Hydroxyethyl cellulose (HEC), polymer isinganyungudike mumvura, inoshandiswa zvakanyanya mukuvaka masisitimu ekuputira madziro ekunze. Inonyanya kuvandudza kushanda kwependi, kuchengetedza mvura, hunhu hwekuenzana, uye hunhu hwekugadzira firimu, zvichiita kuti ive chinhu chakakosha mumasisitimu emazuva ano ekuputira madziro ekunze.
1.HEC ine hunhu hwakanaka hwekunyungudika kwemvura uye kukora kwayo, ichigadzira mhinduro yakasimba mumagadzirirwo emadziro ekunze akavakirwa mumvura. Mushure mekunyungudika, inowedzera zvakanyanya kunaka kwejira, ichidzivirira kudzika, kudonha, kana kuumbwa panguva yekushandiswa, nokudaro ichivimbisa kukora kwakafanana pamusoro pemadziro. Panguva imwe chete, kukora kweHEC kunodzora zvinobudirira hunhu hwegoridhe rethixotropic, ichichengetedza kugadzikana kwakati kana yakamira uku ichibvumira kuti ifambe zviri nyore panguva yekusanganisa kana kukwesha, zvichivandudza nyore kushandisa.
2.HEC inoratidza kuchengetedza mvura zvakanaka mumadziro ekunze. Munguva yekuomesa, kupwanyika kwemvura nekukurumidza kunogona kukonzera kupwanyika kwefirimu, kutsemuka, kana kusviba, zvichikanganisa kusimba kwemamiriro ekunze uye runako rwejira racho. HEC inogona kuburitsa hunyoro zvishoma nezvishoma, ichiwedzera nguva yekuvhurika kwejira uye zvichikonzera kuumbwa kwefirimu rakafanana uye rakakora, zvichivandudza kunamira uye kugara kwenguva refu mushure mekuomesa. Uyezve, HEC inogona kushanda pamwe chete nezvimwe zvinowedzera zvakaita sema dispersants uye ma leveling agents kuti iwedzere kugadzirisa kushanda kwejira uye kutsvedzerera kwepamusoro.
3.Mumachira ekunze emadziro, HEC inogonawo kuvandudza kugadzikana kwehurongwa hwekuputira. Machira ekunze emadziro anowanzo kuve masimbi akasimba, masisitimu akapararira, anowanzova sedimentation kana stratification. Mumasisitimu akavakirwa mumvura, HEC inogona kugadzira network structure, ichimisa uye ichiparadzira pigment ne filler particles, ichidzivirira sedimentation uye ichivimbisa kugadzikana kwenguva refu kwekuchengetedza. Izvi zvakakosha zvikuru kumachira ekunze emadziro anoshandiswa mukuvaka kukuru kana kutakurwa kure.
4.Huwandu hweHEC inowedzerwa pamwe nehuremu hwayo hwemamorekuru ndizvo zvinhu zvakakosha pakushandiswa. Kazhinji, HEC ine huremu hwakawanda inopa kukora kwakasimba uye mhedzisiro yekuchengetedza mvura, nepo HEC ine huremu hushoma ndiyo yakakodzera masisitimu ekuputira anoda kuyerera kwakanyanya uye kupfapfaidzwa. Chiyero cheHEC mumachira ekunze emadziro chinowanzova pakati pe0.1% ne0.5%, chakagadziridzwa uye chinogadziriswa zvichienderana nemhando dzakasiyana dzezvinhu zvepasi, nzira dzekushandisa, uye mamiriro ekunze. Kuwedzera kwakanyanya kweHEC kunogona kutungamira mukupenya kwakanyanya kwekuvhara, zvichikanganisa kushandiswa, nepo kusawedzera kwakakwana kuchiidzivirira kuita mabasa ayo ekuchengetedza mvura uye ekuenzanisa.
5.HEC inewo zvakanakira mukugadzira madziro ekunze asingakuvadzi nharaunda. Sechinhu chinobva kupolymer yemusikirwo chisiri cheionic, HEC ine chepfu shoma uye inogona kuora, ichizadzisa zvinodiwa zvemachira emazuva ano ekugadzira eVOC shoma (makemikari anoputika) uye mashandiro ezvakatipoteredza. Uyezve, kushandiswa kweHEC hakuburitse maitiro akakosha emakemikari ane pigments, fillers, uye additives, nokudaro zvichiratidza kubatana kwakanaka uye kugadzikana.
6.Kushandiswa kweHECMumasystem ekuputira madziro ekunze anonyanya kuoneka mukukora, kuchengetwa kwemvura, kushanda zvakanaka kwekushandisa, uye kugadzikana kwesystem. Kusarudzwa kwakakodzera kwemhando yeHEC uye chiyero kunogona kuwedzera kushanda, kuramba kwemamiriro ekunze, uye chitarisiko chependi, zvichipa rutsigiro rwakavimbika rwekutsvaga nekushandisa machira ekunze ekunze anoshanda zvakanyanya. Nekuwedzera kuri kuwedzera kwezvinodiwa zvekuchengetedza simba rekuvaka nekuchengetedzwa kwezvakatipoteredza, kushandiswa kweHEC mumachira ekunze emadziro kuchapararira zvakanyanya, uye mashandiro ayo uye kukosha zvicharamba zvichivandudzwa uye zvichiwedzerwa.
