I-Redispersible polymer powder (RDP) iyisengezo se-polymer esibalulekile esisetshenziselwa ukuthuthukisa ukusebenza kwe-cement-based, i-gypsum-based, i-lime-based kanye ne-lime-mortar-based materials. I-RDP ithuthukisa ukusebenza okuphelele kwalezi zinto ngokusebenzisa ukusebenza kwayo kokubopha, ukuqinisa, ukumelana nokuqhekeka, ukumelana namanzi, njll., futhi isetshenziswa kakhulu ezintweni zokwakha.
Izinhlobo eziyinhloko ze-RDP
Izinhlobo ze-RDP zihlukaniswa ngokuyinhloko ngokohlobo lwe-substrate ezakhiwe ngalo, inkambu yesicelo kanye nezici zokusebenza. Ama-RDP ajwayelekile ahlanganisa lokhu okulandelayo:
Uhlobo lwe-ethylene-vinyl acetate copolymer (EVA):
Izici: I-ethylene-vinyl acetate copolymer ingenye yezinhlobo ezivame kakhulu ze-RDP. Inokuguquguquka okuhle kakhulu nokunamathela, futhi inikeza ukumelana kwamanzi okuhle nokumelana nesimo sezulu.
Isicelo: Ikakhulukazi isetshenziswa kuma-adhesives amathayili, izinto ezizilinganisa phansi, izinhlelo zokuvala udonga zangaphandle nezinye izinkambu.
Izinzuzo: Ihlinzeka ngokuqina okuhle nokuvumelana nezimo, ifanele izikhathi ezidinga ukuguquguquka okuthile nokunamathela.
Ukubi: Ngenxa yokuqukethwe kwayo okuphezulu kwe-ethylene, ukusebenza kwayo kungase kungenele kancane kwezinye izinhlelo zokusebenza ezinezidingo zamandla aphezulu.
Uhlobo lwe-Ethylene-vinyl acetate-vinyl acetate terpolymer (VeoVa/EVA):
Izici: Lolu hlobo lwe-RDP lungenisa i-VeoVa (vinyl ester) ngesisekelo se-ethylene ne-vinyl acetate copolymerization, okuthuthukisa ukumelana kwamanzi nokuzinza kwamakhemikhali wento.
Isicelo: Okuvame ukusetshenziswa emigqumeni yangaphandle yodonga kanye nemikhiqizo ye-gypsum, njll.
Izinzuzo: Inokumelana kwamanzi okungcono nokumelana namakhemikhali, ifanele ukusetshenziswa kwangaphandle namakhemikhali anokhahlo.
Ukungalungi: Uma kuqhathaniswa nohlobo lwe-EVA yendabuko, izindleko zingase zibe phezulu kancane.
Uhlobo lwe-styrene-butadiene copolymer (SB):
Izici: Iqukethe ikakhulukazi i-styrene ne-butadiene monomers, futhi inezici ezinhle zokubopha, ukuguquguquka nokuphikiswa kwamanzi.
Isicelo: Isetshenziswa ngokujwayelekile kuma-adhesives amathayili nama-putty aguquguqukayo.
Izinzuzo: Ukubambisana okuhle nokuvumelana nezimo, kanye nokusebenza okuhle kakhulu ekuphikisweni kwamanzi.
Ukungalungi: Ingase iguge ngaphansi kokukhanya kwe-ultraviolet.
Uhlobo lwe-vinyl acetate-ethylene copolymer (VAE):
Izici: Kuyi-copolymer ye-vinyl acetate ne-ethylene, enokuguquguquka okuhle kakhulu nokumelana namanzi.
Isicelo: Ilungele izinamathiselo zamathayili, izinhlelo zokuvala udonga zangaphandle, ukuzilinganisa okusekelwe ku-gypsum, njll.
Izinzuzo: Inikeza ukunamathela okuhle nokumelana namanzi, futhi inokumelana namakhemikhali athile.
Ukubi: Izindleko ziphakeme uma kuqhathaniswa.
