Mafotokozedwe Akatundu:
Dibutyl phthalate (DBP) ndiye pulasitiki yomwe imagwiritsidwa ntchito kwambiri pa PVC, yomwe ingapangitse kuti zinthuzo zikhale zofewa bwino koma zosakhalitsa.Kukhazikika, kukana kusinthasintha, kumamatira ndi kukana madzi kuli bwino kuposa mapulasitiki ena.Dibutyl phthalate imagwiritsidwa ntchito ngati chowonjezera mu zomatira ndi inki zosindikizira.Imasungunuka m'mitundu yosiyanasiyana ya organic solvents, monga mowa, ether ndi benzene.DBP imagwiritsidwanso ntchito ngati ectoparasiticide.
Dibutyl phthalate (DBP) ndi plasticiser yabwino kwambiri, ndiyo kupanga kwakukulu komanso kugwiritsa ntchito mapulasitiki m'kalasi, ndicholinga chambiri.Imakhala ndi kusungunuka kwamitundu yambiri ya resin ndipo imagwiritsidwa ntchito ngati pulasitiki wamkulu wokhala ndi utoto wopepuka, kawopsedwe kakang'ono, kawopsedwe kabwino ka magetsi, kusakhazikika kochepa, kununkhira kochepa komanso kukana kutentha.
Ntchito Yogulitsa:
1.Chida ichi ndi plasticiser, chosakhala ndi poizoni.
2.Imagwiritsidwa ntchito makamaka ngati PVC plasticiser, yomwe imatha kupanga zinthuzo kukhala zosinthika bwino.Chifukwa cha kutchipa kwake komanso kusinthika kwabwino, imagwiritsidwa ntchito kwambiri ku China, pafupifupi yofanana ndi DOP.Komabe, kusasunthika kwake ndi kutulutsa madzi kumakhala kwakukulu, motero kukhazikika kwa zinthuzo kumakhala kovutirapo, ndipo kugwiritsidwa ntchito kwake kuyenera kuchepetsedwa pang'onopang'ono.
3.This mankhwala ndi plasticiser kwambiri kwa nitrocellulose, ndi amphamvu gelation luso.Ntchito ❖ kuyanika nitrocellulose, ali kwambiri kufewetsa zotsatira, bata ndi adhesion.Itha kugwiritsidwanso ntchito ngati polyvinyl acetate, alkyd resin, ethyl cellulose, mphira wachilengedwe komanso wopangidwa, komanso magalasi a organic ndi plasticiser.
