Abahlanzi be-CLEANING ALUMINIUM

Ama-alkaline Acashile

Izihlanzi ezine-alkali ze-aluminium zihlukile kulezo ezisetshenziselwa insimbi; ngokuvamile banenhlanganisela yosawoti we-alkaline omnene ukuze bagweme ukuhlasela indawo ye-aluminium. Kwezinye izimo, inani elincane noma elimaphakathi le-caustic soda yamahhala lingase libe khona endaweni yokuhlanza ukususa inhlabathi enzima, noma ukunikeza i-etch oyifunayo.

Endleleni yokufaka isifutho samandla, izingxenye ezizohlanzwa zimiswa emhubheni ngenkathi isisombululo sokuhlanza sikhishwa ethangini lokubamba futhi sifuthwe, ngaphansi kwengcindezi, ezingxenyeni. Isixazululo sokuhlanza siphindaphindwa ngokuqhubekayo. Umfutho we-spray usukela ku-4 kuye ku-40 psi.

Endleleni yokucwiliswa kwesicelo, izingxenye ezizohlanzwa zivele zicwiliswe esixazululweni sokuhlanza esiqukethwe ethangini lensimbi elithambile noma lensimbi engagqwali. I-Electrocleaning inguqulo ekhethekile yokuhlanza ukucwiliswa lapho umbane oqondile udlula isisombululo. Izingxenye ezizohlanzwa ngokuvamile ziyi-anode, kanti amanye ama-electrode alenga ethangini asebenza njenge-cathode. I-Electrocleaning iphumelela kakhulu ekuhlanzeni kunokucwiliswa obala ngenxa yesenzo sokukhuhla samabhamuza omoya-mpilo aphuma phezu kwengxenye. I-oksijeni iphuma ku-electrolysis yamanzi.

Indlela yokusebenzisa yokwesula ngesandla ithola inzuzo eyengeziwe esenzweni esingokomzimba sokususa inhlabathi endaweni engaphezulu ngendwangu noma isipontshi, lapho umhlanzi esiza ukunyibilikisa inhlabathi.

Izihlanzi ezine-alkali zivame ukusetshenziswa ku-aluminium ngokusebenzisa ubuncane bezigaba ezimbili: isiteji sokuhlanza kanye nokugeza ngamanzi. Izigaba ezengeziwe, ukuhlanza nokuwasha, kungasetshenziswa uma kudingeka. Amabhavu amakhemikhali agcinwa kumazinga okushisa asuka ku-80 kuya ku-200°F (27 kuya ku-93″C), ngokuvamile angu-100 kuya ku-140°F (38 kuya ku-60°C) ukuze afuthwe kanye no-140 kuya ku-180°F (60 kuya ku-82°C. ) ukucwiliswa. Izingxenye zivezwe kumakhemikhali imizuzwana engu-30 kuya kumaminithi angu-5+; ngokuvamile imizuzu engu-1 ukuya kwemi-2 yokufutha, kanye nemizuzu emi-2 ukuya kwemi-5 yokucwiliswa. I-concentration yokugeza ye-1/4 kuya ku-16 odgal (2 kuya ku-120 g/L) isetshenziswa; ngokuvamile 1/2 kuya ku-1 odgal(4 kuya ku-8 g/L) yesifutho kanye no-6 kuya ku-12 odgal(45 kuya ku-90 g/L) yokucwiliswa.

Uma kuqhathaniswa nezindleko zokusebenzisa izinhlobo ezihlukahlukene zezihlanzi zamakhemikhali, okubiza kakhulu kungaba umshini wokuhlanza ugesi wokucwilisa ngenxa yokugxila okuphezulu okusetshenziswayo kanye nezindleko zikagesi kumshini wokuhlanza ugesi.

Okungabizi kakhulu kuzoba okokuhlanza isifutho, ukusula ngesandla kuzoba ndawana thize. Uhlobo lwe-alkaline, kuze kube manje, lusebenza kahle kakhulu ezinhlotsheni ezihlanzekile futhi ngokuvamile lubiza kancane ukulusebenza. Ukuze kuncishiswe ukusebenza, izindlela zokusebenzisa zizokhiqizaralIkalwe njengokuthi: ukuhlanza i-electro, ukuhlanza isifutho, ukuhlanza ukucwilisa, nokwesula ngesandla.

Izihlanzi ze-Acid

Izihlanzi ze-Acid ze-aluminium zenziwe ngosawoti omuncu omuncu noma isisekelo se-phosphoric acid. Kunoma yikuphi, noma iyiphi ifilimu ye-oxide ku-aluminium izosuswa yi-acidic medium. Izihlanzi ze-asidi ngokuvamile azisebenzi kahle ekuhlanzeni inhlabathi evamile njengabahlanzi be-alkaline.

