He aha te hydroxyethyl methyl cellulose (HEMC)?

 Hydroxyethyl methylcellulose(HEMC) e mohiotia ana ko te methylhydroxyethyl cellulose (MHEC).He matūriki ma, he hina hina, he matūriki ma kowhai ranei.He etera cellulose kore katote i whiwhi ma te taapiri i te ethylene oxide ki te methyl cellulose.He mea hanga mai i nga polymers ka taea te whakahou ano i te rakau rakau, te miro ranei, a ka taea te whakamahi HEMC hei kaihoko pupuri wai tino pai, hei whakapiri me te kiriata hanga kiriata, stabilizer, me etahi atu. te keri, te hanga me te hanga, te peita me te paninga, nga rongoa, aha atu.HEMCka taea te whakarereke kia rite ki nga whakaritenga a nga kaihoko, a, i muri i te whakarereketanga, he pai tonu te aukati ki te sagging me te pai o te mahi.E hiahia ana ki te whakamahiHEMCmo nga kaupapa ahumahi?Tena koa whakapā atu ki tetahi kaiwhakarato pono ohydroxyethyl methyl celluloseki te whiwhi i te hokohoko pai.

Ko nga ahuatanga o te HEMC

HEMChe momo mahi.Kei roto ko:

1. Te ahua

 HEMChe ma, he kowhai marama, he kowhai ma, he ma hina ranei.

2. Wairewa

HEMChe wairewa ki te wai (mao, wera ranei).AhakoaHEMChe tarewa i roto i te nuinga o nga whakarewa pararopi, he wairewa i roto i nga whakarewa pararopi rua me nga punaha wai whakarewa pararopi.

Ko tona kukū teitei e whakawhirinaki ana ki te pokey, me tona memehatanga he rereke ki te pokey.Ko te iti o te pokey, ka nui ake te whakarewatanga, me te rereke.

3. Te pumau o te pH

 HEMChe pumau i roto i te awhe o te 3.0-11.0 me te kore e pa ana tona pokey, engari ka nui ake i tenei awhe ka whakaitihia tona pokey.

4. Te whakakino

 HEMChe matū korekore e whakamahia whānuitia ana i roto i te kai me te rongoa na te kore e kaha ki te paopao.

5. Mahi mata

Na tona mahi kaha o te mata i roto i nga wairewa wai, ka taea te whakamahi hei dispersant, kaitiaki, me te emulsifier.

6. Atete harore

I roto i te rokiroki mo te wa roa,HEMChe pai te pumau o te pokey, na reira he pai te aukati i te pokepokea ai.

He teitei ake i tera o te hydroxyethyl cellulose tona kaha mold mold.

7. Te pupuri wai

 HEMCka waiho hei kaihoko pupuri wai whai hua na te nui o te pokey i roto i nga wairewa wai.

He nui ake te kaha pupuri wai i tera o te methyl cellulose.

8. Te ihirangi pungarehu

Ko te tukanga whakarite oHEMCka whakamahi i te horoi wai wera, ka iti rawa te pungarehu.

9. Ngaariki conductive whakapiringa

Ina teHEMCka whakamahana te otinga ki tetahi pāmahana, ka heke tona marama, ka hanga parataiao me te ra, engari ki te whakamataohia, ka hoki ano ki te ahua taketake o te otinga.

Whakamahinga noa oHEMC

 HydroxyethylmethylcelluloseKa taea te whakamahi hei:

Ø AdhesiveØ Tiaki colloidØ ThickenerØ Kaitohu hanga Kiriata Whakapaipai WhakahinuhinuØ Kaituku whakatārewatanga

Nga tono Ahumahi oHEMC

 HEMCKei te whakamahia nuitia i roto i nga ahumahi e whai ake nei:

·Ko te Whakakotahitanga · Karaika · Taonga · Hanganga · Kai me te Inu · Nga rongoa · Peita me te paninga · Waituhi me te keri hinu

Ka rite ki te korero i mua,hydroxyethyl methylcellulose (HEMC) he takenga o te methylcellulose.He etera cellulose kore katote i hangaia mai i nga rawa miro tino parakore.HEMCKo te pupuri i te wai me te kaha ki te whakapakeke he pai mo te peita taherapa wai, te waituhi me te keri hinu, nga rawa hanga whare, me etahi atu.HEMCmai i nga kaiwhakarato rongonui o te hydroxyethyl methyl cellulose ka taea te whakarite kia whiwhi koe i nga hua e tika ana mo te whakamahi whaiaro, ahumahi ranei.
