Njengoba sazi, phakathi kwamapuleti e-Plate Heat Exchanger, iTitanium Plate ihlukile ngokumelana kwayo okuhle kakhulu ekugculweni. Futhi ekukhetheni kwe-gasket, i-viton gasket idume ngokumelana ne-acid ne-alkali namanye amakhemikhali. Ngakho-ke ingasetshenziswa ndawonye ukwenza ngcono ukumelana nokugqwala kokushisa ukushisa kwepuleti?
Eqinisweni, ipuleti ye-titanium ne-viton gasket ayikwazi ukusetshenziswa ndawonye. Kodwa kungani? Kungumgomo wokumelana nokonakala kweTitanium le-Titanium Lezi zinto ezimbili ngeke zisetshenziswe ndawonye, ngoba kulula ukwenza i-warder yefilimu eminyene ye-oxium onide evikela ngaphezulu, le filimu ye-oxide ingakhiwa ngokushesha ku-oksijini- equkethe imvelo ngemuva kokubhujiswa. Futhi lokhu kuvumela ukubhujiswa nokulungisa (ukubuyiselwa) kwefilimu e-oxide kugcinwe esimweni esizinzile, ukuvikela izinto ze-titanium ngaphakathi kwala ukubhujiswa okwengeziwe.
Isithombe esijwayelekile sokugqwala
Kodwa-ke, lapho i-titanium Metal noma i-alloy endaweni equkethe i-fluorine, ngaphansi kwesenzo sama-hydrogen ion emanzini, ama-ions we-fluoride kusuka ku-viton gasket asabela nge-titanium yensimbi ukuze akhiqize i-titanium. I-equation yokuphendula imi kanje:
TI2O3 + 6HF = 2TIF3 + 3H2O
Tio2 + 4HF = TIF4 + 2H2O
Tio2 + 2hf = tiof2 + h2o
Ucwaningo luthole ukuthi kwikhambi le-acid, lapho okuhlushwa i-ion ye-fluoride kufinyelela ku-30ppm, ifilimu le-oxidation on titanium ebusweni ingabhujiswa, kukhombisa ukuthi noma ngabe ukugcwala okuphansi kakhulu kwe-fluoride ion kuzonciphisa kakhulu ukumelana nokugqwala kwamapuleti we-titanium.
Lapho i-titanium Metal ngaphandle kokuvikelwa kwe-titanium oxide, endaweni ewonakalisayo equkethe i-hydrogen ye-hydrogen volution, i-titanium izoqhubeka nokuthola i-hydrogen, futhi ukusabela kabusha kwe-redox kwenzeka. Ngemuva kwalokho iTih2 yenziwa kwi-Titanium Crystal ebusweni, esheshisa ukubhujiswa kwe-titanium Plate, yakha imifantu futhi iholele ekuvuzeni kwe-Plate Heat Exchanger.
Ngakho-ke, ePlate Heat Exchanger, i-Titanium Plate kanye ne-Viton Gasket akufanele kusetshenziswe ndawonye, uma kungenjalo kuzoholela ekugcekeni nasekuhlulekeni kokushisa ukushisa kwepuleti.
I-Shanghai Heat Transfer Equipment Co, Ltd. Ukukhetha, ukuqinisekisa ukusebenza okuphephile futhi okuthembekile kwemishini.
