Nā waiwai: ʻulaʻula-ʻulaʻula pauka.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka solution sodium sulfide he ʻōmaʻomaʻo-hina.He ʻulaʻula-ʻulaʻula ia i loko o ka ʻakika sulfuric concentrated a ua hoʻoheheʻe ʻia i kahi ʻeleʻele uliuli ʻeleʻele.Lilo ke kala i kala ʻoliva māmā melemele i loko o ka solution insurer pauda alkaline, a hiki ke hoʻihoʻi ʻia ke kala kumu ma hope o ka hoʻonā ʻana;Ua mae loa i ka solution sodium hypochlorite;Huli ʻeleʻele ʻeleʻele ma luna o ka sulfuric acid

Kaʻina hana: nitrosation o ka phenol sodium nitrite a me ka sulfuric acid e hana ai i ka p-nitrosyphenol, condensation me ka o-toluidine i hoʻoheheʻe ʻia i ka sulfuric acid, ka hoʻohaʻahaʻa a me ka vulcanization me ka sodium polysulfide me kahi helu noʻonoʻo sulfur, a laila ma o ke kinoea oxidation, a ma hope o ka kānana. , hoʻomaloʻo, ʻokiʻoki a me ka hana maʻamau e hana i nā huahana.ʻAi meaʻai maka (kg/t) O-toluidine (99%) 165-210 phenol (ʻoihana) 185-220 sodium nitrite 195-230 caustic soda (100%) 1-20 soda lehu (ʻoihana) 920-1120 sulfuric acid ( 100%) 900-1160 sulfur (99%) 430 sodium sulfide (63.5%) 480-620 Yuan pauka 10

Hoʻohana: He kūpono ia no ke kala ʻana i ka pulupulu, hemp, viscose a me kāna mau lole, a hiki ke hoʻohana ʻia no ke kala ʻana i ka vinylon.Hoʻoluʻu ʻia kēia huahana i ka ʻulaʻula nui, ʻoi aku ka mālamalama o ke kala.ʻAʻole maikaʻi ka paʻa ʻana o ke kaʻina hana wai, maʻalahi ke hoʻokahe i hoʻokahi haneli ʻulaʻula, ākea, ʻulaʻula a me nā hemahema ʻē aʻe, ʻoi aku ka Sulfur blue BRN, Sulfur blue 7 ʻoi aku ka maʻalahi o ka haku.ʻO ka hoʻohana ʻana i ka pad dyeing hiki ke hōʻemi i ka ʻulaʻula, erythema a me nā hemahema ʻē aʻe.No ka mea ʻokoʻa ka helu o nā pūʻulu o ka sodium polysulfide i hoʻohana ʻia i ka hana ʻana o kēia huahana, ʻokoʻa nā kala ʻokoʻa o nā kala kalepa.Kapa ʻia ka ʻulaʻula uliuli Sulfur blue 7, kapa ʻia ke kukui ʻulaʻula uliuliSulfur Blue 7, a ua kapa ʻia ke kukui ʻulaʻula Sulfur blue 7, pono e nānā ʻia ke hoʻohana ʻia.Hiki ke hana ʻia ka sulfur blue 7 ma o ka hoʻohana ʻana i ka o-nitroethylbenzene, kahi huahana ma ka hana ʻana i ka chloramphenicol, ma kahi o ka o-toluidine.
