Iyo HEC, kana Hydroxyethyl cellulose, inobata basa rakakosha mukuputira, ichishanda akasiyana mabasa anobatsira mukuita uye kunaka kwechigadzirwa chekupedzisira. Coatings anoiswa kune pamusoro pezvinangwa zvakasiyana, zvinosanganisira kudzivirira, kushongedza, kana kusimudzira kushanda. Mukati meichi chinyorwa, HEC inoshanda sechinhu chinowedzera chinowedzera chine zvivakwa zvinobatsira mukugadzira uye kushandiswa kwemajasi.
1.Thickening Agent:
Rimwe remabasa ekutanga eHEC mukupfeka ibasa rayo seyakakora mumiriri. HEC i polymer inonyungudika mumvura inoratidza kugona kuwedzera viscosity yeaqueous solutions. Mukuputira magadzirirwo, inobatsira mukuzadzisa inodiwa kuenderana uye rheological zvivakwa. Nekudzora viscosity, HEC inova nechokwadi kumiswa kwakaringana zvidimbu zvakasimba, kudzivirira kugadzirisa, uye kufambisa yunifomu kushandiswa kwejasi pane substrate. Hunhu uhwu hunonyanya kubatsira mukuumbwa kwependi uko kuchengetedza viscosity chaiyo kwakakosha kuti zvive nyore kushandisa uye ukobvu hwehuputi hwaunoda.
2.Stabilizer uye Suspension Aid:
HEC inoshandawo seyakagadzika uye kumiswa rubatsiro mukugadzira machira. Inobatsira kudzikamisa pigment, mafirita, uye zvimwe zvinowedzera mukati meiyo coating system, kudzivirira kugadzika kwavo kana kupatsanura panguva yekuchengetedza uye kushandisa. Ichi chivakwa chinovimbisa kuti iyo yekupfekedza inochengetedza homogeneity uye kufanana kwayo, ichiwedzera kuita kwayo uye kutaridzika kwayo. Nokuvandudza kugadzikana kwekugadzirisa, HEC inobatsira pakushanda kwenguva refu uye kusimba kwekuputira.
3.Kuyerera kwakavandudzwa uye kudzikamisa:
Kuvapo kweHEC mukuputira kunosimudzira kuyerera kwakavandudzika uye kuenzanisa maitiro. Nekuda kweizvozvo, machira ane HEC anoratidza zvirinani wetting zvivakwa, zvichivabvumira kupararira zvakaenzana pamusoro pe substrate surface. Izvi zvinosimudzira kutaridzika kwese kwenzvimbo yakavharwa nekudzikisa kuremara senge brashi mamaki, ma roller mamaki, kana kufukidzwa kusina kuenzana. Iyo yakagadziridzwa yekuyerera uye yekuyera zvivakwa inobatsirawo mukugadzirwa kweyakapfava uye yunifomu kupera, inosimudzira inoyevedza kukwezva kwenzvimbo yakavharwa.
4.Kuchengeta Mvura uye Kugadzira Mafirimu:
HEC inobatsira mukuchengetedza mvura mukati mekugadzirisa kwekuvhara, iyo inokosha pakugadzirwa kwemafirimu kwakakodzera. Nekuchengetedza hunyoro, HEC inofambisa kubuda kwemvura zvishoma nezvishoma kubva pakuputira panguva yekuomesa kana kurapa maitiro. Iyi inodzorwa evaporation inovimbisa kuomeswa kwakafanana uye inosimudzira kuumbwa kweinoenderera uye yakabatana firimu pane substrate. Kuvapo kweHEC mufirimu kunobatsirawo kuvandudza kusungirirwa kwayo kune substrate, zvichiita kuti igare yakasimba uye inogara kwenguva refu.
5.Kuenderana uye Kusarudzika:
HEC inoratidza kuenderana kwakanakisa neyakasiyana-siyana yekupfekedza zvinhu, kusanganisira pigment, binders, solvents, uye zvimwe zvinowedzera. Izvi zvakasiyana-siyana zvinobvumira kubatanidzwa kwayo kunoshanda mumhando dzakasiyana dzemachira, kusanganisira pendi-yakavakirwa mvura, zvinonamira, zvisimbiso, uye machira epamusoro. Ingave ichishandiswa mumachira ekuvaka, kupedzisa kwemotokari, kana maindasitiri machira, HEC inopa inowirirana kuita uye kuenderana, zvichiita kuti ive sarudzo inosarudzika kune vanogadzira mumaindasitiri akasiyana.
6.Rheology Modifier:
Kupfuura kukora kwayo zvimiro, HEC inoshandawo seye rheology modifier mune coating formulations. Iyo inokanganisa mafambiro ekuyerera uye viscosity chimiro chejasi, ichipa shear-kutetepa kana pseudoplastic zvivakwa. Iyi rheological control inobvumira kushandiswa kuri nyore kwejasi, sezvo inogona kupararira nyore nyore kana kupfapfaidzwa pane substrate. Pamusoro pezvo, HEC inobatsira mukudzikisira kudonha uye kudonha panguva yekunyorera, zvichibatsira kune inoshanda uye mushandisi-inoshamwaridzika yekuputira maitiro.
7.Enhanced Stability uye Sherufu Hupenyu:
Coatings ane HEC anoratidza kusimba kwakawedzera uye yakawedzerwa hupenyu hwesherufu nekuda kwekugona kwayo kudzivirira kupatsanurwa kwechikamu, sedimentation, kana syneresis. Nokuchengetedza kutendeseka kwekugadzirisa, HEC inovimbisa kuti chifukidzo chinoramba chichishandiswa kwenguva yakareba, kuderedza marara uye nyaya dzine chokuita nekuchengetedza. Uku kugadzikana kunonyanya kukosha mukutengesa kwekutengesa uko kunoenderana kushanda uye kunaka kwechigadzirwa zvakakosha.
HEC inobata basa rakasiyana-siyana mukugadzira machira, ichipa mabhenefiti akadai sekukora, kudzikamisa, kunatsiridza kuyerera uye kuenzanisa, kuchengetwa kwemvura, kuenderana, rheology kugadziridzwa, uye kuwedzera kugadzikana. Kushanda kwakasiyana-siyana uye kushanda kwayo kunoita kuti ive yekuwedzera inodiwa mukugadzirwa kweakasiyana machira, zvichibatsira mukuita kwavo, kusimba, uye kukwezva. Sezvo kudiwa kwemhando yepamusoro yekupotera kuri kuramba kuchikura, kukosha kweHEC mukuwana inodiwa yekugadzira zvivakwa kunoramba kwakakosha muindasitiri yekupfeka.
