Nga tono
(ningbo) Taiwan Formosa Plastics pp5090t whakamahinga matua:
Ko te PP he mea kiriatairangi.He uaua ake i te PE, he teitei ake te ira whakarewa.I te mea he tino pakarukaru te momo homopolymer PP ina kei raro iho te pāmahana i te 0 ℃, he maha nga rauemi PP arumoni he copolymers matapōkere me te 1-4% te ethylene, te rawhi momo copolymers me te nui ake o te ihirangi ethylene.Ko te momo copolymer PP he iti ake te wera o te waiariki (100 ℃), he iti te marama, he iti te kanapa me te iti o te rigidity, engari he kaha ake te kaha o te paanga.
Ko te rerenga rere MFR o PP mai i te 1 ki te 40. Ko te PP me te iti o te MFR he pai ake te awangawanga o te paanga engari he iti ake te kaha o te kaha.Mo nga taonga me te MFR ano, ko te kaha o te momo copolymer he teitei ake i tera o te momo homopolymer.Nā te whātioatanga, he tino tiketike te tere o te whakaheke o te PP, te tikanga 1.8-2.5%.A ko te riterite o te ahunga o te whakaheke he pai ake i tera o te PE-HD me etahi atu rauemi.Ko te taapiri i te 30% taapiri karaihe ka taea te whakaiti i te whakaheke ki te 0.7%.
Ko te momo Homopolymer me te momo copolymer PP he tino pai te aukati i te makuku, te aukati waikura-waikawa me te aukati whakakore.Heoi, karekau he parenga ki te waiwaro kakara (pēnei i te benzene) whakarewa me te waiwaro maota (carbon tetrachloride) whakarewa.Karekau a PP he parenga waikura i te pāmahana teitei pera i te PE.
E ai ki nga mahi o runga ake nei, he pai te PP mo nga hua e whai ake nei:
1. Werohanga: vaolo, taputapu, pouaka, motopaika, kati, taputapu hiko, ipu wai, ipu kai, taonga whare, taonga takaro, kore i whakakiia nga syringe.
2. Tangohanga: te pepa matotoru, te pepa, te paipa, te kakau witi, te rīpene here, te pepa tuhi, te BOPP kiriata Pepa me te tarai.
3. Whakatangihia: pounamu.
4. Thermoforming: paepae, peihana, tiēre kapu, kapu wai.
5. Miro papatahi: peeke raranga, putea ipu, whariki.
