Ukucoca okusebenzayo kwindawo ephantsi, nkqu namaqondo obushushu akwi-ambient, kuyenzeka kwaye kudala indawo yokusebenza ekhuselekileyo kwaye kunciphisa iimfuno zamandla.
Umbuzo: Besisoloko sisebenzisa imveliso efanayo yokuthoba igrisi iminyaka emininzi kwaye isebenza kakuhle kuthi, kodwa inobomi obufutshane bokuhlambela kwaye isebenza malunga ne-150oF.Emva kwenyanga, iinxalenye zethu azisacocwa kakuhle.Ziziphi ezinye iindlela ezikhoyo?
A: Ukucoca ngokufanelekileyo umphezulu we-substrate kubalulekile ekuphumezeni indawo epeyintiweyo ekumgangatho ophezulu.Ngaphandle kokususa imihlaba (nokuba i-organic okanye i-inorganic), kunzima kakhulu okanye akunakwenzeka ukwenza isambatho esinqwenelekayo phezu komhlaba.Ukutshintshwa kweshishini ukusuka kwiingubo zokuguqulwa kwe-phosphate ukuya kwiingubo ezizinzileyo zefilimu ezincinci (ezifana ne-zirconium kunye ne-silanes) ziye zandisa ukubaluleka kokucoca i-substrate engaguqukiyo.Iintsilelo kumgangatho wokulungiswa kwangaphambili zinegalelo kwiziphene zepeyinti ezixabisa imali eninzi kwaye zingumthwalo ekusebenzeni kakuhle.
Abacoci besiqhelo, abafana nezakho, basebenza ngokwesiqhelo kumaqondo obushushu aphezulu kwaye badla ngokuba nomthamo osezantsi wokulayisha i-oyile.Ezi zihlambululi zibonelela ngokusebenza okwaneleyo xa zintsha, kodwa ukucoca ukusebenza rhoqo kuncipha ngokukhawuleza, okubangelwa ubomi obufutshane bokuhlamba, ukukhubazeka okwandisiweyo kunye neendleko eziphezulu zokusebenza.Ngobomi obufutshane bokuhlambela, ukuphindaphindwa kwezinto ezintsha zokuzihombisa ziyenyuka, okukhokelela kwinkcitho enkulu yokulahlwa kwenkunkuma okanye iindleko zokucocwa kwamanzi amdaka.Ukugcina inkqubo kubushushu bokusebenza obuphezulu, ubungakanani bamandla afunekayo bukhulu kakhulu kunenkqubo yobushushu obuphantsi.Ukuchasana nemiba yamandla e-oyile ephantsi, izixhobo ezincedisayo zingaphunyezwa, ezikhokelela kwiindleko ezongezelelweyo kunye nokugcinwa.
Abacoci besizukulwana esitsha bayakwazi ukusombulula iintsilelo ezininzi ezinxulumene nabacoci besiqhelo.Uphuhliso kunye nokuphunyezwa kweepakethi ezintsonkothileyo ze-surfactant zibonelela ngeenzuzo ezininzi kubafaki-zicelo - ngakumbi kubomi obude bokuhlambela.Izibonelelo ezongezelelweyo ziquka ukunyuka kwemveliso, ukucocwa kwamanzi amdaka kunye nokugcinwa kweekhemikhali, kunye nokuphuculwa kwenxalenye yomgangatho ngokugcina ukusebenza okuzinzileyo ixesha elide.Ukucoca okusebenzayo kumaqondo aphantsi, kunye namaqondo okushisa aphantsi, kunokwenzeka.Oku kudala indawo yokusebenza ekhuselekileyo kwaye kunciphisa iimfuno zamandla, okukhokelela ekuphuculweni kweendleko zokusebenza.
Umbuzo: Amanye amalungu ethu ane-welds kunye nokusikwa kwe-laser okuhlala kungunobangela weziphene ezininzi okanye ukusebenza kwakhona.Okwangoku, asiyihoyi le mimandla kuba kunzima ukususa isikali esenziwe ngexesha le-welding kunye ne-laser cutting.Ukunika abathengi bethu isisombululo esisebenza kakhulu kunokusivumela ukuba sandise ishishini lethu.Sinokukuphumeza njani oku?
