Vim tus nqi pheej yig thiab zoo, cov ntaub ntawv asbestos-cement tau paub zoo rau cov neeg tsim khoom. Wave cov ntaub ntawv feem ntau yog siv rau vov tsev, thaum lub tiaj tiaj slate tau pom siv nyob rau hauv lwm qhov chaw ntawm kev tsim kho, txawm hais tias nws kuj yog haum rau vov tsev.
Flat slate specifications
Hauv kev tsim cov slate tiaj tus, sib tov ntawm Portland cement nrog asbestos fiber thiab dej yog siv. Qhov sib faib ntawm asbestos, uas yog sib npaug sib npaug hauv nws, yog 18%, vim tias lub hauv paus txhawb nqa ntawm cov ntawv slate yog tsim. Qhov piv ntawm cov khoom no tso cai rau kev tsim cov slate tiaj tus, qhov ntev ntawm qhov sib txawv, resistant rau stretching thiab shock.
Nyob rau hauv kev lag luam, raws li GOST 18124-95, ob hom ca slate yog tsim:
- asbestos-cement unpressed flat;
- asbestos-cement nias tiaj.
Tsis txhob nias lub tiaj tiaj, tsis zoo li nias, muaj zog qis dua thiab tus nqi qis. Nws muaj ib nrab ntawm lub voj voog khov-thaw, uas ua rau nws tsim nyog rau kev ua haujlwm sab hauv. Cov yam ntxwv ntawm slate raug cuam tshuam los ntawm qhov ntau thiab zooasbestos, uas yog ib feem ntawm nws. Yog li, qhov zoo nyob ntawm txoj kab uas hla thiab ntev ntawm fibers, nws cov ntxhia muaj pes tsawg leeg thiab fineness ntawm kev sib tsoo. Tsis tas li ntawd, qhov tsis sib xws ntawm cov slate tiaj tus nyob ntawm qhov xwm txheej thiab cov yam ntxwv ntawm cov khoom siv uas nws tau tsim.
Slate dimensions
Flat slate, qhov ntev ntawm qhov nyob ntawm qhov tuab ntawm daim ntawv, raws li GOST tuaj yeem yog:
- 3600x1500mm nrog daim ntawv tuab 8-10mm;
- 3000x1500mm nrog daim ntawv tuab 8-10mm;
- 2500x1200mm nrog daim ntawv tuab 6-10mm;
Ntxiv rau, qhov sib txawv nruab nrab ntawm qhov dav lossis qhov ntev ntawm daim duab plaub yuav tsum tsis pub tshaj 5 hli. Hauv cov ntawv xovxwm, qhov sib txawv ntawm lub dav hlau kab rov tav yuav tsum tsis pub tshaj 4 hli, rau cov ntawv uas tsis yog nias - 8 hli.
Scope of material
Compressed tiaj tus slate yog siv dav hauv ntau qhov chaw ntawm kev tsim kho. Nws yog siv nyob rau hauv lub fencing ntawm technical shafts thiab ducts, lub installation ntawm formwork nyob rau hauv industrial tej yam kev mob, raws li zoo raws li mus rau sab nraud thiab sab hauv phab ntsa. Hauv kev ua liaj ua teb, slate yog siv rau hauv kev teeb tsa ntawm lub laj kab, kev tsim cov cwj mem rau tsiaj txhu thiab tawb hauv cov nqaij qaib ua liaj ua teb. Cov neeg nyob hauv lub caij ntuj sov thiab cov neeg ua teb kuj feem ntau siv cov khoom siv hauv lawv thaj chaw. Nyob rau hauv kev tsim kho ntawm thaj chaw nyob, tiaj tus slate yog siv rau fencing loggias thiab balconies, txhim kho da dej cabins, thiab lwm yam.
Khoom kom zoo dua:
- durability;
- tus nqi pheej yig;
- tsis kam rau cov khoom zoo li qub (qhov hnyavneeg);
- kev nyab xeeb hluav taws;
- zoo heev suab rwb thaiv tsev los ntawm ntuj phenomena (los nag, lawg);
- tsis muaj hluav taws xob conductivity;
- tsis rot, tsis oxidize;
- tsis xa UV hluav taws xob thiab sib nqus teb;
- saum npoo tsis kub li ntawm lub hnub;
- nws tiv taus khov-thaw, kub hloov pauv.
Txhawm rau tiv thaiv tiaj tus slate, nws yog ib qho tsim nyog yuav tsum tau pleev xim rau tom qab tso, uas yuav ua rau nws lub neej ua haujlwm. Rau cov hom phiaj no, cov xim acrylic yog qhov tsim nyog, uas tsim cov yeeb yaj kiab tiv thaiv rau saum npoo ntawm slate.
