imikhiqizo

I-PP resin yokupakisha,
ezokwelapha, intambo yefiber optical, I-PP resin esetshenziselwa imoto,

I-Polypropylene i-resin yokwenziwa eyenziwe nge-polymerization ye-propylene (CH3—CH=CH2) ene-H2 njengesishintshi sesisindo samangqamuzana.Kukhona ama-stereomer amathathu e-PP - isotactic, atactic kanye ne-sydiotactic.I-PP ayinawo amaqembu e-polar futhi inezindawo ezinhle kakhulu zokuvala ugesi.Izinga lawo lokumunca amanzi lingaphansi kuka-0.01%.I-PP iyi-polymer e-semi-crystalline enokuqina okuhle kwamakhemikhali.Iqinile kumakhemikhali amaningi ngaphandle kwama-oxidizer aqinile.I-Inorganic acid, i-alkali kanye nezixazululo zikasawoti cishe azinawo umthelela olimazayo ku-PP.I-PP inokumelana nokushisa okuhle kanye nokuminyana okuphansi.Indawo yayo yokuncibilika icishe ibe ngu-165 ℃.Inamandla aphezulu okudonsa kanye nokuqina kobuso kanye nokumelana okuhle nokucindezeleka kwemvelo.Ikwazi ukumelana no-120 ℃ ngokuqhubekayo.

I-Sinopec ingumkhiqizi omkhulu we-PP e-China, amandla ayo e-PP abalelwa ku-45% wenani eliphelele lezwe.Njengamanje inkampani inezitshalo ze-PP ezingama-29 ngenqubo eqhubekayo (kuhlanganise nalezo ezisakhiwa).Ubuchwepheshe obusetshenziswa yilawa mayunithi buhlanganisa inqubo ye-HYPOL ye-Mitsui Chemical, inqubo yesigaba segesi ye-Amoco, inqubo ye-Basell's Spheripol and Spherizone kanye nenqubo yesigaba segesi sikaNovolen.Ngamandla ayo okucwaninga kwesayensi aqinile, i-Sinopec isungule ngokuzimela i-loopprocess yesizukulwane sesibili yokukhiqizwa kwe-PP.

Izici ze-PP

1.Ukuminyana okuhlobene kuncane, kuphela 0.89-0.91, okungenye yezinhlobo ezilula kakhulu kumapulasitiki.

I-2.izakhiwo ezinhle zemishini, ngaphezu kokumelana nomthelela, ezinye izakhiwo zemishini zingcono kune-polyethylene, ukusebenza kokucubungula ukubumba kuhle.

3.Inokumelana nokushisa okuphezulu futhi izinga lokushisa lokusetshenziswa okuqhubekayo lingafinyelela ku-110-120 °C.

4.izakhiwo zamakhemikhali ezinhle, cishe awekho ukumuncwa kwamanzi, futhi awasabeli kumakhemikhali amaningi.

5.ukuthungwa kumsulwa, akunabuthi.

6.electrical insulation muhle.

Ireferensi evame ukusetshenziswa ebangeni le-PP

Isicelo

Iphakheji

Esikhwameni esingu-25kg, 16MT ku-20fcl eyodwa ngaphandle kwepallet noma 26-28MT ku-40HQ eyodwa ngaphandle kwepallet noma i-700kg jumbo bag, 26-28MT ku-40HQ eyodwa ngaphandle kwepallet.

I-Polypropylene ayinabuthi, ayinaphunga, ayinambitheki i-milky white high crystallization polymer, ingenye yezinhlobo ezilula kakhulu kuwo wonke amapulasitiki okwamanje, ukuhleleka okuhle, imikhiqizo ecwebezelayo, ukumelana nokushisa, ukumelana nokugqwala, imikhiqizo etholakalayo yokukhishwa kwe-steam yizinzuzo ezivelele ze-polypropylene. .

Impahla eyinhloko ye-polypropylene yi-propylene, eyenziwa ngokuyinhloko nge-naphtha, i-methanol ne-propane.

Ngokwezibalo, ngasekupheleni kuka-2018, kwase kunamabhizinisi angaphezu kuka-160 okukhiqiza i-propylene e-China, enamandla okukhiqiza ngonyaka angaba amathani ayizigidi ezingu-32.3 kanye nokukhishwa konyaka okungamathani ayizigidi ezingu-27.1, ukukhula konyaka ngonyaka okungaba ngu-2.26 %.

Intengo ye-propylene ayithinteki kuphela ngentengo kawoyela ongahluziwe, i-methanol, i-propane, kodwa futhi nobudlelwano bokuhlinzekwa kwemakethe kanye nesidingo.

Lolu hlobo lwamakhemikhali asetshenziswa kabanzi ekwalukeni kwepulasitiki, ukupakisha, imoto,ezokwelapha, intambo yefiber opticalkanye neminye imikhakha, ekuthuthukisweni kwezimboni ezintsha, ukuthuthukiswa, kuzoba nezidingo ezintsha.

Ngokuthuthuka okuqhubekayo komnotho wethu, imboni yokucubungula ipulasitiki yethula inkambiso entsha yesidingo "yokusebenza", "i-lightweight" kanye "ne-micro-molding", eqhuba ukukhula okuzinzile kwesidingo sokubunjwa komjovo odongeni oluncane, i-copolymerization yomthelela omkhulu. , i-fiber neminye imikhiqizo ye-polypropylene.
