PVC daim kab xev hluav taws xob yog cov nplaum nplaum siv dav hauv kev lag luam hluav taws xob. Nws cov rwb thaiv tsev siab, muaj zog adhesion, thiab tsis kam mus rau qhov kub thiab txias ua rau nws yog ib qho khoom siv tseem ceeb rau cov neeg siv hluav taws xob. Tab sis koj puas tau xav paub dab tsi mus rau hauv kev tsim cov kab xev ntau yam?
Kev tsim cov khoom siv hluav taws xob PVC muaj ob peb kauj ruam, txhua qhov yuav tsum tau ua tib zoo saib xyuas kom ntseeg tau tias cov khoom kawg ua tau raws li cov qauv tsim nyog.
Kauj Ruam 1: Kev Npaj Khoom Raw
Thawj kauj ruam hauv kev tsim cov kab xev hluav taws xob PVC yog kev npaj cov khoom siv raw. PVC (polyvinyl chloride) resin, plasticizers, stabilizers, thiab lwm yam additives yog tov nyob rau hauv ib tug tshwj xeeb piv rau cov PVC compound. Qhov zoo ntawm cov khoom siv raw yuav txiav txim siab qhov zoo ntawm cov khoom kawg.
Kauj Ruam 2: Extrusion
Thaum lub PVC compound tau npaj, nws yog extruded los ntawm ib lub tshuab uas melts lub compound thiab shapes nws mus rau hauv ib tug ca strip, uas yog ces txias thiab mob rau ib tug spool. Cov txheej txheem no hu ua calendering.
Kauj Ruam 3: Luam Ntawv
Yog tias daim kab xev yuav tsum muaj cov qauv lossis lub logo, nws yuav tsum tau luam tawm rau hauv cov yeeb yaj kiab extruded siv lub tshuab luam ntawv tshwj xeeb. Cov cwj mem siv yuav tsum yog cov khoom zoo thiab yuav tsum tsis txhob smudge lossis ploj mus dhau sijhawm.
Kauj Ruam 4: Adhesive Txheej
Tom qab luam ntawv, PVC zaj duab xis yog coated nrog ib tug nplaum. Cov nplaum yog thov sib npaug rau ib sab ntawm zaj duab xis siv lub tshuab tshwj xeeb txheej. Cov nplaum siv yuav tsum muaj zog txaus los tuav nws tuav txawm nyob rau hauv huab cua.
Kauj Ruam 5: Slitting
Cov kauj ruam kawg hauv kev tsim khoom yog slitting. Cov spools ntawm PVC zaj duab xis nrog cov nplaum txheej yog txiav rau hauv yob ntawm qhov xav tau dav siv lub tshuab slitting. Cov yob yog tom qab ntawd ntim thiab npaj rau kev xa khoom.
Zuag qhia tag nrho, kev tsim khoom ntawm PVC hluav taws xob daim kab xev yuav tsum muaj kev ua haujlwm siab thiab ua tib zoo saib xyuas kom meej tias cov khoom kawg ua tau raws li cov qauv tsim nyog. Nrog rau cov ntaub ntawv raw khoom zoo, cov txheej txheem tsim khoom, thiab kev ntsuas kev tswj xyuas zoo, PVC daim kab xev hluav taws xob tuaj yeem tsim los muab kev ua haujlwm ntev, txhim khu kev qha, thiab muaj kev nyab xeeb rau kev siv hluav taws xob.
