Tire whakakī muka whatu
Whakaahuatanga Poto:
Ka hangaia e te ahumahi taura whatu whatu taura whatu whatu ma te awhi i nga muka whatu i roto i te sheathing polymeric.Ka whakatakotoria he tiēre ki waenga i te kurupae polymeric me te muka whatu.Ko te kaupapa o tenei tiēre ko te whakarato i te parenga wai, hei parepare hoki ki te whakapiko i nga taumahatanga me nga uaua.Ko te tiēre he hinu kore-Newtonian.
Ko te ahua kore-Newtonian ka taea te tiēre kia angiangi i te wa o te tukatuka me te whakanoho i muri i te tangohanga o nga kaha kutikuti.Ko nga tawhā tino nui e whai ana i nga mahi e tika ana ko te pokey i nga momo reiti kutikuti me te taumahatanga tuku.I te nuinga o te wa ka mahia te tiēre ma te hinu me te kaitakawaenga pararopi ranei.Ko nga mea whakakaha parakore i whakamahia mai i te uku pararopi ki te silica.Ka whakatarewahia enei momo whakapouri ki roto i te hinu hydrophobic penei i te hinu kohuke, te hinu waihanga ranei.I tua atu, ka whakauruhia nga kaiwhakamau hei whakarite i te pumau o te whakangao.
● XF-400 he hototahi ki te paninga kapia kiriaku me nga rauemi waerau mo nga tono muka me te taura.
● E taunaki ana kia whakamatauria nga rauemi polymer katoa e pa ana ki te whakapiri mo te hototahi i te wa e whakamahia ana.
● Ko te XF-400 i hangaia mo te tukanga whakakii makariri e karo ana i nga koretake na te whakapiri i te whakaheke.
