Imikoreshereze ya PG

1. Ibikoresho fatizo bya resin, plasticizers, surfactants, emulsifiers, na emulsifiers nabyo bishobora gukoreshwa nk'ibirwanya gukonjesha no gutwara ubushyuhe
2. Ku bijyanye na chromatography ya gaze phase, solvent, antikonjesha, plasticizer na dehydration agent
3. Ifu y'inguzanyo; ifu igabanya ubushyuhe; igabanya ubushyuhe; irwanya ubushyuhe; irwanya udukoko; igabanya ubushyuhe; igabanya ubushyuhe; igabanya ubushyuhe; igabanya ubushyuhe; igabanya ubushyuhe; igabanya ubushyuhe; igabanya ubushyuhe; igabanya ubushyuhe. GB2760 ~ 96 igaragara nk'inyongera mu gutunganya ibiryo. Ikoreshwa cyane cyane mu gukuramo ibirungo bitandukanye, amarangi, imiti irinda ubushyuhe, n'ibishyimbo bya vanilla, imbuto za kawa zikaranze, n'ibirungo karemano. Ishobora kandi gukoreshwa nk'inyongera mu kwirinda ubushyuhe mu mafunguro no mu gusya. Kongeramo 0.006% ku mata ya soya bishobora gutuma uburyohe budahinduka mu gihe cyo gushyushya. Ikorwamo tofu zera kandi irabagirana, kandi gukaranga byongera ubwinshi.
4. Ingurube -glycol ni yo igize germine benzazole.
5. Nk'umusemburo, ibintu bibungabunga, amarangi, antioxydants n'ibindi biryo bigora gushonga mu mazi nk'amazi bishongeshwa mu mazi, hanyuma bikongerwa mu biryo; bifite ubushobozi bwo kuyungurura cyane kandi bikagira ingaruka zo guhumeka no gukonjesha ibiryo. Amategeko agenga igihugu cyanjye ashobora gukoreshwa mu guteka, ku gipimo ntarengwa cya 3.0g/kg.
6. Pateyl glycol ni ingenzi mu bikoresho fatizo bya polyester idafite amazi, epoxy resin, na polyurethane resin. Ingano y'aka gace ingana na 45% by'ikoreshwa ryose rya propylene glycol. Iyi polyester idafite amazi ni nini cyane mu gusiga hejuru no mu gusiga pulasitiki. Ubukana n'ubushyuhe bya propylene glycol ni uburozi bukabije. Kubwibyo, ikoreshwa cyane mu nganda z'ibiribwa, imiti n'ubwiza nk'ibintu bitosesha, birwanya gukonjesha, amavuta n'ibinyabutabire. Mu nganda z'ibiribwa, propylene glycol na aside fatty bikora kugira ngo bikore aside fatty ya propylene glycol. Chemicalbook ikoreshwa cyane nk'imvange y'ibiryo; propylene glycol ni umuti mwiza cyane w'ibirungo n'amabara. Pigbolly ikunze gukoreshwa nk'umuti ugabanya ubushyuhe, woroshya, na gumin mu gukora ubwoko butandukanye bw'amavuta, amavuta, na glycrastasus mu nganda zikora imiti. Kubera ko propylene glycol ifite ubushobozi bwo gushonga neza hamwe n'ubwoko butandukanye bw'ibirungo, ikoreshwa kandi nk'umuti ugabanya ubushyuhe n'ibinyabutabire mu kwisiga. Pigbolly ikoreshwa kandi nk'umusemburo w'ibintu bihumanya itabi, ibikoresho birwanya ibumba, ibikoresho bitunganya amavuta yo kwisiga n'iwino igaragaza ibiribwa. Umuti wa propylene glycol ni umuti urinda gukonjesha.
