PP phula, yomwe imadziwikanso kuti sera ya polypropylene, imagwiritsidwa ntchito kwambiri chifukwa cha kuzizira kwambiri, kukana kutentha, kukana mankhwala, komanso kuvala.Pakupanga kwabwinobwino, sera iyi imatha kuwonjezedwa mwachindunji ngati chowonjezera pakukonza kwa polyolefin, kukulitsa kung'anima ndi kukonza kwazinthu.Monga mafuta, imakhala ndi mankhwala okhazikika komanso magetsi abwino.Polyethylene imagwirizana bwino ndi polyethylene, polypropylene, polyvinyl acetate, mphira wa ethylene propylene, ndi mphira wa butyl.Itha kusintha kutulutsa kwa polyethylene, polypropylene, ndi ABS, ndikuwongolera magwiridwe antchito a polymethyl methacrylate ndi polycarbonate.Poyerekeza ndi mafuta ena akunja, imakhala ndi mphamvu yamkati yamafuta a PVC.

Polypropylene serandi otsika molecular kulemera polyethylene homopolymer kapena copolymer kwambiri ntchito zokutira.The otchedwa sera amatanthauza polima akuyandama mu mawonekedwe a microcrystals mu ❖ kuyanika pamwamba, kusewera ntchito yothandiza ofanana koma zosiyanasiyana kuposa parafini.
Sera ikatenthedwa, ufa umasungunuka ndikubalalika mu utomoni wosungunula.Filimuyo ikazizira, imatuluka mu utomoni.Sera ya polypropylene imagwiritsidwa ntchito kwambiri m'mafakitale monga inki, zikopa, mapulasitiki aumisiri, nsalu, kusindikiza ndi utoto, zomatira, ndi zotulutsa.Makhalidwe ndi ntchito za sera ya polypropylene:
1. Sera ya polypropylene imachokera ku zokutira kusungunuka panthawi yopanga filimu ya zokutira ufa, kupanga tinthu ting'onoting'ono tomwe timayandama pamwamba pa zokutira, zomwe zimagwira ntchito mu kapangidwe, kutha, kusalala, kukana kukangana, kukana kumamatira, ndi kukana madontho. .

2. Kutha kwa mawonekedwe: Pamene filimu yokutira ikazizira, tinthu tating'ono ting'onoting'ono timatulutsa timadzi tambiri tomwe timatulutsa timadzi timene timatulutsa timadzi timene timatulutsa ndipo timapita pamwamba pa zokutira, zomwe zimapangitsa kuti ziwonongeke.Mu zokutira za ufa.Mitundu yosiyanasiyana ya sera imakhala ndi zotsatira zosiyana pa glossiness.

3. Sera ya polypropylene ilipo pamwamba pa ❖ kuyanika mu mawonekedwe a particles omwazikana, kuchepetsa mkangano coefficient wa ❖ kuyanika.Chinthu chikagunda pamwamba pa zokutira, kutsetsereka kumakhala kokulirapo kuposa kukanda, kumachepetsa kukangana ndi kupukuta, komanso kumamatira kulimba kwa gloss.
4. Sera ya polypropylene imathandizira kunyowetsa ndi kubalalitsidwa kwa mitundu ya pigment, kumapangitsa kuti utoto ukhale wolimba.Kuwonjezera 1% -3% akhoza kuwonjezera utoto mphamvu ya inki ndi 10% -30%.
5. Perekani mawonekedwe omasuka, anti adhesion, ndi kukana madontho kwa zokutira.Zinthu zakunja zikakumana ndi zokutira, nthawi zambiri zimasiya zizindikiro zakuda.Sera pamwamba pa zokutira zimatha kuchepetsa banga kapena kupanga kukhala kosavuta kupukuta.Sera ya polypropylene imakhala ndi mawonekedwe a kukhuthala kochepa, kufewetsa kwambiri, komanso kulimba kwabwino.Pangani kukhala dispersibility wabwino ndi lubricity kunja, ndipo akhoza kusintha processing ndi kupanga dzuwa la mankhwala.

Waukulu ntchito osiyanasiyana polypropylene sera: chimagwiritsidwa ntchito popanga mtundu masterbatches, granulation, pulasitiki zitsulo, mapaipi PVC, otentha Sungunulani zomatira, mphira, kupukuta nsapato, lighteners zikopa, kutchinjiriza chingwe, sera pansi, mbiri pulasitiki, inki. , jekeseni akamaumba ndi mankhwala ena.
