Bis (4-hydroxyphenyl) Sulfone CAS 80-09-1
Bisphenol S (BPS), inomero ya CAS 80-09-1 n'izina rya shimi Bis (4-hydroxyphenyl) Sulfone, ni ikintu gihumura kigizwe n'imiterere ya bisphenol ihujwe n'itsinda rya sulfone. Bitewe n'uko itsinda rya sulfone (-SO₂-) rihagaze neza kandi rihamye mu miterere ya molekile, imikorere yaryo itandukanye cyane n'iya bisphenol A (BPA) isanzwe, bigatuma ikoreshwa cyane mu nganda za shimi, ibikoresho, n'ibinyabutabire bya buri munsi.

1. Ibikoresho bya polymer: Monomer z'ibanze n'izihindura
Gutunganya Epoxy Resin: Nk'ikintu gisimbura bisphenol A monomer, ihuzwa na epichlorohydrin kugira ngo ikore "bisphenol S-type epoxy resin." Iyi resin igaragaza ubushobozi bwo guhangana n'ubushyuhe bwinshi (ubushyuhe bw'impinduka mu kirahuri (Tg) buri hagati ya 30-50°C na bisphenol A epoxy resin), ubushobozi bwo guhangana n'ubushyuhe, n'imbaraga za mekanike. Bis (4-hydroxyphenyl) sulfone ikoreshwa mu bikoresho by'ikoranabuhanga bipfunyikamo ubushyuhe bwinshi, kole z'imiterere y'ikirere, n'imyambaro irwanya ubushyuhe.
Uburyo bwa Polycarbonate (PC): Ikoreshwa mu gukora "bisphenol S-type PC", yongera ubushobozi bwo kudashyuha no kudasaza kwa UV ku bikoresho bya PC. Ikwiriye gukoreshwa nko mu mazu y'amatara yo hanze no ku bisenge by'imodoka.
Guhindura Polysulfone Resin: Bis (4-hydroxyphenyl) sulfone ikoreshwa nk'ikintu kimwe mu gukora resin za polysulfone, yongera ubushobozi bwo kudakora neza kw'imisemburo ya resin ndetse n'ubushobozi bwo kuyikoresha. Ikoreshwa mu bikoresho byo kwa muganga bigezweho (nk'ibikoresho bya dialyzer) n'ibikoresho by'ikoranabuhanga.
2. Imiti n'imyenda bya buri munsi: Inyongeramusaruro zikoreshwa
Ibikoresho by'umwimerere byo kwisiga: Bis (4-hydroxyphenyl) sulfone yongerwa mu bisigazwa by'izuba n'ibicuruzwa byo kwita ku ruhu nk'ikintu gifata UV cyangwa antioxydant. Ikoresheje imiterere ya antioxydant ya phenolic hydroxyl hamwe n'uburyo itsinda rya sulfone rihagaze neza, igabanya kwangirika kwa UV ku ruhu kandi ikongera igihe cyo kuruhuka cy'umuti.
Inyunganizi mu myenda: Bis (4-hydroxyphenyl) sulfone ikoreshwa mu gukora ibintu bigabanya umuriro cyangwa ibintu birwanya static. Mu gukorana n'amatsinda ya hydroxyl ku buso bwa fibre kugira ngo bifatanye neza, bitanga ubushobozi bwo kudashira umuriro n'ubushobozi bwo kudashira ku mwenda. Bikwiriye imyenda nk'imyenda y'akazi n'amarido.
3. Ibikoresho byo gukorana n'ibiribwa na pulasitiki: Bisphenol A substitute
Ibikoresho byo gupakira ibiribwa: Bisphenol S ikoreshwa mu gukora irangi rya epoxy resin ryo mu rwego rwo hejuru (nk'irangi ry'imbere mu macupa) na pulasitiki ikoreshwa mu biryo (nk'amacupa y'abana n'ibikoresho byo ku meza). Bitewe n'uko igenda gake, yubahiriza amahame agenga umutekano w'ibiryo nk'amabwiriza ya EU 10/2011 na China GB 4806.
Gusiga impapuro zishyushye: Nk'igisimbura BPA, ikoreshwa hamwe n'amabara ya leuco n'abakora amabara ku mpapuro zishyushye (nk'impapuro zo kubika amafaranga muri supermarket n'ibirango byo gutanga ibicuruzwa byihuse) kugira ngo hirindwe ko BPA yimukira mu mubiri w'umuntu binyuze mu gukora ku ruhu.
4. Izindi porogaramu
Imiti ikoreshwa mu gutera imiti: Bisphenol S ikoreshwa mu gutera imiti ifite ubushobozi bwo kurwanya ububyimbirwe no kurwanya indwara.
Ibikoresho bya Chemical Analytical: Bisphenol S ikoreshwa nk'ikimenyetso cya aside-base cyangwa ikintu gihuza ibintu mu gusesengura ingano ya iyoni z'icyuma (nk'icyuma n'umuringa). Itsinda rya phenolic hydroxyl rikora complex ihamye hamwe na iyoni z'icyuma, bigatuma habaho impinduka mu ibara.
Ubushyuhe bwinshi:Molekile ya Bisphenol S irimo amatsinda abiri ya phenolic hydroxyl n'itsinda rimwe rikomeye rya sulfone rikuramo electron (-SO ₂ -), bigatuma iba aside nyinshi kurusha fenoli zisanzwe.
Uburyo busanzwe bwo gukora ibintu bya phenolic:Amatsinda abiri ya phenolic hydroxyl muri molekile ya Bis (4-hydroxyphenyl) Sulfone afite reactivity nyinshi kandi ashobora guhura n'ingaruka zitandukanye za chemicals nko etherification, esterification, na polycondensation, urugero, agakora reaction na formaldehyde kugira ngo habeho resin.
Ubwirinzi bwiza:Bis (4-hydroxyphenyl) Sulfone ifite ubushobozi bwo kurwanya ubushyuhe, kurwanya ogisijeni ndetse no kudahinduka k'urumuri, ariko ishobora kwangirika bitewe n'aside ikomeye, alkali ikomeye cyangwa imiterere ikomeye ya ogisijeni.
Ubushyuhe bwinshi butuje:Ubushyuhe bwa Bisphenol S mu ihinduka ry'ubushyuhe buri hejuru ya 300℃, bigaragaza ko buhamye neza mu gihe cyo gutunganya ubushyuhe bwinshi
Uburozi buke:Bisphenol S ni ikintu kidahumanya cyane.
Bisphenol S ishobora gukoreshwa nk'ikintu gisimbura bisphenol A:Bitewe n’ingaruka zishobora guterwa na bisphenol A ku buzima, bisphenol S ishobora gukoreshwa nk'inyongera mu gukora ibikoresho byinshi bya molekile nka polycarbonate na epoxy resin, kandi ibikoresho byinshi bya molekile byakozwe bifite ubushobozi bwo guhagarara neza mu bushyuhe, kudahagarara neza mu binyabutabire ndetse n’ubushobozi bwo gukora.
