Cov khoom tshwj xeeb ntawm asbestos ua rau nws tuaj yeem siv cov khoom no hauv ntau hom kev lag luam. Yeej, qhov no yog kev tsim cov khoom siv asbestos-cement uas siv rau kev tsim kho, nrog rau kev tsim khoom nkoj, foob pob ua ntxaij tsev, mechanical engineering, automotive, electrochemical, chemical, tsheb laij teb thiab aviation industries.
Daim ntawv asbestos yog cov khoom siv uas siv tau los ua cov rwb thaiv tsev zoo rau thaj chaw ntawm txhua lub hom phiaj. Daim ntawv asbestos, tus nqi uas tsis yog siab dhau, tuaj yeem siv tsis tau tsuas yog hauv kev lag luam, tab sis kuj rau kev xav tau ntawm tus kheej. Cov ru tsev feem ntau yog npog nrog cov ntawv zoo li no. Hauv nws qhov chaw tsim khoom, txhua qhov yuav tsum tau ua ntawm GOST rau kev siv nyab xeeb thiab txhim khu kev qha raug coj mus rau hauv tus account.
Daim ntawv asbestos muaj cov qauv fibrous, uas muab cov khoom zoo thermal rwb thaiv tsev.
Qhov tseem ceeb ntawm kev siv cov khoom siv no feem ntau yog vim muaj peev xwm tiv thaiv hluav taws ntawm lub tsev. Cov khoom no tiv taus qhov kub thiab txias thiab tuaj yeem ua qhov thaiv kom qhib nplaim taws.
Tseem cov khoom noyuav raug siv rau kev sib khi kev sib txuas ntawm kev sib txuas lus, cov khoom siv, nrog rau cov khoom siv thiab thermal rwb thaiv tsev ntawm cov kav dej lossis cov chav kub kub.
Nws muaj peev xwm yuav daim ntawv asbestos rau cov haujlwm me me ntawm cov khw muag khoom, tab sis tom qab kev yuav khoom nws yog ib qho tseem ceeb kom khaws nws kom zoo. Txhawm rau kom tsis txhob degradation ntawm cov khoom ua tau zoo, nws yog ib qho tsim nyog yuav tsum tau khaws cia rau hauv qhov chaw kaw, qhuav, kom tsis txhob muaj dej los ntawm cov khoom siv.
Asbestos yooj yim heev los lis thiab tsis tas yuav muaj kev txawj ntse lossis cov cuab yeej siv los siv. Nyob rau tib lub sijhawm, cov qauv ntawm asbestos tau txais txiaj ntsig nrog cov nqi siab ntawm kev ua haujlwm ntev, kev ntseeg tau thiab lub zog vim nws qhov zoo sib xws nrog pob zeb.
Asbestos cardboard muaj ntau qhov zoo, ntawm cov hauv qab no tsim nyog qhia:
- kub ua haujlwm txog li 500 degrees yam tsis muaj khoom siv hluav taws xob;
- siv sijhawm ntev;
- cov qauv zoo;
- tsis loj hlob pwm thiab tsis npog nrog fungus, vim nws tiv taus cov kab mob lom.
Asbestos cardboard tuaj yeem ua cushioning thiab rau kev siv dav.
Daim ntawv asbestos yog tsim nyob rau hauv cov qib hauv qab no, raws li qhov ruaj GOST 2850-95:
- CAON -1. Cov ntaub ntawv asbestos rau lub hom phiaj dav dav nrog qhov ntsuas kub txog li 500 degrees;
- CAON-2. Ua hauj lwm raws li ib tug sealant rau cov khoom thiab cov cuab yeej. Nws kuj muaj kev txwv kub rau cov pa roj - txog li 500 g, cov organic tebchaw - mus txog 400 g, tib yam kev txwv rau ntsev tov thiab melts,alkalis - txog 200 g., thiab inorganic acids - mus txog 120 g. Celsius.
- PAK - cushioning cardboard ua los ntawm asbestos. Siv raws li ib tug mos core nyob rau hauv ua ke seals. Cov no feem ntau yog lub tog raj kheej blocks ntawm diesel thiab carburetor cav.
Daim ntawv asbestos yog tsim nrog tus qauv qhov ntev ntawm 1000x800 mm, txawm li cas los xij, lub thickness ntawm daim ntawv yuav txawv: los ntawm ob millimeters mus rau ib centimeter. Lub thickness nyob ntawm qhov hluav taws kub tsis kam ntawm cov khoom.
