Te paura polymer dispersible

1.Whakataki hua

Ingoa: VAEpaura taherapa marara

Tapaki: 25kg / putea

Ko te hua paura latex redispersible he paura rere ma te wai-wairewa, he ma ranei, he copolymer o te ethylene me te vinyl acetate, me te whakamahi i te waipiro polyvinyl hei colloid tiaki. Na te kaha o te here me nga ahuatanga ahurei o nga paura polymer dispersible, penei i te aukati wai, te mahi me te whakamaarama wera, he tino whanui te awhe tono. Ka whakamahia te nuinga ki te hanga, ina koa ki te whakanui ake i te whakakotahitanga, te whakakotahitanga me te ngawari ki te moata maroke.

4.Hua hua

He tino pai te mahi parewai, te kaha hono pai, te whakanui ake i te elasticity o te kumete me te roa ake o te wa tuwhera, e pai ai te moata te parenga alkali, me te whakapai ake i te adhesion/adhesion, te kaha flexible, te kirihou me te parenga o te moata. I tua atu i te mahi huri me te kaha mahi, he kaha ake te ngawari ki roto i te moata anti-ngapiti ngawari.

5.Ko te mahi o te paura polymer redispersible

Ko te paura polymer dispersible ka marara ki roto i te kiriata ka mahi hei whakakaha hei whakapiri tuarua.

Ko te colloid whakamarumaru ka uru ki te punaha kumete, ka kore e whakangaromia e te wai, "te marara tuarua" ranei i muri i te hanganga o te kiriata.

Ko te kapia polymer hanga kiriata ka mahi hei whakakaha kua tohatoha puta noa i te punaha moata, na reira ka piki ake te whakakotahitanga o te moata.

6.Ko te mahi o te whakamarara i te paura polymer i roto i te kumete

Ko te paura latex redispersible ka marara ki roto i te kiriata me te mahi hei taapiri tuarua hei whakarei ake i te piri;

Ko te colloid whakamarumaru ka uru ki te punaha kumete (kaore e whakakorea e te wai i muri i te hanganga o te kiriata. Ka marara rua ranei);

Ka tohatohahia te kapia polymer hanga kiriata puta noa i te punaha moata hei taonga whakakaha, na reira ka piki ake te whakakotahitanga o te moata.

Te mahi o te paura polymer dispersible i roto i te kumete maku

Whakapai ake i nga mahi hanga

Whakapai ake i nga ahuatanga rere

Whakanuia te thixotropy me te tohe

whakapai ake i te whakakotahitanga

Kua roa nga haora whakatuwheratanga

Whakanuia te pupuri wai

Te mahi o te paura redispersible i muri i te rongoa moata

Te kaha ake o te kaha (he taapiri taapiri i roto i nga punaha ciment);

Whakanuia te kaha flexural;

whakaiti i te taurangi elastic;

Whakapai ake te deformability;

Whakanuia te kiato rawa;

Whakapai ake i te aukati kakahu;

Whakapai ake i te kaha whakakotahi;

Whakaitihia te hohonutanga waro;

Whakaitihia te whakauru wai rauemi

7.Me pehea te rongoa o te hua RDP

Ko te paura polymer dispersible VAE me penapena ki te waahi makariri me te maroke. Ko te wa e tika ana mo te whakamahi ko te ono marama, no reira whakamahia wawe tonu i te raumati. Ko te rokiroki i roto i te pāmahana teitei me te makuku ka nui ake te tupono ki te hanga keke. I muri i te whakatuwheratanga o te putea, me whakamahi wawe tonu, mehemea ka hiahia koe ki te hiri i te putea kia kore ai e mimiti te makuku mai i te hau. Kaua e putu ki runga i nga palleti me te pupuri i nga peeke pepa i raro i te pehanga nui mo te wa roa kia kore ai e piri.
