Kodi PolyDADMAC ndi yapoizoni: Vumbulutsani chinsinsi chake?

Zithunzi za PolyDADMAC, dzina la mankhwala looneka ngati locholoŵana ndi losamvetsetseka, kwenikweni ndi mbali yofunika ya moyo wathu watsiku ndi tsiku. Monga woimira mankhwala polima, PolyDADMAC chimagwiritsidwa ntchito m'madera ambiri. Komabe, kodi mumamvetsetsa bwino za mankhwala ake, mawonekedwe ake, komanso kawopsedwe? Kenako, nkhaniyi ikupatsani kumvetsetsa mozama za PolyDADMAC.

The mankhwala katundu wa PolyDADMAC kudziwa katundu wake wapadera. Monga amphamvu cationic polyelectrolyte, PolyDADMAC amaperekedwa ngati colorless chikasu maonekedwe viscous madzi, kapena nthawi zina ngale zoyera. Makhalidwe ake otetezeka komanso opanda poizoni amawapangitsa kuti azigwiritsidwa ntchito kwambiri m'magawo monga kuthira madzi, nsalu, kupanga mapepala, ndi minda yamafuta. Kuonjezera apo, PolyDADMAC imasungunuka mosavuta m'madzi, yosayaka, imakhala ndi mgwirizano wamphamvu, kukhazikika kwa hydrolytic, sikukhudzidwa ndi kusintha kwa pH, ndipo imakhala ndi zinthu zabwino kwambiri monga kukana kwa chlorine. Nthawi zambiri amagwiritsidwa ntchito ngati flocculant ndipo nthawi zina amathiridwa ndi algaecides. Zimanenedwa kuti PDMDAAC ili ndi synergistic effect ndi WSCP ndi poly-2-hydroxypropyl dimethylammonium chloride.

Kodi PolyDADMAC imayamba bwanji?

PolyDADMAC ndi yamphamvu ndipo imagwira ntchito zosiyanasiyana m'magawo osiyanasiyana. Makamaka, pankhani ya chithandizo chamadzi, PolyDADMAC imagwiritsidwa ntchito ngati cationic flocculant ndi coagulant. Kudzera mu adsorption ndi mlatho, imatha kuchotsa zolimba zoyimitsidwa ndi zonyansa m'madzi ndikuwongolera madzi abwino. M'makampani opanga nsalu, PolyDADMAC, monga formaldehyde-free color-fixing agent, imatha kusintha mawonekedwe a utoto wa utoto ndikupanga nsalu kukhala zowala komanso zosatha kuzirala. Popanga mapepala, PolyDADMAC imagwiritsidwa ntchito ngati chophatikizira zinyalala za anionic ndi AKD kuchiritsa accelerator, kuthandiza kukonza pepala komanso kuchepetsa ndalama zopangira. Kuphatikiza apo, m'makampani amafuta, PolyDADMAC imagwiritsidwa ntchito ngati chokhazikika chadongo pobowola komanso chosinthira cha acidic fracturing cationic modifier mu jakisoni wamadzi kuti chiwongolere kumunda wamafuta.

Komabe, PolyDADMAC si chipolopolo chasiliva. Ngakhale ili ndi zinthu zambiri zabwino kwambiri komanso malo ogwiritsira ntchito, muyenerabe kusamala zachitetezo mukachigwiritsa ntchito. Mwachitsanzo, kukhudzana mwachindunji ndi khungu ndi maso kuyenera kupewedwa panthawi yogwiritsira ntchito pofuna kupewa kupsa mtima. Pamwamba pa izo, ziyenera kusindikizidwa ndikusungidwa mukatha kugwiritsa ntchito kuti zisakhudzidwe ndi okosijeni amphamvu ndikusungidwa pamalo ozizira komanso owuma. Ngakhale PolyDADMAC ilibe poizoni, muyenerabe kuigwiritsa ntchito mosamala ndikutsata malamulo otetezeka ndi njira zogwirira ntchito.

Pomaliza, PolyDADMAC, monga mankhwala a polima, amagwiritsidwa ntchito kwambiri m'magawo ambiri. Kapangidwe kake kapadera kamankhwala komanso magwiridwe antchito abwino kwambiri zimapangitsa kuti ikhale chisankho chabwino chopangira madzi, nsalu, mapepala, ndi malo opangira mafuta. Komabe, mukuyenerabe kusamala zachitetezo mukamagwiritsa ntchito ndikutsata malamulo oyenera ndi njira zogwirira ntchito. Pokhapokha poonetsetsa kuti PolyDADMAC ndiyogwiritsa ntchito motetezeka komanso moyenerera tingathe kuzindikira kuthekera kwake ndikubweretsa kumasuka ndi zopindulitsa pa moyo wathu ndi ntchito.
