Kushandiswa kweCellulose Ethers muIndasitiri Yemapepa

Cellulose ethers inoita mabasa akakosha muindasitiri yemapepa, ichibatsira mukugadzirwa kweakasiyana siyana emapepa uye mapepa emapepa. Heano mamwe akajairika mashandisiro e cellulose ethers mune ino chikamu:

1. Kukura Kwepamusoro: Cellulose ethers anoshandiswa seanoshanda saizi yepasi mukugadzira mapepa kuvandudza mamiriro epamusoro epepa uye kuwedzera kudhinda, kutsvedzereka, uye inki adhesion. Vanoumba jira rakatetepa, rakafanana pamusoro pemapepa, kuderedza porosity yepasi, kudzivirira ink feathering, uye kunatsiridza ruvara rwemavara.
2. Kukura Kwemukati: Cellulose ethers inoshanda seyemukati saizi maajenti mukugadzira mapepa kusimudzira kuramba kwemvura uye kugadzikana kwedimensional yezvigadzirwa zvemapepa. Ivo vanopinda mumapepa fiber panguva yekunyorova-yekupedzisira maitiro, vachigadzira hydrophobic barriers iyo inoderedza kunyura kwemvura uye inowedzera kuramba hunyoro, hunyoro, uye kupinza kwemvura.
3. Kuchengeta uye Kubatsira Kwemvura: Cellulose ethers inoshanda sekuchengetedza uye dhiraivha inobatsira mukugadzira mapepa kuvandudza kuchengetwa kwe pulp, fiber flocculation, uye kudhiza kwemvura pamushini wemapepa. Ivo vanosimudzira kuumbwa uye kufanana kwemapepa mapepa, kuderedza faindi uye kurasikirwa kwemafirita, uye kuwedzera muchina kumhanya uye kugadzira.
4. Kuumba uye Kuvandudza Simba: Cellulose ethers inobatsira pakuumbwa uye kusimba kwezvigadzirwa zvemapepa nekuvandudza fiber bonding, interfiber bonding, uye kubatanidza mapepa. Ivo vanosimudzira kubatana kwemukati uye kusimba kwesimba remapepa, kuderedza kubvaruka, kuputika, uye kusungirira panguva yekubata nekushandura maitiro.
5. Kupfekedza uye Kusunga: Cellulose ethers inoshandiswa semabhainda uye zvekuisa zvinowedzerwa mumapepa uye kurapwa kwepamusoro kuvandudza kunamatira, kuvhara, uye kupenya. Vanonatsiridza kusungirirwa kwe pigment, mafirita, uye ekuwedzera kumapepa, achipa kutsvedzerera, kupenya, uye kudhinda mhando.
6. Functional Additives: Cellulose ethers inoshanda sezvinowedzera zvinoshanda mumapepa akasarudzika uye zvigadzirwa zvemapepa kuti zvipe zvakati zvinhu zvakaita sesimba rekunyorova, kuoma kwesimba, kuramba kwegirisi, uye zvipingamupinyi. Ivo vanosimudzira kuita uye kusimba kwezvigadzirwa zvemapepa mumashandisirwo akasiyana senge kurongedza, mavara, mafirita, uye mapepa ekurapa.
7. Rubatsiro rwekudzokorodza: ​​Cellulose ethers inofambisa kudzokororwa kwebepa uye zvigadzirwa zvemapepa nekuvandudza fiber dispersion, pulp suspension, uye inki detachment panguva yekudzoreredza uye deinking maitiro. Ivo vanobatsira kuderedza kurasikirwa kwefiber, kunatsiridza goho repulp, uye kuwedzera mhando yezvigadzirwa zvemapepa zvakadzokororwa.

cellulose ethers vanoita basa rakakosha muindasitiri yemapepa nekusimudzira kunaka, kuita, uye kusimba kwezvigadzirwa zvemapepa nemapepa. Kuita kwavo kwakasiyana-siyana, kuenderana, uye hunhu hune hushamwari hunovaita zvakakosha zvekuwedzera zvekugadzirisa mapepa ekugadzira mapepa uye kusangana nezvinoda kubuda zvemusika wemapepa.
