Kodi ndi zinthu ziti zamatope zomwe zimatha kusinthanso ufa wa polima?

Redispersible polymer powders (RPP) amagwiritsidwa ntchito kwambiri popanga matope kuti apititse patsogolo zinthu zosiyanasiyana komanso magwiridwe antchito. Nazi zina mwazofunikira za matope zomwe RPP ingasinthe:

1. Kumatira: RPP imathandizira kumamatira kwa matope ku magawo monga konkire, miyala, matabwa, ndi zitsulo. Kumamatira kowonjezeraku kumathandizira kupewa delamination ndikuwonetsetsa kugwirizana kolimba pakati pa matope ndi gawo lapansi.
2. Flexural Strength: Kuphatikizira RPP m'mapangidwe amatope kumatha kukulitsa mphamvu yosunthika, kupangitsa kuti matopewo asavutike kusweka ndi kupunduka. Izi ndizofunikira makamaka pamapulogalamu omwe gawo lapansi limatha kusuntha kapena kukulitsa kutentha ndi kutsika.
3. Kusungirako Madzi: RPP imapangitsa kuti madzi asungidwe mumatope, zomwe zimapangitsa kuti zinthu za simenti zikhale zotalika. Izi zimapangitsa kuti pakhale kugwirira ntchito bwino, nthawi yotseguka yotalikirapo, komanso kumamatira bwino, makamaka pakatentha kapena mphepo.
4. Kugwira ntchito: RPP imapangitsa kuti matope azitha kugwira ntchito komanso kusasinthasintha, kupangitsa kukhala kosavuta kusakaniza, kuyika, ndi kufalitsa. Izi zimathandiza kuphimba bwino ndikugwiritsa ntchito mofanana, kuchepetsa mwayi wa voids kapena mipata mumatope omalizidwa.
5. Kuchepetsa Kutsika ndi Kusweka: Mwa kukonza kumamatira, kusinthasintha, ndi kusunga madzi, ma RPP amathandiza kuchepetsa kuchepa ndi kuphulika mumatope. Izi ndizopindulitsa makamaka m'mapulogalamu omwe ming'alu ya shrinkage imatha kusokoneza kukhulupirika ndi kulimba kwa matope.
6. Kukhalitsa: Kugwiritsa ntchito RPP kumatha kukulitsa kulimba kwa matope powonjezera kukana kwake ku nyengo, kuukira kwamankhwala, ndi abrasion. Izi zimabweretsa matope okhalitsa omwe amasunga umphumphu wake pakapita nthawi.
7. Kukaniza kwa Kutentha ndi Chinyezi: RPP imatha kupititsa patsogolo kukana kwamafuta ndi chinyezi chamatope, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo osiyanasiyana achilengedwe, kuphatikiza kuzungulira kwa kuzizira, chinyezi chambiri, komanso kusinthasintha kwa kutentha.
8. Mphamvu ya Bond: RPP imathandizira kuti mgwirizano ukhale wolimba wamatope, kuonetsetsa kuti palimodzi pakati pa zigawo zamatope ndi pakati pa matope ndi gawo lapansi. Izi ndizofunikira kuti tikwaniritse misonkhano yomanga yodalirika komanso yokhalitsa.

kuphatikizika kwa ufa wa polima wogawanikanso m'mapangidwe amatope kumapereka maubwino ambiri, kuphatikiza kumamatira bwino, kusinthasintha kwamphamvu, kusunga madzi, kutha ntchito, kulimba, komanso kukana kutsika, kusweka, ndi chilengedwe. Zowonjezera izi zimapanga matope osinthidwa a RPP oyenera ntchito zosiyanasiyana zomanga, kuphatikizapo kuika matailosi, stucco ndi pulasitala, kukonzanso ndi kubwezeretsa, ndi kuletsa madzi.
