imikhiqizo

Synthetic Rope raw material-Polypropylene,
Polypropylene for Plastic Rope, Ukukhiqizwa kwentambo impahla eluhlaza,

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

I-Polypropylene cishe iyinto evamile kakhulu etholakala ezintanjeni ezisetshenziswa endaweni yasolwandle.Esinye isizathu siwukuthi ilula kunamanzi, futhi ngaleyo ndlela iyantanta.
Intambo yePlastiki yePolypropylene yaziwa nangokuthi “Intambo yePolypropene” noma “iRope yePlastiki yePP”.Yakhiwe yilokhu okulandelayo: I-Monomer Propylene kanye ne-polymerization yokukhula okuyi-polymer ye-thermoplastic, eqinile futhi eqinile esetshenziswa ezintweni ezihlukahlukene.Ifomula yamakhemikhali yePolypropylene ithi (C3H6)n.
