Kuita uye kushandiswa kwehydroxyethyl cellulose

Zvimiro zveHydroxyethyl Cellulose

Izvo zvakakosha zve hydroxyethyl cellulose ndezvekuti inonyungudika mumvura inotonhora nemvura inopisa, uye haina gel zvinhu. Iine huwandu hwakawanda hwekutsinhanisa dhigirii, solubility uye viscosity, kugadzikana kwakanaka kwekushisa (pasi pe140 ° C), uye haigadziri gelatin pasi pemamiriro e acidic. kunaya kwemvura. Hydroxyethyl cellulose solution inogona kuumba firimu rakajeka, uye ine maitiro emhando isiri-ionic iyo isingabatanidzi neioni uye ine kuenderana kwakanaka.

① Kupisa kwakanyanya uye kunyungudika kwemvura: Kana ichienzaniswa nemethyl cellulose (MC) inonyungudika chete mumvura inotonhora, hydroxyethyl cellulose inogona kunyungudutswa mumvura inopisa kana mumvura inotonhora, uye haidonhedze pakupisa kana kufashaira, zvichiita kuti ive neyakasiyana siyana. solubility uye viscosity maitiro, uye kwete-thermogelling zvivakwa.

②Kushivirira kwemunyu: Sezvo isiri-ionic, inogona kugarisana neyakasiyana-siyana yemamwe mapolymer anonyungudika nemvura, ma surfactants, uye munyu. Naizvozvo, kana zvichienzaniswa neic carboxymethyl cellulose (CMC), hydroxyethyl cellulose ine nani kuramba munyu.

③Kuchengeta mvura, kuyera, uye kugadzira firimu: simba rekuchengetedza mvura rakapetwa zvakapetwa kaviri kupfuura yemethyl cellulose, uye ine yakanakisa kuyerera kwemutemo, yakanakisa kugadzira firimu zvimiro, kurasikirwa kwemvura, miscibility, uye inodzivirira colloid bonde.

Kushandiswa kwehydroxyethyl cellulose

Hydroxyethyl cellulose isiri-ionic mvura-soluble cellulose ether chigadzirwa, chinoshandiswa zvakanyanya mukugadzira machira, peturu, polymerization, mushonga, kushandiswa kwemazuva ese, bepa neingi, machira, ceramics, kuvaka, kurima uye mamwe maindasitiri. Iine mabasa ekukora, kubatanidza, emulsifying, kuparadzira uye kugadzikana, uye inogona kuchengetedza mvura, kuumba firimu uye kupa inodzivirira colloid effect. Iyo inonyungudika nyore nyore mumvura inotonhora uye inopisa mvura, uye inogona kupa mhinduro ine huwandu hwakawanda hweviscosity. Icho chiitiko mumakore achangopfuura. Imwe yeanokurumidza cellulose ethers.

1. Latex pendi

Hydroxyethyl cellulose ndiyo inonyanya kushandiswa mukobvu mu latex pendi. Pamusoro pekukora latex pendi, inogona zvakare emulsify, kuparadzira, kudzikamisa uye kuchengetedza mvura. Iyo inoratidzirwa neinoshamisa thickening mhedzisiro, yakanaka kukura kwemavara, kugadzira firimu uye kugadzikana kwekuchengetedza. Hydroxyethyl cellulose isiri-ionic cellulose inotorwa inogona kushandiswa muhupamhi pH renji. Iine kuwirirana kwakanaka nezvimwe zvinhu muchikamu (senge pigment, additives, fillers uye munyu). Makomboti akakora ne hydroxyethyl cellulose ane rheology yakanaka pamhando dzakasiyana dzekugera uye ari pseudoplastic. Nzira dzekuvaka dzakadai sebrashi yekuputira, roller coating uye spray coating inogona kugamuchirwa. Kuvakwa kwakanaka, kusiri nyore kudonha, sag uye kupfapfaidza, uye yakanaka yekuenzanisa chivakwa.

2. Polymerization

Hydroxyethyl cellulose ine mabasa ekuparadzira, emulsifying, kumisa uye kudzikamisa mu polymerization kana copolymerization zvikamu zvesynthetic resins, uye inogona kushandiswa seanodzivirira colloid. Iyo inoratidzirwa nekukwanisa kwakasimba kwekuparadzira, yakaonda chidimbu "firimu", yakanaka particle size, yunifomu particle shape, yakasununguka mhando, yakanaka fluidity, yakakwirira chigadzirwa kujeka uye nyore kugadzirisa. Nekuti hydroxyethyl cellulose inogona kunyungudutswa mumvura inotonhora nemvura inopisa, uye isina gelation tembiricha poindi, inonyanya kukodzera kune akasiyana mapolymerization maitiro.

Izvo zvakakosha zvemuviri zvimiro zvekuongorora kunaka kwekupararira ndeye pamusoro (kana yemukati) tension, interfacial simba uye gelation tembiricha yeaqueous solution. Aya masikirwo ehydroxyethyl cellulose anokodzera iyo polymerization kana copolymerization yemasynthetic resins. Hydroxyethyl cellulose ine kuenderana kwakanaka nemamwe mvura-soluble cellulose ethers uye PVA. Iyo composite system yakaumbwa inogona kuwana yakazara mhedzisiro yekudzidza kubva kune mumwe nemumwe. Zvigadzirwa zveresin zvakagadzirwa mushure mekusanganiswa hazvina kunaka chete, asi zvakare kuderedza kurasikirwa kwezvinhu.

