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.
Lub lim tiam no polypropylene downstream kev xav tau txo qis, cov chaw tsim khoom muaj hnub so, kev tsim kho tag nrho qis dua.Raws li tag nrho, kev lag luam hauv tsev polypropylene downstream (suav nrog cov yas knitting, txhaj tshuaj molding, BOPP, PP non-woven npuag) tag nrho cov kev khiav hauj lwm tus nqi poob los ntawm 14.7% mus rau 36.2%.Tus nqi ntawm cov yas knitting txo los ntawm 9.5% mus rau 34%;Txhaj tshuaj molding tus nqi qis 17% mus rau 32%;BOPP pib poob 2.8% rau 60.1%;Tsis-woven pib poob 29.8% rau 18.5%.
Los ntawm qhov kev xav ntawm qhov xav tau, lub lim tiam no cov yas knitting kev lag luam ua haujlwm tau qis dua li lub lim tiam dhau los, nqis 13% xyoo-rau-xyoo.Thaum kawg ntawm lub xyoo, cov lag luam feem ntau tau nkag mus rau hnub so, qhov kev txiav txim ntawm cov lag luam poob qis, qee cov tuam txhab kev txiav txim siab tsis zoo, kev txaus siab ntawm cov lag luam los ntxiv cov khoom siv raw khoom txo qis, feem ntau zom cov khoom tiav cov khoom muag, tag nrho cov khoom lag luam ntawm lub khw. txias;Nyob rau hauv cov nqe lus ntawm BOPP kev lag luam, kev txiav txim hnub ntawm cov qauv lag luam lub lim tiam no yog 7.89% piv nrog rau lub sijhawm dhau los.Raws li qhov kev thov tag nrho ntawm BOPP tsis zoo li xyoo dhau los, cov dej ntws qis thiab cov tub lag luam nyob rau hnub so ua ntej, thiab tag nrho cov kev lag luam ntawm kev lag luam tau sib zog zuj zus thaum lub caij nplooj ntoos hlav Festival tuaj txog.Feem ntau ntawm cov tuam txhab membrane tau tso cov kev txiav txim ua ntej, thiab feem ntau ntawm cov tuam txhab membrane tau ua haujlwm ib txwm nyob rau theem tam sim no, nrog kev txwv tsis pub ua raws li kev txiav txim tshiab.Kev txhaj tshuaj molding kev lag luam pib poob qis heev, cov chaw tsim khoom muaj hnub so, kev lag luam pib poob pom tseeb;Tsis-woven npuag kev lag luam nyob rau hauv lub lim tiam los pib ib qho kev kho tseem ceeb, lub lim tiam no cov hnub txiav txim piv rau lub lim tiam dhau los -3.5 hnub, downstream kev txiav txim pom ib tug downward trend.PP non-woven npuag kev lag luam tau nkag mus rau hnub so, kev lag luam tshiab kev lag luam me me heev.Feem ntau, cuam tshuam los ntawm Lub Caij Nplooj Ntoos Hlav Caij Nplooj Ntoos Hlav, tag nrho cov kev tsim kho qis qis poob qis, ua ntej hnub so txhawb nqa los ntawm yav tom ntej, kev ua haujlwm tau zoo dua qub, txhawb kev lag luam polypropylene kuj muaj zog.
Nyob rau lub sijhawm ntev, polypropylene muab khoom thiab xav tau kev ua si tseem ceeb tseem pom tseeb.Tom qab hnub so, muaj kev cia siab ntawm kev khaws cia hauv khw.Tsis tas li ntawd, nyob rau hauv txoj kev npaj ntawm cov peev txheej tshiab, Guangdong Petrochemical yuav tsum tso tawm cov ntaub ntawv thaum lub caij so, thiab kev ua lag luam siab nce siab.Nyob rau hauv cov nqe lus ntawm kev thov, lub downstream resumption lub sij hawm tom qab lub hnub caiv yog lub ntsiab kev txhawj xeeb ntawm lub khw.Nws tau pom zoo tias cov neeg ua haujlwm ua tib zoo saib xyuas lub sijhawm ua haujlwm rov pib dua.
