Dry mortar chinhu chekuvaka chinosanganisira jecha, simende uye zvimwe zvinowedzera. Inoshandiswa kubatanidza zvidhinha, zvidhinha uye zvimwe zvinhu zvekuvaka kugadzira zvivakwa. Zvisinei, dhaka rakaoma haisi nyore nguva dzose kushanda naro sezvo rinowanzorasikirwa nemvura uye rinova rakaoma zvikuru nokukurumidza. Cellulose ethers, kunyanya hydroxypropylmethylcellulose (HPMC) uye methylhydroxyethylcellulose (MHEC), dzimwe nguva inowedzerwa kune yakaoma dhaka kuti ivandudze maitiro ayo ekuchengetedza mvura. Chinangwa chechinyorwa chino ndechekuongorora mabhenefiti ekushandisa cellulose ether mudhaka rakaoma uye kuti ingavandudza sei kunaka kwekuvaka.
Kuchengeta mvura:
Kuchengetwa kwemvura kunoita basa rinokosha muhutano hwedhaka rakaoma. Kuchengetedza hunyoro hwakakodzera hunodiwa kuti uve nechokwadi chekuti dhaka rinogadzika zvakakwana uye rinogadzira chisungo chakasimba pakati pezvinhu zvekuvaka. Zvisinei, dhaka rakaoma rinorasa mwando nekukasira, kunyanya munzvimbo dzinopisa, dzakaoma, izvo zvinoita kuti pave nedhaka rakashata. Kugadzirisa dambudziko iri, cellulose ethers dzimwe nguva inowedzerwa kune yakaoma dhaka kuti ivandudze maitiro ayo ekuchengetedza mvura.
Cellulose ethers mapolymers anotorwa kubva ku cellulose, iyo yakasikwa fiber inowanikwa muzvirimwa. HPMC neMHEC marudzi maviri e-cellulose ethers anowanzowedzerwa kune yakaoma madhaka kuvandudza kuchengetwa kwemvura. Vanoshanda kuburikidza nekugadzira gel-sechinhu chakasanganiswa nemvura, iyo inobatsira kuderedza kuoma kwedhaka.
Zvakanakira kushandisa cellulose ether mudhaka rakaoma:
Pane mabhenefiti akati wandei ekushandisa cellulose ether mudhaka rakaoma, kusanganisira:
1. Kuvandudza kushanda: Cellulose ether inogona kuvandudza kushanda kwevhu rakaoma nekuderedza kuoma kwayo uye kuwedzera plastiki yayo. Izvi zvinoita kuti zvive nyore kuisa dhaka kune chivakwa chekuvakisa kuti iwedzere kunakidza kupera.
2. Kutsemuka kwakaderedzwa: Dhaka rakaoma rinogona kutsemuka kana ranyanya kuoma, zvichikanganisa simba rayo. Nekuwedzera cellulose ether kumusanganiswa, dhaka rinooma zvishoma nezvishoma, kuderedza njodzi yekutsemuka uye kuwedzera simba rayo.
3. Kuwedzerwa simba rezvisungo: Kusungirirwa kwedhaka rakaoma kune zvigadzirwa zvekuvaka zvakakosha pakuita kwayo. Cellulose ethers inowedzera kuchengetwa kwemvura yedhaka, iyo inowedzera simba rayo rezvisungo, zvichiita kuti pave nechisungo chakasimba, chinogara kwenguva refu.
4. Kuvandudza kusimba: Cellulose ether inogona kuvandudza kusimba kwedhaka rakaoma nekuderedza kuwanda kwemvura yakarasika panguva yekuoma. Nekuchengeta mvura yakawanda, dhaka harisi nyore kutsemuka kana kuputsika, zvichiita kuti chimiro chigare chakasimba.
Dry mortar chinhu chakakosha pakuvaka. Zvakadaro, zvimiro zvayo zvekuchengetedza mvura zvinogona kunetsa kubata, zvichikonzera dhaka rakashata. Kuwedzera cellulose ethers, kunyanya HPMC neMHEC, kuoma dhaka kunogona kuvandudza zvakanyanya kushanda kwayo kwekuchengetedza mvura, zvichikonzera chigadzirwa chepamusoro. Mabhenefiti ekushandisa cellulose ethers mumatope akaoma anosanganisira kuvandudzwa kwekushanda, kuderedzwa kutsemuka, kusimba kwechisungo uye kuwedzera kusimba. Nekushandisa cellulose ether mudhaka rakaoma, vavaki vanogona kuona kuti zvivakwa zvavo zvakasimba, zvinogara uye zvinoyevedza.
