Nga Mowhiti Konumina Ceramic

 

Ko te Alumina Ceramic te mea e whakamahia nuitia ana i nga rawa hangarau. He pakari te kakahu, te kaha miihini teitei, te aukati i te pāmahana teitei, te pai o te wiri waiariki, te pai o te whakamaarama hiko. Kei te nuinga whakamahia te reira no te insulators hiko, mau wahi ātete, wahi uku mo te teitei pāmahana oumu etc Alumina Ceramic e taea te hanga i te purenga rerekē rite 95%, 96%, 99%, 99.5%, 99.7% etc, ka iti o ratou taonga. rerekētanga. Ko te ahumahi Leap e whakarato ana i te parakore o te Ceramic he aha te mea e tika ana mo nga waahanga tono whakaritenga rereke.
