Ko te Methylcellulose (MC) he rauemi polymer kua whakahiato matū, he etera cellulose whakarerekētanga i whiwhi mai i te methylating cellulose māori. Na ona ahuatanga motuhake o te tinana me te matū, ka whakamahia nuitia ki te hanga, ki te kai, ki te rongoa, ki te whakapaipai, ki te pepa me te paninga.
1. Te whakarōpūtanga ma te tohu whakakapinga
Ko te tohu whakakapinga (DS) e tohu ana ki te uara toharite o nga roopu hydroxyl i whakakapihia e nga roopu methyl ki ia wae huka i roto i te methylcellulose. E toru nga roopu hydroxyl i ia mowhiti huka o te ngota ngota cellulose ka taea te whakakapi e nga roopu methyl. Na reira, ko te tohu o te whakakapi o te methylcellulose ka rereke mai i te 0 ki te 3. E ai ki te tohu o te whakakapi, ka taea te wehewehe i te methylcellulose ki nga waahanga e rua: te teitei o te whakakapi me te iti o te whakakapi.
Te tohu teitei o te whakakapinga methylcellulose (DS> 1.5): Ko tenei momo hua he tohu nui o te methyl substitution, no reira he nui ake te hydrophobic, he iti ake te whakarewatanga me te pai o te wai. He maha nga wa e whakamahia ana i roto i nga taonga hangahanga, nga paninga me etahi atu waa e hiahia ana ki tetahi tohu o te hydrophobicity.
Te tohu iti o te whakakapinga methylcellulose (DS <1.5): Na te iti o te whakakapinga methyl, he nui ake te hydrophilic o tenei momo hua, he pai ake te whakarewatanga, ka taea te rewa ki te wai matao. Ko te methylcellulose iti-whakakapi e whakamahia nuitia ana i roto i nga umanga kai me nga mahi rongoa hei whakakaha, whakaehunga me te whakapumau.
2. Te whakarōpū ma te whakamahi
E ai ki te whakamahinga o te methylcellulose i roto i nga mara rereke, ka taea te wehewehe ki nga waahanga e rua: te methylcellulose ahumahi me te kai me te methylcellulose rongoā.
Ahumahi methylcellulose: I te nuinga o te wa e whakamahia ana i roto i te hanga, te paninga, te hanga pepa, te karaera me etahi atu ahumahi hei pupuhi, hei whakapiri, hei kiriata o mua, hei pupuri i te wai, me etahi atu. mauroa; i roto i te ahumahi whakakikorua, ka taea e te methylcellulose te whakanui ake i te pumau me te whakamararatanga o nga paninga.
Te kai me te rongoa methylcellulose: Na ona taonga kore-paitini me te kore kino, ka whakamahia te methylcellulose hei taapiri mo te kai me te rongoa. I roto i te kai, ko te methylcellulose he mea whakamaroke noa me te emulsifier ka taea te whakapumau i te hanganga kai me te aukati i te stratification, te wehenga ranei; i roto i te mara ho'oraa, ka taea te whakamahi methylcellulose rite te anga capsule, he kawe tarukino, a hoki he te mahi o te raau taero toitū-tuku. Ko tana kai me te haumaru ka tino rongonui te methylcellulose i enei mara e rua.
3. Te whakarōpūtanga ma te whakarewatanga
Ko te Methylcellulose te nuinga kua wehea ki nga waahanga e rua mo te whakarewatanga: te momo wairewa wai matao me te momo whakarewa pararopi.
Te wai matao wairewa methylcellulose: Ka taea te rewa tenei momo methylcellulose i roto i te wai matao hei hanga i te wairewa maramara, pokarekare i muri i te rewatanga. He maha nga wa e whakamahia ana i roto i nga umanga kai me te rongoa hei peera, he kiriata ranei o mua. Ko te memehatanga o tenei momo methylcellulose ka heke ki te piki haere o te pāmahana, na reira ka taea te whakamahi i tenei ahuatanga mo te whakahaere hangahanga ina whakamahia i roto i te umanga hanga.
Te methylcellulose whakarewa pararopi: Ko tenei momo methylcellulose ka taea te rewa i roto i nga whakarewa pararopi, ka whakamahia i te nuinga o nga wa i roto i nga peita, paninga me etahi atu mara ahumahi e hiahia ana i nga waahanga waahana. Na te pai o nga ahuatanga hanga kiriata me te aukati matū, he pai mo te whakamahi i raro i nga tikanga ahumahi kino.
