Ibiranga imikorere

Sodium butylnaphthalene sulfonate (CAS 25638-17-9) ni surfactant nziza cyane ya anionic ifite ubushobozi bwo kwinjira, gutose, gukurura, gukwirakwiza no gusohora ifuro. Sodium 4-butylnaphthalene-1-sulfonate ikora neza mu bijyanye no kurwanya aside, kurwanya alkali, kurwanya amazi akomeye no kurwanya umunyu udakomoka ku bimera. Kongeramo umunyu muke bishobora kongera imbaraga zayo zo kwinjira cyane.

Ifite ubushobozi bwo kwinjira neza

Uruvange rwa "butyl hydrophobic chain + naphthalene ring + sodium sulfonate hydrophilic group" mu miterere ya molekile rushobora kwinjira vuba mu cyuho cyangwa mu bice by'ibishishwa ku buso bw'ibikoresho bikomeye nk'imigozi, imyenda, n'uduce tw'ibara. Cyane cyane mu bihe nko gukata ingano y'imyenda no gutera imiti yica udukoko, sodium 2-butyl-1-naphthalenesulfonate ishobora kugabanya cyane igihe cyo kwinjira mu muti (urugero, mu mikorere y'imyenda, umunyu wa sodium wa aside butylnaphtalenesulfonic ushobora gutuma umuti wo gukaraba winjira mu mwenda mu minota 1-3). Byongeye kandi, nyuma yo kongeramo umunyu muto, imbaraga zo kwinjira zishobora kwiyongeraho 30% kugeza kuri 50%, ari na yo nyungu yayo idasanzwe kurusha izindi zinjirira.

Ubushuhe bwinshi

Aside ya Butylnaphtalenesulfonic umunyu wa sodium ushobora gukwirakwiza vuba amazi cyangwa amazi ku buso butobesha amazi (nk'imigozi y'imyenda, amababi y'ibihingwa, n'ubuso bw'ibara) kugira ngo bikore agahu gasa neza, birinda "guhuza ibitonyanga" - urugero, mu nganda zikora impapuro, NekalBX ishobora gukwirakwiza imigozi y'imyanda mu mazi ku buryo bungana, bigagabanya inenge z'impapuro ziterwa no guhuza imigozi. Mu gusiga, Pelex NB ishobora gufasha ibikoresho by'ibanze kunyagisha uduce tw'ibara, bigashyiraho urufatiro rwo gukwirakwiza nyuma.

Imiterere myiza yo gushonga no gukwirakwiza

Umutungo wo gusya:NekalBXishobora gukwirakwiza neza igice cy'amavuta (nk'ibintu bikora imiti yica udukoko, monomers za rubber) mu gice cy'amazi kugira ngo habeho emulsion imwe (urugero, nyuma yo kuvanga umuti ushobora gushonga n'amazi, sodium 2-butyl-1-naphthalenesulfonate ishobora kugumana amasaha arenga 4 idashyizwe mu byiciro).

Uburyo bwo gukwirakwira: Umunyu wa sodium ukomoka kuri aside ya butylnaphtalenesulfonike ugira uruhare rwiza mu gukwirakwiza no gushimangira uduce duto (nk'amabara n'amabara y'irangi), kandi ushobora gukumira kwivanga kw'uduce duto. Urugero, mu gusiga irangi no gucapa, ushobora kugumana uduce duto tw'irangi ku ngano imwe ya 1-5μm, ukirinda ko habaho "amabara ateye nk'imirongo" mu gihe cyo gusiga irangi.

Imiterere iciriritse yo gusohora ifuro

Mu gihe cyo kuvanga cyangwa gutemba, hazakorwa ingano runaka y'ifuro. Ifuro rishobora gufasha mu guhagarika uduce duto (nk'utwongera mu gukora impapuro), ariko ifuro ntiriba ryihariye (ntibyoroshye gukora "udusimba twapfuye" bigoye gukuraho), kandi nta mpamvu yo kongeramo ingano nini ya defoamer nyuma. Aside ya Butylnaphtalenesulfonic sodium salt izirikana "ubufasha bwo guhagarika" ndetse n' "uburyo bworoshye bwo kuvurwa nyuma".

Imikoreshereze y'ingenzi

1. Ahantu ho gucapa no gusiga amarangi ku myenda (aho gukoresha cyane)

Iyi ni yo miterere y'ingenzi ikoreshwa mu gupima umunyu wa sodium ukomoka kuri butylnaphtalenesulfonike, ukoreshwa cyane cyane nk'umusemburo utuma umuntu yinjira mu mubiri, ukamutose kandi ukamusiga amarangi:

Uburyo bwo kuvura mbere y’uko ivurwa: Iyo hiyongereyeho mu gihe cyo gukata ingano, gukata, gushyiramo karuboni, gukurura, gukaranga chlorine n’izindi nzira z’imyenda, sodium 4-butylnaphthalene-1-sulfonate ishobora kugabanya vuba ubushyuhe bw’amazi, bigatuma amazi yo kuvura (nk’amazi yo kugabanya ingano, amazi yo kugabanya) yinjira neza imbere mu myenda, bikanoza uburyo imyanda ikurwamo (nk’ingano, ishashi), kandi icyarimwe birinda inenge mu myenda bitewe no kutareshya.

