Ezinhlelweni zesimanje zezinto zokwakha, i-putty powder isebenza njengento ebalulekile yokulinganisa udonga kanye nokuqedela ubuso. Ukusebenza kwayo kuthinta ngqo ikhwalithi nokuqina kwezembozo noma ukuqeda okulandelayo. Ukumelana namanzi kuyisibonakaliso esibalulekile sekhwalithi ye-putty. I-putty yendabuko ivame ukusekelwe ezibophezelweni ezingaphili (njenge-lime lime, umlotha ophindwe kabili, kanye nesamente). Kodwa-ke, ngenxa yokungaqini kwayo kanye nokunamathela okubi, ihlakazeka kalula lapho ithinta amanzi, okwenza kube nzima ukuhlangabezana nezidingo zokusetshenziswa isikhathi eside ezindongeni zangaphakathi nezangaphandle. Ngokusebenzisai-polymer powder ephinde ihlakazeke (RDP), ukusebenza kwe-putty iyonke, ikakhulukazi ukumelana kwayo namanzi, kuthuthukiswe kakhulu.
1. Izakhiwo Eziyisisekelo ze-RDP
I-RDP iyi-emulsion eyomisiwe ngokufuthwa eguqulwa ibe yimpuphu eqinile ephinde ihlakazeke. Lapho ihlangana namanzi, iphinda ihlanganise futhi ibuyisele izakhiwo zokuqala ze-emulsion. Yakhiwe ngokuyinhloko nge-resin ye-polymer enesisindo sama-molecule amaningi, i-colloid evikelayo, kanye nezithasiselo. Ngenxa yezakhiwo zayo ezinhle kakhulu zokwakha ifilimu, ukuguquguquka, kanye nokunamathela, isetshenziswa kabanzi ezintweni zokwakha ezifana nodaka oluxutshwe nowomile, i-adhesive yethayela, kanye ne-putty powder.
2. Izizathu Zokumelana Kabi Namanzi KaPutty
Izingxenye ezingezona ezingokwemvelo ziyaphuka: I-putty ye-lime-lime noma i-putty yesamente evamile iba nemifantu ngemva kokumanzisa amanzi, okuholela esakhiweni esixegayo kanye nokungena kwamanzi kalula.
Ukunamathela Okwanele: Ukuhlangana kobuso phakathi kwe-putty nodonga oluyisisekelo kanye noqweqwe kubuthakathaka, okwenza kube lula ukukhukhumala nokuwa ezindaweni ezinomswakama noma ezingaphansi kwamanzi.
Ukubhoboka Okuphezulu: Impuphu ye-putty yendabuko inobunzima obuphansi besakhiwo kanye nama-capillary amaningi, okwenza kube lula ukuthi amanzi angene futhi abangele ukubola.
Ngakho-ke, ukuthembela kuphela ezibophezelweni ezingaphili ngeke kuqinisekise ukumelana kwamanzi kwesikhathi eside kwe-putty. Ukuguqulwa ngama-polymers afana ne-RDP kuyadingeka.
3. Indlela Yokuthuthukisa Ukumelana Namanzi Kwe-Putty Kwe-RDP
3.1. Umphumela Wokwenza Amafilimu
Ngemva kokuba i-RDP ihlakazeke emanzini ku-putty, yakha ifilimu ye-polymer eqhubekayo ngesikhathi senqubo yokuqina, imboze ngokulinganayo izinhlayiya ezingaphili. Lokhu kunciphisa kakhulu ukugoba kwangaphakathi kwe-putty, ngaleyo ndlela kunciphisa ukungena kwamanzi.
3.2. Ukunamathela Okuthuthukisiwe
Ifilimu ye-polymer ingena kuma-micropores esendlalelo sesisekelo, idale umphumela ophindwe kabili "wokubopha okunamathelayo ngokomzimba + kwamakhemikhali". Lokhu kuqinisa ukunamathelana phakathi kwe-putty kanye ne-substrate, kuyivimbela ukuthi iwe ngisho nasezindaweni ezinomswakama.
3.3. Ukuzivumelanisa Okuthuthukisiwe Nokumelana Nokuqhekeka
I-putty ivame ukuqhekeka ngenxa yokuncipha noma ukushintshashintsha kwezinga lokushisa nomswakama, futhi imifantu iba yindlela enkulu yokungena komswakama. I-RDP inikeza ukuguquguquka okuhle kakhulu kanye nokwandiswa kwe-putty, iqeda ukucindezeleka futhi inciphise ukwakheka kwemifantu, ithuthukise ngokungaqondile ukumelana namanzi.
