Apho ingasetyenziswa asbestos sheets?

Asbestos sheets ezenziwe asbestos chrysotile nto leyo silicate magnesium bobabo eli qela phyllosilicates. Le ezimbiwa ukumelana bume obrak, kodwa abole xa acid zenze amorphous dust-oda. imali enkulu lwesi sakhi zifumaneka Canada, Russia (Kiembaevskoe kunye Bazhenov idipozithi kwi Urals), China. A indawo ephambili ngokwemiqathango material eluhlaza kufunxwa yeyelizwe lethu.

Nobubi yeemveliso asbestos

Ngokomthetho asbestos sheets Ezinye izihloko ziye okuzenzela leyo abe conductivity ephantsi (ofanelekileyo ukuba abe yedwa), ukumelana eliphezulu ubushushu, inertness ukuba iikhemikhali ezininzi, ozone, ioksijini. izinto resistant Ubushushu (ubushushu yokunyibilika e kuluhlu 1400-1500 degrees) inyanzele kakuhle kunye nezinye izithako. A ethile ebalulekileyo yale nto kukuba xa ukurhogele asbestos uthuli inokuba umhlaza. Ngoko ke, ekwenziweni iimveliso asbestos kufuneka luphunyezwe ngomhla kuluhlu ngokupheleleyo amanyathelo yokhuseleko yabasebenzi.

Xa wenza (nophahla, ubushushu yokugquma, njalo-njalo), ebandakanya asbestos sheets, le nto iphephile, ekubeni imveliso ogqityiweyo yena kwifomu ubotshiwe (ioli, itha, nentlaka, irabha, udaka). Noko ke, amazwe amaninzi bakhetha ukulishiya ngokupheleleyo ukusetyenziswa amasebe. Ngokukodwa, kwi-European Union, amacandelo asbestos wavalwa ngokupheleleyo ukususela ngo-2005, kodwa ke lonke zisetyenziswa mveliso ezininzi.

Asbestos ngohlobo yayo enyulu awusebenzi

Asbestos sheets ziveliswa indibaniselwano kwimicu asbestos okanye izakhi kunye nezinye izinto. Umzekelo, amanqaku asbostalnye ezikhutshwayo GOST 12856-96 kwaye №№ 12586-84, ezenziwe ngocingo isakhelo (tubing) apho lisetyenziswa kumacala omabini iphepha asbolateksnaya grafayithi umphezulu ezisekelwe rubbers zokwenziwa. Zisetyenziswa kwinjini ipetroli okanye idizili njengoko spacers ubungakanani ethile. Iimveliso ezinjalo ukumelana utshintsho ubushushu ukusuka thabatha 60 dibanisa 400, ndachacha emva ucinezelo, unako ukumelana ifuthe zepetroli, iimveliso yokutsha, diesel.

Asbestos ikhadibhodi ezisetyenziswa mveliso ezininzi

Apho ukuthenga amaphepha asbestos ukuze zisetyenziswe ahle kunye nesinyithi non-ayoni? izinto ezinjalo (ibhodi lekrizolite ifayibha based) iqaphelwa ngokusebenzisa kwiivenkile zeentsimbi. Eliphawulwe "KTM" kwaye eveliswa ngokungqinelana GOST № 2850 - 95. Paperboard grade yokwambathisa thermal kufanelekile ukuba uthotho lwemisebenzi kule amandla, ngezobunjineli, Ushishino lweemoto (ngokuba gasket kwi silencers). Ngako oko, enye uxwebhu wavelisa CASS (segama "injongo jikelele asbestos ikhadibhodi"), enokusetyenziselwa usambathisa thermal kwiqondo lobushushu eliphezulu (ukuya degrees 500), izixhobo uphawu le khompawundi abaqeshwe igesi, kwealkali, organic zosasazo.

Indlela iindlela sheet asbhestosi? Ixabiso imveliso ixhomekeke kuhlobo yayo. Ngokomzekelo, iphepha asbostalnoy of ubungakanani obuncinane (0.67 x 0.51 meters) zizakuxabisa malunga ne-mali malunga 550-580 engange. A manqaku evela iibhokisi kunye imilinganiso 1.0 x 0.8 yeemitha iya kuxabisa malunga 400-420 engange.
