Cellulose ethers anowanzo shandiswa additives mu gypsum mortars kunatsiridza zvivakwa zvavo.Gypsum dhaka ivhu rakaoma-musanganiswa dhaka rinoshandiswa zvakanyanya muindasitiri yekuvaka kune akasiyana maapplication, sekuzadza mapundu uye majoini, kugadzirisa makatsemuka mumadziro uye sirin'i, uye kugadzira ekushongedza moldings.Kuwedzera cellulose ethers kune gypsum mortar kunogona kuwedzera kushanda kwayo, kuchengetedza mvura, kuseta nguva uye simba.
1. Kuvandudza kushanda
Imwe yemabhenefiti makuru ekushandisa cellulose ethers mu gypsum mortar ndeyekuti inovandudza kushanda kwemusanganiswa.Kushanda (workability) zvinoreva nyore kusanganiswa, kutakurwa, nekuiswa pamusoro.Kushandisa cellulose ethers, gypsum mortar inowedzera mvura uye nyore kupararira, nokudaro kuderedza huwandu hwebasa rinodiwa pakusanganiswa nekushandiswa.Izvi zvinonyanya kukosha mumapurojekiti makuru ekuvaka uko nguva ndeye musimboti uye kumhanya kwekushandisa kunokanganisa kubereka.
2. Wedzera kuchengetwa kwemvura
Imwe mukana wekushandisa cellulose ethers mu gypsum mortar ndeyokuti inowedzera kuchengetwa kwemvura yemusanganiswa.Izvi zvakakosha nekuti gypsum mortar inowanzooma nekukurumidza, kunyanya munzvimbo yakaoma uye inopisa.Nokushandisa cellulose ethers, kuchengetwa kwemvura yemusanganiswa kunowedzera, zvinoreva kuti dhaka rinoramba rakanyorova kwenguva yakareba, zvichiita kuti zvive nyore kushanda uye kudzivirira kubva pakuputika kana kuputika nguva isati yakwana.Chimiro ichi chinobatsira munzvimbo dzine hunyoro hwakadzika kana panoda kuiswa dhaka panzvimbo yakatwasuka apo simba rinokwevera zvinhu pasi rinogona kuita kuti musanganiswa utsvedze.
3. Dzora nguva yekuvhara
Cellulose ether inowedzerwawo kune gypsum mortar kuti itonge nguva yayo yekugadzirisa.Kuisa nguva inguva inotora kuti mvura yegypsum mortar ishanduke kuita yakasimba.Iyi nhambo yenguva inokosha kugadziriro ipi neipi yokuvaka sezvo inosarudza kuti vashandi vanofanira kupedza basa kwenguva yakareba sei zvinhu zvisati zvaoma kushanda nazvo.Cellulose ethers inononotsa nguva yekumisikidzwa kwedhaka repurasita, zvichipa vashandi nguva yakawanda yekuisa nekuumba zvinhu zvisati zvaoma.
4. Wedzera simba
Kuwedzera cellulose ether kune gypsum mortar kunogonawo kuwedzera kusimba kwechigadzirwa chakapedzwa.Izvi zvinodaro nekuti cellulose ethers inoumba network mesh mukati megypsum mortar, zvichiita kuti isanyanya kutsemuka, kukotama kana kutyoka.Iyi ficha inobatsira mumapurojekiti ekuvaka uko chigadzirwa chakapedzwa chinoratidzwa kune yakakwira voltage mitoro, senge masisitimu epasi, zvimiro zvedenga kana madziro eindasitiri.
5. Kugarisana kwakanaka
Chimwe chinhu chakakosha che cellulose ethers mu gypsum mortars ndiko kuenderana kwayo kwakanaka nezvimwe zvikamu zvemusanganiswa.Cellulose ether ipolymer yechisikigo inofambirana nemamwe akawanda emakemikari ekuwedzera anowanzo shandiswa mumatope egypsum, senge retarders, superplasticizers uye air-entraining agents.Izvi zvinogonesa vavaki nevagadziri kugadzira tsika yegypsum mortar misanganiswa kuti isangane nezvinodiwa zvekuvaka.
mukupedzisa
Cellulose ether chinhu chinokosha chekuwedzera mu gypsum mortar, iyo inogona kuvandudza kushanda, kuchengetedza mvura, kuisa nguva, simba uye kuenderana kwegypsum mortar.Inoshandiswa zvakanyanya muindasitiri yekuvaka kugadzira zvigadzirwa zvemhando yepamusoro, zvinodhura uye zvinogara zvinosangana nezvinodiwa zvemapurojekiti ekuvaka emazuva ano.Nekushandisa cellulose ethers mune gypsum mortars, vavaki nevagadziri vanogona kuwedzera kugadzirwa, kushanda zvakanaka uye hupenyu hurefu hwezvigadzirwa zvavo zvakapedzwa, zvichiita kuti ive chikamu chakakosha chemaitiro ekuvaka emazuva ano.
