Ukuhlanza okusebenzayo emazingeni okushisa aphansi, ngisho ne-ambient, kuyenzeka futhi kudala indawo yokusebenza ephephile futhi kunciphisa isidingo samandla.
UMB: Sesineminyaka eminingi sisebenzisa umkhiqizo ofanayo wokususa amafutha futhi usebenza kahle kakhulu kithi, kodwa unokugeza okufushane futhi usebenza cishe ku-150oF.Cishe ngemva kwenyanga, izingxenye zethu azisahlanzwa ngokuphumelelayo.Yiziphi ezinye izindlela ezikhona?
IMP: Ukuhlanza kahle indawo engaphansi kwe-substrate kubalulekile ekuzuzeni ingxenye ependiwe yekhwalithi ephezulu.Ngaphandle kokukhipha inhlabathi (kungakhathaliseki ukuthi i-organic noma i-inorganic), kunzima kakhulu noma akunakwenzeka ukwakha ukugqoka okufiselekayo phezulu.Inguquko yemboni isuka ezimbotsheni zokuguqulwa kwe-phosphate iye kweyenziwe ifilimu emincane eqinile (njenge-zirconium nama-silanes) ikhulise ukubaluleka kokuhlanzwa kwe-substrate okungaguquki.Ukushiyeka kwekhwalithi yokwelapha kusengaphambili kunomthelela ekulimaleni kukapende obizayo futhi kuwumthwalo ekusebenzeni kahle.
Izihlanzi ezivamile, ezifana nezakho, ngokuvamile zisebenza emazingeni okushisa aphezulu futhi zivame ukuba nomthamo ophansi wokulayisha uwoyela.Lezi zihlanzi zinikeza ukusebenza okwanele uma kusha, kodwa ukusebenza kokuhlanza kuvame ukuncipha ngokushesha, okuholela ekuphileni okufushane okugeza, ukukhubazeka okukhulayo kanye nezindleko zokusebenza eziphezulu.Ngempilo yokugeza emfushane, imvamisa yezimonyo ezintsha iyakhula, okuholela ezindlekweni ezinkulu zokulahlwa kwemfucuza noma zokuhlanza amanzi angcolile.Ukuze kugcinwe isistimu kumazinga okushisa aphezulu okusebenza, inani lamandla adingekayo likhulu kakhulu kunenqubo yezinga lokushisa eliphansi.Ukubhekana nezinkinga zamandla aphansi kawoyela, kungase kusetshenziswe izinto ezisizayo, okuholela ezindlekweni ezengeziwe nokugcinwa kwazo zisesimweni esihle.
Abahlanzi besizukulwane esisha bayakwazi ukuxazulula ukushiyeka okuningi okuhambisana nabahlanzi abajwayelekile.Ukuthuthukiswa kanye nokusetshenziswa kwamaphakheji e-surfactant ayinkimbinkimbi kunikeza izinzuzo eziningi kubafaki bezicelo - ikakhulukazi ngokuphila okunwetshiwe kokugeza.Izinzuzo ezengeziwe zihlanganisa ukukhiqiza okukhuphukile, ukugezwa kwamanzi angcolile nokonga amakhemikhali, kanye nokuthuthukiswa kwengxenye yekhwalithi ngokugcina ukusebenza okuzinzile isikhathi eside.Ukuhlanza okuphumelelayo emazingeni okushisa aphansi, ngisho namazinga okushisa azungezile, kungenzeka.Lokhu kudala indawo yokusebenza ephephile futhi kunciphisa izidingo zamandla, okuholela ekuthuthukisweni kwezindleko zokusebenza.
UMB: Ezinye zezingxenye zethu zinamashisela kanye nokusikeka kwe-laser okuvamise ukuba yimbangela yokulimala okuningi noma ukusebenza kabusha.Njengamanje, asizinaki lezi zindawo ngoba kunzima ukususa isikali esakhiwe ngesikhathi se-welding kanye ne-laser cutting.Ukunikeza amakhasimende ethu isixazululo esisebenza kahle kuzosivumela ukuthi sandise ibhizinisi lethu.Singakufeza kanjani lokhu?
