Ntawm kev ua lag luam niaj hnub no muaj kev xaiv loj ntawm ntau yam sib xyaw ua tiav kom tiav. Cov kws tsim txuj ci nyiam npaj cov kev daws teeb meem no ntawm lawv tus kheej.

Thaum kho cov phab ntsa sab hauv thiab sab nrauv, sib xyaw asbestos-cement tau siv . Nws tuaj yeem npaj tsis tau tsuas yog los ntawm cov cement, tab sis kuj yog xuab zeb, thiab txawm tias av nplaum, qhov tseem ceeb yog kom paub qhov sib piv. Nyob ntawm qhov muaj pes tsawg leeg, nws tuaj yeem teeb tsa sai dua lossis qeeb dua. Qee zaum asbestos-cement mortar yog siv rau kev ua kom tiav qhov cub, vim nws khaws cov cua sov zoo.

Khoom

Kev sib xyaw asbestos-cement muaj tus lej ntawm tus yam ntxwv zoo, uas yog vim li cas nws thiaj li nquag siv hauv kev tsim kho. Cov tshuaj khib yog yas, muaj lub zog tensile zoo.

Asbestos muab tshuaj txhuam yog ruaj khov thiab muaj ntau yam . Muab rau hauv hnab, qhuav. Txhawm rau tsim kev daws teeb meem, koj yuav tsum tau siv dej.

Xws li cov cement txheej yog ruaj, tiv taus kub subzero, tsis muaj dej thiab tsis txhawb kev sib txuas.

Sib xyaw

Cov asbestos-cement sib tov muaj 70% ntawm cov cement, thiab koj yuav tsum xaiv cov khoom qib tsawg kawg 400. Cov fiber nws tus kheej tsuas yog 30%. Dej ntxiv hauv qhov nyiaj ntawm 10% los ntawm qhov hnyav ntawm qhov sib tov. Nov yog qhov GOST tswj hwm.

Qhov sib xyaw ua ke yuav muaj gypsum, txiv qaub, av nplaum

Cov muaj pes tsawg leeg sib txawv nyob ntawm seb cov phab ntsa (sab hauv lossis sab nrauv) ua tiav.

Sab hauv phab ntsa

Txiv qaub

Rau qhov sib xyaw no, siv cov txiv qaub ua paj thiab xuab zeb, uas tuaj yeem yog 1 txog 5 ntu. Thaum ntxiv dej, txhua yam yog sib xyaw kom huv. Txhawm rau zam kom tsis txhob muaj pob zeb, ntxiv cov xuab zeb ntxiv. Zuag qhia tag nrho sib xws yuav tsum ze rau ntawm lub khob noom cookie.

Qhov sib tov tau npaj tshwj xeeb rau hnub ntawd.

Txiv qaub-gypsum

Ntxiv nrog rau cov khoom siv uas tau teev tseg yav dhau los, siv gypsum. Ua ntej, npaj ib lub khob noom cookie plaster. Nws yog ib qho yooj yim ua, tsuas yog ncuav qhov sib tov qhuav rau hauv dej, nplawm. Tom qab ntawd cov khoom lag luam tau sib xyaw nrog cov kua txiv qaub kom txog thaum tau txais cov homogeneous loj.

Ib feem yuav tsum yog me me, raws li cov muaj pes tsawg leeg teeb tsa sai

Yog tias koj ua dej ntau dhau, tom qab ntawd cov tshuaj yuav qhuav ntev dua, thiab txheej nws tus kheej yuav xoob vim qhov tshwm sim.

Cement-txiv qaub

Noj rau ua noj:

• xis mas;
• txiv qaub;
• xuab zeb.

Hauv thawj theem, cov xuab zeb thiab cov cement tau sib xyaw ua ke, tsuas yog tom qab ntawd cov kua txiv qaub tau nchuav. Qhov sib piv yog 1: 1: 10, qhov twg cov cement, txiv qaub thiab cov xuab zeb mus raws li qhov xav tau.

Lub ntsej muag

Cov xuab zeb tau npaj ua ntej. Qhov huv nws yog, qhov ua tiav zoo dua. Cement qib 400 raug coj los, ntxiv rau hauv qhov sib piv ntawm 1: 4, qhov twg 4 ntu yog xuab zeb. Yog tias siv M500, ces qhov kev faib ua feem kuj hloov pauv - 1: 5. Yog tias koj tsis ua raws li qhov yuav tsum tau ua, koj tau txais cov tshuaj tsis haum.

