Basa Rinokosha reWhite Fused Aluminum Sandblasting muPretreatment yeSimbi
Isu tiri muindasitiri iyi tinoziva kuti zvikamu zvesimbi, sevanhu, zvinoda kugadzirira kwakakwana tisati tabuda kunosangana nevaenzi. Kana zvakafukidzwa nemafuta, ngura, uye pendi yekare, munhu wese achadzungudza misoro yake. Danho rekutanga mu "kugadzirira" uku kugadzirira, uye kuputira jena rakagadzirwa nearuminiyamu ndiro chinhu chakakosha mukuita uku. Nhasi, tichatsanangura zvese tokurukura kuti chinhu ichi chinoita sei basa racho risingatsivike mukugadzirisa simbi.
I. Haisi "Jecha" rese riri Chena Yakasanganiswa Aluminum: Chii Chinoita Kuti Rive Nesimba Kwazvo?
Vatsva muindasitiri iyi vangafunga kuti kuputira jecha kungoshandisa jecha kurova pamusoro pesimbi, chii chinoshamisa pairi? Eya, maonero asina musoro. Edza kushandisa jecha rerwizi kana jecha requartz? Zvinhu izvozvo hazvina kuoma zvakakwana, zvinoburitsa guruva rakawanda, hazvina kunaka kuhutano hwevashandi, uye zvinowanzosiya zvasara pamusoro mushure mekuputira. Alumina chena yakasanganiswa yakasiyana; inyanzvi chaiyo.
Funga nezvazvo:alumina chena yakasanganiswai corundum yakagadzirwa, yakachena kwazvo, uye sezvinoreva zita rayo, chena chaiyo. Asi yakasimba zvikuru! Kuoma kwayo kuri pakati pezvinhu zvakanyanya kusimba, iri yechipiri kune silicon carbide nedhaimani. Izvi zvinoreva kuti kana ikarova pamusoro pesimbi, inoshanda zvikuru, ichicheka marara akasanganiswa nekumhanya kwemheni.
Uyezve, yakagadzikana zvakanyanya pamakemikari, haina silicon yakasununguka, uye guruva rayo rinobatsira mapapu. Inogadzira zvidimbu zvakaenzana, kusiyana nemamwe mabrasives anogona kugadzira kupera kwakaoma. Chinonyanya kukosha ndechekuti haikwezve guruva kana tsvina; inoramba yakachena uye haipe tsvina pamusoro pesimbi, inova ndiyo nyaya huru pakuisa machira kana plating gare gare. Saka, kuisarudza sechinhu chekutanga kunopa rugare rwepfungwa.
II. Maitiro Ayo Ane Zvikamu Zvitatu: Kuchenesa, Kukwesha, uye Kusimbisa
Kuputira alumina chena kwakasanganiswa kunonyanya kutarisisa maitiro matatu makuru ekugadzirisa usati watanga: kuchenesa, kukwesha, uye kusimbisa. Ngatikurukurei chimwe nechimwe.
Chinongedzo Chekutanga: Kuchenesa Zvakakwana, Pasina Kusiya Matambudziko Gare gare
Ichi ndicho chinhu chiri nyore, asi chinonyanya kudiwa. Zvikamu zvesimbi zvinobva mugayo resimbi, kana kuti zvinochengetwa mudura kwenguva yakareba, zvine pamusoro pe "bhegi rakasanganiswa": oxide scale (yakaita ngura yebhuruu kana tsvuku-tsvuku), welding slag, mavara emafuta akaomarara, machira ekare… Kugeza neacid yemakemikari hakusi nyore, asi hazvina kunaka kune nharaunda uye zvinogona kutokuvadza substrate. Kukuya nemaoko nevhiri rewaya? Izvozvo hazvishande zvakanaka.
Kuputira alumina chena yakasanganiswa hakuna basa nazvo. Kufambiswa nekumanikidzwa kwakanyanya kwemhepo inomanikidza, mamiriyoni ezvidimbu zvidiki zvealumina zvakasanganiswa, zvakaita semabara, "whoosh," zvichienda pamusoro pebasa. Izvi hazvisi kungonyepedzera chete; inzira chaiyo yekubvisa ganda. Oxide scale uye welding slag hazvisi chinhu kunze kwe "paper tigers" dziripo, dzinopwanyika pakarepo dzobva dzabviswa. Mushure mekupfapfaidza, tarisa zvakare! Ruvara rwesimbi yechisikigo rwunoonekwa, rwakachena uye rwakapfava, setofu ichangobva kugadzirwa - chiono chinofadza. Danho rekutanga rekuchenesa iri rakafanana nekugadzirira "canvas" yakachena yemaitiro anotevera.
Demo Rechipiri: Kukwesha Kwakanaka, Kubata Chifukidziro
Kuchenesa kwakakwana here? Kwete! Fungidzira pamusoro pesimbi yakatsetseka, yakaita segirazi; kana ukapfapfaidza pendi kana kuipenda neupfu, kunamatira kwayo kuchave kwakanaka here? Zvakafanana nekunamira pepanhau pagirazi—rinodonha kana ukangoribata zvishoma. Chishamiso chechipiri chekuchenesa sandblasting chena "kukwesha" pamusoro wakatsetseka uyu.
