Kaʻina hana polyacrylamideʻo ia hoʻi ka batching, polymerization, granulation, hoʻomaloʻo, hoʻoluʻu, ʻokiʻoki a me ka hoʻopili.Hoʻokomo ka mea maka i loko o ka ipuhao dosing ma o ka pipeline, hoʻohui i nā mea hoʻohui like e hui like, hoʻoluʻu i 0-5 ℃, hoʻouna ʻia ka mea maka i ka ipu polymerization ma o ka nitrogen deoxygenation, hoʻemi ʻia ka ʻike o ka oxygen i kahi 1%, hoʻohui i ka ka mea hoʻomaka no ka polymerization, ma hope o ka polymerization, ʻokiʻoki ʻia ka pahu pahu, hoʻouna ʻia i ka pelletizer no ka granulation, nā pellets granulated i hoʻouna ʻia i ka moena maloʻo no ka maloʻo.Hoʻounaʻia ka mea maloʻo i ka'ōnaehana'ōpala a me ka nānāʻana no ka'ōpala.Ma hope o ka ʻoki ʻana, komo ka mea i loko o ka ʻōnaehana pale no ka hoʻopili ʻana a hana i ka huahana i hoʻopau ʻia.
Polyacrylamideʻelua ʻanuʻu ke kaʻina hana
ʻenehana hana monomer
Hoʻokumu ʻia ka hana ʻana o ka monomer acrylamide ma ka acrylonitrile ma ke ʻano he maka, ma lalo o ka hana o ka catalyst hydration e hana i ka huahana crude o ka acrylamide monomer, ma hope o ka flash distillation, hoʻomaʻemaʻe acrylamide monomer, ʻo kēia monomer ka mea maka no ka hana ʻana o ka poly444 acrylamide.
Acrylonitrile + (hoʻoheheʻe wai/wai) → hui ʻia → acrylamide maʻemaʻe → uila → hoʻomaʻemaʻe → acrylamide hoʻomaʻemaʻe.
Hoʻohana ʻia ka wai wai polyacrylamide ma ke ʻano he mea maka no ka hana ʻana.Ma lalo o ka hana a ka mea hoʻomaka, lawe ʻia ka hopena polymerization.Ma hope o ka pau ʻana o ka hopena, ʻoki ʻia ka poloka polyacrylamide gum i hana ʻia, granulated, maloʻo a ʻokiʻoki ʻia, a ma hope ua mākaukau ka huahana polyacrylamide.ʻO ke kaʻina hana nui he polymerization.Ma ke kaʻina hana lapaʻau e pili ana, pono e uku ʻia i ka hoʻoluʻu mechanical, degradation thermal a me ka crosslinking, i mea e hōʻoia ai i ka paona molekala pili a me ka solubility wai o polyacrylamide.
Acrylamide+ wai (mea hoʻomaka/polymerization) → polyacrylamide gum block → granulation → hoʻomaloʻo → ʻohi → polyacrylamide huahana
