Kev kho mob kub yaj siab-rhiab nplaum nplaumyog ib qeb ntawm kev kho mob kub yaj nplaum nplaum siv dav hauv kev ua thiab tsim cov khoom kho mob thiab cov khoom siv huv huv xws li daim kab xev kho mob, cov kab mob infusion, thiab cov ntaub qhwv lub qhov txhab. Nws muaj ob qho tib si kub yaj cov khoom thiab lub zog-rhiab heev, yuav tsum tau cov cuab yeej tshwj xeeb rau cua sov thiab melting thaum lub sij hawm tsim cov khoom nplaum, ua kom pom nws cov kub yaj xwm. Cov khoom ua los ntawm kev kho mob kub yaj siab-rhiab nplaum nplaum, xws li daim kab xev kho mob thiab cov ntaub qhwv lub qhov txhab, nthuav tawm cov khoom nplaum thaum tsim kua muag thiab tuaj yeem ua raws li tus ntiv tes siab, qhia txog nws qhov siab-rhiab qhov xwm txheej.
Kub yaj siab-rhiab nplaum nplaum siv nyob rau hauv kev kho mob daim kab xev lag luam tsis tsuas yog yuav tsum tau txheej txheej workability thiab thermal stability tab sis kuj yuav tsum muaj cov yam ntxwv xws li tsis khaus, adhesion, thiab breathability.
Txheej Ua Haujlwm Raws li tau hais ua ntej, kub yaj siab-rhiab nplaum nplaum tuaj yeem siv rau ntau yam tshwj xeeb substrates siv tshwj xeeb dies lossis rollers. Txawm li cas los xij, kub yaj siab-rhiab nplaum nplaum rau cov ntaub ntawv kho mob feem ntau muaj cov dej ntws zoo, ua rau lawv yooj yim dhau mus rau hauv cov dej ntxeem tau, ua rau cov nplaum nplaum. Tsis tas li ntawd, ntau lub substrates siv rau cov ntaub ntawv kho mob tsis tuaj yeem tiv taus qhov kub thiab txias thiab tej zaum yuav muaj kev elongation, deformation, los yog kev puas tsuaj thaum lub sij hawm siv nplaum. Txhawm rau daws cov teeb meem no, cov tuam txhab lag luam feem ntau ua ntej siv cov nplaum nplaum kub-sensitive los tso cov ntawv uas tuaj yeem tiv taus qhov kub thiab txias thiab tom qab ntawd hloov cov nplaum mus rau ntau lub substrates.
Tsis-khaus khaus Solvent-based adhesives feem ntau siv hauv cov ntaub ntawv kho mob tuaj yeem ua rau tawv nqaij ua xua, yuav tsum tau ntxiv zinc oxide hmoov rau cov nplaum. Zinc oxide ua haujlwm rau ob lub hom phiaj: txo qhov ua xua ntawm cov kuab tshuaj raws li cov nplaum nplaum ntawm daim tawv nqaij thiab txhim kho cov nplaum cov dej noo los yog hws-absorbing peev xwm.
Adhesion Txij li thaum ntuj tackifying resins xws li rosin los yog esterified rosin tsis haum rau cov ntaub ntawv kho mob, adhesion rau ntawm daim tawv nqaij yog nyob ntawm qhov yooj thiab ntub cov khoom ntawm kub yaj siab-rhiab nplaum nplaum nws tus kheej, hu ua cohesive elasticity. Thaum tsim cov kub yaj lub siab-rhiab nplaum nplaum rau cov ntaub ntawv kho mob, tshwj xeeb yuav tsum tau them rau cov flowability ntawm tib neeg daim tawv nqaij. Tom qab daim kab xev yog siv rau ntawm daim tawv nqaij, nws yuav tsum tsis tu ncua ntub dej thiab ua raws li daim tawv nqaij nto, zoo tagnrho nyob ruaj ruaj nyob rau hauv qhov chaw txawm tias thaum sib koom tes thiab khoov.
Ua pa kom tiv thaiv tawv nqaij, kub yaj siab-sensitive adhesives siv nyob rau hauv kev kho mob tapes feem ntau tsis muaj polar tshuaj (hydrophobic siab polymers). Qhov no yog vim cov tshuaj polar tsis tuaj yeem nqus dej los yog tawm hws. Txhawm rau ua kom muaj kev ua pa zoo, cov pinholes tuaj yeem tsim nyob rau hauv daim kab xev substrate nrog rau cov nplaum, los ntawm perforating daim kab xev tom qab daim ntawv thov nplaum los yog siv cov cuab yeej tshwj xeeb txheej los tsim kom tsis muaj kev tiv thaiv tag nrho, tsim qhov ua pa ntawm qhov chaw coated. Ob txoj hauv kev tuaj yeem muab qee qhov kev ua pa rau cov ntaub ntawv kho mob.
Lwm Cov Khoom Siv Lub Cev Cov nplaum nplaum rau cov ntaub nplaum kho mob yog tib neeg cov tawv nqaij, uas feem ntau muaj qhov kub thiab txias ntawm 30 txog 35 degree txhua lub sijhawm thiab qhov chaw. Yog li ntawd, ntxiv rau kev txiav txim siab seb puas kub yaj siab-rhiab nplaum nplaum yuav ua rau cov nplaum nplaum dhau vim muaj dej ntau dhau thaum lub sijhawm khaws cia thiab kev thauj mus los, kev kho mob kub yaj siab-rhiab nplaum nplaum tsis tas yuav tsum tau saib xyuas tshwj xeeb rau kev tiv thaiv kub thiab txias, tsis zoo li daim kab xev thiab cov ntawv lo rau. lwm lub hom phiaj. Txawm li cas los xij, kev hloov pauv ntawm cov tawv nqaij qhuav thiab oiliness tuaj yeem ua rau cov neeg siv ntsib ntau theem ntawm adhesion thiab tackiness.
