Hydroxyethyl cellulose
Hydroxyethyl cellulose (HEC) isiri-ionic soluble cellulose etherderivativesizvo zvinogona kugarisana nemamwe akawanda-anonyungudika mapolima emvura, ma surfactants, uye munyu. HEC ine zvimiro zvekukora, kumiswa, kunamatira, emulsification, yakagadzikana firimu kuumbwa, kupararira, kuchengetedza mvura, anti-microbial kudzivirira uye colloidal kudzivirira. Inogona kushandiswa zvakanyanya mukupfeka, cosmetics, kuchera mafuta uye mamwe maindasitiri.
Zvinhu zvikuru zveHydroxyethyl cellulose(HEC)ndezvekuti inogona kunyungudutswa mumvura inotonhora nemvura inopisa, uye haina gel maitiro. Iine huwandu hwakawanda hwekutsiva, solubility uye viscosity. Iine kugadzikana kwakanaka kwekushisa (pasi pe140 ° C) uye haibereki pasi pemamiriro e acidic. kunaya kwemvura. Iyo hydroxyethyl cellulose mhinduro inogona kuumba firimu rakajeka, iro rine zvisiri-ionic maitiro asingadyidzani neion uye ane kuenderana kwakanaka.

CHaracteristics yeHEC
1.Kukora
HEC ndiyo yakanakira thickener yemakabati uye zvizorwa. Mumashandisirwo anoshanda, musanganiswa wekukora uye kumiswa, chengetedzo, dispersibility, uye kuchengetwa kwemvura kunoburitsa mamwe maitiro akanaka.
2.Pseudoplasticity
Pseudoplasticity inoreva pfuma iyo viscosity yemhinduro inoderera nekuwedzera kwekukurumidza. Latex pendi ine HEC iri nyore kushandisa nemabhurashi kana rollers uye inogona kuwedzera kutsetseka kwepamusoro, iyo inogonawo kuwedzera kushanda zvakanaka; shampoos ine HEC ine mvura yakanaka uye inoratidzika zvakanyanya, iri nyore kunyungudutsa, uye iri nyore kuparadzira.
3.Kushivirira kwemunyu
HEC yakanyatsogadzikana mu-high-concentration salt solutions uye haizoparari kuita ionic state. Inoshandiswa mu electroplating, pamusoro pezvikamu zvakaputirwa zvinogona kuva zvakakwana uye zvakajeka. Chinonyanya kukosha ndechekuti ichiri neine viscosity yakanaka kana ichishandiswa mulatex pendi ine borate, silicate uye carbonate.
4.Kugadzira firimu
Iyo firimu-inogadzira zvinhu zveHEC inogona kushandiswa mumaindasitiri mazhinji. Mumabasa ekugadzira mapepa, kuvhara neHEC-ine glazing agent inogona kudzivirira kupinda kwemafuta, uye inogona kushandiswa kugadzirira mhinduro kune mamwe maitiro ekugadzira mapepa; mukutenderera, HEC inogona kuwedzera elasticity ye fiber uye kuderedza kukuvadzwa kwemichina kwavari. Mune saizi, kudhaya uye kupedzisa maitiro ejira, HEC inogona kuita senge firimu rekudzivirira kwenguva pfupi. Kana kudzivirira kwayo kusingadiwi, inogona kushambidzwa kubva kune fiber nemvura.
5.Kuchengetedza mvura
HEC inobatsira kuchengetedza hunyoro hwehurongwa huri munzvimbo yakanaka. Nokuti shoma shoma yeHEC mumushonga wemvura inogona kuwana mvura yakanaka yekuchengetedza mvura, kuitira kuti hurongwa hunoderedza kudiwa kwemvura panguva yekuputira. Pasina kuchengetwa kwemvura uye kunamatira, simende dhaka inoderedza simba rayo uye kubatana, uye ivhu richaderedzawo plastiki yaro pasi pekumanikidzwa kumwe.
Applications
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 neyakakura thickening mhedzisiro, yakanaka kukura kwemavara, firimu-kuumba zvivakwa uye kuchengetedza kugadzikana. Hydroxyethyl cellulose isiri-ionic cellulose inotorwa uye inogona kushandiswa muhupamhi pH renji. Iine kuenderana kwakanaka nezvimwe zvinhu muchikamu (senge pigment, additives, fillers uye munyu). Makomboti akakora nehydroxyethyl cellulose ane rheology yakanaka uye pseudoplasticity pamitengo yakasiyana yekugera. Nzira dzekuvaka dzakadai sebrashi, roller coating uye spraying inogona kugamuchirwa. Kuvaka kwakanaka, hakusi nyore kudonhedza, sag nekupfapfaidza, uye chivakwa chekuyera zvakare chakanaka.
2.Polymerization
Hydroxyethyl cellulose ine mabasa ekuparadzira, emulsifying, kumisa uye kudzikamisa mu polymerization kana copolymerization chikamu chesynthetic resin, uye inogona kushandiswa seanodzivirira colloid. Iyo inoratidzirwa nekukwanisa kwakasimba kwekuparadzira, chigadzirwa chinoguma chine chidimbu chakatetepa "firimu", yakanaka particle size, yunifomu particle shape, yakasununguka chimiro, yakanaka fluidity, yakakwirira chigadzirwa pachena, uye nyore kugadzirisa. Sezvo hydroxyethyl cellulose inogona kunyungudutswa mumvura inotonhora uye mvura inopisa uye isina gelation tembiricha poindi, inonyanya kukodzera kune akasiyana mapolymerization maitiro.
