Kodi ntchito za PVC processing aids ndi chiyani?

1. PVC processing aids PA-20 ndi PA-40, monga katundu ACR kunja, chimagwiritsidwa ntchito mu PVC mandala mafilimu, mapepala PVC, PVC particles, PVC hoses ndi zinthu zina kuti bwino patsogolo kubalalitsidwa ndi matenthedwe processing ntchito ya PVC zosakaniza, kuwala pamwamba, bwino kuchepetsa kutulutsa zinyalala, ndi kuthetsa mavuto otaya zizindikiro ndi mfundo krustalo sachedwa kuchitika kupanga.
Chifukwa cha kulemera kwake kwa ma molekyulu apamwamba kwambiri, PA-40 imagwiritsidwa ntchito kwambiri ngati chowongolera chotulutsa thovu m'mabodi a thovu a PVC, mapaipi a thovu a PVC, ndi zinthu zina, zomwe zimapangitsa kutulutsa thovu yunifolomu komanso mtundu wapamwamba wazinthu.
2. Kusintha kwa Impact MBS Impact resistant MBS resin imagwiritsidwa ntchito makamaka pokonza ndi kupanga PVC kuti ipititse patsogolo mphamvu zake popanda kuwononga chikhalidwe cha PVC. Chifukwa cha magawo ake ofanana solubility kwa PVC, awiriwo ali wabwino thermodynamic ngakhale, yodziwika ndi mkulu zimakhudza mphamvu, kukana kutentha, ndi mitundu mitundu ya PVC m'chipinda kapena kutentha otsika. Transparent modifier MBS Transparent MBS resin imagwiritsidwa ntchito makamaka pokonza ndi kupanga zinthu zowonekera za PVC, kuwongolera mphamvu zawo popanda kuwononga mawonekedwe achilengedwe azinthu zowonekera za PVC. Refractive index yake ndi yofanana ndi PVC, ndipo kugwiritsa ntchito MBS ngati PVC impact modifier sikungakhudze kuwonekera kwa PVC. Ndizinthu zabwino kwambiri zowongolera kukana kwamphamvu kwa PVC ndikupanga zinthu zowonekera. Poyerekeza ndi makampani ena, MBS yathu ili ndi kukana kwakukulu, kugwirizanitsa bwino, komanso kukana kuvala kwa MBS yowonjezera BLD-81 (zosintha zowonongeka, zomwe zimayang'ana pa mapaipi a PVC ndi zoyikira) zimagwiritsidwa ntchito kupititsa patsogolo mphamvu ndi kukana kwa nyengo kwa zinthu za mbiri ya PVC.
