Zizindikiro zitatu zomwe muyenera kutchera khutu posankha Pam

Polyacrylamide. Zizindikiro za Pam Phatikizani Ionicity, hydroly digiri ya ma hydrolys, zolemera maselo, etc. Zisonyezo izi zimakhudza kwambiri pakugulitsa madzi. Kuzindikira zisonyezo izi kumakuthandizani kusankha mwachangu Pam ndi zigawo zoyenera.

Kungosoka

Loonality amatanthauza ngati Pam ma molecular unyolo umakhala ndi zolipiritsa zabwino kapena zoyipa. Kuchuluka kwa mankhwalawa kumakhudza kwambiri poyendetsa madzi. Nthawi zambiri, ionicity wapamwamba, wabwinobwino. Izi ndichifukwa choti maunyolo a ionic kwambiri amatenga ndalama zambiri ndipo amatha kuyamwa bwino tinthu tating'onoting'ono, ndikupangitsa kuti asonkhanitse pamodzi kuti apange zingwe zazikulu.

Polyacrylamide amagawika mu Anionic (Akham), CPAM), komanso zopanda tanthauzo (NPAM) kutengera ionicty yawo. Mitundu itatu iyi ya Pam ili ndi zovuta zosiyanasiyana. Pamapulogalamu othandiza, oinocity oyenera ayenera kusankhidwa malinga ndi mtengo wamtengo wamwazi zomwe zimaperekedwa, electronegatata, ndi ndende zoyimitsidwa. Mwachitsanzo, kwa madzi acidic acidic, omwe ali ndi mawonekedwe okwera ayenera kusankhidwa; Kwa madzi amchere a alkaline, pamtunda ndi anionicity apamwamba ayenera kusankhidwa. Kuphatikiza apo, kukwaniritsa zotsatira zabwino zanyumba, zitha kupezekanso mwa kusakaniza Pam ndi madigiri osiyanasiyana a ionic.

Digiri ya hydrolysis (ya AkhAM)

Mulingo wa hydrolysis wa Pam amatanthauza kuchuluka kwa hydrolysis a madera amtundu wa majekeni ake. Mulingo wa hydrolysis amatha kugawidwa mu otsika, sing'anga, komanso madigiriitali a hydrolysis. Pam ndi madigirii osiyanasiyana a hydrolysis ali ndi zinthu zosiyana ndikugwiritsa ntchito.

Pam ndi digiri yotsika ya hydrolysis imagwiritsidwa ntchito poti amakula ndi kukhazikika. Zimawonjezera mawidwe a yankho, lololeni tinthu tayimitsidwa kuti zitheke bwino. Amagwiritsidwa ntchito kwambiri pakubowola zamadzimadzi, zokumba, ndi malonda.

Pam ndi digiri ya hydrolysis imakhala ndi mphamvu yabwino komanso yoyenera chithandizo chamadzi chosiyanasiyana. Itha kugawanika ma tinthu tating'onoting'ono kuti apange zingwe zazikulu kudzera mwa adsorption ndi kung'ung'udza, potero pezani kukhazikika mwachangu. Amagwiritsidwa ntchito kwambiri m'minda ya chithandizo cha utatu, chithandizo chamadzi madzi, ndi snudge madzi.

Pam ndi digiri yapamwamba ya hydrolysis ali ndi mphamvu zolimba komanso kuthekera kosinthika ndipo nthawi zambiri imagwiritsidwa ntchito posindikiza ndi kupatsa mankhwala othandizira madzi ndi minda ina. Imatha kudsorb ndi kuchotsa zinthu zoyipa mu madzi onyansa, monga utoto, zitsulo zolemera, ndi zinthu zachilengedwe, kudzera munjira ndi ma adsorption pa unyolo wa polymer.

Kulemera kwa maselo

Kulemera kwa Pam kumatanthawuza kutalika kwa mawonekedwe ake. Nthawi zambiri, kulemera kwamwambo, kulibwino kwabwino. Izi ndichifukwa choti kuchuluka kwa zolemera kwambiri pamtunda kumatha kukhala bwino adsorb kuyimitsidwa, kuwapangitsa kuti azisonkhana pamodzi kuti apange zingwe zazikulu. Nthawi yomweyo, kuchepa kwa thupi kwambiri kwa olemera kumakhala bwino komanso kukhazikika kwamphamvu, komwe kumatha kusintha mphamvu ndi kukhazikika kwa gulu.

Pogwiritsa ntchito, kulemera kwa ma Pam yomwe imagwiritsidwa ntchito kwa mankhwala am'mizinda ndi mafakitale afakitale kumafuna zofunikira zapamwamba, kuyambira mamiliyoni mamiliyoni ambiri. Zomwe zimagwiritsidwa ntchito molecular zomwe zimagwiritsidwa ntchito pakugwiritsa ntchito mankhwala a sludge kudziphako zimakhala zochepa, nthawi zambiri kuyambira mamiliyoni ambiri mpaka mamiliyoni ambiri.

Pomaliza, zisonyezo monga ma ionicity, degree digiri ya hydroly, ndi zolemera molecula ndi zinthu zofunika kwambiri zomwe zimakhudza ntchito yomwe imagwiritsa ntchito madzi m'madzi. Mukamasankha Pams, muyenera kuganizira bwino za madzi ndikusankha molingana ndi zisonyezo zaluso kuti mupewe kukwera bwino, kukonza bwino ntchito, komanso chithandizo chamadzi.
