Carboxymethyl Cellulose Sodium yePepa Coating

Carboxymethyl Cellulose Sodium (CMC) inowanzo shandiswa mumapepa ekuputira maapplication nekuda kweiyo yakasarudzika zvimiro. Heano mashandisirwo eCMC mukuputira mapepa:

1. Binder: CMC inoshanda sebhainda mumapepa ekuputira, ichibatsira kunamatira pigment, fillers, uye zvimwe zvinowedzera pabepa. Iyo inoumba yakasimba uye inoshanduka firimu pakuomeswa, inosimudzira kunamatira kwezvikamu zvekuputira kune substrate yepepa.
2. Thickener: CMC inoshanda seyakakora mumiriri mukuputira maumbirwo, kuwedzera viscosity uye kuvandudza rheological zvimiro zvemusanganiswa wekuputira. Izvi zvinobatsira kudzora kushandiswa kwekuvhara uye kuvhara, kuve nechokwadi chekugovera yunifomu ye pigment uye additives papepa repamusoro.
3. Kukura Kwepamusoro: CMC inoshandiswa mukugadzira saizi yepasi kuvandudza zvimiro zvepepa, senge kutsvedzerera, kugashira inki, uye kudhinda. Inowedzera kusimba kwepamusoro uye kuoma kwepepa, kuderedza guruva nekuvandudza runnability pamichina yekudhinda.
4. Kudzorwa Porosity: CMC inogona kushandiswa kudzora porosity yepepa rekuputira, kudzora kupinda kwezvinwiwa uye kudzivirira inki kubuda-kuburikidza mukudhinda maapplication. Iyo inoumba chipingamupinyi chivharo papepa repamusoro, inosimudzira inki kubata uye kubereka kwemavara.
5. Kuchengeta Mvura: CMC inoshanda sechinhu chekuchengetedza mvura mukugadzira maumbirwo, kudzivirira kunyudzwa kwemvura nekukurumidza nepepa substrate uye kubvumira nguva yakavhurika yakawedzerwa panguva yekuputira. Izvi zvinowedzera kuvhara kufanana uye kunamatira kune pepa pamusoro.
6. Optical Brightening: CMC inogona kushandiswa pamwe chete neoptical brightening agents (OBAs) kuvandudza kupenya uye kuchena kwemapepa akavharidzirwa. Inobatsira kuparadzira maOBAs zvakaenzana mukugadzirisa kwekuputira, kuwedzera maitiro emaziso epepa uye kuwedzera kukwezva kwayo.
7. Kuwedzeredzwa Hunhu Hwekudhinda: CMC inobatsira kune iyo yese kudhindwa mhando yemapepa akavharidzirwa nekupa yakatsetseka uye yakafanana nzvimbo yekuisa inki. Inonatsiridza inki holdout, color vibrancy, uye print resolution, zvichikonzera kupinza mifananidzo uye zvinyorwa.
8. Mabhenefiti Ezvakatipoteredza: CMC inogara yakagadzikana uye ine eco-inoshamwaridzika imwe nzira yekugadzira mabhainda uye makobvu anowanzo shandiswa mumapepa ekuputira. Iyo biodegradable, inovandudzwa, uye inotorwa kubva kune yakasikwa cellulose masosi, ichiita kuti ive yakakodzera kune zvakatipoteredza vanogadzira mapepa ekugadzira.

Carboxymethyl Cellulose Sodium (CMC) ndeyekuwedzera kune zvakasiyana-siyana iyo inosimudzira mashandiro uye kunaka kwemapepa ekuputira. Basa rayo sebinder, thickener, pamusoro saiziing agent, uye porosity modifier inoita kuti ive yakakosha mukugadzirwa kwemhando yepamusoro mapepa akavharidzirwa ekushandisa kwakasiyana, kusanganisira kudhinda, kurongedza, uye mapepa ehunyanzvi.
