He aha te hydroxypropyl methyl cellulose?
Te hauwaiporoporo metila (HPMC), e mōhiotia ana ko te hydroxypropyl methylcellulose, cellulose hydroxypropyl methyl ether, cellulose, 2-hydroxypropylmethyl ether, PROPYLENE GLYCOL ETHER OF METHYLCELLULOSE, CAS No. 9004-65-3, he mea hanga mai i te cellulose miro tino parakore mā te etherification motuhake i raro i ngā āhuatanga kawakore. Ka taea te wehewehe i te HPMC ki te taumata hanga, te taumata kai me te taumata rongoā e ai ki tōna whakamahinga. He whānuitia te whakamahinga i roto i te hanganga, te kai, te rongoā me ngā mea whakapaipai, ngā matū o ia rā me ētahi atu ahumahi.
He aha ngā whakamahinga o te HPMC?
Ahumahi hangahanga
1. Moata pereki
Mā te whakapakari i te piri ki te mata o te pereki ka taea te pupuri i te wai, ka whakapai ake i te kaha o te moata, ka whakapai ake hoki i te hinu me te kirihou hei āwhina i te mahi hanga. Mā te ngāwari o te hanga ka penapena wā, ka pai ake hoki te whai hua o te utu.
2. Ngā hua gypsum
Ka taea e ia te whakaroa i te wā mahi o te moata, ā, ka whakaputa i te kaha ā-pūkaha teitei ake i te wā e totoka ana. Ka hangaia he paninga mata kounga teitei mā te whakahaere i te matotoru o te moata.
3. Peita wai me te tango peita
Ka taea e ia te whakaroa i te roa o te wā e mau ana mā te aukati i te maturuturunga totoka, ā, he tino hototahi, he pumau koiora teitei hoki. He tere te tere whakarewa, ā, kāore e ngāwari te whakakotahi, he mea āwhina ki te whakahaere i te tukanga whakaranu. Ka whakaputa i ngā āhuatanga rere pai, tae atu ki te iti o te tauhiuhi me te whakataurite pai, ka whakarite kia pai te mutunga o te mata, ā, ka ārai i te totohu o te peita. Ka whakarei ake i te matotoru o te tango peita wai-pūtake me te tango peita whakarewa waro, kia kore ai te tango peita e rere atu i te mata o te mea mahi.
4. Piripiri tāera uku
He māmā te whakaranu i ngā kai maroke, ā, kāore e pupū ake, ka penapena i te wā mahi nā te mea he tere ake, he whai hua ake hoki te whakamahinga, ka pai ake te tukatuka me te whakaiti i ngā utu. Ka whakapai ake i te pai o te tāera, ā, ka pai ake te piri mā te whakaroa i te wā whakamatao.
5. Ngā rauemi papa whakaōrite-ake
Ka whakarato i te matotoru, ā, ka taea te whakamahi hei tāpiri ārai-taunga hei āwhina i te whakapai ake i te whai huatanga o ngā papa. Mā te whakahaere i te pupuri wai ka tino whakaiti i ngā kapiti me te mimiti.
6. Te hanga i ngā pereti raima kua hangaia
Ka whakarei ake i te ngāwari o te tukatuka o ngā hua kua peia, he kaha te piri me te whakahinuhinu, ā, ka whakapai ake i te kaha mākū me te piri o ngā pepa kua peia.
7. Whakakī hononga pereti
He tino pai te pupuri wai o te Hydroxypropyl methyl cellulose, ka taea te whakaroa i te wā whakamatao, ā, nā te kaha o te hinu whakahinuhinu ka maeneene ake te paninga. Ka whakapai ake i te kounga o te mata, ka maeneene, ka ōrite te kakano, ā, ka pakari ake te mata piri.
8. Kapia i hangaia ki te sima
He nui te pupuri wai, he roa ake te wā mahi o te moata, ā, ka taea hoki te whakahaere i te urunga o te hau, kia kore ai e pakaru ngā kapiti moroiti o te paninga, kia maeneene ai te mata.
Ahumahi kai
1. Ngā hua citrus kēne: hei ārai i te mā me te pirau nā te pirau o ngā glycosides citrus i te wā e rongoa ana, kia mau tonu ai te hou.
2. Ngā hua hua matao: ka tāpirihia ki te wai hua me te hukapapa kia pai ake ai te reka.
3. Ranu: whakamahia hei whakau i te ranu me te whakapiri tōmato.
4. Te paninga me te whakakanapa i te wai matao: whakamahia mō te rokiroki ika tio hei ārai i te hurihanga me te hekenga o te kounga. I muri i te paninga me te whakakanapa ki te wai methyl cellulose, ki te wai hydroxypropyl methyl cellulose rānei, whakakanapahia ki runga i te paparanga hukapapa.
