Castable kev tsim kho tsom mus rau ntau qhov sib txuas xws li tus pin vuam, bitumen painting, dej sib tov, pwm kho, vibrating, pwm tso tawm tiv thaiv, kev ruaj ntseg loj, thiab qhov tseeb ntawm kev ntsuas cov ntsiab lus, thiab kev ua raws li cov kev cai ntawm cov khoom. chaw tsim tshuaj paus thiab boiler Hoobkas.
1. Pin thiab tuav ntsia ntsia ntsia
Ua ntej cov dej siab, cov pins nyob rau hauv cov cheeb tsam xws li vuam cov pob qij txha ntawm cov cua sov saum npoo thiab cov vuam sib txuas ua ke thiab cov pob qij txha ntawm cov cua sov saum npoo thaum lub sij hawm kev thauj mus los thiab kev teeb tsa yuav tsum tau ntim. Kho cov vuam thiab tuav cov ntsia hlau kom paub meej tias cov pins tau teeb tsa raws li qhov tsim ntom ntom. Ua ntej nchuav, siv ib txheej ntawm cov xim asphalt nrog lub thickness ntawm> 1mm ntawm tag nrho cov khoom siv hlau, rau tes thiab lwm yam hlau los yog qhwv cov khoom siv hluav taws xob.
2. Cov khoom xyaw, dej faib, sib tov tswj
Cov khoom xyaw yog hnyav thiab cov dej tau muab faib ua nruj raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv ntawm cov khoom siv ntawm cov chaw tsim khoom, thiab tus neeg tsim khoom yog lub luag haujlwm rau kev ntsuas qhov tseeb. Cov dej uas siv rau kev sib xyaw castables yuav tsum yog dej huv (xws li dej haus), nrog rau pH ntawm 6 ~ 8. Ua tib zoo saib xyuas qhov kev txiav txim ntawm kev ntxiv dej thiab lub sijhawm sib xyaw thiab sib xyaw. Nws tsis raug tso cai ntxiv dej ntawm qhov xav tau, thiab nws tsis raug tso cai ua ntej lossis ncua sijhawm sib xyaw ua ke. Tus nqi ntawm cov dej yuav tsum tsis txhob muab ntxiv rau hauv ib qho chaw, thiab cov castable yuav tsum tau tov tag nrho. Nws yog ib qho tsim nyog yuav tsum tau ntxiv cov hlau fiber ntau rau lub castable thaum lub sij hawm tus txheej txheem ntawm kev ntxiv dej thiab sib tov, thiab yuav tsum tsis txhob tov nyob rau hauv agglomerates.
3. Cov qauv tswj
Castable pwm ua yog txheej txheem tseem ceeb heev, thiab qhov zoo ntawm cov pwm phaj ncaj qha cuam tshuam rau qhov zoo ntawm castable. Lub template tswj tsom rau qhov kev lees paub ntawm nws qhov ruaj khov thiab qhov tseeb qhov tseeb. Lub template yuav tsum ruaj thiab nruj sib sau ua ke kom ntseeg tau tias tsis muaj kev txav los yog xoob thaum lub sij hawm nchuav. Cov ntoo pwm yuav tsum tau nteg tawm raws li geometric qhov ntev ntawm kev tsim cov duab kos thiab cov thickness, prefabricated thiab sib sau ua ke, thiab lub interface yog nruj. Cov pwm yog tsim los ntawm 15 cm template thiab ntoo square, nrog ib tug dav ntawm ≤500mm; cov pwm tshwj xeeb yog ua los ntawm cov ntoo square thiab npog nrog ib txheej txheej txheej peb-centimeter board, qhov saum npoo yog txhuam nrog ob tus neeg tso tawm los xyuas kom meej lub thickness ntawm cov castable thiab nto tom qab kev tsim kho yog du thiab huv si tsis muaj pitting. Lub formwork yuav tsum tau kuaj xyuas thiab lees txais ua ntej kev tsim kho.
4.Pouring tswj
Thaum pouring lub castable, qhov siab ntawm txhua qhov pub yog tswj nyob rau hauv qhov ntau ntawm 200 ~ 300mm, ib feem nrog thickness ntau tshaj 50 hli yog poured nrog ib tug ntxig vibrator vibrating, thiab "ceev nyob rau hauv thiab qeeb tawm" txoj kev yog siv rau vibrate tsis tu ncua Thaum lub sij hawm vibrating los tiv thaiv kev tuav Rau qhov qis qis thiab qhov xau vibration, lub sij hawm vibration ntawm txhua qhov taw tes yuav tsum tsis txhob ntev dhau los tiv thaiv cov hmoov zoo los ntawm ntab. Thaum lub sij hawm vibration txheej txheem, lub vibrating pas nrig yuav tsum tsis txhob ntaus lub template thiab nuv rau tes ntau dhau. Thaum pouring castables ntau dua 50 hli tuab, thaj tsam ntau dua 10m2 yuav tsum tau tsim ntawm ob lub ntsiab lus tib lub sijhawm; txhawm rau xyuas kom meej tias cov khoom sib xyaw yog nchuav rau hauv lub sijhawm teev tseg, lub ncuav ntawm qhov tsawg tshaj li 50mm tuab yog nyiam ua tus kheej-leveling thiab tsis siv neeg Degassed nws tus kheej ntws castable tsim.
5.Reservation ntawm expansion pob qij txha
Vim hais tias qhov expansion coefficient ntawm cov castable yog inconsistent nrog expansion coefficient ntawm cov hlau, nws yog hais txog ib nrab ntawm cov hlau. Feem ntau, muaj plaub txoj hauv kev los daws qhov nthuav dav ntawm cov castable: ib qho yog pleev xim rau cov xim asphalt ntawm tus pin thiab hlau nto, lub thickness tsis tsawg tshaj li 1 hli. Qhov thib ob yog qhov loj-thaj chaw pouring ib feem, uas yog poured nyob rau hauv blocks txhua txhua 800 ~ 1000 × 400, thiab cov expansion sib koom cov khoom yog pasted los ntawm sab kom tawm lub expansion sib koom ua ke. Qhov thib peb yog cua kub ceramic fiber ntawv nrog lub thickness ntawm 2 hli nyob rau saum npoo ntawm lub hood, ntsuas yeeb nkab fittings, thiab hlau phab ntsa nkag mus rau hauv lub expansion pob qij txha. Plaub, rab riam tuaj yeem siv los txiav tawm ib nrab-thickness qhov sib txawv thaum lub sij hawm tsim kho cov yas, los yog ib lub qhov tuaj yeem raug punched hauv cov yas los daws qhov teeb meem ntawm kev nthuav dav.
