Sodium carboxymethylcellulose (CMC) bụ ngwakọta kemịkalụ kemịkalụ nwere ngwa zuru ebe niile na ụlọ ọrụ dị iche iche, ọkachasị na ụlọ ọrụ na-emepụta akwụkwọ. Nke a na-enweta carbohydrate sitere na cellulose, nke bụ polymer eke dị na mgbidi cell osisi. A na-emepụta CMC site na imeghachi cellulose na sodium hydroxide na chloroacetic acid ma ọ bụ nnu sodium ya. Ihe na-esi na ya pụta bụ mmiri na-agbaze ma nwee ihe pụrụ iche nke na-eme ka ọ baa uru n'ọtụtụ ngwa.
1.Pulp Nkwadebe:
A na-ejikarị CMC eme ihe dị ka akụkụ na njedebe mmiri nke usoro nhazi akwụkwọ. Ọ na-enyere aka na mgbasa nke eriri na ihe mgbakwunye ndị ọzọ n'ime mmiri, na-eme ka e guzobe slurry pulp homogeneous.
Ike ya dị elu na-ejigide mmiri na-enyere aka n'ịnọgide na-adịgide adịgide nke pulp slurry, na-eme ka ịdị n'otu na nhazi akwụkwọ.
2. Njide na igbapu:
Otu n'ime isi ihe ịma aka dị n'ichepụta akwụkwọ bụ ịba ụba nke njide eriri na ihe mgbakwunye ma na-ekpochapụ mmiri nke ọma na pulp. CMC na-enyere aka dozie ihe ịma aka a site n'ịkwalite ma njigide na njide mmiri.
Dị ka ihe enyemaka njide, CMC na-ejikọta eriri na mma, na-egbochi ọnwụ ha n'oge e guzobere akwụkwọ mpempe akwụkwọ.
CMC na-eme ka mmịpụta dị mma site n'ịba ụba nke a na-ewepụ mmiri site na pulp, na-eduga n'iwepu mmiri ngwa ngwa na ngwa ngwa igwe akwụkwọ dị elu.
3. Nkwalite ike:
CMC na-enye aka na njirimara ike nke akwụkwọ, gụnyere ike nkwụsị, nkwụsị anya mmiri, na ike mgbawa. Ọ na-etolite netwọk n'ime matriks akwụkwọ, na-ewusi usoro ahụ ike nke ọma ma na-eme ka akụrụngwa ya dịkwuo elu.
Site n'ịkwalite ike akwụkwọ, CMC na-enye ohere maka ịmepụta akara akwụkwọ dị ntakịrị na-enweghị ịchụ àjà, si otú a na-eme ka ego na-echekwa ego na ịrụ ọrụ nke ọma.
4. Nhazi elu:
Nhazi nke dị n'elu bụ nzọụkwụ dị oke egwu n'ime akwụkwọ nke gụnyere itinye obere ihe na-eme ka ọ dị mkpa n'elu akwụkwọ ahụ iji meziwanye nbipụta ya, ire ụtọ, na nkwụsị mmiri.
A na-eji CMC n'ọrụ dị ka onye na-emepụta ihe n'elu n'ihi ihe na-emepụta ihe nkiri ya na ike ịkwalite ike elu na ire ụtọ. Ọ na-etolite mkpuchi otu n'elu akwụkwọ, na-ebute njide ink ka mma yana ịdị mma bipụta.
5.Retention Aid maka Fillers na pigments:
N'ime akwụkwọ, a na-agbakwunye ihe ndochi na pigmenti iji kwalite njirimara akwụkwọ dị ka opacity, nchapụta, na mbipụta. Otú ọ dị, ihe mgbakwunye ndị a nwere ike ịdị mfe ịnweta mmiri mmiri n'oge usoro nhazi akwụkwọ.
CMC na-eje ozi dị ka ihe enyemaka njide maka ndị na-ejuputa na pigmenti, na-enyere aka ịkwado ha n'ime matrix akwụkwọ ma belata ọnwụ ha n'oge nhazi na ihicha.
6. Njikwa Njirimara Rheological:
Rheology na-ezo aka n'omume na-asọpụta nke mmiri, gụnyere pulp slurries, n'ime usoro nhazi akwụkwọ. Ịchịkwa ihe ndị rheological dị mkpa maka imeziwanye usoro nhazi na àgwà ngwaahịa.
CMC na-emetụta rheology nke pulp slurries site n'ịgbanwe viscosity ha na njiri mara ha. Enwere ike iji ya dozie akụrụngwa rheological nke pulp ahụ ka ọ dabara ihe achọrọ nhazi, dị ka imeziwanye igwe na-agba ọsọ na nhazi mpempe akwụkwọ.
7. Ihe gbasara gburugburu ebe obibi:
A na-ewerekarị sodium carboxymethylcellulose dị ka enyi na enyi gburugburu ebe obibi, n'ihi na ọ na-esite na isi mmalite cellulose na-emegharịghachi ma bụrụkwa ihe na-emebi emebi.
Ojiji ya n'ichepụta akwụkwọ nwere ike inye aka na mmepe nke ngwaahịa akwụkwọ na-adigide site n'ime ka usoro mmepụta ihe na-arụ ọrụ nke ọma na imeziwanye arụmọrụ ngwaahịa.
sodium carboxymethylcellulose (CMC) na-arụ ọrụ dị iche iche na ụlọ ọrụ na-emepụta akwụkwọ, na-eje ozi dị ka ihe mgbakwunye na-eme ka akụkụ dị iche iche nke usoro mmepụta akwụkwọ dịkwuo mma. Site na nkwadebe pulp ruo n'ókè nke elu ala, CMC na-enye aka n'ịkwalite arụmọrụ usoro, ogo ngwaahịa, na nkwado gburugburu ebe obibi. Ngwakọta ya pụrụ iche na-eme ka ọ bụrụ ihe dị mkpa maka ndị na-ede akwụkwọ na-achọ ịkwalite arụmọrụ yana izute ihe na-agbanwe agbanwe nke ahịa.
