1. He aha te whakamahinga matua ohydroxypropyl methylcellulose (HPMC)?
E whakamahia whānuitia ana te Hydroxypropyl methylcellulose i roto i ngā rauemi hanga, ngā paninga, ngā kapia hangai, ngā uku, te rongoā, te kai, ngā kakahu, te ahuwhenua, ngā mea whakapaipai, te tupeka me ētahi atu ahumahi. Ka taea te wehewehe i te Hydroxypropyl methylcellulose ki ngā momo hanga, ngā momo kai me ngā momo rongoā e ai ki tōna whakamahinga. 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?
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 ina tūtaki ki 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 ki roto i te wai, kāore he whakarewa 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 tere te marara ki 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 ki 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)?
Tikanga whakarewa wai wera: Nā te mea kāore te HPMC e rewa i roto i te wai wera, ka taea te whakamarara ōrite i te HPMC ki roto i te wai wera i te tīmatanga, kātahi ka rewa wawe ina whakamatao. 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, kia rite ki te tikanga 1), whakamararatia te HPMC hei whakarite i te para wai wera; kātahi ka tāpirihia te toenga o te wai matao ki te para 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 whakamahia tēnei tikanga e ngā kaihanga paura me ngā 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?
(1) Te Mā: Ahakoa kāore e taea e te mā te whakatau mena he ngāwari te whakamahi i te HPMC, ā, ki te 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) Te Maeneene: Ko te maeneene o te HPMC he 80 mata me te 100 mata te tikanga, he iti iho te 120 mata, ā, ko te nuinga o ngā HPMC e hangaia ana i Hebei he 80 mata. Ko te maeneene o te maeneene, ko te pai ake i te nuinga o te wā.
(3) Te 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 te kore e wairewa 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) Taumaha motuhake: Ko te nui ake o te taumaha motuhake, ko te taumaha ake, ko te pai ake. He nui te motuhaketanga, i te nuinga o te wā 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.
5. He aha te nui o te hydroxypropyl methylcellulose (HPMC) i roto i te paura putty?
Ko te nui o te HPMC e whakamahia ana i roto i ngā mahi mahi ka rerekē 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, i waenga 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; he iti noa te nui o te paura putty i Yunnan, ko te nuinga he 3 kg ki te 4 kg, me ētahi atu.
6. He aha te matotoru tika o te hydroxypropyl methylcellulose (HPMC)?
Ko te paura putty he nui te utu mō te 100,000 yuan, ā, he nui ake ngā whakaritenga mō te moata, ā, e hiahiatia ana te 150,000 yuan mō te whakamahinga ngāwari. Heoi anō, ko te mahi nui rawa atu a te HPMC ko te pupuri i te wai, ā, muri iho ko te whakamātotoru. I roto i te paura putty, mena he pai te pupuri i te wai, ā, he iti te matotoru (70,000-80,000), ka taea hoki. Ko te tikanga, ko te teitei ake o te matotoru, ko te pai ake o te pupuri wai whanaunga. Ina neke atu te matotoru i te 100,000, ka pā te matotoru ki te pupuri wai. Kāore e nui rawa atu.
7. He aha ngā tohu hangarau matua o te hydroxypropyl methylcellulose (HPMC)?
Ko te nui o te hauwaiporoporo me te matotoru, he āwangawanga te nuinga o ngā kaiwhakamahi mō ēnei tohu e rua. Ko te hunga he nui te hauwaiporoporo he pai ake te pupuri wai. Ko te mea he nui te matotoru he pai ake te pupuri wai, he āhua noa (ehara i te tino), ā, ko te mea he nui te matotoru he pai ake te whakamahi i roto i te moata sima.
8. He aha ngā rauemi mata matua ohydroxypropyl methylcellulose (HPMC)?
Ko ngā rauemi mata matua o te hydroxypropyl methylcellulose (HPMC): te miro parakore, te methyl chloride, te propylene oxide, me ētahi atu rauemi mata, te konutai waikura, te waikawa, te toluene, te isopropanol, me ētahi atu.
9. He aha te mahi matua o te whakamahinga o te HPMC ki te paura putty, ā, ka puta mai i te taha matū?
I roto i te paura putty, e toru ngā mahi a te HPMC, arā, te whakamātotoru, te pupuri wai, me te hanga. Te 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. Te 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. Te 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 puta he matū hou. Ki te tangohia e koe te paura putty i te pakitara mai i te pakitara, ka hurihia hei paura, ka whakamahia anō, kāore e mahi nā te mea kua puta he matū hou (konupūmā kāponāte). Ko ngā wāhanga matua o te paura konupūmā pungarehu ko: he ranunga o te Ca (OH)2, te 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.
10. He etera cellulose kore-ionic te HPMC, nō reira he aha te kore-ionic?
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, inaHPMCki te whakanohoia ki roto i te wai, e kore e wehea hei ngā katote kua utua, engari ka noho hei ngota ngota.
