Nā hōʻikeʻenehana oPoyucrylamke kaupaona nuiʻana, hydtrolysis degere,ʻo ka pae kula, he chancoisity, cenctiesity
01Kaupaona molebular
ʻO ke poʻo kino maʻamau o Pam, he kiʻekiʻe loa aʻo ka maikaʻi loa i hoʻomaikaʻiʻia i nā makahiki i hala.Pam, i hoʻohanaʻia ma ka makahiki 1970, he mau kaumaha molela o nā miliona miliona. Mai ka makahiki 1980, ke kaupaona nui o nā'āpana nui o ka pam o ka nui o ka nui o 15 miliona, a hiki i 20 miliona. "ʻO kēlā me kēia o kēia mau molenaʻo Polecules i polelaʻia mai kahiʻoi aku ma mua o hoʻokahi haneli tausani a iʻole he mau makahiki he nui o nā molena
Ma ka laulā,ʻo Pam me kahi kaumaha molele kiʻekiʻe e loaʻa ai kahi momona kiʻekiʻe, me kahi paona mollemulari no 71 miliona no ka Pamond a me ka nui. ʻO ka mollecular o Polyular o Polyacrylamide a me kāna mau derivatives mai nā haneli he 10 miliona mau molena (10 miliona mau moleka
ʻO ke kaumaha molecular o ka mea pilikino macromolecular,ʻaʻole ia ma ka huahana likeʻole,ʻaʻole piha i ka lole
02Tree of hydrolysis a me ke kiʻekiʻe o ka Ion
He hopena o ka Iniko o Pam i kahi hopena nui ma kona hoʻohanaʻana, akā aia konaʻano kūpono i hanaʻia ma keʻano o nāʻano mea likeʻole. Ināʻoi aku ka nui o ka ikaika o keʻano o ka waiwai i hanaʻia (loaʻa i nā mea hana hou aʻe) Ma ka laulā, ua kapaʻia ke kiʻekiʻe o ke anioni i ke kiʻekiʻe o ka hydrolysis. A me ka papa kuhikuhi oniic maʻamau e pili ana i nā ciations.
Ionicility = n / (m + n) * 100%
ʻO ka pam i hanaʻia ma keʻano mua ua pololiʻia mai kahi Monomer Ma mua o ka hoʻohanaʻana, pono e hoʻohuiʻiaʻo Naoh i ka Hydrolyze kahi'āpana o ka -conh2 Group i -coona. ʻO ka hoʻohālikelike penei:
-Nconi2 + naoh → -coona + NH3 ↑
Hoʻokuʻuʻiaʻo Amonnia i ka wā o ka hydrolysis. ʻO ka hapa nui o ka huiʻana o ka huiʻana o ka huiʻana i ka pam i kapaʻia ke kiʻekiʻe o ka hydrolysis o Pam,ʻo ia ka nui o keʻano. ʻAʻole kūpono ka hoʻohanaʻana o kēiaʻano o ka pam, a heʻilihune ka hana
Heʻano hana likeʻole o ka pam i nā huahana heion likeʻole, hiki i ka mea hoʻohana ke koho i kaʻano kūpono,ʻaʻole pono e hoʻohanaʻia.Eia nō naʻe, no nā kumu kumu, e pili ana kekahi poʻe i ke kaʻina hana o nā flocculants e like me ka hydrolysis. Pono e hoʻomaopopoʻiaʻo ia keʻano o ka hydrolossis ka decomposition o ka wai,ʻo ia kahi hopena o keʻano. ʻO ka Hyddolysus o Photo,ʻaʻohe keiki ambeia angalola. ʻO ka weheʻana he hana pilikino wale nō,ʻaʻohe hopena o ka cmocal. ʻOkoʻa nā mea maʻamauʻelua aʻaʻole pono e hilahila.
03ʻO nāʻike Monomer
ʻO kaʻikepili Monomer Sandual o Pam e pili ana i nā mea e pili ana i kaʻike oacrylamide monomerI ka Polokalamu Polokalamu Acrylamide i loko o ka poliacrylamide ma ke kaʻina o ka hopena o ka hopenaʻole a me ke koena ma hope o nā huahana acrylade. Heʻano koʻikoʻi ia e hoʻopaʻa ai inā kūpono ia no kaʻoihana meaʻai. ʻO Poyacrylallamʻaʻole he lapuwale, akā ua loaʻa i kekahi mea i kekahi mea i loko o ka mea aloha. I loko o ka pāʻoihanaʻoihana No laila,ʻo kaʻike o ke ola noho noho maNā huahana pampono e kāohi paʻa. ʻAʻoleʻaeʻia ka nui o ka monimer i loko o ka pam i hoʻohanaʻia ma ka inu wai inu a me kaʻoihana meaʻai i hāʻawiʻia i ka 0,05%. ʻO ka waiwai o nā huahana haole kaulana he haʻahaʻa ma mua o 0,03%.
04Viscosity
ʻO ka snow gree stemor he viscous. Ke kiʻekiʻe kiʻekiʻe o ke kaumaha o ka pam,ʻo ia ka meaʻoi aku ka viscosity o ka hopena. ʻO kēia no ka mea he lōʻihi nā macromolecules, nā kaulahao i nā kaulahao nui e loaʻa ke kū'ēʻana i ka neʻeʻana o ka hopena. ʻO keʻano o ka viscosity e hōʻike i ka nui o ka ikaika o ka ikaika o ka ikaika i loko o ka hopena,ʻikeʻiaʻo keʻano o keʻano kūloko. ʻO ka Viscosity o ka hopena o nāʻano o nāʻano likeʻole o nāʻano polymer seganic he kiʻekiʻe a kiʻekiʻe a hoʻonui i ka piʻiʻana o ke kaumaha mole. He ala e hoʻoholo ai i ke kaumaha o ka molecular o nā mea hana polymer o ka mea i loaʻa i kahiʻano o kekahi mau kūlana
