HPMC matotoru iti: Ko te HPMC 400 e whakamahia ana mō te moata whakataurite-ake, engari he mea kawemai i te nuinga o te wā.
Take: He iti te matotoru, ahakoa he ngoikore te pupuri wai, engari he pai te whakataurite, ā, he teitei te matotoru o te moata.
Te matotoru waenga me te matotoru iti:hydroxypropyl methylcelluloseKo te HPMC 20000-40000 te nuinga e whakamahia ana mō te whakapiri taera, te mea whakapiri, te moata ārai-pakaru, te moata here whakamahana, me ētahi atu.
Take: he pai te mahi, he iti ake te wai e tāpirihia ana, he kiato te moata.
1. He aha te kaupapa matua o te hydroxypropyl methylcellulose (HPMC)?
——A: 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: te taumata hanga, te taumata kai me te taumata rongoā i runga i te kaupapa. I tēnei wā, ko te nuinga o ngā hua o te whare he taumata hanga. I roto i te taumata hanga, he tino nui te nui 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 te rerekētanga o ā rātou whakamahinga?
——Whakautu: Ka taea te wehewehe i te HPMC ki te momo inamata me te momo rewa-wera. Ka tere te marara o ngā hua momo inamata ki te wai matao, ka ngaro ki roto i te wai. I tēnei wā, kāore he matotoru o te wai, nā te mea ka marara noa te HPMC ki te wai, ā, kāore he memeha tūturu. I muri i te 2 meneti pea, 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 taea te marara tere ki te wai wera, ka ngaro ki 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 roto i te paura putty me te moata. I roto i te kāpia wai me te peita, ka puta te āhuatanga piri, 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.
3. He aha ngā tikanga whakarewa o te hydroxypropyl methylcellulose (HPMC)?
——Whakautu: Tikanga whakarewa wai wera: Nā te mea kāore te HPMC e whakarewahia ki te wai wera, ka taea te whakamarara ōrite i te HPMC ki te wai wera i te tīmatanga, kātahi ka whakarewahia wawe ina whakamatao. E rua ngā tikanga noa e whakaahuatia ana penei:
1) Tāpirihia 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 mā te whakaoho.
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, kia rite ki te tikanga o te 1), whakamararatia te HPMC, whakaritea he parai wai wera; kātahi ka tāpirihia te toenga o te wai matao ki te wai wera. I roto i te parai, i 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 piri tahi, nā te mea he iti noa te HPMC i roto i ia kokonga iti. Ka memeha tonu te paura ina pā ki te wai. ——E whakamahia ana 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. ]
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 mea whakamārama ki 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 i hangaia i Hebei he 80 mata. Ko te maeneene o te maeneene, ko te pai ake. (3) Tukunga: Tāpirihia te hydroxypropyl methylcellulose (HPMC) ki roto i te wai hei hanga i tētahi colloid mārama, ā, tirohia tōna tukunga. Ko te teitei ake o te tukunga, ko te pai ake, e tohu ana he iti ake ngā matū kore e rewa i roto. Ko te urunga o te tauhohenga poutū he pai te nuinga, ā, he kino ake te tauhohenga whakapae, engari kāore e taea te kī he pai ake te kounga o te tauhohenga poutū i te tauhohenga whakapae, ā, he maha ngā āhuatanga e whakatau ana i te kounga o te hua. (4) Taumaha motuhake: ko te nui ake o te taumaha motuhake, ko te taumaha ake, ko te pai ake. He nui te taumaha motuhake, nā te mea he nui te ihirangi hydroxypropyl i roto, ā, he nui te ihirangi hydroxypropyl, he pai ake te pupuri wai.
