Mica Flakes Kuchinja Indasitiri yeRabha Gwaro Rakazara reVanozadza Zvishandiso Zvikuru

Tsananguro pfupi:

Maflakes eMica, ane chimiro chayo chakasiyana chelamellar, kugadzikana kwemakemikari kwakanyanya, uye kuenderana kunoshamisa nemamatrices erabha, akazviratidza semafiller anoshanda zvakanyanya muindasitiri yerabha. Kusiyana nemafillers echinyakare akadai secarbon black kana calcium carbonate, maflakes emica anopa musanganiswa wakasiyana wekusimbisa michina, kuramba mamiriro ekunze, uye kugadzikana kwehukuru, zvichiita kuti ave sarudzo yakakodzera yezvigadzirwa zverabha zvinoshanda munzvimbo dzakaoma, kusanganisira zvisimbiso zvemotokari, mapombi erabha emaindasitiri, uye mabhandi ekufambisa.

Munzvimbo yezvisimbiso zverabha zvemotokari, zvinosanganisira zvisimbiso zvemasuo, zvisimbiso zvemahwindo, uye magasket einjini, mica flakes inoita basa guru mukuwedzera kudzivirira kubvaruka uye kushanda zvakanaka kweseti yekumanikidzwa. Zvisimbiso izvi zvinowanzosangana nekumanikidzwa kwemuchina, kuchinja-chinja kwekupisa kwakanyanya kubva -40°C kusvika 120°C, uye kugara uchisangana nemwaranzi yeUV kwenguva refu, zvinhu zvinogona kukonzera kuti zvisimbiso zverabha zvitsemuke, zviome, kana kuti zvirase kusimba nekufamba kwenguva.

Kuwedzerwa kwe8%-15% yema "high aspect ratio mica flakes", ane saizi ye "particle size" ye30-80 μm uye "aspect ratio" ye ≥100, kune rabha ye ethylene-propylene-diene monomer (EPDM) kunoburitsa mhedzisiro inoshamisa. Simba rekubvaruka kwerabha rinowedzera ne40%-60%, nepo "compression set rate", yakayerwa mushure memaawa makumi manomwe pa100°C, inoderera zvakanyanya kubva pa35% kusvika pa15%. Mugadziri wezvikamu zvemotokari anotungamira muGermany akaita bvunzo dzakakura achishandisa ma "mica flakes" edu mu "EPDM door seals". Mhedzisiro yacho yaive inoshamisa: ma "seals" akaramba achichinjika uye achisimbisa mashandiro awo kwe500,000 cycles dzekuvhura nekuvhara, zvichienzaniswa ne300,000 cycles dze "seals" dzisina ma "mica flakes". Hupenyu hwebasa uhwu hwakareba haungoderedzi mari yekugadzirisa yevaridzi vemotokari chete asiwo hunosimudzira kuvimbika kwezvigadzirwa zvemotokari.

Pamapombi erabha emuindasitiri anoshandiswa mukutamisa makemikari, mafuta, nemvura, ma mica flakes anobatsira mukuwedzera kuramba kwemakemikari uye kuramba kumanikidzwa. Mapombi aya anowanzo sangana nezvinoparadza uye anofanira kutsungirira kumanikidzwa kwakanyanya kwemukati kusvika ku10 MPa. Ma Mica flakes, ane chimiro chayo che lamellar chisingapindi mvura, anoumba chipingamupinyi chinoshanda mukati me rabha matrix, zvichideredza kupinda kwemakemikari ne50%-70%.

Kana ikaiswa mumapaipi erabha e nitrile (NBR) pachiyero che10%-20%, ma mica flakes anowedzera zvakanyanya kumanikidzwa kwepaipi ne25%-35% uye inowedzera hupenyu hwayo hwekushanda mukushandiswa kwemafuta kubva pagore rimwe kusvika kumakore maviri-matatu. Imwe fekitori yemakemikari muNetherlands yakaedza mapaipi edu eNBR akasimbiswa ne mica mukutamiswa kwe20% sulfuric acid. Mhedzisiro yacho yaive yechokwadi: mushure memwedzi gumi nemiviri yekushandiswa nguva dzose, mapaipi haana kuratidza zviratidzo zvekuzvimba kana kubuda kwemvura, nepo mapaipi eNBR akajairwa akakundikana mushure memwedzi mina chete. Pamusoro pezvo, ma mica flakes anovandudza kugadzikana kwemapaipi erabha, achideredza kudzikira panguva ye vulcanization ne15%-25% uye achivimbisa kukodzera kwakakodzera nema connectors.

