Ko te paura polymer redispersible (RDP) he whakaehunga wai-wairewa polymer paura. Kei te whakamahia nuitia tenei rauemi i roto i te umanga hangahanga, ko te mea tuatahi hei here mo te raima me etahi atu mea hanga whare. Ko te kaha here o te RDP he tawhā nui mo tana tono na te mea ka pa tika ki nga ahuatanga o te hua whakamutunga. Na reira, he mea nui kia whai tikanga whakamatautau tika me te pono hei ine i te kaha here o te RDP.
Nga Tikanga Whakamatau
Rauemi
Ko nga rauemi e hiahiatia ana mo tenei whakamatautau ko enei e whai ake nei:
1. Tauira RDP
2. Sandblasted konumohe tïpako
3. Pepa whakapouri Resin (300um te matotoru)
4. Whakapiri wai
5. Mīhini whakamātautau tensile
6. Vernier caliper
hōtaka whakamātautau
1. Te Whakaritenga o nga tauira RDP: Me whakarite nga tauira RDP me te nui o te wai i tohua e te kaihanga. Me whakarite nga tauira kia rite ki nga whakaritenga tono.
2. Te takahanga o te papapa: Me horoi me te whakamaroke i mua i te whakamahi i te taputapu konumohe i muri i te pupuhi kirikiri. I muri i te horoi, me ine te taratara o te mata ki te caliper vernier.
3. Te tono o te RDP: Me tono te RDP ki te taputapu kia rite ki nga tohutohu a te kaihanga. Me ine te matotoru o te kiriata ma te whakamahi i te caliper vernier.
4. Whakaoranga: RDP kia rongoa i roto i te wa i tohua e te kaihanga. Ka rereke pea te wa whakaora i runga i te momo RDP i whakamahia.
5. Te whakamahi i te pepa kapia: Me tapahi te pepa kapia kia rite ki te rahi me te hanga. Me whakakikoruatia te pepa ki te whakapiri wai.
6. Te whakapiri i nga takai pepa: Me whakanoho nga takai pepa whakakikorua ki runga i te tïpako whakakikoruatia RDP. Me tono te pehanga marama kia pai ai te honohono.
7. Te whakaora: Me rongoa te whakapiri i roto i te wa i tohua e te kaihanga.
8. Te whakamatautau tensile: Utaina te tauira ki roto i te miihini whakamatautau. Me tuhi te kaha tensile.
9. Tatautanga: Ko te kaha here o te RDP me tatau ko te kaha e hiahiatia ana hei wehe i te taputapu whakakikorua RDP mai i te riipene pepa kua wehea e te waahi mata o te taputapu paninga RDP.
hei whakatau
Ko te tikanga whakamatautau he tikanga ngawari me te utu mo te ine i te kaha here RDP. Ka taea te whakamahi i tenei tikanga i roto i nga rangahau me nga waahi ahumahi hei whakarite i te mahi tino pai o te RDP i roto i te ciment me etahi atu mea hanga. Ma te whakamahi i tenei tikanga ka awhina i te whakapai ake i te mana kounga me te whanaketanga hua i roto i te umanga hanga.
