Ib tug tov Qhob

Niaj hnub no, qhov kev thov rau vaj tse, seb coj mus muag los yog lwm qhov, ua ib hnub los ntawm hnub. Thiab thiaj li ua xav tau kev pab nyob rau hauv lub tsev ntaub ntawv, tus zoo ibyam uas muaj xws li, ntawm chav kawm, ua vaj tse dlaws, txawv additives nyob rau hauv vaj tse, qhuav hmoov sib tov, thiab, ntawm chav kawm, kev daws teeb meem.

Yog li, rau masonry pob zeb tshuaj yuav muab tau tsevneeg solidity clinker los yog pob zeb rau tso. Polymer-tsev cov ntsiab muaj nyob rau hauv lawv cov kev twb kev txuas ntawm no yog cov khoom xyaw: dej (nyiam dua lim), MAAs (plaster, maas los txiv qaub) thiab sau ua ib pawg (xuab zeb thiab feem ntau gravelite). Feem ntau nyob rau hauv xws mixtures (rau masonry) kev faib ua feem ntawm txiv qaub thiab xuab zeb ntawm 1: 3 los yog 1: 4. Qhov no sib tov yog raug xa mus rau raws li builders Cug thawj pab pawg neeg (RG I). Thaum no rau cov dej (e.g., volume 80 litres), ntxiv ib ob peb MAAs spades, nyob rau hauv cov ntaub ntawv uas tau ib tug thib ob sib tov mortar pawg - WG II. Yuav kom tsim cov cab kuj lug los yog bases siv xis mas xuab zeb sib tov, uas yog siv nyob rau hauv kev tsim kho chaw feem ntau lwm tus neeg, thiab kev faib ua feem ntawm ib tug ib feem ntawm tej cheebtsam, ib chav tsev ntawm cov xuab zeb: peb units cementitious caij los yog ib tug ntawm cov xuab zeb: MAAs rau qhov chaw.

Nws yog feem ntau kuj siv plaster. Nws ua los ntawm ib tug unit ntawm txiv qaub thiab peb qhov chaw xuab zeb - nws yog rau sab nraum zoov siv. Raws li ib feem ntawm lub sab hauv ua hauj lwm, cov correlation ntawm lub Cheebtsam ntawm ob peb txawv - ib chav tsev ntawm txiv qaub rau hauv lub tsib qhov chaw ntawm xuab zeb. Maas plaster sib tov yog tsis tsawg nrov tshaj MAAs thiab xuab zeb mus rau lub hauv paus, thiab muaj cov nram qab no muaj pes tsawg leeg: kev faib ua feem ntawm cov xuab zeb thiab xis mas - 1: 3. Tam sim no ib tug ntau yam ntawm additives siv nyob rau hauv lub cement slurry nyob rau hauv thiaj li yuav txhim kho tus neeg kho tshuab thiab lub zog. Nrog regards gypsum raws li ib tug ruaj caij, nws freezes crystallization txheej txheem nws tus kheej, tsis muaj additives.

Thaum niag cubage sib tov nce, vim hais tias kom tsis txhob no, ntxiv ib me ntsis xuab zeb - ib feem rau ob qhov chaw ntawm gypsum. Los ntawm cov piv ntawm tus nqi ntawm cov phau ntawv thiab muab tub lim fatty distinguished, thiab cov pa nyias mortar mixtures. Fatty - saj zawg zog sib tov, tiam sis ua loj shrinkage thaum lub sij hawm tua, thiab yog hais tias muaj ntaub ntawv nrog ib tug tuab txheej - them nrog tej kab nrib pleb. Ntshiv muaj ib tug kuj me me ntawm lub phau ntawv lub caij, thiab, conversely, muab heev me ntsis shrinkage, nws yog tshwj xeeb yog menyuam thaum hnab twb qhib lawm.

Yog hais tias koj xav muab koj lub tsev ib tug tshwj xeeb tsw, mam li tso tseg koj xaiv rau dawb lias masonry mortar. Nyob rau hauv kev, xaiv kom phim rau txojkev khoom masonry sib tov yuav ua rau nws ua tau kom inconspicuous nqaws. Cug - ib tug zoo grain sib tov, uas yog kom huv si vymeryat, thiab nws muaj ib tug inorganic khoom, ib tug me me npaum li cas ntawm cov dej thiab me me zauv feem ntawm muab tub lim. Nws yog siv rau dai sab hauv thiab sab nraud tej hauj lwm, tab sis kuj rau pw lub cib thiab pob zeb phab ntsa. Muaj ib tug xov tooj ntawm hom kev daws teeb meem: ib tug waterproofing - ib tug ua ke ntawm MAAs, nyob rau hauv uas lub ntxiv Ceresit, ferric chloride thiab sodium aluminate; Ceresit - ib tug sib tov ntawm dawb xim, uas yog tau raws li ib tug tshwm sim ntawm combining amyl acid, txiv qaub, thiab ammonia; masonry - sib tov ntawm MAAs thiab txiv qaub los yog xis mas thiab av nplaum; Plaster - nws muaj xws li pulverized xuab zeb rau txheej txig du phab ntsa; MAAs - sib tov ntawm MAAs, xuab zeb thiab cov dej. Nyob ntawm seb lub hom tshuaj tus piv ntawm cov constituent ntsiab tej zaum yuav txawv. Tam sim no manufacturers muag ready-made sib tov sib txawv ntawm cov xim uas kis tawm nyob rau hauv lub hnab ntawm 10, 15, 25 thiab 1000 kg. Multicolored masonry kev daws teeb meem muaj ib tug xov tooj ntawm zoo dua tib yam qhob:

1) Cov dawb kev xaiv ntawm cov xim; 2) solidifies thaum lub sij hawm ib tug ob peb teev; 3) ib tug kuj tsis tshua muaj nqi.