Uburyo bwo gushushanya/gucapa: Nk'ikintu gihindura irangi kandi gihindura irangi,Pelex NBishobora kunoza uburyo amarangi ashonga no gukwirakwira mu mazi, igafasha amarangi gufatana neza n'imigozi, igagabanya ibibazo byo gutandukana kw'amabara n'ibara, kandi ikwiriye cyane cyane mu gusiga irangi ku migozi karemano nk'ipamba n'ishati, ndetse n'imyenda ivanze.

Uburyo bwo kurangiza nyuma yo kuvurwa: Gufasha ibintu bikora neza (nk'ibirwanya iminkanyari n'ibindi bigabanya iminkanyari) kwinjira kugira ngo bifashe neza ko kurangiza neza umwenda.

2. Ishami ry'amabara, inki n'amakoli

Ikoreshwa cyane cyane nk'icyuma gikwirakwiza:

Mu gukora amarangi, irangi rikozwe mu mazi n'iwino, kongeramo sodium butylnaphthalene sulfonate bishobora gukwirakwiza irangi ku buryo bungana (nka titanium dioxide na carbone black) n'ibirungo mu bikoresho by'ibanze, bikarinda irangi guterana, bikanoza ihinduka, ibara ringana kandi rigahinduka, kandi icyarimwe hirindwa ko irangi rihinduka mu buryo butaringaniye cyangwa ngo rihinduke mu gihe cyo kubika.

Mu gutegura kole, umunyu wa sodium ukomoka kuri butylnaphtalenesulfonic ushobora kunoza uburyo resins n'ibirungo bikwirakwira, no kongera imbaraga zo gufatanya no kudahungabana kw'ibirungo.

3. Inganda zikora impapuro

Nk'ikintu gitanga amazi n'umuti wo gutandukanya:

Mu gihe cyo gutegura impumuro y'ibinure, umunyu wa sodium ukomoka kuri butylnaphtalenesulfonic ufasha imiti (nk'imiti igabanya ubushyuhe, imiti itekesha) kwinjira vuba mu migozi y'impumuro y'ibinure, bikongera imikorere myiza yo kuyitunganya;

Mu gihe cyo gukora impapuro, aside butylnaphtalenesulfonic sodium salt 25638-17-9 ifasha mu gukwirakwiza fibres na fillers (nk'ifu ya calcium carbonate, talcum), igabanya fibre agglomeration, kandi ikongera uburinganire, imbaraga n'ubuso bw'impapuro.

4. Umurima w'imiti yica udukoko

Nk'inyongeramusaruro y'imiti yica udukoko (ikoreshwa mu gutera imiti, emulsifier):

Iyo yongewemo mu gutegura imiti yica udukoko, imiti yica udukoko n'imiti yica udukoko, Pelex NB ishobora kongera ubushobozi bwo gutosesha no kwinjira mu muti w'amazi ku buso bw'ibihingwa (cyangwa ku buso bw'ibyatsi n'udukoko), ikamena urwego rw'ibishishwa by'imbuto, igatuma ibintu bikora byinjira mu murima vuba, ikanoza uburyo imiti yica udukoko ikoreshwa n'uburyo ikoreshwa, kandi ikagabanya imyanda iterwa no "gusohoka" k'umuti w'amazi.

5. Andi mashami y'inganda n'ay'ibinyabutabire ya buri munsi

Inganda za Rubber: Sodium 2-butyl-1-naphthalenesulfonate ikora nk'inyunganizi mu gutegura ifu ya rubber (nk'ifu karemano na latex y'inyunganizi), ifasha ibice bya rubber gukwirakwira mu mazi, yongera ubuziranenge bwa latex, kandi yorohereza gutunganya nyuma (nk'ipfundikizo no gushushanya).

Mu rwego rw'imiti ikoreshwa buri munsi: Aside ya Butylnaphtalenesulfonic umunyu wa sodium ukoreshwa mu rugero ruto mu isabune n'ibikoresho byo gusukura kugira ngo wongere ubushobozi bwo gukuraho ubwandu. Cyangwa ushobora gukoreshwa nk'umusemburo mu mavuta amwe na amwe yo kwisiga (nk'amavuta yo kwisiga n'amavuta) kugira ngo wongere imiterere y'umusaruro kandi uhamye.

Turi umwuga mu gukora ibikoresho fatizo bya shimi kandi twagize uruhare mu gukoraaside butylnaphtalenesulfonic umunyu wa sodiumhafi imyaka makumyabiri. Niba ukeneye iki gicuruzwa, twandikire igihe icyo ari cyo cyose.