A: Izikali ze-Inorganic, njengama-oxides akhiwe ngesikhathi sokushisela nokusikwa kwe-laser, avimbela yonke inqubo yokwelapha kusengaphambili ukuthi isebenze kahle.Ukuhlanza inhlabathi ye-organic eduze kwama-welds kanye nokusikeka kwe-laser kuvame ukumpofu, futhi ukwakheka kwe-conversion coating akwenzeki esikalini se-inorganic.Ngopende, izikali ze-inorganic zibangela izinkinga eziningana.Ukuba khona kwesikali kuvimbela upende ukuthi unganamatheli kusisekelo sensimbi (okufana nezingubo zokuguqulwa), okuholela ekugqwaleni ngaphambi kwesikhathi.Ukwengeza, i-silica inclusions eyakhiwe ngesikhathi senqubo yokushisela ivimbela ukumbozwa okugcwele ekufakweni kwe-ecoat, ngaleyo ndlela kwandise amathuba okugqwala ngaphambi kwesikhathi.Abanye abafake izicelo bazama ukuxazulula lokhu ngokufaka upende owengeziwe ezingxenyeni, kodwa lokhu kwandisa izindleko futhi akuthuthukisi njalo ukumelana nomthelela kapende ezindaweni ezinesikali.
Abanye abafake izicelo basebenzisa izindlela zokususa isikali se-weld nese-laser, njengama pickles e-asidi nezindlela eziwumshini (ukuqhuma kwemidiya, ukugaya), kodwa kukhona ukonakala okuphawulekayo okuhlotshaniswa nalokho ngakunye.Amakhukhamba e-Acid abeka engcupheni yokuphepha kubasebenzi, uma engasebenzi kahle noma ngezinyathelo ezifanele kanye nemishini yokuzivikela.Baphinde babe nempilo emfushane yokugeza njengoba izikali zakha esixazululweni, okumele zilahlwe noma zihanjiswe ngaphandle kwendawo ukuze zilahlwe.Lapho kucutshungulwa ukuqhunyiswa kwemidiya, ukususwa kwesikali se-weld ne-laser kungase kusebenze kwezinye izinhlelo zokusebenza.Kodwa-ke, kungaholela ekulimaleni kwendawo engaphansi, inhlabathi ikhule uma imidiya engcolile isetshenziswa futhi inezinkinga zomugqa wokubona wezingxenye eziyinkimbinkimbi zejometri.Ukugaya mathupha nakho kulimaza futhi kushintsha indawo engaphansi, ayilungele izingxenye ezincane futhi kuyingozi enkulu kubaqhubi.
Ukuthuthukiswa kobuchwepheshe bokwehlisa amakhemikhali kunyukile eminyakeni yamuva, njengoba abafake izicelo bebona indlela ephephile nengabizi kakhulu yokuthuthukisa ukukhishwa kwe-oxide ingaphakathi kokulandelana kokwelashwa kusengaphambili.Amakhemikhali esimanjemanje ehlisa izinga anikeza inqubo eguquguqukayo enkulu kakhulu (esebenza kukho kokubili ukucwiliswa kanye nezicelo zokufutha);azinazo izinto eziningi eziyingozi noma ezilawulwayo, njenge-phosphoric acid, i-fluoride, i-nonylphenol ethoxylates nama-hard chelating agents;futhi ingase ibe namaphakheji e-surfactant eyakhelwe ngaphakathi ukuze isekele ukuhlanzwa okuthuthukisiwe.Intuthuko ephawulekayo ihlanganisa ama-pH angathathi hlangothi okwehlisa izinga lokuphepha kwabasebenzi kanye nokunciphisa ukulimala kwemishini kusukela ekuchayekeni kuma-acids abolayo.
