Kuwonjezera pa madzi, zinthu zambiri zomwe zimagwiritsidwa ntchito mu plate heat exchanger ndi njira yopanda mafuta, njira yolemera, sodium hydroxide, sulfuric acid ndi zinthu zina zamankhwala, zomwe zimapangitsa kuti plate iwonongeke mosavuta komanso kutupa komanso kukalamba kwa gasket.
Mbale ndi gasket ndi zinthu zofunika kwambiri pa chosinthira kutentha kwa mbale, Chifukwa chake kusankha mbale ndi gasket ndikofunikira kwambiri.
Kusankha zinthu za mbale za chosinthira kutentha kwa mbale:
| Madzi oyera, madzi a m'mitsinje, mafuta odyetsedwa, mafuta a mchere ndi zinthu zina zofalitsa | zitsulo zosapanga dzimbiri (AISI 304, AISI 316, etc.). |
| madzi a m'nyanja, madzi amchere, salinization ndi zina zotero | titaniyamu ndi titaniyamu palladium (Ti, Ti-Pd) |
| Sungunulani sulfuric acid, chepetsani sulfure salt aqueous solution, inorganic aqueous solution ndi zina zotero | 20Cr, 18Ni, 6Mo (254SMO) ndi ma alloys ena |
| Kutentha kwambiri komanso kuchuluka kwa soda yosungunuka | Ni |
| Sulfuric acid yokhazikika, hydrochloric acid ndi phosphoric acid medium | Hastelloy alloy (C276, d205, B20) |
Kusankha zinthu za gasket ya chosinthira kutentha kwa mbale:
Anthu ambiri amadziwa kuti ma gasket otsekera mphira ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri, monga EPDM, mphira wa nitrile, mphira wa nitrile wopangidwa ndi hydrogenated, fluororubber ndi zina zotero.
| EPDM | Kutentha kwa ntchito ndi - 25 ~ 180 ℃. Ndi yoyenera madzi otentha kwambiri amadzimadzi, nthunzi, ozoni wozungulira, mafuta odzola osagwiritsa ntchito mafuta, asidi wofooka, maziko ofooka, ketone, mowa, ester, ndi zina zotero. |
| NBR | Kutentha kwa ntchito ndi - 15 ~ 130 ℃. Ndi yoyenera zinthu zosiyanasiyana zamafuta amchere monga mafuta osungunuka, mafuta opepuka, mafuta opaka, mafuta a nyama ndi ndiwo zamasamba, madzi otentha, madzi amchere, ndi zina zotero. |
| HNBR | Kutentha kwa ntchito ndi - 15 ~ 160 ℃. Ndi yoyenera madzi apakati otentha kwambiri, mafuta osaphika, mafuta okhala ndi sulfure ndi mankhwala ena okhala ndi sulfure, mafuta ena osinthira kutentha, firiji yatsopano R134a ndi malo okhala ndi ozoni. |
| FKM | Kutentha kwa ntchito ndi - 15 ~ 200 ℃. Ndi yoyenera kugwiritsa ntchito madzi monga sulfuric acid, caustic soda, mafuta osinthira kutentha, mafuta a mowa, mafuta a asidi, nthunzi yotentha kwambiri, madzi a chlorine, phosphate, ndi zina zotero. |
