1. He aha te ingoa kē o te hydroxypropyl methylcellulose?
——Whakautu: Hydroxypropyl Methyl Cellulose, Ingarihi: Hydroxypropyl Methyl Cellulose Whakarāpopototanga: HPMC, MHPC rānei Ingoa Ingoa: Hypromellose; Cellulose Hydroxypropyl Methyl Ether; Hypromellose, Cellulose, 2-hydroxypropylmethyl Cellulose ether. Cellulose hydroxypropyl methyl ether Hyprolose.
2. He aha te whakamahinga matua o te hydroxypropyl methylcellulose (HPMC)?
——Whakautu: He whānuitia te whakamahinga o te HPMC i roto i ngā rauemi hanga, ngā paninga, ngā kapia hangai, ngā uku, ngā rongoā, ngā kai, ngā kakahu, ngā ahuwhenua, ngā mea whakapaipai, ngā tupeka me ētahi atu ahumahi. Ka taea te wehewehe i te HPMC ki ngā momo hanga, ngā momo kai me ngā momo rongoā i runga i te kaupapa. I tēnei wā, ko te nuinga o ngā hua o te whare he momo hanga. I roto i te momo hanga, he nui te whakamahinga o te paura putty, tata ki te 90% e whakamahia ana mō te paura putty, ā, ko te toenga e whakamahia ana mō te moata sima me te kāpia.
3. He maha ngā momo hydroxypropyl methylcellulose (HPMC), ā, he aha ngā rerekētanga o ā rātou whakamahinga?
——Whakautu: Ka taea te wehewehe i te HPMC ki te momo tere tonu me te momo whakarewa wera. Ka tere te marara o ngā hua momo tere tonu i roto i te wai matao ka ngaro atu ki roto i te wai. I tēnei wā, kāore he matotoru o te wai nā te mea ka marara noa te HPMC i roto i te wai me te kore e whakarewa tūturu. Tata ki te 2 meneti, ka piki haere te matotoru o te wai, ka hanga he kōroiti matotoru mārama. Ko ngā hua rewa wera, ina tūtaki ki te wai matao, ka tere te marara i roto i te wai wera ka ngaro atu i roto i te wai wera. Ina heke te pāmahana ki tētahi pāmahana, ka puta mārire te matotoru kia hanga he kōroiti matotoru mārama. Ka taea anake te whakamahi i te momo rewa wera ki roto i te paura putty me te moata. I roto i te kāpia wai me te peita, ka puta he āhuatanga rōpū, ā, kāore e taea te whakamahi. He whānui ake ngā tono o te momo tere tonu. Ka taea te whakamahi i roto i te paura putty me te moata, tae atu ki te kāpia wai me te peita, me te kore he ārai.
4. Me pēhea te whiriwhiri i tētahi hydroxypropyl methylcellulose (HPMC) e tika ana mō ngā kaupapa rerekē?
——Whakautu::Te tono paura putty: He iti noa ngā whakaritenga, ā, ko te matotoru he 100,000, he nui tēnā. Ko te mea nui kia pai te pupuri i te wai. Te tono moata: he nui ake ngā whakaritenga, he matotoru teitei, he pai ake te 150,000. Te tono kāpia: me whai hua tere me te matotoru teitei.
5. He aha ngā mea hei aro atu ki te whakamahinga tūturu o te whanaungatanga i waenga i te matotoru me te pāmahana o te HPMC?
——Whakautu: He rite whakamuri te matotoru o te HPMC ki te pāmahana, arā, ka piki ake te matotoru i te hekenga o te pāmahana. Ko te matotoru o tētahi hua e kōrerohia ana e tātou e pā ana ki te hua whakamātautau o tōna wairewa 2% i te pāmahana o te 20 nekehanga Celsius.
I roto i ngā mahi whaihua, me mōhio kei ngā wāhi he nui ngā rerekētanga pāmahana i waenga i te raumati me te takurua, me whakamahi i te matotoru iti i te takurua, he pai ake mō te hanga. Ki te kore, ina iti te pāmahana, ka piki ake te matotoru o te cellulose, ā, ka taumaha te pa o te ringa i te wā e waruhia ana.
Matotoru waenga: 75000-100000 e whakamahia ana mō te putty
Take: he pai te pupuri wai
Te matotoru teitei: 150000-200000. E whakamahia ana mō te moata whakamahana matūriki polystyrene, te paura rapa, me te moata whakamahana wera o ngā miro moroiti kua whakakikoruatia.
Take: He teitei te matotoru, kāore te moata e ngawari ki te taka, ki te piko, ā, kua pai ake te hanganga.
6. He etera cellulose kore-ionic te HPMC, nō reira he aha te kore-ionic?
——Whakautu: Ki te kīanga māmā noa, ko ngā mea kore-iona he matū kāore e iona i roto i te wai. Ko te iona e pā ana ki te tukanga e wehea ai te electrolyte ki ngā iona kua utua ka taea te neke noa i roto i tētahi whakarewa motuhake (pēnei i te wai, te waipiro). Hei tauira, ko te konutai pūhaumāota (NaCl), te tote e kainga ana e tātou i ia rā, ka rewa ki te wai ka iona hei whakaputa i ngā iona konutai (Na+) neke noa he utu pai me ngā iona pūhaumāota (Cl) he utu kino. Arā, ina whakanohoia te HPMC ki roto i te wai, e kore e wehea hei iona kua utua, engari kei roto i te āhua o ngā ngota.
