Kodi PolyDADMAC ndi poizoni: Vumbulutsani chinsinsi chake

PolyDADMAC, dzina la mankhwala lomwe limawoneka lovuta komanso losamvetsetseka, kwenikweni ndi gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku. Monga woyimira mankhwala a polima, PolyDADMAC imagwiritsidwa ntchito kwambiri m'magawo ambiri. Komabe, kodi mukumvetsa bwino momwe mankhwala ake amagwirira ntchito, mawonekedwe ake, ndi poizoni wake? Kenako, nkhaniyi ikupatsani kumvetsetsa kwakuya kwa PolyDADMAC.

Kapangidwe ka mankhwala a PolyDADMAC kamatsimikizira kake kapadera. Monga polyelectrolyte yamphamvu ya cationic, PolyDADMAC imaperekedwa ngati madzi okhuthala opanda mtundu kapena achikasu owala, kapena nthawi zina ngale zoyera. Kapangidwe kake kotetezeka komanso kopanda poizoni kamachititsa kuti igwiritsidwe ntchito kwambiri m'minda monga kukonza madzi, nsalu, kupanga mapepala, ndi minda yamafuta. Kuphatikiza apo, PolyDADMAC imasungunuka mosavuta m'madzi, siyaka moto, imakhala ndi mgwirizano wamphamvu, imakhala yolimba bwino m'madzi, siimva kusintha kwa pH, ndipo imakhala ndi kalembedwe kabwino kwambiri monga kukana chlorine. Nthawi zambiri imagwiritsidwa ntchito ngati flocculant ndipo nthawi zina imaperekedwa ndi algaecides. Zanenedwa kuti PDMDAAC imakhala ndi mphamvu yogwirizana ndi WSCP ndi poly-2-hydroxypropyl dimethylammonium chloride.

Kodi PolyDADMAC imagwira ntchito bwanji? PolyDADMAC ndi yamphamvu ndipo imagwira ntchito zosiyanasiyana m'magawo osiyanasiyana. Makamaka, pankhani yokonza madzi, PolyDADMAC imagwiritsidwa ntchito ngati flocculant ya cationic ndi coagulant. Kudzera mu kulowetsedwa ndi kulumikiza, imatha kuchotsa bwino zinthu zolimba ndi zonyansa zomwe zimapachikidwa m'madzi ndikukweza ubwino wa madzi. Mu makampani opanga nsalu, PolyDADMAC, monga chothandizira kukonza utoto wopanda formaldehyde, imatha kukonza utoto wa utoto ndikupanga nsalu kukhala zowala komanso zosatha. Pakupanga mapepala, PolyDADMAC imagwiritsidwa ntchito ngati chothandizira kunyamula zinyalala za anionic komanso chothandizira kuchiritsa cha AKD, zomwe zimathandiza kukonza ubwino wa mapepala ndikuchepetsa ndalama zopangira. Kuphatikiza apo, mumakampani opanga mafuta, PolyDADMAC imagwiritsidwa ntchito ngati chokhazikika cha dongo pobowola ndi chosinthira cationic cha acid fracturing mu injection yamadzi kuti iwonjezere kubwezeretsa mafuta m'munda.

Komabe, PolyDADMAC si chida chabwino kwambiri. Ngakhale ili ndi makhalidwe abwino kwambiri komanso malo ogwiritsira ntchito, muyenerabe kusamala za chitetezo mukaigwiritsa ntchito. Mwachitsanzo, muyenera kupewa kukhudzana mwachindunji ndi khungu ndi maso mukaigwiritsa ntchito kuti mupewe kuyabwa. Kuphatikiza apo, iyenera kutsekedwa ndikusungidwa mukaigwiritsa ntchito kuti mupewe kukhudzana ndi ma oxidant amphamvu ndikusungidwa pamalo ozizira komanso ouma. Ngakhale PolyDADMAC si poizoni, muyenerabe kuigwiritsa ntchito mosamala ndikutsatira malamulo achitetezo ndi njira zogwirira ntchito.

Mwachidule, PolyDADMAC, monga mankhwala a polima, imagwiritsidwa ntchito kwambiri m'magawo ambiri. Kapangidwe kake ka mankhwala ndi magwiridwe antchito ake abwino zimapangitsa kuti ikhale chisankho chabwino kwambiri pakutsuka madzi, nsalu, mapepala, ndi mafuta. Komabe, muyenerabe kusamala ndi nkhani zachitetezo mukamagwiritsa ntchito ndikutsatira malamulo ndi njira zoyenera zogwirira ntchito. Pokhapokha ngati tikutsimikiza kuti PolyDADMAC ikugwiritsidwa ntchito bwino komanso moyenera, ndi pomwe tingazindikire kuthekera kwake ndikubweretsa zosavuta komanso zabwino zambiri pamoyo wathu ndi ntchito yathu.
