Tsvagiridzo uye kushandisa bolt pamusoro pekurapa tekinoroji

Sechinhu chakakosha chekusungira mumichina michina, kuita kwemabhaudhiinobata zvakananga kuchengetedzwa uye kugadzikana kwemidziyo.Kurapa kwepamusoro inzira yakakosha yekuvandudza kuita kwebhoti uye kurebesa hupenyu hwebasa.Mune pepa rino, akasiyana emazuva ano mabhoti epamusoro ekurapa tekinoroji, anosanganisira galvanizing, electroplating, spraying, kupisa kupisa, nezvimwe zvinoongororwa, iyo musimboti, maitiro, mamiriro ekushandisa uye zvisingakwanisi nzira yega yega yekurapa inoongororwa, uye maitiro ekusimudzira ebhoti pamusoro pekurapa tekinoroji mune ramangwana inokurukurwa.

Sechisimbiso chinoshandiswa zvakanyanya mumichina yemidziyo, mhando, kusimba uye kutakura kugona kwemabhaudhi kwakakosha zvakanyanya pakuchengetedza mashandiro emidziyo. Zvisinei, mabhoti anowanzotarisana neoxidation, rust, corrosion uye mamwe matambudziko panguva yekushandiswa, izvo zvisingazongoderedza kushanda kwemabhoti, asiwo zvinogona kukanganisa kugadzikana kwese mechanical system. Nokudaro, kurapwa kwepamusoro kwemabhoti kunonyanya kukosha. Iri bepa rine chinangwa chekukurukura nezve mamiriro, maitiro uye mashandisirwo eiyo bolt pamusoro pekurapa tekinoroji, uye nekupa referensi yekutsvagisa uye mashandisiro mundima dzine hukama.

Pfupiso ye bolt surface treatment tekinoroji

1. Galvanized kurapwa

Galvanizing inowanzoshandiswa bhoti pamusoro pekugadzirisa nzira, nekuvhara pamusoro pebhoti nemucheka we zinc, kuumba chidziviriro chekudzivirira, zvinobudirira kudzivirira pamusoro pebhoti oxidation uye corrosion. Galvanizing kurapwa inokamurwa inopisa dip galvanizing uye magetsi galvanizing. Kupisa dip galvanizing dips mabhaudhi mune yakanyungudutswa zinc mhinduro kuti iite yakakora zinc layer, yakakodzera kune ekunze nharaunda uye maapplication anoda kusimba kwepamusoro; Electrogalvanizing inoshandisa musimboti we electrolysis kuisa zinc layer yakatetepa pamusoro pebhaudhi, iyo inokodzera nharaunda yemukati uye nguva ine yakaderera yehupenyu sevhisi zvinodiwa. Galvanizing haingonatsiridzire kusadzivirirwa kwemabhoti, asi zvakare inowedzera aesthetics yavo. Nekudaro, iyo yekupfeka inogona kuburitsa hydrogen embrittlement pasi pemamwe mamiriro, ayo anokanganisa kusimba uye kuchengetedzeka kwebhaudhi. Pamusoro pezvo, iyo galvanized process inogona kuburitsa tsvina yemvura, gasi remarara uye zvimwe zvinosvibisa, izvo zvinoda kugadziriswa nemazvo kuzadzisa zvinodiwa zvekuchengetedza nharaunda.

2. Electroplating

Electroplating ndiyo imwe yenzira dzinoshandiswa zvakanyanya mukurapwa kwebhaudhi. Nekuisa dhizaini yesimbi yekuputira pamusoro pebhaudhi, senge chromium, nickel, nezvimwewo, iyo corrosion resistance, kuoma uye aesthetics yebhaudhi inogona kuvandudzwa. Mabhaudhi anobatwa nechromium plating akadzikama zvakanyanya mumhepo, haasi nyore kudzima uye kurasikirwa nekupenya, uye ane kuoma kwakanyanya uye nekupfeka kwakanaka kuramba. Chromium plating inowanzo shandiswa kushongedza nekuvandudza kushorwa kwemabhaudhi, asi haiwanzo shandiswa muminda yemaindasitiri uko kushorwa kwecorrosion kwakakwira zvakanyanya. Nickel plating kurapwa inogona kuwedzera corrosion resistance yemabhaudhi uye kuvandudza aesthetics yavo.Nickel coating ine yakanaka ductility uye kuoma, iyo inokodzera zviitiko nepamusoro zvinodiwa pabhaudhi.

3. Kumwaya mushonga

Spray treatment inzira iyo pendi inopfapfaidzwa zvakafanana paboltpamusoro nepfuti yekupfapfaidza.Kupfapfaidza hakungonakidzi chitarisiko chebhaudhi, asi zvakare kukwidziridza kushora kwayo.Mitoo yakajairika yekupfapfaidza ijecha, kupfapfaidza kupenda, kumwaya polyimide zvichingodaro.Pakati pavo, mushonga wekupenda wekupfapfaidza unoshandiswa zvakanyanya muzvigadzirwa zvemagetsi nemamwe maindasitiri nekuda kweruvara rwakapfuma uye kuvaka kuri nyore.Zvakanakira kupfapfaidza kurapwa zviri nyore kuvaka, mutengo wakaderera, uye unogona kusarudza akasiyana mavara uye zvinhu zvinoenderana nezvaunoda.Nekudaro, iko kunamatira uye kusimba kwepfapfaidzo coatings inogona kunge isina kunaka se electroplating uye galvanizing marapiro.

