Kev faib cov khoom siv iav
Ib hom yog iav ntawv, feem ntau yog siv rau qhov chaw uas yuav tsum tau teeb pom kev zoo hauv kev kho kom zoo nkauj, xws li iav tiaj tus, embossed iav, frosted iav, coated iav, engraved iav, tempered iav thiab lwm yam, uas muaj peev xwm xaiv tau raws li qhov yuav tsum tau ntawm qhov sib txawv thiab hniav cuam tshuam.
Lwm hom yog iav cib, feem ntau yog siv rau iav partitions, iav phab ntsa, thiab lwm yam dej num, feem ntau hollow iav cib. Nws tuaj yeem muab faib ua ob hom: ib chav chamber thiab ob chav chamber, nrog rau ntau yam tshwj xeeb xws li square bricks thiab rectangular bricks. Nws cov duab saum npoo kuj yog nplua nuj heev thiab tuaj yeem xaiv thiab siv raws li kev xav tau kho kom zoo nkauj.
iav fiber luv ntu
1. Kev tshuaj xyuas cov ntawv iav. Cov tsos zoo yog feem ntau kuaj xyuas qhov flatness, saib xyuas qhov tsis zoo xws li npuas, suav nrog, khawb, kab, thiab pos huab. Cov iav nrog xws li qhov tsis xws luag yuav deform thaum siv, txo nws cov pob tshab, txhua yam muaj zog, thiab thermal stability. Yog li ntawd, nws tsis haum rau siv hauv engineering. Raws li iav yog cov khoom pob tshab, nws qhov zoo tuaj yeem pom tau yooj yim los ntawm kev kuaj pom thaum xaiv.
2. Kev tshuaj xyuas cov khoom siv iav. Ntxiv nrog rau kev kuaj xyuas raws li qhov yuav tsum tau ua ntawm cov iav tiaj tus, kev ua haujlwm zoo yuav tsum tau kuaj xyuas kom ntseeg tau tias cov kev qhia tshwj xeeb, qhov ntev, kev ua haujlwm raug, thiab cov qauv pom tseeb raws li qhov yuav tsum tau ua. Nyob rau tib lub sijhawm, yuav tsum tsis muaj qhov tsis xws luag ntawm cov npoo.
3. Qhov zoo ntawm cov iav hollow iav yuav tsum tsis txhob muaj kab nrib pleb, opaque unmelted cov ntaub ntawv yuav tsum tsis txhob raug tso cai nyob rau hauv lub iav lub cev, thiab tsis zoo welding thiab bonding ntawm ob lub khob iav yuav tsum tsis pub. Visually, lub cev cib yuav tsum tsis txhob muaj ripples, npuas, los yog txheej kab txaij tshwm sim los ntawm heterogeneity nyob rau hauv lub khob iav. Lub concave nto ntawm qhov loj ntawm lub iav cib yuav tsum tsawg tshaj li 1 millimeters, thiab convex nto yuav tsum tsawg tshaj li 2 millimeters. Qhov hnyav yuav tsum ua tau raws li cov qauv zoo, thiab yuav tsum tsis muaj qhov tsis zoo xws li kev sib tsoo ntawm qhov chaw, qhov chaw, burrs, thiab lwm yam. Lub kaum sab xis yuav tsum yog square.
