Indlela yokusebenza ye-Redispersible Polymer Powder (RDP)

I-Redispersible Polymer Powder (RDP)i-polymer powder ephezulu yamangqamuzana, ngokuvamile eyenziwa nge-polymer emulsion ngokumisa isifutho. Inempahla ye-redispersibility emanzini futhi isetshenziswa kabanzi ekwakhiweni, ekubanjeni, ekunamathiseleni nakwezinye izinkambu. Indlela yokusebenza ye-Redispersible Polymer Powder (RDP) ifinyelelwa ngokuyinhloko ngokulungisa izinto ezisekelwe kusimende, ukuthuthukisa amandla okubopha, nokuthuthukisa ukusebenza komsebenzi wokwakha.

1. Ukwakheka okuyisisekelo kanye nezakhiwo ze-Redispersible Polymer Powder (RDP)

Ukwakhiwa okuyisisekelo kwe-Redispersible Polymer Powder (RDP) i-polymer emulsion, evame ukwenziwa i-polymerized kusuka kuma-monomers afana ne-acrylate, i-ethylene, ne-vinyl acetate. Lawa ma-molecule e-polymer akha izinhlayiya ezinhle ngokusebenzisa i-emulsion polymerization. Phakathi nenqubo yokumisa isifutho, amanzi ayasuswa ukuze enze i-amorphous powder. Lezi zimpushana zingasatshalaliswa kabusha emanzini ukuze zenze ama-polymer dispersions azinzile.

Izici eziyinhloko ze-Redispersible Polymer Powder (RDP) zifaka:

Ukunyibilika kwamanzi kanye nokuhlakazeka kabusha: Kungahlakazwa ngokushesha emanzini ukwenza i-polymer colloid efanayo.

Izakhiwo ezithuthukisiwe zomzimba: Ngokwengeza i-Redispersible Polymer Powder (RDP), amandla okubopha, amandla aqinile kanye nokumelana nomthelela wemikhiqizo efana nezinto zokumboza nezisindo kuthuthukiswa kakhulu.

Ukumelana nesimo sezulu nokumelana namakhemikhali: Ezinye izinhlobo ze-Redispersible Polymer Powder (RDP) zinokumelana kahle kakhulu nemisebe ye-UV, ukugqwala kwamanzi kanye namakhemikhali.

2. Indlela yokusebenza ye-Redispersible Polymer Powder (RDP) ezintweni ezisekelwe kusimende

Amandla okubopha athuthukisiwe Indima ebalulekile edlalwa i-Redispersible Polymer Powder (RDP) ezintweni ezisekelwe kusimende ukuthuthukisa amandla ayo okubopha. Ukusebenzisana phakathi kwe-cement paste kanye ne-polymer dispersion system kwenza izinhlayiya ze-polymer zinamathele ngokuphumelelayo ebusweni bezinhlayiya zikasimende. Kusakhiwo esincane sikasimende ngemva kokuqina, ama-molecule e-polymer athuthukisa amandla okubopha phakathi kwezinhlayiya zikasimende ngokusebenzisa isenzo sokuhlangana kobuso, ngaleyo ndlela athuthukise amandla okubopha namandla acindezelayo ezinto ezisekelwe kusimende.

Ukuvumelana nezimo okuthuthukisiwe nokumelana nokuqhekeka I-Redispersible Polymer Powder (RDP) ingathuthukisa ukuguquguquka kwezinto ezisekelwe kusimende. Lapho izinto ezisekelwe kusimende zomile futhi ziqiniswa, ama-molecule e-polymer kunamathiselwe usimende angakha ifilimu ukwandisa ukuqina kwento. Ngale ndlela, udaka lukasimende noma ukhonkolo alujwayele ukuqhekeka lapho lungaphansi kwamandla angaphandle, okuthuthukisa ukumelana nokuqhekeka. Ngaphezu kwalokho, ukwakheka kwefilimu ye-polymer kungabuye kuthuthukise ukuguquguquka kwezinto ezisekelwe kusimende endaweni yangaphandle (njengokushintsha komswakama, izinguquko zokushisa, njll.).

