Moisture-Kev ntsuas pov thawj rau cov ntsia hlau

Hlau ntsia hlau yog nquag rusting nyob rau hauv qhov chaw ntub dej; yog li ntawd, cov dej noo- pov thawj yog tsim nyog los tiv thaiv corrosion.

Cov txheej txheem rau ya raws - pov thawj screws yog raws li nram no:

(1) Rau cov tshuab vibrating, siv cov kuab tshuaj- cov kua roj vanish dawb thaum twg los tau.

(2) Qhov zoo tshaj plaws, xaiv impregnating varnishes uas tsis muaj oxidizing Cheebtsam, xws li epoxy-urethane los yog unmodified epoxy{2}}raws li varnishes.

(3) Thaum siv melamine-alkyd impregnating varnishes, qhov kub thiab lub sij hawm yuav tsum tau ua tib zoo kho. Kev kho kub me ntsis siab dua 130℃(piv txwv li, 135 degree) thiab lub sijhawm kho ntau tshaj 180 feeb yog pom zoo. Kev ua raws li cov txheej txheem nruj me ntsis yog qhov tseem ceeb - tshwj xeeb tshaj yog thaum lub caij kub, ntub dej - vim tias qhov ziab (kho) lub sij hawm teev nyob rau hauv cov xim manufacturers cov ntaub ntawv cov ntaub ntawv tej zaum yuav tsis txaus muab qhov tshwj xeeb geometry ntawm lub cev muaj zog.

(4) Siv cov kua roj vanish uas tsis muaj volatile acids.

(5) Xaiv cov kua roj vanish nrog zoo hydrolysis tsis kam.
