Izinhlelo zokusebenza
(ningbo) Ukusetshenziswa okuyinhloko kwe-Taiwan Formosa Plastics pp5090t:
I-PP iyingxenye ye-semicrystalline material.Iqinile kune-PE futhi inephuzu lokuncibilika eliphakeme.Njengoba uhlobo lwe-homopolymer PP luntekenteke kakhulu uma izinga lokushisa lingaphansi kuka-0 ℃, izinto eziningi ze-PP zokuhweba zingama-copolymer angahleliwe ane-ethylene engu-1-4% noma ama-copolymer ohlobo lwe-clamp anokuqukethwe okuphezulu kwe-ethylene.Into ye-copolymer yohlobo lwe-PP inezinga lokushisa eliphansi lokuhlanekezela okushisayo (100 ℃), ukukhanya okuphansi, ukucwebezela okuphansi kanye nokuqina okuphansi, kodwa inamandla omthelela aqinile.
Izinga lokugeleza kwe-MFR ye-PP lisukela ku-1 kuye ku-40. I-PP ene-MFR ephansi inokumelana nomthelela ongcono kodwa amandla okubamba aphansi.Okwezinto zokwakha ezine-MFR efanayo, amandla ohlobo lwe-copolymer aphakeme kunalawo ohlobo lwe-homopolymer.Ngenxa ye-crystallization, izinga lokuncipha kwe-PP liphezulu kakhulu, ngokuvamile li-1.8-2.5%.Futhi ukufana kokuqondisa kokuncipha kungcono kakhulu kunokwe-PE-HD nezinye izinto.Ukwengeza okungeziwe okungu-30% kwengilazi kunganciphisa ukushwabana kube ngu-0.7%.
Uhlobo lwe-homopolymer kanye nohlobo lwe-copolymer PP izinto zinokumelana okuhle kakhulu kokumuncwa komswakama, ukumelana nokugqwala kwe-acid-base kanye nokumelana nokuqedwa.Kodwa-ke, ayinakho ukumelana ne-hydrocarbon enuka kamnandi (njenge-benzene) ne-chlorinated hydrocarbon (carbon tetrachloride) solvent.I-PP ayinakho ukumelana ne-oxidation ekushiseni okuphezulu njengoba i-PE yenza.
Ngokusho kokusebenza okungenhla, i-PP ifanele imikhiqizo elandelayo:
1. Umjovo: amavalvu, izesekeli, amakhreyithi, izimoto, izinto ezivaliwe, izinto zikagesi, amabhodlela amanzi, Iziqukathi zokudla, impahla yasendlini, amathoyizi, imijovo engagcwaliswanga ngaphambili.
2. I-Extrusion: ishidi eliwugqinsi, ishidi, ipayipi, utshani, itheyiphu yokubopha, ishidi lezinto zokubhala, Ishidi lefilimu ye-BOPP kanye nomugqa.
3. Blow ukubumba: ibhodlela.
4. I-Thermoforming: ithreyi, isitsha, inkomishi ye-jelly, inkomishi yamanzi.
5. Intambo eyisicaba: isikhwama esilukiwe, isikhwama sesitsha, ukhaphethi.
