Hydroxyethyl methl cellulose (hemc)ndi ma cellulose ofunika kwambiri ndipo ndi a ether ether ether. Hemc imapezeka ndi kusintha kwa mankhwala ndi cellulose yachilengedwe ngati zipatso. Kapangidwe kake kamakhala ndi hydroxyethyl ndi methyl oyang'anira, motero amakhala ndi zinthu zapadera komanso mankhwala ndipo amagwiritsidwa ntchito pomanga, mankhwala, mankhwala ndi minda ina.
1. Mankhwala akuthupi ndi mankhwala
Hemc nthawi zambiri imakhala yoyera kapena yoyera-yoyera, yomwe imasungunuka mosavuta m'madzi ozizira kuti apange yankho lowunikira kapena pang'ono la Conloidal. Makhalidwe ake akulu amaphatikizapo:
Kusungunuka: Hemoc imatha kusungunuka mwachangu m'madzi ozizira, koma ali ndi malo osauka m'madzi otentha. Kusungunuka kwake ndikusintha kwa kusintha kwa kutentha ndi mtengo wa pH.
Kukula Kwakukulu: hemc imakhala ndi luso lamphamvu m'madzi ndipo limatha kuwonjezera mawidwe a yankho.
Kusungidwa kwamadzi: Pali kusunga bwino kwamadzi ndipo kumatha kupewa kutaya madzi.
Katundu wopanga makanema: hemc imatha kupanga filimu yowoneka bwino padziko lapansi ndi kulimba mtima kwakanthawi komanso nyonga.
Thuma: Chifukwa chazosanja zake zapadera, hemoc amatha kupatsa mafuta abwino kwambiri.
2. Kupanga Njira
Njira zopangira za hemc makamaka zimaphatikizapo njira zotsatirazi:
Alkalilization: Cellulose yachilengedwe imathandizidwa ndi alkalines kuti apange alkali cellulose.
Kutengera kwa chizolowezi: powonjezera othandizira
Chithandizo: Chithandizo cha satana chimasankhidweratu, kutsukidwa, chouma, ndikuphwanyaHemoZogulitsa.
3. Madera Ogwiritsira ntchito
. Zimatha kusintha mafayilo, kusunga madzi komanso madambo oletsa zomangamanga, kumathandizira nthawi yotseguka, ndikuwonjezera ntchito yomanga.
. Kuphatikiza apo, imatha kupereka katundu wabwino wopanga mafilimu, ndikupanga utoto yunifolomu yambiri komanso yosalala.
. Chifukwa cha chitetezo chake chachikulu komanso kupanda chitetezo, nthawi zambiri zimagwiritsidwa ntchito pazogulitsa monga mawonekedwe monga mawonekedwe, nkhope ya nkhope, ndi mafuta odzola.
.
4. Ubwino ndi Chitetezo Chachilengedwe
Hemc ali ndi biodegration komanso zachilengedwe kuteteza ndipo sichingapangitse kuwonongeka kwa nthawi yayitali ku chilengedwe. Nthawi yomweyo, sikuti ndi zoopsa komanso zopanda vuto, osakwiyitsa khungu la anthu ndi ma nembaous membranes, ndipo amakwaniritsa zofunikira za chilengedwe chobiriwira komanso chitukuko chokhazikika.
5. Chiyembekezo cha msika ndi zochitika za chitukuko
Ndi chitukuko cha makampani omanga komanso makampani tsiku lililonse mankhwala, zomwe zimafunikira pamsika wa hemac zikukula. M'tsogolomu, anthu akamayang'anira kwambiri zida zosangalatsa komanso kukonza magwiridwe antchito, hemoc adzagwiritsidwa ntchito kwambiri m'minda yosiyanasiyana. Kuphatikiza apo, kafukufukuyu ndi chitukuko cha zinthu zatsopano zoyendetsera hemc (monga kutentha kwambiri ndikuyimitsa) kudzalimbikitsanso ntchito yake pamsika wotsiriza.
Monga ma etherlose a celluser am'mwamba,hydroxyethyl methylcelulose (hemc)Amagwira ntchito yofunika kwambiri pomanga, zokutira, mankhwala ndi minda ina yokhala ndi mawonekedwe ake apadera ndi mankhwala. Popita patsogolo kwa sayansi ndi ukadaulo ndi kufulumira kwa minda yofunsira, hemc idzathandiza kwambiri mu makampani amakono ndikuthandizira kwambiri kukulitsa mafakitale ofananira.
