Enamel

Enamel,sekushongedza kwepamusoro-kwenguva refu uye zvinhu zvekudzivirira, zvinoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri uye hupenyu hwezuva nezuva.Haisi chete yakanaka uye yakasimba, asiwo ine yakanaka kugadzikana kwekemikari uye kusagadzikana kwekuora.Kubva pakuona kwekugadzirwa kwemaindasitiri, maitiro ekugadzira enamel inzira yakaoma inosanganisa sainzi yemidziyo, engineering yemakemikari, uye yakanaka yekugadzirisa tekinoroji, inosanganisira kusarudzwa kwezvinhu, kugadzirira, kupfekedza, uye kupfura.

1. Tsanangudzo uye kuumbwa kweenamel

Enamel chinhu chakaumbwa chinoumbwa nekunyungudutsa inorganic girazi zvinhu pasimbi matrix uye nekuinyudza pakupisa kwakanyanya.Izvo zvakakosha zvinosanganisira glaze (silicate, borate, nezvimwewo), colorants, fluxes, uye inosimbisa vamiririri.Pakati pavo, glaze ndiyo nheyo yekugadzira iyo enamel layer, iyo inosarudza muviri uye makemikari zvinhu zveenamel;Mavara anoshandiswa kusanganisa mavara;Flux inobatsira kuyerera kwe glaze panguva yekupisa, kuve nechokwadi chekupenya kwe glaze;Enhancers inowedzera simba remagetsi uye kunamatira kwekuputira.

2. Kugadzirira kwezvinhu zvakasvibiswa

Nhanho yekutanga mukugadzirwa kweenamel ndiko kusarudzwa uye pretreatment yezvakagadzirwa.Iyo simbi substrate inowanzogadzirwa nesimbi, simbi, aluminium, nezvimwewo, uye iyo yakakodzera zvinhu uye ukobvu zvinofanirwa kusarudzwa zvinoenderana nezvinodiwa zvekushandisa.Kugadzirira kwe glaze kunosanganisira kusanganisa zvinhu zvakasiyana-siyana zvakasvibirira zvakaenzana, kuzvikuya kune imwe nhanho yehunyoro, kuve nechokwadi chekufanana uye kunaka kwekuputira kwekupedzisira.Panguva ino, kuongororwa kwakasimba kwezvinhu zvakasvibirira kunodiwa kuti ive nechokwadi chekuti hapana kusvibiswa, kuti zvisazokanganisa kunaka uye kuita kweiyo enamel layer.

3. Kurapa kwepamusoro

Usati waputira, iyo simbi substrate inoda kucheneswa uye kubatwa pamusoro kubvisa girizi, oxide ganda, uye zvimwe zvinosvibisa.Nzira dzakajairika dzinosanganisira degreasing, acid washing, phosphating, etc. Iyi nhanho yakakosha pakuvandudza kusimba kwekubatana pakati pe enamel layer nesimbi substrate.

4. Enamelling process

Iyo yekupfekedza nzira inogona kukamurwa muzvikamu zviviri: yakaoma nzira uye nzira yekunyorova.Dry nzira kunyanya zvinosanganisira electrostatic upfu pfapfaidzo uye fluidized pamubhedha kunyudzwa rukuvhute, izvo zvakakodzera guru-mwero otomatiki kugadzirwa, anogona zvinobudirira kudzora coating ukobvu, uye zvakatipoteredza ushamwari.Iyo nzira yekunyorova inosanganisira roll coating, dip coating, uye kupfapfaidza coating, izvo zvakanyanya kufanirwa kune yakaoma maumbirwo uye diki batch kugadzirwa, asi inotarisana nekusvibiswa kwezvakatipoteredza uye kusaenzana kwekusagadzikana matambudziko.

5. Kusvirwa

Chigadzirwa chakavharidzirwa chinoda kupiswa pakupisa kwepamusoro, iyo inhanho inokosha pakugadzira yepamusoro-yepamusoro enamel layer.Tembiricha yekupfura inowanzova pakati pe800 ° C uye 900 ° C, zvichienderana neyakajeka fomula uye substrate mhando.Munguva yekupisa, glaze inonyunguduka uye yakaenzana inovhara pamusoro pesimbi.Mushure mekutonhora, inoumba yakaoma uye yakatsetseka enamel layer.Kuita uku kunodawo kudzora kwakasimba kweyero yekudziya, nguva yekudzivirira, uye chiyero chekutonhora kudzivirira kuitika kwehurema hwakaita sekutsemuka uye mabhuru.

6. Kuongororwa kwehutano uye post-processing

Mushure mekupfurwa, zvigadzirwa zveenamel zvinoda kuongororwa kwakasimba kwemhando, kusanganisira kuongororwa chitarisiko, corrosion resistance test, mechanical simba test, etc. Zvigadzirwa zvisina kukodzera zvinoda kugadziriswa kana kuraswa.Mukuwedzera, zvichienderana nekushandiswa kwechigadzirwa, mamwe matanho akadai sekubatanidza uye kurongedza anogona kudiwa.

7. Munda wekushandisa

Enamel yakashandiswa zvakanyanya muminda yakawanda nekuda kwekuita kwayo kwakanaka.Muindasitiri yemidziyo yemumba, yakadai sehovhoni, muchina wokuwachisa, mahita emvura, nezvimwewo, iyo enamel liner haingofadzi chete uye iri nyore kuchenesa, asiwo inoshingirira kune tembiricha yakanyanya uye ngura.Mukushongedza kwezvivakwa, enamel simbi mahwendefa anowanzoshandiswa kumadziro ekunze, tunnels, subway stations, nezvimwewo nekuda kwemavara avo akapfuma uye kusagadzikana kwemamiriro ekunze.Pamusoro pezvo, midziyo yekurapa, makemikari emidziyo uye mamwe minda zvakare anoshandisa zvakanyanya zvigadzirwa zveenamel, achitora mukana wekugadzikana kwavo kwekemikari uye hunhu huri nyore hwekuuraya hutachiona.

Mhedziso

Pakazara, kugadzirwa kweindasitiri yeenamel inzira yakaoma inobatanidza hunyanzvi hwechinyakare nehunyanzvi hwemazuva ano.Zvigadzirwa zvaro zvakapedzwa hazvingoratidzi kusanganiswa kwakakwana kweaesthetics uye kuita, asi zvakare zvinoratidza kufambira mberi kwesainzi yezvinhu uye tekinoroji yekugadzira.Nekuenderera mberi kwekuvandudza tekinoroji, zvigadzirwa zveenamel zviri kufamba zvichienda kune imwe nharaunda ine hushamwari, inoshanda, uye ine mabasa mazhinji kutungamira, zvichiramba zvichisangana nezvinodiwa zveminda dzakasiyana.

Chero kubvunza nezve Casting, Forging kana Machining zvikamu, ndapota inzwa wakasununguka kutibata nesu chero nguva.
