Upfu hwesilica hunogadzirwa nequartz yechisikigo (SiO2) kana fused quartz (amorphous SiO2 mushure mekunge quartz yechisikigo yanyungudika uye yatonhodzwa pakupisa kwakanyanya) kuburikidza nekupwanya, kukuya, kutenderera, kuchenesa neacid washing, kurapwa nemvura yakachena zvakanyanya uye mamwe maitiro. Saka chii chinonzi mashandiro uye maitiro ekugadzira silicon powder? Zvinotevera zvinotsanangura mashandiro esilicon powder uye maitiro ekugadzirasiliconchigayo chekukuya cheupfu.

Pamusoro pekuwedzera kwemafuta ekupisa kwakaderera, hunhu hwakanaka hwe dielectric, kufambisa kwemafuta zvakanyanya, kushanda zvakanaka kwekumisa uye zvimwe hunhu hwakanaka, hunhu hwe silica powder hunosanganisirawo zvinotevera:

(1) Kudzivirira kwakanaka: nekuda kwekuchena kwakanyanya kweupfu hwesilicon, huwandu husina kuchena, kushanda kwakasimba uye kudzivirira kwakanaka kwemagetsi, chigadzirwa chakaporeswa chine kudzivirira kwakanaka uye kuramba arc.

(2) Inogona kuderedza tembiricha yepamusoro-soro ye epoxy resin curing reaction, kuderedza linear expansion coefficient uye shrinkage rate yechigadzirwa chakaporeswa, nokudaro ichibvisa kushushikana kwemukati kwechigadzirwa chakaporeswa uye kudzivirira kutsemuka.

(3) Kuramba ngura: upfu hwesilica hausi nyore kusanganiswa nezvimwe zvinhu, uye hauna makemikari anokonzerwa nemaacids akawanda nealkalis. Zvidimbu zvayo zvakafukidzwa zvakaenzana pamusoro pechinhu chacho, zvine ngura yakasimba.

(4) Kuyera zvidimbu zvechinhu kwakaringana, izvo zvinogona kuderedza uye kubvisa kudonha kwevhu uye kuumbwa kwezvikamu kana zvikashandiswa; Zvinogona kuwedzera simba rekumanikidza uye kudzvanya kwechigadzirwa chabviswa, kuvandudza kuramba kwekupfekwa, kuwedzera kupisa kwechigadzirwa chabviswa, uye kuwedzera kunonoka kwemoto.

(5) Upfu hwesilica hwakagadziriswa ne silane coupling agent hunokwanisa kunyorova zvakanaka kuma resin akasiyana-siyana, hunoshanda zvakanaka pakunyungudutsa, huri nyore kusanganisa uye hahusanganisike.

(6) Kuwedzerwa kweupfu hwesilica sechinozadza mu organic resin hakungogadzirisi chete hunhu hwechigadzirwa chakacheneswa, asi kunoderedzawo mutengo wechigadzirwa.

Maitiro ekugadzira silica powder anosanganisira kukuya kwakaoma uye kukuya kwakanyorova.

Maitiro ekugadzira upfu hwesilicon yakapwanyika: isa zvinhu zvakasvinwa zvesilicon powder musiliconsimbikukuyachigayomuchinayekukuya. Maitiro ekukuya anogona kuramba achipa nekuburitsa zvinhu zvinorema panguva imwe chete, uye ozoburitsa zvinhu mushure mekukuya nguva nenguva kakawanda; Pakuburitsa zvinhu, saizi yezvikamu inofanira kudzorwa nemuchina wekuisa hupfu hwakatsetseka. Zvigadzirwa zvakaoma zvinofanira kudzoserwa kuchigayo kuti zvikuyiwezve kana sezvigadzirwa, uye zvigadzirwa zvakanaka zvinofanira kuva zvigadzirwa. Pakukuya kwakaoma, dzorai hunyoro hwezvinhu zvekukuya, uye chigadzirwa hachizoome.

Maitiro ekugadzira upfu hwesilica hwekukuya hwakanyorova: isa zvinhu zvakawanda zveupfu hwesilica mugomba rebhora panguva imwe chete, wedzera huwandu hwakakodzera hwemvura, uye huwandu hwekushanda hunosvika 65% ~ 80%; Mushure mekukuya nguva dzose kwemaawa anopfuura gumi, dururira slurry, shandisa nzira yekusefa pressure kana kuiisa mubharero rezvinhu kuti iite mvura uye iome, uye uwane keke rezvinhu zvine mvura; Mushure mekupwanywa uye kuparadzirwa ne crusher, inoiswa zvakaenzana uye inoramba ichiiswa mugomba rakavhurika rinosanganisa dryer, uye chigadzirwa chinowanikwa mushure mekuomeswa.

Mukugadzirwa kweupfu hwesilicon hwakaomeswa, nyanzvi yekukuya upfu hwesilicon inogona kusarudzwa.HLMXupfu hwesilicon yakatwasuka zvakanyanyakukuyachigayoYakagadzirwa neHCMilling (Guilin Hongcheng) inogona kuita basa guru mukugadzirwa kweupfu hwesilicon hwakaomeswa. Nekuda kwekushanda kwayo kwepamusoro, kunyatsorongeka kwayo uye mhando yepamusoro yezvigadzirwa zvekukuya, yakawana rumbidzo kubva kuvatengi, uye yakakodzera kwazvo semuchina wekugadzira.kugadzirwa kweupfu hwesiliconmutsetsemidziyo.

Semugadziri ane ruzivo rwekugadzira michina yekuchera nemidziyo, HCMilling (Guilin Hongcheng) inyanzvi mukugadzira mhando dzakasiyana dzemichina yekuchera migodhi.kukuya kweupfu hwesiliconchigayomichina. Kana muchida kuziva zvakawanda nezvemaitiro ekugadzira upfu hwesilicon, ndapota bvunzai HCM kuti muwane rumwe ruzivo.
