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 mpweya zina kutentha ndi chinyezi zinthu, ndi zina kucheza ndi mamolekyu madzi mlengalenga kupanga sulfuric acid, motero kuchepetsa mphamvu ya ulusi, CHIKWANGWANI brittleness, ndi ulusi onse ndi embrittle kukhala ufa pamene kwambiri.Pazifukwa izi, kuti muchepetse kapena kupewa kuwonongeka kwa fiber brittleness mutapaka utoto wakuda wakuda, mfundo zotsatirazi ziyenera kudziwika:

① Kuchuluka kwa utoto wakuda wonyezimira kuyenera kukhala kochepa, ndipo kuchuluka kwa utoto wapadera wa mercerized sikuyenera 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 ulusi 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 Ulusiwo umawiritsidwa m'madzi oyera musanadayidwe, ndipo kuchuluka kwa ulusi wopaka m'madzi oyera ndikwabwino kuposa sopo mutapaka utoto.

⑤ Ulusi uyenera kuumitsidwa pakapita nthawi mutatha utoto, chifukwa ulusi wonyowa ndi wosavuta kutentha mu mulu, kotero kuti zomwe zili mu ulusi wotsutsa-brittleness zimachepetsa, pH mtengo umachepetsedwa, zomwe sizingathandize kutsutsa- brittleness.Mukatha kuyanika ulusiwo, uyenera kuziziritsidwa mwachibadwa, kuti kutentha kwa ulusi kumangiridwe kusanagwe kutentha.Chifukwa sichimazizira pambuyo poyanika ndipo nthawi yomweyo imadzaza, kutentha sikophweka kugawira, zomwe zimawonjezera mphamvu zowonongeka kwa utoto ndi asidi, zomwe zimapangitsa kuti ulusi ukhale wonyezimira.

⑥Kusankhidwa kwa utoto wakuda wa anti-brittle-sulphur, utoto wotere wawonjezedwa ku formaldehyde ndi chloroacetic acid popanga, zotsatira zake za methyl-chlorine vulcanized anti-brittle-black, kuti maatomu a sulfure oxidized mosavuta akhale okhazikika, omwe imatha kuletsa makutidwe ndi okosijeni a maatomu a sulfure kupanga asidi ndi chimfine chophwanyika.
