Redispersible latex poda ihupfu inowanikwa nekupfapfaidza-kuomesa emulsion yepolymer uye wobva wawedzera zvinhu zvakagadziridzwa, izvo zvinogona kuparadzirwa zvakare kuita emulsion kana yasangana nemvura. Redispersible latex powder inonyanya kushandiswa sekuwedzera kune yakaoma-yakavhenganiswa dhaka, iyo ine mabasa ekuvandudza kushanda kwedhaka, kuvandudza fluidity, kuvandudza kubatana, uye kuwedzera simba rekubatanidza. Irwo rudzi rutsva rwezvinhu zvakatipoteredza. Parizvino, latex poda inoda kuwedzerwa kune tile bonding, ekunze madziro ekudzivirira, self-leveling, putty poda, nezvimwe kuvandudza kubatana uye sag kuramba kwedhaka.
Iyo polymer emulsion inoshandiswa mune redispersible latex poda inonyanya kuumbwa emulsion yepolymer inoumbwa nekuwedzera imwe kana maviri monomers kune vinyl acetate semonomeri muChina. Parizvino, vinyl acetate-ethylene copolymer emulsion, vinyl acetate - Kunyanya ethylene tertiary carbonate copolymer emulsion, additives ichawedzerwa kune latex powder inogadzirwa kuti ivandudze anti-caking uye redispersibility. Zvisinei, nekuda kwechimiro chevinyl acetate, simba rayo rekutanga uye simba rekuporesa mvura hazvina kunaka maererano nekunamatira kumapuranga ekudzivirira uye simenti substrates.
Acrylic emulsion ine mvura yakanaka inodzivirira uye inoshandiswa zvakanyanya muindasitiri yezvivakwa zvekuvaka, asi kuomesa kwayo kwakananga uye kupfapfaidza hupfu haina kukura, uye chikamu chayo mu redispersible emulsion poda idiki kwazvo, uye kunamatira kwe acrylic emulsion hakuna kunaka, uye i kunamira kudhaka. Kusakwana kwekuvandudzwa kwesimba rekubatanidza kunoderedza kushandiswa kwema acrylic emulsions.
Chinangwa cheiyo novel acrylic latex poda uye nzira yekugadzirira yacho kuwana zvigadzirwa zve latex poda zvine simba rakabatana uye kunamatira kwakanaka.
1. Iro redispersible latex powder ine hutano hwakanaka, hunogona kuvandudza kuwirirana kwekuvaka dhaka, kuvandudza kusungirirwa pakati pedhaka uye nheyo yezvinhu, nekuvandudza kushanda. Inokodzera zvivakwa zvekuvaka uye dhaka zvinoda kusimba kwepamusoro. munda, tarisiro yemusika yakakura.
2. Mukugadzirwa kweiyo redispersible latex powder, zvakasiyana-siyana zvepolymer emulsion inobva pa acrylic emulsion inosarudzwa uye yakasanganiswa maererano nechiyero chakakodzera, iyo inogona kupa kutamba kwakazara kune avo vakasiyana, kuvandudza kushanda kwelatex powder, uye. wedzera chiyero che latex powder. chiyero chekushandisa.
3. Mukugadzirira kweiyo redispersible latex powder, mvura yepfapfaidzo inopisa zvakananga nekupisa kwepaIndaneti, iyo inovandudza redispersibility ye latex powder.
4. Muchigadziro cheiyo redispersible latex powder, marudzi maviri emusanganiswa we calcium carbonate, talcum powder, kaolin uye silicon dioxide inosarudzwa se anti-caking agents ane huwandu hwe1: 1-2, kuitira kuti latex powder. zvimedu Kuputira kwakawedzera yunifomu uye anti-caking pfuma ye latex powder inovandudzwa.
5. Muchigadziro chekugadzirisa redispersible latex powder, imwe kana musanganiswa wesilicone defoamer uye mineral oil defoamer inosarudzwa se defoamer pahuwandu hwehuwandu hwe1: 1, iyo inovandudza The film-forming property ye latex powder. inovandudza kusimba kwechisungo chedhaka.
6. Nzira yekugadzirira ye redispersible latex powder iri nyore uye iri nyore kuona maindasitiri.
