Mashandiro Akajairika eHPMC:
Tile Adhesive
● Kuchengetedza mvura kwakanaka: nguva yakareba yekuvhura ichaita kuti tiling iwedzere kushanda.
● Kunatsiridza kunamatira uye kutsvedza kuramba: kunyanya kune inorema mataira.
● Zvirinani kushanda: lubricity uye plasticity yepurasita inovimbiswa, dhaka rinogona kuiswa nyore uye nekukurumidza.
Cement Plaster / Dry musanganiswa dhaka
● Easy dry dry mix formula nekuda kwekunyungudika kwemvura inotonhora: bundu rekugadzira rinogona kudzivirirwa nyore nyore, rakanakira matairi anorema.
● Kuchengetedza mvura yakanaka: kudzivirira kurasikirwa kwemvura kune substrates, mvura yakakodzera inochengetwa mumusanganiswa iyo inovimbisa nguva yakareba concreting.
● Kuwedzera kudiwa kwemvura: nguva yakawedzerwa yakazaruka, nzvimbo yakawedzerwa yespry uye kuwedzera kwehupfumi.
● Kupararira kuri nyore uye nekuvandudza sagging kuramba nekuda kwekuvandudzwa kunoenderana.
Wall putty
● Kuchengetwa kwemvura: yakawedzera mvura yemukati mune slurry.
● Anti-sagging: kana uchiparadzira gobvu jasi corrugation inogona kudziviswa.
● Kuwedzera kwegoho redhaka: zvichienderana nehuremu hwemusanganiswa wakaoma uye kuumbwa kwakakodzera, HPMC inogona kuwedzera dhaka vhoriyamu.
Kunze Insulation uye Finish System (EIFS)
●Kunamira zvakanaka.
●Good wetting kugona kweEPS board uye substrate.
● Mhepo yakadzikira kupinda uye kutora mvura.
Kuzvimiririra
● Kudzivirirwa kubva pakubuda kwemvura uye kusvibiswa kwezvinhu.
● Hapana mhedzisiro pane slurry fluidity ine yakaderera viscosity
HPMC, nepo hunhu hwayo hwekuchengeta mvura hunovandudza kupedzisa kuita pamusoro.
Crack Filler
● Zviri nani kushanda: kukora kwakakodzera uye plastiki.
● Kuchengetwa kwemvura kunovimbisa kushanda kwenguva refu.
● Sag kuramba: yakagadziridzwa dhaka bonding kugona.