Thaum tsim khoom, cov khoom sib xyaw qhuav tau sib xyaw thiab tsuas yog tom qab ntawd ntxiv dej

Qhov txiaj ntsig zoo tshaj plaws yog qhov sib xws ntawm tuab qaub cream.

Txiv qaub

Hauv qee kis, cov kua qaub hloov pauv rau cov cement. Qhov no tsis cuam tshuam qhov ua tau zoo ntawm cov khoom tiav. Tsuas yog siv cov txiv qaub uas tsis muaj pob txha siv xwb. Ua ntej, xuab zeb tau muab tso rau hauv qab, tom qab ntawd dej tau ntxiv thiab tsuas yog tom qab cov txiv qaub ntawd.

Av nplaum

Qhov sib tov no yog siv cov cement, xuab zeb thiab txiv qaub. Tsuas yog nrog lawv ua cov ntaub ntawv tsim nyog rau kev kho kom zoo nkauj. Ib txhia ntxiv gypsum.

Cov av nplaum yog pre-soaked hauv dej . Qhov nruab nrab, txoj haujlwm no siv sijhawm txog 3 teev. Txhawm rau tiv thaiv cov av nplaum kom qhuav, koj yuav tsum tau ntxiv dej. Thaum nws tau txais cov tuab ntawm qaub cream, koj tuaj yeem siv nws.

Tam sim no nws yog lub sijhawm ntxiv 0.2 feem pua cov cement. Sib tov txhua yam thiab ntxiv me ntsis xuab zeb . Rau 1 qhov av nplaum, koj yuav tsum tso 0.3 feem ntawm cov txiv qaub, uas yog siv tsis yog xuab zeb.

Thov

Asbestos-cement mortar yog siv ua rwb thaiv tsev ntawm phab ntsa thiab tsis yog. Ua tsaug rau cov tawv ntoo, nws muaj peev xwm khaws tau cua sov . Nws tsis raug rau cov dej noo. Asbestos fibers ua rau lub ntsej muag du, thiab yog tias koj plaster phab ntsa tom qab, cov kab nrib pleb yuav tsis tshwm.

Tsis tshua muaj, tab sis nws tshwm sim tias cov tshuaj asbestos tau siv rau cua sov rwb thaiv tsev ntawm cov raj xa dej lossis cov qhov cua nkag mus . Cov sib xyaw no muaj cov ntsiab lus asbestos siab. Kev sib xyaw tau siv, yog tias tsim nyog, txhawm rau ntxiv dag zog rau cov pob qij txha ntawm cov kav dej ua los ntawm tib asbestos.

Ntawm lwm yam, kev daws teeb meem tuaj yeem siv ua cov muab tub lim thaum tso cov kav dej ntsaws . Ua tsaug rau nws, cov pob qij txha muaj kev ywj pheej ntau dua.

Sab hauv thiab sab nrauv kuj tuaj yeem npog nrog asbestos-cement mortar. Nws kuj yog siv rau qhov cub.

Kev npaj

Asbestos cement tuaj yeem ua los ntawm txhais tes yog tias koj paub qhov sib piv. Rau qhov cub siv:

• gypsum hmoov;
• av nplaum;
• asbestos.

Qee zaum cov xuab zeb lossis fiberglass tau siv los ua tus muab tub lim.

Yog tias gypsum siv los ua cov khoom siv tseem ceeb, tom qab ntawd ua ke nrog fiberglass, txiv qaub thiab xuab zeb, qhov sib piv yuav tsum yog 1: 0, 2: 2: 1.

Av nplaum kuj tseem tuaj yeem yog cov muab tub lim tseem ceeb, tom qab ntawd nws tau siv nrog cov xuab zeb ib nrab. Cov rog ntawm cov av nplaum ua lub luag haujlwm tseem ceeb. Qhov sib xyaw ua ke yuav tsum yog khov, txwv tsis pub nws yuav tsis yooj yim rau nws txhawm rau phab ntsa.

Cov av nplaum tuaj yeem yog cov hom hauv qab no:

• asbestos, xuab zeb, av nplaum - 0, 1: 2: 1;
• xis mas, av nplaum, asbestos, xuab zeb - 1: 1: 0, 1: 2;
• txiv qaub, asbestos, av nplaum, xuab zeb - 1: 0, 1: 1: 2.

Txhua qhov sib xyaw ntawm asbestos thiab xis mas yog cov khoom siv ruaj khov, tshwj xeeb. Nws tau siv los ua cov khoom lag luam zoo li cov kav dej thiab slate 20 xyoo dhau los.

Ua tau ntev thiab ntseeg tau - qhov no yog qhov sib txawv ntawm cov tshuaj khib nrog asbestos ua ntej.
