Momwe mungasinthire bwino ntchito yopanga mapepala kudzera mu polyacrylamide

Polyacrylamidendi chowonjezera chomwe chimagwiritsidwa ntchito kwambiri pamakampani opanga mapepala. Polyacrylamide (PAM), monga polima sungunuka madzi, ali kwambiri flocculation, thickening, kubalalitsidwa ndi katundu zina. Idzagwiritsidwa ntchito munjira zingapo zosiyanasiyana ndi ntchito zosiyanasiyana. Pamakampani opanga mapepala, PAM imagwira ntchito yofunika kwambiri. Zabweretsa phindu lalikulu pazachuma kumakampani opanga mapepala powongolera zinthu zamkati ndikuwonjezera magwiridwe antchito a makina amapepala. Nkhaniyi ifotokoza mwatsatanetsatane kagwiritsidwe ntchito ka polyacrylamide popanga mapepala komanso momwe zimakhudzira kukonza bwino kwa kupanga.

Basic katundu ndi ntchito za Polyacrylamide

Polyacrylamide ndi mkulu maselo polima kuti akhoza kugawidwa mu nonionic, anionic, cationic ndi amphoteric mitundu malinga ndi katundu katundu. PAM ikasungunuka m'madzi, ndipo kapangidwe kake ka molekyulu yayitali kamathandiza kuti ikhale ndi ntchito zabwino kwambiri monga flocculation, thickening, retention help, and filtration help. Pamakampani opanga mapepala, polyacrylamide imagwiritsidwa ntchito kwambiri pazinthu izi:

1. Thandizo posungira:

Mamolekyu a PAM ali ndi unyolo wautali ndipo amatha kujambulidwa pamwamba pa ulusi ndi zodzaza kuti apange milatho. Potero kukonza kasungidwe ka ma fillers ndi ma fiber pa intaneti yamapepala. Chepetsani kutaya kwa CHIKWANGWANI m'madzi oyera ndikuchepetsa kuwonongeka kwazinthu zopangira. Powonjezera kuchuluka kwa kusungitsa kwa zodzaza ndi ulusi, mawonekedwe a pepala monga kusalala, kusindikiza, ndi mphamvu zitha kuwongoleredwa.

2. Zothandizira zosefera:

Limbikitsani kutulutsa madzi kwa zamkati, kufulumizitsa kusefera kwamadzi ndikuchepetsa kugwiritsa ntchito mphamvu.

3. Flocculant:

Kufulumizitsa kutaya madzi m'thupi: PAM imatha kuyandama bwino tinthu tating'ono, zodzaza ndi zinthu zina zoyimitsidwa mu zamkati kupanga tinthu tating'onoting'ono, kufulumizitsa kukhazikika kwamatope ndi kutaya madzi m'thupi, ndikuchepetsa mtengo wamankhwala amatope.

Limbikitsani ubwino wa madzi: PAM imatha kuchotsa zolimba zoyimitsidwa ndi zinthu zamoyo m'madzi onyansa, kuchepetsa BOD ndi COD m'madzi onyansa, kupititsa patsogolo madzi abwino, ndi kuchepetsa kuwonongeka kwa chilengedwe.

4. Wobalalitsa:

Pewani kuphatikizika kwa ulusi: PAM imatha kupewa kuphatikizika kwa ulusi mu zamkati, kupititsa patsogolo kufanana kwa zamkati, ndikuwongolera pepala.

Kugwiritsa ntchito polyacrylamide muukadaulo wopanga mapepala

1. Gawo lokonzekera zamkati

Panthawi yokonzekera zamkati, ulusi wabwino ndi zodzaza zimatayika mosavuta ndi madzi oyipa, zomwe zimapangitsa kuwononga zinthu komanso kuwononga chilengedwe. Kugwiritsa ntchito cationic Polyacrylamide monga chothandizira posungira kumatha kugwira bwino ndi kukonza ulusi waung'ono ndi zodzaza mu zamkati kudzera mu kuletsa neutralization ndi kumangirira. Izi sizingochepetsa kutayika kwa ulusi, komanso zimachepetsa kutsitsa kwa zimbudzi.

2. Paper makina chonyowa mapeto dongosolo

M'makina a mapepala onyowa kumapeto, kutaya madzi m'thupi mwachangu ndiye chinsinsi chothandizira kupanga bwino. Anionic kapena nonionic polyacrylamide angagwiritsidwe ntchito ngati fyuluta thandizo kuti mosavuta madzi kuthawa dongosolo CHIKWANGWANI maukonde ndi kuwongolera flocculation pakati ulusi. Njirayi imafupikitsa kwambiri nthawi yotaya madzi m'thupi pomwe imachepetsa kugwiritsa ntchito mphamvu panthawi yowuma.

3. Kupanga mapepala

Monga dispersant, polyacrylamide amatha kuteteza CHIKWANGWANI flocculation ndi bwino yunifolomu ndi pamwamba kusalala kwa pepala. Posankha mosamala kulemera kwa mamolekyu ndi kachulukidwe ka PAM, mawonekedwe a pepala lomalizidwa, monga kulimba kwamphamvu ndi kung'ambika, amathanso kukongoletsedwa. Kuphatikiza apo, polyacrylamide imathanso kusintha mawonekedwe a pepala TACHIMATA ndikupanga kusindikiza kwa pepala bwino.

Ubwino waukulu wa Polyacrylamide pakuwongolera magwiridwe antchito

1. Chepetsani kuwonongeka kwa zinthu

Kugwiritsa ntchito zida zosungirako kumathandizira kwambiri kusungidwa kwa ulusi wabwino ndi zodzaza mu zamkati, kumachepetsa kugwiritsa ntchito zinthu zopangira, ndikupulumutsa mwachindunji mtengo wopangira.

2. Kufulumizitsa ndondomeko ya kutaya madzi m'thupi

Kuyambitsidwa kwa zida zosefera kumapangitsa kuti kuthira madzi kukhale kothandiza kwambiri, motero kumawonjezera liwiro la makina amapepala ndikufupikitsa nthawi yopangira. Izi sizimangowonjezera mphamvu zopanga zokhazokha, komanso zimachepetsa mphamvu zamagetsi.

3. Kuchepetsa kuthamanga kwa madzi otayira

Ndi kuwongolera zotsatira flocculation, Polyacrylamide angathe kuchepetsa zili zolimba inaimitsidwa mu madzi oipa, kuchepetsa Mumakonda zimbudzi mankhwala ku gwero ndi kuchepetsa mtengo chitetezo chilengedwe cha mabizinezi.

4. Konzani pepala labwino

Kugwiritsa ntchito ma dispersants kumapangitsa kugawa kwa pepala kukhala kofanana kwambiri, kumapangitsa kuti pepala likhale lowoneka bwino komanso lowoneka bwino, ndikukulitsa mpikisano wamsika wazinthuzo.

Zomwe zimakhudza ntchito ya polyacrylamide

Kuti mupereke sewero lathunthu pakuchita kwa Polyacrylamide, zotsatirazi ziyenera kuyang'ana pa:

1. PAM kusankha chitsanzo

Njira zosiyanasiyana zopangira mapepala ndi mitundu yamapepala zimakhala ndi zofunikira zosiyana pa kulemera kwa maselo ndi kachulukidwe ka PAM. Kulemera kwa ma molekyulu PAM ndikoyenera kuthamangitsidwa ndi zothandizira zosefera, pomwe molekyulu yotsika ya PAM ndiyoyenera kubalalitsidwa.

2. Kuonjezera kuchuluka ndi njira yowonjezera

Kuchuluka kwa PAM kowonjezera kuyenera kuyendetsedwa bwino. Kuchulukirachulukira kungayambitse zotsatira zoyipa, monga kusokoneza kuchepa kwa madzi m'thupi kapena kuonjezera mtengo wopangira. Panthawi imodzimodziyo, njira yowonjezeretsa yogawidwa mofanana iyenera kugwiritsidwa ntchito kuti tipewe kuphatikizira komwe kumakhudza zotsatira zake.

3. Mikhalidwe ya ndondomeko

Kutentha, pH ndi madzi zonse zimakhudza magwiridwe antchito a PAM. Mwachitsanzo, PAM ya cationic imagwira ntchito bwino mosalowerera ndale mpaka pang'ono acidic, pomwe PAM ya anionic ndiyoyenera malo amchere.

Monga chowonjezera chogwira ntchito zambiri pamakampani opanga mapepala, polyacrylamide imagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito, kuchepetsa mtengo wopangira komanso kuwongolera khalidwe lazogulitsa ndi flocculation yake yabwino, kusungidwa, kusefera ndi kubalalitsidwa. Muzochita zogwira ntchito, makampani amayenera kusankha moyenerera ndikuwongolera momwe angagwiritsire ntchito PAM potengera momwe amagwirira ntchito komanso zosowa zawo kuti akwaniritse zabwino zachuma ndi zachilengedwe.
