Embonini yensimbi, ukugcina ukusebenza kahle ngesikhathi senqubo yokukhetha insimbi kubalulekile ekususeni isikali se-oxide kanye ne-tint yokushisa, ukuqinisekisa izingxenye zensimbi ezingenasici ezisezingeni eliphezulu. Kodwa-ke, izindlela zendabuko zokukhetha insimbi, ezithembele ekwelashweni kwamakhemikhali njenge-hydrochloric (I-HCl) noma i-sulfuric acid, ngokuvamile ihlushwa imiphumela engahambisani ngenxa yezixazululo ze-asidi ezonakele kanye nokuntuleka kokuqapha ngesikhathi sangempela. Lokhu kuholela ekungasebenzini kahle, amanani aphezulu okwenqatshwa, kanye nezinselele ezibizayo zokuthobela i-EPA.
I-Lonnmeterimitha yokuminyana kwe-asidi esemgqeniiyi-game-changer esebenzisa ubuchwepheshe be-ultrasonic ngokuqhubekayoIsilinganiso se-acid density online. Idizayinelwe izitshalo zokukhetha insimbi nochwepheshe, le mitha yokuminyana kwe-asidi esemgqeni inikezela ngokunemba okunganaso ukukhukhuleka, izinto ezimelana ne-asidi, kanye nokuhlanganiswa kokuzenzakalela okungenamthungo. Isinyathelo esiphusile ekuthuthukiseni ikhwalithi nokusebenza kahle kwamabhizinisi okukhiqiza insimbi, izikhungo zokucubungula insimbi ezingenayo ayoni, izindawo zokukhiqiza izinto ezithwalayo neziqinisayo, izitshalo ze-electroplating, imigqa yokukhiqiza ye-anodizing, izitshalo ezikhiqiza i-wafer, izimboni zebhodi lesekethe eliphrintiwe (PCB), abakhiqizi bezinto zamakhemikhali, izitshalo zokugaywa kabusha kwensimbi nezivuselelayo.
Ukwazi Kwezobuchwepheshe
Nakuba i-passivation ithuthukisa ukumelana nokugqwala kwezingxenye zensimbi engagqwali, iyasilela ekubhekaneni nokungapheleli okuthile kokukhiqiza. Isibonelo, ayikususi i-tint yokushisa noma isikali se-oxide esiwumphumela wezinqubo zokushisela nokushisa. Ngokomlando, lezi zinkinga ziye zasingathwa ngenqubo eyengeziwe yamakhemikhali eyaziwa ngokuthi “i-pickling.”
Indlela I-Stainless Steel Pickling Esebenza Ngayo
I-Pickling isebenza njengendlela yokwelapha yangaphambi kokudlula, lapho izingxenye zensimbi engagqwali zicwiliswa kusixazululo se-asidi—imvamisa i-hydrochloric noma i-sulfuric acid—ukuze kuncibilike isikali se-oxide, i-tint yokushisa, nezinhlayiya zensimbi ezishumekiwe. Kodwa-ke, le nqubo yokukhetha insimbi ayinembile ngokwemvelo, iveza izinselele ezifana nemithetho eqinile ye-EPA kanye nemiphumela engaguquki. Njengoba ikhambi le-asidi liguga, ukusebenza kwalo kuncipha, kanye nezinga lokususwa kwempahla lingahluka kakhulu, kube nzima imizamo yokugcina ikhwalithi efanayo enqubweni yokukhetha insimbi.
Izinselele Ezibalulekile Ekugadweni Kokugeza Kokugeza Okuxubile
Ukuqapha okugeza okufakwe emgqeni kuyisici esibalulekilesteel pickling inqubo, nokho iza namaphuzu obuhlungu amaningana angaphazamisa ukusebenza kahle kanye nekhwalithi kupickling metal inqubo kanye HCL pickling inqubo. Enye inselele enkulu ukuntuleka kwedatha yesikhathi sangempela, njengoba izindlela ezivamile ezifana nokusampula okwenziwa ngesandla nokuhlaziya ilebhu engaxhunyiwe ku-inthanethi (isb., ukubhala amagama) zethula ukubambezeleka kwemizuzu eyi-10-30. Lokhu kubambezeleka kuvame ukuholela ekukhetheni ngokweqile, okubangela ukugqwala kwe-hydrogen ensimbi enamandla amakhulu, noma ukuvuthwa kancane, okushiya isikali se-oxide singaguquki futhi kwandise amazinga okulahlwa afika ku-15%.
Enye inkinga ebalulekile ukuwohloka kwezixazululo ze-asidi ngokuhamba kwesikhathi. Imvelo eyonakalisayo yamabhavu okukha amanzi iphinde ibeke engcupheni imishini yokuqapha, ngezinzwa zendabuko ezifana namamitha we-glass density ezinqotshwa ukonakala, kudingeke ukuthi kushintshwe njalo nokunakekelwa, okungase kuphumele ekwenyukeni kwezindlekoinqubo pickling amakhemikhaliizinkulungwane ngonyaka.
Ukuthobela imvelo kungeza ubunkimbinkimbi obengeziwe, njengoba imithetho ye-EPA idinga ukulawulwa okuqinile kwenkungu ye-asidi nokulahlwa kwemfucuza. Ukuqapha okungalungile kungaholela ekwephuleni umthetho, ukufaka izinhlawulo kanye nokwelashwa kwe-asidi kadoti kube nzima. Ukwengeza, ukuhlukahluka kokususwa kwezinto kwenza kube nzima ukuzuza ikhwalithi yendawo efanayo. Ukubhekana nala maphuzu obuhlungu kudinga isisombululo esiqinile njenge-imitha ye-acid density ye-inthanethiukuqinisekisa ukunemba nokuzinza kwenqubo.
