Noocyada iyo Codsiga kiimikada waraaqaha

Kiimikooyinka warqaddu waxay tilmaamayaan kiimikooyin kala duwan oo loo isticmaalo habka samaynta waraaqaha, ereyga guud ee kaaliyayaasha. Oo ay ku jiraan waxyaabo badan oo kala duwan:

kiimikooyinka garaaca (sida qalabka wax lagu kariyo, walxaha deinking, iwm.)

Aaladaha wax lagu kariyo: waxaa loo isticmaalaa in lagu dardar geliyo xawaaraha iyo wax-soosaarka karinta kiimikaad, sida caadiga ah loo isticmaalo guud ahaan waxay leeyihiin anthraquinone iyo quinone derivatives, surfactants iyo wixii la mid ah.

Wakiilka Deinking: Waxaa loo isticmaalaa deinking habka dib u warshadaynta waraaqaha qashinka iyo dib-u-saarista, taas oo hagaajin karta cadaanka saxarka iyo baabi'inta wasakhaha kala duwan sida dhibco khad, iwm. Waxa ay inta badan ka kooban tahay surfactant, integrating agent, bleaching agent, saabuun, iyo anti-reprecipitant.

kiimikooyinka waraaqaha ah (sida wakiilada cabbirka saxarka, wakiilka cabbirka dusha, iwm.):

Wakiilka cabbiraadda saxarka: wakiilka cabbirka ee lagu daray saxarka, si uu u ciyaaro doorka cabbirka, guud ahaan rosin saponification xanjo, xanjo rosin ah oo la xoojiyay, rosin xanjo la firdhiyey (xanjo rosin ah oo kala firdhisay, xanjo cationic la firdhiyey), AKD iyo ASA iyo wakiilka cabbiraadda dhexdhexaadka ah ee synthetic dhexdhexaad ah, saabuunta batroolka ee saabuunta.

Wakiilka cabbiraadda dusha sare: waxaa loo isticmaalaa cabbirka dusha warqadda si loo hagaajiyo awoodda dusha sare ee warqadda, la dhimo budada, lint iyo ifafaale kale, inta badan istaarijka wax laga beddelay, sida istaarijka oksaydhka ah, istaarijka acetate, istaarijka istaroogga ah; cellulose wax laga beddelay, sida cellulose carboxymethyl; polymers synthetic, sida khamriga polyvinyl, polyacrylates, styrene maleic anhydride copolymers, emulsions wax iyo wixii la mid ah; polymer dabiiciga ah, sida chitosan, jelatin iyo wixii la mid ah.

kiimikooyinka farsamaynta waraaqaha (sida wakiilka antifoam, kaabayaal daahan)

wakiilka antifoam: loo isticmaalo in pulping, waraaqaha, daahan iyo hababka kale ee defoaming, noocyada ugu muhiimsan ee gacan dhuxusha ama kerosene emulsified, esters acid dufanka leh, alkolada hoose ee carbon, silicones, amides iyo wixii la mid ah.

kaaliyayaasha daahan: saliidaha, sida kala firdhiso stearate calcium; waxyaalaha ilaaliya, sida isothiazolinone, p-chloro-m-toluene; walxaha kala firdhiya, sida sodium hexametaphosphate, sodium polyacrylate; wax ka beddelayaasha viscosity, sida CMC, alkali soluble uplift of sodium polyacrylate iyo wixii la mid ah.

Ujeedada ayaa ah in la wanaajiyo tayada waraaqaha iyo waxtarka wax soo saarka, hagaajinta xaaladaha shaqada, dhimista kharashaadka wax soo saarka, kordhinta faa'iidooyinka dhaqaale iyo horumarinta noocyada waraaqaha cusub.
