Kuwedzera mapolymers anogona kuvandudza kusamira, kuoma, kutsemuka kuramba uye kukanganisa kuramba kwedhaka uye kongiri.Permeability uye zvimwe zvinhu zvine mhedzisiro yakanaka.Kuenzaniswa nekuvandudza simba rekushanduka uye kusungirirwa kwesimba redhaka uye kuderedza brittleness yaro, mhedzisiro ye redispersible latex powder pakuvandudza kuchengetwa kwemvura kwedhaka uye kusimbisa kubatana kwayo kunogumira.
Redispersible polymer poda inowanzogadziriswa nekupfapfaidza kuomesa nekushandisa mamwe emulsion aripo.Iyo nzira ndeyekutanga kuwana polymer emulsion kuburikidza neemulsion polymerization, uye wozoiwana kuburikidza nekupfapfaidza kuomesa.Kuti udzivise kuungana kwelatex poda uye kuvandudza mashandiro asati apfapfaidza, zvimwe zvinowedzera zvinowanzowedzerwa, senge bactericides, spraying drying additives, plasticizers, defoamers, nezvimwewo, panguva yekupfapfaidza kuomesa, kana ichangopedza kuomeswa.Mushandi wekusunungura anowedzerwa kudzivirira kuungana kwehupfu panguva yekuchengetedza.
Nekuwedzera kwezviri mukati redispersible latex poda, iyo system yese inokura yakananga kupurasitiki.Kana iri yakakwira latex poda yemukati, chikamu chepolymer mudhaka rakarapirwa zvishoma nezvishoma chinodarika iyo inorganic hydration chigadzirwa, dhaka rinopinda shanduko yemhando uye rinova rakasimba muviri, uye iyo hydration chigadzirwa chesimende inova "yekuzadza"..Iyo firimu yakaumbwa neiyo redispersible latex poda yakagoverwa pachiratidziro inoita rimwe basa rakakosha, ndiko kuti, kusimudzira kunamatira kune zvakabatika zvinhu, izvo zvakakodzera kune dzimwe nzvimbo dzakaoma-kunamira, dzakadai seyakanyanya kuderera kunyura kwemvura kana Kusiri- zvinonwisa mvura (zvakadai sekongiri yakatsetseka uye simende zvinhu, mahwendefa esimbi, zvidhinha zvine homogeneous, vitrified brick surfaces, nezvimwewo) uye organic material surfaces (zvakadai seEPS boards, plastiki, nezvimwewo) zvinonyanya kukosha.Nekuti kusungirirwa kweanonamira kune zvigadzirwa kunowanikwa kuburikidza nemusimboti wekumisikidza kwemuchina, ndiko kuti, iyo hydraulic slurry inopinda mukati memipata yezvimwe zvinhu, zvishoma nezvishoma inoomesa, uye pakupedzisira inosungirira dhaka kwairi sekiyi yakadzikwa mukiyi.Kumusoro kwechinyorwa, chepamusoro chakaoma-ku-chisungo chepamusoro, hachikwanisi kupinda mukati memukati mechinhu kuti chigadzire yakanaka mechanical embedding, kuitira kuti dhaka rine chete inorganic adhesives risati ranyatsobatanidzwa kwariri, uye kusungirirwa. nzira yepolymer yakasiyana., Iyo polymer inosungirirwa pamusoro pezvimwe zvinhu ne-intermolecular force, uye haibvi pane porosity yepamusoro (zvechokwadi, iyo yakaoma yepamusoro uye iyo yakawedzera yekubatana kwepamusoro ichavandudza kunamatira).