4. Whakar
Ko te taumaha ngota o te methylcellulose he tino paanga ki ona ahuatanga o te tinana, ina koa te mahi pokey i roto i te otinga. E ai ki te taumaha ngota, ka taea te wehea te methylcellulose ki te momo pokey iti me te momo pokey teitei.
Te methylcellulose pokey iti: He iti te taumaha ngota me te iti o te pokey otinga. He maha nga wa e whakamahia ana i roto i te kai, te rongoa me te whakapaipai, te nuinga mo te whakaemulsification, te whakatārewatanga me te whakapakeke. Ka taea e te methylcellulose iti-viscosity te pupuri i te rere pai me te riterite, he pai hoki mo nga tono e hiahia ana ki nga otinga iti-pokey.
Ko te methylcellulose teitei-nui: He nui te taumaha ngota me te hanga i te otinga-nui-nui i muri i te whakakorenga. He maha nga wa e whakamahia ana i roto i nga taonga hangahanga, nga paninga me nga taputapu ahumahi. Ka taea e te methylcellulose teitei-nui te whakanui ake i te kaha o te miihini, te whakakakahu i te aukati me te piri o te otinga, na reira ka whakamahia nuitia i roto i nga rauemi e hiahia ana kia kaha te kaha me te kaha o te kakahu.
5. Te whakarōpūtanga ma te tohu o te whakarereke matū
Ko te Methylcellulose he pärönaki matū cellulose. E ai ki te tikanga whakarereke me te tohu, ka taea te wehewehe ki te methyl cellulose kotahi me te cellulose kua whakarerekehia.
Ko te methyl cellulose kotahi: e pa ana ki nga ethers cellulose he methyl-substituting anake. Ko tenei momo hua he ahua pumau, he matū hoki, a he pai te ahua o te whakarewatanga, te matotoru me te hanga kiriata.
Ko te cellulose kua whakarerekehia te hiato: I tua atu i te methylation, ka tukuna ano he matū, penei i te hydroxypropylation, te ethylation, me etahi atu, hei hanga i tetahi hua kua whakarereketia. Hei tauira, hydroxypropyl methylcellulose (HPMC) me te carboxymethyl cellulose (CMC). Ko enei cellulose kua whakarereketia he pai ake te wairewa, te parenga wera me te pumau, ka taea te urutau ki te whānuitanga o nga hiahia ahumahi.
6. Whakaritea ma te ahumahi tono
Ko te whakamahinga whanui o te methylcellulose ka taea te whakariterite i runga i ona ahuatanga tono i roto i nga umanga rereke.
Ko te ahumahi hangahanga methylcellulose: Ko te nuinga o nga mea e whakamahia ana i roto i nga mea e hangaia ana i te ciment me nga taonga gypsum hei pupuri wai me te matotoru. Ka taea e ia te whakapai ake i te mahi o nga rawa hanga, te aukati i te mate o te wai moata, me te whakanui ake i te kaha miihini o nga hua kua oti.
Te ahumahi kai methylcellulose: Hei whakaemulsifier, hei whakakaha me te whakapumau i te tukatuka kai. Ka taea e ia te aukati i te mate o te wai, te whakapai ake i te reka me te hanganga o te kai, me te whakanui ake i te oranga o te kai.
Ahumahi rongoa methylcellulose: Hei here papa, hei taonga tuku totika ranei mo nga raau taero. Ka taea hoki te whakamahi i te Methylcellulose ki te whakareri i nga rongoa o te kopu hei kawe rongoa haumaru me te whai hua.
Te ahumahi whakapaipai methylcellulose: I roto i nga hua tiaki kiri me nga mea whakapaipai, ka whakamahia te methylcellulose hei whakapakeke, whakaehunga me te moisturizer hei awhina i nga hua ki te hanga i te kakano ngawari me te maeneene i te wa e whakaroa ana te paanga o te makuku.
Hei whakarāpopototanga, he maha nga huarahi ki te whakarōpū i te methylcellulose, ka taea te whakarōpū i runga i ona ahuatanga hanganga matū, i runga ranei i ona waahanga tono me nga ahuatanga whakarewatanga. Ko enei tikanga whakarōpūtanga rereke ka awhina i a maatau ki te mohio ki nga ahuatanga me nga mahi o te methylcellulose, me te whakarato i te kaupapa ariā mo tana tono ki nga waahi rereke.
