Nga tono angamaheni o HPMC:
Whakapiri Tile
●He pai te pupuri i te wai: ka roa te whakatuwheratanga ka pai ake te mahi topa.
●I pai ake te adhesion me te retireti ātete: rawa hoki tāpa taimaha.
●He pai ake te mahi: te whakahinuhinu me te kirihou o te raima kua whakapumautia, ka ngawari ake te tono moata me te tere ake.
Te raima raima / moata whakaranu maroke
●Tatai ranunga maroke ngawari na te wai matao wairewa: ka taea te karo i te hanga putunga, he pai mo nga taera taumaha.
●He pai te pupuri i te wai: te aukati i te ngaronga o te wē ki ngā tïpako, ka mau te wai i roto i te ranunga kia roa ake te wa raima.
●Kua nui ake te hiahia wai: kua piki ake te wa tuwhera, kua nui ake te waahi pupuhi me te hanga ohanga.
●He ngawari ake te horapa me te pai ake o te atete kiore na te pai ake o te rite.
Puti pakitara
●Water te pupuri: whakanuia te ihirangi wai i roto i te slurry.
● Anti-sagging: ka horahia he koti koti matotoru ka taea te karo.
●Ka nui ake te hua o te moata: i runga i te taumaha o te ranunga maroke me te hanganga tika, ka taea e HPMC te whakanui ake i te riipene moata.
Pūnaha Wehenga o waho me te Whakaoti ( EIFS )
●Whakapai ake te piri.
●He pai te makuku mo te papa EPS me te tïpako.
●Whakaitihia te urunga o te hau me te tango wai.
Whakataurite-whaiaro
●Te parenga mai i te rere o te wai me te parataiao rawa.
●Karekau he paanga ki te slurry fluidity ki te pokey iti
HPMC, i te mea ko ona ahuatanga pupuri wai te whakapai ake i te mahi whakaoti i runga i te mata.
Kapiti Whakakii
●He pai ake te mahi: te matotoru tika me te kirihou.
●Ko te pupuri wai ka whakarite kia roa te wa mahi.
●Sag resistance: pai ake te kaha herenga kumete.
