ʻO ka hoʻohana ʻana i ka pepa asbestos rubber i ka ʻoihana sealing valve he mau pono kēia:

Ke kumu kūʻai haʻahaʻa: Ke hoʻohālikelike ʻia me nā mea hana hoʻopaʻa inoa kiʻekiʻe, ʻoi aku ka maʻalahi o ke kumu kūʻai o ka pepa asbestos rubber.

Ke kū'ē kemika: He kū'ē ka corrosion maikaʻi ka pepa ʻōpala asbestos no kekahi ʻano me nā waiwai kemika maʻalahi, hiki ke hoʻokō i nā pono o nā kūlana hana maʻamau.

Mālama maʻalahi: No ka mea maʻalahi ka hana a me ka hoʻololi ʻana o ka pepa asbestos rubber, ʻoi aku ka maʻalahi no ka mālama ʻana i ka valve.

ʻO ka pilikia nui loa o ka pepa asbestos ʻo ia ʻoiai ua hoʻohui ʻia ke kinoea me ka lāʻau a me kekahi mau mea hoʻopiha, ʻaʻole hiki ke hoʻopiha piha i nā pores liʻiliʻi e hoʻopili ai, a aia ka trace penetration. No laila, i loko o ka mea hoʻohaumia nui, ʻoiai inā ʻaʻole kiʻekiʻe ke kaomi a me ka mahana, ʻaʻole hiki ke hoʻohana ʻia. Ke hoʻohana 'ia i loko o kekahi kiʻekiʻe-mehana aila media, maʻamau i ka hope manawa o ka hoʻohana 'ana, ma muli o ka carbonization o ka pulupulu a me ka filler, ua hoemiia ka ikaika, ka mea lilo i mea wehe, a me ke komo ana ma ka interface a me loko o ka gasket, a aia ka coking a me ka uahi. Eia hou, ua hoʻopaʻa maʻalahi ka pepa asbestos i ka flange sealing surface ma ke kiʻekiʻe wela, kahi e lawe mai ai i ka pilikia nui i ka hoʻololi ʻana o ka gasket.

I ka moku'āina wela, pili ke kaomi o ka gasket ma nā ʻano media like ʻole i ka ikaika o ka paʻa ʻana o ka mea gasket. Aia ka wai aniani a me ka wai adsorbed i loko o nā mea asbestos fiber. Ma 110 ℃, 2/3 o ka wai adsorbed ma waena o nā fibers ua hoʻoheheʻe ʻia, a ua hoʻemi ʻia ka ikaika tensile o nā fiber ma kahi o 10%. Ma 368 ℃, hoʻoheheʻe ʻia ka wai adsorbed a pau, a hoʻemi ʻia ka ikaika tensile o ka fiber ma kahi o 20%. Ma luna o 500 ℃, hoʻomaka ka wai crystalline e kahe, a emi ka ikaika.

Loaʻa i ka ʻōpala asbestos nā ion chloride a me ka sulfide, maʻalahi e hana i nā pūnaewele galvanic corrosion me nā flanges metala ma hope o ka absorption wai, ʻoi aku ka nui o ka sulfur maʻiʻo o ka ʻaila-kūpaʻa asbestos rubber sheet ma mua o ka pepa asbestos maʻamau, no laila ʻaʻole kūpono ia no ka hoʻohana ʻana i ka media non-oily. E pehu nā Gaskets i ka ʻaila a me ka media solvent, akā i loko o kekahi ʻano, ʻaʻohe hopena i ka hana sila.

Eia nō naʻe, pono e hoʻomaopopo ʻia ua ʻike ʻia ka asbestos ma ke ʻano he mea pōʻino, a ʻo ka hoʻohana ʻana i nā ʻāpana asbestos hiki ke hōʻeha i ke olakino a me ke kaiapuni.
