Cov ntaub vinyl tarpaulin ua li cas?

Cov ntaub vinyl tarpaulin, feem ntau hu ua PVC tarpaulin, yog cov khoom siv ruaj khov ua los ntawm polyvinyl chloride (PVC). Cov txheej txheem tsim cov ntaub vinyl tarpaulin muaj ntau kauj ruam nyuaj, txhua kauj ruam pab txhawb rau cov khoom kawg lub zog thiab kev hloov pauv tau yooj yim.

1. Sib tov thiab yajKauj ruam pib hauv kev tsim cov ntaub vinyl tarpaulin yog kev sib xyaw cov PVC resin nrog ntau yam khoom ntxiv, xws li cov plasticizers, stabilizers, thiab pigments. Cov khoom sib xyaw ua tib zoo no ces raug rau qhov kub siab, ua rau muaj cov khoom sib xyaw PVC uas yaj uas ua lub hauv paus rau cov ntaub tarpaulin.
2. Kev rho tawm: Cov khoom sib xyaw PVC uas yaj lawm raug rho tawm los ntawm lub tshuab tuag, uas yog ib lub cuab yeej tshwj xeeb uas ua rau cov khoom siv ua ib daim ntawv tiaj tus, txuas ntxiv mus. Daim ntawv no tom qab ntawd raug txias los ntawm kev hla nws los ntawm ntau lub rollers, uas tsis yog tsuas yog ua kom cov khoom siv txias xwb tab sis kuj ua kom du thiab tiaj tus nws qhov chaw, kom ntseeg tau tias nws sib xws.
3. TxheejTom qab txias lawm, daim ntawv PVC yuav raug txheej txheem hu ua txheej txheej riam hla lub yob. Hauv kauj ruam no, daim ntawv yuav raug hla lub riam uas tig mus los uas siv ib txheej kua PVC rau ntawm nws qhov chaw. Cov txheej txheej no ua rau cov khoom siv tiv thaiv zoo dua thiab ua rau nws ruaj khov.
4. Kev teeb tsa daim ntawv qhia hnubCov ntawv PVC uas tau coated ces raug ua tiav los ntawm cov calendaring rollers, uas siv ob qho tib si siab thiab cua sov. Cov kauj ruam no yog qhov tseem ceeb rau kev tsim kom du thiab sib npaug nto thaum tseem txhim kho cov khoom siv lub zog thiab kev ruaj khov, ua rau nws haum rau ntau yam kev siv.
5. Txiav thiab Ua tiavThaum lub vinyl tarpaulin ua tiav lawm, nws raug txiav kom raws li qhov loj thiab cov duab xav tau siv lub tshuab txiav. Cov npoo ces raug txiav thiab txhawb nqa nrog grommets lossis lwm yam fasteners, muab lub zog ntxiv thiab ua kom ntev.

Xaus lus, kev tsim cov ntaub vinyl tarpaulin yog ib qho txheej txheem ua tib zoo uas suav nrog kev sib tov thiab yaj cov PVC resin nrog cov khoom ntxiv, extruding cov khoom ua daim ntawv, txheej nws nrog cov kua PVC, calendaring kom ruaj khov dua, thiab thaum kawg txiav thiab ua tiav nws. Qhov kawg yog cov khoom siv muaj zog, ruaj khov, thiab ntau yam uas zoo tagnrho rau ntau yam kev siv, los ntawm cov ntaub npog sab nraum zoov mus rau kev siv hauv kev lag luam.
