Flat slate yog asbestos-cement slab ua los ntawm kev siv tshuab tshwj xeeb. Cov khoom siv no muaj ntau yam kev siv ntau yam. Feem ntau nws yog siv rau hauv kev lag luam, vaj tse thiab kev lag luam. Cov yam ntxwv ntawm cov slate tiaj tus yog siab heev. Ntawm nws cov zoo zoo yog lub zog, durability, hluav taws kev ruaj ntseg, yooj yim ntawm installation. Cov khoom siv yog tsim los ntawm ntau qhov sib txawv, uas feem ntau nyob ntawm nws hom thiab txoj kev thov.
Npaj slate production
Vim tias lub ntsiab tseem ceeb hauv kev tsim cov slate tiaj tus yog asbestos, nws tsim nyog tham txog nws ua ntej. Cov khoom siv raw no tau siv nyob rau hauv ntau yam kev tsim kho rau ntau tshaj li ib puas xyoo, nrog rau nws cov kev pab ntau yam ntawm cov qauv tsim. Asbestos yog lub hauv paus chiv keeb. Nws yog qhov txawv los ntawm cov fibers uas muaj zog heev, tshaj nyob rau hauv lub zog txawm steel hlau. Cov khoom los ntawm nws ua ke zoo heev thiab qisnqi.
Hauv kev tsim cov slate tiaj tus, cov khoom hauv qab no yog siv:
- chrysotile-asbestos;
- portland cement;
- dej.
Qhov feem ntawm asbestos nyob rau hauv no muaj pes tsawg leeg yog 18%. Thaum tsim ib daim ntawv, nws cov fibers yog sib npaug ntawm tag nrho cov cheeb tsam. Lawv ua raws li cov cement mortar thiab ua ib qho kev txhawb nqa mesh. Ua tsaug rau lub hauv paus no, tiaj tus slate, daim ntawv loj uas tau txiav txim siab thaum pib molding, muaj zog tensile zog, muaj zog cuam tshuam, hluav taws kub thiab lwm yam zoo.
Scope of application
Flat slate muaj ntau yam kev siv ntau dua li nws cov corrugated counterpart. Nws yog feem ntau siv hauv kev ua liaj ua teb, kev lag luam thiab kev tsim kho vaj tse. Nrog kev pab los ntawm cov ntaub ntawv no formwork rau lub hauv paus thiab "qhuav screeds" yog ua. Thaum lub sij hawm tsim kho, cov phab ntsa yog tsim los siv cov txheej txheem sandwich vaj huam sib luag thiab lub sam thiaj railings. Tsis tas li ntawd, tiaj tus slate, daim ntawv qhov ntau thiab tsawg ntawm qhov sib txawv, yog tsim rau kev npaj vov tsev, sab nrauv thiab sab hauv kho kom zoo nkauj ntawm cov tsev.
Ntau zaus, cov slabs yog siv los ua laj kab. Nyob rau hauv kev ua liaj ua teb, sheds, gazebos, aviaries, cwj mem thiab lwm yam outbuildings yog tsim los ntawm lawv. Hauv kev lag luam, tiaj tus slate kuj tau siv. Nrog nws cov kev pab, laj kab yog erected, technical shafts lined, pem teb yog nteg. Feem ntau cov qauv me me tau teeb tsa los ntawm cov khoom siv no, piv txwv li, khw muag khoom lossis pavilions.
Ntau yam tiaj tus slate
Nyob ntawm kev tsim tshuab ntawm slate tiaj tus, nws tau muab faib ua ob hom: nias thiab tsis nias. Cov ntaub ntawv no txawv ntawm ib leeg hauv lawv cov yam ntxwv. Piv txwv li, flat pressed slate daim ntawv qhov ntev thiab qhov hnyav yog loj dua unpressed. Nws lub zog yog me ntsis siab dua, nrog rau tus nqi. Lub voj voog ntawm kev khov thiab thawing ntawm cov khoom siv no yog ob zaug ntev, thiab qhov kev ua yuam kev hauv cov kab tawm qhov ntev yog tsawg dua. Kev kam rau siab rau nias slate yog 4 hli, thaum uas tsis yog nias slate nws yog 8 hli.
Qhov sib txawv ntawm cov khoom sib txawv kuj tseem nyob hauv lawv qhov chaw thov. Flat unpressed slate, daim ntawv qhov ntev me me, yog siv rau cladding vaj tse, txhim kho sab hauv partitions, thiab teem insulated phab ntsa panels. Cov khoom siv nias yog siv rau kev tsim cov khoom siv hluav taws xob, kev teeb tsa hauv pem teb slabs, vov tsev, laj kab.