A: Izikali ze-inorganic, ezinje ngeeoksidi ezenziwe ngexesha le-welding kunye ne-laser cut, zithintela yonke inkqubo yonyango lwangaphambili ekusebenzeni ngokufanelekileyo.Ukucoca imihlaba yezinto eziphilayo kufuphi ne-welds kunye nokunqunyulwa kwe-laser kudla ngokungahambi kakuhle, kwaye ukubunjwa kwengubo yokuguqula akwenzeki kwizikali ze-inorganic.Kwiipeyinti, izikali ze-inorganic zibeka imiba emininzi.Ubukho besikali buthintela ipeyinti ekubambeleleni kwisiseko sesinyithi (esifana neengubo zokuguqula), okukhokelela ekudlekeni kwangaphambi kwexesha.Ukongeza, ukubandakanywa kwe-silica okwenziwe ngexesha lenkqubo ye-welding kuthintela ukugubungela ngokupheleleyo kwizicelo ze-ecoat, ngaloo ndlela kwandisa amathuba okubola kwangaphambi kwexesha.Abanye abafakeli bazama ukusombulula oku ngokufaka ipeyinti eninzi kumalungu, kodwa oku kwandisa iindleko kwaye akusoloko kuphucula ukuchasana kwempembelelo yepeyinti kwiindawo ezilinganisiweyo.
Abanye abafaki-zicelo baphumeza iindlela zokususa i-weld kunye ne-laser isikali, njenge-acid pickles kunye neendlela zomatshini (ukuqhunyiswa kweendaba, ukugaya), kodwa kukho ukungonakali okubalulekileyo okuhambelana nenye yezo.I-Acid pickles ibeka ingozi yokhuseleko kubasebenzi, ukuba ayisetyenziswanga ngokufanelekileyo okanye ngokufanelekileyo kunye nezixhobo zokukhusela.Kananjalo banobomi obufutshane bokuhlambela njengoko izikali zikhula kwisisombululo, ekufuneka ke ngoko zicocwe inkunkuma okanye zithunyelwe ngaphandle kwendawo ukuze zilahlwe.Ekuqwalaseleni ukuqhuma kweendaba, ukususwa kwe-weld kunye ne-laser scale kunokusebenza kwezinye izicelo.Nangona kunjalo, kunokubangela umonakalo kumphezulu we-substrate, ukumilisela imihlaba ukuba imidiya engcolileyo isetyenzisiwe kwaye inemiba yomgca wombono wecandelo elinzima lejometri.Ukusila ngesandla kuphinde konakalise kwaye kuguqule umphezulu we-substrate, ayifanelekanga kumalungu amancinci kwaye yingozi enkulu kubaqhubi.
Uphuhliso lobuchwephesha bokuhlanjululwa kweekhemikhali luye lwanda kwiminyaka yamuva nje, njengoko abafaki-zicelo beqaphela eyona ndlela ikhuselekileyo kunye neyona ndlela ingabizi kakhulu yokuphucula ukususwa kwe-oxide ingaphakathi kokulandelelana kwangaphambili.Iikhemistri zale mihla zokuhla zibonelela ngenkqubo eguquguqukayo enkulu (ukusebenza kokuntywiliselwa kunye nokutshiza izicelo);azinazinto ezininzi ezinobungozi okanye ezilawulwayo, ezifana ne-phosphoric acid, i-fluoride, i-nonylphenol ethoxylates kunye ne-hard chelating agents;kwaye inokuba neepakethi ezakhelwe ngaphakathi zokuxhasa ukucoca.Inkqubela phambili ephawulekayo ibandakanya i-pH engathathi hlangothi decalers kukhuseleko oluphuculweyo lwabasebenzi kunye nokunciphisa umonakalo wesixhobo ukusuka ekuvezweni kwiiasidi ezidliwayo.
