Nā ʻano a me ka hoʻohana ʻana i nā kemika pepa

ʻO nā kemika pepa e pili ana i nā ʻano kemika i hoʻohana ʻia i ke kaʻina hana pepa, ka huaʻōlelo maʻamau o nā mea kōkua.Me ka laulā o nā ʻike:

nā kemika pulping (e like me nā mea kōkua kuke, nā mea hoʻohemo, etc.)

Nā kōkua kuke: hoʻohana ʻia e hoʻolōʻihi i ka wikiwiki a me ka hoʻoulu ʻana o ka kuke pulping kemika, hoʻohana maʻamau i ka anthraquinone a me ka quinone derivatives, surfactants a pēlā aku.

Deinking agent: Hoʻohana ʻia ia no ka deinking i ke kaʻina o ka hoʻomaʻamaʻa ʻana i ka pepa ʻōpala a me ka hoʻoulu hou ʻana, hiki ke hoʻomaikaʻi i ke keʻokeʻo o ka pulp a hoʻopau i nā mea haumia like ʻole e like me nā kiko inika, a me nā mea ʻē aʻe. detergent, a me ka anti-reprecipitant.

nā kemika pepa (e like me ka pulp sizing agents, surface size agent, etc.):

ʻO ka pulupulu ʻano ʻana: ka mea hoʻohui ʻia i ka pulp, i mea e pāʻani ai i ke ʻano o ka nui, maʻamau ka rosin saponification gum, reinforced rosin gum, dispersed rosin gum (anionic dispersed rosin gum, cationic dispersed rosin gum), AKD a me ASA a me nā mea ʻē aʻe. synthetic neutral sizing agent, petroleum resin sizing agent a pela aku.

Mea hoʻohana ʻili: hoʻohana ʻia no ka nui o ka pepa e hoʻomaikaʻi i ka ikaika o ka ʻili o ka pepa, hoʻemi i ka pauka, lint a me nā mea ʻē aʻe, ka starch i hoʻololi ʻia, e like me ka starch oxidized, starch acetate, crosslinked starch;cellulose i hoʻololi ʻia, e like me carboxymethyl cellulose;nā polymers synthetic, e like me ka polyvinyl alcohol, polyacrylates, styrene maleic anhydride copolymers, wax emulsions a pēlā aku;polymer maoli, e like me chitosan, gelatin a pēlā aku.

nā mea hana kemika pepa (e like me ka antifoam agent, coating auxiliary)

antifoam agent: hoʻohana ʻia i ka pulping, ka hana pepa, ka uhi ʻana a me nā kaʻina hana ʻē aʻe o ka defoaming, nā ʻano nui o ka lima lānahu a i ʻole emulsified kerosene, fatty acid esters, low carbon alcohols, silicones, amides a pēlā aku.

nā mea kōkua uhi: lubricants, e like me ka calcium stearate dispersion;nā mea mālama, e like me isothiazolinone, p-chloro-m-toluene;nā mea hoʻopuehu, e like me ka sodium hexametaphosphate, sodium polyacrylate;viscosity modifiers, e like me CMC, alkali soluble uplift o ka sodium polyacrylate a pela aku.

ʻO ke kumu o ka hoʻomaikaʻi ʻana i ka maikaʻi o ka pepa a me ka pono hana, hoʻomaikaʻi i nā kūlana hana, hoʻemi i nā kumukūʻai hana, hoʻonui i nā pono waiwai a hoʻomohala i nā ʻano pepa hou.
