Yog tias tsis muaj lub kav dej zoo, nws tsuas yog tsis muaj tseeb los muab kev nplij siab txaus rau lub tsev niaj hnub. Tab sis yog tias koj txuag ntawm lub tsev, koj muab koj tus kheej nrog tag nrho cov khib nyiab ntawm cov teeb meem, yog li tag nrho cov ntsiab lus ntawm cov dej ntws yuav tsum yog qhov zoo tshaj plaws.
Cov kav dej phwj sab nraud yuav tsum tau xaiv tshwj xeeb yog ua tib zoo. Hmoov zoo, kev lag luam niaj hnub tuaj yeem muab cov ntaub ntawv zoo thiab ruaj khov, yog li qhov no tsis nyuaj.
Asbestos-cement, cov pob zeb muaj zog, cam khwb cia hlau lossis cov kav dej polymer tuaj yeem siv rau hauv cov kav dej loj. Txawm li cas los xij, tsis ntev los no cov kav dej ua los ntawm asbestos cement lossis cam khwb cia hlau tsis tau pom, vim tias lawv cov nqi yog me ntsis cuam tshuam nrog kev ua haujlwm. Tsis tas li ntawd, tsis ntev los no cov kav dej polymer sab nraum zoov tau yooj yim dua los tswj thiab nruab.
Tshwj xeeb, tau nrov heev tsis ntev los no, cov kav hlau hlau muaj ib pawg lojua tsis tau. Qhov pom tseeb tshaj plaws yog qhov tsis zoo corrosion kuj. Nws ntseeg tau tias nyob rau hauv ib xyoos nkaus xwb tus qauv steel yeeb nkab yuav thinner los ntawm tsawg kawg yog ib millimeter. Yog hais tias peb coj mus rau hauv tus account qhov hnyav ntawm stray tam sim no thiab cov yam ntxwv ntawm cov av, ces nyob rau hauv qee qhov chaw, lub neej kev pab cuam ntawm cov ntaub ntawv no tsis pub tshaj tsib mus rau rau xyoo. Xws li cov kav dej phwj (sab nrauv) tsis yog kim xwb, tab sis kuj tsis ua rau nws tus nqi siab.
Thiab yog li ntawd, thaum xaiv cov khoom tsim nyog tshaj plaws, ob peb yam tseem ceeb yuav tsum raug coj mus rau hauv tus account ib zaug:
- tus yam ntxwv muaj zog;
- durability;
- muaj peev xwm tiv taus kev cuam tshuam rau cov tshuaj lom neeg ib puag ncig;
- tiv taus kub heev.
Cia peb xav txog cov kav dej tawm sab nraum zoov uas ua tau raws li txhua qhov kev xav tau saum toj no.
Asbestos-cement ntau yam
Cov kav dej sib sib zog nqus thiab ruaj khov yog tsim los ntawm asbestos thiab Portland cement. Muab qhov smoothness ntawm lawv sab hauv, lawv tsis tau clogged ntau dhau lawm. Hmoov tsis zoo, lawv qhov teeb meem tseem ceeb yog lawv qhov tsis txaus ntseeg me ntsis, thiab yog li nws yuav tsum tau ua haujlwm nrog cov kav dej kom zoo li sai tau.
polymer qauv
Cov kav dej tawm sab nraum zoov no tau siv ntau tshaj plaws tsis ntev los no. Lawv yog cov ruaj heev, lub teeb nyob rau hauv qhov hnyav, yooj yim rau mount thiab yuav luag indestructible.thaiv. Qhov tsis zoo yog tias rau lawv qhov kev txhim kho kom raug nws yog feem ntau yuav tsum tau siv cov tshuab tshwj xeeb welded, uas yuav tsum muaj hluav taws xob nyob ntawm qhov chaw tsim. Txawm li cas los xij, muab lawv tus nqi qis thiab kev ua haujlwm siab, cov "roughness" tuaj yeem sib haum xeeb tau yooj yim.
cam khwb cia hlau kav
Txawm hais tias cov ntaub ntawv polymer zoo npaum li cas, lawv cov khoom siv dag zog thiab kev tiv thaiv kom siab kub tawm ntau yam uas xav tau. Cam khwb cia hlau, ntawm qhov tod tes, yog qhov txawv los ntawm kev ntseeg siab thiab kev ua haujlwm ntev, nrog rau kev ua haujlwm zoo rau cov tshuaj lom neeg ib puag ncig. Nws qhov tsis zoo yog qhov hnyav, nrog rau qhov nyuaj ntawm kev sib txuas.
Yog li, cov kav dej tawm sab nraum zoov (tus nqi uas nyob ntawm lawv hom thiab cov chaw tsim khoom) yuav tsum tau xaiv kom zoo, tsom ntsoov rau koj cov kev xav tau.
