Yintoni indlela yokusebenza kwepolymer powder ephinda ihlakazwe?

Indlela yokwenza i-polymer powders (RPP) i-redispersible powders ibandakanya ukusebenzisana kwabo namanzi kunye nezinye iinqununu zokwenziwa kodaka, okukhokelela ekusebenzeni okuphuculweyo kunye neepropati. Nantsi ingcaciso enzulu yendlela yokusebenza ye-RPP:

1. Ukusasazwa kwakhona emanzini:
   • I-RPP yenzelwe ukusabalalisa ngokukhawuleza emanzini, ukwenza ukumiswa kwe-colloidal okuzinzileyo okanye izisombululo. Oku kuphinda kuphinde kwenzeke kwakhona kubalulekile ekudityanisweni kwazo kwimixube yodaka kunye ne-hydration elandelayo.
2. Ukwenziwa kwefilimu:
   • Emva kokusasazwa kwakhona, i-RPP yenza ifilimu encinci okanye i-coating ejikeleze amasuntswana e-samente kunye namanye amacandelo e-matrix yodaka. Le filimu isebenza njenge-binder, idibanisa amaqhekeza kunye nokuphucula ukudibanisa ngaphakathi kodaka.
3. Ukuncamathela:
   • Ifilimu ye-RPP iphakamisa ukunamathela phakathi kwezinto zodaka (umzekelo, i-samente, i-aggregates) kunye ne-substrate surfaces (umz., ikhonkrithi, i-masonry). Oku kubambelela okuphuculweyo kuthintela i-delamination kwaye kuqinisekisa ukudibanisa okuqinileyo phakathi kodaka kunye ne-substrate.
4. Ugcino lwamanzi:
   • I-RPP ineempawu ze-hydrophilic ezenza ukuba zifunxe kwaye zigcine amanzi ngaphakathi kwe-matrix yodaka. Oku kunyuswa kokugcinwa kwamanzi kwandisa ukuhanjiswa kwezinto ze-cementitious, okukhokelela ekusebenzeni okungcono, ixesha elivulekileyo elongezelelweyo, kunye nokuphucula ukunamathela.
5. Ukuguquguquka kunye noKulula:
   • I-RPP inika ukuguquguquka kunye nokunwebeka kwi-matrix yodaka, iyenza ixhathise ngakumbi ukuqhekeka kunye nokuguqulwa. Oku kuguquguquka kuvumela udaka ukuba lubambe ukunyakaza kwe-substrate kunye nokwandiswa kwe-thermal / ukucutha ngaphandle kokuphazamisa ingqibelelo yayo.
6. Ukuphuculwa kokuSebenza:
   • Ubukho be-RPP buphucula ukusebenza kunye nokuhambelana kodaka, okwenza kube lula ukuxuba, ukusebenzisa, kunye nokusabalalisa. Oku kusebenza okuphuculweyo kuvumela ukugqunywa ngcono kunye nesicelo esifanayo, ukunciphisa ukubakho kwe-voids okanye izithuba kudaka olugqityiweyo.
7. Ukomelezwa koKuhlala:
   • Udaka oluguquliweyo lwe-RPP lubonisa ukomelela okuphuculweyo ngenxa yokuxhathisa okuphuculweyo kwimeko yemozulu, uhlaselo lweekhemikhali, kunye nokuqhawuka. Ifilimu ye-RPP isebenza njengesithintelo sokukhusela, ukukhusela udaka kubahlaseli bangaphandle kunye nokwandisa ubomi bayo benkonzo.
8. Ukukhutshwa okuLawulwayo kwezongezo:
   • I-RPP inokubamba kwaye ikhulule izithako ezisebenzayo okanye izongezo (umzekelo, iiplastiki, ii-accelerators) ngaphakathi kwe-matrix yodaka. Le ndlela yokukhululwa elawulwayo ivumela ukusebenza okulungiselelwe kunye nokuqulunqwa okulungiselelwe ukuhlangabezana neemfuno ezithile zesicelo.

indlela yokusebenza yepolymer powders enokuphinda ihlakazwe kwakhona ibandakanya ukusasazwa kwakhona emanzini, ukubunjwa kwefilimu, ukuphuculwa kokunamathela, ukugcinwa kwamanzi, ukuphuculwa kokuguquguquka, ukongezwa kokusebenza, ukomeleza ukuqina, kunye nokukhululwa okulawulwayo kwezongezo. Ezi ndlela zidibeneyo zifaka isandla ekusebenzeni okuphuculweyo kunye neepropati ze-RPP-modified mortars kwizicelo ezahlukeneyo zokwakha.
