Company was set up in 1997 , as a high - tech enterprise with ability of reserch , development and manufacture , it was set up for limited company in 2006 , and has passed iso9001 : 2000 quality adminis - tration system certification . company have professional works , excellent process equipments , perfect checkout apparatus , and produces all sorts of premanent magnetic chuch , electro magnetic chuch , rectiffication ` s manipulator and magnetic removal with adwantages of advanced designment , long longevity , big suction and small remanence . the quality has passed the certification of china quality test association and china quality indemnify center 公司成立于1997年,是一家集科研開發生產為一體的高科企業, 2006年組建為有限公司,并通過iso9001 : 2000質量體系認證,公司擁有專業的技術人員,精良的加工設備,完善的檢測儀器,所生產的各種永磁吸盤、電磁吸盤、整流控制器、退磁器等磁性工具,具有設計先進、壽命長、吸力大、剩磁小等特點,質量通過中國質量檢驗協會,中國質量保障中心認證。

The finer the grain is , the higher the magnetic properties are , such as the improvement of coercivity . according to the theory of remanence , the intensity of remanence is in direct proportion to the density of magnet and ms . the improvement of remanence resulted from the interaction of density of magnet and ms , but the ms took the more important role 究其原因:晶粒的細化可以提高磁體的矯頑力;而根據剩磁的理論公式,剩磁與磁體密度和飽和磁化強度成正比,剩磁的提高是磁體密度和飽和磁化強度的提高的綜合效果,但其中飽和磁化強度的提高占主導地位。

Being added an anti - phase compensating winding , this device , which is placed between high voltage line and first insulator , makes the synthesized magnetic field in magnetic core reach a dynamic balance , and thus solves the problems from remanence and assures the measurement accuracy 其漏電流傳感器增加一個反相的補償線圈,使得電流傳感器磁芯內的合成磁場達到動態平衡,解決了由于剩磁而帶來的問題,保證了測量精度。

Sem shows that the composite ferrite is like cotton and displays one by one , their diameters are about 50nm . vsm measurement in the strong magnetic field reveals that its coercive force and remanence are zero , that is , the product is supermagnetic one Sem表明復合型鐵氧體呈“棉花狀” ,顆粒排列緊湊,粒徑在50nm左右;磁滯回線顯示該鐵氧體的矯頑力和剩磁均為零,證明其為超順磁物質。

Lastly , calculating the magnet performance using theoretical formulation , which expresses the relationship of the external magnetic field and remanence of the magnet , can tell the type of unknown magnet 另外,通過對磁體國防科學技術大學研究生院學位論文表面場的測量,并結合理論公式可以判斷未知磁體類型。
