Hydroxyethyl cellulose ndi ethyl cellulose

1. Malingaliro oyambira

Hydroxyethyl cellulose (hec): hydroxethyl cellulose (hec) ndi polymer yachilengedwe ya polymer, nthawi zambiri imatengedwa ndikuwunika kwa cellulose. Gulu la hydroxyethyl (-ch2chtoh) limayambitsidwa mu molekyulu yake, ndikupereka madzi abwino kuthira, kukula, kuphatikizira ndi ntchito. Hec imagwiritsidwa ntchito kwambiri m'minda monga zofunda, zodzoladzola, zonunkhira, tsabola, chakudya, mankhwala othandizira.

Ethyl cellulose (ECYL Cellulose (EC) ndi gawo la ether lomwe limachokera ku cellulose wachilengedwe. Mosiyana ndi Hec, wa ethyl (-c2h5) umayambitsidwa mu molekyulu ya EC m'malo mwa gulu la hydroxyathyl. Ili ndi kusauka kosavuta ndipo nthawi zambiri imasungunuka mu ortic sodics koma osakhazikika m'madzi. EC imagwiritsidwa ntchito makamaka m'mafakitale monga mankhwala opangira mankhwala, zofunda ndi zomatira, ndipo zakhala zikukula, kukhazikika komanso kukhazikika ndi makanema.

2. Kusiyana kwa kapangidwe ka mankhwala ndi kusungunuka

Kapangidwe ka mankhwala:
Makina a hexcular a hec amapangidwa ndikusintha ma molekyulu a cellulose kudzera pa hydroxyethyl (chanchtohh) magulu. Kusintha kumeneku kumapangitsa kuti akhale wa hydrophilic ndipo amatha kusungunuka m'madzi.
Mu ma molekyulu a EC, magulu a ethyl (C2h5) m'malo mwa magulu ena a hydroxyl mu cellulose, zomwe zimapangitsa ma molekyubic ake komanso kusungunuka bwino m'madzi, nthawi zambiri amasungunuka mu ordontain.
Kusungunuka:

Hec imasungunuka mosavuta m'madzi, makamaka m'madzi ofunda, ndipo kusungunuka kwake kumakhudzana ndi kunenepa komanso kuchuluka kwa hydroxuthy. Chifukwa cha kusandulika kwamadzi, hec nthawi zambiri amagwiritsidwa ntchito m'malo omwe kususuka kuthira kumafunikira, monga zokutira, otuwa, etc.
EC EC yokhala ndi malo osauka m'madzi, koma ali ndi kusungunuka bwino mu ordic sols omwe amasungunulira monga mowa woledzera ndi ketone sol. Chifukwa chake, EC nthawi zambiri imagwiritsidwa ntchito mu madera owoneka ngati organic kapena filimu yomwe kale.

3. Zolemba

Kugwiritsa ntchito Hec:
Zovala: Hec imagwiritsidwa ntchito ngati thickier ndi rheology yodzitchitsira zokutira zozikidwa pamadzi, zomwe zimatha kusintha madzi, kuyimitsidwa ndi anti-anti-tortives a zokutira.
Zodzikongoletsera: M'mfakitara yamadziko lodzikongoletsera, nthawi zambiri imagwiritsidwa ntchito ndi zinthu monga zotupa, shampoos, ndi khungu lotupa, emulsifier, komanso wopusa.
Chithandizo: Hec amagwiritsidwanso ntchito pokonzekera mankhwala oyenera kumasulidwa ngati thickener ndi gelling wothandizila kuti athandize kumasulidwa kwa mankhwala.
Ntchito Yomanga: Mu makampani omanga, Hec imagwiritsidwa ntchito ngati chungula kwa simenti kapena matope kuti mupitirize kusintha magwiridwe antchito, monga kupitirira nthawi yolimbitsa thupi komanso kusintha mabizinesi.

Kugwiritsa ntchito EC:
Mankhwala ogulitsa: Ethyl cellose nthawi zambiri imagwiritsidwa ntchito mu gawo la mankhwala, makamaka pokonzekera mankhwala osokoneza bongo, monga chonyamula mankhwala, zokutira kanema, zowonjezera, etc.
Zophatikiza ndi zomatira: Makampani ophatikizira, EC imagwiritsidwa ntchito ngati thiccener ndi filimu yomwe kale. Itha kuwonjezera makulidwe a zokutira ndi zowonjezera nyengo.
Chakudya: EC imagwiritsidwanso ntchito pamunda wa chakudya, makamaka ngati tricker ndi kukhazikika, ndipo amagwiritsidwa ntchito mu zakudya monga mafuta ndi maswiti.
Zodzikongoletsera: EC imagwiritsidwa ntchito modzola kuti muwonjezere mawonekedwe komanso kukhazikika kwa emulsions, ndipo imatha kugwiritsidwanso ntchito ngati chisamaliro cha khungu.

4. Kuyerekeza magwiridwe antchito

Kukula:
Onse a Hec ndi EC ali ndi zotsatira zabwino kwambiri, koma hec amawonetsa mwamphamvu m'madzi, oyenera kwambiri kusinthidwe. EC imawonetsa kusintha kwabwino kwambiri m'malo okhazikika chifukwa cha hydrophobity yake.

Kususuka ndi kukhazikika:
Hec ali ndi madzi abwino osungunuka ndi okhazikika osinthika, motero amagwiritsidwa ntchito mwamphamvu m'magulu am'madzi. EC ilibe kusungunuka kwambiri ndipo imagwiritsidwa ntchito kwambiri mu orthy sols kapena ma systems.

Rheology:
Zovuta za hec yamagetsi zimasiyana kwambiri m'malo osiyanasiyana, nthawi zambiri zimawonetsa madzi osadziwika omwe si Mboni. EC nthawi zambiri imakhala ndi chizolowezi chokhazikika, makamaka mokhazikika.

Hydroxyethyl cellulose (hec) ndi ethyl cellulose (EC) ndi ma cellulose awiri omwe ali ndi ma cellulose ofala, aliyense ndi zinthu zapadera komanso mankhwala komanso kugwiritsa ntchito mitundu ingapo. Madzi a hec solubility ndi makulidwe omwe amakula zimapangitsa kugwiritsidwa ntchito kwambiri pamakina opangidwa ndi madzi, monga zokutira, zodzoladzola, ndi mankhwala. EC nthawi zambiri imagwiritsidwa ntchito mu miyambo yosungunuka, monga mankhwala opangira mankhwala, zowonjezera, zomata, ndi zina zowirikiza, chifukwa cha kusungunuka kwake koyenera komanso hydrophobicity yabwino. Kusankha kwa awiriwa kuyenera kutsimikizika molingana ndi zofunikira pa ntchito ndi mtundu wa zosungunulira zomwe zimagwiritsidwa ntchito.
