Gabatarwar Samfurin CMC don Manna Buga Mai Aiki

1. Sodium Carboxymethyl Cellulose
Manna bugu mai amsawa wani tsari ne tare da tsarin ether wanda aka samu ta hanyar gyaran sinadarai na cellulose na halitta.Ita ce manne mai narkewa da ruwa wanda za'a iya narkar da shi cikin ruwan sanyi da ruwan zafi.Maganin sa na ruwa mai ruwa yana da ayyuka na haɗin gwiwa, thickening, tarwatsawa, dakatarwa da ƙarfafawa.

Reactive bugu manna samfur ne na sodium carboxymethyl cellulose tare da wani babban mataki na etherification.Tsarin na musamman ya sa rukunin hydroxyl ɗinsa na farko ya maye gurbinsa gaba ɗaya, don guje wa amsawa tare da rini mai amsawa.

A matsayin thickener na bugu manna, reactive bugu manna iya daidaita danko, inganta fluidity na manna, inganta hydrophilic ikon rini, sa rini uniform da kuma rage launi bambanci;a lokaci guda, a cikin aikin wankewa bayan bugu da rini, yawan wankewa ya fi girma, Yarinyar yana jin taushi ga taɓawa.

2. Kwatanta halaye na reactive bugu manna da sodium alginate
2.1 Manna ƙimar

Idan aka kwatanta da sodium alginate, reactive bugu manna yana da mafi girma danko, ko ana amfani da shi kadai ko a hade tare da sauran thickeners, zai iya yadda ya kamata rage farashin manna;Yawancin lokaci, manna bugu mai aiki The sashi shine kawai 60-65% na sodium alginate.

2.2 Yawan amfanin launi da ji

Samuwar launi na manna bugu da aka shirya tare da manna bugu mai amsawa kamar yadda mai kauri yayi daidai da na sodium alginate, kuma masana'anta suna jin laushi bayan yankewa, wanda yayi daidai da na samfuran manna na sodium alginate.

2.3 Manna kwanciyar hankali

Sodium alginate colloid ne na halitta, wanda ke da rashin haƙuri ga ƙananan ƙwayoyin cuta, ɗan gajeren lokacin ajiya na manna launi, kuma yana da sauƙin lalacewa.Zaman lafiyar samfuran sodium carboxymethyl cellulose na yau da kullun ya fi na sodium alginate.Reactive bugu manna kayayyakin an inganta ta musamman tsari, da kuma electrolyte juriya ne mafi alhẽri daga talakawa sodium carboxymethyl cellulose kayayyakin.A lokaci guda kuma, suna da dacewa mai kyau tare da kayan taimako na sinadarai da rini, kuma ba su da sauƙi a lalata da lalacewa yayin ajiya.Kwanciyar hankali yana da kyau fiye da sodium alginate.

2.4 Rheology (madaidaicin)

Dukansu sodium alginate da CMC sune ruwan ruwa na pseudoplastic, amma sodium alginate yana da ƙarancin tsarin danko da ƙimar PVI mai girma, don haka bai dace da bugu na allo na zagaye (lebur) ba, musamman bugu na allo mai tsayi;Samfuran bugu mai amsawa suna da girman tsarin danko, ƙimar PVI kusan 0.5, mai sauƙin buga alamu da layi.Haɗin sodium alginate da manna bugu mai aiki na iya saduwa da ƙarin buƙatun rheological na manna bugu
