Cellulose ether inzvimbo yakakosha yekuvaka yekuvaka iyo inowanzoshandiswa zvakanyanya mukongiri uye mongwe kuvandudza zvivakwa zvavo. Mashandiro makuru e cellulose ether mu concrete inosanganisira kuronga kwemvura, kunonoka kurongedza, kuvandudza basa, nezvimwe.
1. Methyl Cellulose (MC, methyl cellulose)
Methylcellose ndiyo inonyanya kukosha mhando ye cellulose ether, iyo inogadzirwa nekutsiva mamwe mapoka ehydroxyl mu cellulose ine mapoka mapoka (-Och3). Methylcellose inonyanya kuita basa rekuremedza uye nekuchengetwa kwemvura muongiri. Zvinogona kuvandudza zvakanyanya kuparara kongiri, wedzera kubatana kwekongiri, kuderedza kubuda ropa, nekukasira kugadzirisa basa rekuvaka uye kusimba kwekongiri. Mukuwedzera, methylcellose ine zvakare yakanaka firimu-inoumba zvivakwa, izvo zvinogona kubatsira zvinobudirira kusimba uye kufanana kwekongiri yemakonzo.
2. Hydroxyprusyl methyl cellelose (HPMC, hydroxypropyl methyl cellelose)
HydroxyPropyl methylcellose inogadzirwa nekuenderera mberi kuisazve hydroxypropropropropropropyl (-ch2chohch3) pahwaro hwe methylceulose. HPMC ine zvivakwa zvemvura zviri nani uye zvakakora zvivakwa, saka zvinoratidzira kusimba kwakasimba uye anti-sag zvivakwa muongongori. Inogona kuchengetedza yakanaka yekuchengetwa kwemvura pakutamba kwakakwirira uye kudzivirira mvura mukongiri kubva mukubuda nekukurumidza, nekudaro kuderedza kuitika kwemaza. Mukuwedzera, HPMC inogona zvakare kunonoka kukurumidza kwekumhanya kweiyo hydration maitiro, kubvumira kongiri yekuve nenguva yekuyambira uye kufambisa kuvaka.
3. HydroxyTHYL Cellulose (Hec, HydroxyTHYL Cellulose)
HydroxytHyl cellulose inogadzirwa nekuunza hydroxyl mapoka (-ch2ch2oh) mu cellulose mamorekuru. Basa guru reHec mukongiri ndeyekukanda uye kugadzirisa zvinhu zvinosungwa zvekongiri. Kuenzaniswa nedzimwe cellulose etana, hec yakagadzikana pasi pemamiriro ezvinhu eAlkaline, saka inoshandiswa zvakanyanya mukongiri. Inogona kuvandudza mashandiro eAnti-Sag of concrete uye wedzera simba rekubatanidza kongiri. Kunyanya kugadzirira-kongiri-kongiri inoda kuchengetedza kwenguva refu kana kufambisa, hec kunogona kudzivirira kunyatso dumbu uye kubuda ropa.
4. Hydroxyprupyl cellulose (HPC, hydroxypropyl cellose)
Hydroxyprupyl Cellulose inogadzirwa nekuunza hydroxyprupropropyl group (-ch2chohch3) muCellulose Molecule. Zvakafanana neHPMC, HPC zvakare ine yakanaka yakakora uye yekuchengetwa kwemvura zvivakwa. Mukuwedzera, HPC zvakare ine yakanaka yekukudza uye firimu-inoumba midziyo, iyo inogona kuvandudza kupaza kupokana uye kusimba kwekongiri. Pasi pemamiriro ekunze epamusoro, HPC inogona kuderedza zvakanyanya kumvura kubhururuka mumakongiri, nekudaro kudzivirira kongiri yekupaza kongiri.
5. HydroxytHyl methyl cellelose (hemc, hydroxythell methyl cellelose)
HydroxyTHEthylmethylcellose inogadzirwa nekuunza hydroxylsl mapoka mu methylceulose. Hemc inosanganisa hunhu hwehwanda uye mc, ine yekuchengetwa kwemvura yakanaka uye inokonzeresa zvivakwa, uye zvinogona zvakare kuvandudza basa rekushanda uye kusimba kwekongiri. Iyo inoshandiswa zvakanyanya mukongiri, kunyanya mukuzvimiririra mauto uye inopisa insolation muchipenga. Hemc inogona kuvandudza zvinobudirira kuita basa, kuderedza kuneta kunonyorovera mumotokari, uye kudzivirira marara mushure mekuoma.
6. Ethyl Cellulose (EC, Ethyl Cellulose)
Ethylcellose inogadzirwa nekutsiva mapoka ehydroxyl muCellulose Molecule neEthoxy mapoka (-oc2h5). EC haiwanzo kushandiswa muonghi, asi inotora basa rakakosha mujongwe rakakosha senge rakanyanya-simba kongiri uye kuzvimanikidza kongiri. EC ine yakanaka yakakora uye yekubatanidza zvivakwa uye inogona kuvandudza simba uye kupenga kuramba kongiri. Mukuwedzera, EC zvakare ine yakanaka yemakemikari kuramba uye inogadziriswa yekudzikama, saka inogona kushandiswa zvinobudirira mune dzimwe nharaunda dzinokosha.
7. Methyl hydroxylyl cellulose (Mhec, methyl hydroxyll cellulose)
MetHyl Hydroxyll CellerHose inosanganisa hunhu hweMC uye hec uye ane yakanaka kuremerwa, kuchengetwa kwemvura uye ductifity. Basa guru reMheC muKongiri ndiko kuvandudza midziyo yekubatanidza uye kupaza kuramba kongiri. Izvo zvinonyanya kushandiswa zvakanyanya mukuzvimiririra kongiri uye kugadziriswa motsi.
Cellulose ana vana vanoshandiswa zvakanyanya muongiri uye vane akasiyana siyana. Mhando dzakasiyana dze cellulose ethers dzine zvimiro zvakasiyana zvemakemikari uye zvivakwa zvemuviri uye zvinogona kuita zvinodiwa zvemapurojekiti akasiyana. Kusarudza iyo chaiyo cellulose mhando inogona kuvandudza zvakanyanya kugona, simba uye kusimba kwekongiri, nekudaro zvichikura hunhu uye kuvimbika kwemabasa ekuvaka. Mune zvinoshanda zvinoshanda, zvinodikanwa kusarudza zvine musoro uye dosage ye cellulose ether zvichibva pane chaiyo yeinjiniya zvinodiwa uye mamiriro ekuvaka kuti awane zvakanakisa kushandisa.
