I-polymer powder ehlakazeka kabusha

I-re-dispersible polymer powder (RDP) iwuhlobo lwempushana eyomile ye-polymer yokwenziwa engaxutshwa kalula namanzi ukuze yakhe i-polymer dispersion. I-RDP ijwayele ukusetshenziswa njengesengezo ezintweni zokwakha ezihlukahlukene, okuhlanganisa udaka oluxutshwe okomile, izinto zokunamathisela zamathayela, kanye nezinhlelo zangaphandle ze-insulation and finishing systems (EIFS), ngenxa yezakhiwo zayo ezinhle kakhulu, njengokusebenza okuthuthukisiwe, ukunamathela, kanye nokuguquguquka.

I-RDP yenziwe ngama-polymers okwenziwa ahlukahlukene, njenge-vinyl acetate-ethylene (VAE), i-vinyl acetate-versatile monomer (VeoVa), nama-acrylics. Lawa ma-polymer enziwa i-polymers endaweni enamanzi ukuze akhe i-latex, bese yomiswa bese igaywa ibe yimpushana ecolekile. Impushana ingase ihlakazwe kalula emanzini ukuze yakhe ukuhlakazeka kwe-polymer okuzinzile.

Izakhiwo ze-RDP zincike ohlotsheni lwe-polymer esetshenzisiwe, izinga le-polymerization, ukusatshalaliswa kosayizi wezinhlayiyana, kanye nokuba khona kwezinye izithasiselo. Ngokuvamile, i-RDP inokumelana kahle namanzi, ukuguquguquka, ukunamathela, nokuhambisana nezinye izinto zokwakha. Uhlobo lwempushana lwe-RDP luvumela futhi ukugcinwa kalula, ukuthutha, nokuphatha.

Odakeni oluxutshwe okomile, i-RDP isetshenziselwa ukuthuthukisa ukusebenza, ukunamathela, kanye nokuguquguquka kodaka. I-RDP ingathuthukisa ukugcinwa kwamanzi kodaka, okuvumela ukusebenza kangcono kanye nokwanda kwesikhathi sokuvula. Ukunamathela okuthuthukisiwe okuhlinzekwa yi-RDP nakho kungakhuphula amandla esibopho phakathi kodaka ne-substrate, okuholela ekuqedeni okuhlala isikhathi eside nokuhlala isikhathi eside.

Ezinamathiselwe zamathayili, i-RDP isetshenziselwa ukuthuthukisa amandla ebhondi nokuguquguquka kokunamathelayo. Amandla ebhondi athuthukisiwe ahlinzekwa yi-RDP angakhuphula ukumelana namandla okugunda kanye nokuxebula, okuholela kusibopho esiqinile nesihlala isikhathi eside phakathi kwethayela ne-substrate. Ukuguquguquka okuthuthukisiwe okuhlinzekwa yi-RDP kungasiza futhi ukumunca izingcindezi ezibangelwa ukushintsha kwezinga lokushisa kanye nomswakama, ukwehlisa ingozi yokuqhekeka noma i-delamination.

Ku-EIFS, i-RDP isetshenziselwa ukuthuthukisa ukunamathela, ukuguquguquka, nokumelana nesimo sezulu sohlelo. Ukunamathela okuthuthukisiwe okunikezwa i-RDP kungakhuphula amandla ebhondi phakathi kwebhodi lokufakwa ngaphakathi kanye ne-substrate, kuyilapho ukuguquguquka okukhulayo kungasiza ekubambeni izingcindezi ezibangelwa ukwanda nokufinyela okushisayo. Ukumelana kwamanzi okuhlinzekwa yi-RDP kungasiza futhi ukuvimbela ukungena kwamanzi futhi kunciphise ingozi yomonakalo obangelwa imijikelezo yokuncibilika kweqhwa.

Ukusetshenziswa kwe-RDP ezintweni zokwakha kunezinzuzo eziningana. Okokuqala, i-RDP ingathuthukisa ukusebenza kwezinto, okuholela ekuqedeni okuhlala isikhathi eside nokuhlala isikhathi eside. Okwesibili, i-RDP ingathuthukisa ukusebenza nokuphathwa kwezinto, inciphise ubungozi bamaphutha futhi ithuthukise ukukhiqiza. Okokugcina, i-RDP ingaphinde ithuthukise ukusebenza kwemvelo kwezinto zokwakha, njengokunciphisa inani lezinto eziphilayo ezishintshashintshayo (VOCs) ezikhishwa ngesikhathi sokufakwa.

Sengiphetha, i-re-dispersible polymer powder (RDP) iyisengezo esiguquguqukayo nesisetshenziswa kabanzi ezintweni zokwakha. I-RDP ingathuthukisa ukusebenza, ukunamathela, kanye nokuguquguquka kodaka oluxutshwe okomile, izinto zokunamathisela zamathayili, ne-EIFS, okuholela ekuqedeni okuhlala isikhathi eside nokuhlala isikhathi eside. Ukusetshenziswa kwe-RDP ezintweni zokwakha kunezinzuzo ezimbalwa, okuhlanganisa ukusebenza okuthuthukisiwe, ukusebenza kahle, nokusebenza kwemvelo.
