Chifukwa chiyani ulusi umakhala wonyezimira utapaka utoto wa Sulfur Black? Kodi ndingapewe bwanji? Kodi tiyenera kulabadira chiyani pamenepa?

Chifukwa chiyani ulusi wopota umakhala wophulika pambuyo pakeSulfur Black Br kupaka utoto? Kodi ndingapewe bwanji? Kodi tiyenera kulabadira chiyani pamenepa?

Utoto wakuda wa sulfide ndi mamolekyu apamwamba kwambiri okhala ndi sulfure yambiri, kapangidwe kake kamakhala ndi zomangira za disulfide ndi zomangira za polysulfide, ndipo ndi yosakhazikika. Makamaka, chomangira polysulfide akhoza oxidized kuti sulfure okusayidi ndi mpweya mu mpweya zina kutentha ndi chinyezi zinthu, ndi zina kucheza ndi mamolekyu madzi mlengalenga kupanga sulfuric acid, motero kuchepetsa mphamvu ya kupota ulusi, CHIKWANGWANI brittleness, ndipo minyewa yonse imasanduka ufa ikavuta kwambiri.

Pachifukwa ichi, pofuna kuchepetsa kapena kupewa CHIKWANGWANI brittleness kuwonongeka pambuyo kupota ulusi ndiSulfur Black Br dye, mfundo zotsatirazi ziyenera kuganiziridwa:①Kuchuluka kwaSulfur Black Br utoto uyenera kukhala wocheperako, ndipo kuchuluka kwa utoto wapadera wa silika sayenera kupitirira 700g/phukusi. Chifukwa kuchuluka kwa utoto kumakhala kwakukulu, mwayi wa brittleness ndi waukulu, ndipo kufulumira kwa utoto kumachepetsedwa, ndipo kuchapa kumakhala kovuta kwambiri.②Mtundu uyenera kutsukidwa kwathunthu, osasamba, mtundu woyandama pa mzere wozungulira ulusi umakhala wosavuta kuwola kukhala sulfuric acid posungira ndikupangitsa kuti CHIKWANGWANI chiwonongeke.③Pambuyo popaka utoto, urea, phulusa la soda ndi sodium acetate ziyenera kugwiritsidwa ntchito pochiza brittleness.④Ulusi wopota amauwiritsa m’madzi oyera asanapendeke, ndipo kupendekera kwa ulusi wopota ukayesedwa ndi wabwino kuposa ulusi wowiritsa wa lye.⑤Ulusi wopota uyenera kuumitsidwa pakapita nthawi mutatha utoto, chifukwa ulusi wonyowa umangotenthedwa panthawi ya stacking, zomwe zimachepetsa zomwe zili ndi anti-brittleness agent ndi pH mtengo wa ulusi wopota, umene suli wabwino ku anti-brittleness.

Akaumitsa, ulusi wopota uyenera kuzizidwa mwachibadwa, kotero kuti kutentha kwa ulusi wopota ukhoza kupakidwa usanagwe ku kutentha kwa chipinda. Chifukwa sichimazizira pambuyo poyanika ndi kupakidwa nthawi yomweyo, kutentha sikophweka kugawira, zomwe zimawonjezera mphamvu zowonongeka kwa utoto ndi asidi, zomwe zimapangitsa kuti ulusi ukhale wonyezimira.

Kusankhidwa kwa anti-brittle-Sulfur Black Br utoto, utoto wotero wawonjezedwa ku formaldehyde ndi chloroacetic acid popanga, chifukwa chake methyl - chlorine vulcanized anti-brittle-black, kuti maatomu a sulfure okosidwa mosavuta akhale okhazikika, omwe angalepheretse makutidwe ndi okosijeni a maatomu a sulfure kupanga. asidi ndi brittle fiber.
