Zvigadzirwa
Brown fused alumina grit ye sandpaper grind vhiri rakafukidzwa abrasive
Brown fused alumina/brown corundum, inozivikanwa seemery, ibrown artificial corundum inogadzirwa nekunyungudutsa nekuderedza zvinhu zvitatu: bauxite, carbon material uye iron filings mu electric arc furnace, ndosaka zita racho richinzi. Chinhu chikuru chayo ialumina, uye magiredhi anosiyaniswawo nehuwandu hwearuminiyamu. Kana aruminiyamu yakaderera, kuoma kwayo kunoderedza. Hukuru hwezvinhu zvakagadzirwa hunogadzirwa zvinoenderana nemazinga epasi rose uye zviyero zvenyika, uye hunogona kugadziriswa zvinoenderana nezvinodiwa nevashandisi. Hukuru hwezvinhu zvacho iF4~F320, uye makemikari ayo anosiyana zvichienderana nehukuru hwezvinhu. Chinhu chinoshamisa ndechekuti saizi yekristaro idiki uye haikanganisike. Nekuti inogadziriswa uye inoputswa nemuchina unozvigaya wega, zvikamu zvacho zvinonyanya kunge zviri denderedzwa. Pamusoro payo pakaoma uye pakachena, uye zviri nyore kubatana nebinder. Brown fused alumina yakagadzirwa neabrasive grade bauxite sezvinhu zvisina kugadzirwa uye inowedzerwa nezvinhu zvinobatsira. Inonatswa mu electric arc furnace pakupisa kwakanyanya pamusoro pe2250℃. Pachikonzero ichi, inonatswa nechinhu chinoparadzanisa magineti chine simba guru uye kusimba kwayo kuri pamusoro pe1850℃. Corundum yebrown inogadzirwa nekambani yedu ine hunhu hwekuchena kwakanyanya, crystallization yakanaka, fluidity yakasimba, low linear expansion coefficient uye corrosion resistance. Chigadzirwa ichi chine hunhu hwekusaputika, kusaita upfu, uye kusatsemuka panguva yekushandiswa, uye chinowanzoshandiswa mumaindasitiri eabrasives uye refractory raw materials.

Zvinhu zvekushandisa zvinobvisa maburi: Vhiri rekukuya, bhandi rekukwesha, sandpaper, jira rekukwesha, chidimbu chekucheka, tekinoroji yekuputisa jecha, kukwesha, pasi risingaparare, kucheka mvura nejeti, zvinobvisa maburi zvakaputirwa, zvinobvisa maburi zvakasanganiswa, nezvimwewo.
Zvinhu zvinoramba kurira: Zvinogona kurira, zvidhinha zvinoramba kurira, zvinhu zvinomira, ndiro inotsvedza, nozzle, ladle, zvinhu zve lining. kukanda nemazvo, nezvimwewo
Korundum yebrown inonzi mazino eindasitiri: inonyanya kushandiswa muzvinhu zvinodzivirira ganda, mavhiri ekukuya, uye jecha rinoputika.
1. Inoshandiswa kugadzira zvinhu zvepamusoro zvinoramba kurira, zvinhu zvinokandwa, zvidhinha zvinoramba kurira, nezvimwewo.
2. Kuputira jecha—chinhu chinoputika chine kuoma kuri pakati nepakati, kurema kwakanyanya, hachina silica yakasununguka, simba guru remagetsi, uye kusimba kwakanaka. Chinhu chakakodzera che "kuchengetedza nharaunda" chekuputika jecha. Chinoshandiswa zvakanyanya mukugadzira ma profiles ealuminium, ma profiles emhangura, magirazi, uye majini akagezwa. Zviumbwa zvemhando yepamusoro nedzimwe nzvimbo;
3. Inokwesha kugaya-kukuya giredhi remahara, inoiswa pakukuya kusununguka muminda yepicture tube, optical glass, monocrystalline silicon, lens, watch glass, crystal glass, jade, nezvimwewo. Ichinhu chekukuya chepamusoro-soro chinowanzoshandiswa muChina;
4. Resin Abrasives-Abrasives ine ruvara rwakakodzera, kuomarara kwakanaka, kuomarara, mhando yakakodzera yezvikamu zvechikamu uye kuchengetedza mupendero, inoiswa kune resin abrasives, mhedzisiro yacho yakanaka;
5. Zvinhu zvinobvisa ruvara zvakaputirwa—zvinhu zvinobvisa ruvara zvinoshandiswa nevagadziri vakaita sesandpaper negauze;
6. Kuzadza kunoshanda - kunonyanya kushandiswa pazvikamu zvemabhureki emotokari, matai akakosha, zvigadzirwa zvekuvaka zvakakosha uye mamwe makorari, ayo anogona kushandiswa sezvinhu zvisingapfeki senge nzira dzendege, madoko, nzvimbo dzekupaka mota, pasi pemaindasitiri, nzvimbo dzemitambo, nezvimwewo;
7. Sefa media - nzvimbo itsva yekushandisa mabrasives. Magrainular abrasives anoshandiswa senzvimbo yepasi pesefa yekuchenesa mvura yekunwa kana mvura yakasviba. Imhando itsva yezvinhu zvekusefa mvura kumba nekune dzimwe nyika, zvinonyanya kukodzera kugadzirwa kwesimbi isina ferrous mineral: oil drilling mud weighting agent:
8. Kucheka ne hydraulic - kunoshandisa ma abrasives senzira yekucheka uye kunoshandisa majeti emvura ane simba guru pakucheka zvinhu zvishoma. Kunoshandiswa pakucheka mapaipi emafuta (gasi rechisikigo), simbi nezvimwe zvikamu. Inzira itsva, ine hushamwari kune zvakatipoteredza uye yakachengeteka yekucheka.
