Ngaphezu kwamanzi, iningi lezinto ezisetshenziswa ku-plate heat exchanger yisisombululo esingenamafutha, isisombululo esicebile, i-sodium hydroxide, i-sulfuric acid kanye nezinye izinto zamakhemikhali, okulula ukubangela ukugqwala kweplate kanye nokuvuvukala kanye nokuguga kwe-gasket.
Ipuleti kanye ne-gasket kuyizinto eziyinhloko ze-plate heat exchanger, Ngakho-ke ukukhethwa kwezinto zepuleti kanye ne-gasket kubaluleke kakhulu.
Ukukhetha izinto zepuleti ze-plate heat exchanger:
| Amanzi ahlanzekile, amanzi omfula, uwoyela odliwayo, uwoyela wamaminerali kanye neminye imithombo yezindaba | insimbi engagqwali (AISI 304, AISI 316, njll.). |
| amanzi olwandle, usawoti, usawoti kanye neminye imithombo | i-titanium ne-titanium palladium (Ti, Ti-Pd) |
| Nciphisa i-sulfuric acid, nciphisa isixazululo samanzi esinosawoti wesibabule, isixazululo samanzi esingaphili kanye neminye imithombo | 20Cr, 18Ni, 6Mo (254SMO) kanye nezinye izinhlobo ze-alloys |
| Izinga lokushisa eliphezulu kanye ne-caustic soda medium ehlushwa kakhulu | Ni |
| I-asidi ye-sulfuric egxilile, i-hydrochloric acid kanye ne-phosphoric acid medium | Ingxubevange ye-Hastelloy (C276, d205, B20) |
Ukukhetha izinto ze-gasket ze-plate heat exchanger:
Iningi labantu liyazi ukuthi ama-gasket okuvala irabha ayizinto ezisetshenziswa kakhulu, njenge-EPDM, irabha ye-nitrile, irabha ye-nitrile ene-hydrogenated, i-fluororubber njalo njalo.
| I-EPDM | Izinga lokushisa lesevisi lingu-25 ~ 180 ℃. Lifanele amanzi afudumele kakhulu aphakathi nendawo, umusi, i-ozone yomoya, uwoyela wokugcoba ongasekelwe ku-petroleum, i-acid ebuthakathaka, isisekelo esibuthakathaka, i-ketone, utshwala, i-ester, njll. |
| I-NBR | Izinga lokushisa lesevisi lingu-15 ~ 130 ℃. Lifanele imikhiqizo ehlukahlukene kawoyela wamaminerali njenge-fluid medium, uwoyela kaphethiloli olula, uwoyela wokugcoba, uwoyela wezilwane nowemifino, amanzi ashisayo, amanzi anosawoti, njll. |
| I-HNBR | Izinga lokushisa lesevisi lingu-15 ~ 160 ℃. Lifanele amanzi aphakathi nendawo anokushisa okuphezulu, uwoyela ongahluziwe, uwoyela oqukethe isibabule kanye nezinto eziphilayo eziqukethe isibabule, amanye amafutha okudlulisa ukushisa, i-refrigerant entsha i-R134a kanye nendawo ye-ozone. |
| I-FKM | Izinga lokushisa lesevisi lingu-15 ~ 200 ℃. Lifanelekela indawo ewuketshezi, njenge-sulfuric acid egxilile, i-caustic soda, uwoyela wokudlulisa ukushisa, uwoyela kaphethiloli wotshwala, uwoyela kaphethiloli we-acid, umusi oshisa kakhulu, amanzi e-chlorine, i-phosphate, njll. |
