Vinyl tarpaulin, feem ntau hu ua PVC tarpaulin, yog cov khoom siv muaj zog ua los ntawm polyvinyl chloride (PVC). Cov txheej txheem tsim khoom ntawm vinyl tarpaulin suav nrog ntau cov kauj ruam sib txawv, txhua qhov ua rau cov khoom kawg lub zog thiab ntau yam.
1. Sib tov thiab Melting: Thawj kauj ruam hauv kev tsim cov yas tarpaulin suav nrog kev sib txuas ntawm PVC cob nrog ntau yam khoom ntxiv, xws li plasticizers, stabilizers, thiab pigments. Qhov kev sib xyaw ua tib zoo no yog tom qab ntawd raug rau qhov kub thiab txias, uas ua rau lub molten PVC compound uas yog lub hauv paus rau lub tarpaulin.
2. Extrusion: Lub molten PVC compound yog extruded los ntawm ib tug tuag, ib tug tshwj xeeb lub cuab tam uas shapes cov khoom mus rau hauv ib tug ca, nruam daim ntawv. Daim ntawv no yog tom qab txias los ntawm kev hla nws los ntawm kev sib tw, uas tsis tsuas yog txias cov khoom tab sis kuj du thiab flatten nws nto, kom ntseeg tau tias uniformity.
3. Txheej: Tom qab txias, cov ntawv PVC tau dhau los ua txheej txheem txheej txheej hu ua riam-dhau-yob txheej. Nyob rau hauv cov kauj ruam no, daim ntawv yog hla dhau ib tug rotating riam hniav uas siv ib txheej ntawm cov kua PVC rau nws nto. Cov txheej no txhim kho cov khoom tiv thaiv zoo thiab pab txhawb rau nws tag nrho durability.
4. Daim ntawv qhia hnub: Cov ntawv coated PVC yog tom qab ntawd ua tiav los ntawm daim calendaring rollers, uas siv ob qho tib si siab thiab kub. Cov kauj ruam no yog qhov tseem ceeb rau kev tsim kom muaj kev sib tw, txawm tias ntog thaum tseem txhim kho cov khoom siv lub zog thiab ua haujlwm ntev, ua rau nws haum rau ntau yam kev siv.
5.Kev txiav thiab ua tiav: Thaum lub vinyl tarpaulin tau tsim tag nrho, nws raug txiav mus rau qhov xav tau loj thiab cov duab siv lub tshuab txiav. Cov npoo yog ces hemmed thiab ntxiv dag zog nrog grommets lossis lwm yam fasteners, muab lub zog ntxiv thiab ua kom lub neej ntev.
Hauv kev xaus, kev tsim cov yas tarpaulin yog txheej txheem txheej txheem uas suav nrog kev sib xyaw thiab melting PVC resin nrog cov khoom siv ntxiv, extruding cov ntaub ntawv rau hauv cov ntawv, txheej nrog kua PVC, daim ntawv qhia hnub rau kev txhim kho, thiab thaum kawg txiav thiab ua tiav nws. Qhov kawg tshwm sim yog ib qho muaj zog, ruaj khov, thiab ntau yam khoom siv uas zoo tagnrho rau ntau yam kev siv, los ntawm kev siv sab nraum zoov mus rau kev lag luam.
