I-Putty iyinto eyisisekelo esetshenziswa kabanzi ekwakheni amaphrojekthi okuhlobisa, futhi ikhwalithi yayo ithinta ngqo impilo yesevisi kanye nomphumela wokuhlobisa we-wall coating. Amandla okubopha kanye nokumelana namanzi kuyizinkomba ezibalulekile zokuhlola ukusebenza kwe-putty.Impushana ye-latex ehlakazeka kabusha, njenge-organic polymer modified material, idlala indima ebalulekile ekuthuthukiseni ukusebenza kwe-putty.
1. Indlela yokusebenza yempushana ye-latex ehlakazeka kabusha
Impushana ye-latex ehlakazeka kabusha iyimpushana eyakhiwe ngokumiswa kwesifutho se-polymer emulsion. Ingakwazi kabusha i-emulsify ukuze yakhe isistimu yokuhlakazeka kwe-polymer ezinzile ngemva kokuxhumana namanzi, edlala indima ekuthuthukiseni amandla okubopha kanye nokuguquguquka kwe-putty. Imisebenzi yayo eyinhloko ihlanganisa:
Ukuthuthukisa amandla okubopha: Impushana ye-latex ehlakazeka kabusha yakha ifilimu ye-polymer ngesikhathi senqubo yokumisa i-putty, futhi ihambisana nezinto ze-gelling ezingaphili ukuze kuthuthukiswe ikhono lokuhlanganisa ubuso.
Ukuthuthukisa ukumelana namanzi: I-Latex powder yakha inethiwekhi ye-hydrophobic esakhiweni se-putty, ukunciphisa ukungena kwamanzi nokuthuthukisa ukumelana kwamanzi.
Ukuthuthukisa ukuguquguquka: Kunganciphisa ukuqina kwe-putty, kuthuthukise ikhono lokuguga, futhi kunciphise ingozi yokuqhekeka.
2. Ucwaningo lokuhlola
Izinto zokuhlola
Izinto eziyisisekelo: i-putty powder esekwe kusimende
I-latex powder ehlakazeka kabusha: i-ethylene-vinyl acetate (EVA) i-copolymer latex powder
Ezinye izithasiselo: i-thickener, i-ejenti yokugcina amanzi, i-filler, njll.
Indlela yokuhlola
Ama-putty anemithamo ehlukene ye-latex powder ehlakazeka kabusha (0%, 2%, 5%, 8%, 10%) alungiswa ngokulandelana, futhi amandla awo okubopha kanye nokumelana namanzi kwahlolwa. Amandla okubopha anqunywa ukuhlolwa kokukhipha, futhi ukuhlolwa kokumelana namanzi kwahlolwa izinga lokugcinwa kwamandla ngemva kokucwiliswa emanzini amahora angu-24.
3. Imiphumela kanye nengxoxo
Umthelela wempushana ye-latex ehlakazeka kabusha emandleni okubopha
Imiphumela yokuhlolwa ikhombisa ukuthi ngokwenyuka komthamo we-RDP, amandla okubopha i-putty akhombisa umkhuba wokunyuka kuqala bese uzinza.
Lapho umthamo we-RDP ukhuphuka usuka ku-0% uye ku-5%, amandla okubopha we-putty athuthukiswa kakhulu, ngoba ifilimu ye-polymer eyakhiwe yi-RDP ithuthukisa amandla okubopha phakathi kwezinto eziyisisekelo kanye ne-putty.
Qhubeka nokwandisa i-RDP ibe ngaphezu kuka-8%, ukukhula kwamandla okubopha kuvame ukuba flat, futhi ngisho kuncipha kancane ku-10%, okungase kube ngenxa yokuthi i-RDP eyeqile izothinta isakhiwo esiqinile se-putty futhi sinciphise amandla esixhumi esibonakalayo.
Umthelela wempushana ye-latex ehlakazeka kabusha ekumelana namanzi
Imiphumela yokuhlolwa kokumelana namanzi ikhombisa ukuthi inani le-RDP linomthelela omkhulu ekungangeni kwamanzi kwe-putty.
Amandla okubopha i-putty ngaphandle kwe-RDP ehle kakhulu ngemva kokucwiliswa emanzini, okubonisa ukungazweli kahle kwamanzi.
Ukwengezwa kwenani elifanele le-RDP (5% -8%) kwenza i-putty ibe ukwakheka kwenhlanganisela ye-organic-inorganic eminyene, kuthuthukisa ukumelana namanzi, futhi kuthuthukisa kakhulu izinga lokugcinwa kwamandla ngemva kwamahora angu-24 wokucwiliswa.
Kodwa-ke, lapho okuqukethwe kwe-RDP kudlula u-8%, ukuthuthukiswa kokungazweli kwamanzi kuncipha, okungahle kube ngenxa yokuthi izingxenye eziningi eziphilayo zinciphisa amandla e-anti-hydrolysis e-putty.
Iziphetho ezilandelayo zingafinyelelwa ocwaningweni lokuhlola:
Inani elifanele lei-latex powder ehlakazeka kabusha(5% -8%) ingathuthukisa kakhulu amandla okubopha kanye nokumelana namanzi kwe-putty.
Ukusetshenziswa ngokweqile kwe-RDP (>8%) kungase kuthinte ukwakheka okuqinile kwe-putty, okuholela ekwehleni noma ngisho nokuncipha ekuthuthukisweni kwamandla ebhondi kanye nokumelana namanzi.
Umthamo ophelele udinga ukuthuthukiswa ngokuya ngesimo esithile sohlelo lokusebenza lwe-putty ukuze kuzuzwe ibhalansi engcono kakhulu phakathi kokusebenza nezindleko.
