Coatings yagara iri chikamu chakakosha cheakasiyana maindasitiri, kubva kuvaka uye mota kusvika pakurongedza uye fenicha. Pendi dzinoshanda zvinangwa zvakawanda senge kushongedza, kuchengetedzwa, kuramba ngura uye kuchengetedza. Sezvo kudiwa kwemhando yepamusoro, yakagadzikana uye inoshamwaridzana majasi ari kuramba achikura, kushandiswa kwema cellulose ethers muindasitiri yekupfeka kwawedzera.
Cellulose ethers ikirasi yemapolymer anogadzirwa nekemikari shanduko ye cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro. Kugadziriswa kwe cellulose kunotungamira mukuumbwa kwema cellulose ethers, ane zvimiro zvakaita sekunyungudika kwemvura, viscosity, uye kugona kugadzira firimu.
Imwe yemabhenefiti makuru e cellulose ether kugona kwavo kuita semakobvu mukuputira maumbirwo. Ivo vanoita basa rakakosha mukuwana iyo inodiwa viscosity, kuve nechokwadi cheiyo coating application uye kuumbwa kwemafirimu. Uye zvakare, ivo vanopa yakagadziridzwa rheological zvimiro kune machira, senge nani kuyerera kwekudzora uye kuyera zvivakwa.
Pamusoro pekukora zvivakwa, cellulose ethers inopa mamwe akawanda mabhenefiti ekuputira maumbirwo. Semuyenzaniso, vanogona kuvandudza kusungirirwa kwejasi kune substrates, kuwedzera kudzivirira kwemvura kwemajasi, uye kuwedzera kusimba uye kuchinjika kwemafirimu ekuputira. Pamusoro pezvo, vane kunhuhwirira kwakaderera, huturu hwakaderera, uye vanowirirana nezvimwe zvakasiyana-siyana zvekuputira zvigadzirwa, zvinosanganisira pigment, extenders uye resin.
Cellulose ethers inoshandiswa zvakanyanya muindastiri yekuputira kune dzakasiyana siyana dzekushandisa, zvinosanganisira zvivakwa zvekuvaka, matanda ehuni, maindasitiri ekugadzira uye inki dzekudhinda. Mumachira ekuvaka, anoshandiswa kuzadzisa inodiwa sag kuramba, brushability uye kuenzana zvivakwa. Pamusoro pezvo, ivo vanowedzera kuramba kwemvura kweaya machira, ayo akakosha mukushandisa kwekunze. Mune machira ehuni, ivo vanopa iyo inodiwa yekunamatira uye kuchinjika kunodiwa pakuratidzwa kwekunze uye zvakare kubatsira kudzivirira kubva kune inokuvadza UV mwaranzi. Mumaindasitiri machira, cellulose ethers inovandudza abrasion kuramba yejasi, ichiita kuti ive yakakodzera kushandiswa pamichina inorema, pombi uye zvishandiso. Mukudhinda ingi, vanoita seviscosity modifiers, kuvandudza inki kutumira uye kudhinda kunaka.
Imwe yemamwe mabhenefiti akakosha e cellulose ether ndeye eco-hushamwari. Izvo zvinogona kudzokororwa uye biodegradable, zvichiita kuti ive inogadzika mbishi zvinhu. Pamusoro pezvo, iwo ane hushoma hunokanganisa nharaunda uye hutano hwevanhu nekuti haana chepfu uye haaburitse zvinokuvadza ne-zvigadzirwa panguva yekugadzira, kushandiswa kana kuraswa.
Cellulose ethers yakava zvinhu zvakakosha muindasitiri yekupfekedza, ichishanda zvakasiyana siyana zvinosanganisira kukora, kusamira kwemvura uye kunamatira. Yayo yakanakisa rheological zvimiro, kuenderana nezvimwe zvekuputira mbishi zvinhu uye kusimba kunoita kuti ive inoyevedza sarudzo kune vanogadzira coating. Nekukosha kuri kuwedzera kwekusimba uye eco-hushamwari, cellulose ethers inogona kuzonyanya kukosha muindasitiri yekupfeka mune ramangwana.
