imikhiqizo

Imiphi imikhiqizo eyenziwe nge-PP?,
I-PP ye-Caps nokuvalwa, PP resin for Artificial utshani, I-PP resin ye-Food Packaging,

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-PP isetshenziselwa ukwenza uxhaxha lwemikhiqizo yepulasitiki esetshenziswa emphakathini, okuhlanganisa:

Ukupakishwa Komkhiqizo Wabathengi
Ukupakisha Ukudla
Imicu
Imikhiqizo yezimoto
Utshani bokwenziwa
Ofeleba kanye Nokuvalwa
Imikhiqizo Yokunakekela Umuntu
Ibhande lezimboni
