Vinyl tarpaulin, feem ntau yog hu ua PVC tarpaulin, yog ib qho khoom siv khov kho ntawm polyvinyl chloride (PVC). Kev tsim khoom lag luam ntawm vinyl tarpaulin muaj ntau cov kauj ruam sib txawv, txhua pab txhawb rau cov khoom kawg thiab versatility.
1.Mixing thiab yaj: Thawj kauj ruam hauv kev tsim cov yas vinyl sarpaulin cuam tshuam nrog ntau yam sib ntxiv, xws li cov yas, stabilizers, thiab pigments. Qhov kev sib xyaw ua tib zoo no yog tom qab ntawd raug rau qhov kub thiab txias, ua rau muaj Molten PVC cov compound uas ua haujlwm ua lub hauv paus rau lub tarpaulin.
2.extrusion: Molten pvc compound tau extruded los ntawm kev tuag, cov cuab yeej tshwj xeeb uas cov khoom siv tshwj xeeb uas cov khoom siv rau hauv ib daim tiaj tus, txuas ntxiv. Daim ntawv no yog tom qab txias los ntawm kev dhau nws los ntawm cov rollers ntawm chais, uas tsis tsuas yog txias cov khoom tab sis kuj du thiab flatten nws nto, kom muaj kev sib dhos.
3.COUND: Tom qab txias, lub pvc daim ntawv undergoes ib coating txheej hu ua rab riam-dhau-yob txheej. Hauv cov kauj ruam no, daim ntawv dhau los dhau ib cov kab sib tov uas siv ib txheej ntawm cov kua ntawm cov kua los PVC rau nws qhov chaw. Qhov txheej no ua kom cov khoom ntiag tug ntawm cov khoom tiv thaiv thiab ua rau nws muaj qhov ua rau muaj kev ruaj ntseg tag nrho.
4.Calendaring: Cov coated PVC daim ntawv yog tom qab ua tiav los ntawm daim ntawv qhia nyiaj, uas siv rau ob leeg siab thiab kub. Cov kauj ruam no yog qhov tseem ceeb heev rau kev tsim ib tug du, txawm tias saum npoo thaum tseem txhim kho cov khoom siv lub zog thiab kav rau ntau yam kev siv.
5.ncutting thiab xov: Thaum lub vinyl tarpaulin tau tsim tag nrho, nws yog txiav rau qhov loj thiab cov duab siv lub tshuab txiav. Cov npoo yog tom qab ntawd hemmed thiab txhawb nrog grommets lossis lwm tus fastenters, muab lub zog ntxiv thiab ua kom muaj zog ntxiv thiab ua kom muaj zog ntxiv.
Hauv kev xaus, kev tsim cov roj vinylarin yog cov txheej txheem meticula uas cuam tshuam nrog cov khoom siv ua kua, muab cov khoom sib xyaw rau cov khoom sib xyaw ua kua, thiab thaum kawg txiav thiab ua tiav nws. Qhov kawg tshwm sim yog qhov muaj zog, ruaj, thiab ntau yam khoom uas yog qhov zoo tagnrho rau ntau cov ntawv thov, los ntawm sab nraum zoov cov ntaub ntawv siv.
