Zvipfeko zveDenim zvakadhayiwa neSulfur Nhema BR zvine mukurumbira.Midziyo yekudhaya yatinoshandisa inotora nzira yekuenderera mberi nekudhinda uye kudhayiwa kwewarp shaft, uye maitiro ekugadzira anenge akakura.Sulfur Black BR haina kunyungudika mumvura, asi, inogona kunyungudutswa mune sodium sulfide mhinduro nekudzokera kune yakavanzika ruvara.Uyu muviri wakavanzika weruvara unogona kudhayiwa pa cellulose fiber kuti upedze kudhaya.Izvo zvinhu zvesarufa dhayi zvakafanana neaya akananga dhayi uye vat dhayi.Iyo reductant yeSulfur Black BR, sodium sulfide, ine kushaya simba, saka hazvisi nyore kuti sulfur dema ideredzwe.Panguva imwecheteyo, iyo Sulfur Black BR yakagadzikana pane yakanyanya kupisa.Kana iyo Sulfur Black BR dhayi ikaderedzwa uye yakanyungudika nesodium sulfide, inogadzira thiophenol, inoshandurwa kuita sodium sulfide uye yakanyungudika.
Mushonga wedhayi unoumbwa nesarufa dhayi yakaderedzwa nesodium sulfide haina kugadzikana zvakakwana.Iyo Sulfur Black BR dhayi inongoda kugezwa zvizere kuti ibvise yasara sodium sulfide pamucheka uye inogona kuzara oxidized nemhepo.Huwandu hwesodium sulfide inoshandiswa kudzorera nekunyungudutsa Sulfur Black BR haigone kuverengerwa nemazvo.
Mushure mekudhaya dhayi neSulfur Nhema BR dhayi, inofanirwa kuve yakasanganiswa neoxidized kuti iite isinganyunguke dhayi uye yakagadzika pane fiber.sulfur dema inogona kuve yakasvibiswa chero bedzi ichigezwa uye ichifefeterwa.Kana uchidhayiwa nedhayi nekukurumidza oxidation rate ye leuco compound, kana dhayi ikaratidzwa kumhepo kana sodium sulfide isina kukwana, inozoiswa oxidized nguva isati yakwana kuti ibudise tsvina.Dhayi kunze kwesarufa dema inogona kurapwa nekugadzirisa agent kuvandudza kukurumidza kwemavara.Copper sulfate inogona kukonzeresa brittle fiber yeSulfur Black BR, saka copper sulfate haigone kushandiswa kugadzirisa.
