imikhiqizo

I-PP resin ye-PP orientation elula i-polypropylen,
I-polypropylene resin ukukhiqiza ifilimu ye-OPP,

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

Ngokuhlukahluka okuhlukile kwe-100 Ifilimu yePolypropylene ingelinye lamafilimu asetshenziswa kakhulu emhlabeni.Isicelo esivamile se-polypropylene yi-oriented polypropylene (OPP).Le filimu inezici ezinhle kakhulu zokufaka umswakama okwenza lokhu kube kuhle kakhulu ekusebenziseni oyinki abavamile okukhiqiza umphumela wokuphrinta ocacile kakhulu.Namuhla kuyifilimu yokupakisha eguquguqukayo ehamba phambili yesibili kuphela kune-polyethylene ephansi ngevolumu.

(OPP) Ifilimu Ye-Polypropylene Eqondiswe
I-polymer ye-thermoplastic esetshenziswa ezinhlelweni ezahlukahlukene kusukela ekupakishweni, kuya kumakhaphethi.Ukusetshenziswa okuyinhloko kwefilimu ye-OPP kusekuhlanganisweni kokudla ngenxa yamandla amahle, ukucaca okuphezulu, izakhiwo ezivimbelayo ezanele kanye nezindleko eziphansi uma kuqhathaniswa ne-cellophane.Cishe kuyo yonke ingxenye yokuphila kwakho kwansuku zonke.I-Polypropylene imelana kakhulu nokukhathala.Ngakho-ke ihinge yohlobo lwepulasitiki ingavulwa futhi ivalwe izikhathi eziyi-1000 ngaphandle kokukhathala.Iningi lokupakishwa kwe-flip-top linalokhu.Inqubo yokuncibilika kwe-polypropylene itholakala nge-extrusion nokubunjwa.Indlela ejwayelekile yokubumba esetshenziswayo ukubumba umjovo.Amanye amasu ukubumba i-blow kanye ne-injection stretch blow blow molding.Ngokuba nekhono lokuhlanganisa amamaki athile ngezakhiwo ezithile zamangqamuzana ngesikhathi sokukhiqiza kwenza inani elikhulu lezicelo zokusetshenziswa kokugcina.Isibonelo salokhu kungaba ukusetshenziswa kwesithasiselo se-antistatic ukusiza ingaphezulu le-polypropylene ukumelana nokungcola nothuli.
