Nyob hauv lub ntiaj teb niaj hnub no, thaum lub sij hawm tsim kho thiab kev tsim kho vaj tse, cov lus nug tshwm sim ntawm kev hloov kho lub tswv yim ntawm kev khaws cua sov thiab kev ncaj ncees ntawm kev sib txuas lus. Vim qhov nce ntawm cov nqi hluav taws xob tas li, cov neeg siv khoom feem ntau raug yuam kom txuag. Tab sis tsis tsuas yog qhov tseem ceeb no ua rau peb xav txog kev khaws cov cua sov. Kev ntsuas ib puag ncig kuj tseem ceeb. Lub ntsiab kev txuag hluav taws xob yog cov ntaub ntawv insulating. Kev tsim tshuab ntawm cov khoom zoo li no tso cai rau koj los tiv thaiv thiab tswj cov ntsuas kub tsis muaj kev puas tsuaj rau lwm tus. Thaum ua cov kev ntsuas rwb thaiv tsev, ntau dua 40% ntawm lub zog tuaj yeem txuag tau thiab cov qauv hlau ntawm cov kav dej tuaj yeem tiv thaiv corrosion.
Cov yam ntxwv dav dav
Cov khoom siv insulating hauv qab no yog qhov txawv:
- Lub tsev insulators uas siv rau rwb thaiv tsev ntawm phab ntsa, qab nthab, ru tsev.
- Engineering insulators tsim los rau thermal rwb thaiv tsev ntawm tes hauj lwm,pipelines.
Muaj cov yam ntxwv ntawm cov ntaub ntawv insulating uas tam sim no tsis hais hom twg. Lawv yuav tsum tsis muaj dej, txwv tsis pub cov dej noo yuav rhuav tshem cov khoom tiv thaiv thiab cuam tshuam nws txoj haujlwm. Thaum cuam tshuam nrog ib puag ncig, lawv khaws lawv txoj kev ncaj ncees, tuaj yeem tiv taus qhov kub thiab txias, tshuaj lom neeg sib xyaw, thiab kev puas tsuaj.
Tus yam ntxwv tseem ceeb yog lub peev xwm ntawm kev rwb thaiv tsev tsis cuam tshuam rau cov khoom tiv thaiv. Thiab qhov taw qhia kawg yog profitability. Qhov zoo ntawm cov ntaub ntawv yuav tsum phim tus nqi. Nyob ntawm hom thiab lub hom phiaj ntawm rwb thaiv tsev, lawv muaj cov yam ntxwv ntxiv.
Kev faib tawm
Raws li lawv cov yam ntxwv, cov ntaub ntawv insulating tau muab faib ua:
- thermal rwb thaiv tsev;
- soundproof;
- dej pov thawj;
- windproof;
- sua thiab dej pov thawj.
Cov ntaub ntawv thaiv phab ntsa
Txhawm rau tiv thaiv lub tsev, nws yog qhov tsim nyog los tiv thaiv nws ntawm qhov txias thiab noo noo. Cov khoom siv rwb thaiv tsev tshiab tiam tshiab tuaj yeem ua qhov no yam tsis ua rau koj noj qab haus huv. Cov khoom siv muaj ntau haiv neeg - lawv tuaj yeem yog fiberglass, ntxhia wool, txiv qaub-silica thiab ua npuas ncauj yas. Lawv nyob rau hauv daim ntawv ntawm cov blocks, daim hlau los yog yob.
Ntawm cov cua sov
Cov ntaub ntawv thaiv phab ntsa muaj lawv tus kheej cov qauv thiab cov cai. Ntxiv nrog rau cov yam ntxwv tseem ceeb, ib qho tseem ceeb tshwj xeeb yuav tsum tau muab sau tseg - qhov no yogflammability.
Muaj 3 hom kev tiv thaiv hluav taws:
- flammable (A1);
- flammable(B1);
- flammable (B3).
