Indlela yokusebenza kwe-Redispersible Polymer Powder (RDP)

Impuphu yePolymer Ephinde Ihlakazeke (RDP)iyimpuphu ye-polymer ephezulu yamamolekyuli, evame ukwenziwa nge-polymer emulsion ngokufutha nge-spray. Inesimo sokuphinde ihlakazeke emanzini futhi isetshenziswa kabanzi ekwakheni, ekumbozeni, ekunamathiseni nakwezinye izinkambu. Indlela yokusebenza kwe-Redispersible Polymer Powder (RDP) itholakala kakhulu ngokushintsha izinto ezisekelwe kusimende, ukuthuthukisa amandla okubopha, kanye nokuthuthukisa ukusebenza kokwakha.

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

Ukwakheka okuyisisekelo kwe-Redispersible Polymer Powder (RDP) yi-polymer emulsion, evame ukwenziwa i-polymer kusuka kuma-monomers afana ne-acrylate, i-ethylene, ne-vinyl acetate. Lawa ma-molecule e-polymer akha izinhlayiya ezincane ngokusebenzisa i-emulsion polymerization. Ngesikhathi senqubo yokomisa nge-spray, amanzi ayasuswa ukuze akhe i-amorphous powder. Lawa ma-powder angaphinde ahlakazwe emanzini ukuze akhe i-polymer dispersions ezinzile.

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

Ukuncibilika kwamanzi kanye nokuphinde kuhlakazeke: Angasakazwa ngokushesha emanzini ukuze akhe i-polymer colloid efanayo.

Izakhiwo zomzimba ezithuthukisiwe: Ngokufaka i-Redispersible Polymer Powder (RDP), amandla okubopha, amandla okunamathela kanye nokumelana nomthelela kwemikhiqizo efana nokumbozwa kanye nezimbozo kuthuthukiswa kakhulu.

Ukumelana nesimo sezulu kanye nokumelana namakhemikhali: Ezinye izinhlobo ze-Redispersible Polymer Powder (RDP) zinokumelana okuhle kakhulu nemisebe ye-UV, amanzi kanye nokugqwala kwamakhemikhali.

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

Amandla okubopha athuthukisiwe Indima ebalulekile edlalwa yi-Redispersible Polymer Powder (RDP) ezintweni ezisekelwe kusimende ukuthuthukisa amandla ayo okubopha. Ukusebenzisana phakathi kwe-cement paste kanye nesistimu yokusabalalisa i-polymer kwenza izinhlayiya ze-polymer zinamathele ngempumelelo ebusweni bezinhlayiya ze-cement. Esakhiweni esincane se-cement ngemva kokuqina, ama-molecule e-polymer athuthukisa amandla okubopha phakathi kwezinhlayiya ze-cement ngesenzo sokuxhumana, ngaleyo ndlela kuthuthukiswe amandla okubopha kanye namandla okucindezela kwezinto ezisekelwe kusimende.

Ukuguquguquka okuthuthukisiwe kanye nokumelana nokuqhekeka I-Redispersible Polymer Powder (RDP) ingathuthukisa ukuguquguquka kwezinto ezisekelwe kusimende. Lapho izinto ezisekelwe kusimende zomiswa futhi ziqina, ama-molecule e-polymer ku-paste yesimende angakha ifilimu yokwandisa ukuqina kwezinto. Ngale ndlela, udaka lwesimende noma ukhonkolo alukwazi ukuqhekeka lapho lubhekene namandla angaphandle, okuthuthukisa ukumelana nokuqhekeka. Ngaphezu kwalokho, ukwakheka kwefilimu ye-polymer kungathuthukisa nokuzivumelanisa kwezinto ezisekelwe kusimende nendawo engaphandle (njengokushintsha komswakama, izinguquko zokushisa, njll.).

Ukulungisa ukusebenza kokwakha Ukwengezwa kwempuphu yeglue ephinde ihlakazeke kungathuthukisa nokusebenza kokwakhiwa kwezinto ezisekelwe kusimende. Isibonelo, ukufaka impuphu yeglue ephinde ihlakazeke ku-mortar exutshwe okomile kungathuthukisa kakhulu ukusebenza kwayo futhi kwenze inqubo yokwakha ibe lula. Ikakhulukazi ezinqubweni ezifana nokupenda odongeni kanye nokunamathisela amathayela, ukugeleza kwamanzi kanye nokugcinwa kwamanzi kwe-slurry kuyathuthuka, kugwenywe ukwehluleka kokubopha okubangelwa ukuhwamuka kwamanzi ngaphambi kwesikhathi.

