Xa usiva 'iintsimbi zomzila wesikhokelo somzila wentsimbi', abantu abaninzi bacinga ngoko nangoko ngokumelana nomhlwa. Ayonto iphosakeleyo, kodwa yindawo yokuqala ebonisa imiceli mngeni yokwenyani. I-zinc yokugquma yinwebu nje enye yebali; olona vavanyo lokwenyani yindlela lo mzila kaloliwe osebenza ngayo phantsi komthwalo oqhubekayo, ubushushu, kunye nokuqhawuka iminyaka ekupheleni. Ndibone iiprojekthi ezininzi kakhulu apho i-spec sheet ijongeka igqibelele, kodwa ukufakela kunye nokusebenza kwexesha elide kuxelele intsomi eyahlukileyo.
Umbono ongeyiyo ongundoqo: Nguloliwe nje ogqunyiweyo
Owona mgibe mkhulu kukuphatha ezi ziporo zesikhokelo njengempahla yorhwebo. Awunako uku-odola iileyili zesikhokelo eziphekiweyo kwaye ulindele ukuba zifake ngaphandle komthungo kumgca wokukha ngesantya esiphezulu okanye umgca wokugalela. Umgangatho wentsimbi ye-substrate ubaluleke kakhulu. Umzila kaloliwe owenziwe ngentsimbi eqhelekileyo ethambileyo, nokuba unomaleko oshinyeneyo oshushu-dip owenziwe ngamazinki, uya kunxiba kwaye uguge ngokukhawuleza phantsi kwemikhosi esecaleni yekhareji ehambayo kunomnye owenziwe kwi-alloy yodidi oluphezulu, ene-tensile ephezulu. Inkqubo yokugaya ngokwayo inokubangela uxinzelelo ukuba isiseko sesinyithi asilungiswanga okanye sikhethwe ngokuchanekileyo.
Ndikhumbula iprojekthi yokubuyisela umgca we-galvanizing oqhubekayo apho umxhasi ugxininise ekusebenziseni intsimbi yesakhiwo esiqhelekileyo kwimigaqo emitsha yesikhokelo, ukubeka phambili iindleko zokuqala. Kwisithuba seenyanga ezisibhozo, siye sabona iipateni zokunxiba eziqaphelekayo hayi kwi-coating, kodwa i-deformation encinci kwiprofayili kaloliwe ngokwayo. I-zinc yayingatshintshi, kodwa umzila kaloliwe wawusilela ngobuchule. Ukulungiswa kwakubiza kakhulu-ixesha lokuphumla, ukulungiswa kwakhona, kwaye ekugqibeleni kufakwe iileyili ezenziwe ngentsimbi efanelekileyo, eqinile ngaphambi kokugalela. Sifunda ntoni? Ingubo ikhusela umhlwa; ayibuyiseli iipropati zoomatshini ezihlwempuzekileyo.
Apha kulapho ubuchwephesha besiseko ekudala bekho kunye neqabane lobuchwephesha bubaluleke kakhulu. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye neminyaka yabo engama-30 ekubumbeni nasekwenzeni, bayakuqonda oku kusebenzisana. Babengayi kubona nje isiporo; baya kuqwalasela yonke imeko-bume yenkonzo-ibhayisekile ye-thermal ukusuka kubushushu benkqubo, ukuvezwa kweekhemikhali ukusuka kwimimandla yonyango lwangaphambili, kunye nemithwalo yempembelelo-phambi kokucebisa imathiriyeli ye-substrate, nokuba yinqanaba elithile lentsimbi okanye i-alloy edibeneyo.
Ukuchaneka akuxoxiswana, kwanasemva kokugalelwa
Olunye uqwalaselo oluxhaphakileyo kukucinga ukuba inkqubo yokugalela amanzi ayisayi kuchaphazela unyamezelo olubalulekileyo lukaloliwe. I-Hot-dip galvanizing ibandakanya ukuntywiliselwa kwi-zinc etyhidiweyo malunga ne-450°C. Oku kunokubangela ukuphazamiseka kwe-thermal, kwaye i-coating yongeza ubukhulu-ngokuqhelekileyo phakathi kwe-70 ukuya kwi-150 microns. Ukuba umzila kaloliwe awutshintshwanga ukuya kunyamezelo olugqithisekileyo lwangaphambili lokugalela okubangela obu bunzima bokugquma, imilinganiselo yakho yokugqibela iya kucinywa.
