Ucwaningo nokusebenzisa ubuchwepheshe bokwelashwa kwe-bolt surface

Njengesibophelelo esibalulekile emishinini engumshini, ukusebenza kweamabhawodikuthinta ngqo ukuphepha nokuzinza kwemishini.Ukwelashwa okungaphezulu kuyindlela ebalulekile yokuthuthukisa ukusebenza kwebhawodi nokwelula impilo yesevisi.Kuleli phepha, izinhlobonhlobo zamanje zokwelashwa kwe-bolt surface technologies, okuhlanganisa i-galvanizing, i-electroplating, isifutho, ukwelashwa kokushisa, njll. kubuyekezwa, isimiso, izici, izimo zohlelo lokusebenza kanye nemikhawulo yendlela ngayinye yokwelashwa kuyahlaziywa, futhi ukuthuthukiswa kokuthuthukiswa kobuchwepheshe bokwelashwa kwe-bolt surface esikhathini esizayo kuxoxwa ngakho.

Njenge-fastener esetshenziswa kabanzi emishinini yemishini, ikhwalithi, ukuqina kanye namandla okuthwala ama-bolt kubaluleke kakhulu ekuphepheni kokusebenza kwemishini. Kodwa-ke, ama-bolts avame ukubhekana ne-oxidation, ukugqwala, ukugqwala nezinye izinkinga ngesikhathi sokusetshenziswa, okungeke kunciphise kuphela ukusebenza kwama-bolts, kodwa futhi kungase kuthinte kabi ukuzinza kwalo lonke uhlelo lwemishini. Ngakho-ke, ukwelashwa okungaphezulu kwama-bolt kubaluleke kakhulu. Leli phepha lihlose ukuxoxa ngesimo se-quo, izici kanye nokusetshenziswa kobuchwepheshe bokwelashwa kwe-bolt surface, futhi linikeze ireferensi yocwaningo nokusebenzisa emikhakheni ehlobene.

Isifinyezo sobuchwepheshe bokwelashwa kwe-bolt surface

1. Ukwelashwa ngamagalani

I-galvanizing iyindlela evamile yokwelashwa kwe-bolt surface, ngokumboza ubuso be-bolt nge-layer ye-zinc, ukwakha isendlalelo sokuzivikela, ukuvimbela ngokuphumelelayo ubuso be-bolt oxidation kanye nokugqwala. Ukwelapha okugalela amanzi kuhlukaniswe ngokufaka amadiphu ashisayo okuphehla amanzi kanye nokufaka ugesi kagesi. Idiphu elishisayo elishisayo licwilisa amabhawodi esixazululweni se-zinc esincibilikisiwe ukuze kwakheke ungqimba oluqinile lwezinki, olulungele indawo yangaphandle nezinhlelo zokusebenza ezidinga ukuqina okuphezulu; I-Electrogalvanizing isebenzisa umgomo we-electrolysis ukuze ifake ungqimba oluncane lwezinc phezu kwebhawodi, elifanele indawo yasendlini kanye nezikhathi ezinezidingo eziphansi zempilo yesevisi. I-galvanizing akugcini nje ukuthuthukisa ukumelana nokugqwala kwama-bolts, kodwa futhi kwandisa ubuhle bawo. Kodwa-ke, ukugqoka kungase kukhiqize i-hydrogen embrittlement ngaphansi kwezimo ezithile, ezithinta amandla nokuphepha kwebhawodi. Ukwengeza, inqubo yamagalani ingase ikhiqize amanzi angcolile, igesi engcolile nezinye izinto ezingcolile, okudingeka ziphathwe kahle ukuze zihlangabezane nezidingo zokuvikela imvelo.

