Kufurira Zvinhu zveCellulose Ether pane Cement Mortar

Cellulose ethers inoita basa rakakosha mukupesvedzera zvimiro zvesamende dhaka, zvichikanganisa kushanda kwayo, kunamatira, kuchengetedza mvura, uye simba remuchina. Zvinhu zvakati wandei zvinogona kukanganisa kuita kwe cellulose ethers mudhaka simende:

1. Kemikari Inoumbwa: Iyo kemikari inoumbwa ye cellulose ethers, kusanganisira iyo dhigirii yekutsiva (DS) uye mhando yeanoshanda mapoka (eg, methyl, ethyl, hydroxypropyl), anokanganisa zvakanyanya maitiro avo mune simende dhaka. Yepamusoro DS uye mamwe marudzi emapoka anoshanda anogona kusimudzira kuchengetedza kwemvura, kunamatira, uye kukora zvivakwa.
2. Particle Kukura uye Kugovera: Iyo particle size uye kugoverwa kwe cellulose ethers inogona kukanganisa kupararira kwavo uye kupindirana nezvikamu zvesimende. Zvikamu zvakanaka zvine yunifomu yekugovera zvinowanzopararira zvakanyanya mumatope matrix, zvichiita kuti kuve nani kuchengetwa kwemvura uye kushanda.
3. Chiyero: Chiyero che cellulose ethers mune sement mortar formulations chinokanganisa kushanda kwavo. Optimal dosage mazinga anotemerwa zvichienderana nezvinhu zvakaita sezvinodiwa kushanda, zvinodiwa kuchengetedza mvura, uye simba remuchina. Kuwedzeresa dosage kunogona kukonzera kukora zvakanyanya kana kunonoka kwekugadzika nguva.
4. Kusanganisa Maitiro: Maitiro ekusanganisa, anosanganisira nguva yekusanganisa, kukurumidza kusanganisa, uye kurongeka kwekuwedzera kwezvinwiwa, zvinogona kukanganisa kupararira uye hydration ye cellulose ether musamende samende. Kusanganiswa kwakakodzera kunovimbisa kugovera kwakafanana kweselulosi ether mukati medhaka matrix, kunowedzera kushanda kwavo mukuvandudza kushanda uye kunamatira.
5. Simende Maumbirwo: Rudzi uye kuumbwa kwesimende inoshandiswa mukuumbwa kwedhaka kunogona kukanganisa kuenderana uye kushanda kwe cellulose ethers. Mhando dzakasiyana dzesimende (semuenzaniso, simende yePortland, simende yakasanganiswa) inogona kuratidza kudyidzana kwakasiyana-siyana nema cellulose ethers, zvichikanganisa zvivakwa zvakaita sekuseta nguva, kusimukira kwesimba, uye kusimba.
6. Aggregate Properties: Izvo zvimiro zveaggregates (semuenzaniso, particle size, shape, surface texture) zvinogona kukanganisa kushanda kwe cellulose ethers mudhaka. Aggregates ane hutsinye kana maumbirwo asina kujairika anogona kupa zvirinani mechanic interlock ne cellulose ethers, inosimudzira adhesion uye kubatana mudhaka.
7. Mamiriro Ezvakatipoteredza: Zvinhu zvakatipoteredza zvakadai sekushisa, humidity, uye kuporesa mamiriro ezvinhu zvinogona kukanganisa hydration uye kushanda kwe cellulose ethers mumatope esimende. Kunyanya tembiricha kana humidity mazinga anogona kushandura nguva yekuseta, kushanda, uye michina yedhaka ine cellulose ethers.
8. Kuwedzerwa kweZvimwe Zvinowedzerwa: Kuvapo kwezvimwe zvinowedzera, zvakadai se superplasticizers, air-entraining agents, kana seti yekusimudzira, inogona kuwirirana ne cellulose ethers uye inokonzera kushanda kwavo mumatope esimende. Kuyedzwa kwekuenderana kunofanirwa kuitwa kuongorora synergistic kana antagonistic mhedzisiro yekubatanidza cellulose ether nezvimwe zvinowedzera.

Kunzwisisa zvinofurira zvinhu zve cellulose ethers padhaka resimende kwakakosha pakugadzirisa maumbirwo edhaka uye kuwana zvinhu zvinodiwa sekuvandudza kushanda, kuchengetwa kwemvura, uye simba remuchina. Kuita ongororo dzakadzama uye zviedzo zvinogona kubatsira kuona akanyatsokodzera cellulose ether zvigadzirwa uye mazinga edosi kune chaiwo madhaka ekushandisa.
