Te rereketanga i waenga i te HPMC me te methylcellulose

Ko te HPMC (Hydroxypropyl methylcellulose) me te methylcellulose e whakamahia nuitia ana i roto i nga umanga kai, rongoa, me nga umanga tiaki whaiaro ano he mea whakamaroke, hei whakapumau, hei whakaemulsifier, hei here. Ahakoa he rite tonu o raatau, he rereke etahi i waenga i te HPMC me te methylcellulose:

1. Hanganga matū: Ko te HPMC me te methylcellulose i ahu mai i te cellulose, he polysaccharide taiao. Ko te HPMC he cellulose kua whakarereketia, kua whakakapia etahi o nga roopu hydroxyl i runga i te ngota ngota cellulose ki nga roopu hydroxypropyl. Ko te Methylcellulose he cellulose kua whakarereketia, i reira kua whakakapia etahi o nga roopu hydroxyl i runga i te ngota ngota cellulose ki nga roopu methyl.
2. Wairewa: Ko te HPMC he wairewa ake ki te wai i te methylcellulose, he maamaa ake te rewa me te whakamahi i roto i nga waihanga.
3. Viscosity: He teitei ake te pokey o te HPMC i te methylcellulose, ko te tikanga he pai ake te ahua o te ahua o te matotoru, a ka taea e ia te hanga i te riterite matotoru i roto i nga hanganga.
4. Whakawhana: Kei a Methylcellulose te kaha ki te hanga i te reera ka whakamahana ka whakamatao, karekau tenei taonga a HPMC.
5. Utu: He nui ake te utu o te HPMC i te methylcellulose.

I te katoa, ko te whiriwhiri i waenga i te HPMC me te methylcellulose ka whakawhirinaki ki te tono motuhake me nga ahuatanga e hiahiatia ana o te hanga. He pai ake pea te HPMC mo tana whakarewatanga me te riterite matotoru, engari ko te methylcellulose he pai ake mo tona kaha ki te hanga i nga ra.
