Hydroxyethyl cellulose (hec) ndi polymer yopanda madzi, yosungunuka yochokera ku cellulose, policmer mwachilengedwe amapezeka m'makoma a cell a mbewu. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga mankhwala opangira mankhwala, zodzoladzola, zomata, komanso zinthu zina chifukwa cha zovuta zake, kukhazikika, komanso kukhazikika kwa madzi. Komabe, kukambirana za mtengo wa Hec kumafuna kumvetsetsa kwakukulu kwa malo ake, kapangidwe kake, ndi ntchito.
Kumvetsetsa ma hydroxyethyl cellulose (hec):
1. Kapangidwe ka mankhwala:
Hec imapangidwa ndi zomwe wapasintha cellulose ndi ethylene oxide, zomwe zimapangitsa kuti ma hydroxyethyl magulu a hydroxyethyl.
Mlingo wa zolowa m'malo (DS) amatanthauza kuchuluka kwa ma hydroxyethyl magulu pa ulalo wa glucose mu cellulose mu cellulose unyolo ndikuwonetsa katundu wa HeC. Malingaliro apamwamba a DS DS amatsogolera kuti achuluke madzi osungunuka ndi kukweza.
2. Katundu:
Hec amasungunuka m'madzi ndikupanga njira zomveka bwino, zomwe zimapangitsa kuti zizikhala zoyenera kugwiritsa ntchito njira zosiyanasiyana zofunira mapangidwe owonekera.
Imawonetsa machitidwe a pseudoplactic, kutanthauza kuti ma viscy ake amachepa pansi pa kupsinjika kukameta ubweya, kulola kugwiritsa ntchito mosavuta ndi kusamalira.
Makulidwe a zothetsera hec amatengera zinthu monga chidwi, kutentha, Ph, ndi kupezeka kwa mchere kapena zina zowonjezera.
3. Ntchito:
Mankhwala ogulitsa: Hec amagwiritsidwa ntchito ngati thickir ndi okhazikika mu pakamwa komanso zolimbitsa thupi monga mafuta, mafuta, ndi kuyimidwe.
Zodzikongoletsera: Ndiofala wamba pazinthu zosamalira zaumwini kuphatikiza shampoos, zodzola, ndi zonona chifukwa cha kukula kwake komanso kutulutsa zinthu.
Utoto ndi zokutira: Hec amawonjezeredwa ndi utoto, zomatira, ndi zomatira kuwongolera mafakisoni, kusintha zinthu zamagetsi, komanso kukulitsa makanema.
Makampani Ogulitsa Chakudya: Zakudya za chakudya, hec amagwira ntchito ngati thicker, chikhazikitso, ndi emulsister, mavalidwe, zovala, ndi mkaka.
mtengo wamtengo wa hydroxyethyl cellulose (hec):
1 .Z kudalira:
PH ya yankho lomwe ili ndi Hec imatha kusintha machitidwe ake ndi magwiridwe ake mu ntchito zosiyanasiyana.
Nthawi zambiri, hec imakhala yokhazikika pamafu osiyanasiyana, nthawi zambiri pakati pa pH 2 ndi ph 12. Komabe, mak zosintha kwambiri amatha kukhudza zinthu zake komanso kukhazikika kwake.
2. Zotsatira za ma visct:
Mawonekedwe a zothetsera HeC akhoza kukhala ph-wodalirika, makamaka pamtengo wapamwamba kapena wotsika pH.
Pafupi ndi a Adutral ph ph (ph 5-8), ma hec nthawi zambiri amawonetsa ma victoni awo kwambiri.
Pamkhalidwe wotsika kwambiri kapena wapamwamba kwambiri.
3. Mawu Kusintha:
M'mapanga pomwe kusintha kwa ph ndikofunikira, zotchinga nthawi zambiri zimagwiritsidwa ntchito kusunga njira zingapo zomwe mukufuna.
Zofananira zofala monga Citrate kapena zingwe za phosphate ndizogwirizana ndi Hec ndikuthandizira kukhazikitsa malo ake mkati mwa mankhunje.
4. Malingaliro a ntchito:
Opanga apangidwe ayenera kuganizira mogwirizana ndi phzo za hec ndi zosakaniza zina popanga.
Nthawi zina, kusintha kwa PH kwa mawonekedwe atha kuyesedwa kuti athetse magwiridwe antchito a HeC.
Hydroxyethyl cellulose (hec) ndi polima molimbirana polima mafakitale osiyanasiyana. Pomwe mafa ake amakhazikika nthawi zambiri amakhala olimba pamitundu yosiyanasiyana, ma P Kuzindikira kudalira kwa Hec ndikofunikira kuti mupange zinthu zogwira ntchito zothandiza m'mapanga, zodzoladzola, zotupa, zomata, zomata, ndi zina. Poganizira za kuchuluka kwa pH ndikugwiritsa ntchito njira zoyenera zopangira, HEC imatha kupitiliza kukhala yofunika kwambiri mu mapulogalamu osiyanasiyana.
