Ukusetshenziswa kwe-polymer powder ehlakazekile ensimini yokwakha

I-PolyMer Powder evuselelayo yesengezo esikhulu sodaka olomile olungiselelwe njengokwenza usimende-based noma i-gypsum-based.

I-Teatisperible Latex Towdex iyi-emulser esomile futhi ehlanganiswe kusuka ku-2um yokuqala ukwakha izinhlayiya eziyindilinga ze-80 ~ 120um. Ngoba izikhala zezinhlayiya zihlanganiswe nge-inorganic, ehlulekile ukwakheka okuvinjelwe, sithola ama-polymer polymer owomile. Zithululelwa kalula noma zigcwele ukugcinwa ezindaweni zokugcina. Lapho i-powder ixutshwe namanzi, usimende noma ngodaka olususelwa ku-gypsum, lungabuyiselwa khona, futhi izinhlayiya eziyisisekelo (2um) kuzo zizophinda zibe ne-latex yasekuqaleni, ngakho-ke ibizwa nge-latex yangempela.

Inokubuyiselwa okuhle, kuhlaze kabusha kube yi-emulsion ekuxhumaneni namanzi, futhi inezakhiwo ezifanayo zamakhemikhali njenge-emulsion yasekuqaleni. Ngokungeza i-polymer esuselwa ku-polymer powder ku-celk-based noma i-gypsum esekelwe ku-powdew udaka, izakhiwo ezahlukahlukene zodaka zingathuthukiswa,

Inkambu yokwakha esetshenzisiwe
1
Uhlelo lwangaphandle lokufakwa kodonga
Kungaqinisekisa ukunamathela okuhle phakathi kweBhodi LaseDitar nePolystyrene kanye nezinye izigatshana, futhi akulula ukuzithoba bese uwa. Ukuguquguquka okuthuthukile, ukumelana nomthelela kanye namandla okuqhekeka okuthuthukile.

2
tile anamathela
Inikeza isibopho esinamandla esinamandla kudaka, enikeza udaka ngohlobo ngokwanele ukulimaza ama-coefficient ahlukene we-appstrate nethayili.

3
ukhozi
I-podemer evuselelayo ye-polymer yenza ukuthi udaka lungafinyeleleki futhi luvimbela ukuphathwa kwamanzi. Ngasikhathi sinye, inama-adhesion amahle ngonqenqema lwethayela, i-shrinkage ephansi nokuvumelana nezimo.

4
Isidumbu se-Interface
Kungavala kangcono igebe le-substrate, linciphise ukumuncwa kwamanzi kodonga, thuthukisa amandla angaphezulu kwe-substrate, futhi uqinisekise ukunamathela kodaka.

5
Udaka olusezingeni lokuzimela
Thuthukisa ukumelana kokuqhekeka kokuzilinganisa, khulisa amandla okubopha ngesendlalelo esingezansi, ukuthuthukisa ukuhlangana, ukumelana nokuqina nokugoba amandla odaka.

6
udaka lwamanzi
I-flewch evuselelayo ye-latex ingathuthukisa ukusebenza; ngaphezu kwalokho kwandisa ukugcinwa kwamanzi; thuthukisa i-hydy menty; Yehlisa i-modulus ye-eastic yodaka futhi uthuthukise ukuhambisana ngesendlalelo sesisekelo. Thuthukisa ukuqina kodaka, wandise ukuguquguquka, ukumelana nokuqhekeka noma unekhono lokubopha.

7
ukulungisa udaka
Qinisekisa ukunamathela kodaka futhi wandise ukuqina kwendawo elungisiwe. Ukwehlisa i-modulus ye-elastic kwenza ukuthi imelane kakhulu nobunzima.

8
bekani
Yehlisa i-modulus ye-eastic yodaka, uthuthukise ukuhambisana nesendlalelo sesisekelo, ukukhulisa ukuguquguquka, ukuqhekeka, ukuthuthukisa ukumelana nempuphu nokumelana nokulimala komswakama, okungasusa ukulimala kwengcindezi yokushisa.
