Indlela yokusebenza yePolymer Powder eDispersible (RDP)

I-Redispersible Polymer Powder (RDP)ngumgubo wepolymer wemolekyuli ephezulu, oqhele ukwenziwa kwi-polymer emulsion ngokumisa isitshizi. Inepropathi ye-dispersibility emanzini kwaye isetyenziswa ngokubanzi ekwakhiweni, iingubo, i-adhesives kunye nezinye iindawo. Indlela yokusebenza yeRedispersible Polymer Powder (RDP) iphunyezwa ikakhulu ngokuguqula izinto ezisekelwe kwisamente, ukuphucula amandla okubopha, kunye nokuphucula ukusebenza kolwakhiwo.

1. Ukwakhiwa okusisiseko kunye neempawu zePolymer Powder eDispersible (RDP)

Ukubunjwa okusisiseko kwe-Redispersible Polymer Powder (RDP) yi-polymer emulsion, ehlala i-polymerized ukusuka kwi-monomers ezifana ne-acrylate, i-ethylene, kunye ne-vinyl acetate. Ezi molekyuli zepolymer zenza amasuntswana amahle nge-emulsion polymerization. Ngexesha lokumisa inkqubo yokutshiza, amanzi ayasuswa ukuze enze i-amorphous powder. Ezi powders zinokuphinda zisasazwe emanzini ukuze zenze ii-polymer dispersions ezizinzileyo.

Iimpawu eziphambili zeRedispersible Polymer Powder (RDP) ziquka:

Ukunyibilika kwamanzi kunye ne-dispersibility: Inokusasazwa ngokukhawuleza emanzini ukwenza i-polymer colloid efanayo.

Iimpawu zomzimba eziphuculweyo: Ngokongeza i-Redispersible Polymer Powder (RDP), amandla okudibanisa, amandla okuqina kunye nokuchasana kwempembelelo yeemveliso ezifana neengubo kunye nodaka ziphuculwe kakhulu.

Ukuxhathisa imozulu kunye nokumelana neekhemikhali: Ezinye iintlobo zeRedispersible Polymer Powder (RDP) zikwazi ukumelana nemitha ye-UV, amanzi kunye nokudleka kweekhemikhali.

2. Indlela yokusebenza yeRedispersible Polymer Powder (RDP) kwimathiriyeli esekwe kwisamente

Ukuphuculwa kwamandla okudibanisa Indima ebalulekileyo edlalwa yi-Redispersible Polymer Powder (RDP) kwizinto ezisekelwe kwisamente kukuphucula amandla ayo okudibanisa. Ukusebenzisana phakathi kwe-cement paste kunye ne-polymer dispersion system yenza ukuba iinqununu ze-polymer zihambelane ngokufanelekileyo nomgangatho we-cement particles. Kwi-microstructure ye-cement emva kokuqina, iimolekyuli ze-polymer ziphucula amandla okudibanisa phakathi kweengqungquthela ze-samente ngokusebenzisa i-interfacial action, ngaloo ndlela kuphuculwe amandla okudibanisa kunye namandla oxinzelelo lwezixhobo ezisekelwe kwi-samente.

Ukuguquguquka okuphuculweyo kunye nokumelana nokuqhekeka i-Redispersible Polymer Powder (RDP) inokuphucula ukuguquguquka kwezinto ezisekelwe kwi-samente. Xa izinto ezisekelwe kwi-samente zomisiwe kwaye ziqiniswe, iimolekyuli ze-polymer kwi-sement paste zingenza ifilimu ukunyusa ukuqina kwezinto. Ngale ndlela, udaka lwesamente okanye ikhonkrithi ayiqhelekanga kwiintanda xa iphantsi kwamandla angaphandle, okuphucula ukuxhathisa ukuqhekeka. Ukongezelela, ukubunjwa kwefilimu ye-polymer kunokuphucula ukulungelelaniswa kwezinto ezisekelwe kwi-samente kwindawo yangaphandle (njengokutshintsha komswakama, utshintsho lweqondo lokushisa, njl.).

