Momwe mungazindikire mtundu wa ion wa polyacrylamide

Malinga ndi mtundu wa ion, polyacrylamide itha kugawidwa mu: anionic polyacrylamide ,cationic polyacrylamide komanso non-ionic polyacrylamide.

Kodi wopanga polyacrylamide amadziwika bwanji mtundu wa polyacrylamide ion:

Opanga Polyacrylamide amakhala ndi ma laboratories akatswiri. Kuphatikiza pakuyesa zaluso za zopangidwa tsiku ndi tsiku, ntchito ya labotale imafunikanso kuyesa zitsanzo zakunja. Nthawi zambiri, mukalandira mtundu wakunja, mtundu wa ion wazogulitsayo uyenera kuzindikiridwa kaye. Ndiye mungasiyanitse bwanji mtundu wa ion? Yankho lake ndi: zisonyezo zaukadaulo zakuyang'ana zitsanzo zakunja. Anionic polyacrylamide ndi non-ionic polyacrylamide amadziwika pozindikira kuchuluka kwa hydrolysis. Mlingo wa hydrolysis wa anionic polyacrylamide ndi pafupifupi 25, ndipo kuchuluka kwa hydrolysis ya non-ionic polyacrylamide ili pafupifupi 5. Cationic polyacrylamide imasiyanitsidwa pozindikira digiri ya ion, ndipo kuchuluka kwa ion kwa zopangidwa ndi ufa wouma nthawi zambiri kumasintha pakati pa 10-60.

Momwe mungazindikire mtundu wa polyacrylamide ion kudzera poyesa kosavuta:

Momwe mungasiyanitsire mtundu wa ion wa polyacrylamide pomwe ogwira nawo ntchito ali patsamba logulitsa pambuyo pake kapena alibe zida zoyesera? Choyamba, tiyenera kukhala ndi zitsanzo za anionic polyacrylamide ndi cationic polyacrylamide, ndikusungunula zinthu ziwirizi padera kuti zigwiritsidwe ntchito. Kenako sungunulani chinthu chomwe chikufunika kuzindikira mtundu wa ion, ndikuwasiyanitsa ndi mayankho a yin ndi yang. Thirani anionic polyacrylamide solution yomwe yasungunuka mu njira yothetsera mankhwala kuti ayesedwe. Ngati pali ma flocs oyera ambiri, zikutanthauza kuti mtundu woyesedwayo ndi cationic polyacrylamide. Ngati palibe zomwe angachite, zikutanthauza kuti si ionic kapena anionic. Kenako zindikirani ndi yankho la cationic polyacrylamide, kuchuluka kwa ma flocs kumawonetsa kuti mankhwala omwe adayesedwa ndi ionic polyacrylamide, ndipo ma flocs ambiri akuwonetsa kuti choyesedwacho ndi anionic polyacrylamide.

Kufunika kodziwitsa mtundu wa polyacrylamide ion:

Mukakhala simukudziwa chomwe chikugwiritsidwa ntchito pophulika pamalopo, kuzindikira mtundu wa polyacrylamide ion kumatha kuthandiza ogwiritsa ntchito mwachangu kuwonera mitundu ndikupeza zinthu zomwe zikufanana ndi madzi akuda pamalopo mwachangu.

Phunzirani kuzindikira mtundu wa polyacrylamide ion, kuti ogwiritsa ntchito amvetse bwino mankhwalawo, agwiritse ntchito malonda ndi zinthu zabwino, azindikire, komanso chenjerani ndi ogulitsa oyipa omwe amanyenga ogula
