Mukushandiswa kwehydroxyprupyl methyl celluloseHpc, isu tinowanzoona kuti zvakakamurwa kuita marudzi maviri: nekukurumidza uye zvishoma nezvishoma kupaza. Ngatinzwisise mutsauko pakati pekukurumidza kupaza uye kupera simba kwehydroxypropropropropropyl methyl cellulose.
Instant HPMC inoreva kushandiswa kwekutambisa kwemuchinjiko wekurapa kwekurapa mukugadzira mumvura inotonhora, asi kwete mhinduro chaiyo, kuburikidza neyunifomu kusimuka, ndiko kuti, kupaza;
Slow solullable hpmc inogona zvakare kunzi inopisa melt zvigadzirwa. Kana mvura inotonhora inosangana, inogona kukurumidza kuparadzirwa mumvura inopisa. Nekumutsa zvisina kujairika, tembiricha yemhinduro ichadonha kune imwe tembiricha. .
Heino kusiyanisa pakati pemhinduro nekukurumidza uye mhinduro inononoka. Kana iwe uine chero mibvunzo nezve ruzivo urwu, iwe unogona zvakare kutiudza.
Hydroxyprusyl methyl cellelose hpmc kunonoka kwehystem hydration
Kuwedzera hydroxypropyl methyl cellelose kujekesa kunodzora hydration yayo. Saka chii chaunoziva nezve mashandiro azvo? Ngatitarisei hydroxyprupyl methyl cellulose kusvika kunonoka kusvibisa hydration. Nheyo.
1. Ion kufamba disorder hypothesis
Isu tinofungidzira kuti hydroxyprusyl methyl methyl cellowse vaizowedzera visikopa yemari mhinduro, dzinotadzisa huwandu hweIonic Movement, uye kunonoka hydration yeiyo simende. Nekudaro, iyo yakaderera viscosity cellulose anaiters mumuedzo uyu aive nekugona kusimba kwekunonoka kwehystem hydration. Naizvozvo, kufungidzirwa uku hakuna basa. Pourchez et al. Zvakare kusahadzika uku hypothesis. Muchokwadi, iyo nguva yeIon kutama kana kutama ipfupi, sezviri pachena kwete kusaenzana nekunonoka kweiyo coment hydration.
2. Alkaline kusvibiswa
Polysacsersides nyore nyore degrade pasi peAlkaline mamiriro ekugadzira hydroxyl carboxyl acids iyo inonoka cydration hydration. Naizvozvo, iyo yakanonoka hydroxyprusypropyl methyl celler inogona kunge iri nekuda kwekusvibiswa kwayo muAlkaline coment slument kuumba hydroxycarboycarboycar. Nekudaro, pourchez et al. Wakawana kuti cellulose ana ana manyorerwo aive akagadzikana pasi pemamiriro ezvinhu eAlkaline, akasvibiswa zvishoma, uye zvigadzirwa zvekushambadzira zvakave nemhedzisiro zvishoma pakunonoka kweiyo hydration.
3, kushambadzira
Adsorption inogona kuve yeHydroxyPropyl methyl cellows cellows cellyl Pourchez et al. Akawana kuti ma cellulose ether adsorbled pane nzvimbo dze hydration zvigadzirwa zvakadai secalcium hydroxide, clcium aluminate hydrate, asi kwete nyore kudhiraivha neyettringe uye isina kugadzirwa zvikamu. Uyezve, mune iyo cellulose ether, iyo adsorption kugona kwehec yakasimba kupfuura iyo yekuzvimba mc. Iyo yakadzika zvirimo zvehydroxytHyl muHec kana hydroxypropyl, iyo yakasimba yekushambadzira, seyakagadzirwa hydration yeCalcium Hydroxide yakasimba kupfuura iyo yeCSS. Kuwedzera kuongororwa kunoratidzawo kuti kuwanda kweiyo hydration zvigadzirwa uye cellulose ether inoenderana nekunonoka kweiyo hydration: Cellulose ethy of triccium Silcecuum uye maHydration zvigadzirwa zvine simba kwazvo Kunonoka siltirate hydration yakaenderera mberi.
Izvi ndezve hydroxyprupyl methyl cellelose kunonoka coment hydration nheyo. Tinovimba kuti ruzivo urwu rwunogonesa kuti munhu wese anzwisise kuti chigadzirwa chinoshanda sei uye chishandise zviri nani.
