Te konutai carboxymethyl cellulose (CMC)He matū carboxymethylated te matū nei nō te cellulose, e mōhiotia ana ko te kapia cellulose, ā, koia te kapia cellulose ionic tino nui. Ko te CMC he matū polymer anionic i whiwhihia mā te tauhohenga i te cellulose tūturu me te kawakore caustic me te waikawa monochloroacetic. Ko te taumaha ngota o te matū kei waenga i ngā tekau miriona ki ngā miriona.
【Ngā Āhuatanga】Paura mā, kāore he kakara, ka wairewa ki te wai hei hanga i tētahi otinga matotoru, kāore e wairewa ki te etanoru me ētahi atu whakarewa.
【Whakamahinga】He mahi whakatārewatanga me te whakaemulsification, he pai te piripono me te ātete tote, ā, e mōhiotia ana ko te "monosodium glutamate ahumahi", e whakamahia whānuitia ana.
Te whakarite i te CMC
E ai ki te momo etherification rerekē, ka taea te wehewehe i te hanga CMC ā-ahumahi kia rua ngā wāhanga: te tikanga wai-e hangai ana ki te wai me te tikanga whakarewa-e hangai ana ki te wai. Ko te tikanga whakamahi wai hei reo tauhohenga ka kiia ko te tikanga wai-e hangai ana ki te wai, e whakamahia ana hei hanga reo kawakore me te CMC iti-kounga; ko te tikanga whakamahi whakarewa waro hei reo tauhohenga ka kiia ko te tikanga whakarewa, e tika ana mō te hanga CMC reo-kounga me te CMC teitei-kounga. Ka mahia ēnei tauhohenga e rua i roto i te mīhini pokepoke, e pā ana ki te tukanga pokepoke, ā, koinei te tikanga matua mō te hanga CMC i tēnei wā.

tikanga wai
Ko te tikanga wai-whakapūmau he tukanga whakaputa ahumahi o mua, arā, ko te tauhohe i te cellulose alkali me te kaihoko etherifying i roto i te āhua o te alkali me te wai kore utu. I te wā o te tukanga alkaliization me te etherification, kāore he reo rauropi i roto i te pūnaha. He māmā noa ngā whakaritenga taputapu o te tikanga wai-whakapūmau, he iti ake te haumi me te iti o te utu. Ko te ngoikoretanga ko te kore o te nui o te reo wai, ā, ko te wera e puta mai ana i te tauhohenga ka whakanui ake i te pāmahana, ka tere ake te tere o ngā tauhohenga taha, ka hua ake he iti te whai huatanga o te etherification me te kounga hua ngoikore. Ka whakamahia tēnei tikanga hei whakarite i ngā hua CMC waenga me te iti, pērā i ngā hopi horoi, ngā kaihoko rahi kakahu, me ētahi atu.

tikanga whakarewa
E mōhiotia ana hoki te tikanga whakarewa ko te tikanga whakarewa waro. Ko tōna āhuatanga matua ko te whakahaere i ngā tauhohenga alkaliization me te etherification i raro i te tikanga me whakamahi te whakarewa waro hei reo tauhohenga (diluent). E ai ki te nui o te waiwhakarewa tauhohenga, ka wehea ki te tikanga pokepoke me te tikanga para. He rite tonu te tikanga whakarewa ki te tukanga tauhohenga o te tikanga wai-hāngai, ā, e rua ngā wāhanga o te alkaliization me te etherification, engari he rerekē te reo tauhohenga o ēnei wāhanga e rua. Ka whakakorehia e te tikanga whakarewa ngā tukanga kei roto i te tikanga wai-hāngai, pērā i te rumaki, te pēhi, te kuru, te pakeke, me ētahi atu, ā, ka mahia te alkaliization me te etherification i roto i te mīhini pokepoke. Ko te ngoikoretanga he iti te kaha ki te whakahaere i te pāmahana, he nui te wāhi me te utu. Ko te tikanga, mō te hanga i ngā whakatakotoranga taputapu rerekē, me tino whakahaere te pāmahana pūnaha, te wā whāngai, me ētahi atu, kia taea ai te whakarite i ngā hua he kounga pai me te mahi pai. Kei te whakaatuhia tana tūtohi rere tukanga i te Pikitia 2.

Te Tūnga o te Whakaritenga o te KonutaiCarboxymethyl Cellulosemai i ngā Hua-taha Ahuwhenua
He rerekē ngā momo hua o te hua, he ngāwari hoki te tiki atu, ā, ka taea te whakamahi whānui hei rauemi mata mō te hanga CMC. I tēnei wā, ko te nuinga o ngā rauemi mata o te hanga CMC he cellulose kua parakore, tae atu ki te muka miro, te muka manioka, te muka kakau witi, te muka pāpaka, te muka kakau witi, me ētahi atu. Heoi, me te whakatairanga tonu i ngā tono CMC i ngā āhuatanga katoa o te ao, i raro i ngā rauemi tukatuka rauemi mata o nāianei, ko te whakamahi i ngā puna rauemi mata iti ake te utu me te whānui ake mō te hanga CMC ka tino arotahihia.
Tirohanga
Ka taea te whakamahi i te konutai carboxymethyl cellulose hei emulsifier, hei flocculant, hei thickener, hei chelating agent, hei pupuri wai, hei piripiri, hei rahi, hei rauemi hanga kiriata, me ētahi atu. He whānuitia te whakamahinga i roto i ngā mahi hiko, hiako, kirihou, tānga, uku, te whakamahinga o ia rā, matū me ētahi atu mara, ā, nā tōna mahi pai me te whānuitanga o ngā whakamahinga, kei te whakawhanake tonu i ngā mara tono hou. I ēnei rā, i raro i te horapa whānui o te ariā o te hanga matū matomato, kei te rangahauhia e ngā rangahau o tāwāhi mō...CMCKo te hangarau whakarite e arotahi ana ki te rapu rauemi mata koiora iti te utu, ngāwari hoki te tiki, me ngā tikanga hou mō te purenga CMC. Hei whenua whai rauemi ahuwhenua nui, kei roto tōku whenua i te whakarerekētanga cellulose. Mō te hangarau, he painga ōna rauemi mata, engari he raruraru anō hoki pērā i te koretake o te tukanga whakarite nā ngā momo pūtake muka cellulose koiora me ngā rerekētanga nui o ngā wāhanga. Kei te mau tonu ngā ngoikoretanga o te rawaka o te whakamahinga o ngā rauemi koiora, nō reira me whakahaere he rangahau whānui mō ngā whakatutukitanga i roto i ēnei wāhanga.