2. I-Electroplating

I-Electroplating ingenye yezindlela ezisetshenziswa kakhulu ekwelashweni kwe-bolt surface. Ngokufaka ungqimba lwensimbi phezu kwebhawodi, njenge-chromium, i-nickel, njll., ukumelana nokugqwala, ukuqina kanye nobuhle bebhawodi kungathuthukiswa. Amabhawodi aphathwe nge-chromium plating azinzile kakhulu emkhathini, akulula ukuthi ashintshe umbala futhi alahlekelwe ukucwebezela, futhi anokuqina okuphezulu nokumelana nokugqokwa okuhle. I-Chromium plating ivamise ukusetshenziselwa ukuhlobisa futhi kuthuthukiswe ukumelana nokugqwala kwamabhawodi, kodwa ayivamisile ukusetshenziswa ezindaweni zezimboni lapho ukumelana nokugqwala kuphezulu kakhulu. Ukwelashwa kwe-nickel plating kungathuthukisa ukumelana nokugqwala kwama-bolts futhi kuthuthukise ubuhle bawo.I-nickel coating ine-ductility enhle nokuqina, okulungele izikhathi ezinezidingo eziphezulu endaweni ye-bolt.

3. Futha ukwelashwa

Ukwelashwa ngokufutha kuyinqubo lapho upende ufafazwa ngokulinganayo phezu kweibhawodiphezulu ngesibhamu se-spray.Ukufafaza akukwazi nje ukuhlobisa ukubukeka kwebhawodi, kodwa futhi kuthuthukise ukumelana kwayo nokugqwala.Izindlela ezijwayelekile zokufafaza i-sandblasting, i-spray painting, i-spray polyimide nokunye.Phakathi kwazo, ukwelashwa kwe-spray yokudweba kusetshenziswa kakhulu emikhiqizweni ye-elekthronikhi nakwezinye izimboni ngenxa yombala wayo ocebile nokwakhiwa okulula.Izinzuzo zokufafaza ukwelashwa ziwukwakhiwa okulula, izindleko eziphansi, futhi ungakhetha imibala ehlukene kanye nezinto zokwakha ngokuvumelana nezidingo zakho.Kodwa-ke, ukunamathela nokuqina kwezigqoko zesifutho kungase kungabi kuhle njengokwelashwa kwe-electroplating ne-galvanizing.

4. Ukwelashwa kokushisa

Ukwelashwa kokushisa kuyindlela ngokushintsha ubulukhuni namandla e-bolt surface.Ngokushisa, ukufakwa kwe-insulation kanye nezinqubo zokupholisa, ukwakheka kwebhawodi kungathuthukiswa, futhi ukumelana kwayo nokugqoka namandla okuqinile kungathuthukiswa.Ukwelashwa kokushisa kulungele ngokukhethekile ukuthwala imithwalo emikhulu yemishini noma izinguquko ezishisayo kakhulu, njenge-aerospace, ezempi kanye nezinye izinkambu.Kodwa-ke, inqubo yokwelapha ukushisa ingaholela ekushintsheni kosayizi we-bolt, okudinga ukulawulwa okuqinile kwemingcele yenqubo ukuze kuqinisekiswe ikhwalithi.

5. Amanye amasu okucubungula

Ngaphezu kobuchwepheshe obujwayelekile bokwelapha obuphezulu obungenhla, kunenani lobunye ubuchwepheshe obusetshenziswa kabanzi emkhakheni wokwelashwa kwe-bolt surface.Isibonelo, inqubo ye-phosphating yenziwa ngokucwilisa ama-bolts kwisisombululo esiphezulu sokushisa esiqukethe i-phosphoric acid ne-dihydrogen phosphate ukuze kwakhiwe ifilimu ye-crystalline phosphating eyakhiwe ngama-phosphate precipitates.Ifilimu ye-Phosphating inezindawo ezinhle zokunqanda ukugqwala, kodwa idinga ukusetshenziswa ngamafutha e-anti-rust ukuze inwebe ngokuphumelelayo impilo yesevisi yama-bolts.Ukwengeza, ubuchwepheshe obusha bokwelashwa kwendawo efana nokwelashwa kwe-zincizing kanye nokwelashwa kwe-dacromet buye bathola ukunakwa kanye nokusetshenziswa.

