Powder coatings curing txheej txheem nyob rau hauv qhov cub

Hmoov txheej tua txheej txheem hauv qhov cub muaj peb theem.

Ua ntej, cov khoom siv yog yaj, tom qab ntawd lawv sib xyaw ua ke, thiab thaum kawg lawv tsim cov yeeb yaj kiab los yog txheej txheej saum npoo.
Kev tuav cov viscosity tsawg ntawm cov txheej rau lub sijhawm tsim nyog yog qhov tseem ceeb heev kom muaj qhov sib luag thiab txawm nto. Muaj tsawg zuj zus thaum lub sij hawm txheej txheem kho, viscosity yuav nce sai li sai tau thaum cov tshuaj tiv thaiv (gelling) pib. Yog li, reactivity thiab kub kub muaj lub luag haujlwm tseem ceeb hauv kev tsim cov theem saum npoo.
Yog li ntawd, ntau reactivity ntawm txheej, qhov tshwm sim sai ntawm gelling thiab nce viscosity, yog li ntawd, lub txheej txheej ntawm txheej yuav ntau undulant (txiv kab ntxwv tev). Tsis tas li ntawd, kev kho sai sai ua rau txo qis ntawm melted viscosity.

Particle loj tis ntawm cov txheej kuj ua tau zoo nyob rau hauv lub xeev thiab levelness ntawm qhov chaw. Yog li ntawd, piv rau cov khoom loj, cov khoom me me ua ke nrog lwm tus hauv lub sijhawm luv. Kev tshem tawm cov khoom loj dua tuaj yeem ua rau muaj qhov zoo nkauj thiab ci ntsa iab nrog cov yeeb yaj kiab thinner.
