Qhov feature ntawm UF lub rooj zaum tso quav

Urea formaldehyde (UF）toilet roojFeem ntau yog siv los npaj cov amino alkyd ci xim nrog alkyd resin los txhim kho hardness thiab dryness ntawm xim zaj duab xis. UF lub rooj zaum tso quav tuaj yeem ua ke nrog cov tsis ziab alkyd resin los ua kua qaub kho cov xim amino, uas tuaj yeem siv rau lub teeb npog ntawm cov rooj tog ntoo. Tab sis huab cua tsis kam, dej tsis kam thiab lub teeb tuav tsis zoo me ntsis. Epoxy resin thiab alkyd resin tuaj yeem siv los npaj cov primers thiab cov xim sab hauv tsev nrog cov khoom sib txawv. Cov yam ntxwv tseem ceeb muaj xws li:

1. Tus nqi ntawmlub rooj zaum UFyog pheej yig thiab cov ntaub ntawv raw txaus.

2. Cov qauv molecular ntawmurea formaldehyde (UF) chav dejmuaj polar oxygen atoms, yog li nws muaj adhesion zoo rau saum npoo. Nws tuaj yeem siv rau primer thiab nruab nrab txheej los txhim kho qhov adhesion ntawm topcoats.

3. vimUF rooj zaumtuaj yeem kho tau ntawm chav tsev kub thaum siv cov kua qaub catalyst, nws tuaj yeem siv rau ob qho khoom siv ntoo.

4. Cov xim zaj duab xis kho nrog urea formaldehyde resin muaj qhov ua tau zoo.

5. Urea formaldehyde resin muaj viscosity siab, siab acid nqi thiab tsis zoo cia stability.
