Kugwiritsa ntchito polyacrylamide mumakampani opanga mapepala --Dispersant, flocculant

Wosweka, flocculant

The polyacrylamide dispersant mu makampani pepala makamaka cationic Polyacrylamide ndi ndi otsika maselo kulemera.Chifukwa unyolo wake wa mamolekyu uli ndi magulu a carboxyl, umakhala ndi zotsatira zobalalika pa ulusi woyipitsidwa moyipa, umatha kukulitsa kukhuthala kwa zamkati, umathandizira kuyimitsidwa kwa ulusi, ndipo ukhoza bwino Imatha kupangitsa kuti pepala likhale lofanana, ndipo ndilabwino kwambiri. dispersant kwa ulusi wautali.Amphoteric Polyacrylamide ntchito ngati flocculant kwa madzi mankhwala mu makampani pepala.Gulu lake la amide limatha kupanga zomangira za haidrojeni ndi zinthu zambiri m'madzi otayidwa, kotero zimatha kukopa tinthu tating'onoting'ono tomwe timamwazikana m'madzi ndikuwaphatikiza.Imathandizira kukhazikika ndi kusefera kwa ma particulates.Poyerekeza ndi flocculants ena inorganic, amphoteric Polyacrylamide ali ubwino wa mitundu wathunthu, mowa pang'ono kupanga, kudya okhazikika liwiro, sludge zochepa kupanga, ndi losavuta pambuyo mankhwala, etc., amene angakwaniritse zofunika zosiyanasiyana mankhwala amadzi oipa.

Mwachidule, polyacrylamide imagwira ntchito yofunika kwambiri pamakampani opanga mapepala.Ikhoza kugwiritsidwa ntchito ngati wothandizira mapepala, kulimbikitsa wothandizira, dispersant, fyuluta zothandizira, etc. Cholinga chake ndi kupititsa patsogolo kufanana kwa pepala, kupititsa patsogolo bwino ndi mphamvu ya pepala, komanso kupititsa patsogolo kusungirako kwa fillers ndi ulusi wabwino, kuchepetsa Kuchepetsa kutayika kwa zopangira, kukonza bwino kusefa komanso kuchepetsa kuwononga chilengedwe.

CPAM imagwiritsidwa ntchito ngati chowonjezera chothandizira, kudzera pakupanga ma ionic zomangira pakati pa ma cations ndi anions pamitsempha, imatha kudyedwa pamitsempha yamkati, pomwe magulu a amide amaphatikizana ndi magulu a hydroxyl pa ulusi kuti apange zomangira za haidrojeni, zomwe zimakulitsa. mphamvu yomangira pakati pa ulusi.Wonjezerani mphamvu zamapepala.Zotsatira zowonjezera za APAM kuphatikiza rosin ndi aluminiyamu sulphate zimathanso kulimbitsa bwino zikagwiritsidwa ntchito mu zamkati, koma mphamvu yolimbikitsira ya APAM idzachepa ndi kuchuluka kwa zodzaza.
