Tose tinoziva kuti simbi yepenzura yakapfava uye iri nyore kupwanya. Kune chinhu chakadaro chakagadzirwawo nekabhoni sesimbi yepenzura, asi ndicho chinhu chakaoma kupfuura zvose pasi rose, icho chiri dhaimani.
Nekuda kwekuoma uye kushomeka kwemadhaimani, vanhu vanga vachiaona sematombo anokosha kubvira kare, uye dhaimani mushure mekucheka nekupukuta inonzi dhaimani, inova imwe yematombo anokosha kwazvo pasi rose.
Kuomarara kwedhaimani kwakanyanya. Inogona kudhirowa zviratidzo pazvinhu zvinenge zvese. Dhaimani yakapinza uye haisi nyore kuipisa. Saka inoshandiswawo mukugadzira, zvakaita sekuisa dhaimani pamidziyo yakasiyana-siyana yekugadzira maturusi ekukuya nekucheka. Maitiro aya ekugadzira dhaimani yakaputirwa nemagetsi.
Dhaimani yakaputirwa nemagetsi
Dhaimani yekuisa electroplating yakavakirwa panheyo yekuisa electroplating. Jecha redhaimani rinoiswa pachinhu chebasa ne nickel. Chikamu chimwe chedhaimani chichaiswa pa substrate, uye chimwe chikamu chichaiswa pachena pamusoro kuti chigadzire layer yakasimba uye inodzivirira kupera.
Chinangwa chedhaimani yakaputirwa nemagetsi ndechekuwedzera kugona kwekucheka nekukuya nekuisa zvidimbu zvedhaimani zvakakora pamusoro pesimbi. Zvishandiso zvakasiyana-siyana zvekukuya zvakagadzirwa netekinoroji yedhaimani yakaputirwa nemagetsi zvinoshandiswa zvakanyanya mumichina, magirazi, zvinhu zvekuvaka nedzimwe nzvimbo dzeindasitiri.
Kuumbwa kwedhaimani kunofanirwa kugadzirwa munzvimbo yakakosha, saka kugadzirwa kwedhaimani kwakanyatsogadzirwa uye kubuda kwacho kushoma. Dhaimani yechisikigo haigone kugutsa kudiwa, saka dhaimani yakaputirwa nemagetsi inogadzirwa nezvidimbu zvedhaimani zvakagadzirwa.
Nhoroondo yekukura kwekukuya
Vanhu vane nhoroondo yakareba yekushandisa maturusi akasiyana-siyana ekukuya kuti vagadzire zvinhu. Kare kare, vanhu vekare vaishandisa matombo akapinza, mapfupa emhuka, tsvimbo nezvimwe zvishandiso pakuvhima nekucheka chikafu, icho chiriwo chishandiso chekutanga chekukuya.
Zvakanyorwa kuti munguva yeYuan Dynasty, kwaive nechishandiso muChina chaishandisa rabha yechisikigo kunamira upfu hweganda paganda remakwai kuti rikweshe. Ichi ndicho chishandiso chekutanga chakanyorwa chakaiswa mukati.
Kubva pakawanikwa simbi dzakasiyana-siyana dzakadai sebhuronzi, vanhu vakatanga kushandisa hunhu hwavo hwakasimba uye hwepurasitiki kugadzira simbi idzi kuita zvishandiso zvakasiyana-siyana uye kudzishandisa zvakanyanya mumabasa akasiyana-siyana ekukuya. Kubva ipapo, vanhu vakapinda munguva itsva yekushandisa kukuya simbi.
Munguva dzazvino, nekukura kuri kuita kugadzirwa kwemaindasitiri, kuoma kwezvinhu zvakagadzirwa kuri kuramba kuchiwedzera, uye maturusi ekukuya simbi haachakwanisi kugutsa zvinodiwa, saka vanhu vakatanga kutsvaga zvinhu zvakaoma sezvinhu zvinogumbura.
Saka kune zvinhu zvekukuya zvakaita se natural corundum, artificial silicon carbide uye artificial diamond zvine kuoma kwakanyanya izvo zviri kushandiswa zvakanyanya mazuva ano. Mushure mekukuya zvinhu izvi kuita zvidimbu zvidiki, zvinopiswa kana kuiswa pane zvimwe zvinhu zvesimbi kuti zvigadzire chimiro chakati chezvishandiso zvekukuya, kuitira kuti zviitwe kugadzira kukuya.
Hunhu hwedhaimani yakarukwa nemagetsi
Zvigadzirwa zvakagadzirwa nedhaimani yakaputirwa nemagetsi zvinoumbwa nezvikamu zviviri: workpiece uye diamond coating. Nokudaro, nzira iyi yekuisa dhaimani yakaputirwa nemagetsi inogona kugadzira maturusi akasiyana-siyana ekukuya ane chimiro chisina kurongeka, saizi diki nediki uye kunyatsoita basa nemazvo.
