Qhov kev cuam tshuam dab tsi ntau dhau siab muaj ntau dhau ntawm cov nplaum ntawm silicone embossing?
Kev ntsuas kub ntau dhau ntawm qhov cuam tshuam ntawm cov nplaum ntawm silicone embossing los ntawm peb qhov tseem ceeb:Silicone pre - kho, substrate stability, thiab interface bonding zooCov. Cov kev cuam tshuam tshwj xeeb yog raws li hauv qab no:
1. Cov lus tsis raug sau tseg "ua ntej ua ntej {1} Kho" ntawm silicone, poob nws lub peev xwm ua raws li thiab nkag mus
Thermosetting embossing silicone yuav tsum tau "tswj tau kho" ntawm qhov ntsuas kub ntawm cov khoom siv embossing. Txawm li cas los xij, kev kub siab ntau dhau los yog cov khoom siv kub (piv txwv li ntawm 35 degree, nrog kev sib txawv tshwj xeeb sib txawv los ntawm silicone hom) muaj peev xwm ua rauUnintended Pre - kho:
Ua ntej silicone tuaj rau hauv kev sib cuag nrog lub substrate, nws cov lwg me nyuam uas twb pib ib nrab hla}}} kev xa tawm hauv fluidity. Raws li qhov tshwm sim, nws tsis tuaj yeem sau cov kab ntawv khoob ntawm cov npoo av (xws li cov khoob ntawm cov nplais lossis cov me me indentations lossis me me indentations ntawm yas). Cov "kev sib cav sib ceg" ua haujlwm tau tsim los ntawm "lub cev ua kom ploj" ploj, thiab tsuas yog ntiav cov nplaum sab saum toj yog ua tiav {}} pinning yooj yim tshwm sim hauv kev quab yuam.
Yog tias pre {- kev kho mob yog mob hnyav, cov tawv nqaij silicone "nyuaj {{1} Kuv yog txheej txheej. Thaum lub sij hawm embossing, nws ua tsis tau raws li txoj kev ua kom ze rau saum npoo av, tsim cov khoob me me ntawm lub interface. Qhov no ncaj qha txo qhov chaw ua kom zoo dua qub, ua rau muaj kev poob qis hauv adhesion.
2. Kev puas tsuaj substrate stability, undermining lub hauv paus ntawm interface bonding
Qee cov embossting substrates (piv txwv li, lub teeb- melting {}}} tawv {}}- kub tsis kam. Ntau dhau kev kub siab tuaj yeem ua rau lawvdeform, hnub nyoog, lossis poob saum npoo:
Substrate deformation (xws li cov ntaub qhwv lossis yas warping) ua rau tsis ncaj ntawm silicone thiab substrate thaum lub sij hawm pob zeb, ua rau "ib feem uas tsis muaj zog" hauv qee thaj chaw.
Substrate Doain Kev Laus (xws li ntaub fiber ntau embrittlement lossis cov pab pawg yas ua kom puas tsuaj rau cov pab pawg ua kom puas tsuaj) Tsawg cov hom phiaj kev ua haujlwm txhais tau cov tshuaj sib koom tes tsis tuaj yeem ua tsis tau, thiab adhesion poob nws cov tseem ceeb txhawb nqa.

Cov ntsiab lus tseem ceeb hauv cov mis nyuj silicone, xws liAdhesion txhawb nqa (piv txwv li, kev sib tshuam sib txuas ntawm cov neeg sawv cev)thiabTshuaj Tiv Thaiv, muaj qhov kub ua kom sov kub ua kom tau:
Kev sim siab kub ua rau cov kev txiav txim siab ntawm cov neeg sawv cev sib txuas, ua haujlwm ntawm lawv "Bridging ua haujlwm" (ib qho kawg ntawm txoj haujlwm sib dhos, thiab lwm qhov kawg reacts nrog cov pab pawg subtoms). Cov tshuaj lom neeg sib zog ntawm silicone thiab lub substrate tawg, thiab cov nplaum tsuas yog tswj los ntawm cov tsis muaj zog cuam tshuam, ua rau muaj kev txo qis.
Yog tias peroxide {{0-} Ua cov neeg sawv cev yog siv, qhov kub siab yuav ua rau lawv cov kev txiav txim siab ntau dhau. Lub txiaj ntsig los ntawm - cov khoom (piv txwv li, kev tiv thaiv kev sib cais ntawm ob thiab ntxiv mus ntxiv rau cov adhesion.
