshuab moulding, thiab kev tsim cov khoom hloov kho (xws li chlorinated polyvinyl chloride los ntawm kev sib sib zog nqus chlorination ntawm vinyl chloride resin), thiab lwm yam.Txawm li cas los xij, PVC resin nrog rau qib qis ntawm polymerization muaj qhov tsis tshua muaj porosity thiab compact resin hais.Cov zaj duab xis particle tsim los ntawm graft copolymerization ntawm dispersants thiab vinyl chloride nyhav kuj tuab, uas tuaj yeem cuam tshuam cov resin kev ua tau zoo thiab kev hloov kho tom qab.
