Pogwiritsira ntchito polypropylene fiber spinning, kugwiritsa ntchito sera ya polyethylene kumakhala kochepa. Kwa silika wamba wabwino wokanira ndi ulusi wapamwamba kwambiri, makamaka wa ubweya wofewa ngati chokanira chabwino ndi ma filaments a BCF oyenera kupaka zovala ndi zovala, polypropylene sera nthawi zambiri imakhala yabwino kuposa sera ya polyethylene.

Choyamba, chifukwa cha kusagwirizana pakati pa polypropylene ndi polyethylene, zimakhala zovuta kwambiri kupanga kusakaniza yunifolomu m'malingaliro ang'onoang'ono, zomwe zidzatsogolera kupatukana kwa gawo. Kachiwiri, chifukwa kusungunuka kwa sera ya polyethylene sera kwambiri kuposa sera ya polypropylene kapena polypropylene, ndizovuta kuthana ndi mawonekedwe osiyanasiyana osungunuka a ma polima awiriwa. Kusagwirizana ndi rheology yosayenera ya mankhwalawa kungayambitse kutha kwa kutha kwa ndondomeko yozungulira. Chifukwa cha zotsatira zoyipazi, nsalu zakuthupi za ulusi zimakulirakulira.
Panthawi imeneyi, m'pofunika kugwiritsa ntchito sera polypropylene ndi otsika mamasukidwe akayendedwe. Chifukwa cha kukhuthala kwake kochepa komanso kunyowa bwino, imatha kunyowetsa ma inki mu nthawi yochepa. Kuphatikiza apo, ulusi wa polypropylene ukatambasulidwa ndikuyika kutentha, umapezeka kuchokera ku kutentha kwa kutentha (nthawi zambiri pafupifupi 130c), womwe umakhala mkati mwa kutentha kosungunuka kwa sera ya polyethylene.

Chifukwa cha kusintha kwa crystalline kapangidwe ka polypropylene pulayimale CHIKWANGWANI, tingaone kuti wosungunuka polyethylene sera seeps kuchokera polypropylene masanjidwewo kuti CHIKWANGWANI pamwamba, ndipo si sera koyera, komanso pigment adzabweretsedwa pamwamba.
Pomaliza, kuyanjana kwa sera ya polypropylene ndi utomoni wa polypropylene ndikwabwino m'mbali zonse zazing'ono komanso zazikulu, ndipo sikukhudza kwambiri makina amakina. Pali mitundu iwiri ya sera polypropylene polymerized ndi metallocene chothandizira luso: mmodzi ndi homopolymer polypropylene sera, ndi zopangira ndi propylene; Wina ndi sera ya copolymerized polypropylene, yomwe imapangidwa ndi propylene ndi ethylene.
Nthawi zambiri, sera ya homopolymer polypropylene imakhala ndi malo osungunuka kwambiri, pakati pa 140-160c, kulemera kwa mamolekyulu kuchokera pa masauzande mpaka makumi masauzande, kutengera kukhuthala kwa Brookfield kuchokera pambiri mpaka masauzande, kuyera kwambiri komanso kuuma kwakukulu. Malo osungunuka a sera ya copolymer polypropylene nthawi zambiri amakhala pakati pa 80-110c, kukhuthala kwa Brookfield ndi mazana mpaka masauzande kapenanso masauzande, ndipo kulemera kwa mamolekyu ofanana ndi masauzande mpaka masauzande. Chifukwa cha kuwonjezera kwa ethylene comonomer mu polypropylene copolymer, yomwe imasokoneza dongosolo lokhazikika la mamolekyu a propylene, crystallinity ya polypropylene copolymer ndi yochepa, kotero kuti malo osungunuka amakhalanso otsika.

Pakunyowetsa pigment, kunyowetsa kwa sera kutsika kwambiri kumachitika mwachangu, ndipo kunyowetsa bwino kumakhala kwakukulu. Koma chofunika mu waya extrusion. Mu gawo la granulation, tikuyembekezanso kuti sera ili ndi kukhuthala kwina, komwe kumatha kusamutsa mphamvu yakumeta ubweya pakati pa pigment ndi utomoni wosungunuka, kuti pigment yonyowa igawidwe mofanana mu utomoni usungunuke. Panthawiyi, sera ya polypropylene yokhala ndi malo otsika osungunuka ndi sera ya polypropylene yokhala ndi kukhuthala kwakukulu ingagwiritsidwe ntchito limodzi kuti ikwaniritse kubalalitsidwa kwabwino.
Malingaliro a kampani Qingdao Sainuo Chemical Co.,Ltd. Ndife opanga sera PE, PP sera, OPE sera, Eva sera, PEMA, EBS, Zinc / Calcium Stearate…. Zogulitsa zathu zadutsa REACH, ROHS, PAHS, FDA kuyesa.
