Adhesive daim kab xev yog tsim los ntawm cov khoom siv hauv paus thiab cov nplaum, uas txuas ob lossis ntau dua cov khoom tsis sib txuas ua ke los ntawm kev sib txuas. Nws nto yog coated nrog ib txheej ntawm cov nplaum. Cov nplaum thaum ntxov tuaj ntawm cov tsiaj thiab cov nroj tsuag, thiab cov roj hmab yog cov khoom tseem ceeb ntawm cov nplaum; Tam sim no ntau yam polymers tau siv dav.
Adhesives tuaj yeem lo rau tej yam vim yog kev tsim cov ntawv cog lus ntawm lawv tus kheej cov molecules thiab cov molecules ntawm cov khoom sib txuas, thiab daim ntawv cog lus no tuaj yeem khi cov molecules ua ke.
Adhesive daim kab xev yog siv ntau zaus hauv peb lub neej, nws tuaj yeem pom txhua qhov chaw, thiab muaj ntau hom. Yog li dab tsi yuav tsum tau them sai sai rau thaum siv cov nplaum nplaum?
1. Ua ntej siv, qhov chaw ntawm adherend yuav tsum tau ntxuav, thiab impurities xws li roj, dej, thiab plua plav yuav tsum tau muab tshem tawm tag nrho, thiaj li ua kom nws cov nplaum nplaum.
2. Siv ib qho ntawm qhov siab tom qab kev sib txuas ntawm daim kab xev, kom daim kab xev tuaj yeem muab kev ua si tag nrho rau nws cov viscosity thiab khaws cia rau lub sijhawm ntev.
3. Thaum peb muab daim kab xev, qhov kub ntawm qhov chaw sib txuas yog tswj ntawm chav tsev kub, thiab nws yog ib qho tseem ceeb heev los xyuas kom meej qhov kub thiab txias.
4. Ceev faj tsis txhob kov cov dej thaum siv daim kab xev los lo cov khoom. Thaum dej sticks, qhov nplaum ntawm daim kab xev yuav raug puas tsuaj.
5. Tsis txhob rov pasting (tsis li ntawd, cov nplaum nplaum ntawm daim kab xev yuav puas), tom qab pasting, cia nws sawv ntsug ib pliag;
6. Muab tshuaj txhuam ncaj qha rau ntawm tib neeg lub cev, concave-convex thiab ntxhib nto;
7. Thaum khaws daim kab xev, tsis txhob raug tshav ntuj ncaj qha thiab qhov chaw tshav kub, thiab muab tso rau hauv qhov chaw txias.
