1. 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.
2. 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 (ko te hua a tā mātou kamupene he 65 nekehanga Celsius), ka puta mārire te matotoru kia hanga he kōroiti matotoru mārama. Ka taea anake te whakamahi i te momo rewa wera ki 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.
3. 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 tere i te wā e whakamatao ana. E rua ngā tikanga noa e whakaahuatia ana penei:
1) 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 ki runga i te mata o te wai, kātahi ka hanga mārire hei paraoa pokepoke, ka whakamataohia i te wā e whakaoho ana.
2), 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 whakaemi, 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 whakamahi ngā kaihanga paura me te moata i tēnei tikanga. [Ka whakamahia te Hydroxypropyl methylcellulose (HPMC) hei whakamātotoru me te pupuri wai i roto i te moata paura moata. ]
4. Me pēhea te aromatawai i te kounga o te hydroxypropyl methylcellulose (HPMC) i roto i te huarahi māmā me te mārama?
Whakautu: (1) Mā: Ahakoa kāore e taea e te mā te whakatau mēnā he ngāwari te whakamahi i te HPMC, ā, mēnā ka tāpirihia he kaimā i te wā o te tukanga whakaputa, ka pā ki tōna kounga. Heoi, he pai te mā o te nuinga o ngā hua pai. (2) Maeneene: Ko te maeneene o te HPMC he 80 mata me te 100 mata, ā, he iti iho te 120 mata. Ko te nuinga o ngā HPMC e hangaia ana i Hebei he 80 mata. Ko te maeneene o te maeneene, ko te pai ake. (3) Te whakawhiti mārama: tāpirihia te hydroxypropyl methylcellulose (HPMC) ki roto i te wai hei hanga i tētahi colloid mārama, ā, tirohia tōna whakawhiti mārama. Ko te nui ake o te whakawhiti mārama, ko te pai ake, e tohu ana he iti ake ngā mea kore e rewa i roto. . He pai te urunga o ngā tauhohenga poutū, ā, he kino ake te urunga o ngā tauhohenga whakapae, engari ehara i te mea he pai ake te kounga o ngā tauhohenga poutū i te kounga o ngā tauhohenga whakapae, ā, he maha ngā āhuatanga e whakatau ana i te kounga o te hua. (4) Te taumaha motuhake: Ko te nui ake o te taumaha motuhake, ko te taumaha te pai ake. He nui te motuhaketanga, nā te mea he nui te ihirangi o te rōpū hydroxypropyl i roto, ā, he nui te ihirangi o te rōpū hydroxypropyl, he pai ake te pupuri wai.

9. 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 Ca(OH)2, CaO me te iti o 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.
10. He etera cellulose kore-ionic te HPMC, nō reira he aha te kore-ionic?
Whakautu: I te nuinga o te wā, ko te kore-katote he matū e kore e ionize i roto i te wai. Ko te ionization e pā ana ki te tukanga e wehea ai te electrolyte ki ngā ion charged 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 ionize hei whakaputa i ngā ion konutai neke noa (Na+) he charged pai me ngā ion pūhaumāota (Cl) he charged kino. Arā, ina whakanohoia te HPMC ki roto i te wai, e kore e wehea ki ngā ion charged, engari kei roto i te āhua o ngā ngota.
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, ko te iti o te nui o te methoxy ↓, ko te teitei ake o te pāmahana tiēre ↑.
12. 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. Mō ngā take motuhake, tirohia te pātai 9.
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.
14. He aha te kakara o te hydroxypropyl methylcellulose (HPMC)?
Whakautu: Ko te HPMC i hangaia mā te tikanga whakarewa e whakamahi ana i te toluene me te isopropanol hei whakarewa. Mēnā kāore i te tino pai te horoinga, ka toe mai he haunga.
15. 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.
