Yiziphi izakhiwo zodaka olungavuselela i-polymer powder ethuthukile?

Ama-polymer powders (RPP) asetshenziswa kakhulu ekwakhiweni kodaka ukuthuthukisa izakhiwo ezahlukahlukene kanye nezimpawu zokusebenza. Nazi ezinye zezakhiwo ezibalulekile zodaka olungathuthukisa khona i-RPP:

1. I-Adhesion: I-RPP Thuthukisa ukunamathela kodaka ku-substrates njengokukhonkolo, ubumbano, izinkuni kanye nezindawo zensimbi. Lokhu kunamanzi okuthuthukisiwe kusiza ukuvikela ukubekelwa phansi futhi kuqinisekise ukubopha okuqinile phakathi kosimende kanye ne-substrate.
2. Amandla we-Flexiral: Ukufaka i-RPP ekwakhiweni kodaka kungakhulisa amandla aguqukayo, okwenza udaka olungamelana nokuqhekeka kanye nodoti. Lokhu kubaluleke kakhulu kuzinhlelo zokusebenza lapho i-substrate ingathola khona ukunyakaza noma ukwanda okushisayo kanye nokuwohloka.
3. Ukugcinwa kwamanzi: I-RPP ikhulisa izakhiwo zokugcina amanzi zodaka, ivumela i-hydration ende ye-perject yezinto zokwakha dementile. Lokhu kuphumela ekusebenzeni okungcono, okwenziwe isikhathi esivulekile, kanye nokunamathela okuthuthukile, ikakhulukazi ezimweni ezishisayo noma ezinomoya.
4. Ukusebenza: I-RPP ithuthukisa ukuwenza nokuvumelana kodaka, okwenza kube lula ukuxuba, ukufaka isicelo, nokusakazeka. Lokhu kuvumela ukumbozwa okungcono kanye nesicelo esifanayo, ukunciphisa amathuba okuvela noma izikhala kudaka oluqediwe.
5. Yehlisa i-shrinkage kanye nokuqhekeka: Ngokuthuthukisa ukunamathela, ukuguquguquka, nokugcinwa kwamanzi, ama-RPPs asiza ukunciphisa ukushwabana nokuqhekeka ngodaka. Lokhu kuyazuzisa kakhulu kuzinhlelo zokusebenza lapho ukuqhekeka okuthe xaxa kunganciphisa ubuqotho nokuqina kodaka.
6. Ukuqina: Ukusetshenziswa kwe-RPP kungathuthukisa ukuqina kodaka ngokwandisa ukumelana kwayo ekuhlaseleni isimo sezulu, ukuhlasela kwamakhemikhali, kanye ne-abrasion. Lokhu kuphumela kudaka oluhlala isikhathi eside olugcina ubuqotho bayo obuhle kakhulu ngokuhamba kwesikhathi.
7. Ukumelana okushisayo kanye nomswakama: I-RPP ingathuthukisa ukumelana okushisayo nowomswakama wodaka, okwenza lufanele ukusetshenziswa ezinhlotsheni ezahlukahlukene zezemvelo, kufaka phakathi ukuguquguquka okuguquguqukayo kweqhwa, ukuguquguquka komswakama ophezulu, nokushintshashintsha komswakama.
8. Amandla e-Bond: I-RPP inikela ngamandla ebhondi kadaka, iqinisekisa ukunamathela okuqinile phakathi kwezendlalelo zodaka ngawodwana kanye nodaka kanye nosiko. Lokhu kubalulekile ekufezeni imihlangano yokwakha ethembekile nehlala isikhathi eside.

Ukufakwa kwe-polymer powders evuselelayo ekwakhiweni kodaka kunikeza izinzuzo eziningi, kufaka phakathi ukunxusa okuthuthukile, ukugcinwa kwamanzi, ukugcinwa kwamanzi, ukumelana, ukuqina, kanye nezici zezemvelo. Lezi zithuthukisi zenza odongeni oluguqulwe nge-RPP zilungele izicelo ezahlukahlukene zokwakha, kufaka phakathi ukufakwa kwamathayela, i-tucco kanye nokubuyiselwa, ukulungisa nokubuyiselwa, nokuvuselelwa kwamanzi.
