Ndezvipi zvikamu zvikuru zvegirazi fiber rods uye girazi fibre rods ye induction kupisa mavira?

Girazi fiber tsvimbo uye girazi fiber tsvimbo (yaimbonzi girazi faibha) ye induction yekupisa choto inorganic isiri-metallic zvinhu zvine mashandiro akanaka. Ine mhando dzakawanda. Mabhenefiti ayo akanaka kuvharisa, kupisa kupisa, kusagadzika kwecorrosion uye yakakwirira mechanical simba. Nekudaro, iyo yakashata yayo ndeye brittleness uye kushomeka kusakara kupfeka. Yakagadzirwa nepyrophyllite, jecha requartz, limestone, dolomite, boron calcite uye brucite sezvinhu zvakasvibirira, zvinonyungudutswa, zvinokweva, ronda uye kurukwa pakupisa kwakanyanya. Yayo monofilament dhayamita akati wandei kusvika kumakumi maviri mamicrons, ayo akaenzana ne1/20-1/5 yebvudzi. Imwe neimwe bundle yefiber precursors ine mazana kana kunyange mazana. Zviuru zve monofilaments. Fiberglass tsvimbo uye fiberglass tsvimbo ye induction heat furnaces inowanzo shandiswa sezvinhu zvekusimbisa mundima dzehupfumi senge zvinhu zvinoumbwa, zvemagetsi insulating zvinhu uye insulating zvinhu, uye matunhu substrates.

Izvo zvakakosha zvegirazi fiber rods uye girazi fiber tsvimbo ye induction yekupisa mavira silika, alumina, calcium oxide, boron oxide, magnesium oxide uye sodium oxide. Zvinoenderana nealkali yemukati yegirazi, inogona kukamurwa kuita alkali-isina girazi faibha (0% -2% sodium oxide, yealuminoborosilicate girazi), yepakati alkali girazi fiber (8% -12% sodium oxide, ye boron- ine kana borosilicate-isina girazi) sodium girazi) uye yakakwirira alkali girazi. Girazi faibha (sodium oxide, inopfuura 13%, sodium silicate girazi).
