Sechinhu chinoshanda zvakawanda uye chisingakuvadzi nharaunda, cellulose ether yave ichishandiswa zvakanyanya munzvimbo dzakasiyana-siyana dzakadai sekuvaka, indasitiri yechikafu, indasitiri yemishonga, uye indasitiri yemachira. Pakati pazvo, cellulose ether yave ichikwezva kutariswa kwakawanda kwekushandiswa kwayo mukupenda kwemavara mumvura nekuda kwehunhu hwayo hwakasiyana hwakadai sekunyungudika kwemvura, kusakuvadza, uye kuora kwehupenyu.
Hunhu hwe ethers dze cellulose
Cellulose ethers dzinobva ku cellulose, iyo polymer yechisikigo inowanikwa zvakanyanya uye inogona kudzokororwa pasi rose. Dzinonyungudika mumvura, hadzina ionic, hadzina chepfu uye dzinoora, zvichiita kuti dzive sarudzo yakanaka kwazvo yekushandisa zvakawanda.
Mhando dzinonyanya kushandiswa dze cellulose ethers mu water-in-water coating dzinosanganisira hydroxyethyl cellulose (HEC), methyl cellulose (MC), uye carboxymethyl cellulose (CMC). Idzi cellulose ethers dzine hunhu hwakasiyana, asi dzese dzine hunhu hwakanaka hwekukora, kusunga uye kuchengetedza mvura, zvichiita kuti dzive dzakakodzera kushandiswa mu water-in-water coating.
Zvakanakira kushandisa cellulose ethers mukupenda kwemavara mumvura
- Kugadzikana Kwakawedzerwa: Chimwe chezvakanakira zvakakosha zvekushandisa cellulose ethers mukupenda kwemavara mumvura ndiko kugadzikana kwakanyanya kwekupenda. Cellulose ethers inobatsira kudzivirira zvidimbu zvepigment kuti zvisagare pasi petangi nekuzvirembedza mumvura.
- Kusviba kwakanyanya: Cellulose ethers inogona kuwedzera kusviba kwependi, zvichiita kuti iite gobvu uye ive nyore kuisa. Dzinobatsirawo kuti pendi iite kupfava, yakaenzana pamusoro, zvichivandudza kunaka kwependi.
- Kuchengeta mvura: Cellulose ethers inobatsira pendi kuchengetedza hunyoro, zvichiita kuti isaome nekukurumidza. Izvi zvinoita kuti pendi irambe ichishandiswa kwenguva yakareba, zvichipa mushandisi nguva yakakwana yekuisa pendi pamusoro.
- Kuenderana: Cellulose ethers inoenderana nezvimwe zvinhu zvakasiyana-siyana zvinoshandiswa mukupenda kwemavara mumvura, zvakaita semafirimu, defoamers uye zvinochengetedza.
- Inogarisana Nezvakatipoteredza: Cellulose ethers zvinhu zvinobva muchisikigo uye zvinoora, zvichiita kuti zvive sarudzo inogarisana nezvakatipoteredza yekupenda mavara mumvura.
Kushandiswa kwe cellulose ethers mukupenda kwemavara mumvura
- Madziro nedenga remukati: Mapendi ane ruvara rwemvura-mumvura ane cellulose ethers anogona kushandiswa pamadziro nedenga remukati mudzimba, mumahofisi nedzimwe nzvimbo dzemukati. Kugadzikana kwayo kwakagadziridzwa uye hunhu hwayo hwekuchengetedza mvura zvinoita kuti ive yakakodzera kushandiswa munzvimbo dzine hunyoro hwakawanda senge makicheni nedzimba dzekugezera.
- Madziro ekunze: Cellulose ethers inogona kushandiswawo mukupenda kwemadziro ekunze neruvara rwemvura. Anobatsira kupenda kunamira pamusoro zviri nani uye kupa magumo akasimba uye anogara kwenguva refu.
- Unyanzvi Hwakanaka: Cellulose ethers inogona kushandiswa muunyanzvi hwepamusoro kushandisa pigments dzeruvara rwemvura mumvura, dzakadai sema watercolor. Hunhu hwavo hwakanyanya hwekupenya uye hunhu hwekuchengetedza mvura zvinobvumira pendi kupararira nekusanganiswa zviri nyore papepa, zvichigadzira mavara akanaka uye akajeka.
mukupedzisa
Cellulose ethers zvinhu zvakanaka kwazvo zvekupenda mavara mumvura nekuda kwehunhu hwazvo hwakasiyana hwekunyungudika kwemvura, kusakuvadza uye kuora kwehupenyu. Zvinovandudza kugadzikana, kunaka, kuchengetedza mvura uye kuenderana kwependi, zvichiita kuti zvive nyore kushandisa uye zvinopa pendi yemhando yepamusoro.
Saka, ma ether e cellulose ane mukana mukuru mukushandiswa kwakasiyana-siyana kwakadai semadziro emukati, madziro ekunze uye hunyanzvi hwakanaka. Kushandiswa kwe ether e cellulose mukupenda kwemavara mumvura kunopa vashandisi sarudzo isingakuvadzi nharaunda uye yemhando yepamusoro iyo ine chokwadi chekupa mhedzisiro yakanaka.
