QualiCell cellulose ether HPMC / MHEC cov khoom tuaj yeem ua rau cov cement hydrated, ua kom lub zog sib txuas, thiab tuaj yeem ua rau muaj zog tensile bonding zog thiab shear bonding zog ntawm cov mortar hardened mortar. Lub caij no, nws tuaj yeem txhim kho kev ua haujlwm tau zoo thiab lubricity, zoo heev txhim kho kev tsim kho thiab txhim kho kev ua haujlwm.
Cellulose ether rau Masonry Mortar
Masonry mortar yog hais txog mortar uas cib, pob zeb, thiab cov khoom thaiv tau ua rau hauv masonry. Nws plays lub luag hauj lwm ntawm cov txheej txheem thaiv, pob zeb thiab quab yuam, thiab yog ib feem tseem ceeb ntawm masonry cement slurry. Cement bricks yog siv los tsim cov masonry nrog cov kev xav tau siab rau cov cement ib puag ncig thiab lub zog. Cib lintels feem ntau siv cov cement mortar nrog lub zog ntawm qib 5 txog M10; bricks feem ntau siv cov cement mortar uas tsis yog M5; cov tsev qis lossis bungalows tuaj yeem siv cov txiv qaub mortar; Cov khoom siv hauv tsev yooj yim, txiv qaub av nplaum mortar, tuaj yeem siv tau.
Cement yog cov khoom siv cementing tseem ceeb ntawm mortar. Cov cement feem ntau siv xws li cov cement, slag cement, pozzolan cement, ya tshauv cement thiab composite cement, thiab lwm yam, uas tuaj yeem xaiv tau raws li cov qauv tsim, masonry cib thiab cement ib puag ncig. Cov cement muaj zog tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Lub zog qib ntawm cov cement siv hauv cov cement xuab zeb yuav tsum tsis txhob siab dua 32.5; Lub zog qib ntawm cov cement siv hauv cov cement sib xyaw mortar yuav tsum tsis txhob siab dua 42.5. Yog tias qib cement lub zog siab dhau lawm, koj tuaj yeem ntxiv qee cov khoom sib xyaw. Rau qee lub hom phiaj tshwj xeeb, xws li teeb tsa cov pob qij txha thiab cov pob qij txha ntawm cov khoom siv, lossis rau kev txhim kho thiab kho cov kab nrib pleb, cov cement expansive yuav tsum tau siv. Cov khoom siv cementitious siv nyob rau hauv masonry mortar muaj xws li cov cement thiab txiv qaub. Kev xaiv ntawm cov cement ntau yam yog tib yam li cov pob zeb. Cov qib cement yuav tsum yog 45 npaug ntawm qib zog ntawm mortar. Yog tias qib cement siab dhau lawm, cov cement yuav tsis txaus, ua rau cov dej tsis zoo. Txiv qaub muab tshuaj txhuam thiab slaked txiv qaub tsis tsuas yog siv los ua cov khoom siv cementing, tab sis tseem ceeb tshaj, ua kom cov mortar muaj dej tuav tau zoo. Fine aggregate Fine aggregate feem ntau yog cov xuab zeb ntuj, thiab cov mortar uas npaj tau hu ua mortar zoo tib yam. Cov ntsiab lus av nplaum hauv cov xuab zeb yuav tsum tsis pub tshaj 5%; Thaum lub zog qib qis dua m2.5, cov ntsiab lus av nplaum yuav tsum tsis pub tshaj 10%. Qhov siab tshaj particle loj ntawm cov xuab zeb yuav tsum tsawg dua 1/41/5 ntawm lub thickness ntawm mortar, feem ntau tsis ntau tshaj 2.5 hli. Raws li mortar rau grooves thiab plastering, qhov siab tshaj particle loj tsis tshaj 1.25 mm. Lub thickness ntawm cov xuab zeb muaj kev cuam tshuam zoo ntawm cov cement, workability, lub zog thiab shrinkage.
