Umsebenzi we-latex powder ehlakazeka kabusha:
1. I-latex powder ehlakazekayo yenza ifilimu futhi isebenze njenge-adhesive ukuze ithuthukise amandla ayo;
2. I-colloid evikelayo imuncwa uhlelo lodaka (ngeke lonakaliswe amanzi ngemva kokwakhiwa kwefilimu, noma "ukuhlakazeka kwesibili";
3. I-resin ye-polymer eyenza ifilimu isakazwa njengento yokuqinisa kulo lonke uhlelo lodaka, ngaleyo ndlela ikhulise ukuhlangana kodaka; I-emulsion powder ephinda ihlakazeka iwuhlobo lokunamathela okuyimpushana olwenziwa nge-lotion (i-polymer ephezulu yamangqamuzana) ngemva kokumiswa kwesifutho. Ngemva kokuthintana namanzi, le mpushana ingaphinde ihlakazwe ngokushesha ukuze yenze isithako, futhi inezakhiwo ezifanayo nelotion yokuqala, okungukuthi, amanzi angenza ifilimu ngemva kokuhwamuka. Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu nokunamathela okuphezulu kuma-substrates ahlukahlukene.
Indima ye-latex powder ehlakazeka kabusha:
Thuthukisa ukumelana nomthelela
I-latex powder ephinda ihlakazeka, okuyinhlaka 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
Ukwengeza impushana ye-latex ehlakazeka kabusha kungakhuphula ukubophana okuminyene 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
Ukwengeza i-latex powder ehlakazeka kabusha kungathuthukisa 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.
Thuthukisa amandla okubopha nokubumbana
I-latex powder ehlakazeka kabusha inomphumela obalulekile ekuthuthukiseni amandla okubopha nokuhlangana kwezinto. Ngenxa yokungena kwezinhlayiya ze-polymer kuma-pores kanye nama-capillaries we-matrix ye-cement, yakha ukubumbana okuhle ngemuva kokufakwa kwe-hydration nosimende. Ukunamathela okuhle kakhulu kwe-polymer resin ngokwayo kuthuthukisa ukunamathela kwemikhiqizo yodaka lukasimende kuma-substrates, ikakhulukazi ukunamathela okungalungile kwezibophezelo ze-inorganic ezifana usimende kuma-substrates e-organic njengokhuni, i-fiber, i-PVC, ne-EPS, Umphumela usobala.
Ukuthuthukisa ukuzinza kweqhwa nokuvimbela ngempumelelo ukuqhekeka kwempahla
Impushana ye-latex ehlakazeka kabusha kanye ne-thermoplastic resin yayo ingawunqoba umonakalo wokunwetshwa kwe-Thermal kodaka lukasimende okubangelwa umehluko wokushisa. 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 ze-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.