Oku sakufunda kabuhlungu kumgca wokudityaniswa kwezixhobo zemoto. I iileyili zesikhokelo somgca wentsimbi yokuvelisa bekufanele ukuba babe nokunyamezela ukuvuleka kwe-0.1mm ngemitha nganye. Zazichanekile-zisemhlabeni kakuhle phambi kokuba zithunyelwe ngenqanawa ukuze zifakwe igalvanizing. Xa bebuya, isambatho sasingenasiphako, kodwa ukucaca kwakuphume malunga ne-0.5mm kumacandelo ngenxa yokupholisa okungalinganiyo kunye nokukhululeka koxinzelelo. Ibhetshi yonke kwafuneka iphinde ilungelelaniswe kusetyenziswa ii-hydraulic presses ngendlela elawulwayo, umsebenzi obuthathaka wokuphepha ukukrazula i-zinc layer.
Apha kulapho isakhono sokuvelisa esidibeneyo sisithixo. Umthengisi ophethe zombini i-CNC machining kwaye unamava anzulu kunye nokuziphatha okubonakalayo, njenge-QSY, unokulawula oku ngokupheleleyo. Bangakwazi umatshini icandelo, bahlala bejonga okanye bacebise kwiiparameters zenkqubo ye-galvanizing kwi-castings yabo ethile, kwaye emva koko benze ukuqinisekiswa kwe-post-galvanizing kunye nokulungiswa komatshini xa kuyimfuneko. Le loop yolawulo yinto ongayifumaniyo kumthengisi okanye umenzi olula.
UMtyholi kwiiNkcukacha: Ukunyuka kunye nokulungelelaniswa
Kwanomzila kaloliwe ogqwesileyo awunamsebenzi ukuba ufakwe kakubi. Indawo yokunyuka-ngokuqhelekileyo isakhelo sensimbi yesakhiwo somgca wokuvelisa-kufuneka silungiswe. Silwe amadabi ngokukhazimla kunye nokusila kwisiza kuba imiqadi exhasayo ibingabekwanga kakuhle phambi kofakelo lukaloliwe. Umphezulu wegalvanized nawo ufuna ukuphathwa ngokucophelela; i-welding kuyo okanye kufuphi nayo ngaphandle kweenkqubo ezifanelekileyo kuya kutshabalalisa i-zinc coating kwindawo echatshazelwe ngubushushu, idale i-corrosion hotspot yexesha elizayo.
Ingcebiso esebenzayo kukuchaza imingxunya exhonywe ngoomatshini okanye iindawo zokubeka kumzila kaloliwe, kunye nokusebenzisa iipadi zokubeka zodwa okanye iishim ezigqunywe ngokukodwa ukunqanda ukonakala kwegalvanic phakathi komgaqo kaloliwe kunye nesakhelo sentsimbi yekhabhoni. Musa nje ukuwelda isibiyeli ngqo kwindawo ebalekayo kaloliwe. Ndiyibonile yenziwe, kwaye kukulungiswa okusisigxina okulindileyo ukuba kwenzeke. Iqela kwi tsngtaocnc.com ihlala ibonelela ngemizobo exhomisayo eneenkcukacha kunye neengcebiso zokuhambelana kwezinto ngenxa yesi sizathu, esithathwe kumava abo omatshini kunye namava endibano.
Ulungelelwaniso lelinye irhamncwa. Ukusebenzisa inqanaba lomoya wesintu akwanelanga kwimigca emide kuneemitha ezimbalwa. Udinga izixhobo zokulungelelanisa okanye ze-laser. Injongo ayililo nje inqanaba, kodwa ukuphumeza iprofayile engaguqukiyo, egudileyo ebalekayo kubo bonke ubude, obunokuthi bubandakanye ngabom i-camber encinci okanye imbuyekezo yokuphambuka komqadi phantsi komthwalo. Apha kulapho ukuthi tye kwendalo kunye nokungaguquguquki kukaloliwe njengoko uphosa kunye nomatshini kuba sisiseko sempumelelo.
UKhetho LweMathiriyeli Ngaphaya Kwentsimbi Engaxutywanga
Ngelixa sigxile kwintsimbi ekhandisiweyo, kufanelekile ukwahluka okufutshane. Kumacandelo athile omgca wemveliso-njengakwimithombo yobushushu obunzulu okanye kwiindawo ezigqithiselayo ezirhabaxa kakhulu-ngamanye amaxesha isiseko semathiriyeli esahlukileyo sikrelekrele phambi kokuvuthela. Ngokomzekelo, i-alloy iron eqinisiweyo okanye i-substrate ye-stainless-steel (ethi ke ifakwe i-galvanized ukwenzela ukhuseleko olongezelelweyo kwindawo edibeneyo yeekhemikhali) inokubonelela ngeendleko ezingcono zokuphila.
