(1) Zoo hnav ua haujlwm
Qhov paug ntawm qhov chaw thiab qhov tseeb ntawm qhov chaw yog ncaj qha ntsig txog kev hnyav ntawm qhov chaw tuag. Piv txwv, tsim cov thermosetting reagents thiab cov yas nrog cov iav fiber, nws yuav tsum tau tuag kom muaj kev sib tw ua rau siab. Kev nyuaj siab ntawm kev ploj tuag yog siab, yog li nws muaj kev coj zoo thiab kev ua haujlwm ntev.
(2) Ua kom tawv nqaij zoo
Ntxiv rau qhov chaw siab tawv, qhov tuag kuj tseem yuav tsum tau muaj zog txaus, xws li cov pwm txhaj tshuaj tiv thaiv lub siab loj txhaj thiab clamping siab, yog li cov tub ntxhais lub zog ntawm tus tuag yuav tsum tau muab rau hauv tus account, uas yog, lub hlau yog yuav tsum muaj zoo hardenability
(3) Kev tiv thaiv zoo corrosion
Plastics thiab additives muaj cov tshuaj tua hluavtaws los ntawm cov hlau (xws li PVC rau xov tooj thiab pob qij txha thiab pob zeb nrog cov nplaim hluavtaws), ces yuav tsum xaiv lossis kho chromium thiab nickel plating rau ntawm cov kab noj hniav.
(4) Kev ua haujlwm zoo
Tom qab cov cua sov kho, tus deformation me thiab kev ua haujlwm zoo, uas tuaj yeem ua kom cov duab thiab qhov tseeb ntawm cov tuag. Nyob rau tib lub sijhawm, vim hais tias qhov zoo ntawm qhov tuag qhov chaw feem ntau yog qhov nyuaj, kev ua tom qab quenching nyuaj, los yog nws yog tsis yooj yim sua kom txhua tus txheej txheem, yog thaum xaiv cov khoom tuag, cov hlau nrog me me deformation tom qab cua sov kev kho mob yuav tsum tau xaiv kom deb li deb tau. Qee qhov tuag tau qhov teebmeem ua ntej thiab tom qab ntawd. Txawm li cas los xij, kev ua kom tawv nqaij tom qab ua pa taws thiab npau taws yuav tsum tsis txhob siab tshaj 300 HB. Nws lub homphiaj yog los pab txhawb kev ua haujlwm thiab kev ntsuas. Nyob rau hauv cov ntaub ntawv no, cov ntaub ntawv deformation tom qab cua sov kev kho mob tsis tseem ceeb, txawm tias nws yog loj, vim hais tias semi-tiav roughcast tom qab roughing tau kom tiav.
(5) Kev sib tw ua kom zoo
Qhov feem ntau yuav tsum muaj qhov zoo thiab muaj zog, yog li cov kab noj tuag yuav tsum tau zoo zoo, yog li xaiv cov hlau yuav tsum tsis muaj cov ntxhib impurities thiab pore, thiab lwm yam. Hlau pwm yuav tsum muaj qhov zoo nkauj ua kev ua tiav, xws li tsheb thiab khoom siv hluav taws xob hauv tsev.
Muaj qee qhov sib txawv ntawm cov saum toj no ua yeeb yam, xws li kev ua lag luam, hnav kev ua haujlwm, kev xeb ntawm kev qis thiab ua li ntawd. Vim li no, kev saib xyuas zoo yuav tsum tau ua raws li txoj cai siv thiab kev tsim ntawm cov neeg tuag.