Txhua hom slate yog qhia los ntawm qhov sib txawv, piv txwv li: LP-P-3, 6x1, 5x8 GOST. Cov tsiaj ntawv nyob rau hauv nws yog deciphered raws li nram no:
- LP - daim ntawv tiaj tus;
- NP or P - unpressed or pressed.
Tus lej qhia hauv lub cim qhia:
- ntev, ntawv dav hauv meters;
- slate thickness in millimeters.
Specifications
Cov yam ntxwv ntawm cov slate tiaj tus mus rau qhov loj tshaj yog nyob ntawm cov cuab yeej siv tshuab,siv nyob rau hauv kev tsim khoom, nrog rau cov ntsiab lus tseem ceeb ntawm cov khoom siv raw - asbestos. Tshwj xeeb, cov hauv qab no cuam tshuam rau qhov zoo ntawm cov khoom:
- ntom ntawm asbestos-cement pob zeb;
- kab thiab nruab nrab fiber ntau ntev;
- tshuaj thiab mineralogical muaj pes tsawg leeg;
- sib tsoo fineness.
Tus nqi ntawm asbestos nyob rau hauv qhov muaj pes tsawg leeg thiab qhov sib xws ntawm kev faib tawm ntawm nws cov fibers hauv cov cement kuj cuam tshuam rau lub tiaj tiaj. Daim ntawv loj, specifications thiab lwm yam khoom ntawm cov khoom nyob ntawm seb nws hom. Saib cov lus sib piv kom paub meej:

- yuav yooj yim thiab teeb tsa;
- tus nqi qis.
Asbestos-cement cov khoom muaj lub zog siab. Lawv tuaj yeem yooj yim txhawb qhov hnyav ntawm tus neeg. Qhov zoo no yog tus yam ntxwv los ntawm ob qho tib si wavy khoom thiab tiaj tus slate. Daim ntawv qhov ntev, yoj thiab lwm yam kev hloov kho tsis cuam tshuam rau lub zog.
tsis zoo ntawm cov khoom
Flat slate, ntxiv rau ntau qhov zoo, muaj qee qhov tsis zoo.
- Qhov muaj asbestos nyob rau hauv cov khoom muaj feem xyuam rau nws cov phooj ywg ib puag ncig. Txhawm rau tiv thaiv koj tus kheej thaum ua haujlwm nrog slate tiaj tus, koj yuav tsum siv kev tiv thaiv ua pa.
- Vim cov dej tsis zoo thaum lub sijhawm ua haujlwm, cov khoom yuav dhau los ua cov moss. Txhawm rau zam qhov no, thaum txiav thiab tso, nws yuav tsum tau kho nrog cov cuab yeej tshwj xeeb.
- Slate flat sheet size yog impressive, thiab yog li ntawd hnyav heev. Piv txwv li,ib lub phaj nrog qhov ntev ntawm 1.75x1.12 m thiab tuab ntawm 8 hli muaj qhov hnyav txog 30 kg. Qhov no ua rau muaj teeb meem hauv kev thauj thiab tso cov khoom.
Dimensions asbestos-cement sheets
Slate flat sheet size yuav txawv. Txhua daim hlau yog duab plaub. Deviations los ntawm geometric qhov ntev yog ua tau, tab sis tsis ntau tshaj 5 hli. Qhov hnyav nyob ntawm qhov ntev thiab hom khoom. Cov kev xaiv tau muaj nyob hauv cov lus:
| Length, mm | dav, mm | Thickness, mm | Nyhav, kg |
| 3600 | 1500 | 8-10 | 70-115 |
| 3000 | 1500 | 8-10 | 59-96 |
| 2500 | 1200 | 6-10 | 39-64 |
| 2000 | 1500 | 6-10 | 48-80 |
| 1750 | 1130 | 6-10 | |
| 1500 | 1000 | 6-10 |
Kuj feem ntau muaj cov slate tiaj tus, daim ntawv qhov ntev yog: 1750x1130, 1500x1000, 600x400 mm.
Flat slate yog cov khoom siv zoo heev hauv kev tsim kho. Thaum xaiv nws, koj yuav tsum tau xyuam xim rau lub cim,mus yuav ib yam khoom uas nws zoo tagnrho rau koj.
