Mabhenefiti Akasarudzika eWhite Corundum muKupukuta Kwezvishongo
Nyanzvi dzemabasa ekugadzira zvishongo dzine chirevo chinoti: “Zvikamu zvitatu zvechigadzirwa, zvikamu zvinomwe zveunyanzvi.” Dombo rematombo remhando yepamusoro uye muunganidzwa wesimbi dzinokosha dzakagadzirwa neunyanzvi zvinoshandurwa kuita basa reunyanzvi rinoyevedza mubhokisi rekuratidzira, uye matanho ekupedzisira ekupukuta ndiwo "kubata kwekupedzisa." Uku "kubata kwekupedzisa" kunoda hunyanzvi hwakakura. Zvishandiso zvinoshandiswa uye huwandu hwesimba rinoshandiswa zvese zvinoenderana nehunyanzvi hwemhizha. Uye kana zvasvika pakugadzira zvinhu, pane chakavanzika chakachengetedzwa muindasitiri - corundum chena. Kusiyana neupfu hwedhaimani, hunoyevedza uye hunokosha, kana mamwe makemikari, akafukidzwa nechakavanzika, zvakaita se "shamwari yekare" inogara yakasimba uye yakavimbika, ichivimba nehunyanzvi hwayo hwakasimba uye kunyatsotarisa kune zvakadzama kuti irambe yakasimba munzvimbo yayo munyika yakavanzika yekupukuta zvishongo.
Chinhu ichi, chine zita rayo rinonzwika seremaindasitiri, "white corundum," chingaratidzika sechinhu chinoshandiswa mufekitori kushanda nemabhuroko makuru esimbi. Asi handizvo zvachose. Kana ukachikwiza pakati peminwe yako, kupukuta kwemhando yepamusoroupfu hudiki hwecorundum chena Yakatsetseka sehupfu hwakanakisa, ine kupenya kunotonhorera, kwakaita seporcelain. Chimiro chayo chechokwadi ikristaro yealumina yakachena kwazvo, inowanikwa nekunyunguduka kwekupisa kwakanyanya, kupwanywa nekunyatsogadzirwa, uye kurongwa. Ine kuomarara kwakanyanya, yechipiri kune dhaimani nesilicon carbide, asi hunhu hwayo hwakapfava uye hunodzorwa kupfuura "mapfupa maviri akaomarara." Ndiwo chaiwo hunhu uhwu "hwakaoma asi husina kuomarara" hunoita kuti ive "yakazara" pakubata zvishongo zvakasiyana-siyana zvine hunyoro.
Sei zvichinzi "zvakazara"? Ngatizvitsanangure.
Chekutanga, "inoziva" zvinhu, kana kuti, "inoziva chinhu chacho." Muindasitiri yezvishongo, zvinhu zvakasiyana-siyana zvikuru: zvinhu zvakaoma zvakanyanya zvakaita sesafire neruby, zvinhu zvakaoma zviri pakati nepakati zvakaita sejadeite nenephrite, uye mhando dzakasiyana dzegoridhe rekarati, platinum, nesirivha. Haugone kushandisa "ruler" imwe chete kuyera zvese. Kubatsira kwealumina chena yakasanganiswa kuri mukukwanisa kwayo kugadzirisa zvinhu zvakasiyana-siyana nekugadzirisa kunaka kwezvikamu zvayo (zvinozivikanwa se "mesh"). Zvidimbu zvine makomba (semuenzaniso, 600 kusvika 1000 mesh) zvinoshandiswa pakutanga "kupukuta," kubvisa nekukurumidza mavanga akaomarara nemipendero yakapinza inosara mushure mekucheka - maitiro anonzi "kunyorovesa." Muzvikamu zvekupedzisira, kunyange hupfu hwakatsetseka hunoshandiswa, senge 2000, 3000, kana kunyange makumi ezviuru zvemambure. Panguva ino, basa rayo guru harisi rekucheka, asi, kuburikidza nekukweshana kwezvidimbu zvidiki zvisingaverengeki, zvishoma nezvishoma "inobvisa" mavanga madiki pamusoro, zvichiita kuti ive nechiedza chisina kujeka (matte) kana kuti yakaita segirazi. Alumina chena yakasanganiswa inogona kubata shanduko yese kubva pa "rough" kuenda ku "refined," nekuchinja-chinja kwakapfava, shanduko shoma dzezvinhu, uye nyore kushandisa kune mhizha dzine ruzivo.
