Iyo yakakwirira kuchengetwa kwemvura kwedhaka re plaster, zviri nani here?

Kuchengeta mvura chinhu chakakosha chedhaka dhaka sezvo ichikanganisa kushanda kwayo, nguva yekuisa, uye simba remuchina. Zvisinei, hukama huri pakati pekuchengetedza mvura uye kushanda kwedhaka dhaka hakusi nyore, uye hapana mhinduro chaiyo yekuti iyo yakakwirira yekuchengetedza mvura, zviri nani dhaka repurasita.

Kuchengetedzwa kwemvura (water retention) zvinoreva kugona kwedhaka revhu kuti richengete mvura pasina kubuda ropa kana kupatsanura. Kazhinji, huwandu hwekuchengetedza mvura hunoreva kuti dhaka re plaster rinogona kuchengetedza mvura yakawanda uye rinoramba richishanda kwenguva yakareba, izvo zvinogona kubatsira kune mamwe maapplication. Nekudaro, kuchengetedza mvura yakawandisa kunogona zvakare kutungamirira kumatambudziko akadai sekuderera, kuputika, uye kuderedzwa kwesimba remagetsi, izvo zvinogona kukanganisa kuita kweplaster mortar.

Kana zvasvika pakuchengetwa kwemvura yeplaster mortar, iyo yakaringana inoenderana nezvinhu zvakasiyana serudzi rwepurasita, tembiricha yepakati uye hunyoro, nzira yekusanganisa, uye mhedzisiro yaunoda. Semuenzaniso, mumamiriro ezvinhu anopisa uye akaoma, kuchengetwa kwemvura kweplaster mortar kunofanira kunge kwakakwirira kudzivirira kuoma kwakanyanyisa, asi mukutonhora kunotonhora, kuderedzwa kwemvura kunogona kusarudzwa kukurumidzira nguva yekuisa.

Imwe yemabhenefiti makuru ekuchengetedza mvura yakakwira mudhaka dhaka ndeyekuti inogona kuvandudza kushanda, zvichiita kuti zvive nyore kupararira uye kutsvedzerera pamusoro penzvimbo. Izvi zvinogona kubatsira mumashandisirwo anodiwa kutsetseka uye kunyange kupera, senge mukushongedza plastering kana mukugadzirisa madziro akakuvadzwa kana sirin'i. Kuchengetedzwa kwemvura yepamusoro kunogonawo kugadzirisa chisungo pakati pedhaka dhaka uye substrate, ichiwedzera simba rayo rose.

Zvisinei, kuchengetedza mvura yakawandisa kunogonawo kutungamirira kumatambudziko akadai sekuputika, shrinkage, uye kuderedza simba remagetsi. Kana dhaka repurasita rine mvura yakawandisa, zvinogona kutora nguva yakareba kuti zvigadzike uye zviomese, izvo zvinogona kutungamirira mukutsemuka uye kupera. Pamusoro pezvo, iyo yakawedzera mvura inogona kunetesa chisungo pakati pedhaka dhaka uye substrate, izvo zvinogona kuderedza simba rayo rose uye kusimba.

Kuti uwane iyo yakakodzera kuchengetwa kwemvura mune plaster dhaka, zvakasiyana-siyana zvinowedzera zvinogona kushandiswa. Semuenzaniso, kuwedzera cellulose ethers, yakadai semethyl cellulose kana hydroxypropyl methylcellulose, inogona kuvandudza kuchengetedza kwemvura pasina kukanganisa simba remagetsi. Zvimwe zvinowedzera zvakadai semhepo-entraining agents zvinogonawo kushandiswa kuwedzera kushanda uye kuderedza dambudziko rekuputika uye kupera.

Mukupfupisa, hukama pakati pekuchengetedza mvura uye kushanda kweplaster mortar yakaoma, uye hapana mhinduro imwechete-yese-yese yekuti kuchengetwa kwemvura kwakakwirira kuri nani. Iyo yakakodzera kuchengetedza mvura kunoenderana nezvinhu zvakasiyana, uye chiyero chinofanira kurohwa pakati pekushanda, kuseta nguva, uye simba remuchina. Nekunzwisisa zvimiro zvesamende dhaka uye kushandisa zvakakodzera zvinowedzera, zvinokwanisika kuwana yakakwana yekuchengetedza mvura kune yakapihwa application.
