imikhiqizo

i-polypropylene yendwangu engalukiwe,
I-PP Resin, I-PP resin yemboni ye-BOPP, I-PP resin yemboni yokubumba i-Injection,

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.

Kuleli sonto inhloso yokuthenga i-polypropylene downstream yehlile, izimboni zinamaholide, ukwakhiwa sekukonke kuphansi kakhulu.Sekukonke, imboni yasekhaya ye-polypropylene ezansi nomfula (okuhlanganisa ukunitha kwepulasitiki, ukubumba umjovo, i-BOPP, indwangu engalukiwe ye-PP) izinga lokusebenza lilonke lehle ngo-14.7% laya ku-36.2%.Izinga lokunitha kwepulasitiki lehle ngo-9.5% laya ku-34%;Izinga lokubumba lomjovo lehle ngo-17% kuya ku-32%;Ukuqala kwe-BOPP kwehle ngo-2.8% kuya ku-60.1%;Ukuqala okungalukiwe kwehle ngo-29.8% kuya ku-18.5%.

Ngokombono wohlangothi lwesidingo, izinga lokusebenza kwebhizinisi lokuluka ipulasitiki kuleli sonto liphansi kakhulu kunesonto eledlule, lehle ngo-13% unyaka nonyaka.Ekupheleni konyaka, amabhizinisi amaningi angenile kuleli holide, isimo sokuhleleka kwamabhizinisi sehle kakhulu, amanye amabhizinisi ayadabula, umdlandla wamabhizinisi wokugcwalisa izinto ezingavuthiwe wehla, ikakhulukazi ukugaya umkhiqizo oqediwe, isimo sokuhweba jikelele semakethe. kwabanda;Ngomkhakha we-BOPP, izinsuku zoku-oda zesampula zamabhizinisi kuleli sonto zingama-7.89% uma ziqhathaniswa nesikhathi esedlule.Njengoba isidingo sisonke se-BOPP singesihle njengaseminyakeni edlule, ezansi nomfula nabahwebi baseholidini kusenesikhathi, futhi isimo sokuhweba jikelele semakethe siya siba lula njengoba uMkhosi Wasentwasahlobo usondela.Iningi lezinkampani ze-membrane zifake ama-oda kusenesikhathi, futhi iningi lamabhizinisi ama-membrane asebenza ngokujwayelekile kulesi sigaba samanje, ngokulandelwa okulinganiselwe kwama-oda amasha.Imboni yokubumba imijovo iqala ukwehla kakhulu, izimboni zinamaholide, imboni iqala ukwehla ngokusobala;Imboni yendwangu engalukiwe phakathi nesonto ukuze iqale ukulungisa okubalulekile, izinsuku zoku-oda zaleli sonto uma ziqhathaniswa neviki eledlule -izinsuku ezingu-3.5, ama-oda awela phansi abonise ukwehla.Izinkampani ze-PP ezingezona ezilukiwe zingene eholidini, ukuthengiselana kwebhizinisi okusha kuncane kakhulu.Ngokuvamile, okuthonywe iholide Lomkhosi Wasentwasahlobo, ukwakhiwa komfula jikelele kwehle kakhulu, ngaphambi kokuba iholide lithuthukiswe yikusasa, ukusebenza kwesitoko kwaba ngcono, okusekela imakethe ye-polypropylene eqinile ngokuqhathaniswa.

Ngokuhamba kwesikhathi, ukuhlinzekwa kwe-polypropylene kanye nesidingo somdlalo oyisisekelo kusasobala.Ngemuva kweholide, kukhona okulindelekile kokuqoqwa kwempahla emakethe.Ngaphezu kwalokho, ohlelweni lwamandla amasha okukhiqiza, i-Guangdong Petrochemical kulindeleke ukuthi ikhulule izinto ngesikhathi samaholide, futhi ingcindezi yokuhlinzekwa kwemakethe ikhuphuka kakhulu.Ngokuya ngesidingo, ishejuli yokuqalisa kabusha umsebenzi engezansi komfula ngemva kweholide iyona nto ekhathaza kakhulu imakethe.Kuphakanyiswa ukuthi opharetha banake kakhulu ishejuli yokuqalisa kabusha umsebenzi.
