Kuenzanisa kweMethocel uye Culminal:
Kuti tinzwisise mutsauko uripo pakati peMethocel neCulminal, tichaongorora zvakasiyana-siyana zveiyi cellulose ether zvigadzirwa, zvinosanganisira zvivakwa, maapplication, maitiro ekugadzira, nezvimwe:
1. Properties:
Methocel:
- Methocel mamakisi anogona kusiyana mu viscosity, dhigirii rekutsiva (DS), particle size, uye zvimwe zvivakwa.Iyi misiyano inoita kuti ive yakakodzera kune dzakasiyana siyana maapplication.
- Methocel inozivikanwa nekuchengeta kwayo mvura, kukora masimba, kunamira kwekunamira, uye firimu-kugadzira zvivakwa.
Culminal:
-Culminal mamakisi zvakare anoratidza mutsauko muzvivakwa, zvinosanganisira viscosity, DS, uye particle size, zvichienderana negiredhi chairo uye mashandisiro.
- Culminal cellulose ethers inozivikanwa nekuchengetedza mvura, kugona kukora, uye rheological control mune akasiyana magadzirirwo.
2. Zvikumbiro:
Ose Methocel neCulminal anoshandiswa mune anotevera maindasitiri uye maapplication:
-Kuvaka: Ivo vanowana kushandiswa kwezvinhu zvekuvakisa, zvakaita semataira anonamira, madhaka, magirotsi, uye ega-leveling makomisheni, kuwedzera zvivakwa zvakaita sekuchengetedza mvura, kushanda, uye kunamatira.
- Pharmaceuticals: Muindasitiri yemishonga, ese ari maviri anoshandiswa seanosunga, disintegrants, uye anodzorwa-asunungure vamiririri mupiritsi uye zvinodhaka dhizaini system formulations.
- Chikafu: Izvo zvinoshandiswa muindasitiri yechikafu kukora, kudzikamisa, uye kugadzirisa magadzirirwo ezvigadzirwa zvechikafu, senge sosi, madhirezi, uye zvinhu zvekubheka.
- Cosmetics: Zvese Methocel neCulminal zvinoshandiswa muzvizoro uye zvigadzirwa zvekuchengeta munhu kuti zvipe viscosity, magadzirirwo, uye emulsion kugadzikana.
3. Maitiro ekugadzira:
Maitiro ekugadzira eMethocel neCulminal anosanganisira matanho akafanana, sezvo ese ari ese cellulose ether.Matanho akakosha anosanganisira:
- Alkaline Kurapa: Iyo cellulose sosi inoiswa kune alkaline kurapwa kubvisa tsvina, kuzvimba cellulose fiber, uye kuita kuti iwanikwe kune mamwe magadzirirwo emakemikari.
- Etherification: Munguva iyi, serosi maketani anogadziridzwa makemikari nekuunza hydroxypropyl uye methyl mapoka.Aya magadzirirwo ane basa rekunyungudika kwemvura uye zvimwe zvinhu.
-Kugeza uye Neutralization: Chigadzirwa chinogezwa kubvisa makemikari asina kubatwa uye tsvina.Inobva yaitwa neutralized kuti iwane yaidiwa pH level.
-Kucheneswa: Maitiro ekuchenesa, anosanganisira kusefa uye kuwacha, anoshandiswa kubvisa chero tsvina yasara uye zvigadzirwa.
- Kuomesa: Iyo yakacheneswa cellulose ether inoomeswa kuderedza hunyoro hwayo, ichiita kuti ive yakakodzera kuenderera mberi nekugadziriswa uye kurongedza.
- Granulation uye Packaging: Mune zvimwe zviitiko, iyo yakaomeswa cellulose ether inogona kuita granulation kuti iwane inodiwa saizi uye kuyerera maitiro.Chigadzirwa chekupedzisira chinozoiswa mukati kuti chigovane.
4. Kuwanika Kwenharaunda:
Ose maviri Methocel neCulminal ane huvepo hwepasi rose, asi kuwanikwa kwemagiredhi chaiwo uye maumbirwo anogona kusiyana nedunhu.Vatengesi vemunharaunda nevashambadziri vanogona kupa akasiyana zvigadzirwa sarudzo zvichienderana nekudiwa kwedunhu.
5. Mazita eGrade:
Ose ari maviri Methocel neCulminal anopa akasiyana giredhi mazita, rimwe nerimwe rakagadzirirwa chaiwo mashandisirwo kana maitiro.Aya mamakisi anotarwa nenhamba uye mavara anoratidza zvimiro zvavo uye anokurudzirwa mashandisirwo.
Muchidimbu,Methoceluye Culminal zvigadzirwa zve cellulose ether zvinogovana zvakajairika maapplication mukuvaka, mishonga, chikafu, uye zvizorwa.Musiyano wekutanga pakati pawo uri mugadziri, magadzirirwo chaiwo echigadzirwa, uye kuwanikwa kwedunhu.Marudzi ese ari maviri anopa huwandu hwemagiredhi akagadzirirwa akasiyana maapplication, rimwe nerimwe riine misiyano yezvivakwa.Pakusarudza pakati peMethocel neCulminal kune chaiyo application, zvakakosha kubvunzana nevagadziri kana vatengesi kuti vaone chigadzirwa chakanyanya kukodzera uye kuwana ruzivo rwechigadzirwa uye rutsigiro rwehunyanzvi.
