Kodi nambala ya CAS 9004 62 0 ndi chiyani?

Nambala ya CAS 9004-62-0 ndi nambala yozindikiritsa mankhwala a Hydroxyethyl Cellulose (HEC). Ma cellulose a Hydroxyethyl ndi polima osasungunuka m'madzi omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana ndi tsiku ndi tsiku okhala ndi zinthu zokhuthala, zokhazikika, zopanga mafilimu komanso ma hydration. Lili ndi ntchito zosiyanasiyana, zophimba, zomangamanga, chakudya, mankhwala, zodzoladzola ndi zina.

1. Basic katundu wa Hydroxyethyl Cellulose

Molecular formula: Kutengera kuchuluka kwake kwa polymerization, ndi chochokera ku cellulose;

Nambala ya CAS: 9004-62-0;

Maonekedwe: Ma cellulose a Hydroxyethyl nthawi zambiri amawoneka ngati ufa woyera kapena wopepuka wachikasu, wopanda fungo komanso wopanda kukoma;

Kusungunuka: HEC ikhoza kusungunuka m'madzi ozizira ndi otentha, imakhala ndi kusungunuka kwabwino komanso kukhazikika, ndipo imapanga njira yowonekera kapena yowonekera pambuyo pa kusungunuka.

Kukonzekera kwa Hydroxyethyl Cellulose
Ma cellulose a Hydroxyethyl amapangidwa ndi cellulose yomwe imakhudzidwa ndi ethylene oxide. Pochita izi, ethylene oxide imakhudzidwa ndi gulu la hydroxyl la cellulose kudzera mu etherification reaction kuti ipeze hydroxyethylated cellulose. Ndi kusintha mmene zinthu, mlingo wa hydroxyethyl m'malo akhoza lizilamuliridwa, potero kusintha madzi solubility, mamasukidwe akayendedwe ndi zina thupi katundu HEC.

2. Thupi ndi mankhwala katundu wa hydroxyethyl mapadi

Kayendetsedwe kamakayendedwe: Hydroxyethyl mapadi ndi thickener ogwira ndipo chimagwiritsidwa ntchito kusintha mamasukidwe akayendedwe a zakumwa. Yake njira mamasukidwe akayendedwe zimadalira solubility ndende, digiri ya polymerization ndi digiri ya m'malo, kotero ake rheological katundu akhoza lizilamuliridwa ndi kusintha maselo kulemera;
Ntchito yapamtunda: Popeza kuti mamolekyu a HEC ali ndi magulu ambiri a hydroxyl, amatha kupanga filimu ya molekyulu pa mawonekedwe, amasewera gawo la surfactant, ndikuthandizira kukhazikika kwa emulsions ndi kuyimitsidwa;
Katundu wopanga mafilimu: Hydroxyethyl cellulose imatha kupanga filimu yofananira pambuyo poyanika, motero imagwiritsidwa ntchito kwambiri muzodzoladzola, zokutira zamankhwala ndi madera ena;
Kusunga chinyezi: Ma cellulose a Hydroxyethyl ali ndi hydration yabwino, amatha kuyamwa ndikusunga chinyezi, ndipo amathandizira kuwonjezera nthawi yonyowa ya mankhwalawa.

3. Malo ogwiritsira ntchito

Zovala ndi zomangira: HEC ndi chowonjezera chomwe chimagwiritsidwa ntchito kwambiri komanso chokhazikika pamakampani opanga zokutira. Ikhoza kusintha maonekedwe a zokutira, kupangitsa kuti zokutira zikhale zofanana, komanso kupewa kugwa. Pazomangira, amagwiritsidwa ntchito mumatope a simenti, gypsum, putty powder, ndi zina zotero, kuti apititse patsogolo ntchito yomanga, kupititsa patsogolo kusungirako madzi ndikuwongolera kukana kwa ming'alu.

Mankhwala atsiku ndi tsiku: Muzodzoladzola ndi zinthu zosamalira anthu, HEC imagwiritsidwa ntchito nthawi zambiri mu shampo, gel osamba, mafuta odzola ndi zinthu zina kuti apereke kukhazikika komanso kuyimitsidwa, kwinaku akuwonjezera kunyowa.

Makampani azakudya: Ngakhale HEC sagwiritsidwa ntchito kawirikawiri m'zakudya, imatha kugwiritsidwa ntchito ngati chowonjezera komanso chokhazikika muzakudya zina monga ayisikilimu ndi zokometsera.

Munda wa zamankhwala: HEC imagwiritsidwa ntchito makamaka ngati thickener ndi matrix kwa makapisozi mu kukonzekera mankhwala, makamaka mankhwala ophthalmic kupanga misozi yokumba.

Makampani opanga mapepala: HEC imagwiritsidwa ntchito ngati chowonjezera mapepala, chosalala pamwamba komanso chowonjezera chopaka mumakampani opanga mapepala.

4. Ubwino wa hydroxyethyl cellulose

Kusungunuka kwabwino: HEC imasungunuka mosavuta m'madzi ndipo imatha kupanga yankho la viscous mwachangu.

Kusinthasintha kwapang'onopang'ono: HEC ndiyoyenera kutengera mitundu yosiyanasiyana ya media ndi pH.
Kukhazikika kwamankhwala abwino: HEC imakhala yokhazikika mumitundu yosiyanasiyana ya zosungunulira ndi kutentha ndipo imatha kusunga ntchito zake kwa nthawi yayitali.

5. Thanzi ndi chitetezo cha hydroxyethyl cellulose

Hydroxyethyl cellulose nthawi zambiri imatengedwa kuti ndi chinthu chomwe chilibe vuto m'thupi la munthu. Sili poizoni ndipo sichikwiyitsa khungu kapena maso, choncho imagwiritsidwa ntchito kwambiri muzodzoladzola ndi mankhwala. M'chilengedwe, HEC ilinso ndi biodegradability yabwino ndipo sichimayambitsa kuipitsa chilengedwe.

Ma cellulose a Hydroxyethyl omwe amaimiridwa ndi CAS No. Chifukwa cha kukhuthala kwake, kukhazikika, kupanga mafilimu, kunyowa ndi zinthu zina, zimagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zopanga mafakitale ndi moyo wa tsiku ndi tsiku.
