Nqe lus piav qhia:
Polyvinyl chloride, abbreviated li PVC S1000, yog ib tug polymer tsim los ntawm lub polymerization ntawm vinyl chloride monomer (VCM) nyob rau hauv qhov kev txiav txim.
ntawm peroxides, azo tebchaw thiab lwm yam pib los yog nyob rau hauv qhov kev txiav txim ntawm lub teeb thiab kub raws li dawb radical polymerization cov tshuaj tiv thaiv mechanism.Vinyl chloride homopolymer thiab vinyl chloride copolymer yog sib sau ua ke hu ua vinyl chloride Resin .PVC yog cov hmoov dawb nrog cov qauv amorphous nrog me me ntawm cov ceg.Nws cov iav hloov pauv kub yog 77 ~ 90 ℃, thiab nws pib decompose nyob ib ncig ntawm 170 ℃.Nws muaj kev ruaj ntseg tsis zoo rau lub teeb thiab cua sov.Decomposition tsim hydrogen chloride, uas yog ntxiv autocatalyzed thiab decomposed, ua rau discoloration, thiab lub cev thiab mechanical.
cov khoom kuj poob sai heev.Hauv kev siv cov tswv yim, stabilizers yuav tsum tau ntxiv los txhim kho kev ruaj ntseg rau cov cua sov thiab lub teeb.
PVC S1000 Feem ntau siv rau:
1. PVC profile
Profiles yog thaj chaw loj tshaj plaws ntawm PVC noj hauv kuv lub teb chaws, suav txog li 25% ntawm tag nrho cov khoom siv PVC.Lawv feem ntau yog siv los ua lub qhov rooj thiab qhov rais thiab cov ntaub ntawv txuag hluav taws xob, thiab lawv cov ntawv thov ntim tseem nce ntxiv thoob plaws lub tebchaws.Hauv cov teb chaws tsim, kev lag luam feem ntau ntawm cov qhov rooj yas thiab qhov rais kuj yog qhov siab tshaj plaws, piv txwv li, Lub teb chaws Yelemees yog 50%, Fabkis yog 56%, thiab Tebchaws Meskas yog 45%.
2. Polyvinyl chloride yeeb nkab
Ntawm ntau cov khoom siv polyvinyl chloride, polyvinyl chloride kav yog nws qhov thib ob loj tshaj plaws noj cheeb tsam, suav txog li 20% ntawm nws cov kev siv.Nyob rau hauv kuv lub teb chaws, polyvinyl chloride kav yog tsim ua ntej tshaj PE kav thiab PP kav, nrog ntau ntau yam, kev ua tau zoo heev, thiab ntau yam kev siv, thiab tuav txoj haujlwm tseem ceeb hauv kev ua lag luam.
3. Polyvinyl chloride zaj duab xis
Kev noj ntawm PVC hauv thaj tsam ntawm PVC zaj duab xis yog thib peb, suav txog li 10%.Tom qab PVC yog tov nrog additives thiab plasticized, ib tug peb-yob los yog plaub-yob calender yog siv los ua ib tug pob tshab los yog xim zaj duab xis nrog ib tug tshwj xeeb thickness.Cov yeeb yaj kiab tau ua tiav hauv txoj kev no los ua ib zaj duab xis calendered.Nws tseem tuaj yeem raug txiav thiab kub-sau los ua cov hnab ntim khoom, raincoats, tablecloths, curtains, inflatable cov khoom ua si, thiab lwm yam. Lub dav pob tshab zaj duab xis yuav siv tau rau greenhouses, yas greenhouses thiab mulch films.Lub biaxially stretched zaj duab xis muaj cov yam ntxwv ntawm tshav kub shrinkage thiab yuav siv tau rau shrink ntim.
4. PVC tawv cov ntaub ntawv thiab daim hlau
Stabilizers, lubricants thiab muab tub lim yog ntxiv rau PVC.Tom qab sib tov, lub extruder tuaj yeem siv los extrude cov kav dej nyuaj, cov kav dej tshwj xeeb thiab cov kav dej corrugated ntawm ntau yam calibers, uas tuaj yeem siv los ua cov kav dej phwj, cov kav dej haus, cov hlau casings lossis staircase handrails.Cov ntawv calendered yog overlapped thiab kub nias. los ua cov phaj tawv ntawm ntau yam thicknesses.Lub phaj tuaj yeem txiav rau hauv cov duab uas yuav tsum tau ua, thiab tom qab ntawd welded nrog cua kub nrog PVC vuam pas nrig los tsim ntau yam tshuaj resistant cia tank, cua ducts thiab ntim.
