Paura Alumina Porohita mo nga Rauemi Atanga Ngawha
Whakaahuatanga Hua
Ko te raupapa HRK konumohe porowhita ka whakaputahia e te tikanga whakarewa-jet teitei e whanake ana i runga i te ahua kohikohiko noa Al2O3, katahi ka tirotirohia, ka purea me etahi atu tukanga kia whiwhi ai i te hua whakamutunga.Ko te alumina kua whiwhi he reeti spheroidization teitei, te tohatoha rahi matūriki ka taea te whakahaere me te parakore teitei.Na ona ahuatanga ahurei penei i te kaha o te waiariki me te pai o te nekenekehanga, Kua whakamahia te hua hei whakakii i nga rauemi atanga waiariki, nga kirihou miihini waiariki me nga Laminates Copper-Clad Laminates konumohe me etahi atu.
