dab tsi yog lub siab rhiab nplaum
Feem ntau cov tapes peb ntsib hauv lub neej txhua hnub yog cov qeb ntawm lub siab {{rhiab} Cov nplaum}) cov khoom lag luam. Lawv cov cim tshwj xeeb nyob hauv lawv cov semi- chaw lub xeev ntawm chav tsev kub. Tsis muaj cua sov, kev sib xyaw, lossis kho cov txheej txheem kho tau zoo thaum siv {4 4}} yooj yim thov kom lawv muaj zog sib raug zoo nrog rau saum npoo ntawm adherend. Qhov no zoo tshaj plaws "xovxwm - rau {- tus nplaum" cov khoom los ntawm nws cov pib
Viscoelastic ntawm Adhesive
Txhawm rau nkag siab cov siab - Cov khoom nplaum rask, ib qho yuav tsum ua ntej cov khoom ntiag tug ntawm lawv lub npe Polymer hu ua Visoelasticity. Raws li lub npe qhia, cov cuab yeej no qhia tau tias cov khoom siv ua pov thawj ob qho tib si "viscosity" ntawm ib qho kua thiab "elasticity" ntawm ib qho khoom.
Elastic
Zoo li lub caij nplooj ntoo hlav, nws deforms tam sim ntawd hauv qab kev quab yuam tab sis tam sim ntawd rov qab rau nws cov qauv qub thaum lub zog raug tshem tawm. Qhov no revormation thuam cov cwj pwm ntawm kev coj cwj pwm ntawm ib qho zoo tagnrho. Nws cov me me mechanism stems los ntawm kev hloov pauv ntawm cov ces kaum sib khi tsis pub dhau cov kab ke polymer molecular. Qhov no tso cai cohesive lub zog rau cov nplaum, ua rau nws tiv thaiv peeling thiab tswj nws lub ncaj ncees.
Viscosity
Zoo li piston nyob rau hauv lub lauj kaub viscous, nws undergoes qeeb, tsis muaj dej ntws hauv qab sab nraud. Qhov kev tsis txaus ntseeg no ua rau muaj kev sib tw viscous, zoo li tus cwj pwm ntawm cov kua zoo tagnrho. Nws cov meccocochism muaj me ntsis cov lus swb thiab repositioning ntawm polymer chains. Nws yog precisely cov xeeb ceem uas ua rau cov nplaum kom ntws zoo li cov kua hauv siab thiab ntub dej ntawm substrates. Cov khoom ntws no yog qhov tseem ceeb rau PSA lub peev xwm los ntub cov chaw substrate.
Yuav ua li cas kom ua tiav kev ua tiav kev ua tau zoo
Nyem
Thov maj nrawm thiab siab kom ua kom tiav cov nplaum "VANCO} Kuv tso cai rau qhov chaw microscopic, yog li nthuav dav lub cev thaj chaw.
01
Sij hawm
Qhov nce hauv txoj kev sib raug zoo ua kom muaj zog yuav tsum muaj sijhawm. Qhov no yog vim tias cov nplaum ntws thiab ntub dej ua tsis tiav; Lawv xav tau lub sijhawm nyob hauv lub sijhawm kom ua tiav qhov kev pom zoo.
02
Qho so
Muaj kev nce qib hnyav tuaj yeem ua kom nrawm dua kev txav ntawm polymer lwg me me, ua cov nplaum ntxiv "hloov tau ntau dua" thiab yooj yim dua. Qhov no tseem ceeb ua rau cov txheej txheem ntub dej thiab tso cai rau cov nplaum kom ncav cuag nws qhov kev sib tw kawg ua kom sai.
03
Nplaim
Qhov ua tiav lossis tsis ua tiav ntawm adhesion thaum kawg nyob ntawm lub zog saum npoo ntawm cov ntaub ntawv cog lus. Rau cov ntaub ntawv nrog cov hlau loj (xws li hlau) lossis qis dua li plastics), nws yog qhov tsim nyog los xaiv lawv cov khoom kom ua tiav kev ua kom pom kev zoo thiab ua kom tiav.

Cov Khoom Siv Xa Khoom
Yog tias koj xav paub txog cov kev paub no, koj tuaj yeem tiv tauj peb txhua lub sijhawm, lossis koj tuaj yeem nyem xav paub ntxiv rau qhov txuas ntawmKub yaj siab siab rhiab nplaum
