Xaiv lub txheej kav

Tsis muaj high-zoo phwj system muab ib tug txaus theem ntawm kev nplij siab, niaj hnub tsev yog tsuas tsim nyog. Tab sis, yog hais tias koj txuag tau nyiaj on nws siv, nws tau muab nws tus kheej nrog ib tug tag nrho puag ntawm cov teeb meem, thiaj li hais tias tag nrho cov ntsiab ntawm cov kua system yuav tsum muaj zoo zoo.

Kev saib xyuas yuav tsum tau xaiv nyob sab nraum dej kav. Qhov zoo ces, niaj hnub kev lag luam yuav muab ib tug lossis loj npaum li cas ntawm high-zoo thiab cov khoom ruaj ruaj, yog li ntawd nws tsis yog li ntawd tsis yooj yim.

Nyob rau hauv loj kav dej phwj yeeb nkab tshuab siv tau los ntawm asbestos MAAs, ua kev reinforced, cam khwb cia hlau los yog yas. Txawm li cas los, tsis tau raws li nyuam qhuav kav ua los ntawm asbestos maas los cam khwb cia hlau, vim hais tias lawv raug nqi ntau dua tsis correlate nrog rau kev kawm. Nyob rau hauv tas li ntawd, cov ubiquitous lately polymeric txheej kav yog yooj yim npaum li kom muaj thiab nruab.

Nyob rau hauv kev, lub yav tas thiaj li nrov ntev los no, cov kav dej ua los ntawm cov hlau yog pawg loj disadvantages. Cov feem cuab kev yog cov neeg pluag xeb kuj. Nws yog ntseeg hais tias nyob rau hauv cia li ib lub xyoo, tus qauv yeeb nkab steel yuav thinner los ntawm tsawg kawg yog ib millimeter. Yog hais tias peb coj mus rau hauv tus account lub hnyav los ntawm stray currents thiab tau cov yam ntxwv ntawm cov av nyob rau hauv ib co chaw ntawm lub neej ntawm tej ntaub ntawv yog tsis ntau tshaj li tsib los sis rau xyoo. Qhov no yeeb nkab sewerage (lwm) yog tsis tsuas kim, tab sis kuj tsis laij nws cov high nqi.

Thiab yog li ntawd thaum xaiv cov tsim cov ntaub ntawv uas yuav tsum coj mus rau hauv tus account ob peb tseem ceeb tsis:

• Zog yam ntxwv;
• durability;
• muaj peev xwm tso tau raug txhoj puab heev tshuaj kev kawm;
• kuj kub extremes.

Xav txog cov neeg nyob sab nraum dej kav dej lom zem ntau raws li tag nrho cov saum toj no yuav tsum.

asbestos ntau ntau yam

Cov khaub-ncaws nyias thiab check kav ua los ntawm Portland MAAs thiab asbestos. Muab lub smoothness ntawm lub puab nto, lawv tsis daig heev heev. Tu siab, ib tug tseem ceeb disadvantage yog ib tug me ntsis ntau zog fragility, thiab yog li ntawd ua hauj lwm nrog xws li kav xav tau raws li ua tib zoo raws li sai tau.

polymeric qauv

Cov sab nraud kav dej uas feem ntau siv nyob rau hauv xyoo tsis ntev los. Lawv yog cov heev check, muaj tsawg luj, ib qho yooj yim rau nruab thiab tsis yog cov nquag mus clogging. Lub disadvantage yog hais tias rau lawv cov installation yog feem ntau tsim nyog los siv ib tug tshwj xeeb vuam tshuab uas yuav tsum tau hluav taws xob nyob rau hauv lub vaj tse nyob rau hauv kev tsim kho. Txawm li cas los, muab lawv cov uas tsis muaj nqi thiab muaj kev kawm siab, cov "irregularities" tau yooj yim txais.

Cam khwb cia hlau kav

Tsis muaj teeb meem zoo li cas polymeric cov ntaub ntawv, tab sis lawv cov neeg kho tshuab zog thiab kuj rau siab kub yog neeg pluag. Cam khwb cia hlau kuj muaj ib tug high cia siab rau thiab thiav, raws li zoo raws li zoo kuj mus txhoj puab heev tshuaj tej kev kawm. Nws tsis muaj peev xwm nyob rau hauv hnyav, raws li zoo raws li nyob rau hauv kev twb kev txuas complexity.

Yog li, cov lim dej yeeb nkab sab nraum (tus nqi uas nyob rau ntawm lub hom thiab chaw tsim tshuaj paus), koj yuav tsum tau xaiv ntse ntsuav, ntawm lawv xav tau kev pab.
