Abubuwan da ke cikin Hydroxypropoxy: Yawanci tsakanin 4.0% da 12.0%.
4. Abubuwan Danshi
Ana sarrafa yawan danshi na HPMC a ≤5.0%. Yawan danshi zai shafi daidaito da tasirin amfani da samfurin.
5. Abubuwan da ke cikin Toka
Toka ita ce ragowar da aka samu bayan an ƙone HPMC, galibi daga gishirin da ba na halitta ba da ake amfani da shi a tsarin samarwa. Yawanci ana sarrafa yawan tokar a ≤1.0%. Yawan tokar da ke cikinta na iya shafar bayyana da tsarkin HPMC.
6. Narkewa da bayyanawa
HPMC yana da kyau wajen narkewar ruwa kuma yana iya narkewa cikin sauri a cikin ruwan sanyi don samar da maganin colloidal iri ɗaya. Bayyanar maganin ya dogara ne akan tsarkin HPMC da tsarin narkewarsa. Maganin HPMC mai inganci yawanci yana da haske ko ɗan ɗanɗano madara.
7. Zafin Gel
Maganin ruwa na HPMC zai samar da gel a wani zafin jiki. Yawan zafin gel ɗinsa yawanci yana tsakanin 50 zuwa 90°C, ya danganta da yawan sinadarin methoxy da hydroxypropoxy. HPMC mai ƙarancin sinadarin methoxy yana da yawan zafin gel, yayin da HPMC mai yawan sinadarin hydroxypropoxy yana da ƙarancin zafin gel.
8. ƙimar pH
Darajar pH na maganin ruwa na AnxinCel®HPMC yawanci yana tsakanin 5.0 da 8.0, wanda yake tsaka-tsaki ko kuma alkaline mai rauni kuma ya dace da yanayi daban-daban na amfani.
9. Girman Ƙwayoyin Cuku
Mafi kyawun HPMC gabaɗaya ana bayyana shi azaman kashi da ke wucewa ta allon raga mai 80 ko 100. Yawanci ana buƙatar ≥98% ya ratsa ta allon raga mai 80 don tabbatar da cewa yana da kyakkyawan watsewa da narkewa lokacin amfani.
10. Abubuwan ƙarfe masu nauyi
Dole ne sinadarin ƙarfe mai nauyi (kamar gubar da arsenic) na HPMC ya bi ƙa'idodin masana'antu masu dacewa. Yawanci, sinadarin gubar yana ≤10 ppm kuma sinadarin arsenic yana ≤3 ppm. Musamman a fannin abinci da magunguna na HPMC, buƙatun sinadarin ƙarfe mai nauyi sun fi tsauri.
11. Alamomin ƙwayoyin cuta
Don maganin AnxinCel®HPMC da kuma abinci mai inganci, dole ne a kula da gurɓatar ƙwayoyin cuta, gami da jimlar adadin ƙwayoyin cuta, mold, yisti, E. coli, da sauransu, waɗanda galibi suna buƙatar:
Jimlar adadin tarin ≤1000 CFU/g
Jimlar adadin mold da yis ≤100 CFU/g
Ba dole ba ne a gano E. coli, Salmonella, da sauransu.
12. Manyan wuraren amfani
Ana amfani da HPMC sosai a masana'antu da yawa saboda kauri, riƙe ruwa, samar da fim, shafawa, emulsification da sauran kaddarorinsa:
Masana'antar gini: A matsayin mai kauri da kuma mai riƙe ruwa a turmi na siminti, foda na putty, manne na tayal, da kuma rufin ruwa don inganta aikin gini.
Masana'antar harhada magunguna: Ana amfani da shi azaman kayan mannewa, mai dorewa, da kuma kayan da aka yi amfani da su wajen samar da ƙwayoyin magani.
Masana'antar abinci: ana amfani da shi azaman emulsifier, stabilizer, thickener, ana amfani da shi a cikin jelly, abubuwan sha, kayan gasa, da sauransu.
Masana'antar sinadarai ta yau da kullun: ana amfani da ita azaman mai kauri da mai daidaita emulsifier a cikin kayayyakin kula da fata, sabulun wanki, da shamfu.
Manuniyar fasaha taHPMCsun haɗa da danko, matakin maye gurbin (abun da aka yi amfani da shi a cikin rukuni), danshi, abun ciki na toka, ƙimar pH, zafin gel, ƙanƙanta, abun ciki na ƙarfe mai nauyi, da sauransu. Waɗannan alamun suna ƙayyade aikin aikace-aikacensa a fannoni daban-daban. Lokacin zabar HPMC, masu amfani ya kamata su ƙayyade ƙayyadaddun bayanai masu dacewa bisa ga takamaiman buƙatun aikace-aikacen don tabbatar da mafi kyawun tasirin amfani.
