CMC Product Introduction for Reactive Printing Paste

1. Sodium Carboxymethyl Cellulose
Reactive printing phala ndi chochokera ku ether kapangidwe kake posintha ma cellulose achilengedwe.Ndi guluu wosungunuka m'madzi womwe ukhoza kusungunuka m'madzi ozizira ndi madzi otentha.Njira yake yamadzimadzi imakhala ndi ntchito zogwirizanitsa, kukhuthala, kufalitsa, kuyimitsa ndi kukhazikika.

Reactive printing phala ndi chopangidwa ndi sodium carboxymethyl cellulose yokhala ndi etherification yayikulu.Njira yapaderayi imapangitsa kuti gulu lake loyamba la hydroxyl lilowe m'malo mwake, kuti asatengeke ndi utoto wokhazikika.

Monga thickener wa kusindikiza phala, zotakasika kusindikiza phala akhoza kukhazikika mamasukidwe akayendedwe, kusintha fluidity wa phala, kumapangitsanso luso hydrophilic utoto, kupanga utoto yunifolomu ndi kuchepetsa kusiyana mtundu;panthawi imodzimodziyo, mukutsuka mutatha kusindikiza ndi utoto, mlingo wotsuka ndi wapamwamba, Nsaluyo imakhala yofewa kukhudza.

2. Kuyerekeza makhalidwe a zotakasika kusindikiza phala ndi sodium alginate
2.1 Paste rate

Poyerekeza ndi sodium alginate, zotakasika kusindikiza phala ali apamwamba mamasukidwe akayendedwe, kaya ntchito yokha kapena osakaniza thickeners ena, akhoza bwino kuchepetsa mtengo wa phala;kawirikawiri, yogwira kusindikiza phala Mlingo ndi 60-65% yokha ya sodium alginate.

2.2 Kutulutsa kwamitundu ndi kumva

Zokolola zamtundu wa phala losindikizira lokonzedwa ndi phala losindikizira lokhazikika ngati thickener ndi lofanana ndi la sodium alginate, ndipo nsaluyo imakhala yofewa pambuyo pa desizing, yomwe imakhala yofanana ndi ya sodium alginate paste.

2.3 Matani kukhazikika

Sodium alginate ndi colloid yachilengedwe, yomwe imakhala yosalolera bwino kwa tizilombo tating'onoting'ono, nthawi yochepa yosungiramo phala lamtundu, ndipo ndi yosavuta kuwononga.Kukhazikika kwa zinthu wamba za sodium carboxymethyl cellulose ndizopambana kwambiri kuposa sodium alginate.Zopangira zosindikizira zosindikizira zasinthidwa ndi njira yapadera, ndipo kukana kwawo kwa electrolyte kuli bwino kuposa mankhwala wamba a sodium carboxymethyl cellulose.Panthawi imodzimodziyo, amakhala ogwirizana bwino ndi othandizira mankhwala ndi utoto, ndipo sizosavuta kuti awonongeke komanso awonongeke panthawi yosungira.Kukhazikika kwamankhwala ndikwabwinoko kuposa sodium alginate.

2.4 Rheology (yowonjezera)

Onse sodium alginate ndi CMC ndi pseudoplastic zamadzimadzi, koma sodium alginate ali otsika kukhuthala structural kukhuthala ndi mkulu PVI mtengo, kotero si koyenera kuzungulira (lathyathyathya) chophimba kusindikiza, makamaka high-mesh chophimba kusindikiza;zotakasika kusindikiza phala mankhwala ndi mkulu structural mamasukidwe akayendedwe , PVI mtengo ndi za 0,5, zosavuta kusindikiza mizere bwino kusindikiza.Kuphatikiza kwa sodium alginate ndi yogwira kusindikiza phala akhoza kukwaniritsa zofunika kwambiri rheological kusindikiza phala
