I-Sodium Carboxymethyl Cellulose (CMC) iyi-anionic, i-chain eqondile, i-cellulose ether ye-cellulose, okususelwa kwemvelo ye-cellulose ne-chlororosetic acid ngokuguqulwa kwamakhembu. Isixazululo sayo samanzi sinemisebenzi yokuqina, ukwakha amafilimu, ukugcinwa kwamabhondi, ukugcinwa kwamanzi, ukuvikelwa kwama-ejenti, i-ejectific, i-ejenti, i-ejenti, i-ejenti, ipulasitiki, amapulasitiki, amakhemikhali, amakhemikhali nsuku zonke, amakhemikhali nsuku zonke imboni kanye nezinye izinkambu.

I-Sodium Carboxymethyl celtulose ngokuvamile iyisigaxa esiqinile, kwesinye isikhathi i-granular noma i-fibrous, elimhlophe noma elikhanyayo ngombala, i-macromolecular yamakhemikhali, inenkinga yamakhemikhali, ingancipha emanzini, angakwazi ukwakha isixazululo esibonakalayo ngokusobala okuphezulu. I-insoluble in the general organic solutions, njenge-ethanol, ether, chloroform kanye ne-benzene, kepha ingachithwa ngamanzi ngokuqondile, kepha i-solubelity isenkulu kakhulu, bese kuthi isixazululo esinamanzi sisesimweni esihle kakhulu. I-General Endaweni ejwayelekile zizinzile, ngoba inomunwe othile wamanzi kanye nomswakama, endaweni eyomile, ingagcinwa isikhathi eside.

Inqubo yokukhiqiza ①

1. Indlela Yamanzi Ephakathi

Inqubo yamalahle enamanzi iyinqubo yokuqala yokukhiqiza ekuhlinzekweni kwezimboni ze-sodium carboxymethyl cellulose. Kule nqubo, i-Alkali Cellulose kanye ne-ejenti ye-ejenti enze isisombululo esinamanzi aqukethe i-oxygen oxygen oxide oxide, futhi amanzi asetshenziswa njengendlela yokusabela kwinqubo yokusabela, ngaphandle kwezinhlelo ze-organic.

2. Indlela ye-Solvent

Indlela ye-Solvent yindlela ye-organic solvent, okuyinqubo yokukhiqiza eyenzelwe ngesisekelo sendlela yamanzi aphakathi nendawo yokubuyisela amanzi nge-organic solvent ye-organic njengendlela yokusabela. Inqubo ye-alkalization kanye nokuthezeka kwe-Alkali Cellulose ne-monochlororosetic acid ku-organic solvent. Ngokuya ngenani le-Medial Medial, lingahlukaniswa ngendlela yokuxova kanye nendlela yokubhukuda ye-slurry. Inani le-organic solvent elisetshenziswe kwindlela yokuphamba likhulu kakhulu kunaleyo ndlela yokugoba, kanye nenani le-organic solvent elisetshenziswe ngendlela yevolumu ngesilinganiso se-purliose yisilinganiso sesisindo sethamo lenani lesembozo senani lenani lesembozo. Lapho i-sodium carboxymetyl cellulose ilungiselelwe indlela yokubhukuda ye-slurry, ukusabela okuqinile kusesimweni se-slurry noma ukumiswa ohlelweni, ngakho-ke indlela yokubhukuda ye-slurry ibizwa ngendlela yokumiswa.

3. Indlela E-Slurry

Indlela yeSlurry ubuchwepheshe bamuva bokukhiqiza i-sodium carboxymethyl cellulose. Indlela E-Slurry ayikwazi ukukhiqiza kuphela i-sodium purneity carboxylls purkuluel, kodwa futhi ikhiqiza i-sodium carboxymethyl celtule ngesilinganiso esiphezulu sokufakwa esikhundleni kanye nokufakwa esikhundleni okufanayo. Inqubo yokukhiqiza ye-Slurry Method icishe kanjena: I-pulp yekotini ebilokhu ifakwe ku-powder kuthunyelwa emshinini we-alkalical ifakwe ngotshwala be-vertical alkalizing, kanti izixazululo ze-sodium hydroxide zingezwe ngenkathi izinga lokushisa le-alkali. Ngemuva kwe-alkalization, okuqukethwe kuphonswe emshinini okuthe xaxa, futhi isixazululo sotshwala se-isopropyl se-chloropyl se-chloropyl acid sengezwe, futhi izinga lokushisa elithe xaxa lingaba ngu-65 ℃. Ngokusho kokusetshenziswa komkhiqizo othize kanye nezidingo zekhwalithi, ukugxilwa kwekhwalithi, isikhathi se-alkalization, inani le-ejenti yokuphelisa kanye nesikhathi sokuthepha nezinye izingqinamba zenqubo zingalungiswa.

② Ububanzi besicelo

1. I-CMC ayigcini nje kuphela i-emulsizer stabilizer kanye nokuqina ezihlelweni zokudla, kepha futhi inokuqina okuhle kakhulu nokuncibilika, futhi kungathuthukisa ukunambitheka komkhiqizo futhi kuthuthukise isikhathi sokugcina.

2

I-3. Ekubizeni uwoyela kungasetshenziselwa ukuvikela imithombo kawoyela njenge-stud stabilizer, i-ejenti yokugcinwa kwamanzi, inani lemithombo ngayinye yamafutha yi-2 ~ 3t Wells, i-Wells 5 ~ 6t.

4. Isetshenziswa embonini yezindwangu njenge-ejenti yezandla, ukuphrinta nokudaya okukhulu, ukuphrinta kwendwangu kanye nokuqedwa kwe-stiffering.

I-5. Isetshenziswa njenge-ejenti yokulwa nama-ejenti, i-emulsifier, ehlakazekile, i-ejenti, inamathela, ingenza ingxenye eqinile yopende isatshalaliswe isikhathi eside ku-solvent, ukuze upende akwenziwanga isikhathi eside, kodwa futhi futhi esetshenziswe ku-tutty.

6. Njenge-flocculant ekususweni kwama-calcium ion kune-sodium gluconate ngempumelelo, njengokushintshana kwe-coation, umthamo wokushintshana ofinyelela ku-1.6ml / g.

7. Embonini yamaphepha asetshenziswa njenge-ejenti ye-ting ephepheni, kungawuthuthukisa kakhulu amandla owomile namandla amanzi okumelana namaphepha kanye nokuphikiswa kwamafutha, ukuntywilwa kwamanzi kanye nokumelana kwamanzi.

8. Njenge-hydrosol kwizimonyo, esetshenziswa njenge-ejenti yokuqina ekuxubekeni, umthamo wayo cishe ngo-5%.
