Hunhu hwe sodium carboxymethyl cellulose zvigadzirwa

Carboxymethyl cellulose (Sodium Carboxymethyl Cellulose) inonzi CMC, inzvimbo inoshanda colloid polymer musanganiswa, imhando yekunhuhwirira, isinganakidze, isina muchetura mvura-inonyungudika cellulose inotorwa, inogadzirwa nedonje inonyudza kuburikidza nemuviri-kemikari kurapwa. Iyo inowanikwa organic cellulose binder imhando ye cellulose ether, uye sodium yayo munyu inowanzo shandiswa, saka zita rayo rakazara rinofanira kunzi sodium carboxymethyl cellulose, kureva CMC-Na.

Senge methyl cellulose, carboxymethyl cellulose inogona kushandiswa seyakagadziriswa yezvinhu zvinoramba uye sechibhainda chenguva pfupi yezvinhu zvinoramba.

Sodium carboxymethyl cellulose is a synthetic polyelectrolyte, saka inogona kushandiswa se dispersant uye stabilizer kune refractory slurries uye castables, uye zvakare iri yechinguvana yakakwirira-inoshanda organic binder. Ine zvinotevera zvakanakira:

1. Carboxymethyl cellulose inogona kunyatsoshambadzirwa pamusoro pezvimedu, kupinda mukati uye kubatanidza zvimedu zvakanaka, kuitira kuti simba repamusoro refractory muviri riwanikwe;

2. Sezvo carboxymethyl cellulose iri anionic polymer electrolyte, inogona kuderedza kupindirana pakati pezvimedu mushure mekushambadza pamusoro pezvikamu, uye kuita basa re dispersant uye inodzivirira colloid, nokudaro kuvandudza density uye simba rechigadzirwa uye kuderedza. mushure-kutsva. Inhomogeneity yehurongwa hwesangano;

3. Kushandisa carboxymethyl cellulose sebinder, hapana madota mushure mekupisa, uye kune zvishoma zvishoma-zvinonyunguduka zvinhu, izvo zvisingakanganisi kushandiswa kwekushisa kwechigadzirwa.

Product Features

1. CMC ichena kana zvishoma yero fibrous granular poda, isinganakidze, isinganhuwi, isina chepfu, inonyungudika nyore mumvura, uye inoumba sparent viscous colloid, mhinduro haina kwayakarerekera kana zvishoma alkaline. Inogona kuchengetwa kwenguva yakareba pasina kuora, uye zvakare yakagadzikana pasi pekushisa kwakadzika uye chiedza chezuva. Zvisinei, nekuda kwekukurumidza kuchinja kwekushisa, acidity uye alkalinity yemhinduro inoshanduka. Pasi pesimba re ultraviolet radiation uye microorganisms, ichaitawo kuti hydrolysis kana oxidation, viscosity yemhinduro inoderera, uye kunyange mhinduro ichasvibiswa. Kana mhinduro yacho ichida kuchengetwa kwenguva yakareba, zvinodzivirira zvakakodzera zvakadai se formaldehyde, phenol, benzoic acid, organic mercury compounds, nezvimwewo zvinogona kusarudzwa.

2. CMC yakafanana nedzimwe polymer electrolytes. Kana ichinyunguduka, inotanga kubudisa chiitiko chekuputika, uye zvikamu zvinonamatira kune mumwe nemumwe kuti zvigadzire firimu kana viscose, izvo zvinoita kuti zvisakwanise kupararira, asi zvinopera zvishoma nezvishoma. Nokudaro, paunenge uchigadzirira mhinduro yaro yemvura, kana zvimedu zvingave zvakaenzana zvakanyoroveswa kutanga, chiyero chekuparara chinogona kuwedzerwa zvakanyanya.

3. CMC is hygroscopic. Mumhepo, avhareji yemvura yemukati yeCMC inowedzera nekuwedzera kwekushisa kwemhepo uye inoderera nekuwedzera kwekushisa kwemhepo. Kana avhareji tembiricha yekamuri tembiricha iri 80% -50%, yakaenzana mvura yemukati iri pamusoro pe26%, uye chigadzirwa mvura inokwana 10% kana pasi. Naizvozvo, kurongedza kwechigadzirwa uye kuchengetedza kunofanirwa kutarisisa kune hunyoro-uchapupu.

4. Zingi, mhangura, mutobvu, aruminiyamu, sirivha, simbi, tini, chromium uye mamwe heavy metal munyu anogona precipitate CMC aqueous mhinduro. Kunze kwemunyu-based lead acetate, iyo precipitate inogona kunyungudika zvakare mu sodium hydroxide kana ammonium hydroxide solution. .

5. Organic kana inorganic acids inokonzerawo kunaya kune mhinduro yechigadzirwa ichi. Chiitiko chekunaya kwemvura chinosiyana nerudzi uye kusungirirwa kweasidhi. Kazhinji, kunaya kwemvura kunoitika kana pH iri pasi pe2.5, uye inogona kudzoserwa mushure mekusarereka nealkali.

6. Mumunyu wakadai se calcium, magnesium uye tafura munyu, haina mvura inonaya paCMC solution, asi inokanganisa kuderedzwa kwe viscosity.

7. CMC inowirirana nemamwe glue-soluble glues, softeners uye resins.

8. Mafirimu akatorwa kubva kuCMC, akanyudzwa muacetone, benzene, butyl acetate, carbon tetrachloride, castor oil, corn oil, ethanol, ether, dichloroethane, petroleum, methanol, methyl acetate, methyl ethyl acetate pakamuri tembiricha Ketone, toluene, turpentine, xylene, peanut oil, nezvimwewo zvinogona kusachinjwa mukati memaawa makumi maviri nemana
