Lub melting point ntawm kub yaj yarn yog ib qho tseem ceeb ntawm kev txiav txim siab nws cov kev ua tau zoo thiab cov khoom. Nov yog qee txoj hauv kev uas qhov chaw melting tuaj yeem cuam tshuam rau cov xov paj kub yaj:
1. Adhesion zog: Lub melting point ntawm kub yaj yarn tuaj yeem cuam tshuam lub zog adhesion ntawm cov xov paj thiab cov substrate uas nws tau thov. Yog hais tias lub melting point tsawg dhau lawm, lub zog adhesion yuav tsis muaj zog, thaum lub melting point yog siab dhau lawm, lub adhesion yuav muaj zog heev thiab tej zaum yuav ua rau lub substrate puas.
2. Flow zog: Lub melting point ntawm kub yaj yarn kuj tuaj yeem cuam tshuam nws cov khoom ntws, xws li viscosity thiab fluidity. Yog hais tias lub melting point yog siab dhau lawm, cov xov paj yuav viscos heev thiab nyuaj rau thov tusyees, thaum lub melting point yog tsawg heev, cov xov paj yuav ntws sai heev thiab tsis sib xws.
3. Temperature rhiab heev: Lub melting point ntawm cov xov paj kub yaj kuj tuaj yeem cuam tshuam nws qhov kub thiab txias. Yog hais tias lub melting point tsawg dhau lawm, cov xov paj yuav ua rau melting los yog softening ntawm qhov kub thiab txias, thaum lub melting point yog siab dhau lawm, cov xov paj yuav nyuaj rau yaj los yog siv sib npaug ntawm qhov kub thiab txias.
4. Durability: Lub melting point ntawm kub yaj yarn kuj tuaj yeem cuam tshuam nws cov kav ntev thiab ua haujlwm rau ib puag ncig yam xws li cua sov thiab noo noo. Yog hais tias lub melting point tsawg dhau lawm, cov xov paj yuav ua rau melting los yog degrading thaum raug kub los yog noo noo, thaum lub melting point yog siab dhau lawm, cov xov paj yuav nruj heev thiab nkig thiab tej zaum yuav tawg los yog tawg nyob rau hauv kev ntxhov siab.
Yog li, lub melting point ntawm kub yaj yarn yog ib qho tseem ceeb hauv kev txiav txim siab nws cov kev ua tau zoo thiab cov khoom, thiab nws yog ib qho tseem ceeb kom ua tib zoo xav txog lub melting point thaum xaiv ib tug kub yaj xov paj rau ib daim ntawv thov tshwj xeeb.