5. Te nui o te hydroxypropyl methylcellulose (HPMC) i roto i te paura putty?
——Whakautu: Ka rerekē te nui o te HPMC e whakamahia ana i roto i ngā mahi whaihua i runga i te āhuarangi, te pāmahana, te kounga o te konupūmā pungarehu o te rohe, te tauira o te paura putty me te "kounga e hiahiatia ana e ngā kiritaki". I te nuinga o te wā, kei waenganui i te 4 kg me te 5 kg. Hei tauira, ko te nuinga o te paura putty i Beijing he 5 kg; ko te nuinga o te paura putty i Guizhou he 5 kg i te raumati me te 4.5 kg i te takurua;
6. He aha te matotoru tika o te hydroxypropyl methylcellulose (HPMC)?
——Whakautu: Ko te utu mō te paura putty he 100,000 yuan te nuinga, ā, he nui ake te tono mō te moata, ā, he ngāwari te whakamahi i te 150,000 yuan. Heoi anō, ko te mahi nui a te HPMC ko te pupuri i te wai, ā, muri iho ko te whakamātotoru. Mō te paura putty, mena he pai te pupuri i te wai, ā, he iti iho te matotoru (70,000-80,000), ka taea anō hoki. He pono, he teitei ake te matotoru, ā, he pai ake te pupuri wai. Ina neke atu te matotoru i te 100,000, kāore i te nui te pānga o te matotoru ki te pupuri wai.
7. He aha ngā tohu hangarau matua o te hydroxypropyl methylcellulose (HPMC)?
——Whakautu: Ko te nui o te hauwaiporoporo me te matotoru, he nui te aro o ngā kaiwhakamahi ki ēnei tohu e rua. Ko te teitei ake o te nui o te hauwaiporoporo, ko te pai ake o te pupuri wai. Ko te matotoru teitei, ko te pupuri wai, he pai ake (kaua ko te tino), ā, ko te matotoru teitei, he pai ake te whakamahi i roto i te moata sima.
8. He aha ngā rauemi matua o te hydroxypropyl methylcellulose (HPMC)?
—— A: Ko ngā rauemi mata matua o te hydroxypropyl methylcellulose (HPMC): te miro kua parakoretia, te methyl chloride, te propylene oxide, ko ētahi atu rauemi mata ko te alkali maramara, te waikawa, te toluene, te isopropanol, me ētahi atu.
9. He aha te mahi matua a te HPMC i roto i te whakamahinga o te paura putty, ā, he matū kei roto?
——Whakautu: E toru ngā mahi a te HPMC, arā, te whakamātotoru, te pupuri wai, me te hanga i roto i te paura putty. Whakamātotoru: Ka taea te whakamātotoru i te cellulose kia iri, kia ōrite, kia ōrite te otinga, ā, kia ātete hoki ki te totohu. Pupuri wai: Kia mārō te paura putty, ā, kia āwhina i te tauhohenga o te pungarehu konupūmā i raro i te mahi a te wai. Hanganga: He pānga whakahinuhinu tō te cellulose, ka taea ai te pai o te mahi a te paura putty. Kāore te HPMC e whai wāhi ki tētahi tauhohenga matū, ā, he mahi āwhina noa iho. He tauhohenga matū te tāpiri wai ki te paura putty me te whakatakoto ki te pakitara. Nā te hanganga o ngā matū hou, tangohia te paura putty i runga i te pakitara mai i te pakitara, hurihia kia paura, ka whakamahia anō. Kāore e mahi, nā te mea kua hangaia ngā 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 Konupūmā pungarehu i roto i te wai me te hau. I raro i te mahi a te CO2, ka puta te konupūmā kāponāte, ko te HPMC ia ka pupuri i te wai anake, ā, ka āwhina i te tauhohenga pai ake o te konupūmā pungarehu, ā, kāore e whai wāhi ki tētahi tauhohenga.
10. Ko te HPMC he kore-ionic cellulose ether, nō reira he aha te kore-ionic?
- Whakautu: Ki te kīanga māmā noa, ko ngā 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 utu nekeneke noa i roto i tētahi whakarewa motuhake (pērā i te wai, te waipiro). Hei tauira, ko te konutai pūhaumāota (NaCl), te tote e kainga ana i ia rā, ka rewa ki te wai ka iona hei whakaputa i ngā iona konutai nekeneke noa (Na+) he utu pai me ngā iona pūhaumāota (Cl) he utu kino. Arā, ina whakanohoia te HPMC ki roto i te wai, kāore e wehea hei iona utu, engari kei roto i te āhua o ngā ngota.
