He aha kāu ʻike e pili ana i ka Sulfur Dyes(2)?

hanau

ʻO ke ʻano nui o nā mea kala sulfur ʻeleʻele (CI sulfur black 1).Hoʻomākaukau ʻia e ka hydrolyzing 2, 4-dinitrochlorobenzene a me ka sodium hydroxide solution i ka hopena sodium dinitrophenol ma kahi kokoke i ka paila, a laila hoʻomehana a hoʻolapalapa ʻia me ka solution polysulfide sodium ma kekahi lākiō mole, a me ka hoʻohaʻahaʻa a me ka sulfurizing pane ma lalo o ke kaomi a ʻaʻohe kaomi.Ma hope o ka pau ʻana o ka hopena sulfurization, hoʻomaloʻo pololei ʻia me ka roller dryer no ka loaʻa ʻana o ke kala kumu.A laila hoʻohui ʻia i loko o nā kala kalepa.I ka wā vulcanization, ʻokoʻa ka lākiō mole o ka sodium phenol a me ka sodium polysulfide, ka x (ie, sulfur index) i ka sodium polysulfide Na2Sx a me ka wela o ka hopena, ʻokoʻa ke kukui kala o ka huahana ʻeleʻele sulfur i ka ʻokoʻa o ke kukui ʻōmaʻomaʻo, ʻōmaʻomaʻo. kukui ʻulaʻula a me ke kukui ʻulaʻula.ʻO ka pōʻino nui o ka sulfur ʻeleʻele ʻeleʻele ke ʻano o ka lole palupalu.ʻO kēia ke kumu o ka mole ʻeleʻele sulfide i loko o ka sulfur hana ma ke ʻano o nā kaulahao polysulfide.ʻAʻole paʻa kēia hui ʻana o ka sulfur, a i ka wā e wela ai ka wai kala a waiho ʻia i loko o ka ea wela a me ka haʻahaʻa, ua maʻalahi ke hoʻoheheʻe ʻia i ka waikawa sulfuric, e hopena i ka brittleness o ka lole pulupulu.I nā makahiki i hala iho nei, ma ka hoʻomaikaʻi ʻana i ke kaʻina hana o ka ʻeleʻele sulfur, ua hoʻomaha ʻia ka ʻeleʻele sulfur maʻamau i kahi 100 ℃ ma hope o ka hana ʻia ʻana, a hoʻohui ʻia ka formaldehyde a me ka waikawa monochloroacetic e hoʻopaʻa i ka sulfur paʻa ʻole i ka wai, a me kahi ʻeleʻele anti-brittle sulfur. hana ʻia ke kala ʻana.

Hoʻohana

Hoʻohana ʻia nā wai sulfur e hoʻemi ʻia i ka leucosome hiki ke hoʻoheheʻe ʻia i ka wai me ka sodium sulfide a i ʻole ka pauka ʻinikua, a laila hoʻololi hou ʻia i ka mea kala ʻole hiki ke hoʻololi ʻia ma hope o ke komo ʻana e ka wai ma o ka oxidation a i ʻole nā ​​​​hopena ʻē aʻe, i paʻa ke kala i ka wai. .

E noi

hoʻohana nui ʻia nā sulfur dyes i ka pena ʻana i nā fiber cellulose, hoʻohana nui ʻia i nā wili, nā ʻano a me nā lole ʻoihana ʻē aʻe a me nā lole kaumaha.ʻO nā ʻano mea maʻamau i hoʻohana ʻia he sulfur Yuan, sulfur blue,

Haʻina hoʻoemi

(1) Nā waiwai o nā mea ho'ēmi

1. Na waiwai o Na2S

(1) ʻIke ʻia hoʻi ʻo alkali sulfide, ka inoa maʻamau smelly alkali, ʻo ka hoʻohui maikaʻi ʻana o ka ʻenehana alkali sulfide ma kahi o 50%, a ʻo ke ʻano he melemele-ʻeleʻele paʻa.He mea ho'ēmi ia, akā he mea ikaika alkali, waiwai paʻa.ʻOi aku ka haʻahaʻa 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 corrosion i ka ʻili.

(2) Sodium sulfide hydrolysis i NaHS, NaHS ma ka ho'ēmi wai, hiki ke 'ike 'ia e pili ana ka sodium sulfide reduction capacity i kona hydrolysis.

(3) Hoʻopuka ka sodium sulfide i ke kinoea H2S i ka wā e hui ai i ka ʻakika, no laila pono e mālama ʻia e pale aku i ka hui ʻana me ka waikawa.

(4) ʻO ka hoʻolaha ʻana o ka sodium sulfide i ka lewa e hoʻopaʻa i ka wai, C02, 02, etc., no laila e emi iho ka haku mele maikaʻi a hāʻule mālie.No laila, pono e hoʻopaʻa ʻia i ka wā e mālama ʻia ai, a pono e nānā ʻia kona haku mele ʻana ke hoʻohana ʻole ʻia no ka manawa lōʻihi.

(5) ʻAʻole pono e lōʻihi ka hopena o ka sodium sulfide, i ʻole e hoʻoneʻe ʻia e ka ea a hoʻemi i kona pono.

hoʻohana

Hoʻohana nui ʻia no ka pulupulu, hemp fiber dyeing

Hoʻopuka nui kā mākou huiSulfur ʻeleʻele ʻulaʻula,Sulfur Blue Brn 150%,ʻulaʻula sulfur 14,Na Wai ʻulaʻula Sulfura me nā meaʻokoʻa sulfur ʻē aʻe, i kūʻai ʻia ma ka home a ma waho, e like me Bangladesh, Pakistan, Turkey, India, Vietnam, Italia, etc. pono kūʻai.Mahalo pū mākou i kā mākou mea kūʻai aku no kā lākou kākoʻo a ʻike i kā mākou hui.