Ukulungelelanisa ukusebenza kolwakhiwo Ukongezwa kwe-glue powder edibeneyo kunokuphucula ukusebenza kokwakhiwa kwezinto ezisekelwe kwi-samente. Umzekelo, ukongeza umgubo weglu enokuphinda uhlawulwe kudaka oluxutyiweyo okomileyo kunokuphucula kakhulu ukusebenza kwayo kwaye yenze inkqubo yokwakha ibe mde. Ngokukodwa kwiinkqubo ezifana nepeyinti eludongeni kunye ne-tile yokunamathisela, i-fluidity kunye nokugcinwa kwamanzi kwi-slurry kuphuculwe, kugwenywe ukungaphumeleli kokubambisana okubangelwa ukukhuphuka kwamanzi kwangaphambi kwexesha.

Ukuphucula ukunganyangeki kwamanzi kunye nokuqina Ukwenziwa kwefilimu yepolymer kunokuthintela ngokufanelekileyo ukungena kwamanzi, ngaloo ndlela kuphuculwe ukuxhathisa kwamanzi kwizinto eziphathekayo. Kwezinye iindawo ezimanzi okanye ezimanzi, ukongezwa kweepolymers kunokulibazisa inkqubo yokuguga yezinto ezisekelwe kwi-samente kunye nokuphucula ukusebenza kwazo kwexesha elide. Ukongeza, ubukho beepolymers bunokuphucula ukuxhathisa kweqabaka, ukuchasana nokubola kweekhemikhali, njl., kunye nokwandisa ukuqina kwesakhiwo sokwakha.

3. Ukusetyenziswa kweRedispersible Polymer Powder (RDP) kwezinye iinkalo

Udaka oluxubeneyo olomileyo Kudaka oluxutyiweyo, ukongezwa kwe-Redispersible Polymer Powder (RDP) kunokunyusa ukunamathela, ukuxhathisa ukuqhekeka kunye nokusebenza kokwakhiwa kodaka. Ngokukodwa kwiinkalo zenkqubo yokufakelwa kwodonga lwangaphandle, ukudibanisa i-tile, njl., Ukongeza inani elifanelekileyo le-Redispersible Polymer Powder (RDP) kwifomula yodaka oluxubekileyo kunokuphucula kakhulu ukusebenza kunye nomgangatho wokwakhiwa kwemveliso.

Iingubo ze-Architectural Redispersible Polymer Powder (RDP) zinokuphucula ukubambelela, ukuxhathisa kwamanzi, ukuxhathisa kwemozulu, njl njl kwiingubo zokwakha, ngokukodwa kwiingubo ezineemfuno eziphezulu zokusebenza ezifana neengubo zangaphandle zodonga kunye neengubo zomgangatho. Ukongeza i-Redispersible Polymer Powder (RDP) inokuphucula ukubunjwa kwayo kwefilimu kunye nokunamathela kunye nokwandisa ubomi benkonzo yokugqoka.

I-Adhesives Kwezinye iimveliso ezinamathele ezikhethekileyo, ezifana ne-tile, i-gypsum adhesives, njl., Ukongeza i-Redispersible Polymer Powder (RDP) inokuphucula kakhulu amandla okudibanisa kunye nokuphucula umda osebenzayo kunye nokusebenza kokwakhiwa kwe-adhesive.

Izinto ezingangeni manzi Kwizinto ezingenamanzi, ukongezwa kweepolymers kunokwenza uluhlu lwefilimu oluzinzile, luthintele ngokufanelekileyo ukungena kwamanzi, kunye nokuphucula ukusebenza kwamanzi. Ngokukodwa kwezinye iindawo ezifunwa kakhulu (ezifana ne-basement waterproofing, i-roof waterproofing, njl.), Ukusetyenziswa kwe-Redispersible Polymer Powder (RDP) kunokuphucula kakhulu umphumo wokungena kwamanzi.

Indlela yokusebenza yeiRDP, ngokuyininzi ngokusebenzisa i-redispersibility yayo kunye neempawu zokwenza ifilimu ye-polymer, inikezela ngemisebenzi emininzi kwizinto ezisekelwe kwi-samente, ezifana nokuphucula amandla okudibanisa, ukuphucula ukuguquguquka, ukuphucula ukumelana kwamanzi, kunye nokulungelelanisa ukusebenza kokwakhiwa. Ukongezelela, ikwabonisa ukusebenza okugqwesileyo kwimihlaba yodaka oluxubeneyo oluxubeneyo, iingubo zezakhiwo, i-adhesives, izinto ezingenamanzi, njl. Ngoko ke, ukusetyenziswa kwe-Redispersible Polymer Powder (RDP) kwizinto zokwakha zanamhlanje kubaluleke kakhulu.
