1. Kodi hydroxyethyl cellulose (HEC) ndi chiyani?
Hydroxyethyl cellulose (HEC)ndi chilengedwe cha polima pawiri ndi cellulose yochokera. Ndi ether yosungunuka m'madzi yomwe imapezeka ndi momwe cellulose imayendera ndi ethylene oxide. Kapangidwe kake ka hydroxyethyl cellulose kumakhala ndi mafupa oyambira a cellulose, ndipo nthawi yomweyo amalowetsa zolowa m'malo mwa hydroxyethyl (-CH2CH2OH) m'maselo ake, zomwe zimapangitsa kuti madzi azisungunuka komanso zinthu zina zakuthupi ndi zamankhwala. Ndi mankhwala opanda poizoni, osakwiyitsa komanso owonongeka omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
2. Kuchita kwa hydroxyethyl cellulose
Kusungunuka kwamadzi: Ma cellulose a Hydroxyethyl amakhala ndi kusungunuka kwabwino m'madzi ndipo amatha kusungunuka mwachangu m'madzi ozizira kapena otentha kuti apange yankho la viscous. Kusungunuka kumawonjezeka ndi kuwonjezeka kwa digiri ya hydroxyethylation, kotero kumakhala ndi controllability yabwino mu ntchito mafakitale.
Kukhuthala kwamakayendedwe: The kukhuthala kwa hydroxyethyl cellulose kumagwirizana kwambiri ndi kulemera kwake kwa maselo, kuchuluka kwa hydroxyethylation ndi kuchuluka kwa yankho. Kukhuthala kwake kungasinthidwe m'mapulogalamu osiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana. Pazigawo zotsika, zimakhala ngati njira yochepetsera-makamaka, pamene pazigawo zazikulu, kukhuthala kumawonjezeka mofulumira, kumapereka mphamvu za rheological.
Nonionicity: Hydroxyethyl cellulose ndi nonionic surfactant yomwe simakhudzidwa ndi kusintha kwa pH ya yankho, kotero imasonyeza kukhazikika bwino pansi pa zochitika zosiyanasiyana zachilengedwe. Katunduyu amapangitsa kuti azigwiritsidwa ntchito kwambiri pamapangidwe ambiri omwe amafunikira kukhazikika.
Kunenepa: Ma cellulose a Hydroxyethyl ali ndi mphamvu zokhuthala bwino ndipo amagwiritsidwa ntchito ngati chokhuthala m'mapangidwe ambiri otengera madzi. Iwo akhoza mogwira kuonjezera mamasukidwe akayendedwe a madzi ndi kusintha fluidity ndi operability wa mankhwala.
Kapangidwe ka filimu ndi emulsifying: Ma cellulose a Hydroxyethyl ali ndi zinthu zina zopanga filimu ndi emulsifying, ndipo amatha kumwaza zosakaniza zosiyanasiyana mu multiphase system. Katunduyu ndi wofunikira kwambiri m'makampani opanga zodzikongoletsera ndi zokutira.
Kukhazikika kwamafuta ndi kusungunuka:Hydroxyethyl celluloseimakhala yosasunthika ndi kutentha, imatha kusunga kusungunuka kwake ndikugwira ntchito mkati mwa kutentha kwina, ndikusintha kuti zigwirizane ndi zosowa za malo otentha kwambiri. Katunduyu amapangitsa kukhala kopindulitsa kugwiritsa ntchito m'malo ena apadera.
Biodegradability: Chifukwa cha gwero lake la cellulose, cellulose ya hydroxyethyl imakhala ndi kuwonongeka kwachilengedwe, kotero ilibe mphamvu pang'ono pa chilengedwe komanso ndi chilengedwe.
3. Ntchito minda ya hydroxyethyl mapadi
Makampani omanga ndi zokutira: Ma cellulose a Hydroxyethyl amagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi pantchito yomanga, ndipo amagwiritsidwa ntchito kwambiri mumatope a simenti, zomatira, matope owuma ndi zinthu zina. Ikhoza kusintha operability ndi fluidity wa zinthu, kusintha adhesion ndi madzi ntchito ❖ kuyanika. Chifukwa cha kusungirako bwino kwa madzi, imatha kukulitsa nthawi yotseguka ya zinthuzo, kuletsa kutuluka kwamadzi mwachangu, ndikuwonetsetsa kuti ntchito yomangayo ndi yabwino.
