Cellulose ether mukongiri

Cellulose ether imhando yepolymer inonyungudika nemvura inoshandiswa mumhando dzakasiyana-siyana, kusanganisira kongiri.Iri pepa rinoongorora kushandiswa kwe cellulose ether mukrete uye nemigumisiro yayo pane zvinhu zvekrete.Pepa rinokurukura nezvemhando dze cellulose ethers dzinoshandiswa mukongiri, mhedzisiro yavo pane kongiri zvivakwa, uye zvakanakira nekuipira kwekushandisa cellulose ether mukongiri.Iro bepa zvakare rinoongorora tsvakiridzo iripo pakushandiswa kweselulosi ethers mukongiri uye inopa kurudziro yekutsvagisa ramangwana.

Nhanganyaya

Cellulose ethers imhando yepolymer inonyungudika mumvura yakashandiswa mumhando dzakasiyana dzekushandisa, kusanganisira kongiri.Cellulose ethers inoshandiswa kuvandudza kushanda, simba, uye kusimba kwekongiri.Izvo zvinoshandiswawo kuderedza kupera kwemvura, kunatsiridza kunamatira, uye kuderedza shrinkage.Cellulose ethers inowanzowedzerwa kune kongiri muchimiro chemusanganiswa wemvura kana hupfu.Iri pepa rinoongorora kushandiswa kwe cellulose ethers mukongiri uye mhedzisiro yayo pane zvinhu zvekongiri.

Mhando dzeCellulose Ethers

Cellulose ethers yakakamurwa kuita mapoka maviri makuru: hydroxyethylcellulose (HEC) uye hydroxypropylcellulose (HPC).HEC isiri-ionic cellulose ether inoshandiswa mukrete kuti ivandudze kushanda, kuderedza kupera kwemvura, uye kuderedza kuderera.HPC is an anionic cellulose ether inoshandiswa kuvandudza kunamatira uye kuderedza kupinza kwemvura.

Mhedzisiro paConcrete Properties

Kushandiswa kwe cellulose ethers mukrete kunogona kuva nemigumisiro inokosha pane zvinhu zvekrete.Cellulose ethers inogona kuvandudza kushanda kwekongiri nekuwedzera kuyerera kwekongiri musanganiswa.Izvi zvinogona kuderedza kuwanda kwemvura inodiwa kuti uwane kushanda kunodiwa.Cellulose ethers inogonawo kuderedza kupenya kwemvura uye shrinkage, izvo zvinogona kuvandudza kusimba kwekongiri.Mukuwedzera, cellulose ethers inogona kuvandudza kunamatira pakati pekongiri uye zvimwe zvinhu, sesimbi kana huni.

Zvakanakira uye Zvakaipa

Kushandiswa kwe cellulose ethers mukongiri kune zvakati wandei zvakanakira.Cellulose ethers inogona kuvandudza kushanda kwekongiri, kuderedza kupera kwemvura uye kuderera, uye kunatsiridza kunamatira.Pamusoro pezvo, cellulose ethers dzinenge dzisingadhure uye dziri nyore kushandisa.Nekudaro, pane zvimwe zvisingabatsiri kushandisa cellulose ether mukongiri.Cellulose ethers inogona kuderedza simba rekrete, uye inogonawo kuderedza mhepo yekrete, iyo inogona kuderedza kusimba kwekongiri.

Tsvakurudzo Yazvino

Pakave nehuwandu hunokosha hwekutsvakurudza kwakaitwa pamusoro pekushandiswa kwe cellulose ethers mukrete.Zvidzidzo zvakaratidza kuti cellulose ethers inogona kuvandudza kushanda uye kuderedza kupenya kwemvura uye kuderera kwekongiri.Mukuwedzera, zvidzidzo zvakaratidza kuti cellulose ethers inogona kuvandudza kunamatira kwekongiri kune zvimwe zvinhu.Nekudaro, pachine kudikanwa kweimwe tsvakiridzo kuti unzwisise zviri nani mhedzisiro ye cellulose ether pane zvinhu zvekongiri.

Mhedziso

Cellulose ethers imhando yepolymer inonyungudika nemvura inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira kongiri.Cellulose ethers inogona kuvandudza kushanda, kusimba, uye kusimba kwekongiri.Vanogonawo kuderedza kupera kwemvura uye kupera, uye kugadzirisa kunamatira.Pakave nehuwandu hunokosha hwekutsvakurudza kwakaitwa pamusoro pekushandiswa kweselulosi ethers mukongiri, asi pachine kudiwa kweimwe tsvakurudzo kuti unzwisise zviri nani zvinokonzerwa ne cellulose ethers pane zvinhu zvekongiri.