Isimo sohlelo lokusebenza nokuhlaziywa komkhawulo

Ukukhethwa kobuchwepheshe bokwelashwa kwe-bolt surface kuncike endaweni ethile yokusetshenziswa kanye nezidingo zokusebenza. Ngokwesibonelo, kwezobunjiniyela basolwandle, amabhawodi adinga ukuchayeka kaningi emanzini olwandle, futhi usawoti kanye nomswakama kunomthelela omkhulu ekugqwaleni kwamabhawodi. Ukwelashwa okungaphezulu kwamabhawodi anjalo kuvame ukukhethwa nge-galvanized ephezulu noma i-titanium alloy coating ukuze kuhlinzekwe isivikelo esinamandla sokulwa nokugqwala. Emishinini yokushisa ephezulu yezimboni, izidingo zokwelashwa kwe-bolt surface zinaka kakhulu ukumelana nokushisa okuphezulu kanye nokumelana nokukhathala okushisayo, nokwelashwa kokushisa noma ubuchwepheshe bokugqoka i-titanium busetshenziselwa ukuthuthukisa ukumelana nokushisa kwamabholithi.

Kodwa-ke, inqubo ngayinye yokwelashwa kwendawo inemikhawulo yayo.Isibonelo, nakuba ukwelashwa kwama-galvanized kuyindleko ephansi nokusebenza okuhle kokulwa nokugqwala, kungase kukhiqize into ye-hydrogen embrittlement kanye nezinkinga zokuvikela imvelo;Nakuba ukwelashwa kwe-electroplating kungathuthukisa ubulukhuni nobuhle bamabhawudi, izindleko ziphezulu futhi ukunamathela kungase kwehla ngaphansi kwezimo ezithile. Ukufafaza ukwelashwa kulula ukwakha, kodwa ukunamathela nokuqina kungase kungenele. Ngakho-ke, ekusetshenzisweni okusebenzayo, kuyadingeka ukukhetha ubuchwepheshe obufanele bokwelashwa kwendawo ngokusho kwesimo esithile ngokucabangela izici ezihlukahlukene.

Umkhuba wentuthuko yesikhathi esizayo

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe,ibhawodiubuchwepheshe bokwelapha okungaphezulu bubuye buhlale bushintsha futhi buthuthukiswa.Esikhathini esizayo, singabona kusengaphambili ukuthi ukuvela okuqhubekayo kwezinto ezintsha nezinqubo ezintsha kuzokhuthaza ukuthuthukiswa kobuchwepheshe bokwelashwa kwe-bolt surface.Isibonelo, ngokumboza ubuso bebhawodi nge-nanoscale coating, ubuchwepheshe be-nanocoating abukwazi nje ukuthuthukisa ukumelana nokugqwala, kodwa futhi buthuthukise amandla ayo e-antibacterial kanye ne-antioxidant.Ukwengeza, ubuchwepheshe bokwelashwa kwendawo ezungezile buzoba ngenye yezindlela zokuthuthuka zesikhathi esizayo ukuze kuhlangatshezwane nezidingo eziqinile zemvelo.

isiphetho

Ubuchwepheshe bokwelashwa kwe-Bolt surface budlala indima ebalulekile ekuthuthukiseni ukusebenza kwebhawudi nokwandisa impilo yesevisi. Kuleli phepha, amasu ahlukahlukene okwelashwa okungaphezulu kwamabholidi abuyekezwa, kufaka phakathi i-galvanizing, i-electroplating, isifutho, ukwelashwa kokushisa, njll., futhi isimiso, izici, izimo zohlelo lokusebenza kanye nemikhawulo yendlela yokwelapha ngayinye ihlaziywa. Esikhathini esizayo, ngokuvela okuqhubekayo kwezinto ezintsha kanye nezinqubo ezintsha kanye nokuthuthukiswa kwezidingo zokuvikelwa kwemvelo, ubuchwepheshe bokwelashwa kwe-bolt surface buzothuthuka ngendlela esebenza kahle, ukuvikelwa kwemvelo nokuhlala njalo.
