Nambala ya CAS:1327-57-7

Kapangidwe kake: ufa wabuluu-wofiirira. Wosasungunuka m'madzi, wosungunuka mu yankho la sodium sulfide ndi wobiriwira-imvi. Ndi wabuluu-wofiirira mu sulfuric acid yokhazikika ndipo umasungunuka kukhala buluu wakuda. Utotowo umakhala mtundu wachikasu wowala wa azitona mu yankho la alkaline insurance powder, ndipo mtundu woyambirira ukhoza kubwezeretsedwa pambuyo pa oxidation; Umazimiririka kwathunthu mu yankho la sodium hypochlorite; Umasanduka wofiirira wakuda pa sulfuric acid yokhazikika

Njira Yopangira: Kutulutsa nitrosation ya phenol sodium nitrite ndi sulfuric acid kuti apange p-nitrosyphenol, kusungunuka ndi o-toluidine mu sulfuric acid, kuchepetsa ndi kusungunuka ndi sodium polysulfide ndi nambala inayake ya sulfure reflection, kenako kudzera mu mpweya oxidation, ndipo potsiriza kudzera mu kusefa, kuumitsa, kuphwanya ndi kukonza kokhazikika kuti apange zinthu. Kugwiritsa ntchito zinthu zopangira (kg/t) O-toluidine (99%) 165-210 phenol (yamafakitale) 185-220 sodium nitrite 195-230 caustic soda (100%) 1-20 soda phulusa (yamafakitale) 920-1120 sulfuric acid (100%) 900-1160 sulfure (99%) 430 sodium sulfide (63.5%) 480-620 Yuan powder 10

Ntchito: Ndi yoyenera kupaka utoto thonje, hemp, viscose ndi nsalu zake, ndipo ingagwiritsidwenso ntchito kupaka utoto vinylon. Chogulitsachi chimapakidwa utoto wabuluu wakuda, mtundu wake ndi wowala kwambiri. Kukhazikika kwa njira yopaka utoto ndi kofooka, kosavuta kusakaniza m'mphepete mwa zofiira zana, mopingasa, malo ofiira ndi zolakwika zina, makamaka buluu wa Sulphur BRN, buluu wa Sulphur 7 ndikosavuta kugwiritsa ntchito. Kugwiritsa ntchito utoto wa pad kungachepetse m'mphepete wofiira, erythema ndi zolakwika zina. Chifukwa kuchuluka kwa magulu a sodium polysulfide omwe amagwiritsidwa ntchito popanga mankhwalawa ndi kosiyana, utoto wamalonda uli ndi mitundu yosiyanasiyana. Kuwala kwabuluu kumatchedwa buluu wa Sulphur 7, kuwala kofiira kwabuluu kumatchedwaBuluu wa Sulphur 7, ndipo kuwala kofiira kumatchedwa Sulphur blue 7, komwe kuyenera kusamalidwa bwino mukamagwiritsa ntchito. Sulphur blue 7 ikhoza kupangidwa pogwiritsa ntchito o-nitroethylbenzene, chinthu china chomwe chimapanga chloramphenicol, m'malo mwa o-toluidine.

Kampani yathu imapanga zinthu zambiriSulfa wakuda, Sulphur Madzi Akuda, Buluu wa Sulphur 7Kutumiza zinthu ku Bangladesh kosatha. India. Pakistan. Egypt, ndi Iran. Kupereka ndi khalidwe lake zonse ndi zokhazikika. Chofunika kwambiri ndi ubwino wa mtengo.