Izinzuzo Zokwethula I-Inline Acid Density Meter
Ukuguqula Ukusebenza Nokunemba Ekukhetheni I-Acid
Ukwethulwa kwemitha yokuminyana kwe-asidi esemgqeni, njengesixazululo esithuthukisiwe se-Lonnmeter, kushintsha inqubo yokucosha insimbi ngokuhlinzeka ngesilinganiso se-asidi sesikhathi sangempela ku-inthanethi. Lobu buchwepheshe buqinisekisa ukuthi ukugxilwa kwe-asidi kugcinwa ngaphakathi kwebanga elifanele, kuvimbele ukukha kakhulu okungase kubangele ukugqwala kwe-hydrogen noma ukucutshungulwa okuncane okushiya isikali se-oxide singaguquki. Ngokuqapha amashifu okuminyana okubangelwa ukunqwabelana kwe-ion yensimbi, imitha ibangela ukulungiswa okuzenzakalelayo.
Ukonga Izindleko Nokuthembeka Kokusebenza
Ukusebenzisa i-acid density meter emgqeni iletha izinzuzo ezinkulu zezindleko, ukunciphisa ukusetshenziswa kwamandla. Ngokuhlanganisa nezinhlelo ze-PLC/DCS ngemiphumela engu-4-20 mA noma RS485, imitha yenza ngokuzenzakalelayo ukugcwalisa i-asidi nokuphathwa kwemfucuza.
Ukuthobela Imvelo Nokuguquguquka
Imitha yokuminyana kwe-asidi ku-inthanethi isekela ukuthobela imvelo ngokugcina amazinga enkungu ye-asidi ngaphansi kwemikhawulo ye-EPA, ukugwema izinhlawulo nokwenza lula ukwelashwa kwe-asidi kadoti. Ukuguquguquka kwayo kudlulela ezinqubweni ze-batch, lapho ihlola khona ukuphela komjikelezo we-asidi, kanye nezinhlelo zokwelashwa kwemfucuza.
Ukulawulwa Kwenqubo Okuthuthukisiwe kanye Nokulungela Ikusasa
Ngale kwezinzuzo ezisheshayo, imitha yokuminyana kwe-asidi esemgqeni inika amandla ukulawulwa kwenqubo yokubikezela ngokuthola amathrendi kudatha yokuminyana, okuvumela ochwepheshe ukuthi balindele ukuwohloka kwe-asidi noma izinkinga zemishini ngaphambi kokuba zikhule. Kuhlanganiswe ne-automation, kunciphisa ukungenelela okwenziwa ngesandla, kukhulula abasebenzi ukuthi bagxile emisebenzini yamasu. Ezimbonini zokukhetha insimbi ezicabangela phambili, lobu buchwepheshe busekela ukuthuthukiswa kwangokwezifiso kwe-OEM/ODM kanye nokusebenzisana kwe-R&D, kuqinisekisa ukufinyelela emisha esezingeni eliphezulu.
Imibuzo Evame Ukubuzwa
Imitha ye-asidi esemgqeni ithuthukisa kanjani inqubo yokukhetha?
Imitha yokuminyana kwe-asidi esemgqeni ihlinzeka ngedatha yesikhathi sangempela yenqubo yokukhetha i-asidi, igcine ukugxilisa ingqondo kahle, ithuthukisa ukusebenza kahle nokuqinisekisa ukuqedwa kwensimbi okuthobela i-ASTM.
Ingabe ingakwazi ukumelana nezimo ezibucayi zokukhetha?
Yebo, izinzwa ze-Hastelloy ezimelana ne-asidi ezingaphakathi kumugqa wemitha nempilo ende ziyenza ifanelekele izimo zensimbi zokugqwala, ingilazi yomdabu engapheli noma amathuluzi epulasitiki.
Ingabe ukuhlanganiswa nezinhlelo ezikhona kungenzeka?
Impela, imitha yokuminyana kwe-asidi ku-inthanethi isekela i-4-20 mA kanye nezivumelwano ze-Modbus, ezihlanganisa ne-PLC/DCS yokulawula inqubo yokukhetha insimbi ezenzakalelayo, ukunciphisa ukungenelela okwenziwa ngesandla.
Ukuphakamisa inqubo yokukhetha ensimbi kudinga ukulinganiswa okunembile kokuminyana kwe-asidi ku-inthanethi ukuze kuthuthukiswe ikhwalithi, kuncishiswe imfucuza, kanye nezindleko eziphansi. Imitha ye-acid esemgqeni we-Lonnmeter iletha ukunemba okungenakuqhathaniswa, ukuqina, kanye nokuzishintshanisa. Thatha isinyathelo manje—funa isampula eyodwa kwamasampula angu-1,000 (ofike kuqala, anikezwe kuqala) noma landa amahhalainqubo yokukhetha i-asidi pdfukuvula imininingwane. Thumela umbuzo wakho ukuze uthole izixazululo zangokwezifiso ze-OEM/ODM (isb, uxhumano lwe-WiFi, uhlelo lokusebenza lweselula) noma joyina uhlelo lwethu lwe-R&D ukuze uthole ukufinyelela kobuchwepheshe kusenesikhathi. Guqula inqubo yakho ye-pickling metal namuhla!
