NOBETH CH 48KW Tag Nrho Tsis Siv Neeg Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob yog siv rau kev kho pob zeb

Lub luag haujlwm ntawm cov khoom siv ua kom sov ua kom sov

Thaum lub caij ntuj no kev tsim kho, qhov kub thiab txias yog qis thiab huab cua qhuav. Lub pob zeb hardens maj mam thiab lub zog yog qhov nyuaj kom ua tau raws li qhov xav tau. Lub hardness ntawm cov khoom ua vaj tse uas tsis muaj chav kho yuav tsum tsis ua raws li tus qauv. Kev siv chav kho kom zoo dua qub tuaj yeem ua tiav los ntawm ob lub ntsiab lus hauv qab no:

1. Tiv thaiv cov kab nrib pleb. Thaum qhov kub ntawm sab nraud poob mus rau qhov chaw khov, cov dej hauv cov pob zeb yuav khov. Tom qab cov dej hloov mus rau hauv dej khov, qhov ntim yuav nthuav dav sai sai hauv lub sijhawm luv luv, uas yuav ua kom puas cov qauv ntawm cov pob zeb. Nyob rau tib lub sijhawm, huab cua qhuav. Tom qab cov pob zeb hardens, nws yuav tawg yuav tsim thiab lawv lub zog yuav tsis muaj zog lawm.

2. Cov khoom siv ua kom sov muaj dej txaus rau hydration. Yog tias cov dej noo ntawm qhov chaw thiab sab hauv ntawm cov pob zeb dries sai heev, nws yuav nyuaj rau kev hydration txuas ntxiv. Kev kho chav dej tuaj yeem tsis tsuas yog ua kom muaj qhov kub thiab txias uas yuav tsum tau ua kom cov pob zeb ua kom tawv, tab sis kuj ua kom cov av noo, ua kom cov evaporation ntawm cov dej, thiab txhawb cov hydration cov tshuaj tiv thaiv ntawm cov pob zeb.

Yuav ua li cas ua steam curing nrog chav?

Hauv kev kho pob zeb, ntxiv dag zog rau kev tswj cov av noo thiab qhov kub thiab txias ntawm cov pob zeb, txo lub sij hawm cuam tshuam ntawm cov pob zeb, thiab npog qhov chaw ntawm cov pob zeb kom nruj kom raws sijhawm. Nws tuaj yeem npog nrog daim ntaub, ntawv yas, thiab lwm yam los tiv thaiv evaporation. Ua ntej pib kho cov pob zeb uas nthuav tawm cov txheej txheem tiv thaiv, lub npog yuav tsum tau dov thiab cov npoo yuav tsum tau rubbed thiab compressed nrog plaster yam tsawg kawg ob zaug kom nws du thiab npog dua.

Nyob rau lub sijhawm no, kev saib xyuas yuav tsum tau saib xyuas tias qhov sib tshooj yuav tsum tsis txhob cuam tshuam ncaj qha nrog cov pob zeb ua kom txog thaum cov pob zeb tau kho thaum kawg. Tom qab nchuav cov pob zeb, yog tias huab cua kub, huab cua qhuav, thiab cov pob zeb tsis kho tau raws sijhawm, cov dej hauv cov pob zeb yuav evaporate sai heev, ua rau lub cev qhuav dej, yog li cov cement uas tsim cov gel tsis tuaj yeem ua kom tiav cov khoom siv. dej thiab kho tsis tau.

Tsis tas li ntawd, thaum lub pob zeb muaj zog tsis txaus, evaporation ntxov ntxov yuav ua rau loj dua shrinkage deformation thiab shrinkage tawg. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau siv lub pob zeb kho lub tshuab hluav taws xob los kho cov pob zeb thaum ntxov ntawm kev nchuav. Lub pob zeb yuav tsum tau kho tam sim ntawd tom qab qhov kawg cov duab tau tsim thiab qhuav tawv pob zeb yuav tsum tau kho tam sim ntawd tom qab pouring.
