Puas Yog Tus Muag Khoom Ntawm Cov Ntawv Thoob Ntiaj Teb Zoo Tshaj Tawm?
May 28, 2018
PVC yog PVC, nws yog ib qho khoom loj tshaj plaws hauv lub ntiaj teb, pheej yig, daim ntawv thov dav, polyvinyl chloride (PVC) rein li dawb los yog daj daj hmoov, ib leeg siv tsis tau, yuav tsum muab hloov. PVC yog ib qho dawb amorphous hmoov nrog degree me branched thiab pluag stability rau lub teeb thiab cua sov. Txawv ntxiv additives yuav muab ntxiv raws li kev sib txawv ntawm USES thiab txawv lub cev thiab txhua yam khoom ntawm polyvinyl chloride plastics yuav nthuav tawm. Muaj ntau yam tawv, mos thiab pob tshab khoom siv los ntawm kev ntxiv tus nqi ntawm cov yas yas rau polyvinyl chloride cob.
PVC ua qauv hmoov hmoov. Cov feem ntau ntawm Suav teb yog sg-5, raws li sg-3, sg-7, sg-8, thiab lwm yam. Txhua tus qauv yog nyob ntawm qhov txawv, kev lag luam feem ntau siv viscosity thiab K nqi qhia tau hais tias qhov nruab nrab ntawm molecular PVC (los yog qhov nruab nrab degree ntawm polymerization), namely PVC molecular saw ntev, los txiav txim seb lub hom thiab qhov txawv ntawm rein thiab coj ua tsis. Qhov hnyav ntawm qhov hnyav ntawm lub pob zeb muaj feem xyuam rau cov khoom thiab lub zog khoom ntawm cov khoom.
PVC reag yog ib hom ntawm amorphous linear polymer compound, nws cov txheeb ze molecular loj dua, lub siab dua tus lej viscosity, siab dua qhov phaus molecular ntawm cov tensile zog, feem zog, elastic modulus ntau dua, tab sis cov tawv txhuam liquidity thiab yas. Cov viscosity feem ntau yog siv los sawv cev rau qhov hnyav ntawm molecular ntawm polymer thiab cais cov qauv polymer. Tam sim no cia peb tshawb xyuas cov yam ntxwv ntawm txhua tus qauv:
Thawj tus qauv yog hom 3 PVC. Piv nrog rau hom 5, kev tsim tawm hom 3 PVC yuav tsum tau ntev lub sij hawm ntev, siab polymerization kub, siab yuav tsum tau ntxiv rau cov ntaub ntawv pab ntxiv, thiab cov nqi ntau yog 50-100 yuan / ton siab tshaj ntawm hom 5. 3 hom PVC dua purity, tsawg fisheye, blister yooj yim, kub kub, rwb thaiv tsev thiab khoom zoo ntawm ib cov khoom muag, tsuas yog rau cov khoom muag mos thiab cable, ua liaj ua teb, cov khoom siv yas, txhua hnub yas khoom, thiab lwm yam.
Qhov thib ob yog sg-7 / sg-8 thiab sg-5 PVC. No peb cov resins tau tsim nyob rau hauv tib txoj kev thiab cov khoom siv los tsim yog raws nraim tib yam. Lub ntsiab qhov sib txawv yog nyob rau hauv lub cev ntawm cov additives, qhov tshuaj tiv thaiv polymerization kub, qhov fab kev siab thiab lwm yam.
Los ntawm cov ntsiab lus ntawm cov tshuaj tiv thaiv kub thiab fab. SG - 8 pob tau ua tiav qhov kev ua haujlwm siab ntawm kev ua haujlwm ntawm polymerizer, kev ua haujlwm tsis txaus siab, kev lag luam, kev ruaj ntseg, kev siv technology thiab cov neeg ua haujlwm, thiab lwm yam, ntau nruj, thiab zoo dua qhov nyuaj tswj.
Nyob rau hauv cov nqe lus ntawm cov khoom zoo. Qhov sib txawv ntawm SG-8 thiab SG-7 resins yog viscosity, lwm indexes tsis sib txawv, thiab qhov raug ntawm SG-7 resins ntau dua li ntawm cov SG-7 resins. Cov nqi sg-8 rov sg-7 yog tus nqi tib yam li cov sg-7 reintegration, uas yog me ntsis siab tshaj li ntawm sg-7. Feem ntau cov lag luam hais tias sg-8 cov nqi yog me ntsis siab dua sg 5, tab sis cov nqi sib txawv ntawm cov tuam txhab txawv me ntsis txawv. Tus nqi ntawm lub sg-8 yog me ntsis siab tshaj qhov ntawm sg-5 qauv 100-150, raws li cov tuam txhab uas xav tau hloov mus rau lwm cov qauv
Tus nqi SG-8 tsis txawv ntawm SG-5.
PVC muaj ntau hom kev siv thiab txawv cov qauv siv los ntawm kev cai sib txawv. Piv txwv li: SG5 (K - 65, S1000) siv rau, thiab rau tubing, molding, phaj thiab SG3, S1300 (K - 70) yog muag cov khoom muag uas siv los ua ntau cov hose, xaim thiab cable, zaj duab xis, nkawm khau , cov khoom ua si, pib qhov khoom. SG7, SG8 (k-60, S800, S700) feem ntau yog siv rau cov yeeb nkab fittings, ntawv cov ntaub ntawv, ntim, thiab lwm yam. Nyob hauv txojcai, ntau dua cov qauv, qhov nyuab qhov khoom.
