Madhaka emhando yepamusoro anozvitsigira nehuremu hwawo kuti agadzire hwaro hwakati sandara, hwakatsetseka uye hwakasimba pachigadziko, zvichibvumira zvimwe zvinhu kuti zvibatanidzwe kana kusungirirwa, ukuwo zvichiita nzvimbo huru uye dzinoshanda dzekuvaka. Nokudaro, kuyerera kwakanyanya hunhu hwakakosha hwedhaka remhando yepamusoro rinozvienzanisa. Rinofanirawo kuva nemwero wakati wekuchengetedza mvura nesimba rekubatanidza, risina kupwanyika uye kupatsanurwa, uye rive rakadzikama uye tembiricha yakaderera.
Dhoka rinozvienzanisa rinoda kuyerera kwakanaka, asi kuyerera kwejecha resimende kunowanzova 10-12cm chete; cellulose ether ndiyo inonyanya kushandiswa mudhoka rakasanganiswa, kunyangwe huwandu hwakawedzerwa hwakaderera, hunogona kuvandudza mashandiro edhoka, izvo zvinogona kuvandudza kugadzikana kwedhoka, kushanda zvakanaka, kushanda kwekubatanidza uye mashandiro ekuchengetedza mvura. Rine basa rakakosha mumunda wedhoka rakasanganiswa.
1 Kuyerera
Cellulose ether ine simba guru pakuchengetwa kwemvura, kugara zvakanaka uye kushanda zvakanaka kwemortar. Kunyanya semortar inozvienzanisa, kuyerera kwemvura ndeimwe yezviratidzo zvikuru zvekuongorora mashandiro emortar. Kuyerera kwemortar kunogona kugadziriswa nekuchinja huwandu hwemortar cellulose ether pasi pechinangwa chekuona kuti mortar yakagadzirwa zvakanaka. Kuwanda kwemvura kunoderedza kuyerera kwemortar, saka, huwandu hwemortar cellulose ether hunofanira kudzorwa mukati mehuwandu hwakakodzera.
2 Kuchengetwa kwemvura
Dura rinochengetedza mvura chiratidzo chakakosha chekugadzikana kwezvikamu zvemukati zvedura resimende. Kuti gel iite kuti mvura irambe yakakwana, huwandu hwakaringana hwe cellulose ether hunogona kushandiswa kwenguva yakareba kuchengetedza mvura mudura. Kazhinji, sezvo huwandu hwe cellulose ether huchiwedzera, kuchengetwa kwemvura kwedura kunowedzerawo. Pamusoro pezvo, kutaridzika kwe cellulose ether kune mhedzisiro yakakura pakuchengetwa kwemvura kwedura; kutaridzika kwakanyanya, kuchengetwa kwemvura kuri nani.
3 Nguva yekuisa
Cellulose ether ine simba rekudzivirira simbi. Nekuwedzera kwehuwandu hwe cellulose ether, nguva yekugadzika simbi inowedzerwa. Uye nehuwandu hwakawanda hwe cellulose ether, mhedzisiro yekutanga ye hydration hysteresis yesimende inoonekwa zviri pachena.
4 Simba rekuchinjika uye simba rekudzvanya
Kazhinji, simba ndeimwe yenzira dzakakosha dzekuongorora musanganiswa wesimbi inosimbisa simende. Simba rekudzvanya uye simba rekuchinjika kwesimbi inosimbisa simende zvichadzikira kana huwandu hwe cellulose ether hukawedzera.
