I-Redisperible Powmer Powder (RDP) iyi-polymer esetshenziswa ezinhlelweni ezahlukahlukene. I-RDP yi-powder engenawo amanzi eyenziwe ngama-polymers ahlukahlukene, kufaka phakathi i-vinyl acetate, i-vinyl acetate ethylene, kanye nama-acrylic reso. I-powder ixutshwe namanzi nezinye izengezo zokwakha i-slurry, esesetshenziswa kuma-substrates ahlukene. Kunezinhlobo eziningana ze-RDP, ngalinye linezakhiwo zalo ezihlukile nokusebenzisa. Kulesi sihloko, sizohlola ezinye zezinhlobo ezivame kakhulu ze-RDP kanye nezicelo zabo.
1. I-Vinyl Acetate Redisperserbleble Pelmer
I-Vinyl Acetate Redisperperblebles iwuhlobo oluvame kakhulu lwe-RDP. Zenziwe nge-vinyl acetate kanye ne-vinyl acetate ethylene copolymer. Izinhlayiya ze-polymer zihlakazeka emanzini futhi zingatholwa kabusha esimweni se-liquid. Lolu hlobo lwe-RDP lunezinhlobonhlobo zezicelo kufaka phakathi izihlanganisi ezihlanganisiwe zomile, imikhiqizo yesimende kanye nezinhlanganisela zokuzilinganisa. Banikeza ukunamathela okuhle kakhulu, ukuvumelana nezimo nokuqina.
2. I-acrylic redisperserble polymer
Ama-acrylic redisperserbles aremismers enziwe nge-acrylic noma i-methacrylic copolymers. Amandla abo ahlukile kanye nokumelana kwe-abrasion kwenza babe fanele izinhlelo zokusebenza lapho ukuqina kubucayi. Zisetshenziselwa ukunamathela kwe-tile, ngaphandle kokufakwa kanye nezinhlelo zokuqeda (ama-EIF), nokulungisa udaka.
3. I-Ethylene-Vinyl Acetate Redisperperbleble Pelmer
Ama-polymers e-Ethylene acetate abuyiselwe kabusha enziwa ku-ethylene-vinyl acetate copolymers. Zisetshenziswa ezinhlobonhlobo zezicelo kufaka phakathi kohlobo lwamakhasa, ama-grouts kanye nama-tile anamathela. Zinokuguquguquka okuhle kakhulu nokunamathelisa ukuze kusetshenziswe ezindaweni eziphakeme kakhulu.
4. STYRENE-Butediene Redisperserbleble Pelmer
Ama-polymers e-Styrerene-Butediene avuselela ama-polymers enziwe avela kuma-styrene-buthadiene copolymers. Zisetshenziswa ezinhlobonhlobo zezicelo kubandakanya nodokotela olungiselelwe ukhonkolo, izinamathiseli zethayela nama-grouts. Banokumelana namanzi okuhle kakhulu kanye nezindawo ezinamathela.
5. I-polymer ephuzekile
I-Polymer Powder e-Emulsifyiable ye-Emulsifyiable iyi-RDP eyenzelwe ukuvulwa kabusha emanzini ngemuva kokomiswa. Isetshenziswa kuzinhlelo zokusebenza eziningi lapho umkhiqizo uvezwa khona emanzini noma umswakama ngemuva kokusebenzisa. Lokhu kufaka phakathi ukunamathela kwamathayili, i-grout, ne-caulk. Banokumelana namanzi okuhle kakhulu nokuvumelana nezimo.
6. I-Hydrophobic redisperserble polymer powler
I-Hydrophobic redisperservible polymer powders eklanyelwe ukukhulisa ukumelana kwamanzi kwemikhiqizo esekwe kore. Ngokuvamile isetshenziswa kuzinhlelo zokusebenza lapho umkhiqizo uzohlangana khona namanzi, njengokufakwa kwangaphandle kanye nezinhlelo zokuqeda (ama-EIFs), ukubhukuda amachibi echibi anamathela kanye nohlobo lokulungiswa kokhonkolo. Inokumelana kahle kwamanzi nokuqina.
I-FATTEX evuselelayo ye-latex iyisitabane esiguquguqukayo esingasetshenziswa ezinhlelweni eziningi. Kunezinhlobo eziningana ze-RDP, ngalinye linezakhiwo zalo ezihlukile nokusebenzisa. Ukunamathela kwabo okuhle kakhulu, ukuvumelana nezimo nokuqina kwenza kube fanele ukusetshenziswa kwemikhiqizo ehlukahlukene. Uma isetshenziswa kahle, ingasiza ekuthuthukiseni ikhwalithi nokuphila isikhathi eside kwemikhiqizo eminingi yokwakha.
