Redispersible latex poda sechinhu chakakosha chekuwedzera chedhaka yakaoma-yakasanganiswa

Redispersible latex poda ihupfu yekuparadzira yakagadzirwa nemodified polymer emulsion nekupfapfaidza kuomesa. Iyo ine yakanakisa permeability uye inogona kudzokororwa mu emulsion yakagadzikana yepolymer mushure mekuburitswa kwemvura. Iyo organic chemistry yakafanana chaizvo neyekutanga moisturizing lotion. Nokudaro, zvinokwanisika kugadzira yakakwirira-yepamusoro yakaoma poda dhaka, nekudaro kuvandudza kushanda kwesamende dhaka.

Redispersible latex powder chinhu chakakosha chinoshanda chekuwedzera kune dhaka. Inogona kuvandudza mashandiro edhaka, kuwedzera simba rekumanikidza resimende dhaka, kuvandudza kusimba kwechisungo chesimende dhaka nemabhodhi akasiyana, uye kugadzirisa kusimba kwesamende dhaka. Kupfava uye kuremara, kusimba simba, kumanikidza simba, abrasion kuramba, ductility, adhesion racing uye mvura-kukiya kugona, uye kuvaka. Pamusoro pezvo, iyo yakasikwa latex poda ine kudzoreredza mvura inogona kuita kuti dhaka resimende rive nekudzivirira kunyorova kwakanaka.

Kuvandudza kubatanidzwa kwesamende dhaka mukuvaka engineering. Mushure meiyo ichangobva kusanganiswa simende dhaka ine yakasikwa latex poda dispersion fluid yaumbwa, iyo yemvura inozodzikira zvishoma nezvishoma nekugayiwa uye kunyudzwa kwemvura pachigadziko, kushandiswa kwekusimbisa reaction, uye kubuda kumhepo. , zvimedu zviri kuswedera zvishoma nezvishoma, mapeji anosvibiswa zvishoma nezvishoma, uye zvishoma nezvishoma akabatanidzwa pamwe chete. Pakupedzisira, iyo polymer inobviswa. Iyo yese maitiro epolymer demulsification yakakamurwa kuita matatu malink. Mune yekutanga moisturizing emulsion, iyo polymer zvimedu zviri muchimiro cheBrownian motion. Famba wakasununguka, pamwe chete nekuputika kwemvura, kufamba kwezvikamu kunowanzoenderana nezvirambidzo zvakawandisa, kushushikana kwepamusoro pemvura uye gasi kunovakurudzira kuti varonge pamwe chete zvishoma nezvishoma, nhanho yechipiri, apo zvidimbu zvinotanga kugunzvana, mambure Maumbirwo mvura volatilizes kuburikidza capillaries, uye mukuru-porous anotsigira simba rakabudiswa pamusoro pezvimedu anokonzera deformation dzinongoitika latex spheres kuita chisungo pamwe chete, uye yasara mvura inozadza pores, uye membrane zvichida kuumbwa. . Yechitatu Nhanho yekupedzisira ndeyekuita kupararira kwemapolymer molecules (dzimwe nguva inonzi self-adhesiveness) kuumba chaiyo inoenderera firimu panguva yedemulsification process.
