1 Mawu Oyamba
Polyvinyl kolorayidi (PVC) wakhala chimagwiritsidwa ntchito kwambiri m'munda wa moyo chifukwa cha ntchito zake zabwino kwambiri, mtengo wotsika, mphamvu mkulu ndi mkulu dzimbiri kukana, ndipo ntchito yake ndi yachiwiri yaikulu gulu la mankhwala pulasitiki pambuyo polyethylene.Komabe, chifukwa cha kusayenda bwino kwa PVC, zowonjezera ziyenera kuwonjezeredwa, zomwe ndizofunikira kwambiri ndi plasticizer.Mapulasitiki omwe amagwiritsidwa ntchito mu PVC ndi makamaka phthalate esters, ndipo mapulasitiki ang'onoang'ono a molekyulu omwe amaimiridwa ndi DOP ali ndi zotsatira zabwino kwambiri za pulasitiki komanso zogwirizana bwino ndi mapulasitiki, koma amakhalanso ndi zofooka zambiri.Adzasamukira kumtunda wa zinthu zapulasitiki pakugwiritsa ntchito kwa nthawi yayitali, kukhala ndi m'zigawo zazikulu m'malo apadera, ndipo amatha kulephera m'malo ozizira kapena kutentha kwambiri, ndipo zofookazi zimachepetsa kwambiri kugwiritsa ntchito nthawi ndi magwiridwe antchito.
Malinga ndi magwiridwe antchito ambiri, chitetezo cha chilengedwe komanso kukhazikika, kampani yathu imapanga zowonjezera zowonjezera za polima, kusintha kulemera kwa maselo azinthu zowonjezera kuti zikhale zolimba komanso kutentha kwambiri kukana kwa zowonjezera, ndikuzipanga kuti zigwirizane ndi PVC kudzera mu Kuwonjezera kwa ma monomers ogwira ntchito kuti apititse patsogolo kukana kwa kusamuka ndi kukana kwa m'zigawo za zowonjezera.Tidawonjezera chowonjezera chazinthu za PVC kuti tifufuze momwe chowonjezera cha polimachi chimagwiritsidwa ntchito ku PVC poyerekeza ndi kamolekyu kakang'ono ka DOP.Zomwe tapeza ndi izi: Mu phunziroli, tinasankha emulsion polymerization kuti tipange ma polima angapo a methacrylate pogwiritsa ntchito methyl methacrylate (MMA), styrene (st) ndi acrylonitrile (AN) monga copolymer monomers.Taphunzira kutengera kwa oyambitsa osiyanasiyana, ma emulsifiers, kutentha komwe kumayendera komanso kuchuluka kwa gawo lililonse panjira ya polymerization mu emulsion polymerization, ndipo pamapeto pake tidapeza zida zolemera zama cell a ADX-1001 ndi zida zotsika zama cell apulasitiki ADX-1002, ndi mankhwala ndi ngakhale bwino ndi PVC, amene angathe kuchepetsa nthawi plasticizing utomoni PVC, kuchepetsa kutentha processing, kupanga mankhwala ofewa ndi ntchito akamaumba jekeseni.
2 Analimbikitsa Mlingo
Kuchuluka kwa zida za plasticizing ADX-1001 ndi magawo 10 pa magawo 100 olemera a utomoni wa PVC.
3 Kuchita Kufananiza Ndi Plasticizer DOP
1. Konzani zinthu za PVC molingana ndi ndondomeko yomwe ili mu tebulo ili pansipa

2. Kukonza masitepe a zinthu za PVC: Phatikizani zomwe zili pamwambazi padera ndikuwonjezera pawiri ku rheometer.
3. Fananizani zotsatira za ADX-1001 ndi DOP pa kukonza kwa PVC poyang'ana deta ya rheological.
4. Zomwe zimapangidwira za PVC mutatha kuwonjezera mapulasitiki osiyanasiyana zikuwonetsedwa mu Table 4 pansipa.

| Ayi. | Nthawi yopangira pulasitiki (S) | Balance Torque (M[Nm]) | Liwiro Lozungulira (rpm) | Kutentha (°C) |
| DOP | 100 | 15.2 | 40 | 185 |
| ADX-1001 | 50 | 10.3 | 40 | 185 |
| ADX-1002 | 75 | 19.5 | 40 | 185 |
4 Mapeto
Pambuyo potsimikizira zoyeserera, zida zopangira pulasitiki zopangidwa ndi kampani yathu zimatha kufupikitsa nthawi ya pulasitiki ya PVC utomoni ndikuchepetsa kutentha kwa kutentha poyerekeza ndi DOP.
