Redispersible latex podaimhando yekunamira kwehupfu inogadzirwa neakakosha lotion pfapfaidzo yekuomesa. Rudzi urwu rwehupfu hunogona kukurumidza kuparadzirwa kuita lotion mushure mekusangana nemvura, uye ine hunhu hwakafanana neyekutanga lotion, ndiko kuti, mvura inogona kugadzira firimu mushure mekubuda. Iyi firimu ine yakakwirira kuchinjika, yakakwirira mamiriro ekunze kuramba uye yakakwirira kunamatira kune akasiyana substrates. Mukuwedzera, latex poda ine hydrophobicity inogona kuita kuti dhaka ive yakanaka isina mvura. Yakaparadzaniswa chena latex ine nguva yakareba yekuchengetedza, inodzivirira antifreeze, uye iri nyore kuchengeta. Kutarisa ruzivo rwakadzama kubva kumadokero.
1, Chii chinonzi redispersible latex poda
Theredispersible latex podachigadzirwa imvura-soluble redispersible powder, iyo yakakamurwa kuva ethylene / vinyl acetate copolymer, vinyl acetate / ethylene tert carbonate copolymer, acrylic acid copolymer, etc. Iyo poda yakanamatira yakagadzirwa mushure mekupfapfaidza kuomesa inoshandisa polyvinyl doro sekudzivirira colloid. Rudzi urwu rwehupfu hunogona kukurumidza kuparadzirwa kuita lotion mushure mekusangana nemvura. Nekuti redispersible latex poda ine yakakwira yekunamira kugona uye yakasarudzika zvimiro, senge kusamira kwemvura, kushanda uye kupisa kupisa, yavo yekushandiswa kwemhando yakakura zvakanyanya.
2, Zvakanakira redispersible latex poda
1. Hapana chikonzero chekuchengeta uye kutakura nemvura, kuderedza mari yekufambisa;
2. Nguva refu yekuchengetedza, anti kutonhora, nyore kuchengeta;
3. Iyo yekurongedza idiki muhukuru, yakareruka muhuremu, uye iri nyore kushandisa;
4. 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.
3, Kushandiswa kwe redispersible latex poda
Redispersible latex podainonyanya kushandiswa mukati: mukati uye kunze kwemadziro emadziro putty powder, ceramic tile adhesive, ceramic tile pointing agent, dry powder interface agent, kunze kwemadziro ekudzivirira dhaka, self-leveling dhaka, kugadzirisa dhaka, dhaka rekushongedza, dhaka risina mvura, kunze kwekuvharidzira yakaoma yakasanganiswa dhaka. Mudhaka, chinangwa ndechekuvandudza brittleness, yakakwira elastic modulus uye kumwe kusasimba kwechinyakare simende dhaka, kuchipa iyo yakanaka kuchinjika uye inosimba yekubatanidza kusimba kuramba uye kunonoka kugadzirwa kwedhaka resimende. Nekuda kwekugadzirwa kweiyo interpenetrating network structure pakati pepolymer nedhaka, firimu repolymer rinoramba riripo rinoumbwa mumapores, kusimbisa kubatana pakati peaggregates uye kuvhara mamwe mapores ari mudhaka, Saka iyo yakagadziridzwa dhaka mushure mekuoma ine kuvandudzwa kukuru mukuita kana ichienzaniswa nesamende dhaka.
