Sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose (CMC-Na) ndi chochokera ku carboxymethylated mu cellulose ndipo ndiye 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.

2. Thupi ndi mankhwala katundu

CMC-Na mwachidule, woyera kuti wotumbululuka chikasu ufa, granular kapena fibrous zinthu, wamphamvu hygroscopicity, mosavuta sungunuka m'madzi, ndi yankho ndi mkulu mamasukidwe akayendedwe madzi pamene salowerera ndale kapena zamchere. Kukhazikika kwa mankhwala, kuwala ndi kutentha. Komabe, kutentha kumakhala kochepa kwa 80 ° C, ndipo ngati kutentha kwa nthawi yaitali pamwamba pa 80 ° C, kukhuthala kumachepa ndipo sikudzasungunuka m'madzi. Kachulukidwe wake wachibale ndi 1.60, ndipo kachulukidwe wachibale wa flakes ndi 1.59. Refractive index ndi 1.515. Imasanduka bulauni ikatenthedwa kufika 190-205°C, ndipo imatulutsa carbonize ikatenthedwa kufika 235-248°C. Kusungunuka kwake m'madzi kumadalira kuchuluka kwa m'malo. Wosasungunuka mu asidi ndi mowa, palibe mvula pakachitika mchere. Sizophweka kupesa, zimakhala ndi mphamvu zopangira emulsifying ku mafuta ndi sera, ndipo zimatha kusungidwa kwa nthawi yaitali.

3. Ntchito yaikulu

Amagwiritsidwa ntchito kwambiri m'mafakitale opangira mafuta opangira matope, zotsukira zopangira, zopangira organic detergent, nsalu zosindikizira ndi utoto, tackifier yosungunuka m'madzi pazamankhwala atsiku ndi tsiku, tackifier ndi emulsifier yamakampani opanga mankhwala, thickener kwamakampani azakudya Thickener, zomatira za ceramic. mafakitale, mafakitale phala, sizing wothandizira kwa makampani pepala, etc. Iwo ntchito ngati flocculant mu mankhwala madzi, makamaka ntchito madzi zinyalala sludge mankhwala, amene angathe kuonjezera zili olimba fyuluta keke.

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 kusintha kukoma; chifukwa ali ndi zotsatira za gel osakaniza, zimathandiza kuti gel osakaniza apangidwe bwino mu chakudya, kotero angagwiritsidwe ntchito kupanga odzola ndi kupanikizana; itha kugwiritsidwanso ntchito ngati filimu yophikira yodyera Zinthuzo zimaphatikizidwa ndi zokometsera zina ndikuyika pamwamba pazakudya zina, zomwe zimatha kusunga chakudyacho mokulirapo, komanso chifukwa ndi zinthu zodyedwa, sizimayambitsa zovuta. zotsatira pa thanzi la munthu. Chifukwa chake, CMC-Na ya kalasi yazakudya, monga chowonjezera chabwino chazakudya, imagwiritsidwa ntchito kwambiri pakupanga zakudya m'makampani azakudya.
