Kev Kho Mob Kub Melt Pressure Sensitive Adhesive Standards

Kev Kho Mob Kub Melt Pressure Sensitive Adhesive (HMPSA) muaj cov cai tshwj xeeb thiab cov qauv rau nws daim ntawv thov hauv cov ntaub ntawv kho mob. Kev siv dav hauv kev tsim cov khoom siv kho mob xws li cov ntaub ntawv kho mob, cov ntaub so ntswg, thiab cov ntaub qhwv lub qhov txhab, HMPSA nthuav tawm ob qho tib si kub yaj thiab lub zog-rhiab heev. Nws xav tau cov cuab yeej tshwj xeeb rau cua sov thiab melting thaum lub sijhawm tsim khoom, ua kom pom nws cov yam ntxwv kub yaj. Thaum ua ntawv thov, cov khoom siv nplaum kho mob zoo li cov ntaub nplaum thiab cov ntaub qhwv lub qhov txhab ua raws li cov ntiv tes siab, qhia txog lawv qhov siab-rhiab heev. Hauv kev ua lag luam daim kab xev kho mob, HMPSA yuav tsum ua kom tau raws li cov txheej txheem dhau los tsuas yog siv tau thiab thermal stability. Nws yuav tsum muaj cov khoom xws li tsis khaus khaus, conformability, thiab breathability.

• Kev Siv Tau: HMPSA tuaj yeem siv tau siv cov nozzles tshwj xeeb lossis cov chais mus rau ntau lub substrates. Txawm li cas los xij, HMPSA siv rau cov ntaub ntawv kho mob feem ntau muaj cov kua dej ntau, uas tuaj yeem ua rau cov dej ntws tawm thaum siv rau cov dej ntxeem tau. Tsis tas li ntawd, ntau daim kab xev kho mob tsis tuaj yeem tiv taus cua sov thiab tuaj yeem ncab, deform, lossis tawg thaum siv. Txhawm rau daws cov teeb meem no, cov tuam txhab lag luam feem ntau siv HMPSA tso tawm cov ntawv uas tuaj yeem tiv taus qhov kub thiab txias ua ntej hloov mus rau ntau lub substrates.
• Tsis-khaus: Cov kuab tshuaj raws li cov nplaum uas 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 thiab txhim kho kev nqus dej los yog hws-wicking peev xwm.
• Conformability: Ntuj tackifying resins xws li rosin lossis esterified rosin tsis haum rau cov ntaub ntawv kho mob. Yog li ntawd, kev ua tiav ntawm daim tawv nqaij conformability nyob ntawm qhov muag muag thiab ntub dej ntawm HMPSA nws tus kheej, hu ua tackiness. Thaum tsim HMPSA rau daim kab xev kho mob, yuav tsum tau muab tso rau ntawm nws cov flowability ntawm tib neeg daim tawv nqaij. Thaum thov, daim kab xev yuav tsum tsis tu ncua ntub thiab ua raws li daim tawv nqaij nto. Qhov zoo tshaj plaws, daim kab xev yuav tsum tsis txhob nqa lossis tev tawm vim kev khoov lossis txav ntawm pob qij txha.
• Ua tsis taus pa: Txhawm rau txo qhov khaus ntawm daim tawv nqaij, HMPSA rau cov ntaub ntawv kho mob feem ntau tsis suav nrog cov tshuaj polar (hydrophilic polymers) ua cov khoom siv vim lawv tsis nqus dej los yog hws. Txhawm rau ua kom muaj pa txaus, cov pinholes tuaj yeem raug punched hauv daim kab xev substrate nrog rau cov nplaum tom qab daim ntawv thov, lossis cov khoom siv tshwj xeeb txheej tuaj yeem tsim tsis muaj kev tiv thaiv tag nrho, tawm hauv qhov ua pa ntawm cov nplaum nplaum. Ob txoj kev tso cai rau kev kho mob tapes kom tau ib theem ntawm breathability.
