Kumboda asbestos machira Vamwe nyaya vane fibers vane pasi conductivity (yakanakira voga), mukuru kupisa nemishonga, inertness kune mishonga yakawanda, ozone, okisijeni. Heat nemishonga zvinhu (utsotso kutonhora zviri kuwanda 1400-1500 madhigirii) anotsinga zvakanaka zvimwe zvinhu. A chinokosha drawback izvi zvinhu ndechokuti kana inhaled asbestos guruva kungava carcinogenic. Saka, muna zvaAtemisi asbestos zvigadzirwa zvinofanira chinozoiswa pamusoro zvizere zvakawanda basa kudzivirira matanho.

Kana tichiita (nemakadhibhokisi, kupisa kuputira, etc.), inosanganisira asbestos machira, mashoko aya anonzi yakachengeteka, sezvo rapera chigadzirwa ari munhu akasungwa chimiro (namafuta, bhitumini, Inogadzirwa nemasiridzi anobuda mumiti, rabha, purasita). Zvisinei, nyika dzakawanda vanosarudza kusiya zvachose kushandisa kwakadaro zvinoriumba. Zvikurukuru muna European Union, asbestos zvinoriumba zvakarambidzwa zvachose kubva 2005, asi vamwe nyika anoshandiswa mumaindasitiri zhinji.

Asbestos ayo yakaisvonaka chimiro haushandi

Asbestos machira anobudiswa neZvapupu ibatanidzo asbestos fibers kana zvinhu nevamwe zvinhu. Somuenzaniso, nyaya asbostalnye rakapa maererano GOST 12856-96 uye №№ 12586-84, akagadzirwa waya puranga (Perforated) icho rinoshandisirwa kumativi maviri bepa pamwe asbolateksnaya graphite pamusoro yakavakirwa chakaita zvokugadzirwa rubbers. Ivo zvinoshandiswa peturu kana Diesel injini sezvo spacers vamwe saizi. zvinogadzirwa zvakadai angakudzivisai tembiricha kuchinja kubva kubvisa 60 kuwedzerazve 400, akapora pashure compression, angakudzivisai matambudziko peturu, combustion zvigadzirwa, Diesel chinotsva.
