Pamusoro pemvura, midziyo yakawanda inoshandiswa mu plate heat exchanger imhando ye lean solution, rich solution, sodium hydroxide, sulfuric acid nedzimwe makemikari, izvo zviri nyore kukonzera ngura mu plate uye kuzvimba uye kukwegura kwe gasket.
Plate negasket ndizvo zvinhu zvikuru zve plate heat exchanger, Saka kusarudzwa kweplate negasket zvinhu kwakakosha zvikuru.
Sarudzo yezvinhu zveplate zveplate heat exchanger:
| Mvura yakachena, mvura yerwizi, mafuta anodyiwa, mafuta emaminerari nezvimwe zvinoshandiswa pakugadzira | simbi isina tsvina (AISI 304, AISI 316, nezvimwewo). |
| mvura yegungwa, brine, salinization nezvimwe zvinoshandiswa pakugadzira | titanium uye titanium palladium (Ti, Ti-Pd) |
| Sanganisa sulfuric acid, sanganisa sarufa munyu, inorganic aqueous solution nezvimwe zvinhu | 20Cr, 18Ni, 6Mo (254SMO) nedzimwe alloys |
| Kupisa kwakanyanya uye huwandu hwakawanda hwe caustic soda yepakati | Ni |
| Sulfuric acid yakasimba, hydrochloric acid uye phosphoric acid medium | Hastelloy alloy (C276, d205, B20) |
Sarudzo yezvinhu zve gasket ye plate heat exchanger:
Vanhu vazhinji vanoziva kuti magasket ekuvhara rabha zvinhu zvinoshandiswa zvakanyanya, zvakaita seEPDM, rabha ye nitrile, rabha ye nitrile yakasanganiswa nehydrogenated, fluororubber nezvimwewo.
| EPDM | Tembiricha yebasa iri - 25 ~ 180 ℃. Yakakodzera mvura inopisa zviri pakati nepakati, utsi, ozone yemumhepo, mafuta ekuzora asina petroleum, acid isina simba, base isina simba, ketone, alcohol, ester, nezvimwewo. |
| NBR | Tembiricha yebasa iri - 15 ~ 130 ℃. Yakakodzera zvigadzirwa zvakasiyana-siyana zvemafuta ezvicherwa zvakaita semvura inoyerera, mafuta emafuta akareruka, mafuta ekuzora, mafuta emhuka nemiriwo, mvura inopisa, mvura yemunyu, nezvimwewo. |
| HNBR | Tembiricha yebasa iri - 15 ~ 160 ℃. Yakakodzera mvura inodziya ine tembiricha yepamusoro, mafuta asina kucheneswa, mafuta ane sarufa uye zvinhu zvine sarufa yeorganic, mamwe mafuta anotapurirana kupisa, refrigerant itsva R134a uye ozone environment. |
| FKM | Tembiricha yebasa iri - 15 ~ 200 ℃. Yakakodzera nzvimbo ine mvura, senge sulfuric acid yakakora, caustic soda, heat transfer oil, alcohol fuel oil, acid fuel oil, high-temperature steam, chlorine water, phosphate, nezvimwewo. |
