Product introduction series of bs undulate screen, which surface are made of more line - up and row peach shape screen pieces, its rotor is circumrotate by same direction and equal speed, the screen surface intervene turning make of levity screen hole, drive materiel above screen go forward with undulate form, thereby reach to separate effectively
產品介紹bs系列波動篩分機是由轉子上多排多元並列的特製桃形篩片組成篩面，轉子以同向等速做周向旋轉，篩片交錯回轉構成多變的篩孔，使篩上物料以波動形式向前運動，從而達到高效篩分之目的。This machine adopts one pair of rotating grinding blade to grind form damp material into column - shape granule by stainless steel sieve cylinder which is provided for pelletize in next process
本機是通過一組旋轉碾刀，將前道工序製成的濕材注入環碾刀的不銹鋼篩筒篩孔中，從而製成圓柱狀的濕顆粒，供下道工序拋丸使用。本設備可通過更換不銹鋼篩筒來取得不同大小的顆粒。This paper analyzed the mechanism that gas and liquid flow through the holes according to the fluid characteristics of the compound tray, and put forward that there are three states of liquid flowing, gas flowing and blocked for the holes because of the foam fluctuating on the tray while the compound tray operates
本文根據復合塔板的氣液流動特點，分析了氣液穿孔流動的機理。根據前人的研究結果，提出復合塔板在操作時，由於泡沫層的波動，其篩孔存在通氣、通液和阻塞三種狀態。The group established r d center, with very powerful technical backup, mainly exploits and manufactures products of xinfa brand, including polyurethane sieve - plates pu sieve - plates, polyurethane roller pu roller, pu slice, pu bar, pu piece, pu elastic web gears and other polyurethane elastomer
鑫發聚氨酯篩板是使用高分子聚合材料聚氨酯，部分內嵌金屬骨架構成。聚氨酯是一種高分子聚合材料又稱「橡膠之王」 ，以前大部分篩板篩網是由不銹鋼金屬絲多孔板高彈線和傳統橡膠製成。This paper reviews the recent developments in the application of mesoporous molecular sieves in the fields of catalysis, biology fixation, adsorption, separation, preparation of nanomaterials and environmental protection, especially the desulfurization of gasoline prospects
摘要綜述了近幾年介孔分子篩在催化反應、生物固定吸附和分離、納米材料制備及環保等方面應用研究的進展，並對其在環保方面，尤其是汽油脫硫的應用前景做了展望。The selling engineer of our company has comprehensive professional knowledge to the production processes of users, before you order, we can sieve the medium according to users ' sieve machine type, production capacity, discharge demand of supplies factor is it analyse demand of you to come, so you can choose the rubber or the polyurethane ( pu ) to sift the surface material, we can also determine the grain size of sieving and sift the hole form accurately, this means screen mesh material of the company of square garden can produce the good economic benefits and social benefit
我公司的銷售工程師對于用戶的生產過程具有綜合的專業知識，在您定購前，我們可以根據用戶的篩機類型，篩分介質，生產能力，排出物料的要求等因素來分析您的要求，因此您可以選擇橡膠或聚氨酯（ pu ）篩面材料，我們還可以精確測定篩分粒度和篩孔狀，這就意味著方園公司的篩網材料可產生良好的經濟效益和社會效益。After the final washing and drying cycle, condition by laying the specimens separately on the screens or perforated shelves of a conditioning rack at 21 ? 1 ? c ( 70 ? 2 ? f ) and 65 ? 2 % rh for at least 4 hours before evaluation
完成最後一個洗滌和乾燥循環后，在評級前，把樣品分開放在篩子或有孔架上，在溫度70 ? 2 ? f ）和濕度65 ? 2 % rh下至少4小時。The regulation of acid catalytic property of molecular sieve can be realized via surface modification of mesoporous molecular sieve by means of introducing doping metals into skeleton or loading active species onto matrix during synthesizing precursor for mesoporous molecular sieve
在合成介孔分子篩的前驅物中摻雜其他金屬元素而將其引入骨架或將活性組分負載到介孔分子篩的基體上，可以實現對介孔分子篩表面進行表面修飾與改性，以調變分子篩表面的酸催化性能。分享友人
