Umsebenzi we-latex powder ehlakazeka kabusha:
1. Ii-latex powder ehlakazeka kabusha (Impushana enamathelayo eqinile Impushana yerabha emaphakathi Neutral latex powder）yakha ifilimu ngemva kokuhlakazwa futhi isebenza njengenamathela ukuze ithuthukise amandla ayo. 2. I-colloid evikelayo imuncwa uhlelo lodaka (ngeke ichithwe ngamanzi noma "ukuhlakazeka kwesibili" ngemva kokwakhiwa kwefilimu. 3. I-polymer resin eyenza ifilimu isakazwa kulo lonke uhlelo lodaka njengento yokuqinisa, ngaleyo ndlela ukwandisa ukuhlangana kodaka; i-latex powder ehlakazeka kabusha iyingcina yempushana eyenziwe ngokumisa i-lotion (i-polymer ephezulu) emva kokuxhumana nayo amanzi, le powder ingaphinde ihlakazwe ngokushesha ukuze yenze i-lotion, futhi inezici ezifanayo njenge-lotion yokuqala, okungukuthi, amanzi angenza ifilimu ngemva kokuhwamuka Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu nokunamathela okuphezulu kuma-substrates ahlukahlukene .
Umsebenzi weI-RDP: ukuthuthukisa ukumelana nomthelela, i-latex powder ephinda ihlakazeka iyinhlaka ye-thermoplastic. Ifilimu ethambile eboshwe phezu kwezinhlayiya zodaka, ezingabamba umthelela wamandla angaphandle, ziphumule ngaphandle kokulimala, ngaleyo ndlela zithuthukise ukumelana komthelela wodaka. Ukuthuthukisa ukumelana nokugqoka kanye nokuqina ngokungezai-latex powder ehlakazeka kabushaingakhuphula isibopho esiminyene phakathi kwezinhlayiya zodaka lukasimende namafilimu e-polymer. Ukuthuthukiswa kwamandla okunamathela ngokuhambisanayo kuthuthukisa ikhono ledaka ukuze limelane nengcindezi yokugunda, kunciphisa izinga lokuguga, kuthuthukisa ukumelana nokuguga, futhi kwandise impilo yesevisi yodaka. Ukuthuthukisa i-hydrophobicity nokunciphisa ukumuncwa kwamanzi, nokwengezai-latex powder ehlakazeka kabushaingathuthukisa i-microstructure yodaka lukasimende. I-polymer yayo yenza inethiwekhi engenakuhlehliswa enqubweni ye-cement hydration, ivala i-capillary kujeli kasimende, ivimbe ukungena kwamanzi, futhi ithuthukise ukungakwazi ukungena. Ukuthuthukisa amandla okubopha kanye nokuhlangana kwezinto ngokusetshenziswa kwei-latex powder ehlakazeka kabushaidlala indima ebalulekile ekuthuthukiseni amandla okubopha nokuhlangana kwezinto. Ngenxa yokungena kwezinhlayiya ze-polymer kuma-pores kanye nama-capillaries we-matrix ye-samente, ukuhlangana okuhle kwakhiwa ngemva kokumiswa kwe-hydration ne-cement. Amandla amahle kakhulu okubopha we-polymer resin ngokwawo athuthukisa ukunamathela kwemikhiqizo yodaka lukasimende kuma-substrates, ikakhulukazi usimende, i-inorganic binder, okhunini, imicu, i-PVC Ukuthuthukiswa kokunamathela okungalungile kwama-substrates e-organic njenge-EPS kunomthelela omkhulu. Ukuthuthukisa ukuzinza kweqhwa kuvimbela ngempumelelo ukuqhekeka kwezinto, kanyei-latex powder ehlakazeka kabushainomphumela wepulasitiki weresin yayo ye-thermoplastic, enganqoba umonakalo wokunwetshwa okushisayo nokufinyela okubangelwa ukushintsha kwezinga lokushisa ezintweni zodaka lukasimende. Ukunqoba izici ze-deformation enkulu ye-shrinkage eyomile kanye nokuqhekeka kalula kodaka oluhlanzekile lukasimende kungenza izinto eziguquguqukayo zibe nezimo, ngaleyo ndlela kuthuthukiswe ukuzinza kwesikhathi eside kwezinto. Thuthukisa ukugoba nokumelana nokuqinile. Ohlakeni oluqinile olwakhiwe yi-hydration yodaka lukasimende, i-membrane ye-polymer iyanwebeka futhi iyaguquguquka, idlala umsebenzi ofanayo njengesihlanganisi esinyakazayo phakathi kwezinhlayiya zodaka lukasimende. Ingakwazi ukumelana nemithwalo ephezulu yokuguquguquka, inciphise ukucindezeleka, futhi ithuthukise ukungezwani nokugoba.
Izinzuzo zei-latex powder ehlakazeka kabusha
Asikho isidingo sokugcina nokuthutha ngamanzi, ukunciphisa izindleko zokuhamba; Isikhathi eside sokugcina, i-anti-freezing, kulula ukuyigcina; Iphakheji incane ngosayizi, ilula ngesisindo, futhi kulula ukuyisebenzisa; Ingaxutshwa nesibophezelo esisekelwe emanzini ukuze kwakhiwe i-premix eguquliwe ye-resin yokwenziwa. Uma isetshenziswa, amanzi kuphela adinga ukungezwa, okungagcini nje ukugwema amaphutha ngesikhathi sokuxuba esizeni, kodwa futhi kuthuthukisa ukuphepha kokuphathwa komkhiqizo.
