Tam sim no, muaj ntau yam hlau thiab ntoo hluav taws- ntsuas qhov rooj ntawm lub khw, nrog rau cov nqi sib txawv. Qee lub lag luam uas tsis ncaj ncees tau muag cov khoom lag luam tsis zoo raws li qib siab - cov khoom kawg kom tau txais txiaj ntsig ntau tshaj plaws, dag ntxias cov neeg siv khoom uas tsis paub txog steel thiab ntoo hluav taws - ntsuas qhov rooj. Qhov no cuam tshuam loj heev rau kev lag luam kev txiav txim.
Yog li ntawd, cov neeg siv khoom yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no ua ntej yuav cov hlau thiab ntoo hluav taws- cov qhov rooj:
Trim cov ntaub ntawv: Tam sim no, cov ntaub ntawv trim ntawm kev ua lag luam feem ntau muab faib ua peb pawg:
1. Ntoo-plastic composite trim: Cov ntoo- cov khoom siv yas sib xyaw yog npog nrog zaj duab xis (PVC) lossis ntawv pleev xim. Vim cov txheej txheem lamination siv rau saum npoo, cov veneer tau yooj yim sib cais los ntawm cov khoom siv hauv paus thaum siv, ua rau blistering ntawm txheej txheej thiab hmoov ntawm cov ntoo - cov khoom siv yas sib xyaw;
2. Steel-plastic composite trim: Cov hlau- cov khoom siv yas sib xyaw yog npog nrog zaj duab xis (PVC). Vim cov txheej txheem lamination siv rau ntawm qhov chaw, veneer yooj yim cais tawm ntawm cov khoom siv thaum siv, ua rau blistering ntawm txheej txheej.
Cov txheej txheem kev kho qhov rooj ntawm qhov rooj: Hloov luam ntawv thiab ci txheej txheem: Cov phaj hlau tau txais phosphating kua los tiv thaiv- kev kho corrosion, hauv qab ntawm cov phaj steel yog hmoov-coated thiab ci, thiab ntoo grain yog rhuab thiab xa mus rau xim nyob rau hauv qab ntawm lub phaj steel, ces ci dua. Qhov saum npoo siv tsheb - qib ci xim tshuab.
Lub steel phaj thickness yog qhov feem ntau qhia txog cov khoom zoo. Vim muaj ntau haiv neeg ntawm kev lag luam tus nqi, steel phaj thickness kuj txawv. Yuav kom ua tiav cov khoom tiaj tus, du, thiab ruaj khov, cov phaj steel thickness yuav tsum yog 0.5 hli lossis ntau dua. Tsuas yog tom qab ntawd nws tuaj yeem ua tiav qhov cuam tshuam zoo thiab tiv thaiv - kev sib tsoo.
