Yazisa:
I-putty yodonga lwangaphakathi idlala indima ephambili ekuphumezeni iindonga ezigudileyo, ezintle. Phakathi kwezithako ezahlukahlukeneyo ezenza ukwakhiwa kwe-putty eludongeni, i-polymer powders ephinda iphindwe kwakhona (RDP) ivelele indima ebalulekileyo abayidlalayo ekuphuculeni ukusebenza kunye neempawu zemveliso yokugqibela.
Icandelo loku-1: Ukuqonda iiPolymer Powders eziRedispersible (RDP)
1.1 Inkcazo nokwakheka:
I-RDP yipolymer powder eyenziwe nge-vinyl acetate, i-ethylene kunye nezinye ii-polymer monomers. Ngokuqhelekileyo iphuma kwi-synthetic resins kwaye i-binder ebalulekileyo kwi-putty formulations eludongeni.
1.2 Iimpawu ezibonakalayo:
I-RDP ibonakaliswe yi-powder morphology yayo, i-redispersibility egqwesileyo yamanzi kunye neempawu zokwenza ifilimu. Ezi zakhiwo zibaluleke kakhulu ekudityanisweni kwayo ngempumelelo kwizicelo ze-putty eludongeni.
Icandelo 2: Indima ye-RDP kwi-putty yangaphakathi yodonga
2.1 Nyusa ukuncamathela:
Omnye weyona misebenzi iphambili ye-RDP kwi-putty yangaphakathi eludongeni kukuphucula ukunamathela. I-polymer yenza ibhondi ehlala ixesha elide kunye ne-substrate, iqinisekisa ukuba i-putty ibambelela ngokuqinile eludongeni.
2.2 Ukuguquguquka kunye nokumelana nokuqhekeka:
I-RDP inika ukuguquguquka kwe-putty eludongeni, ukunciphisa umngcipheko wokuqhekeka kunye nokuqhekeka. Oku kubaluleke kakhulu kwiindawo zangaphakathi apho iindonga zingahamba kancinci ngenxa yokutshintsha kweqondo lokushisa okanye ukulungiswa kwesakhiwo.
2.3 Ukumelana namanzi:
Ukubandakanya i-RDP kunokuphucula kakhulu ukuxhathisa kwamanzi kwi-putty yangaphakathi yodonga. Le propati ibalulekile ukukhusela umonakalo obangelwa ngumswakama, ukuqinisekisa ixesha elide le-putty esetyenzisiweyo.
2.4 Ukwakhiwa kunye nokusasazeka:
I-RDP inceda ukuphucula iimpawu zesicelo se-putty eludongeni, okwenza kube lula ukuyifaka kunye nokusabalalisa ngokulinganayo kuwo wonke umhlaba. Olu phawu luluncedo kubo bobabini abafake izicelo abaziingcali kunye nabathandi be-DIY.
2.5 Ukuqina kunye nobomi:
Ukubandakanya i-RDP kwimixube ye-putty eludongeni kwandisa ukuqina okupheleleyo kwengubo. Oku kubalulekile ukugcina ingqibelelo yodonga kwixesha elide.
Icandelo 3: Inkqubo yokuvelisa kunye nomthamo we-RDP kwi-putty yangaphakathi yodonga
3.1 Inkqubo yokwenziwa kwemveliso:
Ukuveliswa kwe-putty yodonga lwangaphakathi kufuna ukuxuba ngokucophelela izithako ezahlukeneyo, kuquka i-RDP. Inkqubo yokwenziwa kwemveliso kufuneka iqinisekise ukusasazwa ngokufanayo kweRDP ukuze kuzuzwe umgangatho wemveliso ongaguqukiyo.
3.2 Elona thamo lifanelekileyo:
Ukumisela eyona mali ilungileyo ye-RDP ngumba ophambili wokuqulunqa i-putty yodonga lwangaphakathi. Oku kuxhomekeke kwizinto ezifana neempawu ezifunwayo ze-putty, uhlobo lwe-substrate kunye neemeko zokusingqongileyo.
Icandelo lesi-4: Imingeni kunye neengcinga ekusebenziseni i-RDP kwi-putty yangaphakathi yodonga
4.1 Imiba yokuhambelana:
Ngelixa i-RDP ibonelela ngezinto ezininzi ezilungileyo, ukuhambelana kwayo nezinye izongezo kunye nemathiriyeli ekrwada kufuneka iqwalaselwe ngexesha lenkqubo yokwenziwa kwayo. Ukungahambelani kunokuchaphazela kakubi ukusebenza kwe-putty eludongeni.
4.2 Impembelelo yokusingqongileyo:
Njengaso nasiphi na isongezelelo sekhemikhali, impembelelo yokusingqongileyo yeRDP kufuneka iqwalaselwe. Abavelisi bayanda bephonononga ezinye iindlela ezizinzileyo zokunciphisa unyawo lwendalo kwimveliso ye-putty eludongeni.
ukuququmbela:
Isishwankathelo, ukongezwa kwepolymer powder (RDP) kwi-putty yangaphakathi eludongeni kubalulekile ukufezekisa umgangatho ophezulu, ozinzileyo kunye nobuhle obuhle. Indima ye-RDP eneenkalo ezininzi ekwandiseni ukubambelela, ukuguquguquka, ukunganyangeki kwamanzi, ukusebenza kakuhle kunye nokuqina kwenza ukuba ibe sesona sithako siphambili kulwakhiwo lweputty eludongeni lwangoku. Njengoko ishishini liqhubeka nokuvela, abaphandi kunye nabavelisi banokuphonononga iindlela ezintsha zokwandisa inzuzo yeRDP ngelixa bejongana nemingeni enokubakho kunye neemeko zokusingqongileyo.
