Kodi njira zogwiritsira ntchito zowongolera thovu la PVC ndi ziti?

Mu njira yopangira thovu ya PVC, kuti pakhale chinthu chofanana, chosalala, komanso chodziyimira pawokha cha kapangidwe ka maselo, kuwonjezera pa kugwiritsa ntchito zosinthira thovu monga zothandizira kukonza ACR, zosinthira thovu za PVC nthawi zambiri zimagwiritsidwanso ntchito mu njira yopangirayi. Nthawi zina, zothamangitsa thovu monga zitsulo monga zinc oxide ndi lead oxide, mchere wa organic acid monga zinc stearate, ndi zotumphukira za urea zimawonjezedwanso (kuti zisinthe kutentha kwa thovu). Mlingo wa chowongolera thovu nthawi zambiri umakhala 4% -8% (kutengera kuchuluka kwa resin), komwe kumafunika kufananizidwa ndi zotumizira thovu (monga AC yellow foaming agent, NC white foaming agent). Kupanga mbale zokhuthala kumafuna kuwonjezeka kwa kuchuluka kwa chothandizira thovu cha NC chotsika kutentha (chiŵerengero cha magawo 1.2 NC+0.5 AC) kuti tipewe kutulutsidwa kwa mpweya wambiri mtsogolo zomwe zimapangitsa kuti thovu lisweke; Kuwongolera kuchulukana kumafuna kuyanjanitsa kupanga gasi ndi kutentha kwa kutentha.
Chowongolera thovu cha PVC kwenikweni ndi polima ya acrylate lotion. Chili ndi makhalidwe onse a zothandizira processing PVC, koma kulemera kwake kwa molekyulu kumakhala kwakukulu kuposa kwa zothandizira processing PVC. Mu ndondomeko ya PVC yotulutsa thovu, kuwonjezera chowongolera thovu cha PVC kumatha kuwonjezera mphamvu yosungunuka ya zinthu za PVC, potero kuletsa kuphatikizana kwa thovu ndikupeza zinthu za thovu za PVC zodzazidwa ndi thovu. Nthawi yomweyo, chingalimbikitsenso pulasitiki ya PVC ndikuwonetsetsa kuti kusungunuka kumakhala kosalala bwino.
Posankha ma modifier a PVC thovu, muyenera kuganizira kwambiri kugwiritsa ntchito ma modifier osiyanasiyana a thovu pa PVC yokhala ndi madigiri osiyanasiyana a polymerization, monga PVC-700, PVC-800, ndi PVC-1000. Zinthu zosiyanasiyana, monga ma foam board, ma foam thick board, ma foam board a pulasitiki, ma lead plastic thovu board, ndi zina zotero, zimafuna kugwiritsa ntchito ma foam modifiers osiyanasiyana. Chifukwa chakuti ma PVC thovu agents nawonso ndi acrylic compounds okhala ndi zinthu zothandizira processing, muyeneranso kuganizira za mafuta omwe ali mkati ndi kunja kwa formula mukamagwiritsa ntchito. Bangtai Petrochemical Foam Regulator ikukwaniritsa zosowa zanu zosiyanasiyana pazinthu. Kuti mudziwe zambiri za zinthu zokhudzana ndi ma PVC foam regulators, chonde musazengereze kutiyimbira foni!
