Raws li cov khoom siv kawg-lub ntsej muag kua nplaum yuav ua rau muaj kev puas tsuaj rau cov cuab yeej, yog tias hnyav, nws tseem yuav cuam tshuam rau lub tshuab ua haujlwm, peb yuav daws nws li cas?

Cia ua ib qho kev sim ua ntej. Muab ibself-adhesive daim ntawv lonyob rau sab saum toj ntawm lub teeb ntxoov ntxoo ntawm lub rooj teeb, thiab tom qab ntawd rhuav tshem nws, kom cov seem uas muaj residue nyob rau saum npoo ntawm lub teeb ntxoov ntxoo, raws li pom hauv daim duab 2(a). Xaiv cov nplaum nplaum kub thiab cov ntaub nplaum emulsion tau raug sim, cov khau dawb polished so rau ntawm cov nplaum nplaum, sab laug rau li 20min, thiab tom qab ntawd so nrog ib daim ntaub, qhov tshwm sim ntawm lub teeb ntxoov ntxoo saum npoo daim ntawv lo residue tag nrho wiped tawm, raws li qhia hauv daim duab 2 (b). Qhov no qhia tau hais tias khau polish thiab cov ntawv nplaum muaj cov tshuaj tiv thaiv, uas yog hais tias, cov roj hauv cov khau polish tuaj yeem yaj nrog cov ntawv nplaum, kom cov nplaum nplaum, softening, cohesion txo. Yog li ntawd, siv cov khau dawb tuaj yeem tshem tawm cov nplaum los yog daim ntawv lo ntawm qhov chaw ntawm qhov khoom.

Raws li lub hauv paus ntsiab lus no, peb tau teeb tsa cov roj formula raws li qhov sib piv ntawm 80 feem pua ​​​​ntawm butter thiab 20 feem pua ​​​​ntawm cov roj tshuab, thiab siv nws sib npaug ntawm cov nplaum nplaum nrog daim ntaub qub. Tom qab li ntawm ib nrab teev, cov nplaum nplaum tau muag thiab diluted, thiab cov khoom siv tuaj yeem tig rau ib txwm, raws li pom hauv daim duab 3(b). Nws yog ib qho tsim nyog sau cia tias txoj kev no tsuas yog softened cov nplaum, cov nplaum tseem muaj nyob rau hauv lub hom phiaj, yog li kev ua haujlwm tu ntawm cov ntawv xa khoom ntawm cov khoom siv yuav tsum tau ua.

Cov kev daws teeb meem tsis tsuas yog txhim kho qhov teeb meem ntawm unwind sticking, tab sis kuj txhim kho qhov adhesion ntawm cov nplaum nplaum rau cov ntawv qhia yob thiab baffle, uas pab txhawb kev tu tom ntej thiab tuaj yeem tiv thaiv cov khoom tawg. Ntawm chav kawm, cov npoo ntawm cov khoom yog kis nrog roj, tab sis thaum kawg lawv raug tshem tawm tom qab scrapping thiab slitting, uas tsis cuam tshuam rau qhov zoo ntawm cov ntawv tiav, raws li qhia hauv daim duab hauv qab no.
