I-RedisperibleTwetex Towder (RDP) ngumkhiqizo oguqula i-polymer emulsion ibe yimpuphu egeleza mahhala ngokusebenzisa ubuchwepheshe be-Spray Corring. Lapho i-powder ixutshwe namanzi, iphinda iphinde ithole i-latex futhi inezakhiwo ezifanayo ne-emulsion yasekuqaleni. Ngenxa yalokhu okuhlukile kwesici, i-latex ye-latex evuselelayo isetshenziswe kabanzi ezintweni zokwakha, ezinamathela, ukumboza kanye nezinye izinkambu.

Thuthukisa ukusebenza komkhiqizo okuvuselelwa kabusha kwe-latex powder kungathuthukisa kakhulu amandla ashukumisayo, amandla aguqukayo namandla e-bonding wezinto zokwenziwa kosimende. Lokhu kungenxa yokuthi i-latex powder ingakha i-polymer filfilimu eqhubekayo ngesikhathi senqubo ye-Cement Hydration, ithuthukise ubunzima nokuqina kokuqukethwe, ngaleyo ndlela kuthuthukise ukusebenza okuphelele. Isibonelo, ku-tile anamathela, engeza i-latex powder ingathuthukisa amandla abo okubopha futhi ivikele amathayili ukuthi awele.
Ukuvuselelwa okuqhekekile okuthuthukile nokungapheli izinto zokwakha, ukumelana nokuqhekeka kanye nokungapheli okungapheli kuyizinkomba zokusebenza ezibaluleke kakhulu. I-FATTEX evuselelayo ye-latex ingagcwalisa ngempumelelo ama-pores e-capillary ezintweni zokwakha ifilimu ye-polymer, ukunciphisa ukungena kwamanzi kanye nokwenza ngcono okungafanele. Ngasikhathi sinye, ukunwebeka kwefilimu ye-polymer nakho kunganciphisa noma kuvikele ukuthuthukiswa kwama-microcracks, ngaleyo ndlela kuthuthukise ukumelana nokuqhekeka. Ngakho-ke, i-latex powder isetshenziswa kabanzi ezinhlelweni zezinhlelo zodonga zangaphandle nezinto zokwakha phansi.
Ukusebenza okuthuthukile kokwakha: Kusukela i-watex ye-latex ye-latex evuselelayo kanye nokunamathela okuhle, kungathuthukisa ukugcotshwa kanye nokusebenza kwezinto zokwakha ngesikhathi senqubo yokwakha, okwenza kube lula ukusakaza nokusebenza. Ngaphezu kwalokho, i-latex powder ingaphinde futhi inwebe isikhathi sokuvula sezinto ezibonakalayo (okungukuthi, isikhathi esikade sihlala sisebenza ngesikhathi sokwakha), sithuthukise ukusebenza kahle kokwakha, futhi sinciphise imfucuza yezinto ezibonakalayo.
Ukuqina okuthuthukisiwe Ifilimu ye-polymer eyakhiwe kusuka ku-satex towx ye-latex inokumelana okuhle nokumelana nesimo sezulu. Kungavimbela ngempumelelo ithonya lemisebe ye-ultraviolet, i-acid kanye ne-alkali yokugqwala nezinye izici zezemvelo, ngaleyo ndlela unwebe impilo yenkonzo yezinto ezibonakalayo. Isibonelo, ukungeza i-tablex ye-latex kumapende odongeni engaphandle kungamelana ngempumelelo isimo sezulu kanye nokuguguleka kwemvula, futhi kugcinwe ubuhle nokusebenza kwendawo yokwakha.
Ukuvikelwa Kwezemvelo kanye nokusimama okuvuselelwa kabusha kwe-latex powder kuvame ukukhiqizwa ngokususelwa kwizinsizakusebenza ezingavuselelwa futhi akukhiphi izinto eziyingozi ngesikhathi sokusetshenziswa, okuhambisana nomkhuba wentuthuko wamanje wezinto zokwakha eziluhlaza. Ngaphezu kwalokho, ukusebenza kwayo okuhle kakhulu kuvumela ubukhulu kanye nenani lezinto zokwakha ukuze zincishiswe, zinciphise ukusetshenziswa kwezinsiza kanye nomthwalo wezemvelo.