Endleleni yokufaka isifutho samandla, izingxenye ezizohlanzwa zimiswa emhubheni ngenkathi isisombululo sokuhlanza sikhishwa ethangini lokubamba futhi sifuthwe, ngaphansi kwengcindezi, ezingxenyeni. Isixazululo sokuhlanza siphindaphindwa ngokuqhubekayo.

Lapho indlela yokucwiliswa yokusetshenziswa isetshenziswa, izingxenye ezizohlanzwa zimane zicwiliswe esixazululweni sokuhlanza esiqukethwe ethangini lensimbi elithambile noma lensimbi engagqwali. Ukwesula ngesandla kuthola inzuzo eyengeziwe osizweni oluphathekayo lokususa inhlabathi phezulu ngendwangu noma isipontshi, lapho umhlanzi esiza ekunyibilikiseni inhlabathi.

Izihlanzi ze-Acid zivame ukusetshenziswa ku-aluminium kusetshenziswa ubuncane bezigaba ezimbili, isiteji sokuhlanza kanye nokugeza ngamanzi. Izigaba ezengeziwe, ukuhlanza nokuwasha, kungasetshenziswa uma kudingeka. Izixazululo ze-asidi zigcinwe ekushiseni kwama-80 kuya ku-200 ° F (27 kuya ku-93 ° C); ngokujwayelekile i-100 kuya ku-140°F (38 kuya ku-60°C) yokufutha kanye no-140 kuya ku-180°F (60 kuya ku-82°C) yokucwiliswa. Izingxenye zivezwa imizuzwana engu-30 kuya kumaminithi angu-5+; ngokuvamile imizuzu engu-1 ukuya kwemi-2 yokufutha kanye nemizuzu emi-2 ukuya kwemi-5 yokucwiliswa. Izixazululo zibanjwe ekuhlanganiseni kwe-1/4 kuya ku-16 odgal (2 kuya ku-120 g/L) ukuze kufuthwe kanye no-6 kuya ku-12 odgal (45 kuya ku-90). g/L) lokucwiliswa.

Uma kuqhathaniswa nezindleko zokusebenzisa izihlanzi ezihlukahlukene, okubiza kakhulu kungaba ukucwiliswa emanzini ngenxa yokugxila okuphezulu okusetshenzisiwe. Okungabizi kakhulu kuzoba izihlanzi zesifutho, ezisula ngesandla endaweni ethile phakathi. Ukuze kuncishiswe ukusebenza, izindlela zokusebenzisa zizokhiqizaralIkalwe ngokuthi: ukuhlanza isifutho, ukucwiliswa emanzini, ukusula izandla.

Neutral Abahlanza

I-neutral isihlanzi se-aluminium singakhiwa ama-surfactants kuphela, i-neutral usawoti kanye nama-surfactants, noma ama-surfactants anezinye izithasiselo eziphilayo. Isixazululo se-neutral ohlanzekile ngokuvamile uzobhalisa phakathi kuka-6 no-8 esikalini se-pH.

Ekusetshenzisweni kwesifutho samandla, izingxenye ezizohlanzwa zilengiswa emhubheni ngenkathi isixazululo sokuhlanza siphonswa ethangini lokubamba futhi sifafazwe ngaphansi kwengcindezi ezingxenyeni. Isixazululo sokuhlanza siphindaphindwa ngokuqhubekayo.

Umfutho we-spray usukela ku-4 kuye ku-40 psi. Indlela yokusebenzisa yokwesula ngesandla ithola inzuzo eyengeziwe esenzweni somzimba sokususa inhlabathi phezu kwendwangu noma isipontshi ngesihlanzi esisiza ukunyibilikisa inhlabathi.

Neutral okuhlanza ngokuvamile asetshenziswa ku-aluminium kusetshenziswa ubuncane bezigaba ezimbili: isiteji sokuhlanza kanye nokugeza ngamanzi. Izigaba ezengeziwe, ukuhlanza nokuwasha, kungasetshenziswa uma kudingeka. Neutral zokuhlanza zigcinwe ebangeni lokushisa elingu-80 kuya ku-200°F (27 kuya ku-93°C); ngokujwayelekile i-120 kuya ku-160°F (49 kuya ku-71°C) yokufutha kanye no-150 kuya ku-180°F (66 kuya ku-82°C) yokucwiliswa. Izingxenye zivezwe kubahlanzi imizuzwana engu-30 ukuze 5+ imizuzu; ngokuvamile imizuzu engu-1 ukuya kwemi-2 yokufutha kanye nemizuzu emi-2 ukuya kwemi-5 yokucwiliswa. Ukuhlushwa kwamakhemikhali kuphakathi kuka-1/4 kuya ku-16 odgal (2 kuya ku-120 g/L) ngokuvamile l kuya ku-2 odgal (8 kuya ku-15 g/L) wokufuthwa kanye no-8 kuya ku-14 od gal (60 kuya ku-105 g/L) lokucwiliswa.

Neutral izinto zokuhlanza azisebenzi njengesicoci sokuqala. Cishe zisetshenziswa njenge-precleaner.
