Hydroxypropyl ibinyamisogwe ether-HPS

Hydroxypropyl krahisi ether (HPS) ni imiti ikomoka ku miti ihindura imiti isanga ikoreshwa cyane mu nganda zitandukanye kubera imiterere yihariye. Uru ruganda ruboneka mugukora ibinyamisogwe hamwe na oxyde ya propylene, biganisha ku gusimbuza amatsinda ya hydroxyl muri molekile ya krahisi hamwe na hydroxypropyl. Ibicuruzwa bivamo byerekana imbaraga zo gukama kwamazi, gutuza, kwiyegeranya, hamwe no gukora firime ugereranije na krahisi kavukire.

1.Imiterere n'imiterere:

Hydroxypropyl krahisi ether ifite imiterere igoye ituruka ku guhindura molekile ya krahisi. Ibinyamisogwe ni polysaccharide igizwe na glucose ibice bifitanye isano na glycosidic. Inzira ya hydroxypropylation ikubiyemo gusimbuza amatsinda ya hydroxyl (-OH) muri molekile ya krahisi hamwe na hydroxypropyl matsinda (-OCH2CHOHCH3). Ihinduka rihindura imiterere yumubiri na chimique ya krahisi, itanga imiterere myiza.

Urwego rwo gusimbuza (DS) ni ikintu cyingenzi kigena urugero rwa hydroxypropylation. Yerekana impuzandengo ya hydroxypropyl matsinda yometse kuri buri glucose muri molekile ya krahisi. Indangagaciro za DS zerekana urwego runini rwo guhindura, biganisha ku mpinduka zikomeye mumiterere ya krahisi.

2.Hydroxypropyl krahisi ether yerekana ibintu byinshi byifuzwa:

Amazi meza: HPS yerekana imbaraga ziyongera mumazi ugereranije na krahisi kavukire, bigatuma ikenerwa mubikorwa bitandukanye aho bikenewe gushingira kumazi.

Viscosity: Kubaho kwitsinda rya hydroxypropyl ritanga ubwiyongere bwibisubizo bya HPS, ibyo bikaba byiza mugukoresha umubyimba nko mubifata, ibifuniko, nibikoresho byubwubatsi.

Ubushobozi bwo gukora firime: HPS irashobora gukora firime zoroshye kandi zibonerana mugihe zumye, zitanga inzitizi hamwe nubushyuhe bwamazi. Uyu mutungo ufite agaciro mubisabwa nka firime ziribwa, impuzu, nibikoresho byo gupakira.

Igihagararo: Hydroxypropyl krahisi ether yerekana umutekano muke kurwanya ubushyuhe, kogosha, no kwangirika kwimiti ugereranije na krahisi kavukire, ikagura akamaro kayo mubidukikije no mubikorwa bitandukanye.

Guhuza: HPS irahujwe nubwoko butandukanye bwinyongera, polymers, nibindi bikoresho, bigafasha kuyikoresha mubihimbano hamwe nibihimbano bigoye.

3.Ibisabwa:

Hydroxypropyl starch ether isanga porogaramu nini mubikorwa bitandukanye bitewe nuburyo butandukanye. Bimwe mubyingenzi byingenzi birimo:

Ibikoresho byubwubatsi: HPS ikoreshwa nkumuhinduzi wa rheologiya, umubyimba, hamwe nogukoresha amazi mubicuruzwa bishingiye kuri sima, plastike ya gypsumu, ibyuma bifata amabati, na minisiteri. Itezimbere imikorere, gufatana, hamwe nubukanishi bwibikoresho.

Ibiribwa n'ibinyobwa: Mu nganda y'ibiribwa, HPS ikoreshwa nka stabilisateur, ikabyimbye, hamwe n’inyandiko mu bicuruzwa nk'isupu, isosi, ibiryo by'amata, n'ibirungo. Itezimbere umunwa, guhuzagurika, no gutekana neza bitagize ingaruka kuburyohe cyangwa umunuko.

Imiti ya farumasi: Hydroxypropyl krahisi ether ikoreshwa muburyo bwa farumasi nkibikoresho, bidahuza, kandi bigenzurwa-kurekura mu gukora ibinini. Yorohereza ibinini bya tablet, iteza imbere imiti imwe, kandi inoze kubahiriza abarwayi.

Ibicuruzwa byita ku muntu ku giti cye: HPS yinjizwa mu mavuta yo kwisiga, ubwiherero, n’ibicuruzwa byita ku muntu nkibyimbye, emulisiferi, na firime yahoze. Itezimbere ibicuruzwa, ituze, nibiranga ibyiyumvo muburyo bwa cream, amavuta yo kwisiga, nibicuruzwa byita kumisatsi.

Impapuro n’imyenda: Mu nganda zimpapuro, HPS ikoreshwa nkubunini buringaniye, guhuza ibifuniko, hamwe no kongera imbaraga kugirango ubuziranenge bwimpapuro, bicapwe, nimbaraga. Mu myenda, ikoreshwa nkigikoresho kinini kugirango itange ubukana no koroshya imyenda.

4.Inyungu:

Imikoreshereze ya hydroxypropyl starch ether itanga inyungu nyinshi kubabikora, abayikora, hamwe nabakoresha-nyuma:

Kunoza imikorere: HPS itezimbere imikorere yibicuruzwa bitandukanye itanga imitungo yifuzwa nko kugenzura ibicucu, gutuza, gufatira hamwe, no gukora firime.

Guhinduranya: Guhuza nibindi bikoresho nibikoresho bituma habaho uburyo butandukanye mu nganda nyinshi, bigafasha iterambere ryibicuruzwa bishya.

Ikiguzi-Cyiza: Nubwo cyongerewe imbaraga, HPS itanga ibisubizo byigiciro ugereranije nibindi byongeweho cyangwa ibiyigize, bigira uruhare mukuzigama muri rusange.

Kubahiriza amabwiriza: HPS yujuje ibipimo ngenderwaho byumutekano, ubuziranenge, hamwe n’ibidukikije, byemeza kubahiriza amabwiriza n’ibipimo ngenderwaho mu turere dutandukanye.

Kuramba: Inkomoko ishingiye kuri krahisi nka HPS ikomoka kubutunzi bushobora kuvugururwa, bigatuma ubundi buryo bwangiza ibidukikije kuri

ibikomoka kuri peteroli. Ibinyabuzima byabo bigira uruhare runini mubikorwa birambye.

hydroxypropyl krah ether (HPS) nibintu byinshi kandi bifite agaciro hamwe nibikorwa bitandukanye mubikorwa bitandukanye kuva mubwubatsi, ibiryo, imiti nubuvuzi bwihariye. Imiterere yihariye, harimo kongera imbaraga zo gukemuka, kwiyegeranya, gutuza, hamwe nubushobozi bwo gukora firime, bituma iba ikintu cyingirakamaro muburyo bwinshi. Mugihe inganda zikomeje gushakisha ibintu birambye kandi bikora neza, ibyifuzo bya HPS biteganijwe kwiyongera, bigatera imbere guhanga udushya no gushyira mubikorwa ejo hazaza.
