Lub koom haum sab hauv ntawm ib feem ntawm cov tooj liab tooj liab tseem tseem nruj, thiab tsis muaj qhov xwm txheej xoob dhau. Nws tsis muaj qhov hws thiab trachoma, yog li cov tooj liab tooj liab tseem tseem ci los ntawm qhov tsos, thiab nws cov xim yog qhov tshwj xeeb. Thiab qhov tseem ceeb tshaj plaws yog tias nws cov tawv tawv yog qhov siab.
2. Corrosion: Lwm qhov tshwj xeeb ntawm lub tes tsho tooj liab yog kev tiv thaiv corrosion thiab kev ua haujlwm zoo corrosion. Nws tsuas yog siv hauv huab cua thiab dej tshiab, vim tias ib puag ncig zoo ib yam. Hauv cov txheej txheem ntawm kev siv tooj liab tooj liab, nws feem ntau tsis yooj yim rau txeeb. Kev tiv thaiv kev xeb ntawm cov tooj liab tooj liab feem ntau cuam tshuam rau qee yam tshuaj lom neeg, xws li: dilute sulfuric acid, hydrochloric acid thiab fatty acids, thiab lwm yam, yog li kev txhim kho corrosion ntawm tooj liab tooj liab yog qhov zoo heev, vim li cas nws thiaj tsis tshwm feem ntau yog vim nws tus yam ntxwv thiab nws qhov ua tau zoo kuj zoo ib yam. Nws tseem tuaj yeem ua haujlwm ib txwm txawm tias tsis muaj cov roj nplua nyeem thiab cov dej zoo, thiab nws cov zawv zawg thiab nws tus kheej lub zog tseem tuaj yeem tswj tau. .
3. Lub peev xwm ua kom siab: Lub peev txheej ntawm lub tes tsho tooj liab kuj tseem zoo. Nws qhov siab yog qhov loj heev, thiab nws tuaj yeem tiv taus sab siab ntawm cov kabmob zoo. Lub tes tsho tooj liab kuj tseem tuaj yeem ua haujlwm nyob rau hauv siab load siab. Nws yog qhov tsim nyog rau kev siv Tsawg nrawm thiab lub sijhawm hnyav.
Muaj ntau lwm txoj haujlwm ntawm lub tes tsho, thiab nws yooj yim rau tib neeg kho nws, ua kom yooj yim rau cov qauv, thiab hauv qee qhov, lub tes tsho tooj liab tuaj yeem ua rau qee qhov yuam kev hauv lub tshuab tsim. Yog li ntawd, lub luag haujlwm ntawm lub tes tsho tooj liab tseem muaj ntau heev, thiab qhov no yog nws qhov zoo.
