Kodi Mukudziwa Chiyani Zokhudza Utoto wa Sulphur(2)?

mtundu

Mtundu waukulu wa utoto wa sulfure ndi wakuda wa sulfure (CI sulfure wakuda 1). Umakonzedwa mwa hydrolyzing 2, 4-dinitrochlorobenzene ndi sodium hydroxide solution mu sodium dinitrophenol solution pafupifupi kuwira, kenako kutenthetsa ndi kuwira ndi sodium polysulfide solution pa molecular ratio inayake, ndi kuchepetsa ndi sulfurizing reaction pansi pa kupanikizika kapena palibe kupanikizika. Pambuyo poti sulfurizing reaction yatha, imaumitsidwa mwachindunji ndi chowumitsira kuti ipeze utoto woyambirira. Kenako imasakanizidwa mu utoto wamalonda. Panthawi ya vulcanization, kuchuluka kwa mamolekyu a sodium phenol ndi sodium polysulfide, x(ie, sulfur index) mu sodium polysulfide Na2Sx ndi kutentha kwa reaction zimasiyana, kotero kuti kuwala kwa mtundu wa sulfure wakuda kumakhala ndi kusiyana kwa kuwala kobiriwira, kuwala kofiira kobiriwira ndi kuwala kofiira. Choyipa chachikulu cha utoto wakuda wa sulfure ndi chodabwitsa cha nsalu yofooka. Izi zili choncho chifukwa molekyu wakuda wa sulfure uli ndi active sulfure mu mawonekedwe a polysulfide chains. Kapangidwe ka sulfure aka ndi kosakhazikika, ndipo utoto ukatenthedwa kapena kuyikidwa mumlengalenga wotentha komanso wonyowa, zimakhala zosavuta kusungunuka kukhala sulfuric acid, zomwe zimapangitsa kuti nsalu ya thonje ikhale yopyapyala. M'zaka zaposachedwa, pokonza njira yopangira sulfure wakuda, sulfure wakuda wamba umaziziritsidwa kufika pa 100℃ atapangidwa, ndipo formaldehyde ndi monochloroacetic acid zimawonjezedwa kuti zikhazikitse sulfure wosakhazikika mu utoto, ndipo utoto wakuda wa sulfure wotsutsana ndi brittle umapangidwa.

Gwiritsani ntchito

Utoto wa sulfure umagwiritsidwa ntchito kuchepetsedwa kukhala leucosome yosungunuka m'madzi ndi sodium sulfide kapena ufa woteteza, kenako nkusinthidwa kukhala utoto woyambirira wosasungunuka pambuyo poti utotowo watengedwa kudzera mu okosijeni kapena zotsatira zina, kotero kuti utotowo ukhale pa utotowo.

Ikani

Utoto wa sulfure umagwiritsidwa ntchito kwambiri popaka utoto wa ulusi wa cellulose, makamaka mu ulusi, mawonekedwe ndi nsalu zina zamafakitale ndi nsalu zolemera. Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi sulfure Yuan, sulfure buluu,

Yankho lochepetsa

(1) Kakhalidwe ka zinthu zochepetsera

1. Katundu wa Na2S

(1) Yodziwikanso kuti alkali sulfide, dzina lodziwika bwino la alkali wonunkha, kapangidwe kogwira mtima ka alkali sulfide ya mafakitale nthawi zambiri kamakhala pafupifupi 50%, ndipo mawonekedwe ake ndi olimba achikasu-bulauni. Ndi chinthu chochepetsera, komanso ndi chinthu champhamvu cha alkali, komanso chokhazikika. Mphamvu yochepetsera ya sodium sulfide ndi yotsika kuposa ya ufa woteteza, alkalinity ndi yotsika kuposa caustic soda komanso yoposa soda ash, ndipo imakhala ndi dzimbiri lamphamvu pakhungu.

(2) Kuchuluka kwa sodium sulfide hydrolysis kupita ku NaHS, NaHS pa kuchepetsa utoto, zitha kuwoneka kuti mphamvu yochepetsera sodium sulfide ikugwirizana ndi hydrolysis yake.

(3) Sodium sulfide imapanga mpweya wa H2S ikakumana ndi asidi, choncho muyenera kusamala kuti isaphatikizidwe ndi asidi.

(4) Kupezeka kwa sodium sulfide mumlengalenga kudzayamwa madzi, C02, 02, ndi zina zotero, kotero kuti kapangidwe kogwira ntchito kamachepetsa ndikulephera pang'onopang'ono. Chifukwa chake, kayenera kutsekedwa kakasungidwa, ndipo kapangidwe kake kayenera kufufuzidwa kakagwiritsidwanso ntchito kwa nthawi yayitali.

(5) Sodium sulfide solution siyenera kukhala yayitali, apo ayi idzasungunuka ndi mpweya ndikuchepetsa mphamvu yake.
