(1 Isingeniso
I-Redispersible Polymer Powder (RDP) i-polymer powder eguquliwe engaphinde ihlakazwe ibe yi-emulsion lapho ivuliwe emanzini. Yenziwe ngokumiswa kwesifutho futhi ihlanganiswa kakhulu nezinto eziyisisekelo ezifana ne-ethylene vinyl acetate (VAE), i-acrylate copolymer ne-styrene-butadiene. Embonini yezokwakha, i-RDP isibe isithasiselo esibalulekile futhi isetshenziswa kabanzi ezintweni ezisekelwe kusimende kanye ne-gypsum, izinsimbi ezomile, izinamathelisi zamathayili e-ceramic, izitezi ezizilinganisa, izinhlelo zokuvala udonga zangaphandle kanye neminye imikhakha.
(2) Thuthukisa ukusebenza kwesibopho
1. Thuthukisa ukunamathela phakathi kwama-substrates
Uma i-RDP isetshenziswa ezintweni ezisekelwe kusimende kanye ne-gypsum, ingathuthukisa kakhulu izakhiwo zokubopha zezinto. Lokhu kungenxa yokuthi i-RDP ingaphinde ihlakazeke ukuze yakhe i-emulsion ngesikhathi sokusabela kwe-hydration, ngaleyo ndlela yakhe ifilimu ye-polymer efanayo ebusweni be-substrate. Le filimu ingangena kuma-pores kanye nemifantu emincane ye-substrate futhi ithuthukise ukukhiya komshini phakathi kwama-substrates, ngaleyo ndlela ithuthukise amandla okubopha.
2. Thuthukisa amandla okubopha phakathi kwezingqimba
Kuzinhlelo zokusebenza ezinezendlalelo eziningi, ezifana nezitezi ezizilinganisa ngokwazo, izendlalelo zikakhonkolo, njll., i-RDP ingathuthukisa ngokuphawulekayo amandla okuhlanganisa ama-inter-layer futhi igweme ukuxebuka phakathi kwezingqimba. Ngokwenza uhlaka oluqinile lwenethiwekhi ye-polymer, iqinisekisa ukusebenza okungcono kokubopha phakathi kwezendlalelo ezihlukene futhi ihlinzeka ngesakhiwo sonke esizinzile.
(3) Thuthukisa ukumelana nokuqhekeka nokuguquguquka kwezinto
1. Yehlisa ukwenzeka kwemifantu
Phakathi nenqubo yokuqina, izinto ezisekelwe kusimende zijwayele ukuqhekeka ngenxa yokuhwamuka kwamanzi kanye nokushintsha kwezinga lokushisa. Ukwengezwa kwe-RDP kunganciphisa ngempumelelo ukwenzeka kwemifantu. Ifilimu ye-polymer eyakhiwe yi-RDP ngemva kokuqina ingadonsa futhi ikhulule ukucindezeleka kwezinto futhi inciphise ukuvela kwemifantu. Lokhu kubaluleke kakhulu ezinhlelweni zokuvikela udonga lwangaphandle kanye nezinamatheliso zamathayili, njengoba lezi zinhlelo zokusebenza zibhekana nokushintsha kwezinga lokushisa nokuswakama okuhlukile.
2. Thuthukisa ukuguquguquka kwezinto
Izinto zokwakha zidinga ukuba nezinga elithile lokuguquguquka ngesikhathi sokwakhiwa futhi zisetshenziswe ukuze zivumelane nokuguqulwa okuncane kwezinto eziyisisekelo ngaphandle kokuqhekeka. I-RDP ingathuthukisa kakhulu ukuguquguquka kwezinto, ivumele okokusebenza ukuthi kube nekhono elithile lokuguquguquka ngaphansi kwesenzo samandla angaphandle ngaphandle kokudala umonakalo, ngaleyo ndlela kunwebe impilo yesevisi yezinto.
(4) Thuthukisa ukusebenza komsebenzi wokwakha
1. Thuthukisa ukwenza kube lula ukwakha
I-RDP ingathuthukisa kakhulu ukusebenza kokwakhiwa kodaka olomile. Kungakhuphula uketshezi nokusebenza kodaka, kwenze kube lula ukuxutshwa, ukusabalala kanye nezinga. Lokhu kubaluleke kakhulu kuma-adhesive ama-tile namajazi we-plaster adinga ukufakwa okubucayi.
2. Nweba amahora okuvula
Phakathi nenqubo yokwakha, isikhathi esivulekile sezinto ezibonakalayo (okungukuthi, isikhathi impahla esesimweni esisebenzayo) sibaluleke kakhulu. I-RDP inganweba isikhathi sokuvula ngokulungisa ukugcinwa komswakama wodaka, inikeze abasebenzi bokwakha isikhathi esengeziwe sokwenza izinguquko nokulungisa, kanye nokuthuthukisa ukusebenza kahle kokwakha.
(5) Thuthukisa ukuqina nokumelana nokugqwala kwamakhemikhali
1. Thuthukisa ukumelana namanzi
I-RDP ingathuthukisa kakhulu ukumelana kwamanzi nezinto ezisekelwe kusimende. Yakha ifilimu ye-polymer eminyene ebusweni bempahla ukunciphisa ukungena nokumuncwa komswakama futhi igweme ukuwohloka kokusebenza kwempahla okubangelwa umswakama. Lesi sakhiwo sibaluleke kakhulu ezintweni ezingaphansi kokuchayeka isikhathi eside kumswakama.
