1. Qhov sib xyaw ntawm mortar tsis raug
Cov mortar mix ratio muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm thermal rwb thaiv tsev mortar. Yog tias qhov piv ntawm cov khoom siv raw xws li cement, xuab zeb, thiabRDPtsis tsim nyog, lub zog thiab adhesion ntawm mortar yuav tsis txaus, yog li ua rau muaj kev pheej hmoo ntawm kev tawg. Piv txwv li, yog tias cov cement ntau dhau, qhov shrinkage ntawm cov mortar yuav nce, los yog RDP siv tsis raug, ua rau tsis txaus toughness ntawm mortar thiab yooj yim tawg.

2. Cement zoo teeb meem
Cement yog ib qho tseem ceeb ntawm cov khoom sib txuas hauv thermal rwb thaiv tsev mortar. Yog tias qhov zoo ntawm cov cement tsis ua raws li qhov yuav tsum tau ua, xws li qib tsis txaus, kev ua haujlwm tsis zoo lossis cov impurities ntau dhau, nws yuav ua rautsis zoo mortar adhesion thiab yooj yim tawg. Cov txheej txheem hydration ntawm cov cement txiav txim siab lub zog thiab ruaj khov ntawm cov mortar, thiab cov cement tsis zoo yuav ua rau cov tsos ntawm cov kab nrib pleb.
3. Kev cuam tshuam ntawm qhov kub thiab txias
Sab nrauv ib puag ncig muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm thermal rwb thaiv tsev mortar. Thaum lub sij hawm kev tsim kho,kub dhau los yog qis dhau, siab dhau lossis qis dhauyuav cuam tshuam cov txheej txheem hardening ntawm mortar, yog li ua rau qhov tshwm sim ntawm cov kab nrib pleb. Nyob rau hauv huab cua kub, dej evaporates sai heev, ua rau lub mortar nto shrinkage thiab tsim cov kab nrib pleb; thaum nyob rau hauv qhov kub tsis tshua muaj, cov cement hydration cov tshuaj tiv thaiv ntawm cov mortar qeeb, uas tseem yuav cuam tshuam rau lub zog ntawm cov mortar thiab ua rau muaj kev tawg.
4. Cov khib nyiab shrinkage
Lub thermal rwb thaiv tsev mortar yuav ntsws mus rau ib qho twg thaum lub sij hawm hardening txheej txheem. Yog tiasshrinkage ntawm mortar yog loj heev thiab nws tsis tau khaws cia nyob rau hauv lub sij hawm, cov kab nrib pleb yuav tshwm sim ntawm qhov chaw. Tshwj xeeb tshaj yog nyob rau hauv tuab mortar los yog loj-chav tsev tsim, lub shrinkage deformation yog loj, uas yog ib qho yooj yim ua rau tawg. Qhov ua rau shrinkage tuaj yeem cuam tshuam nrog rau yam xws li cov tshuaj khib nyiab tsis zoo, cov av qis hauv qhov chaw tsim kho, thiab kev saib xyuas tsis txaus.
5. Tsis sib xws los yog tsis raug kho lub hauv paus nto
Lub hauv paus tsis sib xws los yog impurities txuas rau saum npoo cuam tshuam qhov adhesion ntawm thermal rwb thaiv tsev mortar thiab lub hauv paus nto, uas yooj yim ua rau tawg. Yog lub hauv paus ntotsis kho kom zoo ua ntej kev tsim kho(xws li ntxuav, leveling, thiab lwm yam), adhesion ntawm lub mortar thiab lub hauv paus nto yog tsis zoo, thiab cov kab nrib pleb yuav tshwm sim thaum lub sij hawm ziab.

6. Kev siv tshuab tsis raug
Kev tsim kho tshuab yog ib qho tseem ceeb ntawm cov thermal rwb thaiv tsev mortar zoo. Txoj kev tsim kho tsis raug xws lidaim ntawv thov tsis sib xws, thicknesses sib txawv, ceev heev los yog qeeb siv ceevyuav ua rau uneven shrinkage ntawm mortar txheej thiab tsim cov kab nrib pleb. Tsis tas li ntawd, kev sib xyaw tsis sib xws lossis kev sib xyaw ntau dhau ntawm cov tshuaj khib kuj tseem cuam tshuam rau kev ua haujlwm ntawm cov mortar thiab ua rau tawg.
