Hydroxyethyl cellulose (hec) ndiopanda poizoni, kusungunuka police-madzi wochokera ku cellulose pogwiritsa ntchito mankhwala. Zimagwiritsidwa ntchito kawirikawiri m'mafakitale osiyanasiyana monga zodzoladzola, mankhwala opangira mankhwala, zomangamanga, ndi kupanga zakudya chifukwa chokhazikika, komanso madzi okhazikika. Komabe, ngati mankhwala aliwonse mankhwala, chitetezo chake chimadalira pakugwiritsa ntchito ndi kuzunzika.
Kuyamba kwa Hydroxyethyl cellulose (hec)
Hec ndi a banja la cellulose, lomwe limazungulira ma cellulose osiyanasiyana omwe amapangidwa pogwiritsa ntchito mankhwala. Kuphatikiza kwa magulu a hydroxyethyl ku mamolelules a cellulose kumawonjezera kusungunuka kwawo m'madzi, kupanga phula lofunika kwambiri m'matumba pomwe mikangano yamadzi ikufalikira.
1. 1.Parmies a Hec:
Kusungunuka kwamadzi: Hec akuwonetsa kusungunuka kwambiri m'madzi, ndikupanga mayankho omveka bwino komanso a viscous.
Kusintha kwa magazi: kumatha kusintha mafayilo osintha, ndikupangitsa kukhala wothandiza kwambiri.
Kukhazikika: Hec imathandizira kukhazikika kwa mapangidwe, kupewa gawo lolekanitsa ndikusintha moyo.
Mapangidwe a filimu: ili ndi katundu wopanga mavidiyo, ndikupangitsa kuti ikhale yothandiza ndikumatira ndi zomatira.
Kugwiritsa Ntchito:
Zodzikongoletsera komanso chisamaliro chaumwini: Hec imagwiritsidwa ntchito kwambiri mu shampoos, zodzola, mafuta, ndi ma gels ngati kukula ndi kukhazikika.
Mankhwala ogulitsa: Imapeza mapulogalamu oyikidwa pakamwa, mapangidwe apamwamba, ndi ma ophthalmic chifukwa chokhoza kusintha mavidiyo ndikusintha kapangidwe kake.
Ntchito Yomanga: Hec imagwiritsidwa ntchito muzogulitsa za simenti kuti zitheke, kusungidwa kwamadzi, komanso kutsatira.
Makampani ogulitsa zakudya: Makampani ogulitsa zakudya, imakhala ngati thiccener, kukhazikika, ndi emulsister, ndi zotupa, zotanulira, ndi zakudya.
Maganizo a chitetezo
Mbiri Yakale -
Kuopsa kotsika: Hec nthawi zambiri amawoneka otetezeka kuti agwiritse ntchito pogwiritsa ntchito osiyanasiyana.
Osakwiya: Sizimakwiyira khungu ndi maso nthawi zambiri.
Kupanda chidwi: Hec sikuyambitsa mavuto.
4.
Kuopsa Kwakupsa: Tinthu tating'onoting'ono ta hec kungawonongere ngozi ngati infrive.
Kukhazikika kwakukulu: kugwiritsa ntchito kwambiri kapena kulowetsa kwa ma socmit a hec kumatha kukhala ndi vuto la m'mimba.
Zoipa: Zosakonzekera mu khasu kukonzekera zitha kukhala zoopsa kutengera chikhalidwe chawo komanso chidwi chawo.
5.Fda Malangizo:
Ku United States, chakudya ndi mankhwala osokoneza bongo (FDA) amayang'anira chizolowezi mu chakudya, mankhwala opangira mankhwala, komanso zodzoladzola. Zimavomereza magiredi enieni a Hec pazomwe amagwiritsa ntchito potengera chitetezo cha chitetezo.
6.Eurucan Union:
Ku European Union, Hec amakhazikitsidwa pansi (kulembetsa, kuwunika, chilolezo, ndi zoletsa za mankhwala).
Hydroxyethyl cellulose (hec) ndi polima molimbirana polima mafakitale osiyanasiyana. Akagwiritsidwa ntchito molingana ndi malangizo a retutury ndi makampani, amapereka chiopsezo chochepa thanzi la anthu komanso chilengedwe. Komabe, ngati mankhwala aliwonse mankhwala, kuyendetsa bwino, kusungidwa koyenera, kusungirako, ndi machitidwe otayika ndikofunikira kuti muchepetse ngozi. Ponseponse, Hec akupitilizabe kusewera mbali yofunika kwambiri yolimbikitsira mtundu ndi magwiridwe antchito ambiri pomwe mukukhala ndi mbiri yabwino.
