CMC inoshandisa muIndasitiri yePepa
Carboxymethylcellulose (CMC) inoshandiswa zvakanyanya muindasitiri yemapepa nekuda kwezvimiro zvayo zvakasiyana-siyana sepolymer inonyungudika nemvura. Inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muchirimwa masero madziro, kuburikidza nemakemikari ekuchinja maitiro anounza mapoka ecarboxymethyl. CMC inoshandiswa mumatanho akasiyana-siyana ekugadzira mapepa kuvandudza zvimiro zvepepa uye kuwedzera kushanda kwemaitiro ekugadzira. Heano akati wandei mashandisiro akakosha eCMC muindasitiri yemapepa:
- Kukura Kwepamusoro:
- CMC inoshandiswa seyepamusoro saizi mumiriri mukugadzira mapepa. Inonatsiridza zvimiro zvepapepa, senge kusamira kwemvura, kudhindwa, uye inki kugamuchira. CMC inoumba firimu rakatetepa papepa repamusoro, richibatsira kune zvirinani kudhinda mhando uye kuderedza ingi kupinda.
- Kukura Kwemukati:
- Pamusoro pekuyera kwepamusoro, CMC inoshandiswa seyemukati saizi mumiriri. Inosimudzira kuramba kwebepa kupinda mukati mezvinwiwa, kusanganisira mvura uye ingi dzekudhinda. Izvi zvinobatsira kusimba uye kusimba kwepepa.
- Kuchengeta uye Kubatsira Kwemvura:
- CMC inoita sekuchengetedza uye dhiraivha yekubatsira panguva yekugadzira mapepa. Inovandudza kuchengetwa kwefibers nezvimwe zvinowedzera mupepa repepa, zvichiita kuti zvive nani kuumbwa uye kuwedzera simba remapepa. CMC inobatsirawo mukudhiraivha, kuderedza nguva inotora kuti mvura ibviswe papepa repepa.
- Wet-End Additive:
- CMC inowedzerwa kumagumo akanyorova ekugadzira mapepa seyamuro yekuchengetedza uye flocculant. Inobatsira kudzora kuyerera uye kugovera fiber mupepa slurry, kuvandudza kushanda kwemushini wemapepa.
- Kudzora kwePulp Viscosity:
- CMC inoshandiswa kudzora viscosity ye pulp mune papermaking process. Izvi zvinogonesa kugoverwa kwakafanana kwemafibhi uye zvinowedzera, kukurudzira zvirinani kuumbwa kwepepa uye kuderedza njodzi yekukanganiswa kwemapepa.
- Simba Rakavandudzwa:
- Kuwedzerwa kweCMC kunobatsira kune simba zvivakwa zvepepa, kusanganisira kusimba kwesimba uye kuputika simba. Izvi zvakanyanya kukosha pakugadzira mapepa ane kusimba kwakawedzerwa uye kuita.
- Coating Additive:
- CMC inoshandiswa sechinhu chinowedzera mukuputira maumbirwo emapepa akaputirwa. Inobatsira kune rheology uye kugadzikana kwekuputira, kuvandudza kutsetseka uye kudhindwa kwemhando yemapepa akaputirwa.
- Kudzora kwePulp pH:
- CMC inogona kushandiswa kudzora pH yekumisikidza pulp. Kuchengetedza iyo yakakodzera pH level kwakakosha pakugadzirisa mashandiro eakasiyana ekugadzira mapepa makemikari.
- Kugadzira uye Sheet Uniformity:
- CMC inobatsira mukuvandudza kuumbwa uye kufanana kwemapepa mapepa. Inobatsira kudzora kugoverwa kwefiber uye zvimwe zvikamu, zvichiita kuti mapepa ane zvinhu zvinowirirana.
- Retention Rubatsiro rweMafirita uye Zvekuwedzera:
- CMC inoshanda seyamuro yekuchengetedza kune mafirita uye zvimwe zvekuwedzera mukugadzira mapepa. Inosimudzira kuchengetwa kwezvinhu izvi mubepa, zvichitungamira mukudhinda kuri nani uye kunaka kwebepa rose.
- Environmental Benefits:
- CMC ndeye biodegradable uye ine hushamwari nharaunda yekuwedzera, inopindirana neiyo indasitiri inotarisana nemaitiro akasimba.
Muchidimbu, carboxymethylcellulose (CMC) inoita basa rakakosha muindasitiri yemapepa, ichibatsira mukuvandudzwa kwezvivakwa zvemapepa, kugona kwemaitiro ekugadzira, uye kunaka kwese kwezvigadzirwa zvemapepa. Mashandisirwo ayo akasiyana-siyana mukuyera kwepasi, saizi yemukati, rubatsiro rwekuchengetedza, uye mamwe mabasa anoita kuti ive yekuwedzera yakakosha mumatanho akasiyana ekugadzira mapepa.
