Dab tsi yog cov khoom xyaw hauv cov kua nplaum kub yaj

1. Basic cob

 Qhov yooj yim resinofkub yaj nplaum-resin yog tsim los ntawm copolymerization ntawm ethylene thiab vinylacetate nyob rau hauv qhov kub thiab txias. Resin yog qhov tseem ceeb ntawm kev ua kom kub yaj nplaum nplaum. Nws yog tsim raws li qhov yuav tsum tau ua piv txwv, thiab feem ntau suav rau 40% ntawm cov nplaum kub yaj. ~ 60%.

2. Tackifier

 Tackifiers yog ib qho ntawm cov khoom tseem ceeb ntawm cov nplaum kub yaj. Yog tias tsuas yog siv cov khoom siv yooj yim xwb, nws tsuas yog muaj lub zog sib txuas thaum nws melts ntawm qhov kub thiab txias.Thaum qhov kub thiab txias poob, qhov kev sib txuas yuav tsis muaj zog, thiab nws yuav poob nws lub peev xwm sib txuas. Daim ntawv tso tseg tsis ntub thiab ntub dej, thiab qhov zoo tshaj plaws bondingeffect tsis tuaj yeem ua tiav.

3. Viscosityconditioner

Viscosityconditioner kuj yog ib qho ntawm cov khoom tseem ceeb ntawm cov nplaum kub yaj. Nws txoj haujlwm yog los txo cov yaj viscosity, nce kev txav mus los, wettability, thiab kho cov khoom nrawm kom ua tiav lub hom phiaj ntawm kev sib txuas ceev thiab ruaj khov.

 

4. Antioxidant 

Lub colloid yuav oxidized thiab synthesized vim lub siab kub thaum nws yog melted.Ntxiv ib tug tsim nyog tus nqi ntawm antioxidant yuav zam lub ntxov ntxov laus ntawm cov kub yaj nplaum. Tsis tas li ntawd, nyob rau hauv qhov kub thiab txias, nrog rau qhov tsim nyog tus nqi ntawm cov tshuaj antioxidants, cov viscosity ntawm cov nplaum yuav tsis hloov, uas yog txaus los xyuas kom meej cov nyhuv ntawm cov phau ntawv.
