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 taiao hou penei i te penupenu rakau, te miro ranei, a ka taea te whakamahi HEMC hei kaihoko pupuri wai tino pai, te whakapiri me te kaiwhakatangi kiriata, te whakapumau, me etahi atu. te keri, te hanga me te hanga, te peita me te paninga, te 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.
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 noho 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 whakamahia 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 Mahinga 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 o te matotoru e pai ana mo nga 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.
