結果表明：用水玻璃砂型（芯）加負壓鑄滲的工藝能夠實現復雜表面（曲面）顆粒增強復合材料的制備，澆注方式簡單可靠，基材厚度在10mm時，復合層厚度能達到3 5mm ，且復合層鑄造缺陷少，復合效果好，界面緻密而且結合強度高。Explanation : this is kind of sand which is washed. got rid of clay. graded and disposed sarface. and it. saiso molding and core sand used in casting iron and middlesmall sized casting stee
水洗硅砂系列：這是一種經過洗滌、脫泥、分級和表面處理的砂，具有較清潔的原形顆粒，用於鑄鐵件，中小型鑄鋼件的型芯砂。After 20 days at 450 or 1 day at 500, the u3si2 particles cracked and fragmented, there were a lot of cracks in al - matrix and reacted areas, there were also a lot of holes in the meat. the meat lost its continuity and perfection, and departed from clad. above 450 the volume fraction of the al - matrix and the u3si2 decreased and produced u ( al, si ) 3 in the meat, u3si2 particles invaded to clad
在450熱循環20天後、 500熱循環1天後，燃料板的厚度變化一般0 . 04mm ，燃料板的翹曲現象嚴重； u _ 3si _ 2顆粒開裂及破碎，基體中產生大量的裂縫，反應層也存在大量的裂紋及孔洞，芯體已失去連續性、完整性，並且與包殼脫開。Four. slit - type exhaust punch : applicable to the ultra - micro powder polished tile, grain polished tile, fancy polished tile, etc
四、槽式排氣模芯；適用於超微粉、顆粒、夢幻等拋光磚。After 60 days at 160, 250, 350 and 400, u3si2 particles are compact with al - matrix, the meat did not crack and there were no phase change. fuel meat and clad binded tightly, no crack was found at the boundary of the meat and clad
從微觀觀察發現， u _ 3si _ 2顆粒與al基體結合緊密，沒有碎化，芯體沒有開裂，並且與包殼的結合處沒有脫開及發現裂縫，芯體中也沒有發生相變化，未發生鈾硅顆粒向包殼侵入的現象。No u3si2 particles invaded to clad and the clad did not become thinner ( > 0. 3mm ). the fuel meat exposing to air at 160 and 250 did not affect the thermal performance considerably, but at 350 and 400, u3si2 particles fragmented, the meat cracked, u3si2 particles invaded to clad and the clad became thinner ( < 0. 2mm )
芯體暴露在160 、 250較低溫度下對包殼及芯體的性能均沒有顯著影響；但芯體暴露的金相預制試樣， 350 、 400熱循環60天後， u _ 3si _ 2顆粒的碎化現象嚴重， al基體中有大量裂縫及裂紋，嚴重時芯體已經裂開。It is made of special filtering materid and also can be used to filter all leuds of medium and has high filtering mecision, especially composite filtering material is used inside in order to expand foul capacity storde in to filfering layers of filtering elements and molong to service life of filtering elements
採用了新研製的特殊濾材，可對多種介質進行超細顆粒污染的過濾，過濾精度高。使用特別復合濾材，擴大了濾芯濾層的納污容量，延長了濾芯的使用壽命。Above 450, the formation of low density u ( al, si ) 3 phase, together with the release of the impurity gas and fragmentation of u3si2 particles, will cause fuel meat to swell, al matrix to crack and u3si2 particles to invade to clad. as a result, the thickness of the meat increased, the thickness of clad decreased and the deformation of fuel plates increased, and the leakage probability of the radioactive mass increased reasonably
同時，由於芯體膨脹及鈾硅顆粒碎裂的綜合作用，使u _ 3si _ 2顆粒向包殼侵入，最終使燃料板芯體厚度增加較大，芯體及燃料的體積也顯著增加，包殼厚度減薄；高溫將加速芯體u _ 3si _ 2顆粒碎裂、芯體開裂、包殼以及燃料板變形，從而使燃料芯體與包殼脫開，最終可能導致放射性物質泄漏。分享友人
