Lub rauj down-the-qhov rauj yog cov cuab yeej siv tshuab uas siv cov roj cua siab los ua cov ntaub ntawv hlau rau hauv ib qho duab. Thaum ua tiav nrog rauj down-lub-qhov rauj, txheej txheej feem ntau yog siv rau saum npoo ntawm cov khoom siv hlau. Lub luag haujlwm ntawm txheej txheej muaj xws li cov hauv qab no:
Txo kev sib txhuam thiab hnav: Thaum lub rauj down-lub-qhov yog ua hauj lwm, cov ntaub ntawv hlau yuav los rau hauv kev sib cuag nrog ntau yam ntawm cov khoom,
ua rau muaj kev sib txhuam thiab hnav. Cov txheej txheej tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm cov khoom siv hlau, txo qhov kev sib cuag ncaj qha ntawm cov hlau nto, thiab yog li txo kev sib txhuam thiab hnav.
Txhim kho hardness thiab hnav tsis kam: Txheej tuaj yeem txhim kho qhov nyuaj thiab hnav tsis kam ntawm cov khoom siv hlau, ua rau lawv muaj zog thiab ruaj khov dua.
Txhim kho qhov zoo: Cov txheej tuaj yeem sau cov qhov me me thiab cov kab nrib pleb ntawm qhov chaw ntawm cov khoom siv hlau, yog li txhim kho qhov zoo thiab ua rau cov khoom siv hlau ua tau zoo dua qub thiab zoo dua qub.
Anti-corrosion: Qee cov txheej txheem kuj tuaj yeem tiv thaiv oxidation thiab corrosion ntawm cov ntaub ntawv hlau, ua rau lawv lub neej ua haujlwm thiab ua haujlwm ntev.
Nyob rau hauv luv luv, lub txheej plays lub luag hauj lwm tseem ceeb heev nyob rau hauv kev ua ntawm down-lub-qhov hammers, uas yuav txhim khu kev ua tau zoo thiab kev pab cuam lub neej ntawm cov ntaub ntawv hlau.
