I-Putty iyinto eyisisekelo esetshenziswa kabanzi kumaphrojekthi okuhlobisa izakhiwo, futhi ikhwalithi yayo ithinta ngqo impilo yesevisi kanye nomphumela wokuhlobisa wengubo yodonga. Amandla okubopha kanye nokumelana namanzi kuyizinkomba ezibalulekile zokuhlola ukusebenza kwe-putty.Impuphu ye-latex ephinde ihlakazeke, njengezinto eziguqulwe yi-polymer yemvelo, idlala indima ebalulekile ekuthuthukiseni ukusebenza kwe-putty.
1. Indlela yokusebenza kwempuphu ye-latex ephinde ihlakazeke
Impuphu ye-latex ephinde ihlakazeke iyimpuphu eyakhiwe ngokufuthwa kwe-polymer emulsion. Ingaphinda ihlanganiswe ukuze yakhe uhlelo oluzinzile lokusabalala kwe-polymer ngemva kokuthinta amanzi, oludlala indima ekukhuliseni amandla okubopha kanye nokuguquguquka kwe-putty. Imisebenzi yayo eyinhloko ihlanganisa:
Ukuthuthukisa amandla okubopha: Impuphu ye-latex ephinde ihlakazeke yakha ifilimu ye-polymer ngesikhathi senqubo yokomisa i-putty, futhi isebenzisana nezinto ze-gelling ezingaphili ukuze kuthuthukiswe ikhono lokubopha phakathi kwe-interfacial.
Ukuthuthukisa ukumelana namanzi: Impuphu ye-latex yakha inethiwekhi engathandi amanzi esakhiweni se-putty, inciphisa ukungena kwamanzi futhi ithuthukise ukumelana namanzi.
Ukuthuthukisa ukuguquguquka: Kunganciphisa ukuphuka kwe-putty, kuthuthukise ikhono lokuguquguquka, futhi kunciphise ingozi yokuqhekeka.
2. Ucwaningo lokuhlola
Izinto zokuhlola
Izinto eziyisisekelo: i-putty powder esekwe kusimende
Impuphu ye-latex ephinde ihlakazeke: i-ethylene-vinyl acetate (EVA) copolymer latex powder
Ezinye izithasiselo: isithambisi, i-ejenti yokugcina amanzi, isigcwalisi, njll.
Indlela yokuhlola
Ama-putties anezilinganiso ezahlukene zempuphu ye-latex ephinde ihlakazeke (0%, 2%, 5%, 8%, 10%) alungiswa ngokulandelana, futhi amandla awo okubopha kanye nokumelana namanzi ahlolwe. Amandla okubopha anqunywa ngokuhlolwa kokukhipha, kanti ukuhlolwa kokumelana namanzi kwahlolwa ngesilinganiso sokugcina amandla ngemva kokucwiliswa emanzini amahora angama-24.
3. Imiphumela kanye nengxoxo
Umphumela wempuphu ye-latex ephinde ihlakazeke emandleni okubopha
Imiphumela yokuhlolwa ikhombisa ukuthi ngokwanda komthamo we-RDP, amandla okubopha e-putty abonisa ukuthambekela kokukhula kuqala bese kuba ukuzinza.
Uma umthamo we-RDP ukhuphuka kusuka ku-0% kuya ku-5%, amandla okubopha e-putty athuthukiswa kakhulu, ngoba ifilimu ye-polymer eyakhiwe yi-RDP ithuthukisa amandla okubopha phakathi kwezinto eziyisisekelo kanye ne-putty.
Qhubeka ukwandisa i-RDP ibe ngaphezu kuka-8%, ukukhula kwamandla okubopha kuvame ukuba yisicaba, futhi kwehla kancane ku-10%, okungenzeka ukuthi kungenxa yokuthi i-RDP eyeqile izothinta isakhiwo esiqinile se-putty futhi yehlise amandla esibonakalayo.
Umphumela wempuphu ye-latex ephinde ihlakazeke ekumelaneni namanzi
Imiphumela yokuhlolwa kokumelana namanzi ikhombisa ukuthi inani le-RDP linomthelela omkhulu ekumelaneni namanzi kwe-putty.
Amandla okubopha e-putty ngaphandle kwe-RDP anciphe kakhulu ngemva kokucwiliswa emanzini, okubonisa ukumelana kwamanzi okungekuhle.
Ukwengezwa kwenani elifanele le-RDP (5%-8%) kwenza i-putty yakhe isakhiwo esihlanganisiwe esiqinile se-organic-inorganic, kuthuthukisa ukumelana namanzi, futhi kuthuthukisa kakhulu izinga lokugcina amandla ngemva kwamahora angu-24 okucwiliswa.
Kodwa-ke, lapho okuqukethwe yi-RDP kudlula u-8%, ukuthuthuka kokumelana namanzi kuyancipha, okungaba ngenxa yokuthi izingxenye eziningi kakhulu zezinto eziphilayo zinciphisa ikhono lokulwa ne-hydrolysis le-putty.
Iziphetho ezilandelayo zingatholakala ocwaningweni lokuhlola:
Inani elifanele lei-latex powder ephinde ihlakazeke(5%-8%) ingathuthukisa kakhulu amandla okubopha kanye nokumelana namanzi kwe-putty.
Ukusetshenziswa ngokweqile kwe-RDP (>8%) kungathinta isakhiwo esiqinile se-putty, okuholela ekunciphiseni noma ekunciphiseni ukuthuthuka kwamandla okubopha kanye nokumelana namanzi.
Isilinganiso esifanele sidinga ukulungiswa ngokwesimo esithile sokusetshenziswa kwe-putty ukuze kufezwe ibhalansi engcono kakhulu phakathi kokusebenza kanye nezindleko.
