Ụdị na Ngwa nke kemịkalụ akwụkwọ

Kemịkalụ akwụkwọ na-ezo aka n'ụdị kemịkalụ dị iche iche a na-eji na-eme akwụkwọ, okwu izugbe nke ndị inyeaka. Gụnyere ọtụtụ ọdịnaya:

kemịkalụ pulping (dị ka ihe enyemaka nri, ihe ndị na-emepụta ihe, wdg)

Enyemaka isi nri: eji eme ka ọsọ ọsọ na mkpụrụ nke nri kemịkalụ pulping nri, nke a na-ejikarị nwere anthraquinone na quinone derivatives, surfactants na ndị ọzọ.

Deinking agent: A na-eji ya maka deinking na usoro nke mkpofu akwụkwọ mweghachi na re-pulping, nke nwere ike imeziwanye ọcha nke pulp ma wepụ ihe dị iche iche adịghị ọcha dị ka ntụpọ ink, wdg. Ọ na-abụkarị nke surfactant, onye na-ejikọta ọnụ, onye na-acha ọcha, detergent, na mgbochi reprecipitant.

kemịkalụ akwụkwọ (dị ka ihe na-eme ka ihe na-eme ka pulp, onye na-ahụ maka nha elu, wdg):

Onye na-eme ihe na-edozi ahụ: onye na-emepụta ihe na-agbakwunye na pulp, iji rụọ ọrụ nke nha, n'ozuzu rosin saponification chịngọm, rosin chịngọm, rosin chịngọm (anionic chụgara rosin chịngọm, cationic chụgara rosin chịngọm), AKD na ASA na ndị ọzọ reactive sịntetik na-anọpụ iche sizing, petroleum resin on sizing agent.

Onye na-ahụ maka nha ihu elu: eji eme ka mpempe akwụkwọ dịkwuo elu iji meziwanye ike nke akwụkwọ, belata ntụ ntụ, lint na ihe ndị ọzọ, starch gbanwetụrụ, dị ka starch oxidized, starch acetate, starch crosslinked; cellulose gbanwere, dị ka carboxymethyl cellulose; polymer synthetic, dị ka mmanya polyvinyl, polyacrylates, styrene maleic anhydride copolymers, wax emulsions na ndị ọzọ; polymer eke, dị ka chitosan, gelatin na ndị ọzọ.

kemịkalụ nhazi akwụkwọ (dị ka onye na-ahụ maka ụfụfụ, ihe inyeaka mkpuchi)

onye na-ahụ maka antifoam: eji na pulping, papermaking, mkpuchi na usoro ndị ọzọ nke defoaming, isi iche nke coal aka uwe ma ọ bụ emulsified kerosene, fatty acid esters, obere carbon alcohols, silicones, amides na na.

ihe mkpuchi mkpuchi: mmanụ aṅụ, dị ka calcium stearate dispersion; ihe nchekwa, dị ka isothiazolinone, p-chloro-m-toluene; ihe na-agbasasị, dị ka sodium hexametaphosphate, sodium polyacrylate; viscosity modifiers, dị ka CMC, alkali soluble uplift nke sodium polyacrylate na na.

Ebumnuche bụ iji melite ogo akwụkwọ na mmepụta mmepụta ihe, melite ọnọdụ ọrụ, belata ụgwọ ọrụ mmepụta ihe, ịbawanye uru akụ na ụba na ịmepụta ụdị akwụkwọ ọhụrụ.