7. Nk'umucuruzi w'imiti, umucuruzi w'imiti ugizwe n'udukoko. Ishobora gukoreshwa nk'umuti ugabanya ubushyuhe mu mavuta yo kwisiga, ibintu bigabanya ubushyuhe, ibintu bigabanya ubushyuhe, n'ibindi. Inganda z'itabi zishobora gukoreshwa nk'umwotsi, ibintu bigabanya ubushyuhe mu itabi, ibintu bibungabunga ubushyuhe, nibindi. Inganda z'ibiribwa zikoreshwa nk'impumuro nziza, ibintu bigabanya ubushyuhe biribwa, ibintu bifasha mu gupakira ibiryo bya Chemicalbook, ibintu birwanya kole, nibindi. Ishobora kandi gukoreshwa mu gukora resine za polyester zitarazura, kimwe n'ibintu bitera pulasitiki, ibintu bigabanya ubushyuhe, ibintu bifasha mu gusukura, ibintu bifasha mu gukurura ubushyuhe, nibindi. Ishobora kandi gukoreshwa mu nganda nka irangi, imiti yica udukoko, irangi n'izindi nganda.
8. Gukuraho indege, ibikoresho bikonjesha n'ibikonjesha, ibiryo n'ibirungo, ibikoresho bihumura neza, amavuta yo kwisiga n'ibikomoka ku buzima bw'umuntu ku giti cye, uburyo bwo kohereza ubushyuhe, amazi y'amazi n'ay'iferi, irangi n'ibisigazwa, ibiryo by'amatungo/ibiryo by'amatungo, imiti, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, resine ya polyester idafite amazi.
9. Gushonga, gukora ibintu bikomoka ku bimera, kurwanya gukonjesha, gukoresha pulasitiki, gukoresha imiti yica udukoko. Ibipimo ngenderwaho byo gusesengura chromatography ya gaz. Gupima chromatography ya gaz (ubushyuhe ntarengwa bwa 150 ° C, solvent ni chloroform), isesengura rya alcool, ester na ketone, nibindi.

Copylene glycol irashonga neza, ifite uburozi buke kandi irashya. Ikoreshwa cyane mu gutera (nk'inkongoro, gutera imitsi mu mitsi) n'imiti idaterwa (nk'umuti wo mu kanwa, guterwa amaso, amatwi, imiti yo guterwa amenyo, igitsina cy'umugore cyo mu nda, igitsina cy'umugore cyo mu nda. Soluks, ibikomoka ku bimera n'imiti irinda amenyo, imiti ibonerana, nibindi) ni imiti myiza kurusha glycerin, ishobora gushonga ibintu byinshi nka corticosterol (imisemburo y'igitsina), chloramphenicol, imiti ya sulfa, aside ya Barbich Umunyu, Liserin, quininine, aside asetiki dehumidone, aside sulfuriki, azote hydrochloride, vitamine A, vitamine D, amavuta menshi ahinduka, alkaloids nyinshi n'imiti myinshi ikomeye. Nk'umuti urinda bagiteri usa na ethanol, ingaruka zo gukumira imyumbati zisa na glycerol, iri hasi gato ya ethanol. Ibikoresho bya CHICALBOOK bikunze gukoreshwa nk'ibikoresho byo gusiga icyuma gito. Umuti uvanze n'amazi ushobora gutinza hydrolysis y'imiti imwe n'imwe no kongera ubuziranenge bw'ibicuruzwa. 15% kugeza kuri 30% by'umuti wa propylene hamwe na daisy isanzwe ishobora gukoreshwa nk'imiti irinda indwara zandura. Hafi 15% by'imiti ikoreshwa muri proprial dibol ishobora gukoreshwa nk'umuti utera ubushyuhe, 10% kugeza kuri 30% by'umuti wa propylene glycol gas fog solvent, 10% ~ 25% by'umuti wa propylene glycol wo kunywa, 10% kugeza kuri 60% by'imiti iterwa, 5% kugeza kuri 80% by'umuti ukoreshwa muri iyo miti bigomba gukoreshwa nk'imiti igabanya ubushyuhe n'imiti isanzwe.
