Mawu Ofunika: Poly dimethyl diallyl ammonium chloride, PDMDAAC, PDADMAC, PolyDADMAC
Mu dziko lokongola la mankhwala a tsiku ndi tsiku, zosakaniza zambiri, monga ulusi wosaoneka, zimaluka mwakachetechete chithunzi chokongola cha zochita zathu za tsiku ndi tsiku zosamalira khungu.Poly dimethyl diallyl ammonium chloride (PDADMAC)ndi chinthu choterocho—ngakhale kuti sichimawonekera mwachindunji pa zilembo zodzikongoletsera, chimaphatikizidwa kwambiri mu zinthu zosamalira tsitsi mu mawonekedwe a polima, zomwe zimapangitsa kuti tsitsi ndi khungu zikhale zosalala. Ndiye, kodi chinthu ichi ndi chotetezekadi kukhudzana nacho? Yankho lake lili mu ubale wake wobisika ndi zodzoladzola.
Kapangidwe ka mankhwala ka Poly dimethyl diallyl ammonium chloride kamapatsa "kugwirizana" kwapadera. Monga cationic polymer, imakhala ndi mphamvu yabwino ndipo imatha kunyamula mosavuta ulusi kapena tinthu tating'onoting'ono tomwe tili ndi mphamvu yoipa. Mu makampani opanga zodzoladzola, izi zimagwira ntchito zothandiza: ikawonjezedwa ku shampu, imachepetsa mphamvu yamagetsi yopangidwa ndi kukangana, zomwe zimapangitsa tsitsi kukhala losalala komanso losavuta kugwiritsa ntchito m'malo mozizira; mu shawa gel, imagwira ntchito ngati filimu yoteteza yosaoneka, kuchepetsa kutaya chinyezi ndikusiya khungu likumva losalala. Izi si zamatsenga, koma zimachokera ku kusinthasintha ndi kusungunuka kwa madzi kwa unyolo wake wa mamolekyu - umafalikira mwachangu m'madzi, ndikupanga yankho lofanana lomwe limaphimba tsitsi lililonse kapena khungu popanda kusiya kumverera komata. Tangoganizirani kuwala kwa tsitsi lanu mutasamba; makamaka chifukwa cha ntchito yopanda phokoso ya Poly dimethyl diallyl ammonium chloride.
Komabe, "kulumikizana kotetezeka" kwaPolyDADMACsikuti ndi kopanda malire. Kusamalira zosakaniza mu zodzoladzola kuli ngati kulinganiza bwino zinthu, komwe kumafuna mphamvu komanso kupewa zoopsa.PolyDADMACLokha ndi lokhazikika, silikhudzidwa ndi kusintha kwa pH, ndipo siliyaka moto, zomwe zimapereka chitsimikizo choyambira cha kugwiritsidwa ntchito kwake mu mankhwala a tsiku ndi tsiku. Koma mfundo yaikulu ili mu nkhani ya "ma monomers ake otsala." Pa nthawi ya polymerization, kuchuluka kwa ma monomers a acrylamide sikungagwire ntchito mokwanira, ndipo acrylamide yokha ikhoza kukwiyitsa. Chifukwa chake, kuwongolera mwamphamvu kuchuluka kwa zotsalira ndikofunikira kuti pakhale chitetezo. Mwachitsanzo, mu shampu kapena mafuta, kuchuluka kwa Poly dimethyl diallyl ammonium chloride komwe kumawonjezeredwa kuyenera kulamulidwa bwino kuti zitsimikizire kuti kuchuluka kwa monomer mu mankhwalawa kuli pansi pa malire otetezeka, kupewa kulemetsa khungu lofooka. Kuyang'anira mosamala kumeneku kumasinthaPolyDADMACkuchoka pa zinthu zopangira mafakitale kupita ku chinthu chosamalira tsiku ndi tsiku chomwe ogula angagwiritse ntchito ndi mtendere wamumtima.
Kuchokera pamalingaliro okulirapo, "chitetezo cha kukhudzana" kwaPolyDADMACimaonekeranso chifukwa cha ubwino wake pa chilengedwe. Imasungunuka mosavuta m'madzi, siimapanga ma gels, ndipo imalimbana ndi ma chloride ions, zomwe zikutanthauza kuti sizingatheke kuti isunge kapena kutulutsa zinthu zovulaza m'madzi otayidwa kapena m'malo achilengedwe. Poyerekeza ndi zina zowonjezera mankhwala,PolyDADMACimawola bwino, zomwe zimachepetsa kuwonongeka kwa chilengedwe kwa nthawi yayitali. Tikamalankhula za "kukhudzana mwachindunji," sitikutanthauza kukhudzana kwakanthawi ndi khungu kapena tsitsi, komanso tikutanthauza kukhudzana kwake konse ndi chilengedwe - kuyambira kupanga mpaka kutaya, nzeru za kapangidwe kakePolyDADMACnthawi zonse imatsamira pa chiopsezo chochepa komanso kugwirizana kwakukulu. Pomaliza,PolyDADMACSizoletsedwa "kukhudzana mwachindunji," koma m'malo mwake, kudzera mu njira yasayansi komanso malamulo okhwima, yakhala ngati chitetezo chofunikira komanso chofatsa mu zodzoladzola. Monga wojambula wosaoneka, imagwiritsa ntchito maburashi kuti iwonetse chithunzi chogwirizana cha kukongola ndi chitetezo. Nthawi ina mukasangalala ndi tsitsi losalala kapena khungu lonyowa, kumbukirani zomwe nzeru za mankhwalazi zimachita - zomwe zimapangitsa chisamaliro cha tsiku ndi tsiku kukhala chogwira ntchito komanso chotetezeka.
