Umxholo womlotha we-polymer powders (RDP) yiparameter ebalulekileyo echaphazela kakhulu ukusebenza kwabo kwizicelo ezahlukeneyo, ngakumbi kwishishini lokwakha.Ngelixa umntu enokucinga ukuba umxholo wothuthu ophantsi ungcono, kubalulekile ukuqonda indima yothuthu oludlala kwiipropati kunye nokusebenza kwe-RDP.
Funda malunga neRedispersible Polymer Powders (RDP):
I-RDP yipolymer eyenziwe ngumgubo eyenza ifilimu efana nepolima yokuqala xa ixutywe namanzi.Isetyenziswa ngokubanzi kwizicelo zokwakha ezifana nodaka kunye nekhonkrithi ukunyusa iipropati zabo.I-RDP ithathwa kwi-emulsion polymerization yeendidi ze-monomers, kuquka i-vinyl acetate, i-ethylene kunye ne-acrylates.
Intsingiselo yesiqulatho sothuthu:
Umxholo wothuthu ubhekisa kwintsalela ye-inorganic eshiywe emva kokuba isampulu itshisiwe.Kwi-RDP, umxholo wothuthu udla ngokunxulumana nobukho beeminerali ezishiyekileyo kunye nezinye izinto ezingaphiliyo kwipolymer.Ukumiselwa komxholo womlotha kubalulekile njengoko kuchaphazela ukusebenza kwepolymer ngokubhekiselele kwi-dispersion, ukubunjwa kwefilimu kunye nomgangatho jikelele.
Umxholo wothuthu olusezantsi: iinzuzo
Phucula ukusasazwa:
Umxholo wothuthu olusezantsi unxulunyaniswa ne-dispersibility engcono emanzini.Oku kubalulekile kwi-RDP njengoko kufuneka yenze usasazo oluzinzileyo xa luxutywe namanzi ukuqinisekisa ukuba usasazo olulinganayo phakathi kodaka okanye umxube wekhonkrithi.
Yandisa ukwenziwa kwefilimu:
Umxholo ongezantsi womlotha unceda ukwenza ifilimu efanayo kunye neguquguqukayo.Oku kunceda ukuphucula ukunamathela kunye nokudibanisa kwezinto zokugqibela zokwakha.
Nciphisa imfuno yamanzi:
Ii-RDPs ezinothuthu oluphantsi zinokufuna amanzi amancinci ukuze zisasazwe kwakhona.Oku kunenzuzo kwimixube apho isiqulatho samanzi kufuneka sincitshiswe ukufezekisa izinto eziphathekayo ezinqwenelekayo.
Iipropati zoomatshini eziphuculweyo:
Isiqulatho sothuthu esisezantsi sinokuba negalelo kwiipropathi ezingcono zomatshini wesixhobo sokugqibela sokwakha.Oku kubandakanya ukuphuculwa kwamandla okuqina, ukuguquguquka kunye nokuqina.
Nciphisa imozulu:
I-efflorescence, ukubekelwa kweetyuwa ezinyibilikayo kumphezulu wento, inokuncitshiswa sisiqulatho sothuthu esisezantsi.Oku kubalulekile ekugcineni ubuhle kunye nokunyaniseka kwesakhiwo semathiriyeli yokwakha.
Umxholo wothuthu oluphezulu: iingqwalasela
Ukuqwalaselwa kweendleko:
Iinkqubo zokuvelisa ezifikelela kwiziqulatho ezisezantsi zothuthu zinokuba neendleko eziphezulu zemveliso.Ngoko ke, kukho ukurhweba phakathi kokuphumeza umsebenzi ofunekayo kunye nokusebenza kakuhle kweendleko.
Iinkcukacha zesicelo:
Ngokuxhomekeke kwisicelo, ezinye iifomula zinokunyamezela iziqulatho zothuthu eziphezulu ngaphandle kokuchaphazela ukusebenza.Kule meko, uhlalutyo lweendleko-inzuzo lubalulekile ekunqumeni umxholo wothuthu owamkelekileyo.
Ukuthotyelwa koMgaqo:
Imimandla eyahlukeneyo ingaba nemimiselo ethile okanye imigangatho yobuninzi obuvumelekileyo bomlotha wezinto zokwakha.Ukubambelela kule migangatho kubalulekile ekwamkelweni kweemarike.
Ukuphucula nokulawula umgangatho:
Ukufumana ibhalansi elungileyo phakathi kweenzuzo kunye nokunciphisa okunokubakho komxholo wothuthu oluphantsi, abavelisi badla ngokubandakanyeka ekuphuculeni ngokungqongqo kunye neenkqubo zokulawula umgangatho.Ezi nkqubo zibandakanya ukulungelelaniswa kweemeko zepolymerization, kusetyenziswa izinto ezikrwada ezikumgangatho ophezulu, kunye nokusetyenziswa kobuchule bokucoca obusebenzayo.
ukuququmbela:
Ngelixa isiqulatho sothuthu esisezantsi kwi-RDP sibonelela ngeenzuzo ezininzi, iimfuno ezithile zesicelo esicetywayo kufuneka siqwalaselwe.Isiqulatho sothuthu sinokwahluka ngokuxhomekeke kwizinto ezifana neempawu ezifunekayo zesixhobo sokwakha, ukuqwalaselwa kweendleko kunye neemfuno zolawulo.Abavelisi kufuneka balungelelanise ngononophelo ezi zinto ukuze bavelise iRDP ekumgangatho ophezulu ehlangabezana neemfuno ezahlukeneyo zoshishino lokwakha.Ukuqonda ngokupheleleyo intsebenziswano phakathi kothuthu kunye neepropati zeRDP kubalulekile ekuqinisekiseni impumelelo yeprojekthi yokwakha kunye nobude bezinto ezisetyenziswayo.
