Kugwiritsa ntchito sodium carboxymethyl cellulose ndi hydroxyethyl cellulose pazamankhwala atsiku ndi tsiku

Carboxymethylcellulose sodium (CMC-Na) ndi chinthu chachilengedwe, chochokera ku carboxymethylated mu cellulose, komanso chingamu chofunikira kwambiri cha ionic cellulose.Sodium carboxymethyl cellulose nthawi zambiri ndi anionic polima pawiri yokonzedwa ndi kuchitapo kanthu pa cellulose yachilengedwe yokhala ndi caustic alkali ndi monochloroacetic acid, yokhala ndi kulemera kwa ma cell kuyambira masauzande angapo mpaka mamiliyoni.CMC-Na ndi ulusi woyera kapena granular ufa, wopanda fungo, wosakoma, hygroscopic, yosavuta kumwazikana m'madzi kupanga mandala colloidal yankho.

Ngati ndale kapena zamchere, yankho lake ndi lamadzimadzi apamwamba kwambiri.Kukhazikika kwa mankhwala, kuwala ndi kutentha.Komabe, kutentha kumangokhala 80°C, ndipo ngati yatenthedwa kwa nthawi yayitali kuposa 80°C, mamasukidwe akayendedwe adzachepa ndipo adzakhala insoluble m'madzi.

Sodium carboxymethyl cellulose ndi mtundu wa thickener.Chifukwa cha ntchito zake zabwino, zakhala zikugwiritsidwa ntchito kwambiri m'makampani azakudya, komanso zalimbikitsa chitukuko chachangu komanso chathanzi chamakampani azakudya kumlingo wina.Mwachitsanzo, chifukwa zina thickening ndi emulsifying zotsatira, angagwiritsidwe ntchito kukhazikika yogurt zakumwa ndi kuonjezera mamasukidwe akayendedwe a yogurt dongosolo;chifukwa cha zinthu zina za hydrophilicity ndi kubwezeretsanso madzi m'thupi, zitha kugwiritsidwa ntchito kukonza madyedwe a pasitala monga mkate ndi mkate wowotcha.khalidwe, kutalikitsa alumali moyo wa pasitala mankhwala ndi kuonjezera kukoma.

Chifukwa chakuti ali ndi zotsatira za gel osakaniza, ndizopindulitsa kwa chakudya kuti apange gel osakaniza bwino, kotero angagwiritsidwe ntchito kupanga odzola ndi kupanikizana;Itha kugwiritsidwanso ntchito ngati chophikira chodyera, chophatikizidwa ndi zokhuthala zina, ndikufalikira Pamalo ena azakudya, zimatha kusunga chakudyacho mokulirapo, ndipo chifukwa ndi zinthu zodyedwa, sizingabweretse mavuto pamunthu. thanzi.Chifukwa chake, CMC-Na ya kalasi yazakudya, monga chowonjezera chabwino chazakudya, imagwiritsidwa ntchito kwambiri popanga zakudya m'makampani azakudya.

Hydroxyethylcellulose (HEC), chemical formula (C2H6O2)n, ndi yoyera kapena yopepuka yachikasu, yopanda fungo, yopanda poizoni kapena yolimba, yopangidwa ndi cellulose yamchere ndi ethylene oxide (kapena chlorohydrin) Yokonzedwa ndi etherification reaction, ndi ya non- ma ionic soluble cellulose ethers.Chifukwa HEC ili ndi katundu wabwino wa thickening, kuyimitsa, kubalalika, emulsifying, kumanga, kupanga mafilimu, kuteteza chinyezi ndi kupereka colloid yoteteza.

Zosungunuka mosavuta m'madzi pa 20°C. Zosasungunuka mu zosungunulira za organic.Lili ndi ntchito za thickening, kuyimitsa, kumanga, emulsifying, kubalalitsa, ndi kusunga chinyezi.Mayankho osiyanasiyana mamasukidwe akayendedwe osiyanasiyana akhoza kukonzekera.Ili ndi kusungunuka kwabwino kwa mchere kwa ma electrolyte.

Kukhuthala kumasintha pang'ono mumtundu wa PH mtengo 2-12, koma kukhuthala kumachepera kuposa izi.Lili ndi katundu wa thickening, kuyimitsa, kumanga, emulsifying, dispersing, kusunga chinyezi ndi kuteteza colloid.Mayankho osiyanasiyana mamasukidwe akayendedwe osiyanasiyana akhoza kukonzekera.
