Ko te kounga o te carboxymethyl cellulose CMC e whakawhirinaki ana ki te otinga o te hua. Mena he mārama te otinga o te hua, he iti ake ngā matūriki tiēre, he iti ake ngā muka kore utu, ā, he iti ake ngā ira pango o ngā poke. Ko te tikanga, ka taea te whakatau he tino pai te kounga o te carboxymethyl cellulose.
Te Whakarewatanga me te Mararatanga o ngā Hua Carboxymethyl Cellulose
Whakaranua tika te carboxymethylcellulose ki te wai hei whakarite i te wairewa kapia mō te whakamahi. I te whirihoranga o te paru carboxymethyl cellulose, whakamahia he taputapu whakaoho hei tāpiri i tētahi nui o te wai mārama ki roto i te tāke puranga. Whai muri i te tahuritanga o te taputapu whakaoho, tauhiuhia mārire, ōrite hoki te carboxymethyl cellulose ki roto i te tāke puranga, ka whakaoho tonu kia tino honoa te carboxymethyl cellulose me te wai, ā, ka taea te rewa katoa te carboxymethyl cellulose.
I te whakarewatanga o te carboxymethyl cellulose, ko te kaupapa o te mararatanga ōrite me te whakaoho tonu ko te "ārai i te whakapiripiri, te whakaiti i te nui o te carboxymethyl cellulose kua rewa, me te whakanui ake i te tere whakarewatanga o te carboxymethyl cellulose". I te nuinga o te wā, he poto ake te wā whakaoho i te wā e hiahiatia ana kia rewa katoa te carboxymethylcellulose.
I te wā e whakaoho ana, ki te mea ka horapa ōrite te carboxymethyl cellulose ki roto i te wai, ā, kāore he puranga nui e kitea ana, ā, ka taea e te carboxymethyl cellulose me te wai te uru me te hanumi, ka taea te whakamutu i te whakaoho. Ko te tere whakaranu i te nuinga o te wā kei waenga i te 600-1300 rpm, ā, ko te wā whakaoho ka whakahaeretia i te nuinga o te wā mō te 1 hāora.
Ko te whakatau i te wā e hiahiatia ana mō te rewa katoa o te carboxymethyl cellulose e ahu mai ana i ngā mea e whai ake nei:
1. Kua honoa katoatia te carboxymethyl cellulose me te wai, ā, kāore he wehenga totoka-wai i waenganui i a rāua.
2. Kei te āhua ōrite te paraoa i muri i te whakaranu, ā, he maeneene, he maeneene hoki te mata.
3. Kāore he tae o te whakapiri i konatunatua, he mārama hoki, ā, kāore he kirikiri i roto i te whakapiri. E 10 ki te 20 hāora te roa hei whakanoho i te carboxymethylcellulose ki roto i te tāke whakaranu, ka whakaranua ki te wai kia memeha rawa te carboxymethylcellulose. Hei whakanui ake i te tere o te whakaputa me te penapena wā, kei te whakamahia ngā homogenizers, ngā colloidal grinding rānei hei tere hora i ngā hua.
