Chimwe chezvinhu zvinonyanya kushandiswa mu dry-mix mortar ihydroxyethyl cellulose (HEC). HEC i non-ionic cellulose ether ine thickening, water retaining, stabilization, uye suspension properties. Inoshandiswa zvakanyanya mukuvaka, kunyanya mu dry-mix mortar.
1. Basa reHEC mudhaka rakaoma-rakasanganiswa
Mudhaka rakasanganiswa nedry-mix, HEC inonyanya kuita basa rekuchengetedza mvura, kukora uye kuvandudza mashandiro ekuvaka:
Kuchengeta mvura: HEC ine mukana wakanaka wekuchengetedza mvura uye inogona kuderedza kurasikirwa nemvura. Izvi zvakakosha zvikuru kune dhaka rakaoma nekuti rinoita kuti dhaka rirambe rakavhurika kwenguva yakareba, zvichibvumira vashandi kugadzirisa dhaka kwenguva yakareba uye kuvandudza mashandiro ekuvaka. Pamusoro pezvo, kuchengetedza mvura kunogonawo kuderedza njodzi yekutsemuka uye kuona kuti maitiro ekuomesa dhaka akafanana uye akagadzikana.
Kukora: Kukora kweHEC kunoita kuti dhaka rive nekusimba kwakanaka, zvichiita kuti dhaka rinyatsonamira pamusoro pe substrate panguva yekuvaka, zvisiri nyore kutsvedza, uye zvinovandudza kufanana kwekushandiswa. Hunhu uhwu hwakakosha zvikuru mukuvaka kwakamira uye hunogona kuvandudza zvikuru kunaka kwedhaka.
Kuvandudza mashandiro ekuvaka: HEC inogona kuita kuti dhaka rakasanganiswa nemvura rive nyore kushandisa, nokudaro zvichideredza kuoma kwekushanda. Inoita kuti dhaka rive nekupararira kwakanaka uye kunamira pachigadziko, zvichiita kuti kuvaka kuchengetedze vashandi uye kunatsiridza kushanda zvakanaka. Pamusoro pezvo, inogonawo kuwedzera kugona kwekudzivirira kudzika, kunyanya mukuvaka dhaka rakakora.
2. Maitiro ekusarudza HEC
Pakusarudza HEC, zvinhu zvakaita sehuremu hwayo, mwero wekutsiva uye kunyungudika kwayo zvinofanirwa kufungwa nezvazvo, izvo zvinozokanganisa zvakananga mashandiro edhaka:
Kurema kwemamorekuru: Hukuru hwehuremu hwemamorekuru hunokanganisa kugona kwekukora uye mhedzisiro yekuchengetedza mvura yeHEC. Kazhinji, HEC ine huremu hukuru hwemamorekuru ine mhedzisiro iri nani yekukora, asi mwero wekunyungudika unononoka; HEC ine huremu hudiki hwemamorekuru ine mwero wekunyungudika unokurumidza uye mhedzisiro yekunyungudika yakaipisisa zvishoma. Saka, zvakakosha kusarudza huremu hwakakodzera hwemamorekuru zvichienderana nezvinodiwa zvekuvaka.
Dhigirii rekutsiva: Dhigirii rekutsiva HEC rinoona kugadzikana kwayo uye kugadzikana kwayo. Dhigirii rekutsiva rakakwirira, kunyunguduka kweHEC kuri nani, asi kunyunguduka kunoderera; kana dhigirii rekutsiva rakaderera, kunyunguduka kwacho kwakakwira, asi kunyunguduka kwacho kunogona kunge kusina kunaka. Kazhinji, HEC ine mwero wekutsiva wakaringana ndiyo inonyanya kukodzera kushandiswa mumota yakasanganiswa yakaoma.
Kunyungudika: Mwero wekunyungudika kweHEC unokanganisa nguva yekugadzirira kuvaka. Kune dhaka rakasanganiswa rakaoma, zviri nani kusarudza HEC iri nyore kupararira nekunyungudika nekukurumidza kuti ivandudze kuchinjika kwekuvaka.
