Industrial High Temperature Gasket Material

Maindasitiri akakwira-temperature gasket material chinhu chakanyatsogadzirirwa kuti chizadzike chakavimbika munzvimbo-yetembiricha yepamusoro (kazhinji zvichireva tembiricha yekushanda inodarika 120 degrees , uye mune dzimwe nguva dzakanyanyisa, dzinosvika 1000 degrees kana kudarika). Basa rayo repakati ndere kuchengetedza kunaka kwakanaka, kuisa chisimbiso, uye kugadzikana kwechimiro pasi pekupisa kwakanyanya, kudzvanywa kwepamusoro, uye zvinogona kukanganisa zvepakati mamiriro, kudzivirira mvura kana gasi kubuda. Izvo zvikamu zvakakosha zvekushanda kwakachengeteka kwemidziyo yeindasitiri.
Maindasitiri akakwira-tembiricha yegasket zvinhu zvine hunyanzvi uye zvine chekuita nekuvimbika kwekuvharisa, kuchengetedza, uye mitengo yekushandisa yemidziyo.

Tembiricha parameters:Zvinodiwa kutsanangura zvakajeka tembiricha yenguva refu-yekushanda uye tembiricha-yenguva pfupi (sekukwira kwepakarepo-tembiricha kana mudziyo uchitanga kana kumira), uye sarudza zvinhu zvine tembiricha inopikiswa nepamusoro 20% kusvika 30% kumusoro pane tembiricha chaiyo (chengetedza margin). Semuenzaniso, mumamiriro ezvinhu apo tembiricha yekushanda iri 250 dhigirii kwenguva yakareba, zvinhu zvine tembiricha yekupikisa yeGreater than kana yakaenzana ne300℃zvinofanirwa kusarudzwa.

Hunhu huri pakati nepakati:Paunenge wasangana nemafuta media (senge hydraulic mafuta, dhiziri), dzivirira silicone rubber uye EPDM. Isa mberi fluororubber kana simbi ronda gaskets (akazadzwa graphite). Kana uchinge wasangana nezvinosvibisa midhiya (senge sulfuric acid uye caustic soda), magirafu anoumba gaskets kana nickel alloy metal gaskets anofanirwa kupihwa pekutanga. Kana wasangana nechikafu kana mishonga yezvemishonga, zvinhu zvinosangana neFDA certification (sechikafu-grade silicone rabha, pure graphite) inofanira kusarudzwa.

Pressure mamiriro:Low pressure (< 1MPa). Rubber or asbestos-free gaskets are available as options. For medium and high pressure (1 to 30MPa), metal wound or corrugated gaskets are preferred. Ultra-high pressure (>30MPa) inoda kupfekedzwa kwesimbi kana simbi yakachena gaskets (senge mhangura kana aluminium gaskets).

Fomu rekuvhara:Dynamic sealing (senge pistons, inotenderera shafts) inoda zvakanyanya elastic zvinhu (senge fluororubber); Kune static yekuisa chisimbiso (senge maflange uye zvishandiso zvekushandisa), composite fiber kana simbi gaskets inogona kusarudzwa.

Kuisa uye mutengo:Magetsi eRubber neasbestos{0}emahara ari nyore kuisa uye ane mutengo wakaderera, asi hupenyu hwawo hupfupi. Metal gaskets inoda kufananidzwa nechaiyo flange nzvimbo (pamusoro roughness Ra Less than kana kuenzana ne3.2μm), iyo inodhura, asi ine hupenyu hurefu hwebasa uye kuvimbika kwakanyanya.
