CMC imagwiritsa ntchito Paints and Coatings Viwanda

Penta kalasi carboxymethyl cellulose sodiumali kukhuthala kwabwino, kufalikira ndi kukhazikika, kumatha kupititsa patsogolo kukhuthala ndi rheology ya zokutira, kotero zimagwiritsidwa ntchito kwambiri pazovala zosiyanasiyana, zokutira za latex, zokutira zamadzi zakunja ndi zamkati, zokutira zoponyera ndi zina zotero.

Kugwiritsa ntchito nthawi yomweyoutoto kalasi carboxymethyl cellulose:

The otchedwa yomweyo njira zikutanthauza kuti CMC ufa akhoza kumwazikana ndi kusungunuka mwamsanga njira amadzimadzi kutentha firiji, amene ali osiyana ndi ochiritsira mtundu wa CMC kusungunuka pang'onopang'ono (mtundu ochiritsira wa CMC ayenera osachepera 2-3 maola mkulu- kuthamangitsa liwiro kuti kusungunuka kwathunthu). The mamasukidwe akayendedwe a nthawi ❖ kuyanika kalasi carboxymethyl mapadi CMC sadzafika nthawi yomweyo mamasukidwe akayendedwe ake enieni ndi kuvunda mofulumira ufa, ndipo adzakhala mu mphindi 10-15 pambuyo kuvunda kwa mamasukidwe akayendedwe, mapangidwe kukhuthala kwenikweni akhoza kukwaniritsa colloid. . Kuphatikiza apo, kukhazikika kwa colloid kwa CMC pompopompo ndikwabwinoko kuposa CMC wamba yokhala ndi mawonekedwe omwewo.

Instantzosungunukacarboxymethyl cellulose CMC imagwiritsidwa ntchito kwambiri mumitundu yonse ya zokutira zokhala ndi madzi, monga latex yoyera, utoto wa latex, putty, utoto wothandizira, utoto wamwala wachilengedwe, etc.

Ubwino wautoto kalasi carboxymethyl cellulose:

A) Kupaka sikunapangidwe ndipo kumatha kusungidwa kwa nthawi yayitali;

B) Itha kupereka zinthu zapadera zosungunula mwachangu zopangira zopaka m'magawo apadera;

C) Sinthani bwino rheology ya glaze slurry, yambitsani ntchito yonyezimira, ndikupanga glaze slurry mu chikhalidwe chobalalika chokhazikika;

D) Sinthani bwino mphamvu ya glaze ndi kusalala kuti mupewe kugwa;

E) Onetsetsani kuti ntchito yosindikizira pakupanga makina osindikizira, ndipo mawonekedwe osindikizidwa ndi omveka bwino komanso okongola;

F) Sipadzakhala kutsekereza mu kusindikiza glaze ndondomeko yosindikiza, CMC ali ndi madzi kusungunuka bwino ndipo pafupifupi palibe insoluble zinthu monga CHIKWANGWANI zosafunika;

Penta kalasiCMCNjira yothetsera carboxymethyl cellulose:

Theutoto grade carboxymethyl cellulose imasakanizidwa mwachindunji ndi madzi ndikukonzedwa kukhala guluu la phala kuti ligwiritsidwe ntchito mtsogolo. Mlingo wa kasinthidwe ❖ kuyanika carboxymethyl mapadi phala zomatira, choyamba ndi kusakaniza zosakaniza zomera mu yamphamvu kuti agwirizane ena kuchuluka kwa madzi oyera, poyera pansi pa chikhalidwe choyambitsa chipangizo, ❖ kuyanika mlingo wa carboxymethyl mapadi pang'onopang'ono ndi wogawana kuti zosakaniza mu yamphamvu. , yambitsani mosalekeza, pangani utoto wa carboxymethyl cellulose ndi kuphatikizika kwa mulingo wamadzi, carboxymethyl cellulose imatha kusungunuka mulingo wokutira. Pamene kusungunuka utotokalasi carboxymethyl mapadi, chifukwa wogawana kufalikira, ndi nthawi zonse oyambitsa, cholinga ndi "kupewa utoto kalasi carboxymethyl CHIKWANGWANI ndi madzi kukumana, agglomeration, agglomeration, kuchepetsa utoto kalasi carboxymethyl mapadi solubility vuto", ndi kusintha mlingo wa Kusungunuka kwa utoto kalasi carboxymethyl cellulose. Oyambitsa nthawi ndi utoto kalasi carboxymethyl mapadi wathunthu kuvunda nthawi si kugwirizana, ndi mfundo ziwiri, kawirikawiri kulankhula, oyambitsa nthawi ndi lalifupi kwambiri kuposa utoto kalasi carboxymethyl mapadi wathunthu kuvunda nthawi, nthawi yofunikira zimadalira mmene zinthu.

Kudziwa yogwira mtima nthawi pamaziko a: pamene carboxymethyl mapadi m'madzi wogawana omwazika, palibe zoonekeratu lalikulu mtanda chinthu, inu mukhoza kusiya oyambitsa, kuti carboxymethyl mapadi ndi madzi mu malo malo amodzi a malowedwe onse, maphatikizidwe.

Dziwani kuti carboxymethyl cellulose kutha kwathunthu kwa nthawi yofunikira pazifukwa izi:

(1) kalasi ya pentiCMCcarboxymethyl cellulose ndi madzi zimamangirizidwa kwathunthu, ndipo palibe kupatukana kwamadzi olimba pakati pawo;

(2) Phala losakanikirana limakhala lofanana, ndipo pamwamba pake ndi yosalala;

(3) Mtundu wa aleurone wosakanizidwa uli pafupi ndi wopanda mtundu komanso wowonekera, ndipo palibe chinthu cha granular mu aleurone. Kuyambira kalasi ya utotoCMCcarboxymethyl cellulose imayikidwa mu thanki yosakaniza ndi madzi, mpaka kalasi ya utotoCMCcarboxymethyl cellulose kusungunuka kwathunthu, nthawi yofunikira pakati pa maola 10 mpaka 20.
