Qhob mix

Heavy qhob yog siv thaum txhim kho phab ntsa thiab cov plag tsev ntawm lub tsev vaj tse thiab muaj vaj tse. Hnav qhob yog feem ntau siv rau rwb thaiv tsev (thermal rwb thaiv tsev ntaub ntawv).

Yuav ua li cas hom ntawm cov qauv no yog lub pob zeb sib tov, ua vaj tse zoo nyob.
Qhob Cheebtsam - dej, muab tub lim, phau ntawv (li ib txwm lub npe - MAAs) additives. Sis ntawm phau ntawv thiab dej ua rau ib tug tshuaj cov tshuaj tiv thaiv, txoj kev ua dua tshiab compound, saib zoo li ib tug nplaum khob noom cookie. Cov builders hu ua nws ib txoj kev kuaj ntawm MAAs, los yog xis mas grout. Nws nchuav muab tub lim. Cov MAAs muab tshuaj txhuam yog thinly tsho tiv no lub muab tub lim hais thiab binds lawv (peculiar cev pob txha yog tsim, uas tiv thaiv deformation thiab shrinkage nyob rau hauv lub neej yav tom ntej). Tom qab ua tiav solidification ntawm lub pob zeb ua mix yuav khoom monolithic pob zeb.

Nyob rau sau ua ib pawg (crushed pob zeb, gravel, xuab zeb (los yog ib tug sib tov thereof) tso nyiaj rau txog 80% ntawm lub ntim, txawm li cas los, cov xov tooj tej zaum yuav hloov. Los ntawm yog ib feem ntawm ib tug qhob mix yuav yog nyob ntawm seb dab tsi lub pob zeb ua tshwm sim nyob rau hauv (ib lub zog, Thaum tshav kub kub-resistant, khaub-ncaws nyias, tam ., thiab lwm yam), txawm li cas los, nws tsis yog ib txwm tau mus ntxiv lub caij nyoog proportions, tshwj xeeb tshaj yog yog hais tias tus builder - homegrown pib xyaum ua.

Qhuav qhob mix, npaj yuav tej zaum qhov zoo tshaj plaws tshuaj. Qhov no semi-tiav lawm cov khoom nrog rau cov tshuaj ntawm MAAs thiab sau ua ib pawg feem, diluted nrog dej thiab do ncaj qha mus rau qhov kev siv ntawm qhov chaw. Qhuav qhob mix yuav khaws cia rau ib ntev lub sij hawm thiab tsuas yog noj raws li yuav tsum tau, tsis muaj kev hloov lub zog, xws li npaj txhij-mix.

Lug siv thiab qhuav siv mixtures. Qhov no koom haum pab cov ntaub ntawv nrog tshwj xeeb zog, advantageously siv nyob rau hauv xov (hmoov xim tsev, textured coatings, "kua wallpaper" thiab al.). Ntau mixtures (rau masonry mortars, cov nplaum rau cov iav thiab pobzeb, muab tub lim, leveling tebchaw, compositions sanation) combines cov phau ntawv puag. Qhov no npaj txhij compositions yog sufficiently diluted nrog dej, nrog ib tug heev xis "specialization" zog hloov additives (plasticizing, stabilizing uas hloov ntawm qhov chaw kawm thiab hardening ceev, dej ntsuab, kev sib khi, dej-repellent, bactericidal, huab cua entraining, etc.).

Thiab yog hais tias lub feem ntau tsis ntev los no siv tau rau cov xov pob zeb ua sib tov (ntau precisely, cov tshuaj ntawm cov xuab zeb thiab xis mas), tab sis tam sim no ntau thiab ntau kom nws qhuav hmoov sib tov rau kev thov khaubncaws sab nraud povtseg mus rau ib tug centimeter thiab tshaj. Maas - ib tug mineral phau ntawv, yog zoo tagnrho rau cov compression thiab raug khaws xuab zeb nws "pab". Tab sis xws li ib tug tov yog tsis ib txwm mas dabtsi yog khoov thiab tensile kev nyuaj siab (tshwj xeeb tshaj yog yog tias nyias txheej). Dej tuav peev xwm no mas tsis tshua: dej soaks mus rau hauv lub hauv av thiab sai sai suab kuj sai sai, uas tsis pub cov kawg MAAs co, uas ua nyob rau hauv txo durability. Cov kev siv ntawm qhuav mixtures ntawm cov raug muaj.

Cov mixtures raug muab faib ua gypsum, txiv qaub, gypsum, limestone, MAAs thiab xis mas-txiv qaub. Muab tub lim tej zaum yuav av limestone, fibers (mineral, organic), marble tej daim, lub tsev xuab zeb, hlau fiber. Cov ntaub ntawv npaj: rau screeds thiab nws tus kheej-leveling plag tsev, pobzeb, masonry, plastering. Tshwj xeeb tebchaw siv:

- strengthening ntawm lub hauv paus;
- sealing ntawm cov pob qij txha;
- kov ntub thiab salted phab ntsa;
- ib tug waterproofing;
- Txum Tim Rov Qab tej hauj lwm (kho kom zoo nkauj);
- kho kev ua hauj lwm (putty mixtures).

Nyob ntawm seb lub hom hauj lwm thiab xaiv tau cov tsim nyog cov ntaub ntawv uas. Ntawm tag nrho cov tebchaw muab kev koom tes nyob rau hauv kev tsim kho, lub pob zeb mix yuav siv sij hawm txog 30-40%, thiab qhuav hmoov sib tov rau hauv lub tshuav 60-70%.
