Polypropylene yog cov khoom siv hluavtaws ua los ntawm polymerization ntawm propylene (CH3-CH = CH2) nrog H2 raws li qhov hnyav molecular hloov.Muaj peb stereomers ntawm PP - isotactic, atactic thiab syndiotactic.PP tsis muaj pawg polar thiab muaj cov khoom siv hluav taws xob zoo heev.Nws qhov nqus dej tsawg dua 0.01%.PP yog ib tug semi-crystalline polymer nrog zoo tshuaj stability.Nws ruaj khov rau feem ntau cov tshuaj tshwj tsis yog muaj zog oxidizers.Inorganic acid, alkali thiab ntsev daws yuav luag tsis muaj kev puas tsuaj rau PP.PP muaj cov cua kub zoo thiab tsis tshua muaj siab.Nws melting point yog nyob ib ncig ntawm 165 ℃.Nws muaj lub zog tensile siab thiab nto hardness thiab zoo ib puag ncig kev nyuaj siab tawg kuj.Nws tuaj yeem tiv taus 120 ℃ tsis tu ncua.
Sinopec yog tus tsim khoom loj tshaj plaws PP hauv Suav teb, Nws lub peev xwm PP suav txog 45% ntawm tag nrho lub tebchaws.Lub tuam txhab tam sim no muaj 29 PP cov nroj tsuag los ntawm cov txheej txheem txuas ntxiv (suav nrog cov uas tab tom tsim kho).Cov thev naus laus zis siv los ntawm cov chav no suav nrog Mitsui Chemical's HYPOL txheej txheem, Amoco's roj theem txheej txheem, Basell's Spheripol thiab Spherizone txheej txheem thiab Novolen's roj theem txheej txheem.Nrog nws lub peev xwm tshawb fawb muaj zog, Sinopec tau tsim nws tus kheej tsim lub voj voog thib ob rau PP ntau lawm.
PP nta
1.Cov txheeb ze ntom ntom yog me me, tsuas yog 0.89-0.91, uas yog ib qho ntawm cov khoom siv sib xws hauv cov yas.
2.zoo txhua yam khoom, ntxiv rau qhov cuam tshuam tsis kam, lwm yam khoom siv kho tshuab zoo dua li polyethylene, molding kev ua tau zoo.
3.Nws muaj kev kub ntxhov siab thiab kev siv tas li tuaj yeem ncav cuag 110-120 ° C.
4. Cov khoom siv tshuaj zoo, yuav luag tsis muaj dej nqus, thiab tsis hnov mob nrog cov tshuaj feem ntau.
5.Qhov kev ntxhib los mos yog ntshiab, tsis muaj tshuaj lom.
6. hluav taws xob rwb thaiv tsev zoo.

Hauv 25kg hnab, 16MT hauv ib lub 20fcl tsis muaj pallet lossis 26-28MT hauv ib lub 40HQ tsis muaj pallet lossis 700kg jumbo hnab, 26-28MT hauv ib lub 40HQ tsis muaj pallet.
Polypropylene yog non-toxic, tsw, tasteless milky dawb siab crystallization polymer, yog ib tug ntawm cov lightest ntau yam ntawm tag nrho cov plastics tam sim no, zoo formability, cov khoom nto luster, tshav kub tsis kam, corrosion kuj, cov khoom muaj chav tshuaj tua kab mob yog qhov zoo tshaj plaws ntawm polypropylene. .
Lub ntsiab raw khoom ntawm polypropylene yog propylene, uas yog tsim los ntawm naphtha, methanol thiab propane.
Raws li kev txheeb cais, los ntawm qhov kawg ntawm 2018, muaj ntau tshaj 160 propylene ntau lawm tuam txhab nyob rau hauv Tuam Tshoj, nrog rau ib xyoos twg muaj peev xwm ntawm 32.3 lab tons thiab txhua xyoo tso zis ntawm txog 27.1 lab tons, ib xyoo-rau-xyoo kev loj hlob ntawm txog 2.26. %.
Tus nqi ntawm propylene yog cuam tshuam tsis tsuas yog los ntawm tus nqi ntawm cov roj crude, methanol, propane, tab sis kuj los ntawm kev lag luam khoom thiab kev sib raug zoo.
Cov khoom siv tshuaj lom neeg no tau siv dav hauv cov ntaub yas, ntim khoom, tsheb,kho mob, optical fiber ntau cablethiab lwm yam kev lag luam, hauv kev tsim kho tshiab, kev kho dua tshiab, yuav muaj cov kev cai tshiab.
Nrog rau kev txhim kho tas mus li ntawm peb txoj kev lag luam, kev lag luam yas ua lag luam nthuav tawm cov kev xav tau tshiab ntawm "functionalization", "lub teeb" thiab "micro-molding", uas ua rau muaj kev loj hlob ruaj khov ntawm kev thov rau nyias-phab ntsa txhaj molding, muaj feem cuam tshuam copolymerization. , fiber ntau thiab lwm yam khoom siv polypropylene.