2. Thuthukisa ukumelana nokugqwala kwamakhemikhali
Izinto zokwakha zizovezwa kumakhemikhali ahlukahlukene ngesikhathi sokusetshenziswa, njengama-asidi, ama-alkali, usawoti, njll. I-RDP ingathuthukisa ukumelana kwempahla ekugqwaleni kwamakhemikhali futhi inciphise ukugqwala kwezinto ngezinto zamakhemikhali, ngaleyo ndlela yandise impilo yesevisi yezinto. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza ezifana nezinhlelo zokuvikela udonga zangaphandle kanye nezinto zokubeka phansi ezimbonini.
(6) Ubungane bemvelo
1. Yehlisa umthelela kwezemvelo
Njengempahla ehambisana nemvelo, inqubo yokukhiqiza ye-RDP ihambisana nemvelo futhi inganciphisa ukungcoliswa kwemvelo. Ngaphezu kwalokho, kunganciphisa ukuqhekeka nokulimala kwezinto ngesikhathi sokusetshenziswa, ngaleyo ndlela kunciphise imvamisa yokulungisa nokushintshwa, futhi kunciphise ngokungaqondile ukusetshenziswa kwezinto ezibonakalayo kanye nomthwalo wemvelo.
2. Yehlisa ukukhishwa kwe-volatile organic compound (VOC).
Njengomkhiqizo ongena-solvent, i-RDP inganciphisa kakhulu ukukhishwa kwe-volatile organic compounds (VOC) ezintweni zokwakha, ezingafinyeleli kuphela izidingo zokuvikela imvelo, kodwa futhi kuthuthukisa izinga lomoya lendawo yokwakha.
(7) Izinzuzo zezomnotho
1. Yehlisa izindleko zizonke
Nakuba i-RDP ngokwayo ingase yengeze inani elithile lezindleko zempahla, ngokuthuthukisa ukusebenza nokuqina kwempahla, izindleko zokulungisa nokushintshwa kwezinto zingancishiswa, ezinganciphisa izindleko eziphelele ngokuhamba kwesikhathi. I-RDP ingenza izinto zokwakha zibe nokusebenza kahle okuphezulu nempilo yesevisi ende, inciphise ukwakhiwa kwesibili kanye nokumoshakala kwezinto ezibonakalayo, ngaleyo ndlela ilethe izinzuzo zezomnotho.
2. Thuthukisa ikhwalithi yokwakha
Ukusebenzisa i-RDP kungathuthukisa ikhwalithi isiyonke yesakhiwo futhi kunciphise izindleko zokuphinda zisetshenzwe kanye nokunakekelwa okubangelwa izinkinga zekhwalithi yezinto ezibonakalayo. Konjiniyela kanye nezinhlangano zokwakha, izinto zokwakha zekhwalithi ephezulu zisho izikhalazo zekhwalithi ezimbalwa kanye nezinkinga zokunakekelwa, ngaleyo ndlela kuthuthukisa ukwethembeka nokuncintisana kwemakethe kwephrojekthi.
(8) Izibonelo zokusetshenziswa
1. I-adhesive ye-tile
Ukwengeza i-RDP ku-adhesive tile kungathuthukisa amandla okubopha phakathi kwethayela ne-substrate, kuthuthukise ukusebenza kokunamathela kokunamathelayo, futhi kujwayelane nama-substrates ahlukene nezimo zokwakha.
2. Uhlelo lwangaphandle lokuvikela udonga
Ezinhlelweni zokufakwa odongeni zangaphandle, i-RDP ingathuthukisa ukunamathela phakathi kongqimba olufakwayo kanye nesendlalelo sokuhlobisa, ithuthukise ukuzinza okuphelele kwesistimu, futhi ithuthukise ukumelana nokuqhekeka nokuqina kwesistimu.
3. Ukuzilinganisa phansi
Ukusetshenziswa kwe-RDP ezitezi ezizilinganisayo kungathuthukisa ukucaba nokumelana nokugqokwa kwephansi, kuthuthukise ukusebenza kahle kokwakhiwa, futhi kujwayelane nezimo zomhlaba eziyinkimbinkimbi.
I-latex powder ehlakazeka kabusha inezinzuzo ezibalulekile ezinhlelweni zokwakha. Ingathuthukisa izakhiwo zokubopha izinto, ithuthukise ukumelana nokuqhekeka nokuguquguquka, ithuthukise ukusebenza kokwakhiwa, ithuthukise ukuqina nokumelana nokugqwala kwamakhemikhali, futhi inezinzuzo zemvelo nezomnotho. Ezimpahleni zokwakha zesimanje, ukusetshenziswa kwe-RDP sekungenye yezinto ezibalulekile zokuthuthukisa ukusebenza kwempahla kanye nekhwalithi yokwakha. Ngokuthuthuka kobuchwepheshe kanye nokwanda okuqhubekayo kwezicelo, i-RDP izokhombisa inani layo eliyingqayizivele kanye nezinzuzo emikhakheni eminingi yokwakha.
