Yiziphi izinhlobo ze-polymer powder (RDP) ezihlakazeka kabusha ezikhona?

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: Inikeza ukuqina okuhle nokuvumelana nezimo, ezifanele 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 kudaka lokuhlobisa, izinamathiselo zamathayili, 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 zamathayela, 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 emigqonyeni 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.).

Redispersible latex powder 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.
