1. He aha ngā tikanga whakarewa o te hydroxypropyl methylcellulose HPMC?
Whakautu: Tikanga whakarewa wai wera: Nā te mea kāore te HPMC e whakarewa i te wai wera, ka taea te horapa ōrite te HPMC ki te wai wera i te tīmatanga, kātahi ka whakarewa wawe ina whakamatao. E rua ngā tikanga noa e whakaahuatia ana penei:
1), tāpirihia te 1/3, te 2/3 rānei o te nui o te wai e hiahiatia ana ki roto i te ipu, ka whakamahana ki te 70°C, ka whakamararatia te HPMC kia rite ki te tikanga o te 1), ka whakarite i te parai wai wera; kātahi ka tāpirihia te toenga o te wai matao ki te parai wai wera, ka whakamataohia te ranunga i muri i te whakaoho.
Tikanga whakaranu paura: whakaranua te paura HPMC me te nui o ētahi atu matū paura, whakaranua kia pai ki te mīhini whakaranu, kātahi ka tāpirihia he wai kia memeha, kātahi ka taea te memeha te HPMC i tēnei wā me te kore e haaputuputu, nā te mea he iti noa te HPMC i roto i ia kokonga iti. Ka memeha tonu te paura ina pā ki te wai. ——Kei te whakamahia tēnei tikanga e ngā kaihanga paura me te moata. [Ka whakamahia te Hydroxypropyl methylcellulose (HPMC) hei whakamātotoru me te pupuri wai i roto i te moata paura moata.
2) Ringihia te nui o te wai wera e hiahiatia ana ki roto i te ipu, ka whakamahana kia 70°C pea. I tāpirihia mārire te hydroxypropyl methylcellulose me te whakaoho mārire, i te tīmatanga ka mānu te HPMC i runga i te mata o te wai, kātahi ka hanga mārire hei paraoa pokepoke, ka whakamataohia i te wā e whakaoho ana.
2. He maha ngā momo hydroxypropyl methylcellulose HPMC. He aha ngā rerekētanga o ā rātou whakamahinga?
Whakautu: Ka taea te wehewehe i te HPMC Hydroxypropyl methylcellulose ki te momo inamata me te momo whakarewa-wera. Ka tere te horapa o ngā hua momo inamata i roto i te wai matao ka ngaro ki roto i te wai. I tēnei wā, kāore he matotoru o te wai, nā te mea ka horapa noa te HPMC i roto i te wai, kāore he rewa tūturu. Tata ki te 2 meneti, ka piki haere te matotoru o te wai, ka hanga he koroka matotoru mārama. Ko ngā hua rewa-wera, ina tūtaki ki te wai matao, ka tere te horapa i roto i te wai wera ka ngaro i roto i te wai wera. Ina heke te pāmahana ki tētahi pāmahana, ka puta mārire te matotoru kia hanga he koroka matotoru mārama. Ka taea anake te whakamahi i te momo rewa-wera i 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 inamata. 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.

8. He aha te mahi matua o te whakamahinga o te HPMC ki te paura putty, ā, ka puta mai i te taha matū?
Whakautu: I roto i te paura putty, e toru ngā mahi a te HPMC, arā, te whakamātotoru, te pupuri wai, me te hanga. Whakamātotoru: Ka taea te whakamātotoru i te cellulose hei whakairi me te pupuri i te otinga kia ōrite ki runga, ki raro hoki, ā, kia ātete hoki ki te totohu. Pupuri wai: kia āta maroke te paura putty, ā, kia āwhina i te pungarehu o te konupūmā kia tauhohe i raro i te mahi a te wai. Hanganga: He pānga whakahinuhinu tō te cellulose, ka taea ai te hanga pai o te paura putty. Kāore te HPMC e whai wāhi ki tētahi tauhohenga matū, engari he mahi āwhina noa iho. He tauhohenga matū te tāpiri wai ki te paura putty me te whakatakoto ki te pakitara, nā te mea ka hangaia he matū hou. Ki te tangohia e koe te paura putty i runga i te pakitara mai i te pakitara, ka hurihia hei paura, ka whakamahia anō, kāore e mahi nā te mea kua hangaia he matū hou (konupūmā kāponāte). Ko ngā wāhanga matua o te paura konupūmā pungarehu ko: he ranunga o te Ca(OH)2, CaO me te iti o te CaCO3, CaO+H2O=Ca(OH)2—Ca(OH)2+CO2=CaCO3↓+H2O Kei roto i te wai me te hau te konupūmā pungarehu. I raro i te mahi a te CO2, ka puta te konupūmā kāponāte, ko te HPMC ia ka pupuri i te wai anake, ka āwhina i te tauhohenga pai ake o te konupūmā pungarehu, ā, kāore e whai wāhi ki tētahi tauhohenga.
