Gukoresha urupapuro rwa asbestos mu nganda zifunga valve bifite ibyiza bikurikira:

Igiciro gito: Ugereranyije n'ibindi bikoresho byo gufunga bifite imikorere myiza, igiciro cy'urupapuro rwa asbestos ruhendutse cyane.

Ubudahangarwa bw'imiti: Icupa rya asbestos rifite ubudahangarwa bwiza bwo kwangirika ku buryo bumwe na bumwe bufite imiterere yoroheje ya shimi, ishobora guhaza ibisabwa mu mikorere rusange.

Gusana byoroshye: Kubera ko urupapuro rwa asbestos rworoshye gutunganya no gusimbuza, biroroshye cyane kubungabunga valve.

Ikibazo gikomeye cy’urupapuro rwa asbestos ni uko nubwo ibikoresho bya gasket byongewemo rubber na bimwe mu byuzuza, ntibishobora kuzuza neza utwenge duto duhuza, kandi hari aho binjira. Kubwibyo, mu buryo bwanduza cyane, nubwo igitutu n'ubushyuhe bitari hejuru, ntibishobora gukoreshwa. Iyo bikoreshejwe mu byuma bipima amavuta bishyuha cyane, akenshi mu gihe cyo gukoreshwa nyuma, bitewe no kuba rubber na filler bivamo karubone, imbaraga ziragabanuka, ibikoresho birarekura, kandi hari aho binjira mu gice cy’imbere no mu cyuma, kandi hari aho bikonjesha n'umwotsi. Byongeye kandi, urupapuro rwa asbestos rufatwa byoroshye ku buso bufunga flange ku bushyuhe bwinshi, ibyo bikaba bitera ibibazo byinshi mu gusimbuza gasket.

Mu gihe cy'ubushyuhe, umuvuduko wa gasket mu buryo butandukanye uterwa n'uko imbaraga z'ibikoresho bya gasket zigumana. Hari amazi ya kristu n'amazi yakuwemo mu bikoresho bya fibre ya asbestos. Kuri 110℃, 2/3 by'amazi yakuwemo hagati y'imigozi biba byaragabanutse, kandi imbaraga zo gukurura za fibre zigabanukaho 10%. Kuri 368℃, amazi yose yakuwemo arasohoka, kandi imbaraga zo gukurura za fibre zigabanukaho 20%. Hejuru ya 500℃, amazi ya kristu atangira kugwa, kandi imbaraga ziba nke.

Urupapuro rwa asbestos rugizwe na iyoni za kloride na sulfide, byoroshye gukora uturemangingo twa galvanic dukoresheje ibyuma nyuma yo kwinjiza amazi, cyane cyane ko ingano ya sulfure iri mu rupapuro rwa asbestos rudakoresha amavuta iruta inshuro nyinshi ugereranyije n'urupapuro rusanzwe rwa asbestos, bityo ntirukwiriye gukoreshwa mu bikoresho bitari amavuta. Gaskets ziyongera mu bikoresho bya peteroli n'ibinyabutabire, ariko mu rugero runaka, nta ngaruka zigira ku mikorere yo kuzifunga.

Ariko, ni ngombwa kumenya ko asbestos yagaragaye ko ari ikintu kibi, kandi gukoresha impapuro za asbestos bishobora guteza ingaruka mbi ku buzima no ku bidukikije.
