Redispersible polymer hupfui-polymer white powder yakasununguka-inoyerera iyo inogona nyore-emulsified uye yakapararira mumvura kuti iite emulsion yakagadzikana. Inogona kusanganiswa nezvimwe zvinhu zveupfu senge simende, jecha, lightweight aggregate, nezvimwewo mufekitari yekugadzira zvinoenderana nechiyero chakaoma munzvimbo yakaoma kuwana simende yemhando yepamusoro uye iri nyore kushandisa simende yakaoma-yakasanganiswa dhaka, izvo zvinogona kuderedza pa-site kuvaka. Kukanganisa uye kusagadzikana pakusanganisa uye kuyera ne emulsion.
Mabasa matanhatu ezve dispersible polymer poda:
1. Kuvandudza simba rekunamatira uye kubatana
Mune simende yakaoma dhaka zvigadzirwa, zvinonyanya kukosha kuwedzera inoparara polymer poda. Zvinonyatsojeka kuvandudza simba rekubatanidza uye kubatana kwezvinhu. Izvi zvinokonzerwa nekupinda kwemapolymer particles mu pores uye capillaries ye simenti matrix, uye kuumbwa kwesimba rakanaka rakabatana ne simenti mushure me hydration. Nekuda kwekunamira kwakanakisa kwepolymer resin pachayo, inogona kuvandudza kunamatira kwesimende zvigadzirwa zvedhaka kune substrates, kunyanya inorganic binders sesimende inosungirirwa kune organic substrates sehuni, fiber, PVC uye EPS. Kuvandudzwa kwekuita kwakashata kune zvakanyanya kuoneka.
2. Kuvandudza kukotama uye kusagadzikana kwekudzivirira
Mune skeleton yakaoma inoumbwa ne hydration yesamende dhaka, iyo polymer firimu inotenderera uye yakaoma. Pakati pesimende dhaka zvimedu, inoshanda senge inofambiswa yakabatana, iyo inogona kumira yakakwira deformation mitoro uye kuderedza kushushikana, ichiita iyo Tensile uye bending kuramba inovandudzwa.
3. Kuvandudza kukanganisa kwekudzivirira
Redispersible polymer hupfu, thermoplastic resin. Ifirimu rakapfava rakaputirwa pamusoro pezvimedu zvedhaka, izvo zvinogona kutora kukanganiswa kwesimba rekunze uye kuzorora pasina kutyora, nekudaro ichivandudza kupikisa kwedhaka.
4, kunatsiridza hydrophobicity uye kuderedza kuwanda kwemvura
Kuwedzera dispersible polymer poda inogona kuvandudza iyo microstructure yesamende dhaka. Yayo polymer inoumba network isingadzokeri mukati mekuita simende hydration, inovhara capillary mune simenti gel, inovhara kunyura kwemvura, inodzivirira kupinda kwemvura, nekudaro ichivandudza kusamira.
5. Kuvandudza kupfeka kusagadzikana uye kusimba
Kuwedzerwa kwepolymer poda inorasika kunogona kuwedzera chisungo chakaomarara pakati pemasimende evhu resimende uye firimu repolymer. Kukwidziridzwa kwesimba rakabatana kunonatsiridza kugona kwedhaka kuti rimire kushushikana kweshear, kuitira kuti chiyero chekupfeka chideredzwe, kupikisa kwekupfeka kunovandudzwa, uye hupenyu hwebasa hwedhaka hurefu.
6. Kuvandudza chando-thaw kugadzikana uye zvinobudirira kudzivirira kuputika kwezvinhu
Redispersible polymer poda, iyo plasticity ye thermoplastic resin yayo, inogona kukurira kukuvadzwa kwekuwedzera kwekupisa uye kuputika kunokonzerwa nekushanduka kwetembiricha pane zvesimende zvedhaka. Kukunda zvikanganiso zvesamende dhaka rakareruka neyakakura kuomesa shrinkage deformation uye kuputika kuri nyore, zvinogona kuita kuti zvinhu zvishanduke, nokudaro zvichivandudza kugadzikana kwenguva refu kwezvinhu.
