Koeke hanga HEMC

Koeke hanga HEMCHydroxyethylMethylCellulosee mohiotia ana ko Methyl Hydroxyethyl Cellulose(MHEC), hehe paura ma, he ma ranei, he hongi, he kore reka, he wairewaI roto i te wai wera me te wai matao. Ka taea te hanga HEMCKa whakamahia hei ciment, gypsum, kotakota gelling agent, wai pupuri wai, he pai rawa te whakauru mo nga rawa hanga paura.

Āhuatanga Hua:

1. Te ahua: HEMC he ma, he tata ma te paura; kore kakara me te reka.

2. Wairewa: Ko te momo H i roto i te HEMC ka taea te whakakore i roto i te wai i raro iho i te 60 ℃, a ko te momo L ka taea anake te whakakore i te wai makariri. He rite tonu te HEMC ki te HPMC, a, karekau e rewa i roto i te nuinga o nga whakarewa pararopi. I muri i te maimoatanga o te mata, ka marara te HEMC i roto i te wai matao me te kore e whakahiato, ka memeha haere, engari ka tere te whakakore ma te whakatika i tana uara PH ki te 8-10.

3. Te pumau o te uara PH: He iti te rereke o te pokey i roto i te awhe o te 2-12, ka heke te pokey ki tua atu i tenei awhe.

4. Fineness: te tere haere o 80 mata ko 100%; te tere haere o 100 mata ko ≥99.5%.

5. Te taumahatanga teka: 0.27-0.60g/cm3.

6. Kei runga ake i te 200 ℃ te pāmahana whakapoapoa, ka timata te wera ki te 360 ​​℃.

7. He nui te matotoru o te HEMC, te pumau o te whakatārewatanga, te whakamararatanga, te whakakotahitanga, te moldability, te pupuri wai me etahi atu ahuatanga.

8. Na te mea kei roto i te hua te roopu hydroxyethyl, ka eke te pāmahana reera o te hua ki te 60-90 ℃. I tua atu, he nui te hydrophilicity o te roopu hydroxyethyl, he pai hoki te reiti herenga hua. Ina koa i roto i te hanganga wera me te teitei o te wera i te raumati, he nui ake te pupuri o te wai o te HEMC i te methyl cellulose o te pokey kotahi, a ko te reeti pupuri wai kaore i te iti iho i te 85%.

Koeke Hua

Hiranga

Hei kaihoko kaha mata, ko te hydroxyethyl methyl cellulose HEMC nga ahuatanga e whai ake nei i tua atu i te matotoru, te aukati, te honohono, te whakaemulsifying, te hanga kiriata, te whakamararatanga, te pupuri wai me te whakarato i nga kohinga whakamarumaru:

(1) Hydroxyethyl methyl cellulose HEMC he wairewa i roto i te wai wera, matao ranei, na te mea he maha nga ahuatanga o te whakarewatanga me te viscosity, ara, te waiariki kore;

(2) Ka taea e te Hydroxyethyl methyl cellulose HEMC te noho tahi me te tini o etahi atu polymers wairewa-wai-wai, surfactants, me te tote, a he mea tino pai mo nga otinga electrolyte teitei;

(3) He kaha ake te pupuri wai o te HEMC i te methyl cellulose, a, he kaha ake te pumau o te pokey, te marara, me te koriri i to te hydroxyethyl cellulose.

Te tikanga whakarite otinga

(1) Taapirihia te nui o te wai ma ki te ipu;

(2) Tāpirihia te hydroxyethyl methyl cellulose HEMC i raro i te tere tere o te whakaoho, me te whakaoho kia rewa katoa te hydroxyethyl methyl cellulose;

(3) I runga i o maatau raraunga whakamatautau hangarau, ka tino taunakihia kia taapirihia i muri i te taapiri o te polymer emulsion (arā, hydroxyethyl methyl cellulose.HEMChe mea whakauru-mua ki te ethylene glycol, propylene glycol ranei).

Ustau

I roto i te ahumahiwharerauemi,hangahanga kōeke HEMChe pai mote whakapiri tira, te raima sima, te kumete whakauru maroke, te whakamaarama whaiaro, te raima gypsum,peita taherapa, herenga rauemi hanga whare, etahi atu mara hanga, keri hinu, hua tiaki whaiaro, horoi horoi, me era atu, te nuinga o te whakamahia hei whakamarumaru, hei whakamarumaru, hei whakapiri, hei whakapumau, me nga apiha whakatārewa ka taea hoki te whakamahi hei gel hydrophilic, rauemi matrix. , te whakarite i nga whakaritenga tuku-a-tuuturu-momo-momo, ka taea hoki te whakamahi hei whakapumau i roto i nga kai, aha atu.

Packaging me te rokiroki

(1) Kiia i roto i te peeke polyethylene hiato pepa-kirihou peeke pepa ranei, 25KG/peeke;

(2) Kia rere te hau ki te waahi rokiroki, karohia te ra tika, kia matara atu i nga puna ahi;

(3) Na te mea ko te hydroxyethyl methyl cellulose HEMC he hygroscopic, kaua e pa ki te hau. Ko nga hua kaore i whakamahia me hiri me te rongoa, ka tiakina mai i te makuku.