5. Piripiri mō ngā papa: Hei piripiri hanga mō ngā papa me ngā granules, he pai te "hinganga ngātahi" (te tere o te memeha, te hinga me te marara i te wā e tangohia ana).
Ahumahi rongoā
1. Te Whakakī: Ka hangaia te kaihoko whakakī hei otinga o te whakarewa waro, hei otinga wai rānei mō te whakahaere papa, inā koa mō te whakakī rehu o ngā matūriki kua whakaritea.
2. Kaihoko whakaroa: 2-3 karamu ia rā, 1-2 karamu ia wā, mō ngā rā 4-5.
3. Rongoā kanohi: Nā te mea he rite te pēhanga osmotic o te wairewa methyl cellulose ki te pēhanga o ngā roimata, kāore e tino whakapataritari i ngā kanohi. Ka tāpirihia ki roto i te rongoā kanohi hei hinu whakahinuhinu mō te pa atu ki te karāhe kanohi.
4. He tiēre: Ka whakamahia hei rauemi pūtake mō te tiēre, pērā i te rongoā o waho, i te hinu rānei.
5. Kaiwhakakī wai: whakamahia hei whakamātotoru me te pupuri wai.
Ahumahi whakapaipai
1. Horoi horoi: Whakapai ake i te matotoru me te pumau o te hopi horoi, te kaihoroi me te hopi horoi.
2. Paraihe niho: whakapai ake i te rere o te paraihe niho.
Ahumahi oumu
1. Rauemi hiko: hei piripiri hanga-pēhi o te miihini whakakī hiko uku me te aukume bauxite ferrite, ka taea te whakamahi tahi me te 1.2-propanediol.
2. Rongoā paninga: whakamahia hei rongoā paninga o ngā uku, ā, ka whakamahia ngātahitia me te peita enamel, ka taea te whakapai ake i te hononga me te ngāwari o te tukatuka.
3. Moata ātete: Ka taea te tāpiri atu ki te moata pereki ātete, ki te rauemi oumu whakarewa rānei hei whakapai ake i te kirihou me te pupuri wai.
Ētahi atu ahumahi
E whakamahia whānuitia ana hoki te HPMC i roto i te kapia hangai, te matū hinu, te uku, te hanga pepa, te hiako, te waituhi wai, te tupeka me ētahi atu ahumahi. E whakamahia ana hei whakamātotoru, hei whakamarara, hei here, hei whakapūmau me te whakau i roto i te ahumahi kakahu.
Me pēhea te tirotiro ā-kanohi i te kounga o te hydroxypropyl methyl cellulose (HPMC)?
1. Te Āhuatanga o te Tae: ahakoa kāore e taea te tautuhi tika mēnā he ngāwari te whakamahi i te HPMC, ā, mēnā ka tāpirihia he mea whakama ki te hanga, ka pāngia tōna kounga. Heoi, kei te tata te hoko i ngā hua kounga teitei.
2. Te Maeneene: E 80 ngā mata o te HPMC, e 100 ngā mata i te nuinga o te wā, ā, he iti iho ngā mata 120. He 80 ngā mata o te nuinga o ngā HPMC. I te nuinga o te wā, he pai ake te maeneene o waho.
3. Te whakawhiti mārama: tāpirihia te hydroxypropyl methyl cellulose (HPMC) ki roto i te wai hei hanga i tētahi kōroiti mārama, kātahi ka kite i tōna whakawhiti mārama. Ko te nui ake o te whakawhiti mārama, ko te pai ake, e tohu ana he iti ake te matū kore-rewa i roto.
4. Taumaha motuhake: Ko te taumaha motuhake, ko te pai ake. He mea nui te ōwehenga, i te nuinga o te wā nā te mea he nui te ihirangi o te hydroxypropyl. Mena he nui te ihirangi o te hydroxypropyl, he pai ake te pupuri wai.
He pumau te Hydroxypropyl methyl cellulose ki ngā waikawa me ngā kawakore, ā, he tino pumau tōna wairewa i roto i te awhe pH=2~12. He kaihanga ngaio mātou. Mena kei te hiahia koe ki tēnei hua, whakapā mai ki a mātou. Koinā katoa hei whakapuakitanga mā te HPMC i roto i tēnei putanga. Ko tāku tumanako ka āwhina i a koe ki te mārama ki te HPMC.
