VeoVa Based Redispersible Polymer Powder

I-VeoVa-based redispersible polymer powder (RDP) luhlobo lwe-polymer eyongeziweyo yomgubo esetyenziswa ngokuqhelekileyo kwizinto zokwakha, ezifana nodaka, i-tile adhesives, kunye ne-renders. I-VeoVa ibhekisela kwintsapho ye-vinyl ester monomers evela kwi-vinyl acetate kunye ne-versatic acid. Nantsi isishwankathelo se-RDP esekwe kwiVeoVa:

1. Ukwakheka:

• I-RDPs esekelwe kwi-VeoVa i-copolymers evela kwi-vinyl acetate (VA) kunye ne-VeoVa monomers. Inkqubo ye-copolymerization idibanisa ezi monomers ukwenza i-polymer eneempawu ezithile ezilungiselelwe izicelo ezahlukeneyo.

2. Iinkcazelo ngeempawu:

• I-RDPs esekelwe kwi-VeoVa inikezela uluhlu lwezinto ezinqwenelekayo, kubandakanywa ukubambelela okuphuculweyo, ukuguquguquka, ukuxhathisa kwamanzi, kunye nokuqina.
• Ukudityaniswa kwee-monomers ze-VeoVa kwisakhiwo sepolymer kuphucula ukusebenza kwe-RDPs xa kuthelekiswa nee-RDP zendabuko ezisekelwe kwi-VA kwizicelo ezithile, ngakumbi ezo zifuna ukuguquguquka okuphezulu kunye nokuchasana kwamanzi.

3. Usetyenziso:

• I-RDPs esekelwe kwi-VeoVa isetyenziswe kwizinto ezahlukeneyo zokwakha, kubandakanywa udaka, i-tile adhesives, i-grouts, i-self-leveling compounds, kunye ne-membrane yokukhusela amanzi.
• Zifaneleke ngokukodwa kwizicelo apho ukunyuka kokuguquguquka kunye nokuchasana kwamanzi kuyadingeka, njengokunikezelwa kwangaphandle, i-polymer-modified cementitious coatings, kunye neenkqubo zokukhusela amanzi.

4. Iinzuzo:

• Ukuguquguquka okuphuculweyo: Ii-RDP ezisekelwe kwi-VeoVa zibonelela ngokuguquguquka okuphuculweyo, okubavumela ukuba bamelane nokunyakaza kwe-substrate kunye nokutshintsha kweqondo lokushisa ngaphandle kokuqhekeka.
• Ukomelezwa kokumelana naManzi: Ubukho be-VeoVa monomers buphucula ukuxhathisa kwamanzi kwi-RDPs, ibenze bafanelekele izicelo zangaphandle ezivezwe kwiimeko zemozulu ezinzima.
• I-Adhesion ephezulu: I-RDPs esekelwe kwi-VeoVa ibonelela ngokugqwesa ngokugqwesileyo kwiintlobo ezahlukeneyo ze-substrates, kubandakanywa ikhonkrithi, i-masonry, iplanga, kunye neebhodi zokugquma, ukuqinisekisa ukubamba okuqinileyo kunye nokuqina kwexesha elide.

5. Ukuhambelana:

• I-RDPs esekelwe kwi-VeoVa iyahambelana nezinye izongezo ezisetyenziswa ngokuqhelekileyo kwizinto zokwakha, ezifana nesamente, iifayili, iiplastiki, kunye ne-air-entraining agents. Oku kuhambelana kuvumela ukuqulunqwa kodaka olucwangcisiweyo kunye neenkqubo zokunamathela ezilungiselelwe iimfuno ezithile zesicelo.

Isishwankathelo, i-VeoVa-based redispersible polymer powders (RDPs) inikezela ukuguquguquka okuphuculweyo, ukuchasana kwamanzi, kunye nokubambelela xa kuthelekiswa ne-RDPs yendabuko esekelwe kwi-VA, eyenza ukuba ifaneleke kakuhle kwizicelo ezininzi zokwakha apho ukuqina kunye nokusebenza kubaluleke kakhulu.