4. Kurapa kwekupisa

Kupisa kupisa inyanzvi kuburikidza nekushandura kuoma uye kusimba kwebhoti pamusoro.Kuburikidza nekudziya, kupisa uye kutonhora maitiro, chimiro chebhoti chinogona kuvandudzwa, uye kupfeka kwayo kuramba uye kusimba kwesimba kunogona kuvandudzwa.Kurapa kwekupisa kunonyanya kukodzera kutakura mitoro mikuru yemagetsi kana kuchinja kwekushisa kwakanyanya, zvakadai semhepo, mauto uye mamwe minda.Nekudaro, iyo yekupisa yekurapa maitiro inogona kutungamira kune shanduko muhukuru hwebhoti, ichida kuomarara kudzora kwemaitiro paramita kuti ive nechokwadi chemhando.

5. Mamwe maitiro ekugadzirisa

Pamusoro peiyo yakajairika yepamusoro yekurapa tekinoroji, kune akati wandei mamwe matekinoroji anoshandiswawo zvakanyanya mumunda webolt surface treatment.Semuenzaniso, iyo phosphating process inoitwa nekunyudza mabhaudhi mune yakakwira-tembiricha mhinduro ine phosphoric acid uye dihydrogen phosphate kuumba crystalline phosphating firimu inoumbwa nephosphate precipitates.Phosphating firimu ine yakanaka anti-corrosion properties, asi inoda kushandiswa ne-anti-rust mafuta kuti ibudirire kuwedzera hupenyu hwebasa remabhoti.Pamusoro pezvo, tekinoroji nyowani dzekurapa pamusoro senge zincizing kurapwa uye dacromet kurapwa zvishoma nezvishoma zvakagamuchira kutariswa uye kushandiswa.

Mamiriro ekushandisa uye ongororo yekumisa

Sarudzo yebhaudhi yepamusoro yekurapa tekinoroji zvinoenderana neiyo chaiyo yekushandisa nharaunda uye kuita zvinodiwa. Semuenzaniso, muMarine engineering, mabhaudhi anoda kugara achiiswa mumvura yegungwa, uye munyu nehunyoro zvine simba guru pakuora kwemabhaudhi. Kugadziriswa kwepamusoro kwemabhaudhi akadaro kunowanzo kusarudzwa nepamusoro-galvanized kana titanium alloy coating kuti ipe yakasimba anti-corrosion dziviriro. Mune tembiricha yepamusoro yezvigadzirwa zveindasitiri, zvinodikanwa zvebhaudhi repamusoro kurapwa zvinobhadhara zvakanyanya kune yakakwira tembiricha kuramba uye kupisa kuneta kuramba, uye kupisa kurapwa kana titanium coating tekinoroji inoshandiswa kuvandudza kupisa kwekudzivirira kwemabhoti.

Nekudaro, imwe neimwe nzira yekurapa pamusoro ine painogumira.Semuyenzaniso, kunyange zvazvo galvanized kurapwa iri yakaderera mutengo uye yakanaka anti-corrosion kuita, inogona kubudisa hydrogen embrittlement chiitiko uye kwezvakatipoteredza kudzivirira matambudziko;Kunyangwe kurapwa kwe electroplating kunogona kuvandudza kuoma uye aesthetics yemabhaudhi, mutengo wakakwirisa uye kupfekedza kunogona kudonha pasi pemamwe mamiriro. Kupfapfaidza kurapwa kuri nyore kugadzira, asi kunamatira uye kusimba kunogona kunge kusina kukwana. Naizvozvo, mumashandisirwo anoshanda, zvinodikanwa kuti usarudze tekinoroji yakakodzera yekurapa kwepamusoro zvichienderana nemamiriro chaiwo nekutarisa zvinhu zvakasiyana.

Future development trend

Nekuenderera mberi kwekuvandudza kwesainzi uye tekinoroji,boltpamusoro pekurapa tekinoroji zvakare inogara ichigadzira uye ichivandudzwa.Mune ramangwana, tinogona kuona kuti kuenderera mberi kwekubuda kwezvinhu zvitsva uye maitiro matsva anosimudzira kuvandudzwa kwebhoti yepamusoro yekurapa tekinoroji.Semuenzaniso, nekuvhara pamusoro pebhaudhi ine nanoscale coating, iyo nanocoating tekinoroji haingogone kuvandudza kurora kwayo, asi zvakare inosimudzira yayo antibacterial uye antioxidant masimba.Pamusoro pezvo, tekinoroji ine hushamwari hwepamusoro yekurapa tekinoroji inozovewo imwe yemafambiro ebudiriro yekusangana nekuwedzera kuomesera kwezvakatipoteredza zvinodiwa.

mhedziso

Bolt pamusoro pekurapa tekinoroji inoita basa rakakosha mukuvandudza kuita kwebhoti uye kuwedzera hupenyu hwebasa. Mupepa rino, maitiro akasiyana-siyana ekugadzirisa pamusoro pemabhoti anoongororwa, kusanganisira galvanizing, electroplating, spraying, heat treatment, etc., uye nheyo, maitiro, mamiriro ekushandiswa uye zvisingakwanisi nzira imwe neimwe yekurapa inoongororwa. Mune ramangwana, nekuenderera mberi kwekubuda kwezvinhu zvitsva uye maitiro matsva uye kuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza, tekinoroji yebhaudhi yepamusoro yekurapa inovandudza munzira yekunyanya kushanda, kuchengetedza kwezvakatipoteredza uye kusingaperi.
