Kodi Mumadziwa Chiyani Zokhudza Utoto Wa Sulfure(2)?

mtundu

Mitundu yayikulu ya utoto wa sulfure ndi wakuda wa sulfure (CI sulfure wakuda 1). Amakonzedwa ndi hydrolyzing 2, 4-dinitrochlorobenzene ndi sodium hydroxide solution mu sodium dinitrophenol solution pafupi ndi kuwira, ndiyeno kutentha ndi kuwira ndi sodium polysulfide solution pamlingo wina wa maselo, ndi kuchepetsa ndi sulfurizing anachita mopanikizika kapena popanda kukakamizidwa. Pambuyo pomaliza sulfure, amawumitsidwa mwachindunji ndi chowumitsira kuti apeze utoto woyambirira. Kenako amasakanikirana ndi utoto wamalonda. Pa vulcanization, kuchuluka kwa maselo a sodium phenol ndi sodium polysulfide, x (ie, sulfure index) mu sodium polysulfide Na2Sx ndi kutentha komwe kumasiyanasiyana, kotero kuti kuwala kwamtundu wa sulfure wakuda kumakhala ndi kusiyana kwa kuwala kobiriwira, wobiriwira. kuwala kofiira ndi kuwala kofiira. Choyipa chachikulu cha utoto wakuda wa sulfure ndi chodabwitsa cha brittle cloth. Izi ndichifukwa choti molekyulu yakuda ya sulfide imakhala ndi sulfure yogwira ntchito ngati maunyolo a polysulfide. Kapangidwe ka sulufule kameneka kamakhala kosakhazikika, ndipo utoto ukatenthedwa kapena kuikidwa mumpweya wotentha ndi wonyowa, umakhala wosavuta kuti oxidize kukhala sulfuric acid, zomwe zimapangitsa kuti nsalu ya thonje ikhale yolimba. M'zaka zaposachedwa, pokonza njira yopangira sulfure wakuda, sulfure wamba wakuda umakhazikika mpaka pafupifupi 100 ℃ atapangidwa, ndipo formaldehyde ndi monochloroacetic acid amawonjezeredwa kuti akhazikitse sulfure wosakhazikika mu utoto, ndi anti-brittle sulfure wakuda. kudaya kumapangidwa.

Gwiritsani ntchito

Utoto wa sulfure umagwiritsidwa ntchito kuchepetsedwa kukhala leucosome yosungunuka m'madzi ndi sodium sulfide kapena ufa wa inshuwaransi, kenako kusinthidwa ku chinthu choyambirira chosasunthika chamitundu itatha kuyamwa ndi utoto kudzera mu oxidation kapena zotsatira zina, kuti utoto ukhazikike pa utoto. .

Ikani

Utoto wa sulfure umagwiritsidwa ntchito kwambiri popaka utoto wa ulusi wa cellulose, womwe umagwiritsidwa ntchito makamaka mu ulusi, mawonekedwe ndi nsalu zina zamakampani ndi nsalu zolemera. Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi Sulfur Yuan, sulfure blue,

Njira yochepetsera

(1) Katundu wa othandizira kuchepetsa

1. Katundu wa Na2S

(1) Amatchedwanso alkali sulfide, dzina lodziwika bwino la alkali lonunkhira, kapangidwe kake ka sulfide yamafakitale imakhala pafupifupi 50%, ndipo mawonekedwe ake ndi olimba. Ndiwochepetsera, komanso ndi alkali wamphamvu, katundu wokhazikika. Kuchepetsa mphamvu ya sodium sulfide ndi yotsika kuposa ya ufa wa inshuwaransi, alkalinity ndi yotsika kuposa caustic soda komanso wamkulu kuposa phulusa la soda, ndipo imakhala ndi dzimbiri lamphamvu pakhungu.

(2) Sodium sulfide hydrolysis kwa NaHS, NaHS pa kuchepetsa utoto, tingaone kuti sodium sulfide kuchepetsa mphamvu zikugwirizana ndi hydrolysis ake.

(3) Sodium sulfide imatulutsa mpweya wa H2S ikakumana ndi asidi, choncho samalani kuti musaikidwe pamodzi ndi asidi.

(4) Kuwonekera kwa sodium sulfide mu mlengalenga kudzayamwa madzi, C02, 02, etc., kotero kuti mapangidwe ogwira mtima amachepetsa ndipo pang'onopang'ono amalephera. Choncho, iyenera kusindikizidwa ikasungidwa, ndipo mawonekedwe ake ayenera kufufuzidwa ngati sagwiritsidwanso ntchito kwa nthawi yaitali.

(5) Njira yothetsera sodium sulfide siyenera kukhala yayitali, apo ayi idzakhala oxidized ndi mpweya ndikuchepetsa mphamvu yake.

ntchito

Amagwiritsidwa ntchito makamaka pa thonje, hemp fiber dyeing

Kampani yathu imapanga makamakaSulfur Black Bluish,Sulfur Blue Brn 150%,Sulfur Red 14,Mitundu Yofiira ya Sulfurndi mitundu ina yambiri ya sulfure, yomwe imagulitsidwa kunyumba ndi kunja, monga Bangladesh, Pakistan, Turkey, India, Vietnam, Italy, etc. ubwino wamtengo. Tikuthokozanso makasitomala athu chifukwa chothandizira komanso kuzindikira kampani yathu.
