Hydroxyethyl Methyl Cellulose (HEMC) Gwajin Zazzabi na Gel

Gwajin zafin gel na Hydroxyethyl Methyl Cellulose (HEMC) ya haɗa da ƙayyade yawan zafin jiki wanda maganin HEMC ke ɗaukar gelation ko samar da daidaiton gel-kamar. Wannan kadarar tana da mahimmanci a aikace-aikace daban-daban, gami da magunguna, kayan kwalliya, da kayan gini. Anan ga yadda zaku iya gudanar da gwajin zafin gel na HEMC:

Abubuwan da ake buƙata:

1. HEMC foda
2. Ruwan distilled ko sauran ƙarfi (ya dace da aikace-aikacen ku)
3. Tushen zafi (misali, wankan ruwa, farantin zafi)
4. Thermometer
5. Sarrafa sanda ko maganadisu mai motsi
6. Beakers ko kwantena don hadawa

Tsari:

1. Shirya jerin mafita na HEMC tare da ƙididdiga daban-daban (misali, 1%, 2%, 3%, da dai sauransu) a cikin ruwa mai narkewa ko sauran abubuwan da kuka zaɓa. Tabbatar cewa an tarwatsa foda na HEMC sosai a cikin ruwa don hana clumping.
2. Sanya daya daga cikin mafita a cikin kwali ko akwati, sannan a nutsar da ma'aunin zafi da sanyio a cikin maganin don lura da yanayin zafi.
3. Zafafa maganin a hankali ta amfani da wanka na ruwa ko farantin zafi yayin motsawa akai-akai don tabbatar da dumama iri ɗaya da haɗuwa.
4. Saka idanu da bayani a hankali kuma lura da kowane canje-canje a cikin danko ko daidaito yayin da zafin jiki ke ƙaruwa.
5. Yi rikodin yawan zafin jiki wanda bayani ya fara girma ko samar da daidaiton gel-kamar. An san wannan zafin jiki da zafin jiki na gel ko gelation na maganin HEMC.
6. Maimaita tsari don kowane maida hankali na HEMC bayani don ƙayyade yawan zafin jiki na gel a cikin kewayon yawa.
7. Bincika bayanan don gano kowane yanayi ko alaƙa tsakanin tattarawar HEMC da zafin gel.
8. Zabi, yi ƙarin gwaje-gwaje ko gwaje-gwaje don kimanta tasirin abubuwan kamar pH, maida hankali na gishiri, ko ƙari akan zafin gel na mafita na HEMC.

Nasihu:

• Tabbatar cewa an tarwatsa foda na HEMC a cikin ruwa don hana kullun ko gelation mara kyau.
• Yi amfani da distilled ruwa ko abin da ya dace don shirya hanyoyin HEMC don guje wa tsangwama daga ƙazanta ko gurɓatawa.
• Ci gaba da jujjuya maganin yayin dumama don kula da rarraba yanayin zafi iri ɗaya da haɗuwa.
• Ɗauki ma'auni da yawa da matsakaicin sakamako don inganta daidaito da aminci.
• Yi la'akari da ƙayyadaddun buƙatun aikace-aikacenku lokacin zabar abubuwan tattarawa na HEMC da yanayin gwaji.

Ta bin wannan hanya, za ku iya ƙayyade zafin gel na Hydroxyethyl Methyl Cellulose (HEMC) mafita kuma ku sami mahimman bayanai game da kaddarorin rheological da halayensa a ƙarƙashin yanayi daban-daban.