Izvo zvakakosha zvemuviri zvimiro zve dispersant ndeye pamusoro (kana interfacial) tension, interfacial simba uye gelation tembiricha yayo aqueous 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 composite system inoumbwa neiyi inogona kuwana yakazara mhedzisiro yekuzadzisa kusasimba kweumwe neumwe. Iyo resin chigadzirwa chakaitwa mushure mekusanganiswa haina chete kunaka kwemhando, asiwo yakaderedza 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 sechinhu chinorasikirwa nemvura. Pakati pemadhaka akasiyana-siyana anodiwa pakuchera, kupedzisa, simenti uye fracturing mashandiro, hydroxyethyl cellulose inoshandiswa seyakakora kuti iwane mvura yakanaka uye kugadzikana kwedhaka. Munguva yekuchera, dhaka rinotakura simba rinogona kuvandudzwa, uye hupenyu hwebasa hwechibhorani hunogona kurebeswa. Mumvura yakadzika-yakasimba yekupedzisa zvinwiwa uye simende zvinwiwa, iyo yakanakisa yekurasikirwa kwemvura yekudzikisa kuita kwehydroxyethyl cellulose inogona kudzivirira yakawanda yemvura kuti ipinde mumafuta emafuta kubva mumatope uye kuvandudza kugona kwekugadzira kweiyo mafuta layer.
4.Zuva nezuva indasitiri yemakemikari
Hydroxyethyl cellulose firimu rinoshanda rekare, binder, thickener, stabilizer uye dispersant mune shampoos, bvudzi sprays, neutralizers, hair conditioners uye cosmetics; mu detergent powders Medium is a dirt redepositing agent. Hydroxyethyl cellulose inonyungudika nekukurumidza pakupisa kwakanyanya, iyo inogona kukurumidzira maitiro ekugadzira uye kunatsiridza kugadzirwa kwakanaka. Chinhu chiri pachena chezvinosuka zvine hydroxyethyl cellulose ndechekuti inogona kuvandudza kutsetseka uye mercerization yemachira.
5 Kuvaka
Hydroxyethyl cellulose inogona kushandiswa mukugadzira zvigadzirwa senge kongiri musanganiswa, ichangobva kusanganiswa dhaka, gypsum plaster kana mamwe madhaka, nezvimwewo, kuchengetedza mvura panguva yekuvaka isati yagadzika nekuoma. Pamusoro pekuvandudza kuchengetwa kwemvura kwezvigadzirwa zvekuvaka, hydroxyethyl cellulose inogona zvakare kuwedzera kururamisa uye kuvhurika nguva yepurasita kana simende. Inogona kuderedza ganda, kutsvedza uye kudonha. Izvi zvinogona kuvandudza mashandiro ekuvaka, kuwedzera kushanda zvakanaka, kuchengetedza nguva, uye panguva imwechete kuwedzera huwandu hwekuwedzera kwehuwandu hwedhaka, nekudaro kuchengetedza zvigadzirwa.
6 Zvekurima
Hydroxyethyl cellulose inoshandiswa mumishonga yekuuraya zvipembenene emulsion uye kuturika maumbirwo, semukobvu wekupfapfaidza emulsions kana kumiswa. Inogona kuderedza kudonha kwemedicament uye kuita kuti ibatanidzwe zvakasimba pashizha pamusoro pechirimwa, nokudaro ichiwedzera kushandiswa kwefoliar spraying. Hydroxyethyl cellulose inogonawo kushandiswa semugadziri wekugadzira firimu wembeu yekuputira machira; sechibhainda uye bhaisikopo rekugadzirazve mashizha efodya.
7 Pepa neingi
Hydroxyethyl cellulose inogona kushandiswa senge saizi mumiririri pabepa nekadhibhodhi, pamwe neyakakora uye yekumisa 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 yakasimba gloss, uye inogona zvakare kuderedza mutengo. Pepa rakanamirwa nehydroxyethyl cellulose rinogona kushandiswa kudhinda mifananidzo yemhando yepamusoro. Mukugadzirwa kweinki-based inki, mvura-based inki yakakodzwa nehydroxyethyl cellulose inooma nekukurumidza, ine mavara akanaka diffusibility, uye haakonzeri kunamatira.
8 jira
Inogona kushandiswa sebhainda uye saizi mumiriri mukudhinda machira uye kudhaya sizing agent uye latex coating; thickening agent yekuyera zvinhu kuseri kwekapeti. Mugirazi fiber, inogona kushandiswa seyakagadzira agent uye inonamira; mune yematehwe slurry, inogona kushandiswa seyakagadziriswa uye inonamira. Ipa zvakasiyana-siyana zveviscosity yezvipfeko izvi kana zvinonamatira, ita kuti kuvhara kuve kwakafanana uye kuomerera nokukurumidza, uye kunogona kuvandudza kujeka kwekudhinda nekudhaya.
9 Ceramics
Inogona kushandiswa kugadzira adhesives akasimba-akasimba emakeramiki.