Chechipiri, "yakachena." Izvi zvakakosha chose. Chii chinonyanya kutyiwa pakupukuta zvishongo? Kusvibiswa uye "kubuda kwemavara." Zvimwe zvinhu zvekupukuta zvine ruvara rwakasviba kana kuti zvine tsvina. Munguva yekupukuta nekukurumidza, tembiricha yepamusoro inogona "kuvhara" ruvara kana tsvina muzvidimbu zvidiki zvedombo kana magadzirirwo esimbi, zvichikanganisa basa - maitiro anozivikanwa muindasitiri se "kudya tsvina."Alumina chena yakasanganiswa, kune rumwe rutivi, ine ruvara ruchena uye yakasimba pamakemikari, haichinji nyore kunyangwe pakupisa kwakanyanya. Kana ikashandiswa pakupukuta, kunyanya pakupukuta simbi chena dzine girazi rakawanda (platinum, goridhe chena, sirivha) kana matombo anokosha asina ruvara kana ruvara rwakajeka (dhaimani, kristaro, safaya ane ruvara rwakajeka), inoita kupenya kwechokwadi kwakachena "kutonhora," pasina kuwedzera tsvina, ichichengetedza ruvara rwakachena rwechinhu chacho nemoto. "Kuchena" uku inzira yegoridhe muindasitiri yezvishongo.
Uyezve, "inonyorova uye inodzorwa." Kupolisha hakusi kwesimba guru, asi hunyanzvi; ndeyekushandisa kumanikidza zvinobudirira pasina kukuvadza chinhu chacho.alumina chena yakasanganiswa, kunyanya upfu hwakatsetseka hwemambure akakwirira, hune maumbirwo akajairwa (kunyangwe hwakatyoka, hwakagadziriswa) uye mipendero yakafanana. Kana ikashandiswa nependi yekupukuta yakakodzera (mafuta) pavhiri rekupukuta kana jira, inoumba "chikamu chekucheka chidiki" chakafanana uye chakasimba. Kumanikidzwa kunoshandiswa nemhizha ine hunyanzvi kunogona kupfuudzwa zvakaenzana uye zvishoma nezvishoma pamusoro pezvishongo kuburikidza nenzira iyi. Kupenya kunobva kwacho "mhenyu," kupenya kunofambira mberi, kunopenya kunopenya kubva mukati, pane kupenya kwepamusoro, kwekugadzira. Kunyanya pakubata zvishongo zvegoridhe zvakakombama, zvakavezwa, kana zvakagadzirwa zvakanaka, hunhu hwakanaka hweagate chena yakasanganiswa hunoratidza hunyanzvi. Inopinda muzvinhu zvidiki, ichiunza chiedza kumakona ese, pane kunyorovesa zvinhu zvese.
Ehe, kunyange zvinhu zvakanakisisa zvinoenderana nemushandisi. Nyanzvi dzemabasa emaoko dzinobata agate chena yakasanganiswa seshamwari yekare. Upfu hwakasiyana hwegrit hunosanganiswa nemafuta akasiyana, uye kugadzikana kwahwo kunofungwa nokungwarira; zvinhu uye kuoma kwevhiri rekupukuta, kumhanya kwekutenderera, kumanikidzwa nekufamba kweruoko, uye kunyange kugadzikana kwemhizha panguva yekupukuta zvese zvinokanganisa kupenya kwekupedzisira. Vanowanzoti, "Agate chena yakasanganiswa haitauri, asi chiedza chayo chinotaura zvakawanda." Ibate nokungwarira, uye icha "taura" kupenya kwayo kwakanyanya, kwakajeka, uye kunogara kwenguva refu pazvishongo.
Saka, kana uchikwezvwa nekupenya kunoshamisa kwechinhu chezvishongo chiri mubhokisi rekuratidzira, kupenya ikoko kungave kwakapfuura nemaitiro akawanda, kubva kujecha rakaomarara kusvika kuhupfu hwakatsetseka. Uye padanho rekupedzisira rekupa iyo kutarisa kwakadzama uye kwakajeka, agate chena yakasanganiswa—chinhu ichi “chinyoro asi chakasimba”—chinogona kutamba basa rakanyarara asi rakakosha. Hachina kupenya kwakanyanya sehupfu hwedhaimani, asi chine pfungwa huru yerupo uye kubatanidzwa; hachitsvage kupenya kwepakarepo, asi chinokunda pakumutsa zvishoma nezvishoma kupenya kwechinhu chacho pachacho.
Zvakafanana nemhizha inonzwisisa zvakadzama hunyanzvi hwe "kunyorovesa zvishoma nezvishoma," ichishandisa mwoyo murefu nekuchena kupukuta zvishongo zvese kuti iratidze chiedza chayo chakasiyana, chekupedzisira, uye chinofamba zvakanyanya chehupenyu. Chiedza ichi hachipenye, asi chinobaya mwoyo. Pamwe uku ndiko kudziya kwehunyanzvi, kuchiyerera chinyararire pakati pehupfu hwakatsetseka nevhiri rinotenderera.
