Hurukuro pamusoro pesarudzo yeflange gasket (IV)

Iko kushandiswa kweasbestos rubber sheet muindasitiri yekuvhara mavharuvhu kune zvinotevera zvakanakira:

Mutengo wakaderera: Kana uchienzaniswa nezvimwe zvinhu zvekuisa chisimbiso zvakanyanya, mutengo weasbestos rubber sheet unokwanisika.

Kemikari kuramba: Asbestos rabha sheet ine yakanaka corrosion kuramba kune imwe svikiro ine hunyoro hwemakemikari zvimiro, izvo zvinogona kuzadzisa zvinodiwa zveyakajairwa mamiriro ekushanda.

Kugadziriswa kuri nyore: Nekuti iyo asbestos rubber sheet iri nyore kugadzirisa uye kutsiva, iri nyore pakuchengetedza valve.

Dambudziko guru reasbestos rubber sheet nderekuti kunyange iyo gasket zvinhu inowedzerwa nerubha uye mamwe mafirita, haisati yakwanisa kuzadza zvachose ma pores madiki anobatana, uye pane trace kupinda. Naizvozvo, munzvimbo inosvibisa zvakanyanya, kunyangwe kudzvanywa uye tembiricha zvisina kukwirira, hazvigone kushandiswa. Kana ichishandiswa mune mamwe anopisa-kupisa kwemafuta midhiya, kazhinji munguva inotevera yekushandiswa, nekuda kwecarbonization yerabha uye yekuzadza, simba rinodzikiswa, zvinhu zvinova zvakasununguka, uye pane kupinda mukati meiyo interface uye mukati me gasket, uye kune kubika uye kusvuta. Mukuwedzera, iyo asbestos rubber sheet inosungirirwa nyore nyore kune flange yekuisa chisimbiso pamusoro pekushisa kwepamusoro, izvo zvinounza dambudziko rakawanda pakutsiviwa kwegasket.

Kune mvura yekristaro uye mvura yakashambadzirwa mune asbestos fiber zvinhu. Pa110 ℃, 2/3 yemvura yakashambadzirwa pakati pemafiber yakave yakawedzera, uye kusimba kwekusimba kwemafiber kunoderedzwa neanenge 10%. Pa 368 ℃, mvura yese yakashambadzirwa inobuda, uye simba rekusimba refiber rinodzikiswa ne20%. Pamusoro pe500 ℃, mvura yecrystalline inotanga kunaya, uye simba rakaderera.

Asbestos rabha sheet rine chloride ions uye sulfide, zviri nyore kuumba corrosion galvanic masero ane simbi flanges mushure mekunyura kwemvura, kunyanya iyo sulfur yemukati yemafuta-inodzivirira asbestos rabha sheet yakakwira kakawanda kupfuura iyo yakajairwa asbestos rubber sheet, saka haina kukodzera. kuti ishandiswe mune zvisiri zvemafuta. Magasi achazvimba mumafuta uye zvinonyungudutsa midhiya, asi mukati meimwe nhanho, hapana chakanyanya kukanganisa pakuita chisimbiso.

Zvisinei, zvakakosha kuziva kuti asbestos yakaonekwa sechinhu chine ngozi, uye kushandiswa kweasbestos rubber sheets kunogona kupa njodzi dzinogona kuitika kune hutano uye zvakatipoteredza.
