Applications:
Wall putty
- Kuchengeta mvura: yakawedzera mvura yemukati mune slurry.
- Anti-sagging: kana uchiparadzira gobvu jasi corrugation inogona kudzivirirwa.
- Kuwedzera goho redhaka: zvichienderana nehuremu hwemusanganiswa wakaoma uye kugadzirwa kwakakodzera, HPMC inogona kuwedzera dhaka vhoriyamu.
Kunze Insulation uye Finish System (EIFS)
- Kuvandudzwa kwekunamatira.
- Yakanaka wetting kugona kweEPS board uye substrate.
- Yakaderedzwa kupinda kwemhepo uye kutora mvura.
Kuzvimiririra
Kudzivirirwa kubva kumvura exudation uye zvinhu sedimentation.
Hapana mhedzisiro pane slurry fluidity ine yakaderera viscosity
HPMC, nepo hunhu hwayo hwekuchengeta mvura hunovandudza kupedzisa kuita pamusoro.
Crack Filler
Zvirinani kushanda: ukobvu hwakakodzera uye plastiki.
Kuchengetwa kwemvura kunovimbisa kushanda kwenguva refu.
Sag kuramba: yakagadziridzwa dhaka kubatanidza kugona.
Tile Adhesives
Zvirinani kushanda: lubricity uye plasticity yepurasita inovimbiswa, dhaka rinogona kuiswa nyore uye nekukurumidza.
Kuchengetwa kwemvura kwakanaka: nguva yakareba yekuvhura ichaita kuti tiling ishande.
Yakavandudzwa kunamatira uye kutsvedza kuramba: kunyanya kune anorema mataira.
Dry mix dhaka
Nyore yakaoma yakaoma musanganiswa formula nekuda kwekunyungudika kwemvura inotonhora: kuumbwa kwebundu kunogona kudzivirirwa nyore, kwakanakira mataira anorema.
Kuchengetwa kwemvura kwakanaka: kudzivirira kurasikirwa kwemvura kune substrates, iyo yakakodzera mvura yemukati inochengetwa musanganiswa iyo inovimbisa yakareba concreting nguva.
Cement Plaster
Kuwedzera kudiwa kwemvura: yakawedzera yakavhurika nguva, yakawedzera spry nzvimbo uye kuwedzera kwehupfumi kuumbwa.
Kupararira kuri nyore uye nekuvandudza sagging kuramba nekuda kwekuvandudzwa kuenderana.
Kurongedza:
HPMC Chigadzirwa chakarongedzwa mutatu pepa bhegi rine mukati me polyethylene bhegi rakasimbiswa, huremu hwemambure i25kg pabhegi.
Kuchengeta:
Chengetedza munzvimbo inotonhorera yakaoma yakaoma, kure nehunyoro, zuva, moto, mvura.
