Mhedzisiro ye cellulose ether pahunhu hwe self-leveling mortar

Dura rinozvienzanisa rinogona kuvimba nehuremu hwaro kuti rigadzire hwaro hwakati sandara, hwakatsetseka uye hwakasimba pachigadziko chekuisa kana kubatanidza zvimwe zvinhu, uye panguva imwe chete rinogona kuita kuvaka kwakakura uye kwakanaka. Saka, kuyerera kwakanyanya chinhu chakakosha padura rinozvienzanisa. Pamusoro pezvo, rinofanira kunge riine simba rekuchengetedza mvura uye kubatanidza, risina kuparadzanisa mvura, uye rine hunhu hwekudziisa kupisa uye kukwira kwekupisa kwakaderera.

Kazhinji, dhaka rinozvienzanisa rinoda kuyerera kwakanaka, asi kuyerera kwedhaka resimende chaiyo kunowanzova 10-12cm chete; cellulose ether chinhu chikuru chinowedzera dhaka rakasanganiswa, kunyangwe huwandu hwekuwedzera huri hwakaderera, hunogona kuvandudza mashandiro edhaka zvakanyanya, hunogona kuvandudza kugadzikana, kushanda, mashandiro ekubatanidza uye mashandiro edhaka rekuchengetedza mvura.
 
1: Kuyerera kwedhaka
Cellulose ether ine simba guru pakuchengetwa kwemvura, kugara zvakanaka uye kushanda kwekuvaka kwemortar inozvienzanisa. Kunyanya semortar inozvienzanisa, kuyerera kwemvura ndeimwe yezviratidzo zvikuru zvekuongorora kushanda kwemortar inozvienzanisa. Pachishandiswa pfungwa yekuona kuti mortar yakaumbwa zvakanaka, kuyerera kwemortar kunogona kugadziriswa nekuchinja huwandu hwemortar inoenderana ne cellulose ether. Zvisinei, kana dosage yacho yakanyanya, kuyerera kwemortar kuchaderedzwa, saka dosage ye cellulose ether inofanira kudzorwa mukati mechikamu chakaringana.
 
2: Kuchengeta mvura mudhaka
Kuchengetwa kwemvura kwedhaka chiratidzo chakakosha chekuyera kugadzikana kwezvikamu zvemukati zvedhaka resimende rakasanganiswa. Kuti uite zvizere maitiro ekunyorovesa kwejeli, huwandu hwakaringana hwe cellulose ether hunogona kuchengetedza hunyoro mudhaka kwenguva yakareba. Kazhinji, mwero wekuchengetedza mvura wedhaka unowedzera nekuwedzera kwehuwandu hwe cellulose ether. Mhedzisiro yekuchengetedza mvura ye cellulose ether inogona kudzivirira substrate kuti isatore mvura yakawandisa nekukurumidza, uye kudzivirira kubuda kwemvura, kuitira kuti ive nechokwadi chekuti nharaunda yedhaka inopa mvura yakakwana ye hydration yesimende. Pamusoro pezvo, viscosity ye cellulose ether inewo simba guru pakuchengetedza mvura kwedhaka. Viscosity yakakwira, kuchengetedza mvura kuri nani. Kazhinji, cellulose ether ine viscosity ye400mpa.s inonyanya kushandiswa mudhaka rinozvienzanisa, izvo zvinogona kuvandudza mashandiro edhaka uye kuwedzera kusimba kwedhaka.
 
3: Nguva yekuisa dhaka
Cellulose ether ine simba rekudzora zvinhu pamortar. Nekuwedzera kwehuwandu hwe cellulose ether, nguva yekugadzika kwemortar inowedzera. Mhedzisiro yekudzora zvinhu pa cement paste inonyanya kutsamira padanho rekutsiva boka re alkyl, uye haina chekuita nehuremu hwayo hwemamorekuru. Dhigirii rekutsiva zvinhu paalkyl riri diki, huwandu hwehydroxyl huri kukura, uye mhedzisiro yekudzora zvinhu paalkyl iri pachena. Uye huwandu hwe cellulose ether huri pamusoro, mhedzisiro yekunonoka kwefirimu yemusanganiswa pamvura yekutanga yesimende iri pachena, saka mhedzisiro yekudzora zvinhu paalkyl iri pachenawo.
 
4: Simba rekudzvanya remortar uye simba rekugonya
Kazhinji, simba ndiro rimwe remaindekisi akakosha ekuongorora mashandiro ekugadzira simende yakagadzirwa nesimende pamusanganiswa. Kana huwandu hwe cellulose ether hukawedzera, simba rekudzvanya uye simba rekutenderera kwesimbi yesimbi zvinodzikira.
 
5: Simba rekubatanidza dhaka
Cellulose ether ine simba guru pakushanda kwesimbi. Cellulose ether inogadzira firimu repolymer rine simba rekuvhara pakati pesimbi yesimbi muchikamu chemvura, izvo zvinoita kuti mvura yakawanda mufirimu repolymer ibude kunze kwesimbi yesimbi, izvo zvinoita kuti simende iwane mvura yakakwana, nokudaro zvichivandudza simba resimbi mushure mekuoma. Panguva imwe chete, huwandu hwakakodzera hwesimbi yesimbi yesimbi inowedzera plasticity uye kuchinjika kwesimbi, inoderedza kuomarara kwenzvimbo yekuchinja pakati pesimbi nesubstrate interface, uye inoderedza kugona kutsvedza pakati pesimbi. Kusvika pamwero wakati, simba resimbi ye ...
