Dry-mix mortar ihupfu hwakapedzwa hunogadzirwa nezvinhu zvinosanganisa simende, ma aggregates, ma fillers, nezvimwe zvinoshandiswa zvakasiyana-siyana muhuwandu hwakakodzera mufekitori. Panguva yekuvaka, inogona kushandiswa nekungowedzera mvura nekukurunga. Kuti isvike pakushanda kwakasiyana-siyana kwekuvaka uye zvinodiwa zvekugara kwenguva refu, dry-mix mortar inowanzoda kuwedzerwa zvimwe zvinhu zvakawanda, izvo cellulose ethers ndeimwe yezvakakosha zve organic polymer additives.
1. Kupatsanurwa kweZvimwe Zvinowedzerwa zveMarara Akasanganiswa Nemvura
1.1. Zvinoita Kuti Mvura Irambe Yakasimba
Mienzaniso inowanzo sanganisirahydroxypropyl methylcellulose (HPMC),hydroxyethyl methylcellulose (HEMC)uyehydroxyethyl cellulose (HEC).
Mabasa Makuru: Kuvandudza kuchengetwa kwemvura yedhaka, kudzivirira kubuda ropa, kuwedzera nguva yekuvhura, uye kuvandudza kugadzikana uye thixotropy panguva yekuvaka.
1.2. Zvinodzora uye Zvinokurumidzisa
Zvinodzora (zvakaita se citric acid ne tartaric acid) zvinononoka kuisa uye zvakakodzera kuvaka pakupisa kwakanyanya kana kushandiswa pakukura. Zvinomhanyisa (zvakaita se chloride salts ne aluminium salts) zvinokurumidzisa kuisa nekuomesa pakupisa kwakaderera.
1.3. Zvinobatsira Kupinza Mhepo Mumhepo
Zvinowanzoshandiswa i lignin sulfonates ne alkyl sulfonates. Zvinovandudza kushanda kwemortar, kuramba chando, uye kuyerera kwemvura mukushandiswa kwayo nekuisa mabubbles madiki.
1.4. Zvinhu Zvinoderedza Mvura
Zvikurukuru, zvinhu zvine naphthalene-based uye polycarboxylic acid-based agents, zvinoderedza kushandiswa kwemvura uye zvinowedzera simba uye huwandu hwemortar.
1.5. Upfu hwePolymer Hunogona Kudzokororwa (RDP)
Inowedzera kuchinjika, kunamira, uye kuramba kutsemuka kwedhaka. Inowanzoshandiswa mukunamatira mataira, masisitimu ekudzivirira madziro ekunze, uye kugadzirisa dhaka.
1.6. Zvimwe Zvinowedzera Basa
Zvinosanganisira zvinodzivisa mildew, zvinodzinga mvura, powders dzinonyungudutsa mumvura, uye starch ethers dzakakora. Izvi zvinosarudzwa zvichienderana nekushandiswa kwazvinoitwa nemota.
2. Maitiro Ekushanda kweCellulose Ethers muDry-Mix Mortars
Cellulose ethers imhando yemapolymers asina ionic anonyungudika mumvura anoshandiswa zvakanyanya mumasystem akasiyana-siyana emota yakasanganiswa nedry-mix. Maitiro ayo makuru anosanganisira:
2.1. Kuchengetwa kweMvura
Mamorekuru e-cellulose ether anosveta uye anovhara mumvura yakasanganiswa, zvichiita kuti ideredze kurasikirwa kwayo nepasi pevhu nemhepo, zvichiita kuti mvura iwande zvakakwana, zvichiita kuti simende iwedzere kusimba.
2.2. Kudzora Kukora uye Kudzora Kuumbwa Kwemaronda
Cellulose ethers dzinogadzira mhinduro ine viscous mumvura, zvichiita kuti dhaka rirambe rakanyorova uye richinamira, zvichiita kuti risatsvedzerere (kusaga) panguva yekushandiswa panzvimbo dzakamira. Uyezve, cellulose ethers dzemhando yepamusoro dzinoratidza thixotropy yakanaka, zvichiita kuti zvive nyore kutsvedzerera uye kugadzirisa dhaka.
2.3. Kushanda Kwakavandudzwa
Kushanda pamwe chete kwekuchengetedza mvura uye hunhu hwe rheological kunoita kuti dhaka rishande kwenguva yakareba uye rinzwe zvakanaka, zvichideredza kuneta panguva yekuisa.
2.4. Kugadzikana Kwakavandudzwa
Kuderedza kupatsanurwa uye kubuda ropa kwezvinhu zvakasanganiswa nezvinhu zvinosimbisa simende kunovandudza kufanana kwedhaka uye kugadzikana kwemhando yekuvaka.
3. Kushandiswa kweCellulose Ethers muMadhaka Akasiyana-siyana Akasanganiswa Nemvura
3.1. Dura reMasonry neDura rePlaster
Zvinoda kuchengetwa kwemvura yakawanda uye kushanda zvakanaka. Cellulose ethers inogona kuderedza kutsemuka nekupwanyika, uye kunatsiridza kunamira.
3.2. Kunamira Mataira
Zvinodiwa kuti mataira asatsvedzerere zvakanaka uye kuti agare kwenguva yakareba. Cellulose ethers inoita kuti mataira asatsvedzerere mushure mekushandisa uye inobvumira nguva yakakwana yekugadzirisa.
3.3. Dura Rinozvienzanisa
Zvinoda kuyerera kwakanyanya uye kugadzikana. Sarudza cellulose ether ine viscosity shoma uye mvura yakawanda kuti usabuda ropa uye kusaparadzaniswa.
3.4. Sisitimu yekudzivirira yekunze (EIFS) Mortar
Kuchengetwa kwemvura kunokanganisa zvakananga kubatana kwebhodhi rekudzivirira kupisa nedhaka. Cellulose ethers inogona kuve nechokwadi chekuti mhando yacho inogara yakafanana panguva yekushandiswa kukuru.
4. Zvaunofanira Kufunga Nezvekusarudza Nekuwedzera
Kusarudzwa kweViscosity: Viscosity yakawanda inopa mvura yakasimba asi inogona kuderedza kushanda; viscosity shoma inopa kuyerera kwakanaka asi inokurumidza kubuda ropa. Kugadziriswa kunofanirwa kuitwa zvichibva pane zvakagadzirwa. Huwandu hwekuwedzera: Kazhinji 0.1% kusvika 0.5% yehukuru hwechinhu chinosimbisa simende. Kuwedzera zvakanyanya kunogona kukanganisa simba uye nguva yekuoma.
Kupararira: Kupararira kwakakwana kunodiwa panguva yekusanganisa mvura yakaoma kudzivirira kuungana kwevhu mushure mekuwedzera mvura.
Kuvandudza mashandiro edhaka rakaoma kunoda sisitimu yekuwedzera inoshanda zvakanaka, uyeether ye cellulosendiyo nzira huru yekugadzirisa zvinhu mukati meiyi sisitimu. Haingovimbisi chete kuti dhaka rinochengetwa mvura uye rinoshanda zvakanaka, asiwo inokanganisa simba remabhondi, kugara kwenguva refu, uye kunaka kwenzvimbo. Nekuwedzera kwezvinodiwa pakuvaka uye kushandiswa kwakapararira kwepfungwa dzinochengetedza simba uye dzinochengetedza nharaunda, kushandiswa kwe cellulose ether mudhaka rakaoma kuchawedzera kusiyanisa uye kunatswa.
