Kugawa kwa Zinthu za Methyl Cellulose

Zogulitsa za Methyl cellulose (MC) zitha kugawidwa m'magulu kutengera zinthu zosiyanasiyana monga kuchuluka kwa kukhuthala kwawo, digiri ya kusintha (DS), kulemera kwa mamolekyulu, ndi kugwiritsa ntchito. Nazi mitundu yodziwika bwino ya zinthu za methyl cellulose:

1. Kalasi Yokhuthala:
   • Zinthu zopangidwa ndi methyl cellulose nthawi zambiri zimagawidwa m'magulu kutengera kuchuluka kwa kukhuthala kwawo, komwe kumagwirizana ndi kukhuthala kwawo m'madzi. Kukhuthala kwa njira za methyl cellulose nthawi zambiri kumayesedwa mu centipoise (cP) pamlingo winawake ndi kutentha. Mitundu yodziwika bwino ya kukhuthala ndi monga kukhuthala kochepa (LV), kukhuthala kwapakati (MV), kukhuthala kwakukulu (HV), ndi kukhuthala kwakukulu kwambiri (UHV).
2. Degree of Substitution (DS):
   • Zogulitsa za Methyl cellulose zitha kugawidwanso m'magulu kutengera kuchuluka kwa zomwe zimasinthidwa, zomwe zikutanthauza kuchuluka kwa magulu a hydroxyl pa unit iliyonse ya shuga yomwe yasinthidwa ndi magulu a methyl. Ma DS apamwamba amasonyeza kuchuluka kwa kusintha ndipo nthawi zambiri zimapangitsa kuti kusungunuka kukhale kwakukulu komanso kutentha kochepa kwa gelation.
3. Kulemera kwa Maselo:
   • Zinthu zopangidwa ndi methyl cellulose zimatha kukhala ndi kulemera kwa mamolekyulu osiyanasiyana, zomwe zingakhudze momwe zimakhalira monga kusungunuka, kukhuthala, ndi kachitidwe ka gelation. Zinthu zopangidwa ndi methyl cellulose zokhala ndi kulemera kwa mamolekyulu ambiri nthawi zambiri zimakhala ndi kukhuthala kwakukulu komanso mphamvu ya gelling poyerekeza ndi zinthu zopangidwa ndi kulemera kwa mamolekyulu ochepa.
4. Magiredi Omwe Amagwiritsidwa Ntchito:
   • Zinthu zopangidwa ndi methyl cellulose zitha kugawidwa m'magulu kutengera momwe zimagwiritsidwira ntchito. Mwachitsanzo, pali mitundu yeniyeni ya methyl cellulose yokonzedwa bwino kuti igwiritsidwe ntchito popanga mankhwala, zakudya, zipangizo zomangira, zinthu zosamalira thupi, ndi ntchito zina zamafakitale. Mitundu iyi ikhoza kukhala ndi zinthu zomwe zimapangidwira kuti zigwirizane ndi zofunikira za ntchito zawo.
5. Magiredi Apadera:
   • Zina mwa zinthu zopangidwa ndi methyl cellulose zimapangidwa kuti zigwiritsidwe ntchito mwapadera kapena zimakhala ndi zinthu zapadera zomwe zimagwiritsidwa ntchito mwapadera. Zitsanzo zimaphatikizapo zinthu zopangidwa ndi methyl cellulose zomwe zimakhala ndi kutentha kokhazikika, zinthu zabwino zosungira madzi, zinthu zotulutsa zomwe zimayendetsedwa bwino, kapena zogwirizana ndi zowonjezera kapena zosungunulira zina.
6. Mayina a Malonda ndi Mitundu:
   • Zogulitsa za Methyl cellulose zitha kugulitsidwa pansi pa mayina osiyanasiyana amalonda kapena mitundu ndi opanga osiyanasiyana. Zogulitsazi zitha kukhala ndi makhalidwe ofanana koma zimatha kusiyana malinga ndi zomwe zafotokozedwa, mtundu, ndi magwiridwe antchito. Mayina odziwika bwino a methyl cellulose ndi awa: Methocel®, Cellulose Methyl, ndi Walocel®.

Zinthu zopangidwa ndi methyl cellulose zitha kugawidwa m'magulu kutengera zinthu monga mtundu wa kukhuthala, kuchuluka kwa kusintha, kulemera kwa mamolekyulu, mitundu yogwiritsidwa ntchito, mitundu yapadera, ndi mayina amalonda. Kumvetsetsa magulu awa kungathandize ogwiritsa ntchito kusankha mtundu woyenera wa methyl cellulose malinga ndi zosowa zawo komanso momwe amagwiritsidwira ntchito.
