Methyl cellulose ether

1. Nā hiʻohiʻona:

(1). Paʻa wai: MaiMethyl cellulose etherHiki i ka huahana ke komo i ka nui o ka wai, hiki iā ia ke mālama pono i ka wai i loko o ka mortar a me ka gypsum.

(2). Ka hoʻopaʻa ʻana i ke ʻano: ʻo kāna hoʻonā wai he mau waiwai viscoelastic kūikawā, hiki ke mālama i ke ʻano o nā huahana ceramic.

(3). Lubricity: Hiki i ka MC ke hōʻemi i ka helu friction a hoʻomaikaʻi i ka hana lubricating o nā huahana ceramic a me nā mea paʻa.

(4). Paʻa ka waiwai PH: ʻaʻole pili ka viscosity o ka hoʻonā wai e ka waikawa a i ʻole ka alkali. Noho paʻa kona ʻano wai ma luna o kahi ākea pH ākea, ma waena o 3.0 a me 11.0.

(5). Nā waiwai hana kiʻiʻoniʻoni: Hiki i ka MC ke hana i kahi kiʻiʻoniʻoni paʻa, ʻoluʻolu a ʻike ʻia me ke kūpaʻa ʻaila maikaʻi.

2.Molecular formula:

N: degere o ka polymerization;R: -H, -CH3 a i ʻole CH2CHOHCH3

3. Nā Pono Kino a me Kemika

Keʻano hoʻoheheʻe:

E puhi mua i ka wai i 80-90 ° C, e hoʻohui mālie i ka MC ma lalo o ka hoʻoulu ʻana mau, e kali i ka hāʻule ʻana o ka mahana, a laila e hoʻomaʻalili e hana i kahi ʻano wai like ʻole. A i ʻole e hoʻohui i hoʻokahi hapakolu i ʻelua hapakolu o ka wai i makemake ʻia ma mua, wela i ka 80-90 ° C, e hoʻohui mālie i ka MC ma lalo o ka hoʻoulu ʻana mau, ma hope o ka hoʻonui ʻana, e hoʻohui i ke koena wai anuanu, a hoʻomaha.