Izindleko zokukhiqiza ziphezulu. Inqubo yokukhiqiza ye-Latex Powder evuselelayo iyinkimbinkimbi futhi idinga izinqubo eziningi ezifana ne-emulsion polymerization kanye nokomisa okufafaza. Ikakhulu kwinqubo yokumisa isifutho, inani elikhulu lamandla liyadliwa, ngakho-ke izindleko zokukhiqiza ziphezulu. Lokhu kuholele ekusetshenzisweni okulinganiselwe kwe-latex powder evuselelayo kwamanye amaphrojekthi wokwakha abiza kancane.
Uzwela ezimweni zezemvelo RedisperPressible Powder wate inweve ezimweni zezemvelo ezifana nokushisa kanye nomswakama. Ngesikhathi sokugcina nokuhamba, uma umswakama uphezulu kakhulu noma izinga lokushisa akulungile, i-fleatex powder ingaba ne-agglomerate noma yehluleke, ezothinta ukusebenza kwayo kokuthola kabusha kanye nomphumela wokugcina wohlelo lokusebenza. Ngakho-ke, inezidingo eziphezulu ezimweni zokugcina futhi idinga ukugcinwa endaweni eyomile nelipholile.
Ukulinganiselwa komsebenzi wokuhlakazeka yize i-latex ye-latex ye-latex engavuselelwa emanzini, umphumela wayo wokuhlakazeka usawohloka ngemuva kwalapho emulsion yasekuqaleni. Uma ikhwalithi lamanzi limpofu (njengamanzi anzima noma liqukethe ukungcola okuningi), kungathinta ukuhlakazwa kwe-latex powder futhi kuvikele ukusebenza kwalo ukuthi kungafinyeleleki ngokuphelele. Ngakho-ke, kuzinhlelo zokusebenza zangempela, kungahle kudingeke ukusebenzisa izithasiselo ezikhethekile noma ukulungisa ikhwalithi yamanzi ukuqinisekisa imiphumela emihle.
Ukuqwashisa ngemakethe kanye nokuphromotha kwesicelo njengento entsha ebonakalayo, i-redisperiblet latex powder inokuqwashisa okuphansi kwamanye amazwe asathuthuka noma izimakethe, futhi ukuphromotha kwawo kungaphansi kwemikhawulo ethile. Naphezu kokusebenza kwayo okuphakeme, ezinye izinkampani zokwakha zendabuko ziyemukelwa phansi ngenxa yezindleko eziphezulu zokukhiqiza kanye namanani. Imfundo yesikhathi nemakethe isadingeka ukushintsha lesi simo.
Ukuncintisana kusuka kwezinye izinto zokwakha ngokuthuthukiswa kwe-Material Science, izinto ezintsha ezintsha zivela njalo emakethe. Lezi zinto ezintsha zingakhombisa ukusebenza okuphezulu noma izindleko eziphansi kune-fteoder evuselelayo ye-latex kwezinye izici, zibeka izinselelo eziya kwisabelo semakethe se-latex powder. Ukuze uhlale uncintisane, izinkampani zokukhiqiza zidinga ukuthuthukisa ukusebenza komkhiqizo kanye nezindleko zokulawula.
Njengezinto ezisebenzayo ze-polymer, i-redisperible fteatex powder ikhombisile izinzuzo ezibalulekile emkhakheni wezinto zokwakha, ikakhulukazi ekwenzeni ngcono ukusebenza kwezinto ezibonakalayo, ngcono ukukheka kanye nokwenza ngcono ukuqina. Kodwa-ke, izindleko zayo eziphezulu zokukhiqiza, ukuzwela kwezimo zemvelo kanye nezinselelo zokuthengisa ngeke zinakwa. Esikhathini esizayo, ngokuthuthuka kobuchwepheshe kanye nokuvuthwa kwemakethe, kulindeleke ukuthi kusetshenziswe i-latex latex ye-latex emasimini amaningi, futhi ukusebenza kwayo nokusebenza nakho kuzophinde kulungiswe indima enkulu emkhakheni wezinto zokwakha .
