Dab tsi ntawm Refractory Castable yog siv rau hauv ob sab phlu loj loj Windbox?

Yuav ua li cas hom ntawm refractory castable yog siv rau hauv ob sab phlu loj cua tshuab?

Lub chimney hauv ob sab phlu belongs rau lub acidic cua, uas yog tshwm sim los ntawm acid gas yaig thiab yaig. Lub hauv ob sab phlu feem ntau yog ua los ntawm cov kua qaub-resistant refractory castables, thiab kev tsim kho thickness yog li 100 hli.

1. Qhov siab sib txawv xav tau kev tsim kho sib txawv

Vim tias cov chimneys muaj qhov siab sib txawv, txoj kev tsim kho kuj txawv. Ib txhia yog tsim rau hauv av thiab ces hoisted thiab ntsia nruab nrab. Ib txhia ntawm lawv yog tsim los ntawm qhov chaw siab. Yog tias lub chimney siab dhau lawm, kev tsim kho yuav nyuaj heev. Txawm li cas los xij, cov kab nrib pleb lossis cov kab nrib pleb yuav tshwm sim hauv cov kab hluav taws xob hauv lub qhov koob tom qab kev tsim kho, thiab cov kab nrib pleb thiab cov kab nrib pleb yuav maj mam nthuav dav, qee zaum txawm txuas mus rau tag nrho cov kab hluav taws xob. Qee zaum, muaj tev lossis bulging.

2. Muaj plaub yam

Muaj plaub qhov laj thawj: ua ntej, nws yog tshwm sim los ntawm qhov kub thiab txias kev ntxhov siab hauv lub chimney; thib ob, nws yog tshwm sim los ntawm shrinkage kev nyuaj siab; thib peb, nws yog tshwm sim los ntawm inconsistent shrinkage ntawm kev sib koom nto ntawm acid-resistantrefractory castablecov ntaub ntawv. Plaub, lub binder tsis nco qab muab ntxiv thaum nplawm cov kua qaub-resistant castable. Thaum plaub qhov xwm txheej no tshwm sim, kho lawv raws sijhawm. Rau cov cheeb tsam bulging, do cov kua qaub-resistant castable thiab chisel lawv tawm ncaj qha ua ntej pouring rau lawv. Thaum sau, lawv yuav tsum tau muab khawb rau hauv ib qho dovetail style, uas yog, me me rau saum thiab loj hauv qab. Qhov no muaj txiaj ntsig. txuas.
Yog tias cov kab nrib pleb pom tom qab tshem tawm cov formwork, nws yog vim tias cov formwork raug tshem tawm ntxov dhau. Yog tias pom thaum tshem tawm, nws tuaj yeem kho tam sim ntawd.
Rau cov kab nrib pleb uas tshwm sim, koj yuav tsum tau tos kom qhov tawg kom ruaj khov, txog 45 hnub, ntxuav cov khib nyiab nyob ib ncig ntawm qhov tawg, thiab siv lub laum hlau txhawm rau tshem tawm qhov tawg. Ob feem peb ntawm cov tuab ntawm cov kua qaub-resistant refractory castable yog sib npaug rau qhov dav ntawm qhov tawg ntawm ob sab. Txhua lub tsev pheeb suab yog 50 hli tuab thiab yuav tsum tau ntim nrog acid-resistant castables uas tseem tshuav thaum tsim kho.
Kev kho tsuas yog ib txoj hauv kev kho, tab sis kev tiv thaiv kev tsim kho yog qhov tseem ceeb. Thaum lub sij hawm tsim kho ntawm acid-resistant ntiav ntiav cov ntaub ntawv, additives yuav tsum tau ntxiv. 3 teev tom qab nchuav thiab demoulding, siv 2.5 ~ 3. Qhov sib txuas txuas yog 1500mm × 1500mm thiab seam qhov tob yog 2.5mm. Qhov no tiv thaiv qhov tshwm sim ntawm cov kab nrib pleb.

3. Ua kom tsis pub tsawg tshaj 10 teev thiab tsis txhob do thinly.

Tsis tas li ntawd, lub sij hawm demoulding ntawm acid-resistant refractory castables tsis tuaj yeem tsawg dua 10 teev, thiab lub sijhawm demoulding lossis lub zog ntawm cov castables thaum demoulding yog tswj nruj heev. Tsis txhob demoulding ntxov ntxov thiab tawg. Yog tias nws yog qhov tsaus ntuj corbel txoj hauj lwm, cov kua qaub-resistant castable yuav tsum tsis txhob sib tov heev thinly, thiab qhov kev faib ua feem ntawm binder yuav tsum tau nruj me ntsis raws li kom ntseeg tau tias tsis muaj kab nrib pleb tshwm sim thaum lub sij hawm tsim kho ntawm tsaus corbel siab nyob rau hauv lub chimney.
