01 Qhia Txog Tus Vaj Ntxwv ntawm mortar
Mortar king yog ib lub npe nrov, qee cov neeg kuj hu ua pob zeb essence, cement plasticizing agent. Nws yog ib hom kev ua yeeb yam ntawm cov ntawv khi (cement), txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv cement mortar, belongs rau qeb ntawm cov khoom sib xyaw ua ke. Lub luag haujlwm tseem ceeb yog txhawm rau txhim kho kev ua haujlwm thiab dej khaws cia ntawm mortar, txhim kho kev ua haujlwm ntawm kev tso cib thiab mortar, txo cov av tshauv, thiab txuag cov cement thiab pob zeb plaster. Nyob rau hauv mortar mas plays lub luag hauj lwm ntawm diffusion cement, emulsification thiab foaming. Muaj peev xwm kov yeej lub plhaub, tawg thiab lwm yam teeb meem, nyob rau hauv aerated qhob, zoo tib yam qhob qhob av, hauv qab los yog nto txheej yog qhov zoo tshaj plaws siv, masonry mortar puv degree siab, hardened nrog Frost tsis kam, dej txo, seepage, durability, tawg kuj. , kev txuag hluav taws xob, rwb thaiv tsev kub thiab lwm yam haujlwm.
02 Cov khoom ua tau zoo
1, nrog kev ua haujlwm zoo, txhim kho lub zog ntawm mortar, tsis yog cov txiv qaub, txuag cov cement.
2. Nws muaj kev tiv thaiv zoo khov, impermeability thiab noo noo tsis kam.
3, txhim kho cov mortar adhesion, kov yeej lub plhaub, tawg, xuab zeb thiab lwm yam tsis zoo.
4. Nws muaj elasticity zoo, kev ua haujlwm tau zoo dua qub, thiab kev siv zog txo qis.
03 Khoom nta
Nws yog tsim rau txhua yam kev lag luam thiab pej xeem vaj tse nyob rau hauv av nplaum cib, ceramic cib, hollow cib, ntub cement thaiv, unfired cib masonry, sab hauv thiab sab nrauv phab ntsa plastering, ceramic pobzeb, pem teb, ru tsev, txoj kev thaiv, culvert, hauv qab daus, pas dej ua ke , kev tsim kho chav dej.
04 Cov yam ntxwv ntawm
1, txhim kho kev ua haujlwm ntawm mortar dej tuav; mortar swelling, mos, zoo fluidity, muaj zog adhesion, txo cov av tshauv thiab txo cov nqi, plastering, tsis tshua muaj yuav tsum tau rau phab ntsa ntub dej, mortar shrinkage, mortar dej tuav, tsawg los ntshav npaum li cas khaws cia 6-8 teev tsis muaj nag lossis daus, tsis tas yuav rov ua dua. , ceev kev tsim kho, txhim kho kev ua haujlwm ntawm kev ua haujlwm.
2, thaum ntxov muaj zog muaj nuj nqi: sib tov mortar mortar siv lead ua npaj, nws muaj thiab cement affinity thiab ntxiv dag zog rau cov nyhuv, los ntawm kev ua kom cov cement kev ua si, nyob rau hauv 5-6 teev tom qab siv mus cuag ib tug tej yam lub zog, tom qab lub zog yog zoo dua.
3, waterproof thiab impermeable: mortar siv lead ua muaj cov tshuaj hydrophobic, tuaj yeem ua tiav cov nyhuv dej tsis zoo tom qab siv.
4, nce lub luag hauj lwm ntawm lub cev: nyob rau hauv cov cement xuab zeb nrog tib yam, infiltration mortar mortar siv lead ua los ntawm cov txheej txheem sib tov nyob rau hauv mortar tuaj yeem qhib rau hauv suav tsis txheeb micropores, nce lub cev 15%, lub zog tsis txo.
5, ntsuab kev tiv thaiv ib puag ncig: mortar siv lead ua yuav tsis tsim cov tebchaw tshiab, tsis muaj tshuaj lom, tsis-combustible, nyob rau hauv steel bar tsis xeb, nws durability yog ho zoo dua li qub mortar, mortar lig zog yog siab.
