ZLS-100<\/span><\/span>型紙張過濾速度測定儀<\/span> <\/p> <\/span>

1. 用途和工作原理<\/span> <\/p>

   本儀器適用于具有一定濕強(qiáng)度的過濾紙及過濾紙板濾水速度的測定，但不能用于經(jīng)樹臘加工，或其表面不親水或不完全親水的過濾紙和過濾紙板濾水速度的測定。<\/span> <\/p>

   儀器的工作原理是在紙樣兩面的壓蓋為<\/span>1Kpa<\/span>（即<\/span>100mm<\/span>水柱）條件下，透過直徑<\/span>35.7mm<\/span>（面積<\/span>10cm?<\/span><\/span>）的紙樣流出<\/span>100ml<\/span>或<\/span>50ml<\/span>水所需的時(shí)間，時(shí)間以秒表示。<\/span> <\/p>

   對水質(zhì)的要求：在<\/span>20°C<\/span>時(shí)水質(zhì)應(yīng)符合導(dǎo)電率為（<\/span>3.2<\/span>—<\/span>4.4<\/span>）<\/span>×10^{7<\/sup>ms/m<\/span>的自來水或含<\/span>0.02%Nacl<\/span>的蒸餾水或去離子水經(jīng)<\/span>0.8u<\/span>濾膜或與之相當(dāng)?shù)臑V紙濾過并用加熱或真空脫氣后的水。<\/span> <\/p> <\/li>}

2. 基本參數(shù)<\/span> <\/p> <\/li><\/ol> <\/span>

   1. 測定濾紙厚度范圍<\/span>0.10<\/span>～<\/span>3.00mm<\/span> <\/p> <\/li>

   2. 試驗(yàn)面積：<\/span>10<\/span>±<\/span>0.05cm^{2<\/sup><\/span> <\/p> <\/li>}

   3. 夾環(huán)內(nèi)徑：<\/span>φ35.7mm<\/span> <\/p> <\/li>

   4. 夾環(huán)外徑：<\/span>φ50mm<\/span> <\/p> <\/li>

   5. 儀器外形尺寸（長<\/span>×<\/span>寬<\/span>×<\/span>高）<\/span>330×290×770<\/span> <\/p> <\/li>

   6. 儀器凈重：約<\/span>15kg<\/span> <\/p> <\/li> <\/ol><\/ol> <\/span>
