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:

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

1. Nā kōkua kuke: hoʻohana ʻia e hoʻolōʻihi i ka wikiwiki a me ka hoʻohua ʻana o ka kuke ʻana i ka pulping kemika, hoʻohana maʻamau i ka anthraquinone a me ka quinone derivatives, surfactants a pēlā aku.
2. Deinking agent: Hoʻohana ʻia ia no ka deinking i ke kaʻina hana o ka hoʻoheheʻe ʻana i ka pepa ʻōpala a me ka pulping hou, hiki ke hoʻomaikaʻi i ka keʻokeʻo o ka pulp a hoʻopau i nā mea haumia like ʻole e like me nā kiko inika, a me nā mea ʻē aʻe.

pepa kemika (e like mepulpnā mea hoʻohana nui,mea hoʻonui ʻili, etc.):

1. Mea hoʻonui ʻana i ka pulp: hoʻohui ʻia ka mea nui i ka pulp, i mea e pāʻani ai i ke ʻano o ka hoʻonui ʻana, ma ke ʻano maʻamau ʻo 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 reactive synthetic neutral sizing agent, petroleum resin sizing agent a pēlā aku.
2. Mea hoʻonui i ka ʻili: hoʻohana ʻia no ka hoʻonui ʻana i ka ikaika o ka pepa, e 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 memea hoʻopalekana, ka uhi ʻanamau kokua)

1. antifoam agent: hoʻohanaʻia i ka pulping, ka pepa pepa, ka uhiʻana a me nā kaʻina hana'ē aʻe o ka defoaming, nāʻano nui o ka lima lānahu a iʻole ka emulsified kerosene, nā momona momona esters, nā haʻahaʻa carbon carbon, silicones, amides a pēlā aku.
2. uhi auxiliaries: 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 maikaʻi o ka hana, hoʻomaikaʻi i nā kūlana hana, hoʻemi i nā kumukūʻai hana, hoʻonui i nā pono waiwai a hoʻomohala i nā ʻano pepa hou.
