Kukwirira uye kugadzikana kwekuvakwa kwakagadzirwa kwedhaka rekupurasita ndizvo zvinhu zvakakosha zvekusimudzira, uye cellulose ether, sechinhu chikuru chekuwedzera chekupura dhaka, inoita basa risingadzokerike.Cellulose etherine hunhu hwepamusoro pekuchengetedza mvura mwero uye yakanaka kuputira pfuma, uye inonyanya kukodzera mechanizedkuvakayedhaka rekupurasita.
Mwero wekuchengetedza mvura yedhaka rekupurasita
Mwero wekuchengetedza mvura yekupurasita dhaka iri kuwedzera maitiro apo viscosity ye cellulose ether ichibva pa50,000 kusvika 100,000, uye iri kuderera maitiro kana iri kubva pa100,000 kusvika 200,000, nepo mwero wekuchengetedza mvura we cellulose ether yekupfapfaidza muchina wasvika. zvinopfuura 93%.Kukwira kwehuwandu hwekuchengetedza mvura kwedhaka, kashoma kuti dhaka ribude ropa.Munguva yekuedza kupfapfaidza nemuchina wekupfapfaidza dhaka, zvakaonekwa kuti kana mwero wekuchengetedza mvura we cellulose ether wakaderera pane 92%, dhaka rinowanzobuda ropa mushure mekuiswa kwenguva yakati, uye, pakutanga kwekupfapfaidza. , inonyanya nyore kuvhara pombi.Naizvozvo, kana tichigadzira dhaka rekupurasita yakakodzera kugadzirwa nemichina, tinofanira kusarudza cellulose ether ine yakakwirirakuchengetedza mvurarate.
Plastering dhaka 2h kusawirirana kurasikirwa
Zvinoenderana nezvinodiwa zveGB/T25181-2010 "Ready Mixed Mortar", iyo maawa maviri yekusagadzikana kurasikirwa kunodiwa kweyakajairwa plastering dhaka isingasviki makumi matatu%.Iyo 2h kusawirirana kurasikirwa kuedza kwakaitwa nemaviscosities e50,000, 100,000, 150,000, uye 200,000.Zvinogona kuonekwa kuti sezvo viscosity ye cellulose ether inowedzera, iyo 2h kusawirirana kurasikirwa kukosha kwedhaka kuchaderera zvishoma nezvishoma.Zvisinei, panguva chaiyo yokupfapfaidza, zvakaonekwa kuti panguva gare gare leveling kurapwa, nokuti viscosity cellulose eteri yakanyanyisa, kubatana pakati dhaka uye trowel achava mukuru, izvo zvisingabatsiri kuvaka.Nokudaro, munyaya yekuona kuti dhaka harigadziki uye harina delaminate, iyo yakaderera iyo viscosity kukosha kwe cellulose ether, zviri nani.
Kupura dhaka kuvhuranguva
Mushure meplastering dopeinopfapfaidzwa pamadziro, nekuda kwekutorwa kwemvura kwemadziro substrate uye kubuda kwehunyoro pamusoro pevhu, dhaka richaumba rimwe simba munguva pfupi, izvo zvinokanganisa kunotevera kuvakwa kwemazinga, saka ndizvo. zvakakosha kuongorora nguva yekugadzika kwedhaka.Iko viscosity value ye cellulose ether iri muhuwandu hwe100,000 kusvika ku200,000, nguva yekuisa haishanduki zvakanyanya, uye inewo imwe hukama nehuwandu hwekuchengetedza mvura, kureva, iyo yakakwirira yemvura yekuchengetedza mvura, iyo yakareba. nguva yakatarwa yedhaka.
Fluidity yekupurasita dhaka
Kurasikirwa kwemidziyo yekupfapfaidza kune zvakawanda zvekuita nekuyerera kwedhaka rekupurasita.Pasi pechiyero chimwe chemvura-yezvinhu, iyo yakakwira viscosity ye cellulose ether, inodzika iyo fluidity kukosha kwedhaka.Izvi zvinoreva kuti, iyo yakakwira viscosity ye cellulose ether, iyo yakakura kushorwa kwedhaka uye yakakura kupfeka uye kubvarura pamidziyo.Nokudaro, nokuda kwekugadzirwa kwemakanika kwekugadzira dhaka, iyo yakaderera viscosity ye cellulose ether iri nani.
Sag resistance ye plastering mortar
Mushure mekupura dhaka yakapfapfaidzwa pamadziro, kana iyo sag resistance yedhakahazvina kunaka, dhaka rinodonha kana kutotsvedza, zvichikanganisa kudzika kwedhaka, izvo zvinokonzeresa dambudziko guru pakuvaka kunotevera.Naizvozvo, dhaka rakanaka rinofanira kunge riine yakanakisa thixotropy uye sag kuramba.Kuedza kwakaona kuti mushure meiyo cellulose ether ine viscosity ye50,000 uye 100,000 yakamiswa yakatwasuka, matiles akatsvedza pasi, nepo cellulose ether ine viscosity ye150,000 uye 200,000 haina kutsvedza.Iyo kona ichiri yakatwasuka, uye hapana kutsvedza kuchaitika.
Simba rekupurasita dhaka
Tichishandisa 50 000, 100 000, 150 000, 200 000, uye 250 000 cellulose ether kugadzira masample edhaka rekupurasita nokuda kwekuvaka nemichina, zvakaonekwa kuti nekuwedzera kwe cellulose ether viscosity, kukosha kwesimba kwekupurasita dhaka kuderera.Izvi ndezvokuti cellulose ether inoumba mhinduro yepamusoro-viscosity mumvura, uye nhamba yakawanda yemhepo yakagadzikana inoputika ichaunzwa panguva yekusanganiswa kwedhaka.Mushure mekunge simenti yaoma, aya mabhubhu emhepo anoumba nhamba huru yevoids, nokudaro kuderedza kukosha kwesimba kwedhaka.Naizvozvo, dhaka rekupurasita rakakodzera kuvakwa kwemichina rinofanira kukwanisa kuzadzisa kukosha kwesimba kunodiwa nedhizaini, uye yakakodzera cellulose ether inofanirwa kusarudzwa.
Iko kurongeka kwemunhu-muchina zvinhu ndicho chinhu chakakosha pakuvaka mechan, uye mhando yedhaka ndiyo inonyanya kukosha.Chete nekushandisa iyo yakakodzera cellulose ether inogona kuita zvimiro zvedhaka kusangana nezvinodiwa zvemushini wekupfapfaidza.
