Cellulose ethers inowanzoshandiswa sezvinowedzera mu gypsum-based mortars kuwedzera zvivakwa zvakasiyana uye maitiro ekuita.Izvi zvinotevera mamwe mashandisirwo e cellulose ethers mu gypsum mortar:
Kuchengeta mvura:
Cellulose ethers ma hydrophilic polymers, zvichireva kuti vane hukama hwepamusoro hwemvura.Kana yawedzerwa kudhaka rekupurasita, inonyatso kuchengetedza unyoro uye inodzivirira musanganiswa kubva pakuoma nekukasira.Izvi zvakakosha kuti uve nechokwadi chekuti plaster ine nguva yakakwana yekunyorova nemazvo uye kugadzirisa kushanda.
Processability uye nyore kushandisa:
Iyo yekuchengeta mvura zvinhu zve cellulose ethers inobatsira kuvandudza kushanda kwegypsum mortar.Doka rinova nyore kusanganisa, kuparadzira uye kushandisa, zvichiita kuti maitiro ekuvaka ave akapfava uye anoshanda zvakanyanya.
Deredza shrinkage:
Cellulose ethers inobatsira kudzora kuoma kwe gypsum mortars.Nekuchengetedza mvura yakakwana panguva yekumisikidza uye kuomesa, cellulose ethers inobatsira kuderedza shrinkage kuparuka uye kuve nechokwadi chekugadzikana kwedimensional yechigadzirwa chakapedzwa.
Natsiridza adhesion:
Cellulose ethers inosimudzira kunamatira kwegypsum mortar kune akasiyana substrates, kusanganisira madziro uye sirin'i.Izvi zvinonyanya kukosha mumashandisirwo akadai sekupurasita uye kupa, uko chisungo chakasimba chakakosha pakugara uye hupenyu hurefu hwepasi rakapedzwa.
Crack resistance:
Kuwedzera cellulose ether kunogona kuvandudza kutsemuka kwedhaka.Izvi zvinonyanya kubatsira munzvimbo umo kufamba kwemaitiro kunowanzoitika kana uko dhaka rinogona kusimbiswa, senge majoini emubatanidzwa uye putty layers.
Anti-sag:
Mumashandisirwo akatwasuka, akadai semadziro plasters, cellulose ethers anoita seanokora, kuderedza sag uye kudonha kwedhaka.Ichi chimiro chinobatsira kuchengetedza yunifomu ukobvu panzvimbo yakatwasuka, kuvandudza aesthetics uye kuita kwekupedzisira application.
Wedzera kubatana:
Cellulose ethers inobatsira pakubatana kwemusanganiswa wedhaka, kuvandudza hutano hwayo hwose.Izvi zvakakosha mumashandisirwo apo dhaka rinoda kumirisana nemasimba ekunze kana kushushikana.
Kugadzikana kwechando-nyoro:
Cellulose ethers inogona kuwedzera kugadzika kwechando-kunyorova kwegypsum mortars, zvichiita kuti isanyanya kukuvadzwa munzvimbo dzine tembiricha dzinochinja.Izvi zvinonyanya kukosha kune zvikumbiro zvekuvaka zvakaratidzwa kune mamiriro ekunze akaoma.
Wedzera nguva yekuisa:
Kushandisa cellulose ethers kunogona kuwedzera nguva yekuseta yedhaka, zvichibvumira kuchinjika kukuru mukushandisa nekupedzisa.Izvi zvinonyanya kukosha mumamiriro ezvinhu apo maawa akawanda ekushanda anodiwa.
Kuvandudza rheological properties:
Cellulose ethers inobatsira kune rheological properties yedhaka, ichikonzera kuyerera kwayo uye deformation maitiro.Izvi zvinobatsira kuwana kuenderana kunodiwa uye kuita kwekushandisa.
Zvakakosha kucherechedza kuti iyo chaiyo mhando uye chiyero che cellulose ether yakashandiswa uye kugadzirwa kwegypsum mortar kunofanirwa kunyatsotariswa kuti uwane mhedzisiro inodiwa mune yakapihwa application.Vagadziri vanowanzoita kuyedza uye optimization kuti vaone yakanyanya kunaka cellulose ether zvemukati kune avo chaiwo zvigadzirwa uye mashandisiro anodiwa.