Yog li, thaum yuav, ua tib zoo nyeem cov ntawv sau ntawm lub pob. Cov chaw tsim khoom yuav tsum tau qhia muaj cov ntaub ntawv tag nrho txog cov khoom. Yog li, yog tias koj chav tsis muaj cov cuab yeej tua hluav taws tshwj xeeb, koj tuaj yeem siv cov ntaub ntawv A1 pab pawg. Cov no muaj xws li ntxhia fiber rwb thaiv tsev. Yog tias lub tsev muaj kev tiv thaiv tsawg kawg nkaus tiv thaiv hluav taws thiab koj paub tseeb tias qhov tshwm sim ntawm cov khoom siv cua sov siab tshaj 100 degrees tsis suav nrog, koj tuaj yeem siv cov ntaub ntawv ntawm pawg B1. Cov insulators ntawm pab pawg no yog ua los ntawm nruj polystyrene ua npuas ncauj. Kev siv cov ntaub ntawv ntawm pawg B3 hauv kev tsim kho yog txwv.
Cov khoom siv rau phab ntsa rwb thaiv tsev yuav tsum muaj cov cuab yeej tseem ceeb - kom nws cov duab. Qhov no yog qhov tsim nyog kom lub zuag qhia tag nrho tsis deteriorate. Yog tias cov khoom pib hloov pauv, nws yuav hloov nws txoj haujlwm qub thiab tsis ua nws txoj haujlwm. Tab sis tsis muaj chaw tsim khoom tuaj yeem lav tias cov khoom yuav coj li cas tom qab lub sijhawm ntev. Yog li ntawd, coj qhov tseem ceeb no rau hauv tus account thaum txhim kho thiab txuas cov insulator raws li.
Thermal conductivity yog lwm qhov taw qhia uas qhia txog kev rwb thaiv tsev. Cov ntaub ntawv vov tsev muaj qhov siab tshaj plaws. Cov uas muaj nruab nrab thiab qis yog haum rau thav duab.
Waterproofing yog qhov tseem ceeb tshaj plaws thaum insulating phab ntsa. Vim yogQhov kub hloov pauv tuaj yeem khaws cov dej noo. Cov ntaub ntawv niaj hnub no tsis tsuas yog tshem tawm xwb, tab sis kuj tsim kom zoo microclimate hauv chav.
yeeb nkab rwb thaiv tsev
Qhov teeb meem loj tshaj plaws rau cov kav dej yog hlau corrosion. Txij li thaum noo noo feem ntau accumulates nyob rau saum npoo ntawm lub raj xa dej, nws pib xeb, nws txoj kev ncaj ncees raug ua txhaum thiab ua tsis tiav. Cov txheej txheem no tuaj yeem tshwm sim rau ntau yam laj thawj. Piv txwv li, vim muaj kev cuam tshuam ntawm hluav taws xob tam sim no. Nws tseem yuav tsum tau insulate cov kav dej kub vim muaj cua sov thaum lub sij hawm thauj mus los.
Cov khoom siv rwb thaiv tsev rau cov kav dej feem ntau muaj cov txheej txheem nyias nyias uas tiv thaiv cov hlau los ntawm cov dej noo, cua, thiab tam sim no. Yog tias tsim nyog, txhawm rau khaws cov cua sov hauv cov kav dej, lawv tau siv rau hauv ntau txheej, piv txwv li, los ntawm cov khoom sib txawv polymeric thiab bituminous.
Yam yeeb nkab rwb thaiv tsev
Xyaum ib txwm thiab txhim kho hom kev sib cais. Cov tom kawg raug rau cov kav dej uas tau muab tso rau hauv av nrog cov ntsiab lus siab ntawm cov tshuaj. Muab hais tias cov yeeb nkab txoj kab uas hla yog ntau tshaj 1 m. Rau rwb thaiv tsev, bitumen thiab polymer cov ntaub ntawv, iav thiab kua roj vanish txheej thiab lwm yam yog siv.
Vim qhov xav tau kom koj lub tsev sov so thiab ua kom muaj kev sib txuas lus ntev li ntev tau, nws yog qhov tsim nyog los siv cov ntaub ntawv insulating. Ua tsaug rau ntau yam, koj tuaj yeem khaws txhua yam yooj yimkoj xav tau, raws li koj xav tau thiab cov khoom muaj peev xwm. Xav tias dawb mus xyuas nrog tus neeg muag khoom rau txhua cov ntaub ntawv koj xav tau.
