Cellulose ethers zvinhu zvakakosha zvinoshandiswa mukuvaka, kunyanya mukugadzirwa kwemateki akanyorova kune akasiyana maapplication akadai sepasi, denga uye plastering. Chinangwa chikuru che cellulose ether mudhaka rakanyorova ndechekusimudzira kushanda kwayo nekuwedzera viscosity yayo. Wet mortar chigadziko chinogadzirwa chinoshandiswa kubatanidza nekusimbisa zvinhu zvekuvaka zvakasiyana. Mumapurojekiti ekuvaka, kushandiswa kwakakodzera kunokosha pakubudirira uye hupenyu hurefu hwechimiro. Naizvozvo, kushandiswa kwema cellulose ethers mumadhaka akanyorova kwakakosha kuwedzera viscosity ye optimum consistency uye kuita.
Imwe yemabhenefiti akakosha ekushandisa cellulose ether mumatope emvura ndeyekuwedzera viscosity. Viscosity of wet mortar zvinoreva kugona kwemusanganiswa kuyerera zvakanaka uye zvakaenzanirana. Cellulose ether inonyatsokodzera chinangwa ichi sezvo inoumba colloidal solution kana yawedzerwa kumvura, inosimudzira hydrophilicity uye adhesion. Nekuda kweizvozvo, iyo dhaka yakanyorova inova yakasimba uye yakawanda viscous, iyo inobvumira kuenderana kuri nani kwezvinangwa zvekuvaka.
Cellulose ether inzvimbo yakakwana yekuchengetedza mvura inovandudza kushanda kwematope emvura. Kana yakasanganiswa ne cellulose ether, dhaka rakanyorova rinoratidzawo zvakanakisa kuchengetedza mvura, kudzivirira mamorekuru emvura kubva pakubuda kwemaawa kana mazuva, achiwedzera nguva yekumisikidza yedhaka. Izvi zvinovandudza kushanda kwemusanganiswa, zvichipa vashandi nguva yakawanda yekushanda uye kupedza mabasa dhaka rakanyorova risati ramira.
Imwe mukana wakakosha wekushandisa cellulose ether mudhaka rakanyorova ndiko kubatanidzwa kwakavandudzika kwedhaka. Zvinonyatsozivikanwa kuti kunaka kwevhu rekuvaka dhaka kunobata zvakanyanya hupenyu hwebasa uye kusimba kwechimiro. Iyo dhaka yakanyorova ine cellulose ether haigone kungobatana nekukurumidza nezvimwe zvinhu zvekuvaka, asiwo kusungirira kwakasimba uye kwenguva refu. Naizvozvo, kuunzwa kwe cellulose ether mudhaka rakanyorova kunogona kuwedzera kubatana kwayo uye kupa mukana uri nani wekubudirira kweprojekiti.
Pamusoro pezvakanakira zvambotaurwa, cellulose ethers inogona zvakare kunatsiridza kusimba kwechisungo chedhaka rakanyorova. Kana ichishandiswa mudhaka rakanyorova, cellulose ethers inosimudzira kugona kwekunamira kwedhaka, ichibvumira kuti ibatane zvakasimba nezvimwe zvekuvaka, zvinosanganisira kongiri, zvidhinha nedombo. Izvi zvinowedzera kusimba uye kushanda kwenguva refu kwechimiro, sezvo zvisungo zvakasimba zvinobatsira kuderedza dambudziko rekukuvara kwemaitiro uye kuparara.
Kushandiswa kwema cellulose ethers mumadhaka akanyorova ndiyo mhinduro yakanaka kune akawanda ematambudziko anotarisana nenyanzvi dzekuvaka mumabasa avo ezuva nezuva. Nekuwedzera viscosity, kushanda, kubatana uye kusimba kwechisungo chematope emvura, cellulose ethers inovimbisa kuti chimiro chekupedzisira chakasimba, chinogara kwenguva refu uye chinokwanisa kutsungirira mamiriro ekunze akaoma. Naizvozvo, senyanzvi yekuvaka yemazuva ano, kushandiswa kwema cellulose ether mudhaka rakanyorova kwakakosha pakubudirira kwezvirongwa zvekuvaka.
Kushandiswa kwe cellulose ethers mumatope emvura chinhu chakakosha pakuvandudza kuwirirana, kusimba uye kushanda kwemusanganiswa. Izvo zvakanakisa zvimiro zvedhaka rakanyorova, senge yakagadziridzwa viscosity, kushanda, kubatana uye kusimba kwechisungo, inoita kuti ive inonamira yakanakira yeakasiyana mafomu ekuvaka. Naizvozvo, nyanzvi dzekuvaka dzinofanirwa kumbundira hunyanzvi hwekuvaka hwemazuva ano uye kuchinjika zvinoenderana kuti vave nechokwadi chekuti vanoshandisa zvinhu zvakanakisa mumapurojekiti avo. Kuvaka varidzi veprojekiti uye vanoisa mari vanogona kuwana mhedzisiro iri nani, zvivakwa zvakasimba uye kusimba kwenguva refu nekushandisa cellulose ethers mumadhaka akanyorova.
