No ke ahaDispersant NNOhana?
Dispersant NNOLoaʻa i nā molekala nā pūʻulu heleuma a me nā ʻāpana hoʻopaʻa. ʻO ke kuleana o ka hui heleuma ʻo ia ka hāʻawi ʻana i kahi ikaika hoʻopaʻa paʻa i nā ʻāpana pigment filler. ʻAʻole hāʻule nā molekala dispersant mai ka ʻili o nā ʻāpana, kahi mea e pono ai ka dispersant e hana. ʻO ka hana o ka ʻāpana stabilizing ka hoʻopaʻa ʻana i nā ʻāpana pigment aggregate i hoʻopuehu ʻia e ka mechanical force ma o ka electrostatic repulsion a me spatial resistance i loko o ka wai wai e pale ai i nā ʻāpana mai ka hui ʻana.
I nā mea hoʻoheheʻe organik, i ka wā i paʻa ai ka ʻāpana o kaDispersant NNOhoʻopaʻa i nā ʻāpana puaʻa i hoʻopuehu ʻia e ke kūʻē spatial, ke ʻoi aku ka liʻiliʻi o ka spacing o nā ʻāpana dispersant ma mua o ka nui o ke kaulahao solvent, ʻo ke kaulahao solvent squeezes kekahi i kekahi a emi ka entropy. I loko o ka wai, hana ʻia ka ionization a puni nā pūʻulu ionic e hana i kahi papa pālua, a pale ka electrostatic repulsion i ka hoʻohui ʻana o nā ʻāpana. Inā paʻa ka polyether non-ionized, hoʻopaʻa ka polyether i nā ʻāpana puaʻa i hoʻopuehu ʻia e ka pale ʻana i ka spatial.
I ke kaʻina hana o ka pulp a me ka hana pepa, pono ka nui o nā dispersants kemika pepa e hoʻoponopono i nā pilikia o ka hoʻopuehu, paʻa, kānana a pēlā aku. ʻO ka hoʻohui ʻana i nā mea hoʻopuehu kemika i ka pulp hiki ke hōʻemi i ka wili ʻana i ka fiber a hoʻomaʻamaʻa i ka pepa a me ka hana maikaʻi. ʻO ka mea maʻamau, hoʻohana ʻia nā mea hoʻohui kemika i ka pulp filtration, e like me ke kahe AIDS, nā kānana, nā dispersants, nā mea hoʻoikaika ikaika, nā mea hoʻoulu ʻana, nā preservatives, biological enzymes, a me nā mea ʻē aʻe. e hoʻomaikaʻi i ka maikaʻi o ka ʻaoʻao, hoʻomaikaʻi maikaʻi i ka hana hana, hoʻemi i ke kumu kūʻai.
ʻO ka fiber ke kumu nui e pili ana i ka maikaʻi o ka pepa ma ke kaʻina hana pepa. E like me kekahi lōʻihi fiber mea ilihune compatibility, hana additives, fillers a pela aku mai kekahi i kekahi, a laila, paʻakikī ke loaʻa i ka hana like, ka ikaika kūpono o ka pepa. Eia nō naʻe, me ka hoʻohui ʻana o ka dispersant kūpono, hiki i ka ʻili o nā ʻāpana paʻa ke hana i kahi hoʻolālā bimolecular, a hiki ke hoʻomaikaʻi ʻia ke kiʻekiʻe o ka mākū o nā ʻāpana paʻa. Pono kekahi mau dispersant fiber maikaʻi i kekahi mau waiwai pyrolytic, hiki ke hoʻomaikaʻi i ka dispersion pono me ka piʻi ʻana o ka mahana. A laila e ho'ēmi i ka viscosity o ka pulp, e hoʻomaikaʻi i ka ʻili o ka pepa a me ka palupalu.
