Ndeapi marudzi akajairika emasero e cellulose ether? Ndeapi maitiro?

Cellulose eter iboka rakasiyana-siyana revazhinji vePolymers rinobva kuCellulose, polysaccharide inowanikwa muzvirimwa. Ivo vanoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, kusanganisira kuvaka, mishonga, chikafu, uye nechero zvoga, nekuda kwezvivakwa zvavo zvakasarudzika uye zvinoshamisa. Heano mamwe marudzi akajairika emasero ether uye hunhu hwavo:

1. MetHyl Cellulose (MC):
   • Hunhu:
     • MetHyl Cellulose inzvimbo inodonhedzwa mvura inotorwa kubva ku cellulose nekuibata ne methyl chloride.
     • Izvo zvinowanzoitika kusagadzikana, zvisingabvumirwe, uye zvisiri zvepfu, zvichiita kuti zviite kuti zvive zvekushandisa mune dzakasiyana siyana dzekushandisa.
     • MC inoratidzira yakanakisa mvura yekuchengetwa kwemvura, ichiita kuti ive yakanakisa yekuwedzera kweiyo coment-based-burns motsa, magirazi eGypsum anobva, uye maTile anomisheni.
     • Inovandudza basa rekushanda, kuderedza, uye nguva yakavhurika mune zvekuvaka, kubvumira kuve nyore kushandisa uye kuita zviri nani kuita.
     • MetHyl Cellulose inowanzoshandiswa seyekuita mumiririri, stabilizer, uye emulsifier mune zvigadzirwa zvekudya, mishonga yemishonga, uye cosmetics.
2. HydroxytHyl Cellulose (Hec):
   • Hunhu:
     • HydroxytHyl Cellulose inogadzirwa nekuita cellulose neEtralene oxide kuti isvike hydroxytHyl mapoka kune iyo cellulose backbone.
     • Izvo zvinonyangadza mumvura inotonhora uye mafomu akajeka, viscous mhinduro ine yakanakisa mvura yekuchengetedza midziyo.
     • HEC inowanzo shandiswa seyakanyanya, rheology modifier, uye nefirimu kugadzira mumiririri akasiyana-siyana ekushandisa, kusanganisira pendi, kuomerera, uye zvigadzirwa zvemunhu, uye mishonga.
     • Muzvivakwa zvekuvaka, hec inovandudza kushandira, Sag kuramba, uye kuunganidzira, zvichiita kuti zviite kuti zvishandiswe mukushandiswa kwemisangano uye neGypsum.
     • HEC zvakare inopa pseudoplastic maitiro, zvichireva viscosity inoderera pasi peShear kushushikana, kufambisa application iri nyore uye kupararira.
3. Hydroxyprupyl methyl cellulose (HPMC):
   • Hunhu:
     • Hydroxyprusyl methyl methyl cellelose ndeye cellulose etherode yakaburitswa nekuunza hydroxypropropropropropropropropropropropropropropropropropropropropropropropropropropropropyl uye methyl mapoka kune iyo cellulose backbone.
     • Inoratidza zvivakwa zvakafanana neese methyl cellelose uye hydroxytHevyl cellelose, kusanganisira yemvura solubility, firimu-kugadzira kugona, uye kuchengetwa kwemvura.
     • HPMC inozoshandiswa zvakanyanya mune zvekuvaka zvakadai seyakaomeswa anoshongedza, masimendi-akavakirwa, uye anozvimiririra mishonga yekuvandudza kushanda, kusungirirwa, uye kusawirirana.
     • Iyo inopa yakanakisa kurira, inosunga, uye inokanda midziyo mune zvemvura masisitimu uye inoenderana nezvimwe zvinowedzera zvinowanzo kushandiswa mukuvaka mafambiro.
     • HPMC inoshandiswawo mumishonga, zvigadzirwa zvekudya, uye zvinhu zvega zvega sedhizaira, kumhanyisa mumiriri, uye viscossity modifier.
4. Carboxymethyl Cellulose (cmc):
   • Hunhu:
     • CarboxyMethyl Cellelose etherulose ether inotorwa kubva kuCellulose nekuchibata neSodium Hydroxide uye monochloroacetic acid kuti aunze carboxymethyl mapoka ezvivakwa.
     • Izvo zvinonyangadza mumvura uye mafomu akajeka, viscous mhinduro zvine simba rakakora, kusimbisa, uye kudzokorora kwemvura.
     • CMC inowanzoshandiswa seyekani, binder, uye renhology modifier mumaindasitiri akasiyana-siyana, kusanganisira chikafu, mishonga, uye machira, uye pepa.
     • Muzvivakwa zvekuvaka, CMC dzimwe nguva zvinoshandiswa semumiriri wemvura mumutauriri wemvura uye zvakajairika, kunyangwe zvisinganyanye kuzivikanwa kupfuura mamwe ma cellulose etanter nekuda kwemutengo wakakwira uye zvakaderera zvine simba masisitimu emisangano.
     • CMC zvakare inoshandiswawo mune mishonga yemishonga seyemumiriri, piritsi binder, uye inodzorwa-inosunungura matrix.

Aya ndedzimwe mhando dzakajairika dze cellulose ether, imwe neimwe inopa yakasarudzika zvinhu uye mabhenefiti ezvekushandisa zvakasiyana. Paunenge uchisarudza cellulose ether yekunyorera chaiyo, zvinhu zvakadai sekusimbisa, zvevisikoka, kuenderana nevamwe vanowedzera, uye maitiro ekuita anodikanwa anofanirwa kuongororwa.
