8. Ngubani igamaNekal BXIsodium butyl iNaphthalene Sulfonate? Zombini iSodium butyl naphthalene sulfonatekunye ne-isobutyl sodium sulfonate. Kukho iindlela ezimbini zemveliso ye-Nekal BX:

(1) I-Naphthalene kunye nobunzima obufanayo be-sulfuric acid sulfonation, ukubunjwa kwe-α -naphthalene sulfonic acid, phantsi kokuvuselela okukhulu ngexesha elifanayo ukongeza i-sulfuric acid kunye ne-n-butanol, emva kokuhlukana, ukungathathi hlangothi, ukukhuphuka.

② I-Naphthalene ixutywe kunye ne-n-butanol, kwaye i-asidi ye-sulfuric egxininisiweyo yongezwa. Emva kokungathathi hlangothi kunye nokomisa, imveliso egqityiweyo yafunyanwa. Le mveliso imhlophe kunye nomgubo ophuzi okhanyayo, onyibilikayo emanzini. Uzinzile kumanzi anzima, ityuwa, i-asidi kunye nesisombululo se-alkaline esibuthathaka, kwi-concentrated caustic soda white precipitation, yongeza amanzi emva kokuhlanjululwa kunokuchithwa kwakhona.

Imveliso luhlobo lwe-anion, umxholo wamanzi awukho ngaphezu kwe-2%, umxholo wesinyithi awukho ngaphezu kwe-0.01%, ixabiso le-pH le-1% isisombululo samanzi 7 ~ 8.5. Ukongeza kwi-permeability eyomeleleyo, ikwane-emulsification, i-diffusion kunye neempawu zogwebu, ukungakwazi ukucoca okungalunganga, kunye nokumiswa kakubi kothuli. Le mveliso ingasetyenziswa ngokubanzi njengendawo yokungena ekukhuhleni, kwi-bleaching kunye neenkqubo zokudaya. Isenokusetyenziswa njengedayi ye-cosolvent, i-asidi yedayi yedayi umncedisi wokudaya, umncedisi wokudaya wedayi wedayi, ilaphu elidityanisiweyo le-polyamide umncedisi wokudaya, ukusasaza idayi ye-polyester / umqhaphu odityanisiweyo wokuncedisa ilaphu lokudaya. Iimpawu zemichiza Umgubo omhlophe okanye omthubi. Inyibilika emanzini.

Ukusetyenziswa kwelaphu, ushicilelo kunye nokudaya, ufele kunye neshishini lephepha, kunye nezinambuzane, iarhente yokumanzisa ukhula, ipeyinti kunye ne-inki yokuchitha i-ejenti, i-emulsifier yoshishino lwerabha isebenzisa i-Chemicalbook njengendawo yokungena kushicilelo lwelaphu kunye neshishini lokudaya. Isenokusetyenziswa njengesicoci, isincedisi sedayi, i-dispersant, i-ejenti yokumanzisa, isibulali-zinambuzane, imichiza yokutshabalalisa ukhula kunye ne-emulsifier kwishishini lerabha yokwenziwa. Ukusetyenziswa njengearhente yokuntywila kunye nearhente yokumanzisa, ingasetyenziswa kwiinkqubo ezahlukeneyo zoshicilelo lwelaphu kunye neshishini lokudaya, njenge-enzyme desizing, i-carbonization yoboya, ukucutheka kwe-cashmere, i-chlorination, unyango lwesilika ye-rayon.CAS:25638-17-9.

Isenokusetyenziswa njenge-arhente yokumanzisa kwi-papermaking nakwishishini lechibi. Ukongeza i-10% yesisombululo se-BX esingena kwi-organic pigment kunenzuzo ekumodareyitheni kombala. Isetyenziswe njenge-emulsifier ekulungiseleleni i-pulp yerabha. Imveliso inokugqwesa okugqwesileyo, ukumanzisa, i-emulsification, i-diffusion kunye neempawu zogwebu. Ekuxhathiseni i-asidi, ukuxhathisa kwealkali, ukuxhathisa amanzi anzima, ukuxhathisa ityuwa ye-inorganic, ukongeza inani elincinci letyuwa kunokunyusa kakhulu ukugqithiswa. Isetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zoshicilelo lwelaphu kunye neshishini lokudaya, ikakhulu lisetyenziswa njenge-ejenti etyhutyhayo kunye ne-ejenti yokumanzisa, nayo ingasetyenziswa njengesicoci, isincedisi sedayi, i-disperant, i-insecticide kunye ne-herbicide, njl. ukujiya.

Ukusetyenziswa kwezinto ezikrwada (kg/t) I-naphthalene esulungekisiweyo 300 n-butanol 300 sec-octanol 45 I-asidi evuthayo ye-sulfuric 840 450 i-sulfate caustic soda 190 umgubo othuleyo 100 Indlela yokuvelisa Ukunyibilikisa i-naphthalene 426 iinxalenye kwi-478 i-sulfuric 0 i-concentric acid 0 i-concentrate ye-1 ye-n-centuric 1 ukuxhokonxa, uze wongeze i-asidi evuthayo sulfuric 320 iinxalenye. I-Gabi yayifudunyezwa kancinane ukuya kwi-50-55 ℃ kwaye igcinwe i-6h. Emva kokuma, i-asidi engaphantsi ikhutshwa. Isisombululo esiphezulu sokusabela singathathi hlangothi ngealkali, kwaye emva koko sixutywe nge-sodium hypochlorite, i-sedimentation, i-filtration, ukutshiza kunye nokomisa ukufumana imveliso egqityiweyo.
