Cov mis thiab txheej txheem ntawm gypsum mortar tshiab

Tsim ib lub gypsum mortar tshiab yuav tsum tau ua tib zoo xav txog cov khoom uas xav tau thiab kev ua tau zoo. Ntawm no yog ib qho kev qhia dav dav thiab txheej txheem rau kev tsim ib qho yooj yim gypsum mortar:

Cov khoom xyaw:

1. Gypsum: Gypsum yog thawj binder nyob rau hauv mortar thiab muab qhov tsim nyog adhesion thiab lub zog. Nws feem ntau tuaj nyob rau hauv daim ntawv ntawm gypsum plaster los yog gypsum hmoov.
2. Aggregates: aggregates xws li cov xuab zeb lossis perlite tuaj yeem ntxiv txhim kho cov haujlwm ua haujlwm, thiab cov yam ntxwv ntawm lub tshuaj khib.
3. Dej: Dej yog qhov tseem ceeb rau hydrating lub gypsum thiab tsim ib qho chaw ua haujlwm.

Additives (Yeem):

1. Retarders: Retarders tuaj yeem raug ntxiv los tswj lub sijhawm teeb tsa ntawm lub mortar, tso cai rau lub sijhawm ua haujlwm ntev dua.
2. Modifiers: Ntau yam kev hloov pauv xws li cellulose ethers, polymers, lossis cov neeg ua haujlwm huab cua tuaj yeem koom ua ke los txhim kho cov khoom tshwj xeeb xws li kev ua haujlwm, dej tuav, lossis kav ntev.
3. Accelerators: Accelerators tuaj yeem suav nrog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam cov kab
4. Fillers: Fillers xws li lub teeb yuag aggregates lossis microspheres tuaj yeem siv los txo qhov ceev thiab txhim kho thermal lossis acoustic rwb thaiv tsev.

Txheej txheem:

1. Kev sib xyaw:
   • Pib los ntawm kev ntsuas ua ntej qhov xav tau ntawm gypsum, aggregates, thiab additives raws li qhov xav tau formulation.
   • Muab cov khoom xyaw qhuav (gypsum, aggregates, fillers) nyob rau hauv ib lub nkoj sib tov los yog tov khoom thiab sib tov kom huv si kom txog thaum homogeneous.
2. Ntxiv dej:
   • Maj mam ntxiv dej mus rau qhov sib tov qhuav thaum sib tov tsis tu ncua kom txog rau thaum cov khoom sib xyaw ua haujlwm tau tsim.
   • Cov dej-rau-gypsum piv yuav tsum tau ua tib zoo tswj kom ua tiav qhov xav tau sib xws thiab lub sijhawm teeb tsa.
3. Incorporating Additives:
   • Yog tias siv cov khoom siv ntxiv xws li retarders, accelerators, lossis modifiers, ntxiv rau qhov sib xyaw ua ke raws li cov chaw tsim khoom cov lus qhia.
   • Sib tov cov mortar kom huv si kom paub meej cov khoom sib faib ntawm cov khoom ntxiv thiab kev ua haujlwm zoo ib yam.
4. Kev kuaj thiab kho:
   • Ua kev ntsuam xyuas ntawm cov mortar tshiab tshiab los ntsuas cov khoom xws li kev ua haujlwm tau zoo, teeb tsa lub sijhawm, kev txhim kho lub zog, thiab kev ua kom zoo.
   • Kho cov qauv tsim raws li qhov xav tau raws li cov txiaj ntsig kev xeem thiab cov qauv kev ua haujlwm xav tau.
5. Daim ntawv thov:
   • Siv cov gypsum mortar rau lub substrate siv cov tswv yim tsim nyog xws li troweling, txau, los yog nchuav.
   • Xyuas kom muaj kev npaj nto thiab substrate compatibility kom pom adhesion thiab kev ua tau zoo.
6. Kho:
   • Cia lub mortar kho thiab teem caij raws li lub sijhawm teev tseg, suav nrog cov xwm txheej ib puag ncig xws li kub thiab av noo.
   • Saib xyuas cov txheej txheem kho thiab tiv thaiv cov mortar los ntawm kev ziab ntxov ntxov lossis raug rau cov xwm txheej tsis zoo.
7. Kev Tswj Xyuas Zoo:
   • Ua cov kev ntsuam xyuas zoo ntawm cov tshuaj khib nyiab los ntsuam xyuas cov khoom xws li lub zog, durability, thiab dimension stability.
   • Ua ib qho kev hloov kho tsim nyog rau kev tsim qauv lossis kev siv cov txheej txheem raws li kev tswj xyuas tau zoo.

Los ntawm kev ua raws li cov qauv no thiab cov txheej txheem, koj tuaj yeem tsim ib lub gypsum mortar tshiab raws li cov kev xav tau tshwj xeeb, ua kom pom kev ua haujlwm zoo thiab ua haujlwm ntev. Nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo soj ntsuam thiab tswj kom zoo thoob plaws hauv txoj kev txhim kho kom ua tiav cov txiaj ntsig zoo ib yam thiab ua tau raws li cov qauv kev lag luam.
