Raw Materials Rau Kub-melt Adhesives

Tackifiers
Tackifiers yog ib qho tseem ceeb ntxiv rau EVA kub-cov nplaum nplaum. Relying tsuas yog nyob rau hauv kev sib koom ua ke lub zog ntawm lub hauv paus molten resin yog tsis txaus; Raws li qhov kub thiab txias poob, cov nplaum nplaum tsis txaus ntub los yog nkag mus rau hauv daim ntawv, yog li poob nws cov peev xwm sib txuas thiab tsis ua tiav qhov kev xav tau. Kev sib koom ua ke tackifiers txhim kho cov nplaum nplaum fluidity thiab wettability ntawm lub substrate, txhim kho kev sib raug zoo, thiab ua kom lub zog ntawm daim ntawv cog lus. Cov tackifiers muaj xws li rosin, hloov rosin (qib 138 lossis 145), C5 roj av resins, C9 roj av resins, thiab terpene resins.

 

Viscosity Modifiers
Viscosity modifiers yog lwm qhov tseem ceeb additives rau kub -melt adhesives. Lawv ua hauj lwm kom muaj fluidity thiab tswj tus nqi solidification, pab kom ceev thiab ruaj ntseg kev sib raug zoo. Yog tsis muaj lawv, cov nplaum nplaum yuav siab dhau - cuam tshuam kev ntws thiab tiv thaiv kev nkag mus rau hauv phau ntawv kos npe, uas yuav ua rau muaj kev cuam tshuam tsis zoo. Ntxiv qis -softening-point viscosity modifiers ua kom muaj kev nkag tau zoo thiab muaj zog, ruaj ntseg daim ntawv cog lus. Cov kev xaiv muaj xws li paraffin wax, microcrystalline wax, hluavtaws waxes (PE lossis PP), thiab Fischer-Tropsch wax.

 

Antioxidants
Qhov tsim nyog ntawm cov tshuaj antioxidants ntxiv los tiv thaiv kev laus ntxov ntxov ntawm EVA kub- cov nplaum nplaum. Txij li thaum cov nplaum tuaj yeem ua rau oxidative decomposition ntawm qhov kub siab uas yuav tsum tau ua rau melting, antioxidants xyuas kom meej tias kev sib txuas ua haujlwm tseem nyob ruaj khov nyob rau hauv cov kev kub siab no -.
