Te konutai carboxymethyl cellulose (CMC)He mea nui te CMC hei etera cellulose wairewa-wai, he matū polymer anionic i whiwhihia mā te alkaliization me te etherification o te cellulose. Hei whakamātotoru, hei whakaū, hei emulsifier, hei hanga kiriata me te whakamakuku me te mahi tino pai, he whānuitia ngā tono nui a te CMC i roto i te umanga paraihe niho.
1. Te tūranga matua o te CMC i roto i te paraihe niho
1.1. Pānga whakamātotoru
Ko te mahi nui a te CMC he whakamātotoru. Ko ngā whakaritenga matua o te paraihe niho ko te pai o te matotoru o te whakapiri, te rere me te thixotropy e tika ana, te ngāwari ki te pēhi i waho o te ngongo paraihe niho, me te pupuri i te hanganga o te whakapiri i te wā e paraihe ana, ā, kaua e ngawari ki te ngaro. Ka taea e te CMC te hanga i tētahi otinga colloidal mārama ina rewa ki te wai, ka taea ai te whakanui ake i te matotoru o te pūnaha paraihe niho, ā, ka pai ake te matotoru me te pumau o te whakapiri.
1.2. Whakapūmautia te hanganga o te whakapiri
He pūnaha whakakotahi te parai niho i hangaia mai i ngā wāhanga maha (pērā i ngā mea whakakoi, ngā mea horoi, ngā mea kakara, te glycerin, te wai, me ētahi atu). Ka taea e te CMC te whai wāhi pai ki te whakatārewatanga me te whakau, ka tohatoha ōrite ngā matūriki totoka (pērā i ngā mea whakakoi) i roto i te anga, ka ārai i te paparanga, te whakatō me te wehenga wai, ā, ka roa ake te ora o te hua.
1.3. Whakapai ake i te pā me te horapa
He māeneene, he ngawari hoki te otinga CMC, ka taea ai te whakapai ake i te reka o te paraihe niho, kia māeneene ake ai ina whakamahia, me te kore e whakapataritari i ngā kapia, ā, ka pai ake ai te wheako kaiwhakamahi. I taua wā anō, he āhuatanga hanga kiriata tō te CMC, e āwhina ana ki te hanga i tētahi kiriata tiaki, ā, he pānga tiaki ngawari ki te kiriuhi waha.
1.4. Te tukunga whakahaere me te pānga whakamakuku
Ka tāpirihia ngā kai hohe (pēnei i te fluoride, ngā āhuatanga ārai-mate pāwera, me ētahi atu) ki ētahi paraihe niho mahi. Ka taea e te CMC te āwhina ki te whakahaere i tō rātou tere tuku me te whakapai ake i te whai huatanga o te whakamahinga o ngā kai hohe. Hei tāpiri, he kaha te kaha o te CMC ki te mimiti i te makuku me te whakamakuku, ka āwhina i te aukati i te maroke me te pakaru o te paraihe niho, ā, ka whakapai ake i te pumau o te rokiroki.
2. Ngā painga mahi a te CMC
2.1. Te wairewatanga nui me te haumaru
Ka taea te whakarewa tere i te CMC ki te wai matao, he ngāwari ki te whakamahi, kāore e hiahiatia he whakamahana, ā, e tutuki ana i ngā whakaritenga hanga tere o te umanga paraihe niho. He hua pūmua tūturu kua whakarerekētia te CMC, he pai te hototahi ki te koiora me te haumaru ā-waha. Kāore he paitini, kāore hoki e whakapataritari, ā, kāore e pā kino ki te hauora o te tangata.
2.2. Te kaha ki te whakarerekē i te matotoru
He whānuitia ngā taumata matotoru o ngā hua CMC (i waenga i te 25 ki te 8000mPa·s te nuinga), ka taea te whiriwhiri i runga i ngā hiahia motuhake o ngā tauira paraihe niho, kia taea ai te hoahoa whaiaro i te kakano whakapiri.
2.3. Hototahi pai
He pai te hototahitanga o te CMC me ētahi atu wāhanga e whakamahia whānuitia ana o te paraihe niho (pērā i te glycerin, te sorbitol, te kaihoko pahuka, te mea whakakoi, me ētahi atu), ā, he pumau te mahi i roto i ngā pūnaha rerekē.
3. Ngā whakatūpato mō te whakamahi i te CMC
Me mārama ki ngā āhuatanga e whai ake nei i te wā e whakamahia ana te CMC i roto i te ranunga paraihe niho:
Whakahaerehia te nui o te tāpiri: Ko te nui o te tāpiri whānui he 0.5% ki te 1.5%, i runga i ngā whakaritenga mō te matotoru o te hua. Mā te whakamahi nui rawa ka matotoru rawa te whakapiri, ā, ka uaua ki te whakaputa.
Tikanga whakarewa tika: Me ata tāpiri ki te wai i raro i ngā tikanga whakaoho kia kore ai e puta he puranga. Ka taea hoki te whakaranu ki ngā mea whakamakuku pēnei i te glycerin i mua i te wā, kātahi ka tāpirihia ki te wai kia whakarewahia kia pai ake ai te whai huatanga o te horapa.
Tirotiro hototahi tātai: Tērā pea ka pāngia e ngā tauhohenga kino ki ētahi matū horoi cationic, ki ētahi tote inorganic kukū-teitei rānei, ā, me whakahaere he whakamātautau iti hei manatoko i tōna hototahi.
4. Te whanaketanga o te CMC i roto i te umanga paraihe niho
I te aro nui o te tangata ki te hauora o te waha me te whanaketanga kanorau o te paraihe niho mahi, kua piki ake ngā whakaritenga mō te mahi a ngā rauemi mata paraihe niho. Hei whakamātotoru tuku iho, kua pakari hoki, kei te pumau tonu te tūranga o te CMC. Heoi, kia tutuki ai ngā whakaritenga tukanga me te reka uaua ake, kei te whakawhanake hoki te umanga i ngā pūnaha CMC whakarerekētia (pēnei i te hononga whakawhiti, te esterified, me ētahi atu) me ngā pūnaha matū (pēnei i te CMC me te xanthan gum, te guar gum, me ētahi atu) hei whakapai ake i te mahi whakapiri. Hei tāpiri, ko te pikinga ake o ngā rauemi mata matomato, taiao me te hoa taiao kua akiaki i te CMC ki te whanake i te huarahi ki te parakore teitei, te iti o te poke me te iti o te ether toenga.
Hei wāhanga matua mō te whakamātotoru me te whakau i roto itātai paraihe niho te konutai carboxymethyl cellulose (CMC)Kua whānuitia te whakamahinga o te CMC i roto i te hanga paraihe niho puta noa i te ao nā te mea he tino pai ōna āhuatanga ā-tinana, ā-matū hoki, tōna haumaru me tōna ōhanga. Ā tōna wā, me te whanaketanga o te hangarau hanga CMC me te whakapai tonu i ngā hua paraihe niho, ka nui ake te mahi a te CMC ki te whakapai ake i te kounga o te paraihe niho me te wheako o te kaiwhakamahi.