Hazviparadzi, asi "zvivezwa." Zvinogadzira makomba madiki asingaverengeki, akafanana pamusoro pesimbi, ayo atinodaidza kuti "anchor patterns" kana "roughness." Usarerutsa makomba aya; anowedzera zvakanyanya nzvimbo yepamusoro, sekupa chifukidziro nezviuru zve "maoko" madiki, anoibata zvakasimba. Izvi zvinoguma nekuwedzera kwejometri mukunamatira kwependi nepurasitiki, zvichiita kuti isanyanya kukwesha kana kupwanyika. Mhedzisiro iyi yekukwesha, inoyerwa nemidziyo yehunyanzvi se "roughness," chinhu icho mhizha ine ruzivo inogona kuona nekukurumidza nekubata: "Hmm, basa iri raitwa zvakanaka, pendi inonamira zvakanaka!"
Danho Rechitatu: Kusimbisa Kusingaonekwe, Kuwedzera Nguva Yehupenyu
Danho rechitatu iri rakaita se "simba remukati" - risingaonekwe uye risingabatike, asi mabhenefiti acho ndeechokwadi. Kukanganisa kukuru kwezvikamu zvichena zve corundum pamusoro pesimbi chaizvoizvo inzira "yekushanda inotonhora". Inokonzera kukanganiswa kwe lattice pamusoro pesimbi, zvichikonzera kumanikidzwa.
Chii chinonzi kumanikidzwa kwesimbi? Funga nezvazvo seizvi: zvakafanana nekuisa "bodysuit isingaoneki" pamusoro pesimbi, zvichiita kuti chimiro chemamorekuru esimbi chive chakabatana uye chakasimba. Izvi zvinowedzera simba rekuneta kwesimbi uye zvinowedzera kuramba kwayo ngura, zvichiwedzera hupenyu hwebasa. Kune zvimwe zvinhu zvakakosha, zvakaita semacrankshaft einjini nemidziyo yekumhara yendege, maitiro aya akakosha zvikuru.
III. Hunhu hwebasa racho hunoenderana nekuti unorishandisa sei
Midziyo yacho pachayo inogona kunge yakanaka, asi kuti basa riitwe zvakanaka, zvese zvinoenderana nekuti unoishandisa sei. Kune mazano akawanda.
Kutanga, unofanira kusarudza grit yakakodzera. Grit yakaoma ine mashandisirwo ayo, uye grit yakanaka ine zvayakanakira. Kana uchida kubvisa ngura yakakora kana pendi, unofanirwa kushandisa grit yakaoma, senge 20 kana 30 mesh, kuti uwane simba rakawanda. Kana uchida kuchenesa zvakanaka chete kana kuti pattern yakapfava yeanchor, unofanirwa kushandisa grit yakanaka, senge 80 kana 100 mesh. Haugone kushandisa jecha rimwe chete pazvinhu zvese.
Chechipiri, unofanira kudzora kumanikidzwa kwemhepo nekona. Kana kumanikidzwa kwemhepo kwakaderera zvakanyanya, chirauro chichava chakapfava uye chisina kusimba; kana kumanikidzwa kwemhepo kwakakwira zvakanyanya, chinogona kukanganisa zviri nyore maworkpieces matete kana kutopwanya chirauro, zvichikonzera mhedzisiro yakaipa. Izvi zvinoshandawo kune angle yepfuti yekupfapfaidza. Pakuchenesa kwakajairika, kona ye45 kusvika 70 degrees ndiyo yakakodzera. Kana kona iri diki zvakanyanya, zvinoita sekunge "kukwesha pasi," zvichikonzera mhedzisiro isina kuenzana.
Pakupedzisira, nharaunda inofanira kuchengetwa yakaoma.Alumina chena yakasanganiswayakanaka munzira dzose, kunze kwekuti "inonzwa hunyoro." Kana yanyorova, inobatana zviri nyore, ichivhara nozzle yepfuti yekupfapfaidza, izvo zvinogona kukonzera kunonoka kukuru. Nokudaro, mhepo yedu inofanira kunge yakashongedzwa nemuchina wekuparadzanisa mafuta nemvura, uye tangi rekuchengetera jecha rinofanirawo kudzivirirwa kubva kuunyoro.
Saka, ndapota musafunge nezve alumina chena yakasanganiswakuputika kwejechasebasa riri nyore re "kuchenesa". Mubasa rekugadzirisa simbi, inoshanda zvakanyanya, inoshanda se "muchenesi," "muvezi," uye "mushonga unosimbisa." Inogadzira mhedzisiro yakachena, yakafanana, uye inonamira zvakanaka, uye "inosimbisa" zvikamu zvesimbi, ichiisa hwaro hwakakwana hwemabasa anotevera akadai sekupfapfaidza, electroplating, uye welding. Mubasa remaindasitiri, tinotenda kuti "hwaro husina kusimba hunotungamira kukusagadzikana." Kugadzirisa uku ndiko "hwaro" hwebasa rese rakanaka. Kushandisa sandblasting ye alumina chena nemazvo kunogona kuita sedanho rekuwedzera mukuita, asi kunochengetedza mari yakawanda pakugadzirisa patsva nekugadzirisa gare gare. Kuchinjana kwakakosha zvisinei nekuti unoiona sei! Zvakafanana ne "mombe yekare" yakanyarara asi yakavimbika zvikuru mukugadzirisa simbi, isingakuodzi mwoyo kana zvichikosha zvikuru.
