Zvivakwa uye kushandiswa kwehydroxyethyl cellulose

Izvo zvakakosha zve hydroxyethyl cellulose ndezvekuti inonyungudika mumvura inotonhora nemvura inopisa, uye haina gelling zvivakwa. Iyo ine huwandu hwakasiyana hwekutsiva dhigirii, solubility uye viscosity. kunaya kwemvura. Hydroxyethyl cellulose solution inogona kuumba firimu rakajeka, uye ine maitiro emhando isiri-ionic iyo isingabatanidzi neioni uye ine kuenderana kwakanaka.

①Kupisa kwakanyanya uye kunyungudika kwemvura: Kuenzaniswa nemethyl cellulose (MC), inongonyungudika mumvura inotonhora, hydroxyethyl cellulose inogona kunyungudika mumvura inopisa kana mvura inotonhora. Yakasiyana-siyana solubility uye viscosity zvivakwa, uye isiri-thermal gelation.

②Munyu kuramba: Nekuda kweiyo isiri-ionic mhando, inogona kugarisana nemamwe mapolymer anonyungudika nemvura, ma surfactants uye munyu mune zvakawanda. Naizvozvo, kana zvichienzaniswa neic carboxymethyl cellulose (CMC), hydroxyethyl cellulose ine nani kuramba munyu.

③Kuchengetwa kwemvura, kuenzanisa, kugadzira firimu: simba rekuchengetedza mvura rakapetwa kaviri yemethyl cellulose, ine yakanakisa kuyerera kwemutemo uye yakanakisa kugadzira firimu, kuderera kwekurasikirwa kwemvura, kukanganisa, kudzivirira colloid bonde.

Kushandisa hydroxyethyl cellulose

Hydroxyethyl cellulose isiri-ionic mvura-soluble cellulose ether chigadzirwa, inoshandiswa zvakanyanya mukugadzira machira, petroleum, polymerization, mushonga, kushandiswa kwezuva nezuva, mapepa 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. Imwe yeanokurumidza cellulose ethers.

1 latex pendi

Hydroxyethyl cellulose ndiyo inonyanya kushandiswa mukobvu mumachira e latex. Pamusoro pekukora latex machira, inogona zvakare emulsify, kuparadzira, kudzikamisa uye kuchengetedza mvura. Iyo inoratidzirwa neinoshamisa thickening mhedzisiro, yakanaka kukura kwemavara, firimu-kugadzira pfuma uye kuchengetedza kugadzikana. Hydroxyethyl cellulose isiri-ionic cellulose inotorwa inogona kushandiswa muhupamhi pH renji. Iine kuenderana 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 dzakaita sekukwesha, kupfekedza roller, nekupfapfaidza zvinogona kushandiswa. Kuvakwa kwakanaka, hakusi nyore kudonhedza, kusaga nekupfapfaidza, uye kuenzana kwakanaka.

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 "firimu" yezvimedu, yakanaka particle size, yunifomu particle shape, yakasununguka mhando, yakanaka fluidity, yakakwirira chigadzirwa pachena uye nyore kugadzirisa. Nekuti hydroxyethyl cellulose inogona kunyungudutswa mumvura inotonhora nemvura inopisa, uye isina gelling tembiricha nzvimbo, inonyanya kukodzera kune akasiyana mapolymerization maitiro.

Izvo zvakakosha zvemuviri zvimiro zvekuongorora kunaka kweiyo dispersant ndeye pamusoro (kana interfacial) 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-inonyungudika cellulose ethers uye PVA. Iyo inoumbwa sisitimu inoumbwa nekudaro inogona kuwana yakazara mhedzisiro yekudzidza kubva kune mumwe nemumwe kusimba uye kuzadzisa kusimba kweumwe. Iyo composite resin zvigadzirwa hazvina kunaka chete, asi zvakare kuderedza kurasikirwa kwezvinhu.

3 kuchera mafuta

Mukuchera nekugadzirwa kwemafuta, high-viscosity hydroxyethyl cellulose inonyanya kushandiswa sevhisikifiri yekupedzisa mvura uye yekupedza zvinwiwa. Low viscosity hydroxyethyl cellulose inoshandiswa semvura inoderedza kurasikirwa. Mumadhaka akasiyana-siyana anodiwa pakuchera, kupedzisa, kuisa simende uye fracturing mashandiro, hydroxyethyl cellulose inoshandiswa seyakakora kuti iwane mvura yakanaka uye kugadzikana kwedhaka. Panguva yekuchera, inogona kuvandudza simba rekutakura jecha rematope uye kuwedzera hupenyu hwebasa rechibhorani. Muchikamu chakaderera chakasimba chekupedzisa zvinwiwa uye simende zvinwiwa, iyo yakanakisa kurasikirwa kwemvura yekudzikisa zvimiro zvehydroxyethyl cellulose inogona kudzivirira yakawanda yemvura kuti ipinde muoiri layer kubva mumatope, uye inogona kuvandudza kugona kwekugadzira kweiyo mafuta layer.

