Njengoko sisazi, phakathi kweepleyiti zokutshintsha ubushushu kwipleyiti, ipleyiti ye-titanium yodwa ngenxa yokumelana kwayo nokugqwesa. Kwaye ekukhethweni kwe-gasket, i-viton gasket idume ngokuxhathisa i-asidi kunye ne-alkali kunye nezinye iikhemikhali. Ke ngaba zinokusetyenziswa kunye ukuphucula ukuxhathisa komhlwa kwi-plate heat exchanger?
Enyanisweni, i-Titanium plate kunye ne-viton gasket ayinakusetyenziswa kunye. Kodwa kutheni? Ngumgaqo wokuxhathisa umhlwa wepleyiti yetitanium ukuba ezi zinto zimbini azinakusetyenziswa kunye, kuba ipleyiti yetitanium kulula ukwenza umaleko wefilimu exineneyo yetitanium oxide ekhuselayo kumphezulu, lo maleko wefilimu oxide inokwakheka ngokukhawuleza kwioksijini- equlethe imeko-bume emva kokutshatyalaliswa. Kwaye oku kuvumela ukutshatyalaliswa kunye nokulungiswa (ukubuyisela kwakhona) ifilimu ye-oxide ukuba igcinwe kwisimo esizinzileyo, ukukhusela izinto ze-titanium ngaphakathi kwifomu yokutshatyalaliswa ngakumbi.
Umfanekiso oqhelekileyo wokutya
Nangona kunjalo, xa isinyithi se-titanium okanye i-alloy kwindawo ene-fluorine, phantsi kwee-ion ze-hydrogen emanzini, i-ion ze-fluoride ezivela kwi-viton gasket zisabela nge-metal titanium ukuvelisa i-fluoride enyibilikayo, eyenza i-titanium pitting. I-reaction equation imi ngolu hlobo lulandelayo:
Ti2O3+ 6HF = 2TiF3+ 3H2O
TiO2+ 4HF = TiF4+ 2H2O
TiO2+ 2HF = TiOF2+ H2O
Uphononongo lufumene ukuba kwisisombululo se-acidic, xa i-ion ye-fluoride ifikelela kwi-30ppm, ifilimu ye-oxidation kumphezulu we-titanium inokutshatyalaliswa, ebonisa ukuba nokuba i-concentration ephantsi kakhulu ye-ion ye-fluoride iya kunciphisa kakhulu ukuxhatshazwa kwe-corrosion yamacwecwe e-titanium.
Xa isinyithi se-titanium ngaphandle kokukhuselwa kwe-titanium oxide, kwindawo engcolileyo equlethe i-hydrogen ye-hydrogen evolution, i-titanium iya kuqhubeka ifunxa i-hydrogen, kwaye i-REDOX isabela. Emva koko i-TiH2 iveliswa kumphezulu wekristale ye-titanium, ekhawulezisa ukubola kwepleyiti ye-titanium, yenze iintanda kwaye ikhokelela ekuvuzeni kwe-plate exchanger heat.
Ngoko ke, kwi-plate exchanger heat, i-titanium plate kunye ne-viton gasket akufanele isetyenziswe kunye, ngaphandle koko iya kukhokelela ekudlekeni kunye nokungaphumeleli kwe-plate heat exchanger.
I-Shanghai Heat Transfer Equipment Co., Ltd.(SHPHE) inamava enkonzo etyebileyo kwishishini lokutshintshiselana kobushushu kwipleyiti, kwaye ineelabhoratri ezihambelanayo zomzimba nezekhemikhali, ezinokukhawuleza nangokuchanekileyo ukumisela imathiriyeli yepleyiti kunye negasket kubathengi abakwinqanaba lokuqala ukhetho, ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo kwezixhobo.
