Mapulogalamu
(ningbo) Taiwan Formosa Plastics pp5090t ntchito zazikulu:
PP ndi zinthu za semi crystalline.Ndizovuta kuposa PE ndipo ili ndi malo osungunuka kwambiri.Popeza mtundu wa homopolymer PP ndi wowonongeka kwambiri pamene kutentha kuli pansi pa 0 ℃, zipangizo zambiri zamalonda za PP zimakhala ndi ma copolymers omwe ali ndi 1-4% ethylene kapena clamp type copolymers okhala ndi ethylene yapamwamba.Mtundu wa PP wa copolymer uli ndi kutentha kwapang'onopang'ono (100 ℃), kuwonekera pang'ono, gloss otsika komanso kukhazikika kochepa, koma kumakhala ndi mphamvu zokulirapo.
Kuthamanga kwa MFR ya PP kumachokera ku 1 mpaka 40. PP yokhala ndi MFR yochepa imakhala ndi mphamvu yotsutsa koma yotsika kwambiri.Kwa zipangizo zomwe zili ndi MFR yomweyo, mphamvu ya mtundu wa copolymer ndi yapamwamba kuposa ya mtundu wa homopolymer.Chifukwa cha crystallization, shrinkage rate ya PP ndiyokwera kwambiri, nthawi zambiri 1.8-2.5%.Ndipo kufanana kwamayendedwe a shrinkage ndikwabwinoko kuposa kwa PE-HD ndi zida zina.Kuonjezera 30% zowonjezera magalasi kungachepetse kuchepa kwa 0.7%.
Mitundu ya homopolymer ndi zida za PP zamtundu wa copolymer zili ndi kukana kwamayamwidwe abwino kwambiri, acid-base corrosion resistance and dissolution resistance.Komabe, ilibe kukana kununkhira kwa hydrocarbon (monga benzene) zosungunulira ndi chlorinated hydrocarbon (carbon tetrachloride) zosungunulira.PP ilibe kukana kwa okosijeni pa kutentha kwakukulu monga PE imachitira.
Malinga ndi zomwe zili pamwambapa, PP ndiyoyenera pazinthu zotsatirazi:
1. Jekeseni: ma valve, zowonjezera, makatesi, magalimoto, zotsekera, zida zamagetsi, mabotolo amadzi, Zotengera chakudya, katundu wapakhomo, zoseweretsa, majakisoni osadzaza.
2. Extrusion: wandiweyani pepala, pepala, chitoliro, udzu, kumanga tepi, pepala pepala, BOPP filimu Mapepala ndi Mzere.
3. Kuwomba akamaumba: botolo.
4. Thermoforming: thireyi, mbale, odzola chikho, madzi chikho.
5. Ulusi wathyathyathya: thumba loluka, thumba la chidebe, kapeti.
