sulfure wakuda ntchito mosamala

sulfure wakuda 240%ndi mamolekyu apamwamba omwe ali ndi sulfure yambiri, kapangidwe kake kamakhala ndi zomangira za disulfide ndi zomangira za polysulfide, ndipo ndizosakhazikika. Makamaka, chomangira polysulfide akhoza oxidized kuti sulfure okusayidi ndi mpweya mu mlengalenga pansi zina kutentha ndi chinyezi zinthu, ndi zina kucheza ndi mamolekyu madzi mu mpweya kupanga sulfuric acid, motero kuchepetsa mphamvu ya ulusi, CHIKWANGWANI brittleness, ndi ulusi onse ndi embrittle mu ufa pamene kwambiri. Pazifukwa izi, pofuna kuchepetsa kapena kupewa kuwonongeka kwa fiber brittleness pambuyo popaka utoto wakuda wakuda, mfundo zotsatirazi ziyenera kudziwika:

① Kuchuluka kwa utoto wakuda wonyezimira kuyenera kukhala kochepa, ndipo kuchuluka kwa utoto wapadera wa mercerized sayenera kupitirira 700g/ phukusi. Chifukwa cha kuchuluka kwa utoto, mwayi wa brittleness ndi waukulu, ndipo kufulumira kwa utoto kumachepetsedwa, ndipo kuchapa kumakhala kovuta kwambiri.

② Pambuyo popaka utoto, iyenera kutsukidwa mokwanira kuti isatsukidwe kodetsedwa, ndipo utoto woyandama pa ulusiwu ndi wosavuta kuwola kukhala sulfuric acid pakusungidwa, zomwe zimapangitsa kuti ulusiwo ukhale wolimba.

③ Pambuyo popaka utoto, urea, phulusa la koloko ndi sodium acetate ziyenera kugwiritsidwa ntchito polimbana ndi brittleness.

④ Ulusi umawiritsidwa m'madzi oyera musanadayidwe, ndipo kuchuluka kwa ulusi wopaka m'madzi oyera ndikwabwino kuposa sopo mukadaya.

⑤ Ulusi uyenera kuumitsidwa pakapita nthawi mutatha utoto, chifukwa ulusi wonyowa ndi wosavuta kutentha mu mulu, kuti zomwe zili mu ulusi wotsutsa-brittleness zichepetse, mtengo wa pH umachepetsedwa, zomwe sizikugwirizana ndi anti-brittleness. Mukatha kuyanika ulusiwo, uyenera kuziziritsidwa mwachibadwa, kuti kutentha kwa ulusi kumangiridwe kusanagwe kutentha. Chifukwa sichimakhazikika mutatha kuyanika ndikudzaza nthawi yomweyo, kutentha sikophweka kugawira, zomwe zimawonjezera mphamvu zowonongeka kwa utoto ndi asidi, zomwe zimapangitsa kuti fiber ikhale yovuta.

⑥Kusankhidwa kwa utoto wakuda wa brittle-sulphur, utoto wotere wawonjezedwa ku formaldehyde ndi chloroacetic acid popanga, zomwe zimachititsa kuti methyl-chlorine vulcanized anti-brittle-black, kuti maatomu a sulfure osungunula mosavuta akhale okhazikika, omwe amatha kuletsa ma oxidation a sulfure.
