Nei CMC ichiita basa rakakosha muIndasitiri yeKugadzira Pepa

Sodium carboxymethyl cellulose (CMC) inoita basa rakakosha muindasitiri yekugadzira mapepa nekuda kweiyo yakasarudzika zvivakwa uye kushanda kwayo. Ichi ndicho chikonzero CMC yakakosha mukugadzira mapepa:

1. Kuchengeta uye Kubatsira Kwemvura: CMC inoita sekuchengetedza uye rubatsiro rwekudhonza mukugadzira mapepa. Inovandudza kuchengetwa kwezvikamu zvakanaka, fiber, uye zvinowedzera mupepa repepa, kudzivirira kurasikirwa kwavo panguva yekugadzira nekuvandudza mapepa ekuumbwa uye kufanana. CMC zvakare inokwidziridza dhiraivha nekuwedzera mwero wekuyerera kwemvura kuburikidza nepepa muchina waya mesh, kuderedza nguva inodiwa pakugadzira mapepa uye kuomesa.
2. Yemukati Sizing Agent: CMC inoshanda seyemukati saizi mumiriri mumapepa maumbirwo, ichipa mvura kuramba uye kugashira inki kupepa rakapedzwa. Iyo inoshambadza pane cellulose fiber uye mafirita zvidimbu, ichigadzira hydrophobic barriers inodzinga mamorekuru emvura uye inoderedza kupinda kwezvinwiwa muchimiro chepepa. CMC-yakavakirwa saizi maumbirwo anovandudza kudhindwa, inki kubata, uye kugadzikana kwedimensional yezvigadzirwa zvemapepa, zvichivandudza kukodzera kwazvo kweakasiyana kudhinda nekunyora maapplication.
3. Surface Sizing Agent: CMC inoshandiswa seyepamusoro saizi mumiriri kusimudzira zvimiro zvepepa, senge kutsetseka, kupenya, uye kudhinda. Inoumba firimu yakaonda pamusoro pepepa repepa, ichizadza kusakanganiswa kwepamusoro uye kuderedza porosity. Izvi zvinovandudza kusimba kwepamusoro, inki kubata, uye kudhindwa kwemhando yebepa, zvichiita kuti rive rakapinza, rine simba rakadhindwa mifananidzo uye zvinyorwa. CMC-yakavakirwa pamusoro saizi maumbirwo zvakare inovandudza kutsetseka kwepamusoro uye kumhanya kwebepa pakudhinda nekushandura michina.
4. Wet End Additive: Mumagumo akanyorova emuchina wepepa, CMC inoshanda seyakanyorova yekupedzisira yekuwedzera kuvandudza mapepa ekuumbwa uye simba repepa. Iyo inosimudzira flocculation uye kuchengetwa kwefiber uye mafirita, zvichitungamira kune zvirinani mashizha kuumbwa uye kufanana. CMC inowedzerawo simba rekubatanidza pakati pemafayibha, zvichikonzera kusimba kwebepa repamusoro, kuramba kubvarura, uye kuputika kwesimba. Izvi zvinovandudza huwandu hwese uye kusimba kwechigadzirwa chepepa chakapedzwa.
5. Pulp Dispersant uye Agglomerate Inhibitor: CMC inoshanda sepulp dispersant uye agglomerate inhibitor mukugadzira mapepa, kudzivirira kuunganidzwa uye kudzokororwa kweselulosi fiber uye faindi. Iyo inoparadzira fiber uye faindi zvakaenzana mukati meseti yemapepa, ichidzikisa fiber bundling uye kunatsiridza pepa kuumbwa uye kufanana. CMC-based dispersants inosimudzira kugona kwe pulp kugadzirisa uye kuderedza kuitika kwekuremara senge mavara, maburi, uye mitsetse mupepa rakapera.
6. Surface Coating Binder: CMC inoshandiswa sebhainda mupamusoro coating maumbirwo emapepa akavharwa uye mapepa. Inosunga pigment particles, zvakadai se calcium carbonate kana kaolin, kumusoro kwepepa substrate, ichiita jira rakatsetseka, rakafanana. CMC-based coatings inovandudza kudhindwa, kupenya, uye maziso emeso emapepa akavharwa, achivandudza chitarisiko chavo uye kushambadzira mumhando yepamusoro yekudhinda uye kurongedza maapplication.
7. Kusagadzikana Kwezvakatipoteredza: CMC inopa mabhenefiti ezvakatipoteredza muindasitiri yekugadzira mapepa seyakagadziriswazve, biodegradable, uye isiri-chepfu yekuwedzera. Inotsiva synthetic sizing agents, dispersants, uye coating binders, kuderedza kukanganiswa kwezvakatipoteredza kwekugadzira mapepa uye kuraswa. CMC-yakavakirwa mapepa zvigadzirwa zvinodzokororwa uye compostable, zvichibatsira kune inoenderera masango maitiro uye denderedzwa hupfumi zvirongwa.

sodium carboxymethyl cellulose (CMC) inoita basa rinokosha muindasitiri yekugadzira mapepa nekuvandudza kuumbwa kwemapepa, simba, zvivakwa zvepasi, kudhindwa, uye kuchengetedza kwezvakatipoteredza. Hunhu hwayo hunoita mabasa akawanda hunoita kuti ive yekuwedzera yakasiyana-siyana yekusimudzira hunhu, kuita, uye kukwikwidza kwemusika kwezvigadzirwa zvemapepa nemapepa mumapepa akasiyana siyana.
