Txhawm rau kom tau raws li cov kev xav tau ntawm cov neeg siv, kho kom zoo nkauj txhuas daim hlau feem ntau kho tau saum npoo ua ntej lawv tuaj yeem ua lag luam. Yog li ntawd, qhov saum npoo kev kho kom zoo nkauj ntawm daim phiaj txhuas hniav yog qhov tseem ceeb dua. Yuav ua li cas teeb tsa cov phaj txhuas hniav thiab yuav ua li cas tiv thaiv cov nplaim ntawm cov phaj txhuas hniav? Cia' s sib tham txog txheej txheem txheej txheem ntawm cov hniav txhuas phaj.
Tam sim no tsis muaj ntau tshaj peb txoj hauv kev tiv thaiv saum npoo ntawm cov ntawv txhuas txhuas:
(1) Anodizing, aluminium alloy qhov rooj thiab lub qhov rais tau qhia txog xyoo 1950, thiab nws tseem yog ib qho kev kho mob saum npoo rau txhuas qhov rooj thiab qhov rai thiab kho kom zoo nkauj txhuas vaj huam sib luag;
(2) Electrophoresis acrylic resin tom qab anodic oxidation tau ua lag luam hauv Nyij Pooj xyoo 1960, thiab siv tau nyob hauv Europe thaum xyoo 1970, thiab tam sim no feem ntau yog siv hauv Asia. Tam sim no, thev naus laus zis tau tsim los ntawm cov yeeb yaj kiab ci ntsa iab mus rau matte pob tshab zaj duab xis thiab xim zaj duab xis. Cov hom tau dhau los ua ntau hom, thiab kev tswj kev lag luam thiab cov khoom lag luam zoo kuj ruaj khov.
(3) Electrostatic txau tom qab kev hloov tshuaj lom neeg suav nrog electrostatic hmoov txau thiab electrostatic kua txau. Electrostatic kua txau rau cov tshuaj fluorocarbon resins tau tsim kev lag luam hauv Tebchaws Asmeskas xyoo 1960. Lub tshuab electrostatic hmoov txau thermosetting polyester txheej tau ua lag luam nyob hauv Tebchaws Europe thaum xyoo 1960, thiab nws tseem yog hom kev kho mob saum npoo av hauv cov tebchaws European. Niaj hnub no, tib-anodized aluminium qhov rooj thiab qhov rai tau raug txo qis hauv kev ua lag luam nyeg thiab txawv teb chaws. Nyiv nyiam hluav taws xob txheej electrophoretic. Dawb electrophoretic txheej tau tsim sai heev thiab tau thov nyob hauv Europe. Electrostatic hmoov txau tau dhau los ua cov txheej txheem kho saum npoo av hauv Tebchaws Europe thiab Asmeskas vim nws cov xim sib txawv, kev tswj kom yooj yim, kev tiv thaiv ib puag ncig, thiab kev ua haujlwm zoo heev. Nyob rau hauv xyoo tas los, electrostatic hmoov txheej ua lag luam kuj tau nthuav dav hauv kuv lub teb chaws.
(4) Xim xim: feem ntau fluorocarbon txau. Cov kev kho mob ua ntej txau cov phaj txhuas yog qhov tseem ceeb dua. Passivation kev kho mob yog qhov yuav tsum ua kom ntseeg tau tias cov xim thiab txhuas phaj yog sib koom ua ke. Kev siv raug yog tias daim ntaub thaiv phab ntsa txhuas phaj yog nto kho nyob rau hauv txoj kev no.
