Yam cuam tshuam rau cov adhesion ntawm polyurethane log roj hmab

Cov qauv tsim ntawm cov roj hmab strips peb feem ntau siv yog tib yam li cov neeg muaj cov khoom lag luam sab nraud thiab cov khoom sab hauv ua ke. Yog li ntawd, hauv kev ua lag luam thiab cov log ntau lawm ntawm cov roj hmab polyurethane tau muaj kev cuam tshuam loj ntawm cov khoom lag luam uas tiav, thiab peb tsis tuaj yeem tsis quav ntsej txog qhov nws tau ua kom nws tau zoo. Tom ntej no, Yalide yuav tham txog qhov uas cuam tshuam rau cov nplaum ntawm polyurethane lub log roj hmab.
1. Tus qauv ntawm cov roj molecular: muaj qhov sib txheeb zoo ntawm cov polarity sib thooj thiab sib xyaw ntawm kev sib raug zoo roj hmab molecules. Qhov zoo ib yam li polarity thiab qhov zoo dua qhov sib raug zoo, qhov siab dua cov nplaum muaj zog.
2. Molecular ceeb thawj loj: ob qho siab thiab tsawg dua molecular qhov tseem ceeb tuaj yeem cuam tshuam rau cov nyhuv bonding. Tsuas yog xaiv los ntawm kev xaiv cov roj ntsha tsim nyog tuaj yeem txo tau cov roj hmab adhesion ntawm polyurethane lub log ua raws li tus qauv.
3. Kev sib xyaw ntawm cov khoom siv roj hmab: kev siv cov ntaub ntawv tsim nyog tsim nyog ua kom nruj ntawm cov roj hmab sib sib zog nqus, Rosin, Qaij vab tshaus tuaj yeem ua rau lub viscules Tsevneeg zog ua lub zog.
4. Nto Lub Xeev ntawm cov nplaum: Cov yeeb yaj kiab oxide, cov kab tsuag dej khov, thiab tso tawm tus neeg sawv cev los ntawm cov nplaum ntawm cov nplaum. Yog li ntawd, ua ntej kev sib koom tes, cov hau kev tsim nyog yuav tsum tau siv los kho qhov chaw ntawm cov nplaum, xws li cov kuab khoom so, xws li rouging, thiab lwm yam.
5. Qhov ceev ntawm cov kuab tshuaj evaporation: Thaum peb siv cov kuab tshuaj ua kom ncaj, nws yooj yim rau cov kuab tshuaj uas muaj zog los tsim cov hws. Ob qho tib si nrawm thiab qeeb qeeb tsis muaj peev xwm ua rau kom muaj kev sib raug zoo. Yog li ntawd, thaum xaiv cov kuab tshuaj sib xyaw uas sib txuas ua ke kom nrawm thiab qeeb qeeb, cov nyhuv yuav zoo dua. Cov kuab tshuaj uas tsis tshua muaj kuab kuj tseem tuaj yeem siv ntau zaus rau cov log hlau, thiab cov nyhuv kuj zoo.
Ntxiv rau tsib yam uas tau hais los saum toj no uas tuaj yeem cuam tshuam rau txoj kev sib txuas lus zoo ntawm polyurethane siv tau nws lub zog rau qee yam. Cov haujlwm nplaum ua haujlwm ua haujlwm tseem ceeb hauv kev tsim khoom thiab kev tsim cov khoom lag luam, kom tsis txhob muaj kev sib txawv ntawm kev siv tom qab.