3.4. Amandla Okulwa Nokupholisha Okuthuthukisiwe
I-putty ye-lime-lime yendabuko ilula ukuyisusa uma ifakwa emanzini. Kodwa-ke, uhlaka lwe-polymer olwakhiwe yi-RDP ku-putty luthuthukisa kakhulu ukuqina kwesakhiwo salo, luvimbela ukuguguleka kwe-powder okubangelwa ukuguguleka kwamanzi.
4. Imiphumela ye-RDP ku-Putty Engangeni Manzi
Ukumelana Namanzi Okuthuthukisiwe Kakhulu: Ukuhlolwa kubonise ukuthi i-putty equkethe inani elifanele le-RDP igcina ubuqotho bomphezulu ngemva kwamahora angu-24 okucwiliswa emanzini, ngaphandle kokuqhekeka noma ukuxebuka okubonakalayo. Ukusebenza Okuthuthukisiwe: I-RDP inikeza ukuthambisa okukhulu nokugcinwa kwamanzi ku-putty, okuvumela ukusetshenziswa okubushelelezi nokusetshenziswa okulula.
Ukusetshenziswa Okubanzi: I-putty efakwe i-RDP ayifanele nje kuphela ezindaweni ezomile zangaphakathi kodwa futhi nasezindaweni ezinomswakama njengekhishi, izindlu zangasese, kanye nezindlu ezingaphansi komhlaba, ngisho ne-putty yangaphandle yodonga.
Impilo Yesevisi Ende: I-putty engangeni manzi imelana ngempumelelo nokuguguleka komswakama kwesikhathi eside, yandisa ukuqina kwezinhlelo zokuqeda udonga futhi inciphise izindleko zokulungisa ezilandelayo.
5. Izincomo ze-RDP Dosage kanye ne-Ratio
Isilinganiso se-RDP esinconywayo kumafomula e-putty ngokuvamile singu-3%-5% (ngokusekelwe esisindweni sempuphu ye-putty). Inani elithile kufanele lilungiswe ngokusekelwe ohlotsheni lwe-putty, izici ze-substrate, kanye nendawo yokusetshenziswa:
I-putty evamile yangaphakathi: Cishe u-3% wanele ukuhlangabezana nezidingo eziyisisekelo zokumelana namanzi;
I-putty yasekhishini neyasendlini yokugezela: 4%-5% iyanconywa ukuthuthukisa ukumelana namanzi nokunamathela;
I-putty yangaphandle yodonga engamelani nesimo sezulu: Umthamo ungandiswa ngendlela efanele ukuqinisekisa ukumelana nokuguguleka kwemvula kanye nokushintshashintsha kwezinga lokushisa kanye nomswakama. Kubalulekile ukuqaphela ukuthi i-RDP ibiza kakhulu, futhi ukwengeza okuningi kungalimaza ezomnotho futhi kunciphise ubulukhuni be-putty. Ngakho-ke, ukwenza ngcono kufanele kucatshangelwe ngendlela elinganiselayo yokusebenza kanye nezindleko.
I-RDPIdlala indima engenakuguqulwa ekuthuthukiseni ukumelana namanzi kwe-putty. Ngokwakha ifilimu, ukuthuthukisa ukunamathela, kanye nokuthuthukisa ukuguquguquka nokumelana nokuqhekeka, i-RDP ibhekana ngempumelelo nenkinga yokugaywa kwe-putty yendabuko nokuchitheka kwayo lapho ivezwa emanzini. Lokhu kuvumela i-putty ukuthi ingagcini nje ngokuhlangabezana nezidingo zokuhlobisa udonga lwangaphakathi kodwa futhi igcine ukuqina ezindaweni ezinomswakama nezangaphandle. Ukusetshenziswa okufanele kwe-RDP akugcini nje ngokuthuthukisa ukumelana namanzi kanye nokuphila kwenkonzo ye-putty kodwa futhi kukhuthaza ukuthuthukiswa kwezinto zokuhlobisa zokwakha ezisebenza kahle nezihlala isikhathi eside.
