Ni iki uzi ku birebana n'irangi rya sulfure (2)?

ubwoko

Ubwoko bw'ingenzi bw'irangi rya sulphur ni umukara wa sulphur (CI sulphur black 1). Ritegurwa hifashishijwe hydrolyzing 2, 4-dinitrochlorobenzene na sodium hydroxide solution mu gisubizo cya sodium dinitrophenol hafi kubira, hanyuma rigashyuha rigashya hamwe na sodium polysulfide solution ku gipimo runaka cya molekile, hanyuma rigagabanya kandi rigahindura sulphur reaction ku gitutu cyangwa nta gitutu. Nyuma y'uko sulphurization reaction irangiye, rirumishwa neza hakoreshejwe icyuma cyuma kugira ngo haboneke irangi ry'umwimerere. Hanyuma rivangwa mu marangi y'ubucuruzi. Mu gihe cyo gushonga, igipimo cya molekile cya sodium phenol na sodium polysulfide, x (ni ukuvuga, sulfur index) muri sodium polysulfide Na2Sx n'ubushyuhe bw'irangi biratandukanye, ku buryo urumuri rw'umukara wa sulphur rugira itandukaniro ry'urumuri rw'icyatsi kibisi, urumuri rw'icyatsi gitukura n'urumuri rutukura. Imbogamizi ikomeye y'irangi ry'umukara wa sulphur ni ikintu cyoroshye gukora. Ibi biterwa nuko molekile y'umukara wa sulphur irimo sulfur ikora mu buryo bwa polysulfide chains. Iyi miterere ya sulfure ntihindagurika, kandi iyo irangi rishyushye cyangwa rishyizwe mu mwuka ushyushye kandi utose, biroroshye kuri ogisijeni rihinduka aside sulfure, bigatuma igitambaro cy'ipamba kidakomera. Mu myaka ya vuba aha, binyuze mu kunoza uburyo bwo gukora umukara wa sulfure, umukara usanzwe wa sulfure ukonjeshwa kugeza kuri 100°C nyuma yo gukorwa, hanyuma formaldehyde na aside monochloroacetic byongerwamo kugira ngo sulfure idahindagurika ihamye iri mu irangi ihamye, kandi hakorwa irangi ry'umukara wa sulfure rirwanya brittle.

Koresha

Amarangi ya sulfure akoreshwa kugira ngo agabanukemo leukosomu ishongesha mu mazi hamwe na sodium sulfide cyangwa ifu y’ubwishingizi, hanyuma agahindurwa agahinduka ibara ry’umwimerere ridashobora gushonga nyuma yo kwinjizwa n’irangi binyuze mu gushonga cyangwa izindi ngaruka, kugira ngo irangi rikomeze kuri iryo rangi.

Shyiraho umukono

Amarangi ya sulphur akoreshwa cyane mu gusiga irangi imigozi ya cellulose, ahanini akoreshwa mu budodo, imiterere n'indi myenda yo mu nganda n'imyenda iremereye. Ubwoko bukunze gukoreshwa cyane ni sulphur Yuan, sulphur blue,

Umuti ugabanya ubukana

(1) Imiterere y'ibintu bigabanya

1. Imiterere ya Na2S

(1) Nanone izwi nka alkali sulfide, izina risanzwe rya alkali ihumura, imiterere myiza ya alkali sulfide y’inganda muri rusange ni hafi 50%, kandi igaragara nk’umuhondo n’umukara ukomeye. Ni ikintu kigabanya, ariko kandi ni ikintu gikomeye cya alkali, gifite imiterere ihamye. Ubushobozi bwo kugabanya bwa sodium sulfide buri hasi ugereranyije n’ubw’ifu y’ubwishingizi, alkali iri hasi ugereranyije na soda ikaranze kandi iruta ivu rya soda, kandi ifite ingese ikomeye ku ruhu.

(2) Guhindura Sodium sulfide hidrolise kuri NaHS, NaHS ku kugabanya irangi, bigaragara ko ubushobozi bwo kugabanya sodium sulfide bufitanye isano na hydrolise yayo.

(3) Sodium sulfide itanga umwuka wa H2S iyo ihuye na aside, bityo hakwiye kwitonderwa kuyirinda ko ihuzwa na aside.

(4) Guhura na sodium sulfide mu kirere bizakurura amazi, C02, 02, nibindi, ku buryo ibigize neza bigabanuka kandi bigacika buhoro buhoro. Kubwibyo, bigomba gufungwa igihe bibitswe, kandi ibigize byabyo bigomba gupimwa igihe bitazongera gukoreshwa igihe kirekire.

(5) Umuti wa sodium sulfide ntugomba kuba muremure, bitabaye ibyo uzakurwamo umwuka kandi ukagabanya ubushobozi bwawo.
