Indasitiri yekuvaka iri kuramba ichishanduka, ichitsvaga zvinhu zvitsva zvekuvandudza mashandiro ematokari ekuvaka. Imwe nyaya iri kugamuchira kutariswa kwakawanda ndeye vinyl acetate-ethylene (VAE) redispersible polymer poda (RDP). Iyi poda inosiyana-siyana yakaratidza kukosha mukuvandudza mashandiro emhando dzakasiyana dzemateki ekuvaka, ichipa kuwedzera kuchinjika, kunamatira uye kusimba.
1. Nhanganyaya:
Kudiwa kwezvinhu zvepamusoro-soro zvekuvaka zvakakonzera kutsvaga kwekuwedzera kwekuwedzera, uye VAE RDP powder yakave yakakosha mumutambo uyu. Ichi chikamu chinopa mhedziso yenheyo dziri shure kweVAE RDP poda, kuumbwa kwayo uye kudzoreredzwa kwayo.
2. Kuumbwa uye zvivakwa zveVAE RDP poda:
Kunzwisisa kuumbwa uye zvivakwa zveVAE RDP poda kwakakosha kuti unzwisise maitiro ayo pamatope ekuvaka. Ichi chikamu chinotarisa muchimiro chemolecular, particle size distribution, uye zvimwe zvakakosha zvinhu zvinoita kuti VAE RDP powder ive yekuwedzera inokosha.
3. Redispersion mechanism:
Chimwe chezvinhu zvinosiyanisa zveVAE RDP powder ndiko kukwanisa kwayo kuparadzirwa mumvura mushure mekuoma. Ichi chikamu chinoongorora maitiro ezve dispersibility, kujekesa zvinhu zvinopesvedzera nzira yekudzoreredza uye kukosha kwenzvimbo iyi mukuvaka zvikumbiro.
4. Kushandiswa mune simende-based mortar:
VAE RDP poda inoshandiswa zvakanyanya mumasimende-based mortars, kuwedzera maitiro ayo akawanda. Ichi chikamu chinokurukura kuti VAE RDP inovandudza sei kunamatira, kushanduka uye kusagadzikana kwemvura kwemasimende-based mortars, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekuvaka.
5. VAE RDP mune gypsum-based mortar:
Gypsum-based mortars ine yakasarudzika zvinodiwa uye VAE RDP poda inoratidzirwa kuzadzisa izvi zvinodiwa zvakanyanya. Ichi chikamu chinoongorora mupiro weVAE RDP kune gypsum-based mortars, ichitarisa pakuvandudzwa kwekushanda, kutsemuka kuramba uye kusimba kwese.
6. Kushandiswa kweVAE RDP mumatairi e ceramic adhesives:
Mataira anonamira anoita basa rakakosha mukuvaka kwemazuva ano uye kuwedzera kweVAE RDP poda kunounza zvakakosha. Ichi chikamu chinokurukura kuti VAE RDP inokwidziridza sei chisungo simba, yakavhurika nguva uye shear simba remataira anonamira, zvichibatsira kuwana yakavimbika uye yakasimba yekuisa.
7. Soka inozvimisa ine VAE RDP:
Iko kudiwa kwemadhaka ekuzvimiririra kuri kuwedzera uye VAE RDP hupfu chinhu chakakosha mukugadzira zvinhu izvi. Ichi chikamu chinoongorora kuti VAE RDP inogona sei kuvandudza kuyerera, kuyera kuita uye kupedzisa kwepamusoro kwezvigadziriso zvedhaka.
8. Sustainable Buildings neVAE RDP:
Tichipesana nemashure ekuwedzera kwekutarisa kwekusimba muindasitiri yekuvaka, VAE RDP poda inomira pachena seyekuwedzera nharaunda. Ichi chikamu chinokurukura kuti kushandiswa kweVAE RDPs, yakasanganiswa neyakasvibirira kuvaka maitiro, inogona kubatsira kuderedza kukanganisa kwezvakatipoteredza.
9. Matambudziko nekufunga:
Kunyange zvazvo VAE RDP poda ichipa zvakawanda zvakanakira, zvakakosha kugadzirisa zvinogona kuitika uye kufunga mukushandiswa kwayo. Ichi chikamu chinoongorora zvinhu zvakaita sekuenderana nezvimwe zvinowedzera, mamiriro ekuchengetera, uye anogona kusangana neakasiyana edhaka zvikamu.
10. Mafambiro nebudiriro:
Sezvo tsvakiridzo yezvivakwa zvekuvaka uye budiriro ichienderera mberi, chikamu ichi chinofungidzira mafambiro emangwana uye zvingangoitika zvine chekuita neVAE RDP poda. Inokurukura nzvimbo dzekuwedzera kuongorora uye hunyanzvi hwekusangana nekuchinja kweindasitiri zvinodiwa.
11. Mhedziso:
Mukupedzisa, VAE RDP poda inova inochinja-chinja uye yakakosha yekuwedzera kune akasiyana matope ekuvaka. Hunhu hwayo hwakasiyana hunobatsira kuvandudza mashandiro, kusimba uye kusimba. Ichi chinyorwa chinopa tarisiro yakazara yeVAE RDP poda, mashandisiro avo uye kugona kwavo kune ramangwana rezvinhu zvekuvaka.
