Tooj liab qab ua ib qho kev hloov pauv me me hauv peb lub neej txhua hnub. Tooj liab tuaj yeem siv los thauj dej, lub zog hauv Is Taws Nem, txhim kho cov zaub mov noj, thiab xa khoom siv rau tsheb. Tooj liab yog lub zog uas tsis pom kev sib txuas, yooj yim, thiab kev nyab xeeb, ua kom peb txhua hnub zoo dua vim nws.
Ruaj khov thiab muaj kev nyab xeeb coppper yeeb tshuaj yeeb
Tooj liab yog tshuaj tsis ruaj khov, ua ke txias, kub, corrosion thiab hluav taws xob tsis kam lees tus capsius) hauv ib chav tsev, cia nws siv rau ntau lub sijhawm ntawm ntau qhov chaw ib puag ncig. Qhov kev pabcuam lub neej ntawm cov yeeb nkab tooj liab yuav tau ntev npaum li lub tsev, lossis ntev dua, PEKING UNION CLUCKING CEM tom qab ntau tshaj 70 xyoo, tseem yog kev ua tau zoo.
Nws tuaj yeem pom tau tias cov yeeb nkab tooj liab tau raug ntsuas ntau tshaj li ib puas xyoo thiab cov kev paub dhau los. Tooj liab yeeb muaj kev nyab xeeb thiab txhim khu kev qha. Tooj liab yeeb sib xyaw ua ke cov khoom siv hlau thiab cov yeeb nkab uas tsis yog-hlau. Nws yog qhov nyuaj dua cov yeeb nkab yas, muaj lub zog siab ntawm cov hlau dav dav (txias-kos tooj liab yeeb nkab lub zog thiab tib phab ntsa tuab ntawm cov yeeb nkab steel); Nws yog qhov yooj yim dua rau khoov dua li cov hlau dav dav, kev ua kom muaj zog thiab kev tawm tsam siab, cuam tshuam thiab tiv thaiv khov thiab nthuav dav.
Tooj liab raj tuaj yeem tiv taus loj loj sib txawv
Txoj kab nthuav dav ntawm cigefficient ntawm tooj liab yeeb yog heev me me, yog 1/10 ntawm cov yeeb nkab yas, tuaj yeem tiv taus kev qaug zog. Nws yuav tsis tau ua tiav kev nthuav dav ntau dhau thiab kev txhawb nqa thaum hloov qhov kub thiab txias thiab ua rau muaj kev ntxhov siab tsis muaj zog.
Cov yam ntxwv no ua rau cov copper yeeb nyob rau hauv cov chaw txias ntawm daim ntawv thov yog qhov zoo heev. Cov chaw no muaj qhov sib txawv loj ntawm thaum sawv ntxov thiab yav tsaus ntuj, txoj kab nthuav dav, yooj yim heev los tsim kev ntxhov siab ntawm kev ntxhov siab. Qee qhov kev thov uas -20}} tsis muaj qhov tsis txaus, tab sis hauv kev ua haujlwm tsis muaj qhov tseeb, thiab kev ua haujlwm ntawm lub zog coppil ntawm {}}}}} degrees thiab chav kub yog tib yam.
