Asbestos cement yog suav tias yog cov khoom siv hauv tsev muaj txiaj ntsig, uas tau txais kev tsim khoom. Cov khoom siv thev naus laus zis ntawm cov kav dej asbestos-cement nyiam qhov txawv ntawm lawv cov khoom sib tw. Hauv lawv cov khoom siv, xws li cov khoom siv asbestos thiab cement yog siv.
Kev tsim cov khoom lag luam no suav nrog kev siv cov khoom siv Portland cement, uas tsis muaj cov tshuaj ntxiv - M400 thiab M500. Cov txheej txheem tsim khoom suav nrog kev sib xyaw fibers nrog cov cement. Thawj theem yog tsim ntawm lub workpiece. Tom qab ntawd cov yeeb nkab asbestos-cement yog muab tso rau ntawm lub conveyor. Tom qab hardening, nws yog txo mus rau hauv lub pas dej ua ke, thiab nyob rau theem kawg nws yog tig. Asbestos-cement yeeb nkab yog ntau yam khoom uas muaj ntau yam khoom muaj txiaj ntsig.
Tus nqi khoom:
- rot thiab corrosion kuj;
- qis thermal conductivity;
- siab zog;
- tsis nyiam fouling;
- durability;
- reliability;
- nqi qis;
- tawm tsam kev txhoj puab heev.
Fragility tuaj yeem paub qhov tsis txaus.
Asbestos-cement yeeb nkab yog peb hom:
- gas pipeline;
- tap;
- sewer.
Cov kav dej tsis muaj zog yog tsim los ntawm kev tsim khoom. Lawv muaj qhov sib txawv thiab siv rau hauv kev lag luam sib txawv.
Asbestos-cement non-pressure yeeb nkab yog tsim rau sab nraum zoov cov kav dej, cov kav dej phwj tuaj, chimneys, laj kab, cable tso, nrog rau cov kav dej. Nrog kev pab los ntawm cov khoom siv asbestos cement, cov xov tooj cables tau pw. Tsis tas li ntawd, lawv tau siv los ua laj kab ncej thiab hauv kev tsim kho hauv paus. Cov khoom siv siab yog siv rau qhov cua, pa roj, dej, pov tseg thiab melioration.
Txoj Kev Sib Txuas
Txhawm rau txuas cov khoom siv asbestos-cement, couplings, brackets, thiab brackets uas haum rau txoj kab uas hla. Txoj kev siv feem ntau ntawm cov khoom docking. Ua ntej txuas lawv, lub coupling yog rhuab hauv dej kub (90-100⁰С). Tom qab ntawd ib kawg ntawm kev sib txuas yog muab tso rau ntawm cov yeeb nkab uas twb muaj lawm, thiab nws qhov kawg thib ob yog tsau rau ntawm lwm sab. Ntawm cov av ntub dej, kev sib txuas tom qab kev sib txuas tau pom zoo kom ntim nrog cov bitumen kub.
Asbestos-cement yeeb nkab 100 mm inch muaj qhov hnyav ntawm 24 kg, thiab nws qhov ntev yog 3950 mm. Muaj cov khoom ua los ntawm asbestos cement nrog ib txoj kab uas hla ntawm 100 mus rau 500 hli, nrog qhov ntev ntawm 3.95-5 meters. Ib txoj kab uas hla sib txawv nyob ntawm thaj chaw uas siv cov khoom siv hauv tsev. Thaum tsim, nws yog ib qho tseem ceeb los xaiv cov khoom tsim nyog.
Technical requirements rau cov khoom tiav:
- ncaj ntawm cov khoom;
- ua raws li txhua tus qauv xav tau;
- ua raws li cov txheej txheem tiav;
- khoom yuav tsum tsis muaj dej;
- tag nrho cov kav dej yog ntsuas hydraulic siab.
Nws tsis pom zoo kom hloov cov khoom tsis muaj zog nrog lub siab, thiab rov ua dua! Cov kav dej tsis muaj zog asbestos-cement, tus nqi qis me ntsis, txuag nyiaj. Txawm li cas los xij, nws tsim nyog xav tias cov roj yuav tsum tau muab rau hauv qhov siab. Yog tias cov khoom tsis ua raws li cov kev qhia tshwj xeeb, kev sib tsoo yuav tshwm sim.
Lub tshuab tsim khoom ntawm cov khoom no yog tsim tau zoo. Nrog rau cov khoom siv no, cov nqi teeb tsa raug txo los ntawm 50%.
