pvc cob k nqi 57,
PVC cob siv los tsim WPC, Raw khoom rau WPC ntau lawm.,
WPC yog ib hom tshiab ntawm cov khoom siv hauv ib puag ncig, uas yog sib xyaw los ntawm cov ntoo thiab yas, nrog kev ntxhib los mos ntawm cov ntoo thiab cov kav ntev ntawm cov yas.Cov txheej txheem tsim khoom ntawm WPC feem ntau suav nrog kev npaj cov khoom siv raw, sib tov, extrusion, txias, txiav thiab ntim.
Kev npaj cov khoom nyoos yog thawj kauj ruam hauv WPC ntau lawm.Cov ntaub ntawv raw ntawm WPC feem ntau suav nrog ntoo hmoov, yas, additives thiab lwm yam.Ntawm lawv, ntoo hmoov yog ua los ntawm ntoo tom qab crushing, tshuaj ntsuam thiab lwm yam txheej txheem, thiab yas yog ua los ntawm polyethylene, polypropylene thiab lwm yam ntaub ntawv raw khoom.Cov khoom siv ntxiv muaj xws li tshuaj tua kab mob, tshuaj tua kab mob antioxidant, pigments, thiab lwm yam, siv los txhim kho kev ua haujlwm thiab kev zoo nkauj ntawm WPC.
Kev sib xyaw yog cov txheej txheem ntawm kev sib xyaw cov hmoov nplej, yas thiab cov khoom ntxiv hauv ib qho kev faib ua feem.Lub hom phiaj ntawm kev sib xyaw yog ua kom muaj ntau yam khoom siv sib xyaw ua ke los ua ib qho kev sib xyaw ua ke, npaj rau cov txheej txheem extrusion tom ntej.
Tom qab ntawd, extrusion yog txheej txheem ntawm squeezing cov ntaub ntawv sib xyaw los ntawm extruder.Lub extruder heats cov khoom sib xyaw ua ke rau ib qho kub kom nws muag, thiab tom qab ntawd extrudes nws los ntawm pwm.Lub extruded ntoo-yas board muaj tej yam zoo li thiab loj, tab sis nws kuj yuav tsum tau txias thiab txiav.
Tom qab ntawd, kev ua kom txias yog cov txheej txheem ntawm kev tso lub extruded WPC rau ntawm qhov chaw txias txias rau lub ntuj txias.Lub hom phiaj ntawm kev ua kom txias yog kom ceev ceev WPC, ua kom nws cov duab thiab qhov loj me ruaj khov, thiab tsis txhob muaj teeb meem xws li deformation thiab tawg.
Txiav thiab ntim khoom yog txheej txheem ntawm kev txiav thiab ntim cov WPC txias.Kev txiav yog txiav cov ntoo-yas board raws li qhov loj me, kom nws ua tau raws li cov neeg siv khoom xav tau.Ntim yog txiav ntoo yas board rau ntim, kom yooj yim rau kev thauj mus los thiab kev muag khoom.
Cov txheej txheem tsim khoom ntawm WPC suav nrog kev npaj raw khoom, sib tov, extrusion, txias, txiav thiab ntim.Cov kev sib txuas no koom tes nrog ib leeg los ua kom tiav cov txheej txheem tsim khoom ntawm WPC, muab cov neeg siv khoom zoo nkauj, zoo nkauj thiab ruaj khov.
Polyvinyl Chloride, hu ua PVC, yog ib qho ntawm cov khoom siv yas yas, cov zis tam sim no tsuas yog thib ob rau polyethylene.Polyvinyl chloride tau siv dav hauv kev lag luam, kev ua liaj ua teb thiab lub neej txhua hnub.Polyvinyl chloride yog ib qho polymer compound polymerized los ntawm vinyl chloride.Nws yog thermoplastic.Dawb los yog lub teeb daj hmoov.Nws yog soluble hauv ketones, esters, tetrahydrofurans thiab chlorinated hydrocarbons.Cov tshuaj tiv thaiv zoo heev.Tsis zoo thermal stability thiab lub teeb tsis kam, ntau tshaj 100 ℃ los yog lub sij hawm ntev raug tshav ntuj pib decompose hydrogen chloride, yas manufacturing yuav tsum tau ntxiv stabilizer.Hluav taws xob rwb thaiv tsev zoo, yuav tsis hlawv.
Qib S-700Feem ntau yog siv los tsim cov ntawv pob tshab, thiab tuaj yeem muab dov rau hauv cov ntawv tsis sib xws thiab ib nrab nruj rau pob, cov khoom siv hauv pem teb, cov zaj duab xis tawv rau hauv ob sab phlu (rau cov khoom qab zib wrapping ntawv lossis luam yeeb ntim zaj duab xis), thiab lwm yam. Nws kuj tuaj yeem raug extruded nyuaj los yog semi-hard zaj duab xis, daim ntawv, los yog irregularly zoo li tus bar rau pob.Los yog nws tuaj yeem raug txhaj tshuaj los ua cov pob qij txha, li qub, cov khoom siv hluav taws xob, cov khoom siv pib thiab cov hlab ntsha.
