Tau thaiv tsev niaj hnub no, pob zeb ntaub plaub feem ntau siv. Nws yog qhov zoo vim tias nws tsis ntshai hluav taws, nws yooj yim rau nruab, thiab nws yog pheej yig. Ib qho ntawm nws nrov hom yog bas alt rwb thaiv tsev. Nws cov khoom thiab cov lus qhia tshwj xeeb nyob ntawm nws lub hom phiaj tshwj xeeb.

Cov khoom siv no yog ib qho huv tshaj plaws ntawm ecology. Qhov no rwb thaiv tsev ua raws li ib yam ntawm cov ntxhia wool, yog li nws muaj ob peb lub npe, ntawm lawv - pob zeb los yog bas alt ntaub plaub. Nws surpasses tag nrho lwm yam ntawm cov ntxhia wool nyob rau hauv cov nqe lus ntawm lub zog yam ntxwv thiab muaj kev nyab xeeb kiag li rau xwm thiab tib neeg. Tsis ntev los no, bas alt cylinders tau dhau los ua ntau dua, thiab lawv yuav tau tham hauv kab lus.

Kev piav qhia

Cov thooj voos kheej kheej no tseem hu ua lub plhaub thiab yog lub rhaub nrog cov kab sib txawv thiab tuab. Nws yog tsim los ntawm high-density bas alt fiber, uas yog 75 kg / m 3. Cov khoom yuav coated, thiabkuj muaj qhov zoo tsis txaus ntseeg tshaj lwm lub tshuab cua sov. Cov cylinders raug txiav kom yooj yim ntawm kev teeb tsa thiab tso cai rau rov siv cov khoom siv no yam tsis muaj kev cuam tshuam kev ua haujlwm.

Bas alt thooj voos kheej kheej tuaj yeem coated nrog fiberglass, aluminium ntawv ci, fiberglass thiab lwm yam ntaub ntawv txheej uas tsim los ua kom hnav tsis kam. Ntawm kev muag khoom koj tuaj yeem nrhiav Bas alt-Pipe, uas yog npaj ua thermal rwb thaiv tsev ua los ntawm bas alt fiber. Cov khoom siv rau cov kav dej yog npaj thiab tsim nyob rau hauv daim ntawv ntawm ntu thiab lub tog raj kheej.

Txoj Kev Ua Haujlwm

Bas alt lub tog raj kheej yog tsim raws li GOST 23208-83. Nyob rau hauv cov txheej txheem, niaj hnub European cov cuab yeej thiab cov ntaub ntawv siv tau raws li kev ruaj ntseg hluav taws thiab ib puag ncig yuav tsum tau. Cov kav dej zoo li no yog cov qauv tsim los ntawm cov txheej txheem nruj tsim bas alt thiab npog txheej.

Lub tog raj kheej tuaj yeem ntev 1m thiab tsim los rau cov yeeb nkab sib txawv. Nyob rau hauv cov ntaub ntawv no, lub thickness ntawm insulating txheej yuav ua tau tej yam. Ntawm cov thev naus laus zis ntau lawm, nws tsim nyog qhia txog cov txheej txheem ntawm nchuav cov fibers nyias nrog cov khoom siv hluavtaws.

Cov khoom siv tuaj yeem siv rau thermal rwb thaiv tsev ntawm cov kav dej, qhov chaw sab nrauv tuaj yeem ua kom sov txog + 250 ˚С. Kev tsim cov thev naus laus zis tuaj yeem sib txawv nyob ntawm seb cov khoom yuav tsum yog cov khoom tsim tawm. Thawj txheej txheem suav nrog kev siv hydromass, qhov thib ob -boards ntawm semi-qhuav thiab kub nias, thaum lub 3rd ib qho ntxiv ntawm ib tug bituminous binder.

Cov lus qhia rau kev siv

Bas alt thooj voos kheej kheej yog siv rau thermal rwb thaiv tsev ntawm cov kav dej hauv tsev thiab hauv tsev. Txij li nws yog raws li cov khoom siv ib puag ncig, nws tuaj yeem siv tau rau txhua hom kev lag luam, suav nrog zaub mov. Qhov chaw uas lub rhaub yuav siv tau tuaj yeem muaj lub hom phiaj. Lub tog raj kheej tsim nyog rau kev ua haujlwm nyob rau hauv cov xwm txheej sib txawv, nws tuaj yeem nyob sab hauv tsev lossis sab nraum zoov.

