Txhua Yam Koj Yuav Tsum Paub Txog Kev Ua Phem-sensitive Adhesives hauv Kev Tiv Thaiv Zaj Duab Xis

Lub siab-rhiab nplaum nplaum siv hauvCov yeeb yaj kiab tiv thaiv tuaj yeem muab faib ua plaub pawg: roj hmab ntuj, hluavtaws roj hmab, dej-soluble acrylic, thiab hnyav-raws li acrylic. Tus yuam sij rau qhov zoo thiab qhov tsis zoo ntawm cov yeeb yaj kiab tiv thaiv yog txiav txim siab los ntawm cov yam ntxwv ntawm cov nplaum, uas muaj cov yam ntxwv sib txawv.

1. Cov roj hmab ntuj muaj cohesion siab, yog li nws feem ntau tsis tsim cov kua nplaum seem. Cov resin thiab additives tswj cov viscosity. Txawm li cas los xij, txheej txheem txheej txheej yog qhov nyuaj dua; Nws yog ib qho tsim nyog yuav tsum tau siv primer rau ntawm zaj duab xis ua ntej txhawm rau txhim kho lub zog saum npoo ntawm zaj duab xis ua ntej cov roj hmab ntuj tuaj yeem coated ntawm PE zaj duab xis.Hauv ib puag ncig sab hauv tsev, cov roj hmab ntuj tuaj yeem hloov pauv mus txog ob xyoos, tab sis nws degrades thiab muaj hnub nyoog li ntawm 3-12 lub hlis thaum raug UV teeb. UV-resistant dub thiab dawb tiv thaiv zaj duab xis feem ntau yog tsim los ntawm peb txheej: txheej sab hauv, dub, tuaj yeem nqus tau cov kab hluav taws xob ultraviolet; nruab nrab txheej, dawb, tuaj yeem cuam tshuam lub teeb kom cov yeeb yaj kiab tiv thaiv tuaj yeem nqus lub zog tsawg, txo qhov kev laus ntawm cov gel, txheej txheej: dawb: tuaj yeem npog tag nrho cov xim dub ntawm sab hauv, xim dawb tuaj yeem luam tawm. zoo nkauj dua. Yog li txawm tias tom qab 12 lub hlis ntawm kev tawm sab nraud, cov roj hmab yuav tsis muaj hnub nyoog. Tshem tawm kev txhawj xeeb ntawm cov neeg tsim khoom. Tej yam ntuj tso roj hmab muaj lub teeb daj xim. Thawj adhesion ntawm cov roj hmab ntuj yog qhov zoo, thiab nws nyuaj rau unravel cov kua nplaum thiab nplaum nyob rau hauv kev sib cuag nrog ib leeg.

2. Cov roj hmab hluavtaws tuaj yeem muab cov viscosity siab dua thiab huab cua tsis kam

Cov roj hmab hluavtaws tuaj yeem muab cov viscosity siab dua thiab huab cua tsis kam, tab sis ntev ntev, cov kua nplaum yuav kho tau, thiab qhov pib viscosity raug txo, yog li cov roj hmab hluavtaws feem ntau ntxiv rau cov roj hmab ntuj.

3. Dej-soluble acrylic yog dej ua ib qho nruab nrab kom yaj cov acrylic monomer

Raws li ntau tus phooj ywg ib puag ncig thiab tsis xav tau cov khoom siv hnyav rov qab, tsim lub teb chaws feem ntau siv cov dej-soluble colloids los tsim cov yeeb yaj kiab tiv thaiv. Cov dej-soluble acrylic muaj cov yam ntxwv ntawm cov kuab tshuaj tiv thaiv zaj duab xis. Cov nplaum nplaum ntawm cov dej-soluble tiv thaiv zaj duab xis yuav tsum zam thiab txo kev sib cuag nrog dej vapor kom tsis txhob muaj cov nplaum nplaum. Cov dej-soluble nplaum nplaum tiv thaiv zaj duab xis yog tus cwj pwm los ntawm qhov yooj yim heev thiab ceev kua muag tawm. Dej-soluble acrylic tiv thaiv zaj duab xis hauv Tebchaws Meskas thiab Asia nrog ntau heev.

4. hnyav-raws li acrylic yog siv cov kuab tshuaj organic ua ib qho nruab nrab rau yaj acrylic monomer

Acrylic nplaum yog pob tshab thiab tiv taus kev laus txog li 10 xyoo. Cov nplaum kuj kho maj mam thaum raug UV teeb. Piv rau roj hmab, acrylic nplaum muaj qhov pib qis qis. Tom qab cov yeeb yaj kiab tau kho corona, acrylic nplaum tuaj yeem siv ncaj qha yam tsis muaj primer. Acrylic films ua rau jittery, hnyav lub suab thaum unwinding, thaum cov roj hmab-raws li cov yeeb yaj kiab unwind nrog lub suab mos heev. Piv rau acrylic nplaum, roj hmab yog du heev thiab muaj fluidity zoo. Tom qab raug pressurized, nws sai sai ua tiav kev sib cuag nrog nto yuav tsum tau thov, yog li qhov tseem ceeb tshaj plaws kom zoo dua ntawm cov roj hmab-hom tiv thaiv zaj duab xis yog cov nplaum yog sai heev exerted, thiab qhov kawg adhesion yog mus txog sai sai tom qab raug pressurized los ntawm cov menyuam. . Nws yog tsim rau kev txiav los ntawm lub rooj tsavxwm Hoobkas thiab yooj yim heev rau cov neeg siv kawg los rhuav cov zaj duab xis. Rau qhov chaw ntxhib, tom qab lub siab, qhov zoo ntawm qhov zoo fluidity ntawm roj hmab molecules yog pom tseeb dua; lawv tuaj yeem nrawm nrawm rau hauv ntau yam kev nyuaj siab thiab muaj kev sib cuag tag nrho ntawm qhov chaw.

Cov roj hmab acrylic yog tawv thiab muaj kev txav tsis zoo, yog li qhov adhesion ntawm acrylic tiv thaiv zaj duab xis plays qeeb dua; Txawm tias tom qab lub siab, cov gel thiab qhov chaw yuav tsum tau tshaj tawm tseem tsis tuaj yeem tiv tauj tag nrho. Muab tso rau 30-60 hnub tom qab, nws yuav tag nrho kev sib cuag nrog rau saum npoo yuav tsum tau tshaj tawm kom ua tiav qhov kawg adhesion, thiab qhov kawg adhesion nyhav dua li qhov adhesion ntawm sticking ntawm viscosity ntawm 2-3 zaug.
