Hydroxyethyl methyl cellulose

Ko te Hydroxyethyl methyl cellulose (HEMC) i whakaritea ma te whakauru i te waikawa o te waikawa ki te methyl cellulose (MC). Ko tana manaakitanga tote he pai ake i te polymer kaore i whakarerekehia, a ko te mahana o te gel o te methyl hydroxyethyl cellulose i teitei ake i te methyl cellulose.

Ⅰ. Motuhake

1. Te Ahua: Ma te paura ma, rite ranei, kaore he maheni miihini, kaore he kakara me te koretake

2. Te pāmahana o te kiri (℃): 60-90

3. Te wai wai （Wt%）: ≤5.0

4. Ihirangi pungarehu （Wt%）: ≤5.0

5.HP: 5.0-8.0

6. Te Tika: ≥80 Mesh

7. Te pehu （mPa.s, 2% wairewa wai, 20 ± 0.2 ℃）: 100000-20000

Ⅱ.Whakaahua te mahi hangarau

1. Te memehatanga: te tauira H i te HEMC ka taea te rewa i roto i te wai matao me te wai wera, i te mea ko te tauira L ka rewa noa i te wai makariri, i te kore e wairewa te HEMC i te nuinga o nga whakarewa waro. Ka marara te mata o te rongoa HEMC i te wai makariri kaore e whakakao. Heoi, ka taea te rewa tere ma te whakatika i tona uara pH ki te 8-10

2. Te pumau o te PH: Ko te uara pH i te whānuitanga o te 2-12 huringa viscosity he iti, i tua atu i tenei waahanga ka whakahekehia te piripiri

3. Ko te HEMC nga ahuatanga o te matotoru, te aukati, te marara, te taatai, te auhau, te hanga kiriata me te pupuri wai, me te kaha o te wai e kaha ake ana i te methylcellulose. Te pumau maatauranga, te parekura ngawari me te marara he pai ake i te cellulose hydroxyethyl

Ⅲ. Te whakamahi me te tūpato

Kei te whakamahia whānuitia te HEMC ki te whakakikorua i te taumanu-a-wai, te hanga me te hanga whare, te waituhi taarua, te keri hinu, etc.

. Mōkihi me te penapena

1.Kia tenei hua te pepa raraunga haumaru me nga raraunga tuku urunga haumaru

2.Ko tenei hua kua kikii ki te 25 kg pepa kraft me te peera kiriata kirihou kua makaia

3. Toa i te wahi maroke, kia whai whakaaro ki te pono o te makuku
