Uyihlanza Kanjani Ithangi le-GFS Elingeni Eliphelele: I-CIP Chemistry kanye Nokuqinisekiswa
Ukuhlanza ithangi le-GFS elisezingeni lokudla kulula ngoba udonga alunazinto eziphilayo: i-enamel ihlanganiswa nensimbi ku-820–930 °C, ihla ngaphansi kuka-0.8 µm Ra, imelana ne-pH 1–14 futhi ayonakali ku-caustic eshisayo. Inqubo ejwayelekile iwukukhipha amanzi, ukugcwalisa ngamanzi okuqala, ukuphinda ujikelezise i-caustic ezingeni lokushisa le-CIP elijwayelekile lesikhungo, ukugcwalisa ngamanzi, bese uhlola indawo ehlolwe nge-spark kanye namajoyinti aboshiwe. Hlala uqinisekisa izinga lokushisa eliphezulu loketshezi nomhwamuko ngokuvumelana nesicaciso, ngoba lezo zinombolo zilawula i-gasket kanye ne-vent, hhayi i-enamel.
Ukuhlanza isitsha senqubo esingagqwali kuwumsebenzi ozilungiselelwe kahle; ukuhlanza igobolondo elikhulu lokugcina akunjalo, futhi yilapho izinkinga ziqala khona. Ithangi likhulu, into yokuhlanza kufanele ifinyelele yonke indawo emanzi ngesiphimbo esisodwa, i-gasket ne-vent kwakungaklanyelwe izinga lokushisa osuzosebenzisa lona, futhi umsebenzi umi phezu kophahla ephethe ithumbu. Izinkinga eziningi zivela ekucabangeni ukuthi into yangaphakathi esezingeni lokudla iziphatha njenge-weld engagqwali kanti akunjalo. Ithangi le-GFS elisezingeni lokudla lihlanza ngenxa yokuqedwa kwendawo kanye nomkhakha wamakhemikhali, futhi lihlanza ngokwezinga elibhaliwe kuphela uma inqubo yayibhalelwe amalunga amaphaneli ne-vent. Ngamanye amazwi umbuzo othi uyihlanza kanjani ithangi le-GFS elisezingeni lokudla uphendulwa ukuqedwa kwendawo kanye nomkhakha wamakhemikhali, inqobo nje uma inqubo ye-CIP yayibhalelwe amalunga amaphaneli ne-vent.
Kungani Indawo ye-Enamel Yenza Ukuhlanza Kube Lula
I-Surface roughness inquma ukuthi udonga ludinga ukuhlanjululwa okungakanani. Ku-tanki ye-GFS esezingeni lokudla, ungqimba lwe-enamel lushiselwa phezu kwephaneli yensimbi ku-820–930 °C futhi luqedwa ngaphansi kuka-0.8 µm Ra, ngakho-ke kuncane kakhulu ukwakheka okuncane okungaba yindawo yokubambelela kwe-milk stone, i-beer stone, i-pectin, i-yeast noma ifilimu yamaprotheni. Leyo yiyona mpawu efanayo evumela ukuthi iphaneli yamukelwe ukuthinta ukudla ngaphansi kwe-FDA ne-LFGB, kanye namanzi aphuzwayo ngaphansi kwe-NSF/ANSI 61 ne-WRAS lapho itanki ligcina amanzi asetshenziswa embonini. I-enamel ayinazinto eziphilayo futhi ayisebenzi ku-pH 1–14, ngakho-ke amakhemikhali e-CIP asetshenziswa embonini—i-caustic, i-nitric noma i-peracetic—awuhlaseli lutho, futhi ayithambi noma i-plasticise uma ukuwashwa kushisa, okuyinto umugqa wezinto eziphilayo obengeza. Izinto ezimbili ezisabangala umonakalo zingokomshini: ukushaywa ngamathroli okuhlanza kanye nokuqhekeka emaphethelweni ephaneli asikwe efektri, yingakho ukuqedwa kwemiphetho kwenziwa efektri hhayi endaweni.
Ukubhala Inqubo Yokuhlanza Ephumelela Ukuhlolwa
Inqubo esemthethweni ibiza amakhemikhali, izinga lokushisa, isikhathi sokujikeleza kanye nesimo sokwamukela. Qala ensaleleni yenqubo — iphrotheni nedwala lobisi kudinga i-caustic; idwala likabhiya ne-oxalate kudinga i-asidi; imvubelo ne-pectin kudinga kokubili. Jikelezisa ezingeni lokushisa elisetshenziswa yisitshalo kakade emishini yalo yensimbi engagqwali, bese uqinisekisa ukuthi izinga lokushisa eliphezulu loketshezi kanye nezinga lokushisa eliphezulu lomhwamuko kungaphakathi kwencazelo, ngoba lezo zinombolo ezimbili zilinganisa isikhala sokukhipha umoya futhi zikhetha inhlanganisela ye-gasket hhayi i-enamel. Hlanza kuze kube yilapho amanzi okukhipha emseleni ecwebile futhi i-pH ibuyela enanini lenqubo, bese urekhoda umphumela. Isimo sokwamukela kufanele sibe ngokubonakalayo: indawo ebushelelezi, eqhubekayo, engafiphele, engenalo uqweqwe, engenawo umhlaba emigqeni yamabhawudi futhi ingenakushintsha kombala emaphethelweni ephaneli, ihlolwe ngesibani kusukela ekhoneni elifanayo njalo ukuze izithombe ziqhathaniseke.
Amajoyinti, Uphahla kanye Nokudonsa Amanzi Emkhakheni Wokuhlanza
Izindawo ezihluleka ukucwaningwa cishe azilona udonga oluyisicaba. Igobolondo eliboshwe ngamabhawudi lihlanganiswa ngamaphaneli acishe abe ngu-1.2 m ububanzi ngamabhawudi ezinga lika-8.8 kanye ne-EPDM gasket, futhi imikhondo ye-gasket iqoqa insalela uma umhlangano ungavalwanga ngokulinganayo; ngakho-ke i-torque nesimo se-gasket kufanele kube yingxenye yohlelo lokuhlanza, futhi noma yiliphi iphaneli elikhishwe ukuze lilungiswe kufanele liphinde lihlolwe nge-spark ku-1500 V DC ngaphambi kokuba libuyiselwe. Ngaphansi kophahla, indawo ebandayo ingagcina i-condensate futhi iconsise insalela yomkhiqizo endaweni ehlanzekile, ngakho-ke uphahla kanye nesigaba esiphezulu kuhlanjwa futhi kuhlolwe ngomjikelezo ofanayo esikhundleni sokukushiya kufike isikhathi sokuvalwa okuphelele okulandelayo. Phansi, iphansi eliyisicaba elinomgudu wokuphuma owodwa lishiya indawo engasebenzi lapho izinto eziqinile ezihlala phansi ziqoqana khona; indawo yedreyini kanye nokuthambekela kuyo kufanele kuhlolwe njalo ngesikhathi sokuhlanza, ngoba ithangi elingakwazi ukuphuma ngokuphelele alikwazi ukuhlanjwa ngokuphelele.
