Xyoo 1928 hauv St. Paul, Minnesota, Richard Drew tau tsim Scotch daim kab xev. Daim kab xev tuaj yeem muab faib ua daim kab xev kub, ob-sided daim kab xev, insulating daim kab xev, daim kab xev tshwj xeeb, daim kab xev siab, thiab daim kab xev tuag raws li nws txoj haujlwm. Cov haujlwm sib txawv yog tsim rau kev lag luam sib txawv. Qhov saum npoo ntawm daim kab xev yog coated nrog ib txheej ntawm cov nplaum ua kom daim kab xev lo rau qhov khoom. Cov adhesives ntxov tshaj plaws yog los ntawm cov tsiaj thiab nroj tsuag. Nyob rau hauv lub xyoo pua puv 19, roj hmab yog cov khoom tseem ceeb ntawm cov nplaum; Niaj hnub no, ntau yam polymers tau siv dav.
1. Lub hauv paus ntsiab lus ntawm kev siv daim kab xev
Adhesive daim kab xev yog tsim los ntawm ob qhov chaw: substrate thiab nplaum, uas txuas ob los yog ntau tshaj disjoint khoom los ntawm kev sib txuas. Nws nto yog coated nrog ib txheej ntawm cov nplaum. Cov adhesives ntxov tshaj plaws yog los ntawm cov tsiaj thiab nroj tsuag. Nyob rau hauv lub xyoo pua puv 19, roj hmab yog cov khoom tseem ceeb ntawm cov nplaum; Niaj hnub no, ntau yam polymers tau siv dav. Adhesives tuaj yeem lo rau cov khoom vim tias lawv cov molecules tsim cov ntawv cog lus nrog cov molecules ntawm cov khoom sib txuas, thiab daim ntawv cog lus no tuaj yeem khi cov molecules ua ke. Cov muaj pes tsawg leeg ntawm cov nplaum, raws li cov npe sib txawv, thiab ntau hom, muaj ntau yam polymers.
2. Kev faib tawm ntawm daim kab xev
Cov khoom siv hauv paus: tuaj yeem muab faib ua BOPP daim kab xev, daim kab xev, kraft daim kab xev, daim kab xev npog, fiber ntau daim kab xev, PVC daim kab xev, PE npuas daim kab xev, thiab lwm yam.
Raws li cov peev txheej ntawm daim ntawv thov: nws tuaj yeem muab faib ua daim kab xev ceeb toom, ntaub pua plag daim kab xev, hluav taws xob daim kab xev, tiv thaiv zaj duab xis ntawv daim kab xev, wrapping zaj duab xis daim kab xev, sealing daim kab xev, module daim kab xev, thiab lwm yam.
Kev lag luam nkag mus rau tus nqi: tuaj yeem muab faib ua daim kab xev zoo tib yam thiab daim kab xev tshwj xeeb.
Raws li daim ntawv thov ib puag ncig qhov kub thiab txias: tuaj yeem muab faib ua daim kab xev uas tsis tshua muaj kub, daim kab xev ntsuas kub ib txwm, thiab daim kab xev kub kub.
Raws li adhesiveness: ib daim kab xev ib sab thiab ob sab daim kab xev.
3. Specification ntawm daim kab xev
(1) Jumbo Roll master yob, uas yog, tus qauv daim kab xev rau thiab tawm ntawm lub tshuab, muaj qhov dav ntawm 1 meter mus rau 1.5 meters, thiab qhov ntev ntawm ob peb puas meters mus rau ob peb kilometers, nyob ntawm qhov sib txawv substrates.
(2) Log Roll yog cov khoom tom qab rewinding ntawm niam txiv yob, qhov dav tsis hloov pauv, thiab qhov ntev nws txawv raws li qhov yuav tsum tau ua (feem ntau 100 meters, 50 meters, 25 meters, 10 meters, 5 meters, thiab lwm yam).
(3) Slit Roll (cov yob tiav) yog cov khoom lag luam nyob rau hauv kev ua lag luam.
