Uburyo bwo Gukoresha HydroxyPropyl methylcellse

HydroxyPropyl Methylcellsaliose (HPMC) ni selile itari ionic yakoreshejwe cyane mubikoresho byo kubaka, imiti, ibiryo, imiti ya buri munsi nibindi bice.

1. Ibiranga ishingiro
Gukemurwa: HPMC irashonje mumazi akonje hamwe nibibazo bya kama, kandi igisubizo cyacyo kidafite aho kibogamiye cyangwa ngo alkaline.
Kwinginga: HPMC ifite ubushobozi buhebuje kandi irashobora kunoza viscosiya na thixotropi yibikoresho.
Kugumana amazi: Birashobora kuramba neza igihe cyamazi no kunoza imikorere yubwubatsi.
Umutungo wa firime: HPMC irashobora gukora firime isobanutse kandi ihindagurika.
THERMORILATION: Bizasenya gushyushya ubushyuhe runaka hanyuma ugaruke muri leta yasheshwe nyuma yo gukonja.

2. Uburyo bwo Gukoresha
INTAMBWE
HPMC igomba gushonga neza mugihe ikoreshwa mugukina byuzuye kuruhare rwayo:
Gusenya amazi akonje:
Kunyanyagiza HPMC buhoro mumazi akonje kugirango wirinde gukusanya.
Ongeraho mugihe ushishikaye gukora uruvange rumwe.
Nyuma yo guhagarara mugihe runaka (iminota igera kuri 30 kumasaha menshi), HPMC izasenya buhoro buhoro kugirango ikore igisubizo cyiboneye.
Iseswa ryamazi ashyushye:
Kuvanga HPMC n'amazi ashyushye (hejuru ya 70 ° C) hanyuma ukangutsi kugirango uyasane.
Nyuma yo gukonja, ongeramo amazi akonje kandi ukomeze kubyutsa kugeza igihe yashonga rwose.
Ubu buryo burakwiriye kuri scenarios aho igisubizo kigomba gutegurwa vuba.

Kugenzura
Ukurikije imikoreshereze yihariye, kwibanda kubisubizo bya HPMC bigomba guhinduka neza:
Umwanya wubwubatsi: Mubisanzwe byateguwe nka 0.1% ~ 1% Igisubizo cyamazi, cyane cyane gikoreshwa mugushira, shyira ifu, titt, etc.
Umwanya wibiryo: Imikoreshereze isanzwe 0.05% ~ 0.5%, yiyemeje ukurikije amabwiriza yongerera uruhare.
Umwanya w'ubuvuzi: HPMC ni igiteranyo cyo kubibi biyobyabwenge, kandi amafaranga yiyongera agomba kugenzurwa kugirango habeho ingaruka zo kuzamura ibiyobyabwenge.

Koresha Amashanyarazi
Inganda zubwubatsi:
Muri Prowder ifu na minisiteri, ishonga bwa mbere hpmc mumazi, hanyuma uyivane neza nibindi bigize murwego rugereranijwe.
Iyo ikoreshwa muri tile ifatika, HPMC irashobora guteza imbere viscosiya no kurwanya imitungo.
Umurima wa farumasi:
Irashobora gukoreshwa mu buryo butaziguye ibisate bya farumasi kugirango utezimbere gusenyuka no kurekura imikorere yo kugenzura.
Umurima wa Imiti ya buri munsi:
Ikoreshwa nka Thickener cyangwa Emalifier stabilizer mubikoresho no mumasoko yo mumaso.
Umurima upara:
Ikoreshwa nka Thickener muri latex irangi kugirango wirinde imvura yijimye.
3. INTEGO
Ingaruka z'ubushyuhe: Kudakemurwa kwa HPMC bifitanye isano rya bugufi n'ubushyuhe. Ubushyuhe bwinshi bushobora gutera i pelation, bityo birasabwa gukorera mumazi akonje kugirango twirinde agglomeration ako kanya.
Uburyo bwo Gutesha agaciro: Gukangura gahoro kandi rwose kugirango wirinde ibibyimba bikabije biterwa no gukangura cyane.
Imiterere yo kubika:
Irinde guhura nibidukikije bitoroshye.
Irinde guhura na acide ikomeye, alkalis ikomeye cyangwa oxidants.
Umutekano: HPMC ntabwo ari uburozi kandi idashishikara, ariko ibikoresho byo gukingira bigomba kwambarwa mugihe cyo gukora ifu kugirango birinde guhumeka cyangwa guhura n'amaso.
Binyuze mu gusenya neza no gukoresha, hydroxyPropyl methylcellse irashobora gucuranga kubyimba, kugumana amazi, gukomera no kugira ingaruka mbi mumirima itandukanye.
