1、選擇聚氨(an)酯篩網時首先看篩孔(kong)是否均(jun)勻(yun)(yun):優質聚氨(an)酯篩片篩孔(kong)均(jun)勻(yun)(yun)且合乎標準,公差(cha)范圍小。
2、看聚氨酯篩網(wang)的開孔(kong)(kong)率(lv)(lv)。開孔(kong)(kong)率(lv)(lv)是(shi)影響篩分(fen)效率(lv)(lv)的最(zui)直接因素:聚氨酯篩片的篩孔(kong)(kong)數量(liang)越(yue)多開孔(kong)(kong)率(lv)(lv)越(yue)高,篩分(fen)效率(lv)(lv)和產量(liang)就越(yue)高。
3、看聚氨(an)酯(zhi)(zhi)篩(shai)(shai)網的連(lian)(lian)(lian)接:聚氨(an)酯(zhi)(zhi)篩(shai)(shai)片(pian)的連(lian)(lian)(lian)接方式直接影響(xiang)篩(shai)(shai)分效率。河北冀衡礦山研發飛(fei)發的聚氨(an)酯(zhi)(zhi)篩(shai)(shai)片(pian) 有自動連(lian)(lian)(lian)接裝置的篩(shai)(shai)片(pian),連(lian)(lian)(lian)接簡便(bian)(bian)省時,拆裝更(geng)為方便(bian)(bian),便(bian)(bian)于(yu)縮短初裝工時和使用中局部篩(shai)(shai)片(pian)更(geng)換(huan)時間,從而(er)提(ti)高了生產效率。 要求聚氨(an)酯(zhi)(zhi)篩(shai)(shai)網達到相互(hu)之(zhi)間連(lian)(lian)(lian)接緊(jin)密,不漏(lou)礦,以保證品(pin)位。
4、優質聚氨酯篩(shai)網要(yao)(yao)剛柔適中:實際生產(chan)中要(yao)(yao)求聚氨酯篩(shai)片要(yao)(yao)有很強的彈性,以便確(que)保生產(chan)中不塌腰;聚氨酯篩(shai)網又要(yao)(yao)有一定(ding)的韌性,保證篩(shai)片不易碎。
5、選擇聚(ju)氨(an)(an)酯(zhi)篩網時要看其(qi)外(wai)觀:外(wai)觀聚(ju)氨(an)(an)酯(zhi)篩片(pian)表面是否(fou)精致,篩片(pian)是否(fou)平整,看聚(ju)氨(an)(an)酯(zhi)篩片(pian)色(se)相(xiang)是否(fou)純正,有沒(mei)有斷條、毛(mao)刺、缺(que)料(liao)、混料(liao)、密縫等現(xian)象(xiang)。
6、具有良好的(de)低溫性(xing)能。
7、耐輻射(she)性(xing)(xing)能(neng)。聚氨(an)酯(zhi)耐高能(neng)射(she)線的性(xing)(xing)能(neng)很好,在(zai)10-10戈輻射(she)劑量下仍(reng)具有滿意的使用(yong)性(xing)(xing)能(neng)。
