Nekal BX, sodium butylnaphthalene sulfonate, ifite formulaire zidahuye cyane. Hano hari sodium butyl naphthalene sulfonate na isobutyl naphthalene sulfonate. Hariho uburyo bubiri bwo gukora ingandaNekal BX:
.
② Naphthalene yavanze na n-butanol, hanyuma hongerwamo aside sulfurike. Nyuma yo kutabogama no gukama, ibicuruzwa byarangiye byabonetse. Ibicuruzwa ni ifu yera kandi yoroheje yumuhondo, ushonga mumazi. Irahagaze mumazi akomeye, umunyu, aside hamwe numuti wa alkaline udakomeye, hamwe nubutaka bwera muri soda ya caustic yibanze. Irashobora kongera gushonga nyuma yo kuyungurura amazi. Ibicuruzwa ni ubwoko bwa anion, ibirimo amazi ntibirenza 2%, ibirimo ibyuma ntibirenza 0.01%, pH agaciro ka 1% yumuti wamazi 7 ~ 8.5. Usibye kwinjirira gukomeye, ifite kandi emulisation, gukwirakwiza no kubira ifuro, ubushobozi buke bwo gukora isuku, no guhagarika umukungugu nabi.
Iki gicuruzwa kirashobora gukoreshwa cyane nkicyinjira mugushakisha, guhumeka no gusiga irangi. Irashobora kandi gukoreshwa nk'irangi rya cosolvent, umufasha wo gusiga irangi rya acide irangi, gutatanya umufasha wo gusiga irangi ry'ubwoya, umufasha wo gusiga irangi rya polyamide, umufasha wo gusiga irangi polyester / umufasha wo gusiga irangi.
Koresha
1, ikoreshwa nkibikoresho byinjira mubikorwa byo gucapa no gusiga amarangi. Irashobora kandi gukoreshwa nka detergent, infashanyo yo gusiga irangi, ikwirakwiza, imiti itose, udukoko twica udukoko, imiti yica ibyatsi na emulisiferi mu nganda zikora za rubber.
2. Nka agent yinjira kandi itose, irashobora gukoreshwa muburyo butandukanye bwo gucapa imyenda no gusiga amarangi, nka enzyme desizing, karubone yubwoya, kugabanuka kwa cashmere, chlorine, gutunganya silike ya rayon. Irashobora kandi gukoreshwa nkibikoresho byo guhanagura ibicuruzwa no gukora inganda. Ongeramo 10% penetrant BX igisubizo muri pigment organic ningirakamaro muburyo bwo guhindura amabara. Ikoreshwa nka emulisiferi mugutegura reberi.
3, ibicuruzwa bifite uburyo bwiza bwo gutembera, guhanagura, emulisile, gukwirakwiza no kubira ifuro. Kurwanya aside, kurwanya alkali, kurwanya amazi akomeye, kurwanya umunyu ngenga, kongeramo umunyu muke birashobora kongera cyane ubwinjira. Ikoreshwa cyane mubikorwa bitandukanye byo gucapa imyenda no gusiga amarangi, cyane cyane ikoreshwa nkibikoresho byinjira kandi byangiza, nabyo birashobora gukoreshwa nkibikoresho byo kumesa, gufasha amarangi, gutatanya, kwica udukoko nudukoko, nibindi.
Uburyo bwo gukora
1, naphthalene na butanol, aside sulfurike hamwe na sulfonation. Gukoresha ibikoresho bibisi (kg / t) naphthalene 300 n-butanol 300 octanol 45 umwotsi wa sulfurike 840 aside sulfurike aside 450 caustic soda 190 nta fu 100
2. Gabanya ibice 426 bya naphthalene mubice 478 bya n-butanol, ongeramo ibice 1 060 bya acide sulfurike yibanze hanyuma wongereho ibice 320 bya fumide acide sulfurike. Gabi yashyutswe buhoro kugeza kuri 50-55 ℃ abikwa kuri 6h. Nyuma yo guhagarara, aside iri munsi irekurwa. Igisubizo cyo hejuru cyibisubizo bitagira aho bihuriye na alkali, hanyuma bigahumanya hamwe na sodium hypochlorite, ubutayu, kuyungurura, kuyitera no kumisha kugirango ubone ibicuruzwa byarangiye.
