Mmetụta nke Carboxymethyl Cellulose (CMC) na Njirimara nke Ceramic Slurry

Carboxymethyl cellulose (CMC) bụ polymer soluble mmiri nke ewepụtara na cellulose nke nwere ọtụtụ ngwa dị iche iche na ụlọ ọrụ dị iche iche. N'ime ụlọ ọrụ ceramik, a na-ejikarị CMC eme ihe dị ka onye na-ekekọta na rheology modifier na seramiiki slurry formulations. Mgbakwunye nke CMC nwere ike imetụta njirimara nke seramiiki slurry, gụnyere viscosity ya, omume rheological, na nkwụsi ike. N'isiokwu a, anyị ga-atụle mmetụta nke CMC na Njirimara nke seramiiki slurry.

Viscosity

Mgbakwunye CMC na slurry seramiiki nwere ike ịbawanye viscosity ya nke ukwuu. Nke a bụ n'ihi ịdị arọ molekụla dị elu na ọkwa dị elu nke nnọchi nke CMC, nke na-eme ka viscosity dị elu ọbụna na obere mkpokọta. CMC na-arụ ọrụ dị ka ihe na-eme ka ọ dị arọ, na-abawanye viscosity nke seramiiki slurry ma na-eme ka ike ya dịgide n'elu ahụ seramiiki.

Omume Rheological

CMC nwekwara ike imetụta omume rheological nke seramiiki slurry. The rheology nke seramiiki slurry dị mkpa maka nhazi ya na arụmọrụ ya. Mgbakwunye nke CMC nwere ike ime ka omume na-egbuke egbuke, ebe viscosity nke slurry na-ebelata ka ọnụ ọgụgụ nke shear na-abawanye. Nke a nwere ike ịba uru maka nhazi, ebe ọ na-enye ohere ka slurry na-agba ọsọ ngwa ngwa n'oge nkedo, ịkpụzi, ma ọ bụ mkpuchi. A pụkwara imetụta omume rheological nke slurry site na ntinye uche, ịdị arọ molekụla, na ogo nke nnọchi nke CMC.

Nkwụsi ike

CMC nwere ike melite nkwụsi ike nke seramiiki slurry site na igbochi nhazi ma ọ bụ nkewa nke ụmụ irighiri ihe. Mgbakwunye nke CMC nwere ike ịmepụta nkwusioru kwụsiri ike site n'ịbawanye viscosity nke slurry, na-eme ka ikike ya jide ihe ndị ahụ na nkwusioru. Nke a dị mkpa karịsịa maka ngwa ebe ọ dị mkpa ka echekwa ma ọ bụ bufee slurry n'ebe dị anya, n'ihi na nhazi ma ọ bụ nkewa nwere ike ịkpata mkpuchi na-adịghị ahụkebe ma ọ bụ ịgba egbe na-ekwekọghị ekwekọ.

Ndakọrịta

Ndakọrịta nke CMC na akụkụ ndị ọzọ nke seramiiki slurry bụkwa ihe dị mkpa. CMC nwere ike iji ihe ndị ọzọ na-emekọrịta ihe, dị ka ụrọ, feldspars, na ihe ndị ọzọ, na-emetụta ihe onwunwe na arụmọrụ ha. Dịka ọmụmaatụ, mgbakwunye nke CMC nwere ike imeziwanye ihe ejikọtara ọnụ nke ụrọ, na-eme ka ahụ seramiiki siri ike ma na-adịgide adịgide. Agbanyeghị, oke CMC nwere ike bute oke oke oke, na-ebute ihe isi ike na nhazi na itinye n'ọrụ.

Usoro onunu ogwu

Usoro onunu ogwu nke CMC na seramiiki slurry bụ ihe dị mkpa ị ga-atụle. Usoro kachasị mma nke CMC ga-adabere na ngwa a kapịrị ọnụ, yana njirimara nke slurry na arụmọrụ achọrọ. N'ozuzu, ntinye nke CMC na ceramic slurry nwere ike ịdị site na 0.1% ruo 1%, dabere na ngwa ahụ. Ọnụ ọgụgụ dị elu nke CMC nwere ike ime ka slurry dị arọ ma kwụsie ike, ma ọ pụkwara iduga n'ịhazi na ngwa ngwa.

Mmechi

Na nchịkọta, CMC nwere ike imetụta njirimara nke seramiiki slurry, gụnyere viscosity ya, omume rheological, nkwụsi ike, ndakọrịta, na usoro onunu ogwu. Site n'ịghọta mmetụta CMC na akụrụngwa ndị a, ọ ga-ekwe omume ịkwalite arụmọrụ nke ceramic slurry maka ngwa dị iche iche, dị ka nkedo, ịkpụzi, mkpuchi, ma ọ bụ mbipụta. Iji CMC na seramiiki slurry formulations nwere ike ime ka nhazi, arụmọrụ, na ịdịte aka nke ngwaahịa seramiiki ka mma.
