Teeb Meem Zoo
Cov teeb meem zoo ntawm cov kav hlau me me yog cov hom tsis xws luag, feem ntau yog qhov tshwm sim tsis muaj qhov ntev, ua rau cov khoom siv tsis raug, thiab lwm yam.
1. Tsis muaj tseeb qhov ntev
Thaum lub sijhawm cov txheej txheem ntau lawm, vim muaj cov txheej txheem tswj tsis txaus lossis cov khoom siv tsis muaj khoom siv, cov kev sib txawv loj hauv cov yeeb nkab loj tuaj yeem tshwm sim.
2. Tshuaj lom neeg sib xyaw ua tsis tau raws li tus qauv
Kev ua yeeb yam ntawm cov kav hlau me hlau yog sib cuam tshuam nrog cov tshuaj lom neeg muaj pes tsawg leeg. Tsis khov muaj pes tsawg leeg yuav cuam tshuam ncaj qha cuam tshuam rau cov khoom siv tshuab ntawm cov yeeb nkab.
3. Cov khoom siv tsis zoo
Xws li muaj lub zog tensile, nruj heev thiab lwm yam teeb meem, uas yuav tshwm sim vim kev kho mob kub lossis kev tswj cov lax thaum cov txheej txheem.
Cov teeb meem zoo feem ntau yog tshwm sim los ntawm kev xaiv tsis raug cai ntawm cov ntaub ntawv raw, kev ua haujlwm hauv cov txheej txheem tsim khoom thiab lwm yam. Yuav daws lawv li cas?
Txog cov teeb meem zoo ntawm cov kav dej hlau me me, kev tiv thaiv thiab kev tswj hwm yuav tsum tau nqa los ntawm kev xaiv zoo, nruj kev tswj hwm cov kev txuas tsim khoom thiab kev tshawb nrhiav cov qauv tsim nyog.
Thaum muaj teeb meem zoo, kev ntsuas yuav tsum tau ua kom sai li sai tau los kho thiab ua kom cov ncauj lus qhia ntxaws ntxaws rau txhua qhov txuas, thiab xyuas kom meej tias cov khoom raws cov qauv. Kho kho kom haum thiab cov cuab yeej ntsuas kom ntseeg tau tias txhua qhov tsis muaj nyob hauv cov txheej txheem ntau lawm.
Nto qhov tsis xws luag

2. Kuaj
Thaum lub sijhawm ua lossis cov txheej txheem tuav, kos yuav tshwm sim nyob rau saum npoo ntawm cov yeeb nkab steel, uas yuav dhau los ua qhov pib ntawm corrosion.
Cov khoom tsis zoo rau saum npoo yog feem ntau tshwm sim los ntawm kev ua haujlwm tsis zoo, ua haujlwm tsis raug thaum lub sijhawm tsim khoom, thiab lwm yam yuav daws lawv?
1. Rau saum npoo ib qho tsis xws luag ntawm cov kav hlau me hlau
Thaum lub sijhawm ua tiav, kev saib xyuas yuav tsum tau them nyiaj rau kev kho kom huv thiab kev tiv thaiv kev tiv thaiv kev kho kom zoo thiab tsis txhob muaj xeb thiab tsis muaj xeb thiab lwm yam teeb meem.
2. Rau cov khawb, oxidation thiab lwm yam teeb meem
