Uyini umkhuba wesenzo se-polymer powder powder?

Indlela yokusebenza kwe-polymer powders (RPP) ifaka ukuxhumana kwayo ngamanzi nezinye izinto zokwakhiwa kodaka, okuholela ekusebenzeni okuthuthukile kanye nezakhiwo. Nansi incazelo enemininingwane yohlelo lokusebenza lwe-RPP:

1. Ukuhlehlisa emanzini:
   • I-RPP yenzelwe ukusabalalisa kalula emanzini, yakha izinsolo noma izixazululo ezizinzile ze-colloidal. Lokhu kubuyiselwa emuva kubalulekile ekuthobeni kwabo kube ukwakheka kodaka kanye ne-hydration elandelayo.
2. Ukwakheka kwamafilimu:
   • Phezu kokubuyiselwa emuva, i-RPP yakha ifilimu elincanyana noma i-coapation ezungeze izinhlayiya zosekhukhwini nezinye izingxenye ze-matrix yodaka. Le filimu isebenza njenge-binder, ibopha izinhlayiya ndawonye kanye nokwenza ngcono ukubumbana ngaphakathi kodaka.
3. Adhesion:
   • Ifilimu le-RPP lithuthukisa ukunamathela phakathi kwezakhi zodaka (isib. Isimende, ama-aggregates) nezindawo ezingaphansi komhlaba (isib. Ukhonkolo, ubumbano). Lokhu kunamanzi okuthuthukile kuvimbela ukudicilela phansi futhi kuqinisekise ukubopha okuqinile phakathi kosimende kanye ne-substrate.
4. Ukugcinwa kwamanzi:
   • I-RPP inezakhiwo ze-hydrophilic ezibenza bakwazi ukudonsa futhi bagcine amanzi ngaphakathi kwe-matrix yodaka. Lokhu kugcinwa kwamanzi okukhulayo kwandisa i-hydration yezinto zokwakha i-cementional, okuholele ekusebenzikeni okungcono, isikhathi esivulekile esandisiwe, nokunamathela okuthuthukile.
5. Ukuvumelana nezimo kanye nokuqina:
   • I-RPP idlulisela ukuguquguquka nokuqina ku-matrix kadaka, okwenza kube nokumelana nokuqhekeka nokukhubazeka. Lokhu kuguquguquka kuvumela udaka ukuze amukele ukunyakaza okungaphansi kokwanda / ukwanda kwe-thermal ngaphandle kokuyekethisa ubuqotho bayo.
6. Ukusebenza okwenziwe ngcono:
   • Ukuba khona kwe-RPP kuthuthukisa ukusebenziseka nokuvumelana kodaka, okwenza kube lula ukuxuba, ukufaka isicelo, nokusabalala. Lokhu kusebenza okuthuthukile kuvumela ukumbozwa okungcono kanye nohlelo olufanayo olufanayo, kunciphisa amathuba okuba vele voids noma izikhala kudaka oluqediwe.
7. Ukuthuthukiswa kokuqina:
   • UDormars oguqulwe kabusha we-RPP Ubonisa ukuqina okuthuthukile ngenxa yokumelana kwabo okuthuthukile ekuhlaseleni isimo sezulu, ukuhlasela kwamakhemikhali, kanye ne-abrasion. Ifilimu le-RPP lisebenza njengesithiyo esivikelayo, livimbela udaka oluvela ngaphandle kwangaphandle futhi lande impilo yalo yenkonzo.
8. Ukukhishwa okulawulwayo kwezengezo:
   • I-RPP ingavuma futhi idedele izithako ezisebenzayo noma izengezo (isib. Amapulangwe, ama-accelerator) ngaphakathi kwe-matrix. Le ndlela yokukhishwa elawulwayo ivumela ukusebenza okuhambisana nokusebenza okwenziwe ngezifiso ukufeza izidingo ezithile zohlelo lokusebenza.

Indlela yokusebenza kwama-polymer powders abuyiselwa emanzini, ukwakheka kwamafilimu, ukuthuthukiswa kwamanzi, ukuthuthukiswa kwamanzi, ukuthuthukiswa kokusebenza, ukuthuthukiswa kokusebenza, ukukhiqizwa kokuqina, nokukhishwa okulawulwa kwezithasiselo. Lezi zinqubo ezihlangene zinikela ngokusebenza okuthuthukile kanye nezakhiwo zodonga lwe-RPP-modified dotis kuzicelo ezahlukahlukene zokwakha.
