Polyaminesakuyimira gulu la mankhwala achilengedwe omwe amadziwika ndi kukhalapo kwa magulu angapo a amino. Mankhwalawa, omwe nthawi zambiri amakhala opanda mtundu, okhuthala pamlingo wa pH wosalowerera. Mwa kuwonjezera ma amine osiyanasiyana kapena ma polyamine popanga, zinthu za polyamine zokhala ndi kulemera kosiyanasiyana kwa mamolekyulu ndi madigiri a nthambi zitha kupezeka kuti zigwirizane ndi magawo osiyanasiyana ochizira madzi.
Chifukwa chake, kugwiritsa ntchito ma polyamines kumakhudza mafakitale osiyanasiyana, kuphatikizapo kuwongolera madzi, kulekanitsa mafuta ndi madzi, kuchotsa mitundu, kukonza zinyalala, ndi kuuma kwa latex m'mafakitale a rabara. Mankhwalawa amagwiritsidwanso ntchito mumakampani opanga zokutira ndi mapepala, komanso m'mafakitale osiyanasiyana monga kukonza zinyalala zokonza nyama, monga zinyalala za zomera za nkhuku. Ma polyamines amapezeka m'magulu osiyanasiyana, okhala ndi kuchuluka kolimba kuyambira 50 mpaka 60%.
Ma polyamines ndi abwino kwambiri pophatikizana ndi ma colloidal dispersions, makamaka pakugwiritsa ntchito deposit control yokhudza zamkati, katundu, mawaya, kapena ma felts. Amachotsa bwino zinthu zachilengedwe ndi utoto kuchokera ku mitsinje yozungulira kapena yotulutsa madzi m'mafakitale a zamkati ndi mapepala. Komabe, kusankha mankhwala a polyamine otsika mtengo kwambiri kumafuna kuwunika magwiridwe antchito ogwirizana ndi chakudya kapena mtsinje womwe ukufuna chithandizo. Ma polyamines amatha kuperekedwa bwino kapena kuchepetsedwa mu mzere pamalo operekera chithandizo.
Zofunikira pa mlingo wa polyamines zimadalira kuopsa kwa vuto lomwe lilipo. Kuti muwongolere kuchuluka kwa pulp kapena stock, mlingo nthawi zambiri umakhala pakati pa 0.25 mpaka 2.5 kilogalamu ya polyamine pa tani imodzi ya pulp kapena stock (youma). Pothana ndi mavuto oyika pa nsalu yopangira, mlingo woyenera umakhala pakati pa 0.10 mpaka 1.0 milliliters pa mphindi imodzi pa phazi limodzi la m'lifupi mwa nsalu.
Kusunga bwino ndi kusamalira ma polyamines ndikofunikira kwambiri kuti apitirize kugwira ntchito bwino. Ma polyamines ayenera kusungidwa mkati mwa kutentha kwa 10–32°C. Kukumana ndi kutentha kwa kanthawi kochepa kunja kwa mtundu uwu nthawi zambiri sikuvulaza mankhwalawa. Ngati atazizira, ma polyamines ayenera kutenthedwa mpaka 26–37°C ndikusakaniza bwino musanagwiritse ntchito. Nthawi yosungira ma polyamines nthawi zambiri imafikira miyezi 12.
Mu ntchito zothandiza, kuphatikiza kwaPolyamine FlocculantKugwiritsa ntchito PAC (polyaluminum chloride) kwawonetsa kuti kuchotsa matope kumathandizira kwambiri pa ntchito zochizira madzi. Kuphatikiza kwa PAC/polyamine kumachepetsa bwino mlingo wa PAC, kumachepetsa kuchuluka kwa ma ion a aluminiyamu otsala m'madzi ochiritsidwa, komanso kumathandizira kuchotsa matope.
Posungira, ma polyamine ayenera kusungidwa m'zidebe zawo zoyambirira zomwe zili ndi mpweya woipa, kutali ndi kutentha, dzuwa. Kuti mudziwe malangizo atsatanetsatane okhudza momwe angagwiritsire ntchito komanso njira zodzitetezera, ogwiritsa ntchito ayenera kuwona chizindikiro cha mankhwala ndi Safety Data Sheet (SDS).
Ndife akatswiriwogulitsa ma polyamineszochizira mafakitale. Polyamine yogulitsidwa pakampani yathu ingagwire ntchito bwino kwa nthawi yayitali! Lumikizanani nafe! ( Imelo:sales@yuncangchemical.com )
