ʻano
ʻO ke ʻano nui o nā kala sulfur he sulfur ʻeleʻele (CI sulfur ʻeleʻele 1). Hoʻomākaukau ʻia ia ma ka hydrolyzing 2, 4-dinitrochlorobenzene a me ka sodium hydroxide solution i loko o ka sodium dinitrophenol solution ma kahi kokoke e paila ai, a laila hoʻomehana a hoʻolapalapa me ka sodium polysulfide solution ma kahi ratio molecular, a hoʻemi a me ka sulfurizing reaction ma lalo o ke kaomi a i ʻole ke kaomi ʻole. Ma hope o ka pau ʻana o ka hopena sulfurization, hoʻomaloʻo pololei ʻia me kahi mea hoʻomaloʻo wili e loaʻa ai ka dye mua. A laila hoʻohui ʻia i loko o nā dyes kalepa. I ka wā o ka vulcanization, ʻokoʻa ka ratio molecular o ka sodium phenol a me ka sodium polysulfide, ka x (ie, sulfur index) i loko o ka sodium polysulfide Na2Sx a me ka mahana o ka hopena, no laila he ʻokoʻa ke kala o ka huahana sulfur ʻeleʻele o ke kukui ʻōmaʻomaʻo, ke kukui ʻulaʻula ʻōmaʻomaʻo a me ke kukui ʻulaʻula. ʻO ka hemahema nui o ka sulfur black dye ʻo ia ka hanana o ka lole brittle. ʻO kēia no ka mea aia ka sulfide black mole i loko o ka sulfur hana ma ke ʻano o nā kaulahao polysulfide. He paʻa ʻole kēia ʻano o ka sulfur, a i ka wā e hoʻomehana ʻia ai ka dye a i ʻole e kau ʻia i ka ea wela a pulu, maʻalahi ka oxidize i ka sulfuric acid, e hopena ana i ka brittleness o ka lole pulupulu. I nā makahiki i hala iho nei, ma ka hoʻomaikaʻi ʻana i ke kaʻina hana o ka sulfur black, ua hoʻomaʻalili ʻia ka sulfur black maʻamau i kahi 100 ℃ ma hope o ka hana ʻia ʻana, a ua hoʻohui ʻia ka formaldehyde a me ka monochloroacetic acid e hoʻopaʻa i ka sulfur unstable i loko o ka dye, a ua hana ʻia kahi anti-brittle sulfur black dyeing.
Hoʻohana
Hoʻohana ʻia nā dyes sulfur e hoʻemi ʻia i ka leucosome wai-soluble me ka sodium sulfide a i ʻole ka pauka ʻinikua, a laila hoʻololi hou ʻia i ka mea kala insoluble mua ma hope o ka omo ʻia ʻana e ka dye ma o ka oxidation a i ʻole nā hopena ʻē aʻe, i hoʻopaʻa ʻia ai ka dye ma luna o ka dye.
E noi
Hoʻohana nui ʻia nā dyes sulfur i ka hoʻoluʻu ʻana o nā olonā cellulose, hoʻohana nui ʻia i nā olonā, nā ʻano a me nā lole ʻoihana ʻē aʻe a me nā lole kaumaha. ʻO nā ʻano i hoʻohana pinepine ʻia ʻo sulfur Yuan, sulfur blue,
Hoʻonā hoʻemi
(1) Nā ʻano o nā mea hoʻemi
1. Nā Waiwai o Na2S
(1) ʻIke ʻia hoʻi ʻo alkali sulfide, ka inoa maʻamau ʻo smelly alkali, ʻo ka hoʻohui maikaʻi o ka alkali sulfide ʻoihana ma kahi o 50%, a ʻo ke ʻano he melemele-ʻeleʻele paʻa. He mea hoʻemi ia, akā he mea alkali ikaika hoʻi, nā waiwai paʻa. ʻOi aku ka haʻahaʻa o ka hiki ke hoʻemi o ka sodium sulfide ma mua o ka pauka ʻinikua, ʻoi aku ka haʻahaʻa o ka alkalinity ma mua o ka soda caustic a ʻoi aku ka nui ma mua o ka soda lehu, a he ikaika ka palaho i ka ʻili.
(2) ʻO ka hydrolysis sodium sulfide i NaHS, NaHS ma ka hoʻemi ʻana o ka dye, hiki ke ʻike ʻia e pili ana ka hiki ke hoʻemi ʻia ka sodium sulfide i kona hydrolysis.
(3) Hoʻopuka ka sodium sulfide i ke kinoea H2S ke hui pū me ka waikawa, no laila e akahele e pale aku i ka hui pū ʻia ʻana me ka waikawa.
(4) ʻO ka hōʻike ʻana o ka sodium sulfide i ka lewa e omo i ka wai, C02, 02, a pēlā aku, i emi ai ka hoʻohuihui pono a hāʻule mālie. No laila, pono e hoʻopaʻa ʻia i ka wā e mālama ʻia ai, a pono e kālailai ʻia kona ʻano ke ʻole e hoʻohana hou ʻia no ka manawa lōʻihi.
(5) ʻAʻole pono e lōʻihi ka hopena o ka sodium sulfide, inā ʻaʻole e hoʻopau ʻia e ka ea a hōʻemi i kona pono.
