Tackifier yog ib qho tseem ceeb ntxiv ntawm EVA kub yaj kua nplaum. Yog tias tsuas yog cov ntawv nplaum yooj yim muaj qhov nplaum lub zog ntawm qhov ntsuas kub thaum nws yaj, nws yuav nyuaj rau ntub thiab nkag rau hauv daim ntawv tom qab qhov kub thiab txias, thiab lub peev xwm nplaum yuav ploj, thiab cov nplaum ua haujlwm yuav tsis tiav; nyuam qhuav ntxiv ib rab tshuab tsoo. Txhim kho qhov kev npliag ntawm colloid thiab lub ntub ntawm lub nplaum, txhim kho kev sib khi, thiab ua tiav lub zog ua kom muaj zog. Cov nplais siv dav dav suav nrog rosin, hloov rosin (138 lossis 145), C5 roj av roj av, C9 roj av roj av, terpene cob, thiab lwm yam.
Viscosity hloov kho kuj tseem yog ib qho tseem ceeb ntxiv ntawm kub yaj nplaum nplaum. Nws txoj haujlwm yog nce lub fluidity ntawm colloid thiab kho qhov ceev solidification kom tau txais lub hom phiaj ntawm kev ua haujlwm nrawm thiab kev ruaj khov. Txwv tsis pub, cov viscosity ntawm cov kub yaj nplaum yog qhov loj heev, tsis tuaj yeem lossis ntws nyuaj, thiab nws nyuaj rau nkag rau hauv kos npe, yog li nws tsis tuaj yeem ua kom sib haum. ruaj. Ntxiv cov viscosity hloov kho nrog qhov ua kom tsis muaj qhov muag tuaj yeem ua kom tiav lub hom phiaj ntawm kev nkag mus kom zoo thiab khov kho thaum sib khi. Feem ntau xaiv paraffin siv quav ciab, microcrystalline siv quav ciab. Synthetic siv quav ciab (PE lossis PP), Foto siv quav ciab, thiab lwm yam.
Ntxiv qhov tsim nyog ntawm cov antioxidant yog los tiv thaiv ntxov ntxov ntawm EVA kub yaj lub nplaum. Vim hais tias cov kem xim yuav oxidize thiab decompose thaum kub dhau heev thaum melting, ntxiv ntawm antioxidant tuaj yeem xyuas kom meej tias qhov kev sib khi tsis hloov pauv nyob hauv siab kub.
