Kodi nambala ya CAS 9004 62 0 ndi chiyani?

Nambala ya CAS 9004-62-0 ndi nambala yodziwira mankhwala ya Hydroxyethyl Cellulose (HEC). Hydroxyethyl Cellulose ndi polima yosasungunuka m'madzi yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana komanso tsiku ndi tsiku yokhala ndi mphamvu zokhuthala, zokhazikika, zopanga filimu komanso zonyowa. Ili ndi ntchito zosiyanasiyana, kuphatikizapo zokutira, zomangamanga, chakudya, mankhwala, zodzoladzola ndi zina.

1. Katundu woyambira wa Hydroxyethyl Cellulose

Fomula ya mamolekyu: Kutengera ndi kuchuluka kwa polymerization yake, ndi chochokera ku cellulose;

Nambala ya CAS: 9004-62-0;

Mawonekedwe: Hydroxyethyl Cellulose nthawi zambiri imawoneka ngati ufa woyera kapena wachikasu wopepuka, wopanda fungo komanso wopanda kukoma;

Kusungunuka: HEC imatha kusungunuka m'madzi ozizira komanso otentha, imakhala ndi kusungunuka bwino komanso kukhazikika, ndipo imapanga yankho lowonekera kapena lowala pambuyo posungunuka.

Kukonzekera kwa Hydroxyethyl Cellulose
Hydroxyethyl Cellulose imakonzedwa pogwiritsa ntchito cellulose yomwe imagwira ntchito ndi mankhwala ndi ethylene oxide. Munjira imeneyi, ethylene oxide imagwirira ntchito ndi gulu la hydroxyl la cellulose kudzera mu etherification reaction kuti ipeze hydroxyethylated cellulose. Mwa kusintha momwe zinthu zilili, kuchuluka kwa hydroxyethyl substitution kumatha kulamulidwa, potero kusintha kusungunuka kwa madzi, kukhuthala ndi zinthu zina zakuthupi za HEC.

2. Kapangidwe ka thupi ndi mankhwala a hydroxyethyl cellulose

Kulamulira kukhuthala: Hydroxyethyl cellulose ndi chinthu chokhuthala bwino ndipo chimagwiritsidwa ntchito kwambiri kusintha kukhuthala kwa madzi. Kukhuthala kwa yankho lake kumadalira kuchuluka kwa kusungunuka, kuchuluka kwa polymerization ndi kuchuluka kwa kusintha, kotero mphamvu zake za rheological zitha kulamulidwa mwa kusintha kulemera kwa mamolekyulu;
Ntchito Yogwira Ntchito Pamwamba: Popeza mamolekyu a HEC ali ndi magulu ambiri a hydroxyl, amatha kupanga filimu ya molekyulu pa mawonekedwe ake, kusewera ngati surfactant, ndikuthandizira kukhazikika kwa emulsions ndi machitidwe oimika;
Kapangidwe ka filimu: Hydroxyethyl cellulose imatha kupanga filimu yofanana ikauma, kotero imagwiritsidwa ntchito kwambiri mu zodzoladzola, zophimba mankhwala ndi zina;
Kusunga chinyezi: Hydroxyethyl cellulose imakhala ndi madzi okwanira, imatha kuyamwa ndi kusunga chinyezi, ndipo imathandizira kuwonjezera nthawi yonyowetsa chinyezi cha chinthucho.

3. Madera ogwiritsira ntchito

Zophimba ndi zipangizo zomangira: HEC ndi chokhuthala komanso chokhazikika chomwe chimagwiritsidwa ntchito kwambiri mumakampani opanga zophimba. Chikhoza kusintha mawonekedwe a zophimbazo, kupangitsa kuti zophimbazo zikhale zofanana, komanso kupewa kugwedezeka. Mu zipangizo zomangira, chimagwiritsidwa ntchito mu simenti, gypsum, putty powder, ndi zina zotero, kuti chiwongolere magwiridwe antchito omanga, kuwonjezera kusunga madzi ndikuwonjezera kukana ming'alu.

Mankhwala a tsiku ndi tsiku: Mu zodzoladzola ndi zinthu zosamalira thupi, HEC nthawi zambiri imagwiritsidwa ntchito mu shampu, shawa gel, lotion ndi zinthu zina kuti ipangitse kukhuthala ndi kukhazikika kwa suspension, pomwe ikuwonjezera mphamvu yonyowetsa.

Makampani Ogulitsa Chakudya: Ngakhale kuti HEC siigwiritsidwa ntchito kawirikawiri mu chakudya, ingagwiritsidwe ntchito ngati chokhuthala komanso chokhazikika muzakudya zinazake monga ayisikilimu ndi zokometsera.

Munda wa zamankhwala: HEC imagwiritsidwa ntchito makamaka ngati chokhuthala komanso chopangira makapisozi m'mafakitale opangira mankhwala, makamaka m'mankhwala a maso opangira misozi yopangira.

Makampani opanga mapepala: HEC imagwiritsidwa ntchito ngati chowonjezera mapepala, chosungunula pamwamba komanso chophikira m'makampani opanga mapepala.

4. Ubwino wa hydroxyethyl cellulose

Kusungunuka bwino: HEC imasungunuka mosavuta m'madzi ndipo imatha kupanga yankho lokhuthala mwachangu.

Kugwiritsa ntchito mosiyanasiyana: HEC ndi yoyenera malo osiyanasiyana okhala ndi zinthu zosiyanasiyana komanso pH.
Kukhazikika kwabwino kwa mankhwala: HEC ndi yokhazikika bwino mu zosungunulira zosiyanasiyana ndi kutentha ndipo imatha kugwira ntchito zake kwa nthawi yayitali.

5. Umoyo ndi chitetezo cha hydroxyethyl cellulose

Hydroxyethyl cellulose nthawi zambiri imaonedwa kuti ndi chinthu chomwe sichivulaza thupi la munthu. Sichimayambitsa poizoni ndipo sichikwiyitsa khungu kapena maso, choncho chimagwiritsidwa ntchito kwambiri mu zodzoladzola ndi mankhwala. Mu chilengedwe, HEC imakhalanso ndi mphamvu yowononga chilengedwe ndipo siimayambitsa kuipitsa chilengedwe.

Hydroxyethyl cellulose yomwe imayimiridwa ndi CAS No. 9004-62-0 ndi chinthu cha polima chogwira ntchito zambiri chomwe chimagwira ntchito bwino kwambiri. Chifukwa cha kukhuthala kwake, kukhazikika, kupanga filimu, kunyowetsa ndi zina, imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana opanga mafakitale komanso moyo watsiku ndi tsiku.
