Malangizo apakati: PP imatha kugawidwa molingana ndi magawo osiyanasiyana, m'gululi imatha kukhala yosiyana siyana yosungunuka, komanso malingana ndi kugwiritsa ntchito zowonjezera pazinthu zamtundu uliwonse kuti mudziwe momwe mungagwiritsire ntchito mafotokozedwe. MFR: 12 kapena kupitilira apo angagwiritsidwe ntchito wambajekeseni mankhwala, Ingagwiritsidwenso ntchito popanga ulusi wa multifilament, ndipo ikhoza kupangidwa mwapadera kuti ipereke kugawa kwakukulu kwa maselo kuti apititse patsogolo gawo lakumbuyo la fiber weaving. kuonjezera kutsegula kuti akwaniritse zofunikira zathumba la pulasitikimankhwala.
1. Mulingo wamba (Homopolymer)
Monopolymer, kapena homopolymer, ndi zopangira zomwe propylene yoyera imapangidwa ndi polymerized.
2. Impact COPOLYMER
Pamene polima imodzi imawonjezeredwa ndi mphira wa ethylene propylene, mphamvu yowonongeka makamaka imadalira mphira, ndipo kukana kuzizira kumadalira makamaka zomwe zili ndi ethylene.
3. Ma isotacites apamwamba kapena CHRISTALLINITY YABWINO
Kuchepetsa zili dislocation dongosolo PP polima, kuchuluka wachibale wa zinthu zonse kapangidwe, komanso kusintha crystallinity.It makamaka bwino rigidity, matenthedwe denaturation kutentha, pamwamba kuuma, zikande kukana ndi gloss wa zipangizo. nucleating agent idzathandiziranso kupititsa patsogolo zinthu zomwe zili pamwambazi.
4. COPOLYMER mwachisawawa
Randomized copolymerization ndi propylene ndi ethylene copolymerization.Ethylene amamwazikana mosiyanasiyana mu polima, amene makamaka amachepetsa crystallinity wa polima ndi bwino mandala.
5. Terpolymer
Ndi kukulitsa kwachisawawa kwa polima, nthawi zambiri kumakhala ndi propylene ethylene (EPR) yokwera kwambiri pa 3.5%, koma palinso njira yomwe ingawonjezedwe ku 5%, komanso kuchuluka kwa ethylene muzinthu zofewa, kutentha kutentha, kufewetsa. mfundo, m'munsi kutentha kusindikiza kutentha, nthawi zina pofuna kuonjezera ethylene okhutira ndi thandizo la butadiene kapena zosakaniza lachitatu kukhala atatu wamba polima, kuti tikwaniritse pamwamba thupi zofunika katundu.
6. Aloyi kalasi
Kusakaniza kwa zipangizo zosiyanasiyana za pulasitiki zokhala ndi gawo lalikulu lingathe kufotokozedwa ngati kalasi ya alloy.Mwachitsanzo, PP yowonjezeredwa ndi LDPE ikhoza kupititsa patsogolo kufewa ndi mphamvu yamphamvu, komanso kuchepetsa khosi ndikuwonjezera kutsekemera pokonza.Popanga, imathanso kuchepetsa kutsika kwa zinthu.PP kuphatikiza EPR kuphatikiza HDPE imatha kukhala yolimba, kuchepetsa kuyera komwe kumachitika chifukwa cha kuchuluka kwa EPR, ndikuwongolera mphamvu zake.
7.Kuphatikiza
Kusakaniza kwa zipangizo zosiyanasiyana
