Te mahi me te whakarōpūtanga o te HPMC

He iti te matotoru: Ko te 400 te mea e whakamahia ana mō te moata whakataurite-ake, engari he mea kawemai i te nuinga o te wā.

Take: He iti te matotoru, he ngoikore te pupuri wai, engari he pai ngā āhuatanga whakataurite, he nui te kiato o te moata.

Te matotoru waenga me te matotoru iti: Ko te 20000-40000 te nuinga e whakamahia ana mō te piripiri taera, te mea whakapiri, te moata ārai-pakaru, te moata here whakamahana, me ētahi atu.

Ngā Take: He pai te mahi, he iti ake te wai e tāpirihia ana, ā, he nui te mātotoru o te moata.

1. He aha ngā whakamahinga 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 whakamahinga. I tēnei wā, ko te nuinga o ngā hua o te whare he taumata hanga. I roto i te taumata 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. E hia ngā momo hydroxypropyl methylcellulose (HPMC) kei reira? He aha ngā whakamahinga o aua momo?

——A: Ka taea te wehewehe i te HPMC ki te momo inamata me te momo rewa wera. Ka tere te marara o ngā hua inamata ki te wai matao, ka ngaro atu i te wai. Kāore he matotoru o te wai i tēnei wā nā te mea ka marara noa te HPMC ki te wai, kāore i te tino rewa. I muri i te 2 meneti pea, ka piki haere te matotoru o te wai, ā, ka puta he kōroiti matotoru mārama. Ka tere te marara o ngā hua wairewa-wera ki te wai wera, ka ngaro atu i te wai wera ina tūtaki ki te wai matao. Ina heke te pāmahana ki tētahi pāmahana (ko te hua a tā mātou kamupene he 65 nekehanga Celsius), ka puta mārire te matotoru kia puta rā anō he kōroiti matotoru mārama. Ka taea anake te whakamahi i te momo rewa wera mō te paura putty me te moata. I roto i te kāpia wai me te peita, ka puta te piri, ā, kāore e taea te whakamahi. He whānui ake ngā tono o te momo inamata. Ka taea te whakamahi mō te paura putty, te moata, 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 e wairewa te HPMC i roto i te wai wera, ka taea te horapa ōrite te HPMC ki roto i te wai wera i te tīmatanga, ā, ka tere te wairewa i muri i te whakamatao. E rua ngā tikanga noa e whakamāramahia ana i raro nei:

1) Ringihia te nui o te wai wera e hiahiatia ana ki roto i te ipu, ka whakamahana kia tata ki te 70℃. 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 paru, ā, ka whakamatao mārire i 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, whakamahanahia ki te 70°C, whakamararatia te HPMC kia rite ki te tikanga i te 1), ka whakarite i te para wai wera; kātahi ka tāpirihia te toenga o te wai matao ki te para wai wera. Ringihia te para ki roto i te wai, whakaohokia, ka whakamatao i te ranunga.

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. I tēnei wā, ka taea te memeha te HPMC, ā, e kore e piri tahi, nā te mea he iti noa te HPMC kei roto i ia wāhanga. He koki iti. Ka memeha tonu te paura ina pā ki te wai. ——Ka whakamahia tēnei tikanga e ngā kaihanga paura me ngā moata whakapūtā. Ka whakamahia te Hydroxypropyl methylcellulose (HPMC) hei whakamātotoru me te pupuri wai i roto i te moata paura whakapūtā.

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 te mā e whakatau mēnā he ngāwari te whakamahi i te HPMC, mēnā ka tāpirihia he rama 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) Mā: Ko te mā 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 mā, ko te mā, ko te pai ake. (3) Te tuku mārama: Tāpirihia te hydroxypropyl methylcellulose (HPMC) ki roto i te wai hei hanga i tētahi colloid mārama, ā, tirohia tōna tuku mārama. Ko te teitei ake o te tuku mārama, ko te pai ake, e tohu ana he iti ake ngā matū kore e rewa i roto. Ko te urunga hau o ngā tauhohenga poutū he pai ake i ngā tauhohenga whakapae, engari kāore e taea te kī he pai ake te kounga o ngā tauhohenga poutū i ngā tauhohenga whakapae. 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 me te taumaha, ko te pai ake. Ko te taumaha motuhake nā te nui o te hydroxypropyl i roto. Ka nui ake te hydroxypropyl i roto i te tinana, ka pai ake te pupuri wai.

