Imboni yokwakha iyaqhubeka nokuthuthuka ibe yizinto zokwakha ezisebenza kahle kakhulu, ezisebenzisa amandla kahle, nezihlala isikhathi eside. Izinto zokwakha zendabuko ezisekelwe kusimende zivame ukuba nemikhawulo efana nalokhu:

• Ukuguquguquka okuphansi
• Ukunamathela okubi
• Ukuphuka okuphezulu
• Izinkinga zokuqhekeka
• Ukumelana namanzi okubuthakathaka

Ukuze kunqotshwe lezi zinselele, amafomula esimanje e-dry-mix mortar asebenzisa kakhulu izithasiselo ze-polymer ezithuthukisiwe. Phakathi kwazo,Impuphu yePolymer Ephinde Ihlakazeke (RDP)isibe ngenye yezinto ezibaluleke kakhulu ezisebenzayo.

I-RDP iyimpuphu ye-polymer ecutshungulwe ngokukhethekile engaphinde ihlakazeke emanzini futhi idale kabusha i-polymer emulsion ezinzile. Uma ingezwa ezinhlelweni ezisekelwe kusimende, i-RDP yakha ifilimu ye-polymer eguquguqukayo ethuthukisa kakhulu:

• Amandla okunamathela
• Ukuzivumelanisa nezimo
• Ukumelana nokuqhekeka
• Ukumelana namanzi
• Ukuqina

Namuhla, i-RDP isetshenziswa kabanzi ku:

• Izinamathiseli zethayela
• Izinhlelo zokuqeda ukufakelwa kwangaphandle (i-EIFS)
• I-putty yodonga
• Izinhlanganisela ezizilinganisayo
• Lungisa izimbotshana
• Izimbotshana ezingangeni manzi
• Izinto ezisekelwe ku-gypsum

1. Ukuqonda i-Redispersible Polymer Powder (RDP)

1.1 Iyini i-RDP?

I-Redispersible Polymer Powder iyimpuphu egeleza ngokukhululeka ekhiqizwa yi-spray drying polymer emulsions.

Inqubo yokukhiqiza ngokuvamile ihlanganisa:
