Kodi ndimasankha bwanji mtundu wa polyacrylamide?

Polyacrylamide. Amagwiritsidwa ntchito makamaka pokonza madzi. Mukamasankha, mitundu yosiyanasiyana ya madzi otayika ikhoza kusankha mitundu yosiyanasiyana. Muyenera kusankha Pam Wamkumphu molingana ndi mawonekedwe a chimbudzi chanu. Nthawi yomweyo, muyenera kufotokozeranso momwe ma polyacrylamide adzawonjezeredwa ndipo cholinga chomwe mukufuna kukwaniritsa pogwiritsa ntchito.

Zizindikiro zaukadaulo za polyacrylamide nthawi zambiri zimaphatikizapo kulemera kwa ma hydrolysis, ionicty, zowoneka bwino, zowoneka bwino.

1. Kulemera kwa molecular / mafayilo

Polyacrylamide ali ndi zolemera zosiyanasiyana, kuyambira kotsika mpaka kwambiri. Kulemera molecular kumakhudza magwiridwe antchito a ma polima pamapulogalamu osiyanasiyana. Kuchuluka kwa ma polyacrramide nthawi zambiri kumakhala kothandiza kwambiri pokonzanso chifukwa maunyolo awo a polymer amakhala atatali ndipo amatha kulumikiza ti ti ti ti ti ti ti ti ti ti tinthu tating'onoting'ono.

Makulidwe a Pam yankho la Pam ndilokwera kwambiri. Ma Ioniza atakhazikika, chizinga chachikulu cha kulemera kwa Polyacrylamide, mafayilo ambiri yankho lake. Izi ndichifukwa choti ma a Macromolecular a Polyacrylamide ndi yayitali komanso yoonda, ndipo kukana koyenda mu yankho ndi lalikulu kwambiri.

2. Mulingo wa hydrolysis ndi ionicity

Ma Ionicity a Pam ali ndi chidwi chachikulu pa ntchito yake, koma mtengo wake woyenera umatengera mtundu ndi chikhalidwe cha zinthu zomwe zachitidwazo, ndipo pali mfundo zosiyanasiyana zosiyanasiyana. Mphamvu ya Ionic yomwe idachitidwayo ndi yokwera (yochulukirapo inorganiation), ma ioniclence a Pam iyenera kukhala yapamwamba, apo ayi iyenera kukhala yotsika. Nthawi zambiri, kuchuluka kwa anion kumatchedwa digiri ya hydrolysis, ndipo kuchuluka kwa ion nthawi zambiri kumatchedwa kuti concation.

Momwe Mungasankhire PolyacrlamideZimatengera kuchuluka kwa ma cokinods ndikuimitsa mathithi amadzi. Pambuyo kumvetsetsa zizindikiro zapamwambazi pamwambapa, momwe mungasankhire Pampano woyenera?

1. Mvetsetsani gwero la chimbudzi

Choyamba, tiyenera kumvetsetsa komweko, chilengedwe, kapangidwe kake, zina zolimba, zina zolaula.

Nthawi zambiri, timalankhula za polyacryamide imagwiritsidwa ntchito pochiza sludge, ndipo anionec polyacrlamide imagwiritsidwa ntchito pochiza sludge. Pamene pH imakhala yokwera, yophunzitsira polyacrlamide sayenera kugwiritsidwa ntchito, ndipo ikakhala, iononec polyacrlamide sayenera kugwiritsidwa ntchito. Acidity acidity imapangitsa kuti ikhale yoyenera kugwiritsa ntchito anionic polyacrylamide. Zomwe zili zolimba za sludge ndizokwera, kuchuluka kwa polyacrylamide ntchito ndizambiri.

2. Kusankha kwa Ioniclity

Kwa sludge yomwe imafunikira kuchepetsedwa mankhwala onyansa, mutha kusankha maluwa ndi ma ioniclants osiyanasiyana pakuyesa kwa polyacrlamide kwambiri, komwe kungakwaniritse mphamvu yabwino ndikuchepetsa mlingo, kusunga mtengo.

3. Kusankha kwa kulemera kwa masele

Nthawi zambiri, zochulukitsa zolemera za zinthu za polyacrylamide, zikugwiritsidwa ntchito, koma pogwiritsa ntchito, kuchuluka kwa zochulukitsa kwa malonda, ndibwino kugwiritsa ntchito ntchito. Pogwiritsa ntchito mwatsatanetsatane, kulemera koyenera kwa polyacrylamide kuyenera kutsimikiza malinga ndi makampani enieni ogwiritsira ntchito, madzi abwino komanso zida zamankhwala.

Mukagula ndikugwiritsa ntchito Pam kwa nthawi yoyamba, tikulimbikitsidwa kupereka zochitika za chimbudzi chokhala ndi malo oyandikana nawo, ndipo tikupangira mtundu woyenera kwa inu. Ndi zitsanzo za makalata oyeserera. Ngati muli ndi zokumana nazo zambiri mu chithandizo chanu, mutha kutiuza zofunikira zanu, magawo ogwiritsa ntchito, ndi njira, kapena amatipatsa zitsanzo za Pam yomwe mukugwiritsa ntchito, ndipo tidzakufananitsani ndi polyacrramide.
