Malangizo ogwiritsira ntchito sulfure wakuda

sulfure wakuda 240%Ndi chinthu chokhala ndi mamolekyu ambiri chokhala ndi sulfure yambiri, kapangidwe kake kali ndi ma disulfide bonds ndi ma polysulfide bonds, ndipo sichikhazikika kwambiri. Makamaka, polysulfide bond imatha kusinthidwa kukhala sulfure oxide ndi mpweya mumlengalenga pansi pa kutentha ndi chinyezi, ndikulumikizananso ndi mamolekyu amadzi mumlengalenga kuti apange sulfuric acid, motero kuchepetsa mphamvu ya ulusi, kufooka kwa ulusi, ndipo ulusi wonse umasanduka ufa ukakhala woopsa. Pachifukwa ichi, kuti muchepetse kapena kuletsa kuwonongeka kwa ulusi mutapaka utoto ndi utoto wakuda wokhuthala, mfundo zotsatirazi ziyenera kukumbukiridwa:

① Kuchuluka kwa utoto wakuda wopangidwa ndi vulcanized kuyenera kukhala kochepa, ndipo kuchuluka kwa utoto wapadera wa mercerized kuyenera kusapitirira 700g pa paketi. Chifukwa kuchuluka kwa utoto ndi kwakukulu, mwayi woti utotowo ukhale wofooka ndi waukulu, ndipo kulimba kwa utoto kumachepa, ndipo kutsuka kumakhala kovuta.

② Mukapaka utoto, uyenera kutsukidwa bwino kuti usatsukidwe mosayenera, ndipo utoto woyandama pa ulusiwo umatha kuwola mosavuta kukhala sulfuric acid panthawi yosungira, zomwe zimapangitsa kuti ulusiwo ukhale wosweka.

③ Pambuyo popaka utoto, urea, soda ash ndi sodium acetate ziyenera kugwiritsidwa ntchito pochiza kuuma kwa khungu.

④ Ulusi umaphikidwa m'madzi oyera usanapakidwe utoto, ndipo ulusi wopaka utoto m'madzi oyera ndi wabwino kuposa ulusi wa lye ukapakidwa utoto.

⑤ Ulusi uyenera kuumitsidwa nthawi yake utatha kuupaka utoto, chifukwa ulusi wonyowa ndi wosavuta kuutentha mu ndondomeko ya mulu, kotero kuti kuchuluka kwa ulusi woletsa kuphulika kuchepe, pH imachepa, zomwe sizingathandize kuti ulusi uwonongeke. Ulusi ukauma, uyenera kuziziritsidwa mwachilengedwe, kuti kutentha kwa ulusi kukhazikike bwino usanagwere kutentha kwa chipinda. Chifukwa suzizira utatha kuumitsa ndipo nthawi yomweyo umapakidwa, kutentha sikophweka kufalitsa, zomwe zimawonjezera mphamvu ya utoto ndi asidi, zomwe zimapangitsa kuti ulusi ukhale wosweka.

⑥Posankha utoto wakuda wotsutsana ndi brittle-sulfure, utoto woterewu wawonjezedwa ku formaldehyde ndi chloroacetic acid popanga, methyl-chlorine yomwe imayambitsa vulcanized anti-brittle-black, kotero kuti maatomu a sulfure omwe amasungunuka mosavuta amakhala olimba, zomwe zingalepheretse maatomu a sulfure kuti atulutse asidi ndi ulusi wosweka.
