rudzi
Mhando huru yemadhayi esulfure iblack sulphur (CI sulphur black 1). Inogadzirwa ne hydrolyzing 2, 4-dinitrochlorobenzene uye sodium hydroxide solution mu sodium dinitrophenol solution painoda kufashaira, yozodziiswa nekufashaira ne sodium polysulfide solution pa some molecular ratio, uye kuderedza uye sulphurizing reaction pasi pekumanikidzwa kana pasina kumanikidzwa. Mushure mekunge sulphurization reaction yapera, inoomeswa zvakananga ne roller dryer kuti iwane dhayi rekutanga. Yobva yasanganiswa mumadhayi ekutengeserana. Munguva ye vulcanization, molecular ratio ye sodium phenol ne sodium polysulfide, x(kureva, sulfur index) mu sodium polysulfide Na2Sx uye reaction tembiricha zvakasiyana, zvekuti ruvara rwe sulphur black product rune musiyano we green light, green red light ne red light. Dambudziko guru re sulphur black dye inyaya ye brittle cloth. Izvi zvinodaro nekuti sulphur black molecule ine active sulfur muchimiro che polysulfide chains. Musanganiswa uyu wesarufa hauna kugadzikana, uye kana dhayi ikapiswa kana kuiswa mumhepo inopisa uye ine hunyoro, zviri nyore kuoxidize kuita sulfuric acid, zvichikonzera kuputsika kwejira redonje. Mumakore achangopfuura, nekuvandudza maitiro ekugadzira sarufa nhema, sarufa nhema yakajairika inotonhodzwa kusvika pa100℃ mushure mekugadzirwa, uye formaldehyde ne monochloroacetic acid zvinowedzerwa kuti sarufa isina kugadzikana igare mudhayi, uye dhayi nhema yesarufa inorwisa kuputsika inogadzirwa.
Shandisa
Dhayi dzesarufa dzinoshandiswa kuderedza kuita leucosome inonyungudika mumvura ne sodium sulfide kana insurance powder, dzozochinjwa kuita zvinhu zvepakutanga zvisina kunyungudika mushure mekutorwa nedhayi kuburikidza ne oxidation kana zvimwe zvinokanganisa, kuitira kuti dhayi rigare padhayi.
Isa chikumbiro
Madhayi esulfure anoshandiswa zvakanyanya mukudhaya mafiber ecellulose, anonyanya kushandiswa mushinda, maumbirwo nemamwe machira emaindasitiri uye machira anorema. Mhando dzinonyanya kushandiswa ndedzesarufa Yuan, sarufa bhuruu,
Mhinduro yekuderedza
(1) Hunhu hwezvinhu zvinoderedza simba remushonga
1. Hunhu hweNa2S
(1) Inozivikanwawo sealkali sulfide, zita rinowanzo shandiswa sealkali inonhuwa, muumbirwo unoshanda wealkali sulfide yeindasitiri unowanzoita 50%, uye chitarisiko chayo chakatsvuka-tsvuku. Inoderedza, asiwo ine alkali yakasimba, ine hunhu hwakagadzikana. Kugona kwayo kuderedza sodium sulfide kwakaderera pane kwehupfu hweinshuwarenzi, alkalinity yakaderera pane caustic soda uye yakakura kupfuura soda ash, uye ine ngura yakasimba paganda.
(2) Sodium sulfide hydrolysis kuenda kuNaHS, NaHS pakuderedza dhayi, zvinogona kuonekwa kuti kugona kwekuderedza sodium sulfide kwakabatana nehydrolysis yayo.
(3) Sodium sulfide inoburitsa gasi reH2S kana yasangana neasidhi, saka kungwarira kunofanira kuitwa kudzivirira kuti isasanganiswe neasidhi.
(4) Kusangana neSodium sulfide mumhepo kunotora mvura, C02, 02, nezvimwewo, zvekuti musanganiswa unoshanda unodzikira uye unokundikana zvishoma nezvishoma. Saka, inofanira kuvharwa kana yachengetwa, uye musanganiswa wayo unofanirwa kuongororwa kana isingachashandiswizve kwenguva yakareba.
(5) Sodium sulfide solution haifanirwe kureba, zvikasadaro ichapiswa nemhepo uye inoderedza kushanda kwayo.

Inonyanya kushandiswa pakudhaya donje, hemp fiber
Kambani yedu inonyanya kugadziraSarufa nhema yebhuruu,Sulfur Bhuruu Bhuruu 150%,Tsvuku yeSulfur 14,Madhayi matsvuku eSulfuruye mamwe madhayi esulfure akawanda, anotengeswa kumba nekune dzimwe nyika, akadai seBangladesh, Pakistan, Turkey, India, Vietnam, Italy, nezvimwewo. Yakagamuchirwa uye yakarumbidzwa nevatengi vazhinji, nekuda kwekutarisira kwedu kwakanaka uye mabhenefiti emitengo yakaderera. Tinotendawo vatengi vedu nekutsigira kwavo nekuziva kambani yedu.
