He tairongo te Hydroxypropyl Methylcellulose (HPMC) ki te pH?
Te Waikawa Waikawa Metilururo (HPMC) he āhua rite kāore e pāngia e te pH ngā panonitanga, e hanga ana hei tāpiringa maha-whakamahinga i roto i ngā momo whakatakotoranga puta noa i te whānuitanga o te pH. Anei te taunekeneke a te HPMC me te pH:
- Te pumau i roto i ngā taumata pH rerekē
Ka taea e te HPMC te pupuri i tana mahi i roto i ngā taiao waikawa me te kawakore, ā, he pai te mahi i roto i te nuinga o te wā. te awhe pH o te 3 ki te 11He pai tēnei pumau mō tōna whakamahinga i roto i ngā ahumahi pēnei i te hanga whare, ngā rongoā, me te tiaki whaiaro, ina rerekē te pH o ngā hanganga.
- pH kūpapa (6-8): HPMC he tino pai te mahi i roto i tēnei awhe, ā, he pai mō te nuinga o ngā mahi whakapaipai me te kai.
- Ngā Āhuatanga Waikawa, Kawakore rāneiAhakoa e whai hua tonu ana i roto i ngā āhuatanga pH tino kino (i raro i te 3, i runga ake rānei i te 11), tera pea ka paku rerekē te wairewa me te matotoru, ahakoa e mau tonu ana ōna āhuatanga matotoru, pumau, me te here.
- Pānga ki te Matatini
- pH itiI ngā taiao tino waikawa (pH
- pH teiteiWaihoki, i ngā taumata pH teitei ake (pH > 11), ka taea te hekenga paku o te matotoru. Heoi anō, HPMC i te nuinga o te wā ka mau tonu te pumau o te hanganga, ā, ka mahi tonu i ana mahi e tika ana.
- Ngā tono i roto i ngā hua pH-tairongo
Nā te whānui o tōna ātete ki te pH, he pai te HPMC mō te whakamahi i roto i ngā hua he nui ngā rerekētanga pH:
- HangangaI roto i ngā hanganga e ahu mai ana i te moata me te sima, he maha ngā wā he pH kawakore, HPMC e pumau tonu ana, e whai hua ana hoki.
- Ngā rongoāHe mea whakamahi pinepine i roto i ngā whakatakotoranga rongoā ka rerekē pea te pH me te kore e ngaro tōna āhuatanga tukunga whakahaere, tōna āhuatanga matotoru rānei.
- Ngā mea whakapaipaiE whakamahia whānuitia ana te HPMC i roto i ngā hua pēnei i ngā hinu kiri, ngā kirimi, me ngā hopi horoi makawe, he rerekē ngā taumata pH i runga i te hanganga.
Whakamutunga
I a HPMC He ngawari te aro ki ngā taumata pH tino kino, ā, ka noho pumau tonu tōna mahi whānui puta noa i te whānuitanga o te pH. Nā tēnei pumau ka waiho hei wāhanga nui i roto i ngā hua ka taea e te pH te huri, kia mau tonu ai te mahi.