Uhlobo lwe-Acrylic copolymer (Acrylic):
Izici: Ingxenye eyinhloko yi-acrylic ester, enokunamathela okuhle kakhulu nokuguquguquka.
Isicelo: Isetshenziswa kabanzi odakeni lokuhlobisa, izinamathiselo zamathayela, i-gypsum nezinye izinto.
Izinzuzo: Ukunamathela okuhle kakhulu nokuguquguquka, nokumelana okuhle kwe-UV.
Ukungalungi: Ngenxa yezindleko eziphezulu zezinto ze-acrylic, izindleko zalolu hlobo lwe-RDP nazo ziphezulu.
Imisebenzi kanye nokusetshenziswa kwe-RDP
Ukusebenza okuthuthukisiwe kokubopha:
I-RDP idlala indima yokuhlanganisa impahla, ithuthukisa ukunamathela kokunamathelayo, futhi ithuthukise ukuhlangana phakathi kwempahla yokwakha ne-substrate.
Izindawo zokufaka isicelo zifaka izinto zokunamathisela zamathayili, izinsimbi zokubopha, njll.
Ukuguquguquka okuthuthukisiwe nokumelana nokuqhekeka: Ngokungeza i-RDP, ukuguquguquka kwezinto ezibonakalayo kuthuthukiswa kakhulu, okusiza ukuvimbela ukuvela kwemifantu.
Okuvame ukusetshenziswa ezinhlelweni zokufakelwa, i-putty eguquguqukayo, izinto zokulungisa, njll.
Ukumelana kwamanzi okuthuthukisiwe nokumelana namanzi:
I-RDP ithuthukisa ukumelana kwamanzi kwento esetshenziswayo, ukuyivumela ukuthi igcine ukusebenza okuzinzile endaweni enomswakama.
Kusetshenziswa emigqumeni engangeni manzi, embongeni yangaphandle, njll.
Ukusebenza kokwakha okuthuthukisiwe:
I-RDP ingathuthukisa ukusebenza kokwakhiwa kwezinto zempushana ezomile, okwenza ukwakhiwa kube lula futhi kusebenze kahle.
Isetshenziswa kabanzi ezintweni ezizilinganisa phansi, okokunamathela, njll.
Ukuqina okuthuthukisiwe nokumelana nesimo sezulu: Ngenxa yokwengezwa kwe-RDP, ukuqina nokumelana nesimo sezulu kwempahla kuba ngcono kakhulu, futhi ingakwazi ukumelana novivinyo lwezindawo ezinokhahlo.
Kusetshenziswa kumasistimu odonga angaphandle, ama-roof coatings, njll.
Imibono yokukhetha i-RDP efanele
Izimo zohlelo lokusebenza:
Khetha uhlobo olufanele lwe-RDP ngokwesimo sohlelo oluthile, isibonelo, izinhlelo zokusebenza zangaphandle zidinga i-RDP enokumelana nesimo sezulu esihle.
Ukulawula izindleko:
Ngokwesisekelo sokuqinisekisa ukusebenza, kuyadingeka ukucabangela izindleko zezinto ezibonakalayo bese ukhetha i-RDP yokonga.
Ukuhambisana:
I-RDP idinga ukuhambisana kahle nezinye izinto ukuze kuqinisekiswe ukuzinza nokusebenza okufanayo kwengxube.
Izidingo zokusebenza:
Khetha uhlobo olufanele lwe-RDP ngokwezakhiwo ezidingekayo (njengokuguquguquka, ukunamathela, ukumelana namanzi, njll.).
I-latex powder e-redispersible idlala indima ebalulekile ezintweni zokwakha zesimanje, futhi izinhlobo zayo ezihlukahlukene zinikeza izixazululo eziguquguqukayo zezidingo ezihlukahlukene zokwakha. Ukukhetha uhlobo olufanele lwe-RDP kungathuthukisa kakhulu ukusebenza kwezinto zokwakha, ngaleyo ndlela kuthuthukise ikhwalithi nokuqina kwamaphrojekthi wokwakha.