3. Kuchenjerera pakushandisa HEC
Paunenge uchishandisa HEC, unofanirwa kutarisisa huwandu hwayo hwekuwedzera uye mamiriro ekushandiswa kwayo kuti uve nechokwadi chekuti inoshanda zvakanaka:
Kudzora huwandu hwekuwedzera: Huwandu hwekuwedzera hweHEC hunowanzo dzorwa pakati pe0.1%-0.5% yehuremu hwese hwemota. Kuwedzera zvakanyanya kuchaita kuti mota ive yakakora zvakanyanya uye kukanganisa kuyerera kwekuvaka; kuwedzera kusina kukwana kunoderedza mhedzisiro yekuchengetedza mvura. Saka, bvunzo inofanira kuitwa zvichienderana nezvinodiwa chaizvo kuti uone huwandu hwakakodzera hwekuwedzera.
Kuenderana nezvimwe zvinowedzerwa: Mumortar yakasanganiswa yakaoma, HEC inowanzo shandiswa pamwe chete nezvimwe zvinowedzerwa zvakaita seupdha hwelatex hunonyungudika, cellulose ether, nezvimwewo. Nyatsoteerera kuenderana kweHEC nezvimwe zvinosanganisirwa kuti uve nechokwadi chekuti hapana kusawirirana uye kukanganisa mhedzisiro yacho.
Mamiriro ekuchengetedza: HEC inoyevedza, zvinokurudzirwa kuichengeta munzvimbo yakaoma uye kudzivirira zuva rakananga. Inofanira kushandiswa nekukurumidza mushure mekuvhurwa kudzivirira kudzikira kwekushanda kwayo.
4. Kushandiswa kweHEC
Mukushanda kwayo, HEC inogona kuvandudza mashandiro ekuvaka kwedhaka rakasanganiswa nemvura uye kuvandudza kunaka kwedhaka rose. Kukora uye kuchengetedza mvura kweHEC kunoita kuti dhaka rakasanganiswa nemvura rive rakanyatsonamira uye rakagadzikana, izvo zvisingangogadzirise kunaka kwekuvaka chete, asiwo zvinowedzera nguva yekuvhurwa kwedhaka, zvichibvumira vashandi kushanda vakanyarara. Pamusoro pezvo, HEC inogona kuderedza kuitika kwekutsemuka pamusoro pedhaka, zvichiita kuti dhaka rakaomeswa rigare kwenguva refu uye rive rakanaka.
5. Kudzivirirwa kwezvakatipoteredza uye hupfumi hweHEC
HEC chinhu chinobva mu cellulose chine hushamwari kune nharaunda chinoora uye hachikuvadzi nharaunda. Pamusoro pezvo, HEC ine mutengo wakaderera uye inodhura zvishoma, zvichiita kuti ive yakakodzera kushambadza nekushandisa mumhando dzakasiyana dzemapurojekiti ekuvaka. Kushandiswa kweHEC kunogona kuderedza huwandu hwemvura nesimende yedhaka, nokudaro kuchideredza kushandiswa kwemvura, izvo zvinoenderanawo nemaitiro aripo ekuchengetedza nharaunda yakasvibirira muindasitiri yekuvaka.
Kushandiswa kweHEC mudhaka rakasanganiswa nemvura kunogona kuvandudza mashandiro edhaka uye chinhu chinodiwa pakuvaka. Kuchengetedza mvura zvakanaka, kukora kwayo uye kugona kwayo kuchinjika pakuvaka kunovandudza kushanda zvakanaka kwedhaka uye kunoita kuti mhando igare yakasimba. Kusarudza
HEC yakakodzera uye kuishandisa nemazvo hakungogone kuvandudza kunaka kwekuvaka chete, asiwo kuzadzisa zvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye zvehupfumi.
