1 Folasaga

Polyvinyl chloride (PVC) ua faʻaaogaina lautele i le fanua o le olaga e ala i le lelei o lona faʻatinoga, tau maualalo, malosi maualuga ma le maualuga o le pala, ma o lona faʻaaogaina o le vaega lona lua sili ona tele o oloa palasitika pe a uma le polyethylene.Ae ui i lea, ona o le le lelei o le faʻaogaina o le PVC, e manaʻomia ona faʻaopoopo mea faʻaopoopo, o le mea sili ona taua o le plasticizer.O palasitika o loʻo faʻaaogaina i le PVC e masani lava o le phthalate esters, ma o laʻititi laʻititi mole mole o loʻo faʻatusalia e le DOP e sili ona lelei le faʻapipiʻiina ma le fetaui lelei ma palasitika, ae e tele foi a latou faaletonu.O le a latou faimalaga atu i luga o mea palasitika i le taimi o le faʻaaogaina umi o meafaitino, e iai se faʻalavelave faʻapitoa i siosiomaga faʻapitoa, ma e faigofie ona toilalo i le malulu poʻo le maualuga o le vevela siosiomaga, ma o nei faaletonu e matua faʻaitiitia ai le faʻaaogaina o le taimi ma galuega o oloa.

Mai le vaaiga o le tele-functionality, puipuiga o le siosiomaga ma le tumau, ua mamanuina e la matou kamupani se faasologa o mea faaopoopo polymer, suia le mamafa mole mole o mea faaopoopo e faaleleia atili ai le tumau ma le maualuga o le vevela o mea faaopoopo, ma ia sili atu ona fetaui ma le PVC e ala i le fa'aopoopoina o monomers fa'atino e fa'aleleia atili ai le femalaga'iga ma le fa'asaoina o mea fa'aopoopo.Na matou faʻaopoopoina le faʻapipiʻi faʻapipiʻi i mea PVC e suʻesuʻe ai le gaioiga o le gaioiga o lenei mea faʻapipiʻi polymer e faʻaaogaina i le PVC pe a faʻatusatusa i le DOP mole laʻititi.O faʻamatalaga autu o loʻo taua i lalo: I lenei suʻesuʻega, na matou filifilia le polymerization emulsion e faʻapipiʻi ai se faasologa o polymers methacrylate e faʻaaoga ai le methyl methacrylate (MMA), styrene (st) ma le acrylonitrile (AN) e avea ma monomers copolymer.Ua matou suesueina le aafiaga o initiators eseese, emulsifiers, vevela tali ma le fua faatatau o vaega taitasi i luga o le faagasologa polymerization i polymerization emulsion, ma iu ai ina maua le maualuga mole mamafa plasticizing fesoasoani ADX-1001 ma le maualalo molecular mamafa plasticizing fesoasoani ADX-1002, ma le oloa e iai le fetaui lelei ma le PVC, lea e mafai ona faʻaitiitia lelei le taimi faʻapipiʻi o le PVC resin, faʻaitiitia le vevela o le gaosiga, faʻamalulu oloa ma faʻaoga i le tui tui.

2 Fusi Fautuaina

Ole aofaiga ole palasitika fesoasoani ADX-1001 e 10 vaega ile 100 vaega mamafa ole PVC resin.

3 Fa'atusatusaga Fa'atinoga ma Plasticizer DOP

1. Saunia oloa PVC e tusa ai ma le fua faʻatatau i le laulau o loʻo i lalo

2. La'asaga o le fa'agaioiina o oloa PVC: Fa'aopoopo fa'atasi mea fa'atatau o lo'o i luga ma fa'aopoopo le fa'aputu i le rheometer.
3. Faʻatusatusa le aʻafiaga o le ADX-1001 ma le DOP ile faʻaogaina o le PVC e ala ile mataʻituina o faʻamatalaga rheological.
4. O le gaosiga o meatotino a le PVC pe a uma ona faʻapipiʻi mea faʻapipiʻi eseese o loʻo faʻaalia i le Table 4 i lalo.
