Imiti ya buri munsi hydroxypropyl methyl selulose

Icyiciro cya chimique hydroxypropyl methyl selulose ya buri munsi ni polymer synthique yateguwe no guhindura imiti ya selile isanzwe nkibikoresho fatizo. Ether ya selulose ni inkomoko ya selile naturel, umusaruro wa selile ya selile na polymer synthique iratandukanye, ibikoresho byayo byibanze ni selile, uruganda rwa polymer rusanzwe. Kubera umwihariko wimiterere ya selile karemano, selile ubwayo ntabwo ifite ubushobozi bwo kubyitwaramo na etherifyinging. Ariko, nyuma yo kuvura imiti yabyimbye, imiyoboro ikomeye ya hydrogène hagati yiminyururu ya molekile irasenyuka, kandi ibikorwa byitsinda rya hydroxyl birekurwa muri selile ya alkali ifite ubushobozi bwo gukora. Nyuma yimyitwarire ya etherifying agent, itsinda -OH rihindurwa -OR itsinda kugirango babone selile ya ether.

Icyiciro cya chimique ya buri munsi idasanzwe ibihumbi 200 bya viscosity ako kanya hydroxypropyl methyl selulose ni ifu yera cyangwa yumuhondo gake, kandi idafite impumuro nziza, uburyohe, ntabwo ari uburozi. Gukemura mu ruvange rw'amazi akonje hamwe n'umuti ukungahaye kugirango ube igisubizo kibonerana. Igisubizo cyamazi gifite ibikorwa byubuso, gukorera mu mucyo mwinshi, gutuza gukomeye, gukomera mumazi ntabwo byatewe na pH. Ingaruka zibyibushye na antifreeze muri shampoo no koza umubiri, kubika amazi no gukora firime nziza kumisatsi nuruhu. Hamwe n'ubwiyongere bukabije bwibikoresho fatizo, selile (antifreeze thickener) irashobora gukoreshwa muri shampoo no koza umubiri birashobora kugabanya cyane ikiguzi no kugera kubisubizo byifuzwa.

1. Ibiranga ibyiza nibyiza bya selile ya buri munsi ya selile HPMC:

1, kurakara gake, ubushyuhe bwinshi nigitsina;

2, intera nini ya pH itajegajega, muri pH agaciro ka 3-11 irashobora kwemeza ituze ryayo;

3. Kongera gushimangira gushyira mu gaciro;

4. Ongera ububobere, uhagarike igituba, utezimbere uruhu;

5. Kunoza neza imikorere ya sisitemu.

Imiti ya buri munsi ya selile selile HPMC igipimo cyo gusaba:

Ikoreshwa muri shampoo, gukaraba umubiri, gusukura mu maso, amavuta yo kwisiga, cream, gel, toner, kondereti, ibicuruzwa bikora, umuti wamenyo, amazi, igikinisho cyamazi menshi.

3 Uruhare rwimiti ya buri munsi ya selile HPMC:

Mugukoresha amavuta yo kwisiga, akoreshwa cyane cyane mubyimbye, kubira ifuro, emulisation ihamye, gutatanya, gufatira hamwe, gukora firime no kunoza imikorere yo gufata neza amazi, ibicuruzwa byijimye cyane bikoreshwa nkibyimbye, ibicuruzwa bito cyane bikoreshwa cyane cyane nko gukwirakwiza no guhagarika firime. .

Imiti 4 ya buri munsi ya selile ya selile HPMC:

Hydroxypropyl methyl fibre kugirango ihuze nubwiza bwinganda zimiti ni ibihumbi 100, ibihumbi 150, ibihumbi 200, ukurikije formulaire yabo yo guhitamo ingano yongewe mubicuruzwa muri rusange ni ibihumbi bitatu kugeza kuri bitanu.
