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 10-300px chete; cellulose ether chinhu chikuru chinowedzera dhaka rakasanganiswa, kunyangwe huwandu hwekuwedzera huri hwakaderera, hunogona kuvandudza mashandiro edhaka, hunogona kuvandudza kugadzikana, kushanda, mashandiro ekubatanidza uye mashandiro edhaka rekuchengetedza mvura. Rinoita basa rakakosha mumunda wedhaka rakasanganiswa.
1. Kuyerera: 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. Pasi pepfungwa yekuona kuti mortar yakaumbwa zvakanaka, kuyerera kwemortar kunogona kugadziriswa nekuchinja huwandu hwe cellulose ether. Zvisinei, kana huwandu hwacho hwakanyanya, kuyerera kwemortar kuchaderedzwa, saka huwandu hwe cellulose ether HPMC hunofanira kudzorwa mukati mehuwandu hwakakodzera.
2. Kuchengetwa kwemvura: Kuchengetwa kwemvura mudura chiratidzo chakakosha chekuyera kugadzikana kwezvikamu zvemukati zvedura resimende rakasanganiswa. Kuti uite zvizere maitiro ekunyorovesa kwejeli, huwandu hwakaringana hwe cellulose ether hunogona kuchengetedza hunyoro mudura kwenguva yakareba. Kazhinji, mwero wekuchengetedza mvura mudura unowedzera nekuwedzera kwehuwandu hwe cellulose ether. Mhedzisiro yekuchengetedza mvura ye cellulose ether HPMC inogona kudzivirira substrate kuti isatore mvura yakawandisa nekukurumidza, uye kudzivirira kubuda kwemvura, kuitira kuti ive nechokwadi chekuti slurry environment inopa mvura yakakwana ye hydration yesimende. Pamusoro pezvo, viscosity ye cellulose ether inewo simba guru pakuchengetedza mvura mudura. Viscosity yakakwira, kuchengetedza mvura kuri nani. Kazhinji, cellulose ether HPMC ine viscosity ye400mpa.s inonyanya kushandiswa mudura rinozvienzanisa, izvo zvinogona kuvandudza mashandiro edura uye kuwedzera kusimba kwedura.
3. Nguva yekuisa: Cellulose ether ine simba rekudzora pamortar. Nekuwedzera kwehuwandu hwe cellulose ether, nguva yekuisa mortar inowedzera. Mhedzisiro yekudzora ye cellulose ether HPMC pa cement paste inonyanya kutsamira padanho rekutsiva boka re alkyl, uye haina hukama hwakawanda nehuremu hwayo hwemamorekuru. Dhigirii rekutsiva alkyl riri diki, huwandu hwe hydroxyl huri kukura, uye mhedzisiro yekudzora iri pachena. Uye huwandu hwe cellulose ether hwakakwira, mhedzisiro yekunonoka ye complex film layer iri pachena pakunyorovesa simende kwekutanga, saka mhedzisiro yekudzora iri pachenawo.
4. Simba rekuchinjika uye simba rekudzvanya: Kazhinji, simba ndicho chimwe chezviratidzo zvakakosha zvekuongorora mashandiro ekugadzira simende yakagadzirwa nesimende pamusanganiswa. Simba rekudzvanya uye simba rekuchinjika resimbi yedhaka rinodzikira nekuwedzera kwehuwandu hwe HPMC mu cellulose ether.
5. Simba rekubatanidza: cellulose ether HPMC ine simba guru pakushanda kwesimbi. Cellulose ether inoumba firimu repolymer rine simba rekuvhara pakati pesimbi yesimbi muchikamu chemvura, izvo zvinosimudzira mvura yakawanda mufirimu repolymer kunze kwesimbi yesimbi, izvo zvinoita kuti simende iwane mvura yakakwana, nokudaro zvichivandudza simba resimbi mushure mekuoma. Panguva imwe chete, huwandu hwakakodzera hwesimbi yesimbi yesimbi hunosimbisa purasitiki nekuchinjika kwesimbi, hunoderedza kuomarara kwenzvimbo yekuchinja pakati pesimbi nesubstrate interface, uye hunoderedza kugona kutsvedza pakati pesimbi. Kusvika pamwero wakati, simba resimbi ye ...
