ʻO ka polyacrylamide kahi polymer linear, ua māhele nui ʻia ka huahana i ka pauka maloʻo a me nā ʻano colloidal ʻelua. E like me kona awelika molecular kaumaha, hiki ke maheleia i haʻahaʻa molecular kaumaha (<1 miliona), medium molecular kaumaha (2 ~ 4 miliona) a me kiʻekiʻe molecular kaumaha (>.7 miliona). E like me kona hale hiki ke maheleia i non - ionic, anion a me ka cationic. Hoʻoheheʻe wai (HPAM) o ke ʻano anion. ʻO ke kaulahao nui o ka polyacrylamide ka nui o nā pūʻulu amide, me ka hana kemika kiʻekiʻe, a hiki ke hoʻololi ʻia e hana i nā derivatives o polyacrylamide. Ua hoʻohana nui ʻia nā huahana i ka hana pepa, ka hoʻoili ʻana i ka mineral, ka ʻili ʻaila, ka metallurgy, nā mea kūkulu hale, ka mālama ʻana i ka wai a me nā ʻoihana ʻē aʻe. Ma ke ʻano he lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducing agent a me thickening agent, polyacrylamide ua hoʻohana nui ʻia i ka wili, acidification, fracturing, water plugging, cementing, secondary oil recovery and tertiary oil recovery.

1. ka paʻi ʻana a me ka hoʻoluli ʻana i ka wai ʻino

ʻO ka paʻi ʻana a me ke kala ʻana i ka wai ʻino, ma kahi o nā coagulants haʻahaʻa haʻahaʻa haʻahaʻa, pili i ke ʻano nui o ka coagulant, ʻoi aku ka maikaʻi o ka coagulation, ʻoi aku ka maikaʻi o nā kūlana ph penei: 8.0.

2.Papermaking hoʻomaʻemaʻe wai

ʻO ka hoʻomaʻamaʻa ʻana i ka wai ʻōpala pepa, ka mea i hoʻohana ʻia e like me ka coagulant ma kahi o ka polyaluminum chloride, alumini sulfate, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia e like me ka hoʻoheheʻe ʻana o ka sludge papermaking.
