Qhov sib txawv ntawm Mecellose thiab Hecellose

Mecellose thiab Hecellose yog ob hom cellulose ethers, uas feem ntau siv rau hauv ntau yam lag luam xws li tshuaj, khoom noj, kev tsim kho, thiab tshuaj pleev ib ce. Txawm li cas los xij, muaj qhov sib txawv ntawm lawv:

1. Cov Qauv Tshuaj: Mecellose thiab Hecellose yog cov khoom siv los ntawm cellulose, tab sis lawv yuav muaj kev hloov pauv tshuaj lossis kev hloov pauv sib txawv, ua rau muaj kev hloov pauv hauv lawv cov khoom thiab kev siv. Mecellose yog methyl cellulose ether, thaum Hecellose yog hydroxyethyl cellulose ether.
2. Cov Khoom: Cov khoom tshwj xeeb ntawm Mecellose thiab Hecellose tuaj yeem sib txawv nyob ntawm cov yam xws li lawv qhov hnyav molecular, qib kev hloov pauv, thiab qhov loj ntawm cov khoom me me. Cov khoom no tuaj yeem cuam tshuam rau cov yam xws li viscosity, solubility, thiab kev sib raug zoo nrog lwm cov tshuaj.
3. Daim Ntawv Thov: Txawm hais tias Mecellose thiab Hecellose siv tau ua cov khoom ua kom tuab, cov khoom khi, cov khoom ruaj khov, thiab cov yeeb yaj kiab, lawv yuav raug nyiam siv rau hauv ntau daim ntawv thov raws li lawv cov khoom tshwj xeeb. Piv txwv li, lawv yuav raug siv rau hauv cov tshuaj tsim tshuaj los tswj kev tso tawm tshuaj lossis hauv cov ntaub ntawv tsim kho kom txhim kho kev ua haujlwm thiab kev nplaum.
4. Cov Chaw Tsim Khoom: Mecellose thiab Hecellose tej zaum yuav tsim los ntawm cov chaw tsim khoom cellulose ether Lotte Fine Chemical, txhua tus muaj lawv tus kheej cov txheej txheem thiab cov khoom tshwj xeeb.

Nws yog ib qho tseem ceeb uas yuav tsum sab laj nrog cov ntaub ntawv khoom tshwj xeeb lossis tiv tauj lub chaw tsim khoom kom paub cov ntaub ntawv ntxaws ntxaws txog cov khoom thiab daim ntawv thov ntawm Mecellose thiab Hecellose kom txiav txim siab seb qhov twg zoo tshaj plaws rau ib qho kev siv tshwj xeeb.
