Taw qhia ntawm Nto Kho Txheej Txheej rau Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Lub Tshuab nqus tsev tso tawm tshuab

Txheej yog cov khoom siv txuas ntxiv uas tau txais los ntawm ib daim ntawv thov ntawm cov xim, uas yog txheej nyias nyias siv rau hlau, ntaub, yas, thiab lwm yam substrates rau kev tiv thaiv, rwb thaiv tsev, kho kom zoo nkauj, thiab lwm yam. Cov txheej txheem tuaj yeem yog gaseous, kua, lossis khoom, thiab hom thiab lub xeev ntawm txheej txheej feem ntau txiav txim siab los ntawm substrate yuav tsum tau txau.

Cov txiaj ntsig ntawm txheej txheej:

Taw qhia ntawm Nto Kho Txheej Txheej rau lub tshuab nqus tsev tso tawm

1. Nto kho cov txheej txheem

Lub hauv paus ntsiab lus ntawm permeable nto kho coatings yog siv ib tug resin nrog muaj zog permeability raws li lub hauv paus, ua ke nrog polar solvents thiab nkag mus rau cov neeg sawv cev los xyuas kom meej kev ua tau zoo thiab txhim khu lub adhesion ntawm txheej.

2. ruaj khov txheej txheej

Lub hauv paus ntsiab lus ntawm kev ruaj ntseg txheej txheej txheej feem ntau yog nyob ntawm cov tshuaj tiv thaiv ntawm cov khoom siv raw hauv txheej txheej thiab cov khoom siv hauv cov txheej xeb. Cov khoom siv raw khoom siv feem ntau suav nrog zinc oxide

Zinc phosphate, zinc chromate, barium chromate, organic nitrogen hauv paus chromate, calcium chromate, aluminium tripolyphosphate, sodium nitrite yog ntxiv rau qee cov qauv, thiab strontium chromate yog xav tau.

3. Hloov hom kev kho deg txheej

Transforming nto kho coatings, tseem hu ua reactive xeb resistant coatings, tsis muaj film-forming tshuaj thiab yog li ntawd yuav tsum tau ntxiv primer kev sib koom tes. Yog tias lawv muaj cov khoom ua yeeb yaj kiab, lawv hu ua xeb resistant conversion primers.
