Xikmad
Huajing budada mica-fasalka balaastigga ah, oo inta badan loo isticmaalo balaastikada injineernimada si loo kordhiyo qaabka foorarsiga iyo dabacsanaanta; si loo yareeyo yaraanshaha .Beeraha qalabka balaastigga ah ee alaabada elektarooniga ah, ka dib markaad ku darto mica, waxay noqon karaan kuwo isku dhafan oo isku dhafan oo leh qaabeyn. waxay hagaajin kartaa caabbinta cimilada ee alaabada caagga ah, sidaa darteed caagagga injineernimada waxay u adkeysan karaan heerkulka weyn iyo kala duwanaanshaha deegaanka; waxay si weyn u hagaajineysaa daboolka si loo hubiyo kalsoonida hawlgalka korantada sare; Waxay kor u qaadi kartaa dheecaanka qaar ka mid ah alaabada caagga ah sidoo kale.
Mica dahabka ah badanaa waa jaalle, bunni, bunni madow ama madow; dhaldhalaalka dhalada, dusha jeexjeexa ayaa ah luul ama nuurad bir ah. Hufnaanta Muscovite waa 71.7-87.5%, iyo tan phlogopite waa 0-25.2%. Dhibaatada Mohs ee Muscovite waa 2-2.5 iyo tan phlogopite waa 2.78-2.85.
Dabacsanaanta iyo sifooyinka dusha sare ee Muscovite isma beddelaan marka la kululeeyo 100,600C, laakiin fuuqbaxa, guryaha farsamada iyo korontada ayaa isbedela ka dib 700C, dabacsanaantii ayaa luntay waxayna noqoneysaa mid jajaban, qaabdhismeedkuna wuxuu ku burburay 1050 ° C. marka Muscovite uu qiyaastii yahay 700C, waxqabadka korantada ayaa ka wanaagsan Muscovite.
Sidaa darteed, mica dahabka waxaa loo isticmaalaa balaastikada oo aan lahayn shuruudo sare oo midab laakiin iska caabinta heerkulka sare.
Codsiga Mica ee PA
PA waxay leedahay saameyn saameyn hoose leh iyo u nuglaansho sare heerkulka qalalan iyo hooseeya, taas oo saameyn ku leh xasiloonida cabbirkeeda iyo guryaha korantada. Sidaa darteed, waa lagama maarmaan in wax laga beddelo cilladaha PA si ula kac ah.
Mica waa filler aad u fiican oo dabiici ah oo loogu talagalay caagagga, kaas oo leh astaamaha u adkaysiga cimiladu aad u fiican tahay, iska caabbinta kuleylka, u adkaysiga daxalka kiimikada, adkaanta, dahaadhka korantada iyo wixii la mid ah. Waxay leedahay qaab dhismeed jilicsan waxayna kobcin kartaa PA laba dhinac. Ka dib markii wax laga beddelay dusha sare, mica ayaa lagu daray PA resin, guryaha farsamada iyo xasiloonida kuleylka ayaa si weyn loo hagaajiyay, hoos u dhigista waxqabadka ayaa sidoo kale si weyn loo hagaajiyay, iyo qiimaha wax soo saarka si weyn ayaa loo dhimay.
