Henan Saike Environmental Protection y'ekola polyacrylamide mu Gongyi. Mu myaka egiyise, amakolero g'empapula ag'omu ggwanga gakola enkulaakulana ey'amangu, nga gakola mu kifo eky'okusatu mu nsi yonna era nga gakulaakulana buli mwaka. Waliwo obutali bwenkanya bw'ebikoola by'emiti, naddala abazimbi b'ebikoola ebinene, mu ggwanga lyaffe. Empapula nnyingi zeetaaga okuteekebwawo n'empapula z'emiti ez'amabala amangi, empapula z'amabala, n'empapula ezikozesebwa, ekijja kuleetawo amaanyi g'empapula okukendeeza. N'olwekyo, enteekateeka zeetaaga okutwalibwa okulongoosa amaanyi g'empapula.

Amaanyi g'empapula gafugibwa amaanyi g'enkolagana wakati w'ebikoola. Okukozesa ebikozesebwa mu kuyamba empapula ngeri nnungi ey'okunyweza enkolagana wakati w'ebikoola, ekiyinza okwewala okwongera kw'okunyweza empapula, okukyuka kw'ebbugumu, obutaba na bubonero, okunywa, okufumba, n'okuziyiza okunywa okuva ku kweyongera kw'omutindo gw'okulumba. Tukola "Cationic Polyacrylamide for Paper Industry", era mu kiseera kino ekikozesebwa okunyweza empapula kye cationic polyacrylamide. Cationic polyacrylamide ya bbeeyi entono era erina enkola ey'amaanyi ey'okunyweza ku mpapula, awamu n'enkola ey'amaanyi ey'okukuuma ku bintu ebijjuza n'ebitundu ebirabika obulungi. Ekitundu kya pH ekya cationic polyacrylamide eky'okukola empapula kisobola okutuuka ku bivaamu ebirungi okuva ku acidic okutuuka ku neutral. Okwongera polyacrylamide ey'ekika kya cationic ng'ekikozesa amaanyi ag'ekikalu mu pulp kiyinza okulongoosa amaanyi g'okukwatagana wakati w'ebikoola, ne kifuula empapula okuba n'amaanyi ag'okuziyiza, okuziyiza, n'amaanyi g'empapula. Ng'ekikozesebwa mu kutwala amaanyi, kirina ebikolwa ebirungi, omutindo ogutono, era n'ebbeeyi entono. Okwongera omuwendo ogutono kuyinza okutuuka ku maanyi amalungi ag'okukyusa n'ag'okukyusa.

Polyacrylamide, ng'ekikozesebwa mu kukola empapula mu makolero g'empapula, si kyokka kye kirina ekifo mu kukuuma n'okufuula okulongoosa amaanyi g'empapula, naye era n'ekendeeza ku bbeeyi n'okwongera ku miganyulo gy'ebyenfuna. Ng'omukola polyacrylamide alina emyaka mingi egy'obumanyirivu mu kukola, SECCO Environmental Protection esangirira ebibuuzo okuva eri bakasitoma.