Ukuthuthukisa ukumelana namanzi nokuqina Ukwakheka kwefilimu ye-polymer kungavimbela ngempumelelo ukungena kwamanzi, ngaleyo ndlela kuthuthukise ukumelana namanzi kwezinto. Kwezinye izindawo ezinomswakama noma ezimanzi, ukungezwa kwama-polymer kungalibazisa inqubo yokuguga kwezinto ezisekelwe kusimende futhi kuthuthukise ukusebenza kwazo kwesikhathi eside. Ngaphezu kwalokho, ukuba khona kwama-polymer kungathuthukisa ukumelana nesithwathwa kwezinto, ukumelana nokugqwala kwamakhemikhali, njll., futhi kwandise ukuqina kwesakhiwo sesakhiwo.

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

Udaka oluxubene nowomile Kudaka oluxubene nowomile, ukungezwa kwe-Redispersible Polymer Powder (RDP) kungathuthukisa ukunamathela, ukumelana nokuqhekeka kanye nokusebenza kokwakhiwa kodaka. Ikakhulukazi emikhakheni yesistimu yokuvikela udonga lwangaphandle, ukubopha amathayela, njll., ukwengeza inani elifanele le-Redispersible Polymer Powder (RDP) kufomula yodaka oluxubene nowomile kungathuthukisa kakhulu ukusebenza kahle kanye nekhwalithi yokwakha yomkhiqizo.

Izembozo zokwakha I-Redispersible Polymer Powder (RDP) ingathuthukisa ukunamathela, ukumelana namanzi, ukumelana nesimo sezulu, njll. kwezembozo zokwakha, ikakhulukazi ezimbozweni ezinezidingo zokusebenza okuphezulu njengezembozo zangaphandle zodonga kanye nezembozo zaphansi. Ukwengeza i-Redispersible Polymer Powder (RDP) kungathuthukisa ukwakheka kwayo kwefilimu kanye nokunamathela futhi kwandise impilo yenkonzo yezembozo.

Izinamathiseli Kweminye imikhiqizo ekhethekile yokunamathela, njengezinamathiseli zethayela, izinamathiseli ze-gypsum, njll., ukwengeza i-Redispersible Polymer Powder (RDP) kungathuthukisa kakhulu amandla okubopha futhi kuthuthukise ububanzi obufanele kanye nokusebenza kokwakhiwa kwe-glue.

Izinto ezingangeni manzi Ezintweni ezingangeni manzi, ukungezwa kwama-polymer kungakha ungqimba lwefilimu oluzinzile, kuvimbele ngempumelelo ukungena kwamanzi, futhi kuthuthukise ukusebenza okungangeni manzi. Ikakhulukazi kwezinye izindawo ezifunwa kakhulu (njengokungangeni manzi ebhodweni elingaphansi komhlaba, ukungangeni manzi ophahleni, njll.), ukusetshenziswa kwe-Redispersible Polymer Powder (RDP) kungathuthukisa kakhulu umphumela wokungangeni manzi.

Indlela yokusebenza kwe-I-RDP, ikakhulukazi ngenxa yokuguquguquka kwayo kanye nezici zokwakha ifilimu ye-polymer, inikeza imisebenzi eminingi ezintweni ezisekelwe kusimende, njengokuthuthukisa amandla okubopha, ukuthuthukisa ukuguquguquka, ukuthuthukisa ukumelana namanzi, kanye nokulungisa ukusebenza kokwakha. Ngaphezu kwalokho, ikhombisa nokusebenza okuhle kakhulu emikhakheni yodaka oluxutshwe okomile, izembozo zokwakha, izinamathiselo, izinto ezingangeni manzi, njll. Ngakho-ke, ukusetshenziswa kwe-Redispersible Polymer Powder (RDP) ezintweni zokwakha zesimanje kubaluleke kakhulu.
