Nkuko tubizi, mu mapine y’icyuma gihindura ubushyuhe bw’amapine, plate ya titanium ni umwihariko kubera ko irwanya ingese neza. Kandi mu guhitamo gasket, gasket ya viton izwiho kurwanya aside na alkali n’ibindi binyabutabire. None se bishobora gukoreshwa hamwe kugira ngo byongere ubudahangarwa bw’icyuma gihindura ubushyuhe bw’amapine?
Mu by’ukuri, plate ya Titanium na gasket ya viton ntibishobora gukoreshwa hamwe. Ariko kuki? Ni ihame ryo kurwanya ingese rya plate ya titanium ko ibintu bibiri bidashobora gukoreshwa hamwe, kuko plate ya titanium yoroshye gukora urwego rwa filtre y’uburinzi bwa titanium oxide hejuru y’ubutaka, uru rwego rwa filtre ya oxyde rushobora gukorwa vuba mu bidukikije birimo ogisijeni nyuma yo kwangirika. Kandi ibi bituma kwangirika no gusana (gusubiramo) filtre ya oxyde bikomeza kuba mu buryo buhamye, birinda ibintu bya titanium imbere mu kwangirika kurushaho.
Ishusho isanzwe y'ingufu ziterwa n'imiyoboro
Ariko, iyo icyuma cya titaniyumu cyangwa aloyine biri mu kirere kirimo fluorine, bikozwe na iyoni za hydrogen mu mazi, iyoni za fluoride zikomoka kuri gasket ya vitoni zigirana na titaniyumu y'icyuma bigatuma fluoride isomba, bigatuma titaniyumu ihinduka. Ingano y'ibisubizo ni iyi ikurikira:
Ti2O3+ 6HF = 2TiF3+ 3H2O
TiO2+ 4HF = TiF4+ 2H2O
TiO2+ 2HF = TiOF2+ H2O
Ubushakashatsi bwagaragaje ko mu gisubizo cya aside, iyo igipimo cya fluoride ion kigeze kuri 30ppm, agace ka oxidation ku buso bwa titanium gashobora kwangirika, bigaragaza ko nubwo igipimo cya fluoride ion cyagabanuka cyane bizagabanya cyane ubudahangarwa bwa titanium.
Iyo icyuma cya titaniyumu kidakingiwe na okiside ya titaniyumu, mu kirere cyangiritse kirimo hidrojeni ya hidrojeni, titaniyumu izakomeza kwinjiza hidrojeni, maze REDOX iratangira gukora. Hanyuma TiH2 ikorerwa ku buso bwa kristu ya titaniyumu, yihutisha kwangirika kwa titaniyumu, igakora imikaka bigatuma ikigega cy’ubushyuhe cya plate kivamo.
Bityo rero, muri plate exchanger, titanium plate na viton gasket ntibigomba gukoreshwa hamwe, bitabaye ibyo bizatuma plate exchanger igenda yangirika kandi ikarangire.
Shanghai Heat Transfer Equipment Co., Ltd. (SHPHE) ifite uburambe bwinshi mu nganda zihindura ubushyuhe bwa plate, kandi ifite na laboratwari zijyanye nabyo zijyanye na physique na chemical, zishobora kumenya vuba kandi neza ibikoresho bya plate na gasket ku bakiriya mu ntangiriro zo guhitamo, kugira ngo ikore neza kandi mu buryo bwizewe ibikoresho.