Dhaimani yakaputirwa nemagetsi inowanzoshandisa nickel sechisungo pakati pezvidimbu zvedhaimani ne substrate. Ichanyatsobatanidza 1/2 kana 2/3 yedhaimani pabasa, uye chifukidziro chichava chakaoma zvikuru. Izvi zvichaita kuti dhaimani yakaputirwa isaparare zvakanyanya, uye dhaimani haizodonhe nyore nyore.
Nekuti kuomarara kwedhaimani kwakanyanya uye kupinza kwezvidimbu zvedhaimani kunogona kuramba kuripo kwenguva yakareba, kushanda zvakanaka kwezvishandiso zvakasiyana-siyana zvekukuya zvakagadzirwa nedhaimani yakaputirwa nemagetsi kuchave kwakanyanya uye kucharamba kuchishandiswa.
Mukugadzirwa kwedhaimani yakaputirwa nemagetsi, nzira yekuisa dhaimani mukupisa kwakaderera mushure mekuiswa kwemagetsi inotorwa, saka haizoburitse kupisa kwakanyanya uye kumanikidzwa kwakanyanya padhaimani, uye haizove nemhedzisiro padhaimani pachayo, izvo zvinoitawo kuti mhando yedhaimani isaderedzwe, uye zvinobatsira zvikuru pakuvandudza kunaka kwekukuya.
Kuyerera kwemadhaimani emagetsi
Zvinhu zvedhaimani
Sarudza nhamba inoenderana yedhaimani mesh zvichienderana nekunyatso dikanwa kwechishandiso chedhaimani chakagadzirwa nemagetsi, uye dhaimani yakagadzirwa icharatidza polyhedron ine kona yedhaimani pasi pemaikorosikopu, uye icharatidza ruvara rweyero-girini.
Kuti dhaimani iomeswe nemagetsi ive nemhando yepamusoro, muchina wekugadzira magineti uchashandiswawo kubvisa tsvina dzakasiyana-siyana kubva muzvidimbu zvedhaimani kuti uve nechokwadi chekuti dhaimani yacho yakachena.
Kubvisa mafuta
Shandisai industrial alkali kubvisa mafuta, isa caustic soda mumvura woifashaidza kwemaminitsi makumi matatu, wozoigeza nemvura yakasanganiswa nemvura kaviri kusvika katatu kubvisa mavara emafuta pamusoro pedhaimani.
Chishandiso chedhaimani chakagadzirwa nemagetsi chinofanirawo kubviswa mafuta. Kazhinji, chishandiso chinoiswa mu ultrasonic cleaner ne caustic soda, uye mvura inodziiswa kuti inyungudise caustic soda, uye kuchenesa kwe ultrasonic kunoitwa kwemaminitsi makumi matatu.
Kuisa jira pakutanga
Kuti dhaimani ne substrate zvikwanise kubatanidzwa zvakasimba, zvakakosha kuputira coating yakaputirwa nemagetsi pamusoro pechinhu chebasa usati waisa dhaimani nemagetsi.
Electrolyte inodziiswa kusvika pa50 ℃, uye workpiece inoiswa mubhavhu re plating rine simba. Mushure mekuita kwesimbi nickel ne plating solution, nickel ion inosara pamusoro pe workpiece, yoita plate layer yakatetepa.
electroplate
Kuisa dhaimani pamusoro pechinhu chakaiswa electroplated, pane nzira mbiri: nzira yekuisa jecha uye nzira yekudonhedza jecha. Nzira yekudonhedza jecha inogona kupedzisa jecha panzvimbo imwe chete panguva imwe chete, saka yakakodzera zvigadzirwa zvedhaimani zvakaiswa electroplated divi rimwe chete; Nzira yekuisa jecha ndeyekuisa zvigadzirwa zvinoda dhaimani rakaiswa electroplated mujecha redhaimani, saka yakakodzera zvigadzirwa zve cylindrical kana zvisina kujairika.
Zvisinei, misimboti yavo yakafanana. Mushure mekunge mhinduro ye electroplating uye workpiece yaiswa magetsi, zvidimbu zvedhaimani zvichaiswa pa workpiece yakatoiswa kare. Pasi pekushanda kwesimba remagetsi, nickel ichaora yoburitsa maatomu enickel, ayo achaiswa pa workpiece nezvidimbu zvedhaimani. Dhaimani riri pamusoro richaputirwa zvishoma nezvishoma kuti riite dhaimani.
Geza woomesa
Mushure mekuputira nemagetsi, gezai chigadzirwa nemvura yakachena, nekuti pachava nemvura yemagetsi nedhaimani pakati pedhaimani; Pakupedzisira, mvura iri pamusoro pechigadzirwa inogona kupwanyika nemhepo inopisa, uye chigadzirwa chedhaimani chakagadzirwa nemagetsi chinopedzwa.