9. He etera cellulose kore-ionic te HPMC, nō reira he aha te kore-ionic?
Whakautu: Ki te kīanga māmā noa, ko te kore-katote he matū e kore e ioni i roto i te wai. Ko te ioni 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 ioni 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.
10. He hononga kei waenganui i te maturuturunga iho o te paura putty me te HPMC?
Whakautu: Ko te ngaronga o te paura o te paura putty e pā ana ki te kounga o te konupūmā pungarehu, ā, he iti noa iho te pānga ki te HPMC. Ko te iti o te konupūmā o te konupūmā hina me te ōwehenga hē o te CaO me te Ca(OH)2 i roto i te konupūmā hina ka puta te ngaronga o te paura. Mena he pānga ki te HPMC, ki te kore e pai te pupuri wai o te HPMC, ka puta hoki te ngaronga o te paura.
11. He aha te pānga o te pāmahana tiēre o te hydroxypropyl methylcellulose?
Whakautu: E pā ana te pāmahana tiēre o te HPMC ki te nui o te methoxy, ka iti ake te nui o te methoxy↓, ka teitei ake te pāmahana tiēre.
12. Me pēhea te whiriwhiri i te hydroxypropyl methylcellulose (HPMC) e tika ana mō ngā kaupapa rerekē?
Whakautu: Te paninga o te paura putty: he iti noa ngā whakaritenga, ā, ko te matotoru he 100,000, he rawaka. Ko te mea nui kia pai te pupuri i te wai. Te paninga o te moata: he nui ake ngā whakaritenga, he matotoru teitei, he pai ake te 150,000. Te paninga o te kāpia: me whai hua tere me te matotoru teitei.
13. He aha te rerekētanga i waenga i te momo wai matao inamata me te momo hydroxypropyl methylcellulose wairewa-wera i roto i te tukanga whakaputa?
Whakautu: Ko te momo HPMC wai matao inamata ka rongoatia ki te glyoxal, ā, ka tere te horapa i roto i te wai matao, engari kāore e tino memeha. Ka memeha noa ina piki ake te matotoru. Kāore ngā momo rewa wera e rongoatia ki te glyoxal. Mena he nui te nui o te glyoxal, ka tere te horapa, engari ka puhoi te piki o te matotoru, ā, ki te iti te nui, ka rerekē te āhua.

Whakautu: Hydroxypropyl Methyl Cellulose, Ingarihi: Hydroxypropyl Methyl Cellulose Whakarāpopototanga: HPMC, MHPC rānei Ingoa Ingoa: Hypromellose; Cellulose hydroxypropyl methyl ether; Hypromellose, Cellulose, 2-hydroxypropyl methyl Cellulose ether. Cellulose hydroxypropyl methyl ether Hyprolose.
16. 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 Ka whakamahia whānuitia mō te putty. Take: he pai te pupuri wai. Matotoru teitei: 150000-200000 Ka whakamahia whānuitia mō te moata whakamahana matūriki polystyrene paura kāpia me te moata whakamahana moata moata moata moata moata. Take: he matotoru teitei, kāore e ngāwari te taka, te whakairi, me te whakapai ake i te hanganga.
17. He aha te take o ngā mirumiru i roto i te paura putty i te whakamahinga o te HPMC?
Whakautu: I roto i te paura putty, e toru ngā mahi a te HPMC, arā, te whakamātotoru, te pupuri wai me te hanga. Kaua e whai wāhi ki tētahi tauhohenga. Ngā take mō ngā mirumiru: 1. Ringihia he nui rawa te wai. 2. Kāore te paparanga o raro i te maroke, waruhia tētahi atu paparanga ki runga, ā, ka ngāwari te pahuka.
