Udindo wa hydroxye ethyl cellulose (hec) mu chemistry

Hydroxye ethyl cellulose (hec) ndi gawo logwiritsidwa ntchito kwambiri komanso gawo lofunikira kwambiri m'mapulogalamu osiyanasiyana mu magwiridwe antchito. Madzi -Sioble Polymer ali mu cellulose, ndi cellulose ndi polymer yachilengedwe yomwe imapezeka pobzala cell khoma. Kukhazikitsidwa kwa gulu la hydroxyl kumatha kukulitsa kusungunuka kwamadzi ndikusintha zinthu zakuthupi ndi mankhwala a cellulose.

1. Kuyambitsa kwa hydroxye ethyl (hec)

Hydroxye ether ndi chotupa cha cellulose, ndi celloulose ndi polymer yopangidwa ndi gawo la glucose lolumikizidwa ndi β-1,4-glycoside. Gulu la hydroxyl ku Hec linayambitsidwa ndi momwe oxide adachitira. Kusintha kumeneku kumawonjezera kusungunuka kwa polima m'madzi, ndikuwapatsa mawonekedwe apadera a kupeza magwiridwe antchito pamankhwala osiyanasiyana.

2. Kapangidwe ndi mawonekedwe a HeC

Kapangidwe: Gulu la hydroxyyl limaphatikizidwa ndi gulu la hydroxyl la ukwati waukulu wa cellulose, yomwe imapatsa a Hec mwachisawawa komanso osakhazikika. Mlingo wambiri (DS) umayimira kuchuluka kwa magulu a hydroxyl a gulu lililonse la glucose ndikukhudza mawonekedwe a polymer.

Kusungunuka: Hec imatha kusungunuka mosavuta m'madzi ozizira, ndikupanga yankho lowunikira komanso mawonekedwe a viscous. Mphamvu ya kusungunuka imakhudzidwa ndi zinthu monga kutentha, ph ndi hion mphamvu.

Ma Isccess: Chimodzi mwazinthu zofunikira za Hec ndi kuthekera kwake kuyisintha mafayilo a yankho. Izi zimapangitsa kukhala yofunika m'makampani omwe amayendetsa madzi.

3. Synthesis ya hydroxyl ethy cellulose

Zotsatira zake: kaphatikizo wa Hec kumaphatikizapo zomwe pakati pa cellulose ndi ma oxide osakhalapo alkalines. Mutha kuwongolera digiri yosinthidwa ndikusintha zomwe zimachitika (monga kutentha, nthawi, komanso mwazimiriza).

Kuyeretsa: Zinthu zomaliza zimayeretsedwa nthawi zambiri zimayeretsedwa kuti zichotse zodetsa komanso zosawoneka bwino kuti zitsimikizire mawonekedwe a HeC.

4. Kugwiritsa ntchito mankhwala

Utoto ndi zokutira: Hec amagwiritsidwa ntchito ngati kukula ndi okhazikika m'madzi ovala madzi ndi zokutira. Imakhala ndi mikhalidwe yogwiritsira ntchito ndikuwonjezera utoto wa utoto.

Zodzikongoletsera komanso zinthu zosamalira payekha: chifukwa cha yankho lake lamadzi ndi mawonekedwe ake, hec imatha kupezeka muzodzikongoletsera komanso maphikidwe amunthu, kuphatikizapo zodzola.

Mankhwala opanga mankhwala: M'mitundu ya pharmaceumical, hec imagwiritsidwa ntchito ngati mapiritsi, filimu ndi ma vina osintha, ma gels am'deralo komanso makina oyendetsa mankhwala omasulira.

Makampani opanga: Hec amagwiritsidwa ntchito popanga zinthu zomanga, monga simenti-anasuta matope ndi zomatira kuti azitha kusintha zida ndi kutsatira.

5. Udindo wamadzi otsatsa

Pubnin formula: kuphatikiza hec m'madzi omata zomatira kuti apereke mawonekedwe omata a kuwongolera mafakini, kukhazikika komanso kusintha. Ndikofunika kwambiri pakugwiritsa ntchito kosayenera kwa zotupa-zomata.

6. Kubwezeretsa Mafuta

UPCCNAME WOMVIFIFIFIER: Mu mafakitale ndi mafakitale a mafuta, hec imagwiritsidwa ntchito ngati ma visa osintha kuti apititsetse kusintha kwamafuta (eror). Zimakhala bwino mafashoni amadzi omwe amagwiritsidwa ntchito jakisoni, potero amalimbikitsa kuchotsedwa kwa mafuta mu malo osungira.

7. Mphamvu ya chilengedwe ndi chilengedwe

Kuwonongeka kwa bio: Hec nthawi zambiri amadziwika kuti ndi biodeggrad ndipo amathandizira kuti azigwirizana ndi chilengedwe. Komabe, kudalirika konse kwa kupanga kwake kumadalira zinthu monga celloling ndi kupanga.

8.. Zovuta ndi malingaliro amtsogolo

Mabizinesi: ngakhale Hec nthawi zambiri amadziwika kuti ndi otetezeka, chifukwa chake kudziletsa komanso kuthekera kwaumoyo pamapulogalamu ena, makamaka pankhani yazachipatala ndi mankhwala osokoneza bongo, pofufuza.
Green ikuluitali: Kuyesayesa kosalekeza kumayang'ana pa kukula kwa njira zophatikizira zachilengedwe zochepetsera chilengedwe cha kupanga chilengedwe.
Hydroxyeyl cellulose imagwira ntchito yofunika kwambiri pakugwiritsa ntchito mankhwala osiyanasiyana, kupereka mitundu yapadera yamadzi - kusuta, kudzipatula kwa ma visa ndi biodegration. Mphamvu zake zimathandizira mafakitale monga utoto, zodzoladzola, mankhwala, zomata komanso kuchira kwamafuta. Pomaliza kafukufuku, mtundu wa Hec ndi zomwe zingathe kugwiritsa ntchito m'minda yomwe ikubwera imatha kukula, potero kupitiliza kufunikira kwa munda wa mamakhalidwe.

Hydroxye ethyl cellulose imatsimikizira zosowa za polymer pompopompo mu mitundu yosiyanasiyana ya mankhwala, ndipo zimathandizira kukulitsa madera ambiri omwe amadalira zida zowonjezera.
