Mhedzisiro yeSodium Carboxymethyl Cellulose mune Wet End paPepa Hunhu

Sodium Carboxymethyl Cellulose (CMC) inowanzo shandiswa mukugadzira mapepa, kunyanya mukupera kwemvura, uko inotamba mabasa akati wandei akakosha anogona kukanganisa zvakanyanya kunaka kwepepa. Heano maitiro eCMC anobata zvakasiyana-siyana zvekugadzira mapepa:

1. Kuchengetedza uye Kuvandudza Drainage:
   • CMC inoita seyamuro yekuchengetedza uye yekubatsira kwemvura mukupera kwakanyorova kwemaitiro ekugadzira mapepa. Iyo inovandudza kuchengetwa kweakanaka zvimedu, mafirita, uye ekuwedzera mune pulp slurry, zvichitungamira kune nani kuumbwa uye kufanana kwepepa bepa. Pamusoro pezvo, CMC inokwidziridza dhiraivha nekuwedzera mwero wekubviswa kwemvura kubva pakumiswa kwepulp, zvichikonzera kukurumidza kudonhedza mvura uye nekunatsiridza mashandiro emuchina.
2. Kuumbwa uye Kufanana:
   • Nekuvandudza kuchengetedza uye dhiraivha, CMC inobatsira kusimudzira kuumbwa uye kufanana kwepepa bepa. Iyo inoderedza misiyano muhuremu hwehwaro, ukobvu, uye kutsvedzerera kwepasi, zvichikonzera kuenderana uye kwepamusoro-mhando yemapepa chigadzirwa. CMC inobatsirawo kuderedza kuremara senge mavara, maburi, uye mitsetse mupepa rakapera.
3. Kuwedzera Simba:
   • CMC inobatsira kune simba zvivakwa zvebepa nekuvandudza fiber bonding uye inter-fiber bonding. Inoita sefiber-fiber bond inosimudzira, inowedzera kusimba kwesimba, kubvarura simba, uye kuputika kwesimba rebepa. Izvi zvinoita kuti pave nechigadzirwa chebepa chakasimba uye chakasimba uye chinoramba chiri nani kubvaruka, kuboora, nekupeta.
4. Kudzora Kwekugadzira uye Kukura:
   • CMC inogona kushandiswa kudzora kuumbwa uye saizi yebepa, kunyanya mumhando yemapepa mamakisi. Inobatsira kudzora kugoverwa kwemafibhi uye mafirita mubepa pepa, pamwe nekupinda uye kuchengetwa kwemaajenti ekuyera senge starch kana rosin. Izvi zvinogonesa kudhinda kwakanyanya, kunyura kweinki, uye zvimiro zvepasi mubepa rakapera.
5. Surface Properties uye Coatability:
   • CMC inobatsira kune yepamusoro zvimiro zvebepa, zvinofurira zvinhu zvakaita sekutsvedzerera, porosity, uye kudhinda mhando. Inowedzera kufanana kwepamusoro uye kutsetseka kwepepa repepa, inovandudza kugadzikana kwayo uye kudhindwa. CMC inogona zvakare kuita sebhainda mukugadzirisa maumbirwo, zvichibatsira kunamatira pigment uye zvinowedzera kune bepa pamusoro.
6. Kudzora kweStickies uye Pitch:
   • CMC inogona kubatsira kudzora zvinamira (zvinonamira zvinosvibisa) uye namo (resinous zvinhu) mukugadzira mapepa. Iyo ine mhedzisiro yekuparadzira pane stickies uye pitch particles, kudzivirira iwo agglomeration uye kuisa panzvimbo yemapepa emuchina. Izvi zvinoderedza nguva yekudzikira, mari yekugadzirisa, uye nyaya dzemhando yepamusoro dzine chekuita nekunamira nekusvibiswa kwepitch.

Sodium Carboxymethyl Cellulose (CMC) inobata basa rakakosha mukupera kwakanyorova kwemaitiro ekugadzira mapepa, ichibatsira mukuvandudza kuchengetedza, kudhiraivha, kuumbwa, simba, zvivakwa zvepasi, uye kutonga kwezvinosvibisa. Yayo yakawanda-inoshanda zvimiro inoita kuti ive yakakosha yekuwedzera yekuvandudza bepa kunaka uye kuita mumapepa akasiyana mamakisi uye mashandisiro.
