Yuav Siv Polyamide Adhesive li cas

Lub melting kub ntawm polyamide kub yaj adhesives yog, nyob rau hauv nqe lus txiav txim: 140-160 degree, (165 ± 5) degree, thiab (200 ± 5) degree. Hauv shoemaking, peb cov nplaum nplaum kub kub no, nrog cov ntsiab lus softening los ntawm qhov siab tshaj mus rau qis tshaj, yog siv rau molding thiab nias tawv khau tom qab ntev, txias - nias tawv khau tom qab ntev, thiab tawv edging.

Txij li thaum polyamide kub yaj nplaum nplaum tuaj yeem siv rau ntawm qhov kub txog li 200 degree, 1% ntawm 1-phenyl-3-pyrazolidine lossis 1-phenoxy-3-pyrazolidine feem ntau yuav tsum tau ntxiv rau hauv cov qauv los tiv thaiv kev laus. Tom qab ntxiv pyrazol rau cov kua nplaum, txawm tias nyob rau hauv kev nrawm nrawm ntawm 260℃rau 6 teev, nws khaws nws cov khoom qub.
