Muindasitiri yekugadzira mapepa, sodium carboxymethyl cellulose (CMC) inoshanda akati wandei akakosha mabasa mumatanho akasiyana ekugadzira mapepa.Heano maitiro eCMC muindasitiri yekugadzira mapepa:

1. Kuchengeta uye Kubatsira Kwemvura:
   • CMC inowanzoshandiswa sekuchengetedza uye rubatsiro rwemvura mukugadzira mapepa.Inonatsiridza kuchengetwa kwemafibers akanaka, mafirita, uye zvimwe zvinowedzera mumapepa epepa, zvichitungamira kusimba repamusoro repepa uye hunhu hwakatsetseka hwepamusoro.
   • CMC inokwidziridza kuyerera kwemvura kubva papepa pulp pawaya yekugadzira kana jira, zvichikonzera kukurumidza kudonha uye kuwedzera kugadzirwa kwakanaka.
   • Nekusimudzira kuchengetwa kwefiber uye kuzadza uye nekunatsiridza mvura, CMC inobatsira kuvandudza kuumbwa uye kufanana kwebepa, kuderedza hurema hwakadai sekutamba, mavara, uye maburi.
2. Kuvandudza Maumbirwo:
   • Sodium CMC inobatsira mukugadzirisa kuvandudzwa kwemapepa mapepa nekusimudzira kugovera uye kusungirirwa kwemafiber uye mafirita panguva yekugadzira pepa.
   • Inobatsira kugadzira yakawedzera yunifomu fiber network uye kugovera kwekuzadza, zvichikonzera kusimba kwepepa, kutsvedzerera, uye kudhinda.
   • CMC inoderedza maitiro emafiber uye mafirita kuungana kana kuungana pamwe chete, kuve nechokwadi chekugovanisa mukati mebepa rose uye kuderedza hurema hwakaita senge mottling uye isina kuenzana coating.
3. Kukura Kwepamusoro:
   • Mukuita saizi yekumusoro mashandisirwo, sodium CMC inoshandiswa seyepamusoro saizi mumiriri kuvandudza zvimiro zvebepa, senge kutsvedzerera, kugashira inki, uye mhando yekudhinda.
   • CMC inoumba firimu rakatetepa, rakafanana pamusoro pepepa, richipa kupera kwakatsetseka uye kupenya kunosimudzira kutaridzika uye kudhindwa kwebepa.
   • Inobatsira kuderedza kupinza kweinki mupepa substrate, zvichikonzera kupinza kudhinda mifananidzo, kunatsiridza kubereka kwemavara, uye kuderedzwa kweinki kushandiswa.
4. Simba Enhancer:
   • Sodium CMC inoita sesimba rinowedzera mukugadzira mapepa nekuvandudza kubatana uye kubatana pakati pemapepa fiber.
   • Inowedzera kusimba kwechisungo chemukati (kusimba kwesimba uye kubvarura kuramba) kwepepa repepa, zvichiita kuti rive rakasimba uye risingagadzirire kubvarura nekuputika.
   • CMC inokwidziridzawo kunyorova kwesimba rebepa, kudzivirira yakawandisa deformation uye kudonha kweiyo bepa chimiro kana yakafumurwa kune hunyoro kana mvura.
5. Controlled Flocculation:
   • CMC inogona kushandiswa kudzora flocculation yemapepa pulp fiber panguva yekugadzira mapepa.Nekugadzirisa dosage uye huremu hwemamorekuru eCMC, maitiro ekuyerera kwemafibhi anogona kuvandudzwa kuti avandudze mvura uye maitiro ekugadzira.
   • Kudzorwa kuyerera neCMC kunobatsira kuderedza fiber flocculation uye agglomeration, kuve nechokwadi chekupararira kweyunifomu yefiber uye mafirita mukati mepepa pulp kumiswa.

sodium carboxymethyl cellulose (CMC) inoita basa rakakosha muindasitiri yekugadzira mapepa nekushanda sekuchengetedza uye dhiraivha yekubatsira, kuumba inovandudza, pamusoro saizi mumiriri, simba rekusimudzira, uye inodzorwa flocculation mumiririri.Hurukuro hwayo, kugarisana, uye kushanda kwayo kunoita kuti ive yekuwedzera yakakosha mumagiredhi akasiyana-siyana emapepa, kusanganisira mapepa ekudhinda, mapepa ekurongedza, mapepa ematishu, uye mapepa ehunyanzvi, zvichibatsira mukuvandudza kunaka kwepepa, kuita, uye kukosha.