Ukulungisa ukusebenza kokwakhiwa Ukwengezwa kwe-glue powder ehlakazeka kabusha kungathuthukisa ukusebenza kokwakhiwa kwezinto ezisekelwe kusimende. Isibonelo, ukwengeza impushana yeglue ehlakazeka kabusha odakeni oluxubile kungathuthukisa kakhulu ukusebenza kwayo futhi kwenze inqubo yokwakha ibe bushelelezi. Ikakhulukazi ezinqubweni ezifana nokudweba odongeni nokunamathisela amathayili, uketshezi nokugcinwa kwamanzi kwe-slurry kuyathuthukiswa, kugwenywe ukwehluleka kokubopha okubangelwa ukuhwamuka kwamanzi ngaphambi kwesikhathi.

Ukuthuthukisa ukumelana kwamanzi nokuqina Ukwakhiwa kwefilimu ye-polymer kungavimbela ngokuphumelelayo ukungena kwamanzi, ngaleyo ndlela kuthuthukise ukumelana kwamanzi kwezinto. Kwezinye izindawo ezinomswakama noma ezifakwe emanzini, ukungezwa kwama-polymers kungabambezela inqubo yokuguga yezinto ezisekelwe kusimende futhi kuthuthukise ukusebenza kwazo kwesikhathi eside. Ngaphezu kwalokho, ukuba khona kwama-polymers nakho kungathuthukisa ukumelana nesithwathwa kwezinto, ukumelana nokugqwala kwamakhemikhali, njll., futhi kwandise ukuqina kwesakhiwo sokwakha.

3. Ukusetshenziswa kwe-Redispersible Polymer Powder (RDP) kweminye imikhakha

Udaka oluxutshwe okomile Odakeni oluxutshwe okomile, ukungezwa kwe-Redispersible Polymer Powder (RDP) kungathuthukisa ukunamathela, ukumelana nokuqhekeka nokusebenza kokwakhiwa kodaka. Ikakhulukazi emikhakheni yesistimu yokufaka udonga yangaphandle, ukubopha amathayela, njll., ukwengeza inani elifanele le-Redispersible Polymer Powder (RDP) kufomula yodaka exutshwe okomile kungathuthukisa kakhulu ukusebenza kanye nekhwalithi yokwakha yomkhiqizo.

Izembatho ze-Architectural Redispersible Polymer Powder (RDP) zingathuthukisa ukunamathela, ukumelana kwamanzi, ukumelana nesimo sezulu, njll. kwezingubo zezakhiwo, ikakhulukazi ezimbotsheni ezinezidingo zokusebenza eziphezulu ezifana nezindonga zangaphandle kanye nezingubo zaphansi. Ukwengeza i-Redispersible Polymer Powder (RDP) kungathuthukisa ukwakheka kwayo kwefilimu nokunamathela futhi kunwebe impilo yesevisi yokumboza.

Izinamathiselo Kweminye imikhiqizo enamathelayo ekhethekile, njengezinamatheliso zamathayili, izinamatheliso zegypsum, njll., ukwengeza i-Redispersible Polymer Powder (RDP) kungathuthukisa kakhulu amandla okubopha futhi kuthuthukise ububanzi obusebenzayo nokusebenza kokwakhiwa kokunamathelayo.

Izinto ezingangeni manzi Ezintweni ezingangeni manzi, ukwengezwa kwama-polymers kungakha isendlalelo sefilimu esizinzile, kuvimbele ngokuphumelelayo ukungena kwamanzi, futhi kuthuthukise ukusebenza okungangeni manzi. Ikakhulukazi kwezinye izindawo ezidingeka kakhulu (ezifana nokuvimbela amanzi engaphansi, ukuvimbela amanzi ophahleni, njll.), ukusetshenziswa kwe-Redispersible Polymer Powder (RDP) kungathuthukisa kakhulu umphumela wokuvimbela amanzi.

Indlela yokusebenza yeI-RDP, ikakhulukazi ngokusebenzisa izici zayo ze-redispersibility kanye ne-polymer yokwenza ifilimu, inikeza imisebenzi eminingi ezintweni ezisekelwe kusimende, njengokuthuthukisa amandla okubopha, ukuthuthukisa ukuguquguquka, ukuthuthukisa ukumelana kwamanzi, nokulungisa ukusebenza kokwakhiwa. Ngaphezu kwalokho, iphinde ibonise ukusebenza okuhle kakhulu emikhakheni yodaka oluxutshwe okomile, ukumbozwa kwezakhiwo, izinamathiselo, izinto ezingenamanzi, njll. Ngakho-ke, ukusetshenziswa kwe-Redispersible Polymer Powder (RDP) ezintweni zokwakha zanamuhla kubaluleke kakhulu.
