Kuphatikiza pa madzi, ma TV ambiri omwe amagwiritsidwa ntchito posinthanitsa ndi kutentha kwa mbale ndi njira yowonda, yankho lolemera, sodium hydroxide, sulfuric acid ndi zinthu zina zamankhwala, zomwe ndizosavuta kuyambitsa dzimbiri la mbale ndi kutupa komanso kukalamba kwa gasket.
Plate ndi gasket ndiye zinthu zazikuluzikulu zosinthira kutentha kwa mbale, kotero kusankha kwa mbale ndi gasket ndikofunikira kwambiri.
Kusankhidwa kwa zinthu za mbale ya chosinthira kutentha kwa mbale:
| Madzi oyeretsedwa, madzi amtsinje, mafuta odyeka, mafuta amchere ndi zina | zitsulo zosapanga dzimbiri (AISI 304, AISI 316, etc.). |
| madzi am'nyanja, brine, salinization ndi media zina | titaniyamu ndi titaniyamu palladium (Ti, Ti-Pd) |
| Sulutsani sulfuric acid, chepetsani sulfure mchere wamadzimadzi, organic aqueous solution ndi media zina. | 20Cr, 18Ni, 6Mo (254SMO) ndi ma aloyi ena |
| Kutentha kwakukulu komanso ndende ya caustic soda sing'anga | Ni |
| Anayikira sulfuric asidi, hydrochloric asidi ndi phosphoric asidi sing'anga | Hastelloy alloy (C276, d205, B20) |
Kusankhidwa kwa zinthu za gasket kwa mbale kutentha exchanger:
Anthu ambiri amadziwa kuti ma gaskets osindikiza mphira ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri, monga EPDM, mphira wa nitrile, mphira wa hydrogenated nitrile, fluororubber ndi zina zotero.
| Chithunzi cha EPDM | Kutentha kwa utumiki ndi -25 ~ 180 ℃. Ndi oyenera madzimadzi sing'anga superheated madzi, nthunzi, ozoni mumlengalenga, sanali mafuta zochokera mafuta mafuta, ofooka asidi, ofooka m'munsi, ketone, mowa, ester, etc. |
| NBR | Kutentha kwa utumiki ndi -15 ~ 130 ℃. Ndi oyenera zinthu zosiyanasiyana mchere mafuta monga sing'anga madzimadzi, kuwala mafuta mafuta, mafuta mafuta, nyama ndi masamba mafuta, madzi otentha, madzi amchere, etc. |
| Mtengo wa HNBR | Kutentha kwa utumiki ndi -15 ~ 160 ℃. Ndi yoyenera madzi amadzimadzi otentha kwambiri, mafuta osaphika, mafuta okhala ndi sulfure ndi mankhwala okhala ndi sulfure, mafuta ena otengera kutentha, refrigerant yatsopano R134a ndi chilengedwe cha ozoni. |
| Mtengo wa FKM | Kutentha kwa utumiki ndi -15 ~ 200 ℃. Ndi oyenera sing'anga madzimadzi, monga anaikira sulfuric acid, caustic koloko, kutentha kutengerapo mafuta, mowa mafuta mafuta, asidi mafuta mafuta, mkulu-kutentha nthunzi, chlorine madzi, mankwala, etc. |
