Basa re redispersible latex powder:
1. Theredispersible latex poda (Rigid adhesive powder Neutral rubber powder Neutral latex powder）inoumba firimu mushure mekupararira uye inoshanda sechinhu chinonamira kusimbisa simba rayo. 2. Iyo inodzivirira colloid inobatwa nedhaka system (haizoparadzwi nemvura kana "secondary dispersion" mushure mekunge firimu raumbwa. 3. Iyo firimu-inogadzira polymer resin inogoverwa mudhaka rose sechinhu chekusimbisa, nokudaro kuwedzera kubatanidzwa kwedhaka; iyo redispersible latex poda inonamira yeupfu inogadzirwa nekuomesa lotion (yakakwirira molecular polymer) yakapfapfaidza mushure mekusangana nemvura, upfu uhwu hunogona kukurumidza kuparadzirwa kuumba lotion, uye ine zvinhu zvakafanana yekutanga lotion, ndiko kuti, mvura inogona kuumba firimu mushure mekubuda kwemhepo.
Basa reRDP: kuti uvandudze kupikisa, redispersible latex powder is thermoplastic resin. Ifirimu rakapfava rakaputirwa pamusoro pevhu revhu, iro rinogona kutora kukanganiswa kwemasimba ekunze, kuzorora pasina kukuvara, nekudaro ichivandudza kupikisa kwedhaka. Kuvandudza kupfeka kuramba uye kusimba nekuwedzeraredispersible latex podainogona kuwedzera chisungo chakaomarara pakati pesimende dhaka zvimedu nemafirimu epolymer. Kukwidziridzwa kwesimba rekunamira zvinoenderana nekunatsiridza kugona kwedhaka kuti rimire kushushikana kweshear, kudzikisa chiyero chekupfeka, kunonatsiridza kusapfeka, uye kurebesa hupenyu hwebasa redhaka. Kuvandudza hydrophobicity uye kuderedza kunyura kwemvura, uye kuwedzeraredispersible latex podainogona kuvandudza microstructure yesamende dhaka. Iyo polymer yayo inoumba network isingadzokeri mune simende hydration process, inovhara iyo capillary mune simende gel, inovharira kupinda kwemvura, uye inovandudza kusamira. Kuvandudza simba rekubatanidza uye kubatana kwezvinhu kuburikidza nekushandiswa kweredispersible latex podainoita basa rakakosha mukuvandudza kusimba kwekubatanidza uye kubatana kwezvinhu. Nekuda kwekupinda kwemapolymer particles mu pores uye capillaries ye simenti matrix, yakanaka kubatana kunoumbwa mushure me hydration ne simenti. Iyo yakanakisa kubatanidza simba repolymer resin pachayo inonatsiridza kunamatira kwesimende zvigadzirwa zvedhaka kune substrates, kunyanya simende, inorganic binder, kune huni, faibha, PVC Kuvandudzwa kwekunamira kwakashata kweorganic substrates seEPS ine mhedzisiro yakakosha. Kuvandudza kugadzikana kwechando-thaw zvinobudirira kudzivirira kuputika kwezvinhu, uye iyoredispersible latex podaine mhedzisiro yepurasitiki ye thermoplastic resin yayo, iyo inogona kukunda kukuvadzwa kwekuwedzera kwekupisa uye kuputika kunokonzerwa nekushanduka kwetembiricha pazvinhu zvesamende. Kukunda maitiro ehukuru hwakaoma shrinkage deformation uye nyore kuputika kwechenese sement mortar kunogona kuita kuti zvinhu zviwedzere kushanduka, nokudaro zvichivandudza kugadzikana kwenguva refu kwezvinhu. Kuvandudza kukotama uye kusimba kuramba. Mune yakaomeswa dhizaini yakaumbwa neiyo hydration yesamende dhaka, membrane yepolymer iri elastic uye inochinjika, ichitamba basa rakafanana sechinhu chinofambiswa pakati pemasimende edhaka zvidimbu. Iyo inogona kumira yakakwira deformation mitoro, kuderedza kushushikana, uye kuvandudza tensile uye kukotama kuramba.
Zvakanakira zveredispersible latex poda
Hapana chikonzero chekuchengeta uye kutakura nemvura, kuderedza mari yekufambisa; Nguva refu yekuchengetedza, anti kutonhora, nyore kuchengeta; Iyo yekurongedza idiki muhukuru, yakareruka muhuremu, uye iri nyore kushandisa; Inogona kusanganiswa nemvura-based binder kuti iite synthetic resin modified premix. Kana yakashandiswa, mvura chete inoda kuwedzerwa, iyo isingadzivisi zvikanganiso panguva yekusanganiswa panzvimbo, asiwo inovandudza kuchengetedzwa kwekubata kwechigadzirwa.