Magirazi edu ese emumica anosangana nezvinodiwa zvakanyanya muindasitiri maererano nezviratidzo zvikuru zvehunyanzvi. Hunyoro hwemvura huri ≤0.3%, hunyoro hwedota huri ≤0.5%, hunyoro hwemafuta huri ≤25 mL/100g, uye hunodzivirira kupisa zvakanyanya, hunoramba hwakagadzikana patembiricha inosvika 600°C. Uyezve, zvigadzirwa zvedu zvinoenderana zvizere nemitemo yeRoHS neREACH, nehuwandu hwesimbi inorema huri pasi pemiganhu yekuchengetedza yepasi rose (lead iri ≤0.0005%, arsenic iri ≤0.0003%).

Kana zvasvika pakugadzira zvinhu, tinokoshesa kunaka uye kusimba kwezvigadzirwa zvedu. Ma "mica flakes" edu akaiswa mumabhegi asinganyungudike (25 kg/bhegi), aine firimu remukati re polyethylene uye bhegi rekunze re kraft paper kudzivirira kunyungudika kwemvura panguva yekufambisa mugungwa. Takasimbisa hukama hwakasimba nemakambani makuru ekutakura zvinhu akadai seMaersk neCOSCO, tichiona kuti vatengi vedu vari muEurope, North America, neSoutheast Asia vanosvika nenguva mukati memazuva gumi nemashanu kusvika makumi matatu.

Ruzivo rweChigadzirwa

Matagi eChigadzirwa

Mica izita remaminerari eboka remica. Ndiyo aluminosilicate yepotassium, aruminiyamu, magnesium, iron, lithium nedzimwe simbi, dzese dzakaiswa layers uye monoclinic. Kristaro yakaita se pseudohexagonal lamellae kana plate like, dzimwe nguva columnar. Lamellar cleavage yakakwana, ine girazi rinopenya uye elastic sheet. Refractive index ye mica inowedzera nekuwedzera kwe iron content, kubva pa low protrusion kusvika pa medium protrusion. Mhando isina iron haina ruvara mu flake. Kana iron content yakakwira, ruvara rwakasviba, uye polychromatic uye inonyungudutsa.

Saizi yeMica flake: 6-10mesh, 10-20mesh,
Upfu hweMica: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh uye 5000mesh.

Kushandiswa
Muindasitiri, biotite inonyanya kushandisa insulation yayo uye kudzivirira kupisa, pamwe nekudzivirira acid, alkali, compression resistance uye peeling, sezvinhu zvinodzivirira zvemidziyo yemagetsi nemidziyo yemagetsi; chechipiri, inoshandiswa kugadzira mahwindo nezvikamu zvemakanika zvemaboiler esteam nemidziyo yekunyungudutsa. Mica chips ne mica powder zvinogona kugadzirwa kuita mica paper, uye zvinogonawo kutsiva mica sheet kugadzira zvinhu zvakasiyana-siyana zvinodzivirira kupisa zvine mutengo wakaderera uye zvakaenzana.

Muscovite ndiyo inonyanya kushandiswa mumaindasitiri, ichiteverwa nephlogopite. Inoshandiswa zvakanyanya mumaindasitiri ezvishandiso zvekuvaka, maindasitiri ekudzimisa moto, chinodzima moto, welding rod, purasitiki, electrical insulation, kugadzira mapepa, asphalt paper, rabha, pearlescent pigment nemamwe maindasitiri emakemikari.

Upfu hwemica hwakatsetseka hunoshandiswa sechinozadza chinoshanda chepurasitiki, pendi, pendi, rabha nezvimwewo, izvo zvinogona kuvandudza simba rayo remuchina, kuwedzera kusimba, kunamira, kudzivirira kukwegura uye kuramba ngura.
