Nws tsis pom zoo kom siv cov ntaub ntawv raw khoom uas tsis muaj sij hawm siv ncaj qha rau hauv lawv daim ntawv thov tseem ceeb; Txawm li cas los xij, tom qab kev muab pov tseg raws li txoj cai, ib feem ntawm cov peev txheej rov qab tuaj yeem ua tau. Cov kev siv tshwj xeeb muaj xws li:
Ua raws li kev rov qab los thiab kev ua haujlwm thib ob
Cov khoom siv hluav taws xob uas siv hluav taws xob tas sij hawm tuaj yeem raug xa mus rau cov tuam txhab tsim nyog chemical rov qab. Los ntawm cov txheej txheem xws li kev ua kom huv thiab hloov kho, lawv tuaj yeem hloov mus rau hauv cov qauv kev lag luam los tiv thaiv -corrosive primers. Cov no tsim nyog rau kev tiv thaiv xeb yooj yim ntawm cov qauv hlau thiab cov chaw sab nraum zoov nrog cov kev xav tau qis dua, yog li ua tiav cov peev txheej rov ua dua tshiab.
Downgraded siv nyob rau hauv tsis yog - cov ntawv thov tseem ceeb
Cov khoom siv tas mus li uas tau raug kuaj xyuas thiab paub tseeb tias tsis muaj cov khoom phom sij ntau dhau yuav raug diluted rau siv rau hauv ib ntus antifouling lossis tiv thaiv-kev kho xeb nyob rau hauv tsis yog- qhov chaw tseem ceeb ntawm lub chaw- xws li cov txheej tiv thaiv ib ntus rau cov khoom siv tsis siv neeg. Txawm li cas los xij, lawv yuav tsum tsis txhob siv ncaj qha rau hauv cov ntawv thov uas yuav tsum tau ua raws li nruj me ntsis, xws li ntawm cov nkoj lossis cov chaw uas tuaj yeem cuam tshuam nrog zaub mov.
Kev tsim cov peev txheej thiab rov siv dua
Tej yam khoom siv raw khoom uas tsis muaj sij hawm dhau mus lawm -tshwj xeeb hnyav- raws li cov khoom siv - tuaj yeem hloov mus rau cov kuab tshuaj siv dua los ntawm kev txiav txim siab fractional distillation thiab purification technologies. Cov kuab tshuaj siv dua tshiab no tuaj yeem siv rau hauv cov txheej txheem tsim khoom lag luam, xws li resin synthesis, yog li txo cov kev pheej hmoo cuam tshuam nrog kev pov tseg pov tseg.
