1. Whakataki ki te Hydroxypropyl Methylcellulose (HPMC)
Te Waikawa Waikawa Metilururo (HPMC)He etera cellulose kore-ionic i hangaia mai i te muka miro maori, i te penupenu rakau rānei mā te whakarerekētanga matū. He pai te wairewatanga o te HPMC ki te wai, ki te matotoru, ki te pumau, ki ngā āhuatanga hanga kiriata me te hototahi ki te koiora, nō reira e whakamahia whānuitia ana i roto i te hanga, te rongoā, te kai, ngā matū o ia rā me ētahi atu mara.
2. Ngā taahiraa whakaputa o te HPMC
Ko te hanga o te HPMC ko ngā mahi matua e whai ake nei:
Te whakarite rauemi mata
Ko te rauemi mata matua o te HPMC he cellulose taiao tino parakore (he mea hanga mai i te miro, i te penupenu rakau rānei), e hiahia ana kia tukatukahia i mua hei tango i ngā poke me te whakarite i te parakore me te ōritetanga o te cellulose.
Te maimoatanga whakapūkara
Whakanohoia te cellulose ki roto i tētahi tauhohenga, ka tāpirihia he nui e tika ana o te wairewa konutai hauwai (NaOH) hei pupuhi i te cellulose i roto i te taiao kawakore hei hanga cellulose kawakore. Ka taea e tēnei tukanga te whakanui ake i te mahi a te cellulose me te whakarite mō ngā tauhohenga etherification e whai ake nei.
Tauhohenga whakapūmau
I runga i te cellulose alkali, ka whakaurua ngā kaihoko methylating (pērā i te methyl chloride) me ngā kaihoko hydroxypropylating (pērā i te propylene oxide) hei whakahaere i te tauhohenga etherification. Ko te tikanga ka mahia te tauhohenga i roto i tētahi tauhohenga pēhanga teitei kua kati. I tētahi pāmahana me te pēhanga, ka whakakapia ngā rōpū hydroxyl i runga i te cellulose e ngā rōpū methyl me te hydroxypropyl hei hanga i te hydroxypropyl methylcellulose.
Horoi whakakorekore
I muri i te tauhohenga, tera pea kei roto i te hua ngā matū me ngā hua taha kāore anō kia tauhohe, nō reira me tāpiri he otinga waikawa hei maimoatanga whakakore, kātahi ka horoia ki te nui o te wai, ki te whakarewa waro rānei hei tango i ngā matū me ngā poke kawakore e toe ana.
Te maroke me te whakamaroke
Ka hurihia te wai HPMC kua horoia, ka tātarihia rānei hei tango i te wai nui, kātahi ka whakamahia te hangarau whakamaroke pāmahana-iti hei hanga paura maroke, hei maramara rānei hei pupuri i ngā āhuatanga ā-tinana me te matū o te HPMC.
Te huri me te tātari
Ka tukuna te HPMC maroke ki te taputapu huri hei kuru kia puta ai he paura HPMC o ngā rahi matūriki rerekē. Whai muri i tēnā, ka tirotirohia me te whakarōpūtia kia rite ai te hua kia tutuki ai ngā whakaritenga tono rerekē.
Te tākai me te rokiroki
I muri i te tirotiro i te kounga, ka tākaihia te hua whakamutunga kia rite ki ngā whakamahinga rerekē (pēnei i te 25kg/pēke) ka rongoatia ki te taiao maroke, hauhautanga hoki hei ārai i te makuku, i te poke rānei.
3. Ngā wāhanga tono matua o te HPMC
Nā te pai o ōna āhuatanga whakamātotoru, hanga kiriata, pupuri wai, whakaemulsifying me te biocompatibility, kua whānuitia te whakamahinga o te HPMC i roto i ngā ahumahi maha:
