IiModyuli zePolymer

Iimodyuli zePolymer zizinto ezongezwa kwiipolymers ukuphucula ukusebenza kwazo okanye ukunika iimpawu ezintsha. Kukho iindidi ngeendidi zezilungisi zepolymer, kubandakanya izihluzi, iiplasticizers, i-crosslinking agents, kunye ne-reactive diluents, phakathi kwezinye. Olunye uhlobo lwesilungisi sepolymer esiqhele ukusetyenziswa kwizinto zokwakha yiRedispersible Polymer Powder (RDP).

I-Redispersible Polymer Powder (RDP) luhlobo lwe-polymer modifier esetyenziswa kwizinto zokwakha ezifana ne-cementitious mortars, i-adhesives ye-tile, kunye ne-self-leveling compounds. Yenziwe ngokutshiza-yomisa umxube we-polymer emulsion kunye ne-colloid yokukhusela, kwaye ngokuqhelekileyo isekelwe kwi-vinyl acetate-ethylene (VAE) okanye i-ethylene-vinyl acetate (EVA) copolymers.

I-RDP ngumgubo omhlophe, okhululekileyo onokuthi usasazwe ngokulula emanzini. Xa ixutywe ngamanzi kunye nezixhobo ze-cementitious, yenza ifilimu ezinzileyo, eguquguqukayo, kunye nesigxina esiphucula iimpawu zezinto zokwakha. Ezinye zezibonelelo zokusebenzisa iRDP njengesilungisi sepolymer ziquka:

1. Ukusebenza okuphuculweyo: i-RDP iphucula ukusebenza kwezixhobo zesamente ngokunciphisa umthamo wamanzi kunye nokuphucula i-rheology. Oku kubangela ukunamathela okungcono, ukuphatha lula, kunye nokunciphisa ukuqhekeka.
2. Ukunyuka kwamandla: i-RDP iphucula amandla kunye nokuqina kwezinto ze-cementitious ngokunyusa amandla ebhondi kunye nokunciphisa ukunyanzeliswa. Oku kubangela imathiriyeli yokwakha eyomeleleyo kunye neyomelele ngakumbi.
3. Ukuchasana ngcono kumanzi kunye neekhemikhali: I-RDP iphucula ukuxhathisa kwezixhobo ze-cementitious kumanzi kunye neekhemikhali ngokunciphisa i-porosity kunye nokuphucula ukungakwazi ukungena. Oku kubangela imathiriyeli yolwakhiwo engangenwa ngamanzi ngakumbi kwaye ikwazi ukumelana neekhemikhali.
4. Ukunamathela okungcono: I-RDP iphucula ukuncamathelwa kwezixhobo zesamente kwiintlobo ngeentlobo zesubstrates, ezibandakanya ikhonkrithi, i-masonry, kunye nemithi. Oku kubangela ukuba kubekho ibhondi eyomeleleyo kunye neyomelele ngakumbi phakathi kwezinto zokwakha kunye ne-substrate.

I-RDP isetyenziswa kwizinto ezahlukeneyo zokwakha, kuquka:

1. Udaka lwesamente: I-RDP isetyenziswa kwiidaka zesamente ezifana nokunamathelisa iithayile, iigrouts, kunye neerenders. Iphucula ukusebenza, amandla, kunye nokuqina kwezi zixhobo, okukhokelela ekugqityweni okungcono kunye nobomi obude.
2. I-self-leveling compounds: I-RDP isetyenziselwa ukulinganisa i-self-leveling compounds ukuphucula ukuhamba kwayo kunye neempawu zokulinganisa. Ikwaphucula amandla abo kunye nokuqina, okukhokelela ekugqityweni okungcono.
3. Iimveliso ezisekelwe kwiGypsum: I-RDP isetyenziswa kwiimveliso ezisekwe kwigypsum ezifana neekhompawundi ezidityanisiweyo kunye nesamente. Iphucula ukusebenza, amandla, kunye nokuqina kwezi mveliso, okukhokelela ekugqityweni okugudileyo kunye nobomi obude.
4. Izinto zokugquma: I-RDP isetyenziselwa izinto zokukhusela ezifana nodaka lwe-thermal kunye neengubo. Iphucula ukunamathela, ukomelela, kunye nokuqina kwezi zixhobo, okukhokelela ekugqumeni okungcono kunye nobomi obude.

Ukuqukumbela, i-Redispersible Polymer Powder (RDP) luhlobo lwe-polymer modifier esetyenziswa ngokuqhelekileyo kwizinto zokwakha ukuphucula iimpawu zabo. Iphucula ukusebenza, ukomelela, kunye nokuqina kwemathiriyeli yesamente, okukhokelela ekugqityweni okungcono kunye nobomi obude. I-RDP isetyenziswa kwizinto ezahlukeneyo zokwakha ezifana nodaka lwesamente, iikhompawundi zokuzilinganisa, kunye neemveliso ezisekwe kwigypsum, phakathi kwezinye.