Kutulutsa mafuta ndi kubowola madzimadzi: Pochotsa mafuta, hydroxyethyl cellulose imagwiritsidwa ntchito ngati thickener pobowola madzimadzi ndi kumaliza madzimadzi, omwe amatha kusintha bwino ma rheology amadzimadzi, kupewa kuyika matope pakhoma la chitsime ndikukhazikitsa khoma lachitsime. Zitha kuchepetsanso kulowa kwa madzi ndikuwongolera bwino komanso chitetezo cha kubowola.
Makampani opanga zodzoladzola:Hydroxyethyl celluloseamagwiritsidwa ntchito kwambiri muzinthu zosamalira khungu, shampu, shawa gel, zonona kumaso ndi zinthu zina monga thickener, emulsifier ndi stabilizer mu zodzoladzola. Zitha kuonjezera mamasukidwe akayendedwe a mankhwala, kusintha fluidity wa mankhwala, kuonjezera kumverera kwa mankhwala, komanso kupanga filimu zoteteza pakhungu kuthandiza moisturize ndi kuteteza.
Makampani Opanga Mankhwala: Hydroxyethyl cellulose imagwiritsidwa ntchito ngati chomangira mankhwala, chotulutsa nthawi zonse, komanso chodzaza mapiritsi ndi makapisozi pamakampani opanga mankhwala. Ikhoza kusintha thupi la mankhwala kukonzekera ndi kumapangitsanso bata ndi bioavailability wa mankhwala.
Makampani Opangira Zovala ndi Papermaking: Pamakampani opanga nsalu, hydroxyethyl cellulose itha kugwiritsidwa ntchito ngati chothandizira chopaka utoto komanso chothandizira kusindikiza kuti utoto ufanane komanso kufewa kwa nsalu. M'makampani opanga mapepala, amagwiritsidwa ntchito ngati chokhuthala mu zokutira mapepala kuti apititse patsogolo luso losindikiza komanso gloss pamwamba pa pepala.
Makampani a Chakudya: Ma cellulose a Hydroxyethyl amagwiritsidwanso ntchito pokonza chakudya, makamaka ngati chowonjezera, emulsifier ndi stabilizer. Ikhoza kusintha kukoma ndi kapangidwe ka chakudya, mwachitsanzo, mu ayisikilimu, odzola ndi zakumwa, imatha kupititsa patsogolo kukhazikika ndi kutsekemera kwa mankhwala.
Ulimi: M'munda waulimi, hydroxyethyl cellulose imagwiritsidwa ntchito nthawi zambiri pokonzekera mankhwala ophera tizilombo, zokutira feteleza ndi zinthu zoteteza zomera. Kukhuthala kwake ndi kunyowetsa kwake kumathandizira kukulitsa kufanana ndi kumamatira kwa opopera mankhwala, potero kumapangitsa mphamvu ya mankhwala ophera tizilombo ndikuchepetsa kuwononga chilengedwe.
Mankhwala atsiku ndi tsiku: Poyeretsa m'nyumba ndi zinthu zosamalira anthu, hydroxyethyl cellulose imagwiritsidwa ntchito ngati thickener ndi stabilizer kuti apititse patsogolo kugwiritsa ntchito komanso kumva kwa chinthucho. Mwachitsanzo, nthawi zambiri amagwiritsidwa ntchito pamankhwala atsiku ndi tsiku monga zakumwa zochapira mbale, zotsukira zovala, ndi zotsukira kumaso.
Hydroxyethyl cellulosendi mamolekyu apamwamba kwambiri omwe amagwira ntchito bwino kwambiri komanso amagwiritsidwa ntchito mosiyanasiyana. Kusungunuka kwake m'madzi, kukhuthala, kukhazikika kwamafuta komanso kuwonongeka kwachilengedwe kumapangitsa kuti azigwiritsidwa ntchito kwambiri m'magawo ambiri monga zomangamanga, mafuta, zodzoladzola, mankhwala, ndi nsalu. Ndi kusintha kwa zofunikira zachitetezo cha chilengedwe komanso kupita patsogolo kwaukadaulo, chiyembekezo chogwiritsa ntchito HEC chidzakhala chokulirapo ndikukhala chisankho chofunikira pazida zobiriwira zoteteza chilengedwe ndi zowonjezera zowonjezera.
