Chii chinonzi low viscosity cellulose ether?

Low viscosity cellulose ether (low viscosity cellulose celloulose Cellulose ana vana vanoshandiswa zvakanyanya muminda dzakasiyana siyana maindasitiri. Ivo vanoshandiswa senhau, stabilizer, anomisheni, mafirimu mafirimu, nezvimwewo mune akawanda masisitari. Kuenzaniswa neakakwirira viscosity Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Cellulose Moncossity Moncossity Mune Solution, iyo inoita kuti vazoratidze zvakaringana mune zvimwe zviitiko zvakati.

1. Basic concepts

Cellulose ndiyo yakajairika yakanyanya polymer pasi pano, yakaumbwa neye glucose zvikamu mumadziro emasero. Kunyangwe zvisikwa zvisikwa zvakasarudzika mumvura uye zvisingarambidzi arermoplasticasity, cellulose etero inogona kugadzirwa kuburikidza nemakemikari kugadziridzwa. Izvi zvakagadziridzwa cellulose detivatives inoratidza yakasiyana solubility uye inoshanda zvivakwa mumifananidzo akasiyana siyana.

Cellulose eter inosanganisira marudzi mazhinji, akadai methyl cellerulose (HPMC), Carboxpropyl Cellulose (CarcosyProvers) Soliness-solentration mhinduro, kazhinji pakati pemamiriyoni mashoma emamiriyoni (MPA · (,) uye akati wandei maMironi masekondi.

2. Kugadzira maitiro

Cellulose Raw Zvinyorwa Sarudzo: Yakanyanya-Kuchenesa Wood Pulp kana Cotton Cellerose inowanzoshandiswa.
Alkalinization kurapwa: Cellulose inobatwa neAlkali (senge sodium hydroxide) kuti iite kuti ive yakawanda kana yakagadziridzwa nemiviri.
Eteraifitifitifitifiti yekuita: Sumo yekutsvagira vamiriri (senge methyl chloride, ethylene oxide, inobvumira mapoka ehuma
Kusarerekera uye kugeza: Chigadzirwa cheChiito chinorerekera uye chakashambwa kubvisa makemikari asina kugadziriswa uye ne-zvigadzirwa.
Kuomesa uye kupwanya: Iyo yakagadzirwa cellulose ether yakaoma uye yakapwanywa muhukuru hwaunoda.
Nekudzora mwero wekutsvaira uye maitiro ekuita, maitiro eViscosity of cellucose eterology anogona kugadziridzwa kuti awane zvigadzirwa-zveviscosity.

3. Hunhu

Yakadzika viscossity: Mhinduro yacho ine yakaderera viscosity, iyo iri nyore kupomba nekupuruzira, uye yakakodzera kune zvinoshandiswa zvinodiwa kuderera kuyerera kupokana.
Yakanaka solubility: inogona kunyungudika nekukurumidza mumvura kana organic sols kuti iite yunifomu mhinduro kana kupararira.
Yakanakisa firimu-inogadzira nzvimbo: inogona kuumba iyo yakasarudzika, yunifomu firimu, yakakodzera kuunganidza uye kuunganidza zvikumbiro.
Chemical inctness: ine yakanaka makemikari kugadzikana uye hazvisi nyore kuita nezvimwe zvinoshandiswa.
Biocompricompasile: Kazhinji isiri-ine chepfu, isiri-kutsamwisa, uye yakachengeteka pazvinhu zvese.

4. Nzvimbo dzekushandisa

Zvekuvaka
Muzvivakwa zvekuvaka, kuderera-viscosity cellulose ana ana vana vanoshandiswa senhau uye vamiririri vemvura-mongororo, vafirisa, uye vanomutsa. Ivo vanogona kuvandudza mashandiro ekuvaka, kuderedza shteringe marara, uye kuwedzera bond simba uye kusimba.

Coatings uye Inks
Low-viscosity cellulose ana anaiters inoshandiswa mumvura-yakavakirwa mvura uye inki mafambiro akaita senhau uye stabilizers. Ivo vanobatsira kugadzirisa zvivakwa, kugadzirisa zvivakwa zvekuvaka, uye kudzivirira sendimentation.

Pharmaceuticals uye cosmetics
Mune mishonga uye cosmetics, low-vcosity cellulose celloulose inogadzira machira ebirita, magetsi, etc. Ivo vanogona kupa midziyo yakanaka-yekuumba, kugadzikana, uye kusunganidzwa.

Indasitiri yechikafu
Muindasitiri yekudya, yakaderera viscosity cellulose maCellulose anaiters inowedzera zvekudya zvekunyepedzera, kusimbisa uye kugadzirisa mameseji, socy zvigadzirwa, sosi uye zvigadzirwa zvakabikwa.

Mafuta uye gasi
Muindasitiri yemafuta negesi, yakaderera viscosity cellulose ana ana vana vanoshandiswa senhau uye stabilizers yekurovedza mvura, kubatsira kudzora rheology uye kumiswa.

Iindasitiri yepepa
Low viscosity cellulose ana ana vana vanoshandiswa sehana uye vanoparadzira pulp muindasitiri yepepa kuti vavandudze zvivakwa uye kudhinda kwepepa.

5. Zvakanakira uye zvakashata

Yakadzika viscossity: nyore kubata uye maitiro, yakakodzera kune yakakwira kuyerera zviyero.
Yakanaka solubility: kukurumidza kuparara, nyore kugadzirira mhinduro.
Kuedza
Kudzivirirwa kwezvakatipoteredza: Vazhinji cellulose ana vana biodegradable uye kune zvakatipoteredza hushamwari.
Zvinokuvadza:

Mutengo wepamusoro: Nekuda kweiyo yakaoma yekugadzira maitiro, mutengo weyakaderera viscosity cellulose ma cellulose ana vana kazhinji kazhinji.
Kugadzikana kushoma: Pasi pemamwe mamiriro akanyanyisa, sekupisa kwakanyanya kana yakakwira pH, kugadzikana kunogona kukanganiswa.

6. Mangwana ivhu maitiro

Kuvandudza Maitiro Ekugadzira: Kuderedza mari yekugadzira uye kugadzirisa chigadzirwa mhando nekutsvagisa maitiro ekuita uye maitiro ekuyerera.
Inoshanda Kugadziridzwa: Kukudziridza Cellulose anaVile nematanho ezvakanyanya (sekusimbiswa kwakasimbiswa uye kwakakosha firimu-kugadzira zvivakwa zvekushandisa) kuti usangane zvinodiwa zvakasiyana.
Kudzivirirwa kwezvakatipoteredza uye kusimbiswa: kusimudzira kushandiswa kwezvinhu zvinotsigirwa uye zvakatipoteredza maitiro ekuderedza kukanganisa kwezvakatipoteredza.

Semunhu akakosha mheremalose anobva, akaderera-viscosity celloulose ana vatanhi zvakanyanya neindasitiri nekuda kweiyo yavo yakasarudzika viscosity zvivakwa uye huwandu hwakawanda hwekushandisa. Ivo havangotamba basa rakakosha muminda yetsika, asi zvakare inoratidza kugona kukuru mukubuda. Nekufambira mberi kwesainzi uye tekinoroji uye shanduko mumusika kudiwa, tarisiro yekushandisa yemasikati ye-viscosity cellulose mherenders ichava yakawedzera.