Cov plhaub zoo li no yog siv rau saum av thiab hauv av. Xws li lub tog raj kheej yog txoj hauv kev zoo tshaj plaws los ua kom zoo tshaj qhov poob ntawm cov cua sov hauv cov cua sov thiab cov khoom siv hluav taws xob. Pob zeb wool cylinders yog yooj yim heev rau nruab. Txhawm rau ua qhov no, lawv tsuas yog yuav tsum tau qhib los ntawm txoj hlua ntev thiab muab tso rau hauv cov yeeb nkab. Cov khoom lag luam muaj tees thiab khoov, uas pab cais cov teeb meem feem ntau ntawm cov kav dej, uas yog:

• tie-ins;
• kev hloov pauv;
• knee.

Kub-insulating bas alt cylinders tso cai rau koj los tsim lub kaw lus tsis muaj cov pob qij txha thiab cov seams, uas yuav tsum tau kaw nrog txhuas daim kab xev thaum lub sij hawm installation. Txhawm rau tiv thaiv cov rwb thaiv tsev los ntawm lwm yam xws li kev puas tsuaj thiab nag lossis daus, lub tog raj kheej coated lossis lub tog raj kheej cua sov, uas yog tsim los ntawm cov galvanized casings, yuav tsum tau siv.

Cov lus pom zoo rau kev txhim kho ntxiv

Ib qho ntawm cov theem tseem ceeb ntawm txoj hauv kev kom cov rwb thaiv tsev zoo yog kev ua tiav ntawm kev teeb tsa ua haujlwm. Manipulations yuav tsum tau nqa tawm los ntawm flange kev twb kev txuas. Lub tog raj kheej yuav tsum tau muab ntsia ze rau ib leeg. Kab rov tav seams yuav tsum tau spaced.

Fastening ntawm lub raj xa dej yog nqa tawm nrog galvanized knitting hlau lossis ntaub qhwv. Ob daim ntaub qhwv yog ntsia rau ntawm ib qho khoom, qhov kev ncua deb ntawm qhov yuav tsum yog 500 hli. Cov ntaub qhwv tuaj yeem ua los ntawm cov ntaub qhwv los yog cov hlua txhuas. Lawv fastening yog nqa tawm los ntawm buckles ua los ntawm nyias-daim ntawv galvanized hlau. Lawv thickness yuav tsum yog 0.8 hli. Nws tuaj yeem siv cov nplhaib ua los ntawm cov hlau dub annealed lossis galvanized steel, thaum lub cheeb ntawm cov khoom tuaj yeem ncav cuag 2 hli. Stainless hlau xaim siv tau.

Specifications

Lub tog raj kheej ua los ntawm cov ntxhia pob zeb bas alt ntaub plaub muaj cov thermal conductivity ntawm 0.04 W / mK. Synthetic binder tuaj yeem pib yaj nkaus xwb ntawm qhov kub siab tshaj 1000 ˚С. Kev pabcuam lub neej ntawm cov khoom zoo li no tshaj 50 xyoo. Lawv tsis shrinkage thiab resistant rau tshuaj. Lawv muaj qhov nqus dej tsawg, thiab qhov ntsuas kub tuaj yeem ncav cuag + 650 ˚С. Qhov qis dua yog - 150 ˚С. Kev nqus dej noo tsis tshaj 5%. Bas alt yeeb nkab cylinders yog cov khoom tsis-combustible.

Nyob hauv kaw

Tom qab kev teeb tsa lub tog raj kheej ntawm lub raj xa dej, lub plhaub tiv thaiv yuav tsum tau nruab. Nws yogua los ntawm galvanized hlau. Ib qho kev daws teeb meem yog 0.5 mm aluzinc. Lub thawv ntim yog ntsia los ntawm cov thawv ntim khoom ntim. Kev ua haujlwm yuav tsum pib ntawm lub li qub.

Cov ntaub thaiv npog yuav tsum tau nruab nrog kev sib tshooj. Thiab rau qhov yooj yim ntawm kev txuas lub casing, koj tuaj yeem siv txoj hlua khi-down nrog ratchet locking mechanism. Sab nraud txoj kab uas hla ntawm cov kav dej insulated tuaj yeem ncav cuag 915 mm. Ntawm cov theem tseem ceeb hauv kev tsim cov txheej txheem engineering, kev xaiv cov khoom siv insulating xav tau yuav tsum tau qhia. Kev muaj peev xwm tswj tau qhov xav tau ntawm cov cua sov lossis txias ntawm cov cab kuj nyob ntawm qhov no, nrog rau kev ua raws li cov kev cai ntawm kev nyab xeeb ntawm hluav taws.
