Kukuya vhiriimhando yebasa rekucheka, imhando yeabrasive yekucheka maturusi. Muvhiri rekukuya, iyo abrasive ine basa rakafanana nereseration mushizha resaha. Asi kusiyana nebanga remasaha, iro rine mitsara chete kumacheto, abrasive yevhiri rekukuya inogoverwa muvhiri rose. Zviuru zvezvimedu zvakaoma abrasive zvinofambiswa nepakati pebasa kuti zvibvise zvidimbu zvidiki zvezvinhu.
Kazhinji abrasive suppliers vanopa akasiyana ezvigadzirwa zveakasiyana ekukuya maapplication mukugadzira simbi. Kusarudza chigadzirwa chisina kunaka kunogona kutora nguva yakawanda nemari. Iri bepa rinopa mamwe mamisimboti ekusarudza vhiri rekukuya rakanakisa.
Abrasive: rudzi rwejecha
Gumbo rekukuya kana rimwe dombo rekukuya rine zvinhu zviviri zvikuru:
Iwo magrits anonyatso cheka, uye musanganiswa unobata magrits pamwe chete uye unotsigira grits paunenge uchicheka. Chimiro chegumbo rekukuya chinotarirwa nehuwandu hweabrasive, binder uye void pakati pavo.
Iwo chaiwo mabrasives anoshandiswa mugumbo rekukuya anosarudzwa zvinoenderana nemabatiro avanoita neworkpiece material. Iyo yakanaka abrasive ndeye inokwanisa kuramba yakapinza uye isiri nyore kugomara. Kana passivation inotanga, iyo abrasive inoputika kuita mapoinzi matsva. Rudzi rwega rwega rweabrasive rwakasiyana, nekuoma kwakasiyana, kusimba, kuomarara kwekutsemuka uye kupikisa kupikisa.
Alumina ndiyo inonyanya kushandiswa abrasive mukukuya mavhiri.
Inowanzoshandiswa kugaya carbon steel, alloy steel, high speed simbi, malleable cast iron, simbi yakagadzirwa, bhuronzi nesimbi dzakafanana. Kune akawanda akasiyana marudzi ealuminium abrasives, imwe neimwe yakanyatsogadzirwa uye yakasanganiswa kune imwe mhando yekukuya. Imwe neimwe mhando yealumina ine zita rayo: kazhinji musanganiswa wemabhii nenhamba. Aya mazita achasiyana kubva kumugadziri kuenda kune mugadziri.
Zirconia aluminaimwe nhevedzano yeabrasives, yakagadzirwa nekusanganisa alumina uye zirconia muzvikamu zvakasiyana. Musanganiswa uyu unoburitsa yakasimba, yakasimba abrasive inoita zvakanaka mukugaya zvikumbiro, senge mukucheka maoparesheni. Zvakare zvinoshanda kune ese marudzi esimbi uye alloy simbi.
Sezvakaita nealuminium, akatiwandei akasiyana ezirconia alumina anowanikwa.
Silicon carbide imwe abrasive inoshandiswa kukuya grey iron, inotonhora iron, brass, soft bronze nealuminium, pamwe nedombo, rabha nemamwe masimbi asina-ferrous.
Ceramic aluminandiyo yazvino kiyi yekuvandudza mune abrasive process. Iyo yakanyanya kuchena tsanga inogadzirwa ne gel sintering process. Iyi abrasive inogona kutyora micron scale nekumhanya kunodzorwa. Zvakare, zviuru zvezvibodzwa zvitsva zviri kuumba. Ceramic alumina abrasives yakaoma kwazvo uye inoshandiswa mukudiwa chaiko kukuya kwesimbi. Iwo anowanzo kusanganiswa nemamwe mabrasives muzvikamu zvakasiyana kuti awedzere kuita kwavo muzvinhu zvakasiyana uye mashandisirwo.