7. Sab nraud quab yuam
Tom qab kev tsim kho ntawm thermal rwb thaiv tsev mortar, sab nraud quab yuam (xws liKev hloov pauv kub, av noo hloov, kev sib hais hauv tsev, thiab lwm yam.) kuj tuaj yeem ua rau tawg. Tshwj xeeb tshaj yog thaum lub sij hawm kev sib hais haum ntawm lub tsev, lub mortar txheej yog stretched los yog compressed, uas yog nquag mus rau tawg.
8. Kev demoulding ntxov ntxov lossis kev kho tsis raug
Tom qab kev tsim kho tiav, lub thermal rwb thaiv tsev mortar yuav tsum tau tswj kom txaus ua ntej demoulding kom ntseeg tau tias lub mortar tuaj yeem ua kom muaj dej txaus thiab tawv. YogTsis muaj av noo txaus lossis lub sijhawm khoThaum lub sij hawm hardening txheej txheem, lub mortar yuav ua rau saum npoo kom qhuav thiab tawg vim yog dej ntau dhau. Tsis tas li ntawd, kev demoulding ntxov ntxov los yog tsis tsim nyog rau sab nraud kuj tseem tuaj yeem ua rau muaj cov kab nrib pleb ntawm cov tshuaj khib nyiab.
9. Cov teeb meem zoo ntawm cov khoom siv rwb thaiv tsev nws tus kheej
Yog tias cov ntaub ntawv rwb thaiv tsev (xws lipolystyrene boards, extruded boards, thiab lwm yam.) siv nyob rau hauv lub rwb thaiv tsev mortar yog tsis tsim nyog los yog tsis zoo, cov qauv ntawm cov mortar txheej yuav tsis ruaj khov thiab tawg yuav tshwm sim. Piv txwv li, qhov tsis zoo adhesion ntawm lub rwb thaiv tsev board thiab mortar, los yog muaj npuas thiab tawg nyob rau hauv cov ntaub ntawv rwb thaiv tsev, yuav cuam tshuam rau tag nrho cov stability ntawm lub mortar.
10. Tshuaj tiv thaiv
Qee qhov xwm txheej, cov khoom siv ntxiv siv rau hauv cov khoom siv rwb thaiv tsev ua rau muaj kev cuam tshuam tsis zoo nrog lwm cov ntaub ntawv, ua rau muaj kev hloov pauv ntawm lub cev ntawm lub mortar, uas tuaj yeem ua rau tawg. Piv txwv li, qee yam tshuaj lom neeg ua haujlwm nrog cov cement los tsim cov khoom lag luam nthuav dav lossis kev cog lus, uas cuam tshuam rau qhov hardness thiab stability ntawm cov mortar thiab ua rau tawg.
Lub cim ntawm cov kab nrib pleb nyob rau hauv lub rwb thaiv tsev mortar yog qhov tshwm sim ntawm kev sib koom ua ke ntawm ntau yam, suav nrograw khoom piv, txheej txheem tsim, ib puag ncig tej yam kev mob, puag nto kho, thiab lwm yam. txhawm rau tiv thaiv kev tsim cov kab nrib pleb, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj txhua qhov txuas thaum lub sij hawm tsim kho, xaiv cov khoom tsim nyog, xyuas kom tsim nyog siv thev naus laus zis, thiab tsim nyog tswj kev tsim kho ib puag ncig thiab kev saib xyuas. Los ntawm cov kev ntsuas no, qhov tshwm sim ntawm cov kab nrib pleb tuaj yeem txo qis thiab qhov ua tau zoo thiab kev pabcuam lub neej ntawm thermal rwb thaiv tsev mortar tuaj yeem txhim kho.
