Asbestos yog hu ua cov ntxhia pob zeb dawb, lossis ntau dua, pawg ntawm cov nplua nuj fiber ntau. Lub pob zeb no yog siv hauv ntau qhov kev lag luam. Muaj ob hom asbestos: amphibole thiab chrysotile. Chrysotile asbestos yog nrov dua. Yuav ua li cas nws txawv ntawm amphibole analogue, peb yuav qhia ntxiv.
Khoom nta
Cov yam ntxwv tseem ceeb ntawm cov khoom yog durability thiab alkali tsis kam. Thiab asbestos tsis hlawv txhua. Cov cuab yeej no tau paub nyob rau hauv ancient Egypt. Lawv paub txog qhov no hauv Tebchaws Europe ib yam nkaus: Charles V tau hais kom xaws ntaub pua rooj los ntawm asbestos fibers thiab muaj kev lom zem, cov qhua xav tsis thoob los ntawm kev cuam tshuam cov khoom nrog rau cov khoom seem hauv qhov hluav taws kub. Cov zaub mov tau kub hnyiab, tab sis daim ntaub ntaub tseem nyob tsis huv.
Ntxiv rau, chrysotile asbestos muaj cov khoom hauv qab no:
- YElasticity.
- siab zog.
- Heat resistance. Ntawm qhov kub siab tshaj +700 degrees, cov pob zeb fibers ua nkig, thiab ntawm + 1500 degrees lawv pib yaj.
- Tsawg hluav taws xob thiab thermal conductivity.
- Explosion pov thawj.
- Hluav taws kub resistant.
- Kev nyab xeeb: thaum cua sov, cov khoom siv tsis tso cov tshuaj phem rau cov kab mob nyob.
Asbestos kuj muaj adsorption reinforcing thiab spinning zog.
Cov khoom siv
Chrysotile asbestos tau muab faib ua ob peb pawg, nyob ntawm seb cov khoom muaj pes tsawg leeg muaj. Kev sib cais yuav siv qhov chaw ntawm cov cuab yeej tswj, ntawm qhov tshwj xeeb sieves. Txhua lub sieve muaj qhov sib txawv mesh:
- 12.7mm;
- 4.8mm;
- 1, 35mm;
- 0.4mm.
Ntxiv mus, cov khoom raug muab faib ua 7 pawg raws li qhov loj ntawm qhov tau txais feem. Pawg 6 yog suav tias yog qhov xav tau tshaj plaws, qhov no yog chrysotile asbestos qib K-6-30, K-45, K-20, K-5. Nws yog siv los tsim cov khoom siv asbestos-cement:
- Cov nplooj ntawv Wavy. Muaj cov ntawv wavy thiab tiaj tus.
- Extrusion panels rau phab ntsa thiab ru tsev.
- Muab faib rau sab nrauv thiab sab hauv phab ntsa hauv cov tsev thiab cov qauv.
Scope of application
Chrysotile asbestos tau dav siv vim nws yuav luag cov khoom tshwj xeeb. Nrog nws:
- Ua cov rwb thaiv tsev thermal ntawm cov khoom siv cua sov, qhov cub.
- Bricking chav boilers.
- Tshuaj asbestos-cement thiab asbestos khoom.
- Muab cov rwb thaiv tsev kub rau cov khoom nkhaus.
- Tiv thaiv cov qauv hlau los ntawm qhov kub thiab txiasetc.
Chrysotile kuj tseem siv rau hauv daim ntawv, tsheb, kev kho mob thiab iav kev lag luam.
Chrysotile asbestos qib K-6-30: specifications
Cov khoom muaj cov khoom nram qab no:
- Kub tiv thaiv txwv - 500 ° C.
- pib yaj ntawm 1500 ° C.
- Density index - 2.6 g/cm3.
- Alkalinity - txog 10.2 pH.
- 0, 8 - coefficient ntawm kev sib txhuam.
- Lub zog tensile Performance index yog tshaj 3000 MPa.
Ntim, tsheb thauj mus los, cia
Chrysotile asbestos tau ntim rau hauv cov khoom hluavtaws lossis cov hnab ntawv. Qhov hnyav ntawm lub hnab yog 50, 45 lossis 40 kg. Kev thauj mus los yog ua tau los ntawm txhua txoj kev thauj mus los. Qhov tsuas yog mob rau qhov no yog lub peev xwm ua raws li cov txheej txheem ntawm kev thauj khoom / tshem tawm. Tsis tas li ntawd, lub load yuav tsum ruaj khov. Rau kev thauj mus los ntawm kev tsheb ciav hlau, nws raug nquahu kom txav cov khoom hauv cov khoom thauj khoom thauj mus rau kev siv lub peev xwm wagon ntau tshaj plaws.
Yuav kom cov khoom khaws tag nrho nws cov tshuaj, nws yuav tsum muab khaws cia rau hauv daim ntawv ntim. Nws yog ntshaw kom cov chaw siv rau qhov no raug kaw. Yog tias qhov chaw cia yog qhov chaw qhib lossis cov txheej txheem raug tshem tawm, nws yog ib qho tsim nyog uas cov chrysotile yuav tsum tau ntim rau hauv cov hnab hluavtaws, thiab npog nrog cov khoom siv dej tsis zoo rau sab saum toj los tiv thaiv nws los ntawm ya raws. Yog li cov khoom tuaj yeem khaws cia tau ntev, tab sis tsis pub ntau tshaj ib xyoos txij li hnub tsim khoom.