3. Kuchera mafuta

Mukuchera nekugadzirwa kwemafuta, high-viscosity hydroxyethyl cellulose inonyanya kushandiswa seyakakora yekupedzisa zvinwiwa uye kupedza zvinwiwa. Yakaderera viscosity hydroxyethyl cellulose inoshandiswa semvura inoderedza kurasikirwa. Mumadhaka akasiyana-siyana anodiwa pakuchera, kupedzisa zvakanaka, kugadzira simende uye fracturing mashandiro, hydroxyethyl cellulose inoshandiswa seyakakora kuti iwane mvura yakanaka uye kugadzikana kwedhaka. Panguva yekuchera, inogona kuvandudza kukwanisa kutakura jecha rematope uye kurebesa hupenyu hwebasa rechibhorani. Muchikamu chakadzika chakasimba chekupedzisa mvura uye simende fluid, kurashikirwa kwemvura kwakanakisa kuderedza kushanda kwehydroxyethyl cellulose kunogona kudzivirira huwandu hwemvura kuti isapinda mudhaka remafuta kubva mumatope, uye inogona kuvandudza kugona kwekugadzira kweiyo mafuta layer.

4. Makemikari ezuva nezuva

Hydroxyethyl cellulose inyanzvi yekugadzira firimu, binder, thickener, stabilizer uye dispersant mu shampoos, hair sprays, neutralizers, hair conditioners uye cosmetics; muwashing powder Iyo ivhu redeposition agent. Hydroxyethyl cellulose inonyungudika nekukurumidza pakupisa kwepamusoro, iyo inogona kukurumidzira maitiro ekugadzira uye kugadzirisa kugadzirwa kwakanaka. Chinhu chiri pachena che detergent ine hydroxyethyl cellulose ndechekuti inogona kuvandudza kutsvedzerera uye silkiness yejira.

5. Kuvaka

Hydroxyethyl cellulose inogona kushandiswa muzvigadzirwa zvekuvaka senge kongiri musanganiswa, dhaka nyowani, gypsum plaster kana mamwe simende, nezvimwewo, kuchengetedza mvura panguva yekuvaka isati yagadzika nekuoma. Pamusoro pekuvandudza kuchengetwa kwemvura kwezvigadzirwa zvekuvaka, hydroxyethyl cellulose inowedzerawo kururamisa uye kuvhurika nguva yepurasita kana mastic. Inogona kuderedza ganda, kutsvedza uye kudonha. Nokudaro, kushanda kwekuvaka kunogona kuvandudzwa, kushanda kwekushanda kunogona kuwedzerwa, uye nguva inogona kuchengetedzwa. Panguva imwecheteyo, huwandu hwekuwedzera kweiyo stucco hunogona kuvandudzwa, nekudaro kuchengetedza zvigadzirwa.

6. Agriculture

Hydroxyethyl cellulose inoshandiswa mukugadzira emulsions yepesticide uye kumiswa, seyakakora yespray emulsions kana kumiswa. Inogona kuderedza kukukurwa kwemakemikari uye kuita kuti ibatanidzwe zvakasimba kumashizha emiti, nekudaro ichiwedzera mhedzisiro yefoliar spraying. Hydroxyethyl cellulose inogonawo kushandiswa semugadziri wekugadzira firimu mune mbeu yekuputira mbeu; semubhainda uye mugadziri wefirimu mukudzokorodza mashizha efodya.

7. Kugadzira mapepa uye inki yekudhinda

Hydroxyethyl cellulose inogona kushandiswa senge saizi yebepa nebhodhi uye seyakakora uye inomisa mumiriri kune ingi-yakavakirwa mvura. Mukugadzira mapepa, iwo epamusoro zvimiro zvehydroxyethyl cellulose zvinosanganisira kuenderana nemazamu mazhinji, resin uye inorganic munyu, furo rakaderera, kushandiswa kweokisijeni kushoma uye kugona kugadzira firimu repamusoro rakatsetseka. Iyo firimu ine yakaderera pamusoro permeability uye yakakwirira gloss, iyo inogona zvakare kuderedza mari. Pepa saizi ine hydroxyethyl cellulose, inogona kushandiswa kudhinda yemhando yepamusoro mifananidzo. Mukugadzirwa kweinki-based inki, mvura-based inki yakakora ne hydroxyethyl cellulose inomesa nekukasira, ine mavara akanaka ekupararira, uye haikonzeri kunamira.

8. Mucheka

Inogona kushandiswa sebhainda uye saizi mumiriri mukudhinda machira uye dhayi paste uye latex pendi; semukobvu wekuyera zvinhu kuseri kwemakapeti. Mugirazi fiber, inoshandiswa semugadziri wekugadzira uye binder; mumatehwe paste, inogona kushandiswa seyakagadziridza uye bhainda. Ipa yakafara viscosity renji yeaya machira kana anonamira, ita kuti iyo coating iwedzere yunifomu uye nekukurumidza, uye kunatsiridza kujeka kwekudhinda nekudhaya.

9. Ceramics

Inogona kushandiswa kugadzira mabhaidha akasimba-akasimba emakeramiki.

10. Mushonga wemazino

Inogona kushandiswa seyakakora mukugadzira mushonga wemazino.
