Nekala BX, sodium butylnaphthalene sulfonate, ili ndi ma formula osagwirizana kwambiri. Pali sodium butyl naphthalene sulfonate ndi isobutyl naphthalene sulfonate. Pali njira ziwiri zopangira mafakitaleNekala BX:
(1) Naphthalene ndi yemweyo kulemera kwa sulfuric asidi sulfonation, mapangidwe α -naphthalene sulfonic asidi, pansi kwambiri yogwira ntchito nthawi yomweyo kuwonjezera anaikira sulfuric asidi ndi n-butanol, pambuyo kulekana, neutralization, evaporation.
② Naphthalene inasakanizidwa ndi n-butanol, ndipo sulfuric acid yowonjezera inawonjezeredwa. Pambuyo pa neutralization ndi kuyanika, chomalizidwacho chinapezedwa. Izi ndi woyera ndi kuwala chikasu ufa, sungunuka m'madzi. Ndiwokhazikika m'madzi olimba, mchere, asidi ndi njira yofooka ya alkaline, ndi madzi oyera mumadzi a caustic soda. Ikhoza kusungunukanso mutatha kusungunuka ndi madzi. Mankhwalawa ndi amtundu wa anion, okhutira ndi madzi osapitirira 2%, chitsulo sichiposa 0.01%, pH mtengo wa 1% yankho lamadzimadzi 7 ~ 8.5. Kuphatikiza pa permeability wamphamvu, ilinso ndi emulsification, kufalikira ndi kutulutsa thovu, kusakhoza kuyeretsa bwino, komanso kuyimitsidwa koyipa kwa fumbi.
Izi zitha kugwiritsidwa ntchito kwambiri ngati zolowera m'njira zopaka utoto, zopaka utoto komanso utoto. Itha kugwiritsidwanso ntchito ngati utoto wa cosolvent, wothandizira utoto wopaka utoto wa asidi, wothandizira utoto wopaka utoto wa utoto, wothandizira utoto wopaka utoto wa polyamide, wothandizira utoto wopaka utoto wa polyester / thonje wophatikizika wopaka utoto.
ntchito
1, yomwe imagwiritsidwa ntchito ngati njira yolowera mumakampani osindikiza nsalu ndi utoto. Itha kugwiritsidwanso ntchito ngati zotsukira, zothandizira utoto, dispersant, wonyowetsa, mankhwala ophera tizilombo, herbicide ndi emulsifier mumakampani opanga mphira.
2. Monga wolowera komanso wonyowetsa, angagwiritsidwe ntchito m'njira zosiyanasiyana zosindikizira nsalu ndi utoto, monga enzyme desizing, ubweya wa carbonization, kuchepa kwa cashmere, chlorination, silika wa rayon. Itha kugwiritsidwanso ntchito ngati chonyowetsa pakupanga mapepala ndi makampani am'nyanja. Kuwonjezera 10% yankho lolowera la BX mu organic pigment ndikopindulitsa pakusinthira phala. Amagwiritsidwa ntchito ngati emulsifier pokonzekera mphira zamkati.
3, mankhwala ali permeability kwambiri, kunyowetsa, emulsification, kufalikira ndi thobvu katundu. Mu kukana kwa asidi, kukana kwa alkali, kukana kwamadzi olimba, kukana kwa mchere, kuwonjezera mchere pang'ono kumatha kukulitsa mphamvu. Amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zamakampani osindikizira nsalu ndi utoto, omwe amagwiritsidwa ntchito kwambiri ngati chowongolera komanso chonyowetsa, amathanso kugwiritsidwa ntchito ngati zotsukira, zothandizira utoto, dispersant, mankhwala ophera tizilombo ndi herbicide, etc.
Njira zopangira
1, naphthalene ndi butanol, sulfuric acid ndi sulfonation condensation. Kugwiritsa ntchito zopangira (kg/t) naphthalene 300 n-butanol 300 octanol 45 utsi wa sulfuric acid 840 sulfuric acid 450 caustic koloko 190 wopanda ufa 100
2. Sungunulani magawo 426 a naphthalene mu magawo 478 a n-butanol, onjezerani magawo 1 060 a sulfuric acid yokhazikika ndikuwonjezera magawo 320 a fuming sulfuric acid pansi pa mukubwadamuka. Gabi adatenthedwa pang'onopang'ono mpaka 50-55 ℃ ndikusungidwa kwa 6h. Pambuyo pa kuyima, asidi wapansi amamasulidwa. The chapamwamba anachita njira ndi neutralized ndi mchere, ndiyeno bleached ndi sodium hypochlorite, sedimentation, kusefera, kupopera mbewu mankhwalawa ndi kuyanika kupeza yomalizidwa mankhwala.
