標準篩質量好壞(huai)的辨別(bie)技(ji)巧?
標(biao)準(zhun)篩(shai)(shai)(shai)(shai)分(fen)為(wei)標(biao)準(zhun)分(fen)樣篩(shai)(shai)(shai)(shai)、化工(gong)(gong)專用(yong)(yong)篩(shai)(shai)(shai)(shai)、土壤專用(yong)(yong)篩(shai)(shai)(shai)(shai)、石(shi)(shi)子專用(yong)(yong)篩(shai)(shai)(shai)(shai)、砂(sha)子專用(yong)(yong)篩(shai)(shai)(shai)(shai)、水(shui)泥專用(yong)(yong)篩(shai)(shai)(shai)(shai)、瀝青專用(yong)(yong)篩(shai)(shai)(shai)(shai)、煤樣專用(yong)(yong)篩(shai)(shai)(shai)(shai)、冶金(jin)礦石(shi)(shi)檢驗(yan)篩(shai)(shai)(shai)(shai)等 。標(biao)準(zhun)篩(shai)(shai)(shai)(shai)的篩(shai)(shai)(shai)(shai)網(wang)(wang)材料 ，每種的特點和應(ying)(ying)用(yong)(yong)范圍(wei)各不相(xiang)同：金(jin)屬絲(si)編織網(wang)(wang)(應(ying)(ying)用(yong)(yong)廣泛網(wang)(wang)孔(kong)(kong)從(cong)2.36毫米到(dao)0.02毫米之間只有(you)方孔(kong)(kong)網(wang)(wang))、沖(chong)孔(kong)(kong)板篩(shai)(shai)(shai)(shai)網(wang)(wang)(主要應(ying)(ying)用(yong)(yong)于(yu)大(da)網(wang)(wang)孔(kong)(kong)，有(you)圓(yuan)孔(kong)(kong)和方孔(kong)(kong)兩種網(wang)(wang)孔(kong)(kong)從(cong)0.2到(dao)幾百毫米)、電(dian)成型篩(shai)(shai)(shai)(shai)網(wang)(wang)(主要用(yong)(yong)于(yu)高精度(du)(du)的場合，可以做(zuo)到(dao)每個網(wang)(wang)孔(kong)(kong)都在平均(jun)誤差范圍(wei)內)。作為(wei)標(biao)準(zhun)篩(shai)(shai)(shai)(shai)的專業生(sheng)產廠(chang)家必須(xu)具(ju)(ju)備工(gong)(gong)具(ju)(ju)顯微鏡和投影(ying)儀，工(gong)(gong)具(ju)(ju)顯微鏡是用(yong)(yong)來檢查網(wang)(wang)孔(kong)(kong)的精度(du)(du)，采用(yong)(yong)算(suan)數平均(jun)值(zhi)方法。
標準(zhun)(zhun)篩(shai)有嚴格(ge)的(de)網(wang)孔(kong)尺(chi)寸規定，標準(zhun)(zhun)篩(shai)是用(yong)網(wang)孔(kong)尺(chi)寸表示每(mei)個篩(shai)子的(de)規格(ge)。那么，怎樣才能購買到(dao)即合適(shi)又(you)標準(zhun)(zhun)的(de)標準(zhun)(zhun)篩(shai)?
我(wo)們接(jie)到(dao)很多(duo)客戶咨詢標(biao)準篩(shai)，但是(shi)我(wo)們的(de)客戶也有(you)說到(dao)我(wo)們的(de)產品價(jia)格方面(mian)有(you)點高，俗話說“一(yi)分價(jia)錢，一(yi)份(fen)貨，”我(wo)們怎樣(yang)才(cai)能更好的(de)辨別試驗(yan)篩(shai)的(de)做(zuo)工及個方面(mian)的(de)好與壞那?首(shou)先(xian)先(xian)看一(yi)下圖(tu)片對比(bi)：
1、篩框(kuang)是否是一次成(cheng)型，無(wu)焊縫，美觀，不夾(jia)料。
2、篩框是否是0.63mm 304不銹(xiu)鋼材(cai)質。
3、篩(shai)網是否緊致(zhi)，平整。
4、篩網(wang)的網(wang)孔是(shi)否符合GB/T6003.1-1997標準。
所以購買標準篩(shai)一定要(yao)選擇正規廠(chang)家，立友機(ji)械擁有十幾年的生(sheng)(sheng)產(chan)經(jing)驗(yan)，生(sheng)(sheng)產(chan)的標準篩(shai)完全符合國家標準，所采用(yong)的篩(shai)網是經(jing)嚴格按照GB6003.1-1997標準生(sheng)(sheng)產(chan)，并經(jing)工(gong)具(ju)顯微鏡選取。我(wo)公司對(dui)(dui)規格采用(yong)網孔/絲徑(jing)的標記方法(因目數(shu)是相對(dui)(dui)單(dan)位，目數(shu)指1英寸25.4毫米長度上孔和絲的數(shu)量。同(tong)樣的目數(shu),絲徑(jing)不同(tong)，孔也不同(tong))。廣泛用(yong)于磨料(liao)，地堪(kan)，冶(ye)金，藥典，化工(gong)建材等行業(ye)顆粒(li)物料(liao)的精確篩(shai)分和粒(li)度檢(jian)測。
