Ngā Āhuatanga o te Hua:

1. Āhua: He paura mā, he tata mā rānei te HEMC; kāore he kakara, kāore hoki he reka.

2. Wairewatanga: Ka taea te wairewa i te momo H i roto i te HEMC ki te wai i raro i te 60℃, ā, ka taea anake te wairewa i te momo L ki te wai matao. He rite tonu te HEMC ki te HPMC, ā, kāore e wairewa i roto i te nuinga o ngā whakarewa waro. I muri i te maimoatanga mata, ka marara te HEMC ki te wai matao me te kore e kohikohi, ā, ka rewa mārire, engari ka taea te wairewa tere mā te whakarerekē i tōna uara PH ki te 8-10.

3. Te pumau o te uara PH: Kāore te matotoru e rerekē nui i roto i te awhe 2-12, ā, ka heke te matotoru ki tua atu i tēnei awhe.

4. Te pai o te mahi: ko te tere o te paahitanga o te mata 80 he 100%; ko te tere o te paahitanga o te mata 100 he ≥99.5%.

5. Taumaha motuhake rūpahu: 0.27-0.60g/cm3.

6. Kei runga ake i te 200℃ te pāmahana pirau, ā, ka tīmata te tahu i te 360℃.

7. He nui ngā āhuatanga o te HEMC, he pakari te whakatārewatanga, he ngāwari te horapa, he piripono, he ngāwari te pokepoke, he pupuri wai me ētahi atu.

8. Nā te mea kei roto i te hua te rōpū hydroxyethyl, ka eke te pāmahana o te gel ki te 60-90℃. Hei tāpiri, he teitei te hydrophilicity o te rōpū hydroxyethyl, ā, he pai hoki te tere piri o te hua. Ina koa i roto i te hanganga wera me te pāmahana teitei i te raumati, he nui ake te pupuri wai o te HEMC i te methyl cellulose o te matotoru ōrite, ā, kāore i raro iho i te 85% te tere pupuri wai.

Te hiranga

Hei matū hohe mata, kei te hydroxyethyl methyl cellulose HEMC ēnei āhuatanga e whai ake nei, hei tāpiri atu ki te whakamātotoru, te whakatārewatanga, te here, te whakaemulsifying, te hanga kiriata, te marara, te pupuri wai me te whakarato i ngā colloid tiaki:

(1) Ka wairewa te Hydroxyethyl methyl cellulose HEMC i roto i te wai wera, i te wai matao rānei, ā, he whānuitia ōna āhuatanga wairewa me te matotoru, arā, te kore-werawera o te wai whakapūkara;

(2) Ka taea e te Hydroxyethyl methyl cellulose HEMC te noho tahi me te whānuitanga o ngā polymer wairewa-wai, ngā surfactants, me ngā tote, ā, he mea whakamātotoru pai mō ngā otinga electrolyte kukū-teitei;

(3) He kaha ake te pupuri wai o te HEMC i te methyl cellulose, ā, he kaha ake tōna pumau matotoru, tōna ngāwari ki te horapa, me tōna ātete ki te harore i te hydroxyethyl cellulose.

Tikanga whakarite otinga

(1) Tāpirihia he nui kua tohua o te wai ma ki te ipu;

(2) Tāpirihia te hydroxyethyl methyl cellulose HEMC me te whakaoho tere puhoi, ka whakaoho kia rewa katoa te hydroxyethyl methyl cellulose;

(3) I runga i ā mātou raraunga whakamātautau hangarau, e tino taunakihia ana kia tāpirihia i muri i te tāpiritanga o te polymer emulsion (arā, hydroxyethyl methyl celluloseHEMCkua konatunatua ki te ethylene glycol, ki te propylene glycol rānei).

I roto i te ahumahiwharengā rauemi,HEMC taumata hangahe pai mōpiripiri tāera, pāreti sima, moata whakauru maroke, whakataurite-ake, pāreti gypsum,He peita rapa, he mea here rauemi hanga, he mea hanga kē atu, he mea keri hinu, he mea tiaki whaiaro, he mea horoi, he mea whakamaroke, he mea tiaki, he mea piri, he mea whakaū, he mea whakatārewa hoki. Ka taea hoki te whakamahi hei kirikiri wai-whakaaro, hei rauemi matihiko, hei whakarite i ngā whakaritenga tuku-roa momo matihiko, ā, ka taea hoki te whakamahi hei mea whakaū i roto i ngā kai, me ērā atu mea.

Pte tatau me te rokiroki

(1) I tākaihia ki roto i te putea polyethylene hiato pepa-kirihou, i te putea pepa rānei, 25KG/pēke;

(2) Kia rere tonu te hau i roto i te wāhi rokiroki, karohia te whiti tika o te rā, me te waiho kia matara atu i ngā pūtake ahi;

(3) Nā te mea he hihiko te hydroxyethyl methyl cellulose HEMC, kaua e tukuna ki te hau. Me hiritia, me rongoa hoki ngā hua kāore i whakamahia, ā, me tiaki hoki i te makuku.