4 Kemikari yezuva nezuva

Hydroxyethylcellulose firimu rinoshanda rekare, binder, thickener, stabilizer uye dispersant mune shampoos, bvudzi sprays, neutralizers, conditioners uye cosmetics; mu detergent powders Iyo itsvina redeposition agent. Hydroxyethyl cellulose inonyungudika nekukurumidza pakupisa kwepamusoro, iyo inogona kukurumidzira maitiro ekugadzira uye kugadzirisa kugadzirwa kwakanaka. Chinhu chiri pachena chezvinosuka zvine hydroxyethyl cellulose ndechekuti inogona kuvandudza kutsetseka uye mercerization yemachira.

5 zvivakwa

Hydroxyethyl cellulose inogona kushandiswa muzvigadzirwa zvekuvaka senge kongiri musanganiswa, dhaka nyowani, gypsum plaster kana mamwe madhaka, nezvimwewo, kuchengetedza mvura panguva yekuvaka isati yagadzika nekuoma. Pamusoro pekuvandudza kuchengetwa kwemvura kwezvigadzirwa zvekuvaka, hydroxyethyl cellulose inogona zvakare kurebesa kururamisa uye kuvhurika nguva yestucco kana mastic. Inoderedza ganda, kutsvedza uye kupera simba. Izvi zvinogona kuvandudza mashandiro ekuvaka, kuvandudza kushanda zvakanaka, kuchengetedza nguva, uye panguva imwe chete kuwedzera huwandu hwekuwedzera kwehuwandu hwestucco, nekudaro kuchengetedza zvigadzirwa.

6 kurima

Hydroxyethyl cellulose inoshandiswa mupesticide emulsion uye kuturika maumbirwo semukobvu wepfapfaidzo emulsions kana kumiswa. Inogona kuderedza kudhonzwa kwemumiririri uye kuita kuti ibatanidzwe zvakasimba kune mashizha echirimwa, nekudaro ichiwedzera mhedzisiro yekupfapfaidza foliar. Hydroxyethyl cellulose inogonawo kushandiswa semugadziri wekugadzira firimu mumbeu yekuputira uye yekuputira agent; semubhainda uye mugadziri wefirimu mukudzokorodza mashizha efodya.

7 Pepa neIngi

Hydroxyethyl cellulose inogona kushandiswa senge saizi mumiririri pabepa uye bhodhi uye seyakakora uye inomisa mumiriri kune ingi-yakavakirwa mvura. Mukugadzira mapepa, iwo epamusoro zvimiro zvehydroxyethyl cellulose anosanganisira kuenderana nemazamu mazhinji, resin uye inorganic munyu, kuderera kwefuro, kuderera kweokisijeni kushandiswa uye kugona kugadzira firimu repamusoro rakatsetseka. Iyo firimu ine yakaderera pamusoro permeability uye yakasimba kupenya, uye inogona zvakare kuderedza mutengo. Pepa rakaenzana ne hydroxyethyl cellulose yemhando yepamusoro kudhindwa. Mukugadzirwa kweinki-based inki, mvura-based inki yakakora ne hydroxyethyl cellulose inooma nekukasira, ine mavara akanaka ekupararira, uye haiburitse sticking.

8 jira

Inogona kushandiswa sebhainda uye saizi mumiriri mukudhinda machira uye dhayi paste uye latex pendi; thickener yekuyera zvinhu kuseri kwekapeti. Mugirazi fiber, inoshandiswa seanoumba agent uye binder; mune dehwe pulp, inogona kushandiswa semodhifita uye binder. Inopa yakafara viscosity renji yeaya machira kana anonamira, zvichikonzera imwe yunifomu uye nekukurumidza kugadzika kwejasi uye nekunatsiridza kujeka kwekudhinda.

9 zveceramic

High simba binder yekugadzira makeramiki.

10 mushonga wemazino

Inogona kushandiswa seyakakora mukugadzira mushonga wemazino.