5. He aha te horopeta o te hydroxypropyl methylcellulose (HPMC) i roto i te paura putty?

——Whakautu: Ka rerekē te horopeta o te HPMC i roto i ngā whakamahinga tūturu i runga i te āhuarangi, te pāmahana, te kounga o te konupūmā pungarehu ā-rohe, me te tātai whakauru. paura ty me te "kounga e hiahiatia ana e te kiritaki". I te nuinga o te wā, kei waenga i te 4kg me te 5kg. 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, ā, he nui ake te utu mō te moata, nō reira he nui te 150,000 yuan. Ā, ko te mahi nui rawa atu a te HPMC ko te pupuri wai, ā, muri iho ko te whakamātotoru. I roto i te paura putty, mena he pai te pupuri wai me te iti o te matotoru (70,000-80,000), he pai. Ko te tikanga, ko te teitei ake o te matotoru, ko te pai ake o te pupuri wai. Ina neke atu te matotoru i te 100,000, he iti noa te pānga o te matotoru ki te pupuri wai.

7. He aha ngā tohu hangarau matua o te hydroxypropyl methylcellulose (HPMC)?

——A: Mō te nui o te hauwaiporoporo me te matotoru, he maha ngā kaiwhakamahi e āwangawanga ana mō ēnei tohu e rua. Ko te nui ake o te hauwaiporoporo, ko te pai ake o te pupuri wai. Mēnā he matotoru teitei, he pai ake te pupuri wai (ehara i te tino), ā, mēnā he 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 houra tunutunu, te waikawa, te toluene, te waipiro isopropyl, me ētahi atu.

9. He aha te mahi matua a te HPMC i roto i te whakamahinga o te paura putty? He pānga matū kei a ia?

——Whakautu: E toru ngā mahi matua a te HPMC, arā, te whakamātotoru, te pupuri wai me te hanga i roto i te paura putty. Te whakamātotoru: Ka taea e te cellulose te whakamātotoru i te wairewa, te pupuri i te otinga kia ōrite, me te ātete ki te totohu. Te pupuri wai: Ka āta whakamaroke te paura putty, ā, ka āwhina i te tauhohenga o te konupūmā hina i raro i te mahi a te wai. Te Hanganga: He pānga whakahinuhinu te cellulose, ā, ka taea e ia te hanga i te paura putty kia pai te mahi. Kāore te HPMC e whai wāhi ki ngā tauhohenga matū, ā, he mahi āwhina anake tāna. Ina tāpirihia te paura putty ki te wai, ka pania ki te pakitara, ka puta he tauhohenga matū. I te hanganga o tētahi matū hou, ka tangohia te paura putty i runga i te pakitara mai i te pakitara, ka hurihia hei paura i mua i te whakamahinga. Kāore tēnei e mahi nā te mea kua hangaia he matū hou (konupūmā kāponāte). Ko ngā wāhanga matua o te paura konupūmā hina ko: he ranunga o Ca(OH)2, CaO me te iti o CaCO3, CaO+H2O=Ca(OH)2 -Ca(OH)2+CO2=CaCO3↓+H2O Ka rewa te konupūmā hina ki te wai me te hau CO2 I raro i te mahi a te konupūmā kāponāte, ka pupuri noa te HPMC i te wai, ā, ka āwhina i te konupūmā hina kia pai ake te tauhohenga, ā, kāore e whai wāhi ki tētahi tauhohenga.

10. He etera cellulose kore-ionic te HPMC, nō reira he aha te mea kore-ionic?

A: Ki te kīanga māmā noa iho, ko ngā kore-iona he matū kāore e iona i roto i te wai. Ko te ionatanga te tukanga e wehea ai ngā irahiko hei iona e neke haere ana i roto i ētahi whakarewa (hei tauira, te wai, te waipiro). Hei tauira, ko te konutai pūhaumāota (NaCl), te tote e kainga ana i ia rā, ka rewa ki roto i te wai ka iona, ka puta he iona konutai (Na+) e neke haere ana, he iona pūhaumāota (Cl) e kore e nekeneke. Arā, ina whakanohoia te HPMC ki roto i te wai, kāore e wehea hei iona e iona ana, engari kei roto i te āhua ngota.