Le yinzuzo yokusebenza neengcali ezinepotifoliyo yezinto ezibanzi. Umsebenzi we-QSY onee-alloys ezikhethekileyo ezifana ne-nickel-based okanye i-cobalt-based alloys yeendawo ezingqongileyo ezigqithiseleyo zazisa indlela yabo kwizinto eziqhelekileyo eziqhelekileyo. Bayayiqonda i-metallurgy. Basenokuthi bacebise, umzekelo, ukusebenzisa i-spheroidal graphite cast iron for some non-critical guide train sections apho i-vibration damping ibaluleke kakhulu kunamandla okugqibela okuqina, kunye nokuyigalela. Luhlobo lwesayensi yezinto ezisetyenziswayo ezisombulula iingxaki kunokuzalisekisa nje umyalelo.
Kuba undoqo iireyile zokukhokela kwicandelo eliphambili le-galvanizing ngokwayo, intsimbi ephakathi kwekhabhoni elungeleleneyo, iphathwe ngokufanelekileyo ubushushu (iqhelekileyo okanye icinywe kwaye inomsindo) ukuzinza komgangatho kunye nokumelana nokunxiba, emva koko i-hot-dip galvanized, idla ngokuba yindawo emnandi. Inika amandla angundoqo okuxhathisa i-deformation kunye nomaleko wedini ukulwa nomoya ongcolisayo.
Umbono wexesha elide: uLondolozo kunye noHlolo
Akukho nto ihlala ngonaphakade, nkqu nesiporo senziwe kakuhle. Undoqo kukuthotywa okunokucingelwa kwangaphambili. Inkqubo kaloliwe elungileyo ivumela ukuhlolwa nokugcinwa. Oku kuthetha ukuyila iindawo zofikelelo zokulinganisa. Sisebenzisa iindlela ezilula kodwa ezisebenzayo: iitshekhi zonyaka zobunzima bokugquma kunye ne-gauge yamagnetic kwiindawo eziqingqiweyo, ukukhangela iipatheni zokugqoka kwindawo esebenzayo, kunye nokujonga nayiphi na i-cracking okanye i-peeling ye-zinc, ngakumbi kwiindawo ze-weld okanye iintambo ezibukhali.
Imowudi yokusilela kunqabile ukuba i-zinc inxibe ngendlela efanayo. Idla ngokuhlala kwindawo- kwindawo edibeneyo, kwindawo yokunyuka, okanye apho inkunkuma ibanjwe kwaye yabangela ukukrazula. Ukuba nobudlelwane nomqambi wakho kuthetha ukuba unokukhangela amacandelo ahambelanayo okutshintsha okanye ukunxiba imicu. Inkampani eneprofayile ye-QSY ayingomthengisi nje; baba nguvimba wobugcisa womgca wakho. Baneepateni zokusa kunye neenkqubo zobuchwephesha, ngoko ke ukufumana indawo ehambelana ngokugqibeleleyo kwiminyaka emihlanu okanye elishumi yinto ecacileyo, ukuphepha ukwenza ubunjineli bomgca obiza imali eninzi.
Ekugqibeleni, ukucacisa iileyili zesikhokelo somgca wentsimbi yokuvelisa kukuzilolonga kwiinkqubo zokucinga. Asinto ithengwe; lutyalo-mali ekuthembekeni kwayo yonke inkqubo yokuhamba yomgca wakho. Ifuna ingqwalasela kwisayensi yezinto, ubunjineli obuchanekileyo, ubugcisa bofakelo, kunye nokucwangcisa ubomi. Ukusika iikona kuzo naziphi na ezi zigaba zikhokelela kwiindleko eziphezulu phantsi komgca ngexesha lokunciphisa, ukulungiswa, kunye nokulahleka kwemveliso. Injongo kukuyifaka kwaye, ngaphandle kokuhlolwa kwesiqhelo, ukulibala malunga nayo ishumi leminyaka okanye ngaphezulu. Olo xolo lwengqondo luvela kubunzulu bokuqonda emva kwecandelo, hayi nje ukugqiba kwalo phezulu.
