He aha te Polyvinylpyrrolidone (PVP)?
Polyvinylpyrrolidone, whakarāpopototia ko PVP. E whakamahia ana hei āwhina, hei tāpiri, hei mea whakakī i roto i ngā mara maha pērā i te rongoā, te kakahu, te matū, te inu, me te matū o ia rā. E ai ki ngā whakaritenga hua, ka taea te wehewehe i te PVP ki ngā momo e whā: te taumata ahumahi, te taumata whakapaipai, te taumata kai, me te taumata rongoā. Ko ngā hua homopolymers, copolymers, me ngā hua raupapa polymer honohono-whiti me ngā taumaha ngota whanaunga mai i te mano ki te neke atu i te kotahi miriona kua whakamahia whānuitia nā ō rātou āhuatanga pai me te ahurei.
E whā ngā taumata o te PVP i runga i tōna taumaha ngota toharite, ā, e tohuhia ana e ngā uara K. Ko ngā uara K rerekē e tohu ana i te whānuitanga ōrite o te taumaha ngota toharite o te PVP. Ko te uara K he uara āhuatanga e pā ana ki te matotoru whanaunga o te wairewa PVP, ā, ko te matotoru he rahinga ā-tinana e pā ana ki te taumaha ngota o ngā polymer. Nō reira, ka taea te whakamahi i te uara K hei whakaahua i te taumaha ngota toharite o te PVP. I te nuinga o te wā, ko te nui ake o te uara K, ko te teitei ake o tōna matotoru me te kaha ake o tōna piri. Ka taea te whakarōpū i ngā momo hua matua me ngā whakaritenga o te PVP ki ngā taumata matotoru o te K-15, K17, K25, K-30, K60, me te K-90 i runga i te taumaha ngota.

PVP, hei pūhui pūmua wairewa-waihanga, he rite tonu ngā āhuatanga ki ngā pūhui pūmua wairewa-waihanga, tae atu ki te tiaki i te korori, te hanga kiriata, te here, te mimiti makuku, te whakarewatanga, te whakapūmau rānei. Heoi, ko tōna āhuatanga tino motuhake ko tōna wairewatanga pai me te hototahi ā-tinana, kua arohia. I roto i ngā pūmua hanga, ko te PVP, he wairewa ki te wai me te nuinga o ngā whakarewa waro, he iti te paitini, ā, he pai te hototahi ā-tinana, kāore i te kitea noa, inā koa i roto i ngā mara e pā tata ana ki te hauora tangata pēnei i te rongoā, te kai, me ngā mea whakapaipai. Koinei te whakataki motuhake ki ōna wāhi tono:
I roto i te mara o ngā mea whakapaipai o ia rā
I roto i ngā whakapaipai o ia rā, he pai te horapa o te PVP me te copolymer me te āhuatanga hanga kiriata. Ka taea e te PVP te tiaki i te colloid i roto i te hinu kiri, ā, ka taea te whakamahi i roto i ngā kirīmi ngako me ngā kirīmi kore-ngako, hei wai whakatakoto, hei rehu makawe me te kaihoko whakatakoto mousse, hei hinu ārai rā mō te makawe, hei whakaū pahuka hopi, hei kaihoko whakatakoto ngaru, me te kaihoko whakamarara tae makawe me te kaihoko piri. Mā te tāpiri i te PVP ki te kirīmi hukarere, te hinu ārai rā, me ngā kaihoko tango huruhuru ka taea te whakarei ake i ngā pānga mākū me te whakahinuhinu.
Mara horoi
He āhuatanga ārai-paru me te ārai-whakarewa anō te PVP, ā, ka taea te whakamahi hei hanga wai mārama, hei hanga hopi horoi paru taumaha rānei. He pai te pānga ārai-ngaro o te tae o te PVP ki ngā hopi horoi, ā, ka taea te whakapai ake i te kaha horoi. I te wā e horoi ana i ngā kakahu, ka taea te ārai i te whakapataritari o te kiri i ngā hopi horoi hangai, inā koa ngā muka hangai. He tino pai ake tēnei mahi i ngā hopi horoi carboxymethyl cellulose (CMC). Ka taea te whakakotahi i te PVP me te borax hei wāhanga whai hua i roto i te hanganga o ngā kaihoko horoi patu huakita phenolic. Ko te hopi horoi i hangaia mai i te PVP me te hauwai waikura he mahi whakama me te patu huakita.
Te tā me te tae i ngā kakahu
He pai te hononga o te PVP ki ngā tae rauropi maha, ā, ka taea te whakakotahi ki ngā muka hangai hydrophobic pērā i te polyacrylonitrile, ngā esters, te nairona, me ngā rauemi muka hei whakapai ake i te kaha tae me te hydrophilicity. Whai muri i te PVP me te nylon grafting copolymerization, ka pai ake te ātete o te papanga i hangaia ki te makuku me te ātete ki te makuku.
Ngā paninga me ngā tae
He mārama ngā peita me ngā paninga kua pania ki te PVP, engari kāore e pā ki te tae tūturu, ka whakapai ake i te kanapa me te marara o ngā paninga me ngā tae, ka whakarei ake i te pumau o te wera, me te whakapai ake i te marara o ngā waituhi me ngā mangumangu.
Marae hauora
He tino pai te koretake o te PVP i roto i te tinana, kāore e uru ki te pākia o te tangata, ā, he tino pai te hototahi ki te koiora, kāore e puta he riri ki te kiri, ki te kiriuhi mucosa, ki ngā kanohi, me ētahi atu. Ko te PVP kounga hauora tētahi o ngā tāpiri rongoā hou e toru e tautokona ana e te ao, ka taea te whakamahi hei here mō ngā papa me ngā granules, hei whakarewa tahi mō ngā werohanga, me te āwhina rere mō ngā capsules; Ngā mea tango paitini, ngā mea whakaroa, ngā mea whakahinuhinu me ngā kaihoko hanga kiriata mō ngā pata kanohi, ngā mea whakamarara mō ngā hanganga wai, ngā mea whakaū mō ngā whākōkī me ngā rongoā werawera, ā, ka taea hoki te whakamahi hei tiaki pāmahana-iti. Whakamahia mō ngā karaihe whakapā hei whakanui ake i tō rātou hydrophilicity me te hinu. Hei tāpiri, ka taea hoki te whakamahi i te PVP hei tae me te kaihoko rerekē hihi-X; Ka taea te whakamahi mō ngā momo momo rongoā pēnei i ngā papa, granules, me te wai. He mea tango paitini, he hemostasis, he whakanui ake i te kukū wairewa, he aukati i te piri o te peritoneal, me te whakatairanga i te tere o te whakatōtō erythrocyte. Kua whakarewahia mana te PVP K30 me te whakaaetanga a te tari whakahaere rongoā ā-motu.
Te tukatuka kai
Kāore te PVP e pāngia e te mate pukupuku, ā, he pai te haumaru o te kai. Ka taea e ia te hanga matatini me ngā matū polyphenolic motuhake (pērā i te tannins) ā, e whakamahia ana hei kaiwhakamārama me te whakau i roto i te tukatuka kai, pērā i te pia, te wai hua, me te waina. Ka taea e te PVP te hanga matatini me ngā matū polyphenolic motuhake (pērā i te tannins), e whai wāhi ana ki te whakamārama me te ārai toto i roto i ngā inu wai hua. He whānui te whakamahinga o te PVP honohono-whiti i roto i te pia me ngā inu tī. Ka taea e ngā matū polyphenolic i roto i te pia te herea ki ngā pūmua i roto i te pia hei hanga matatini macromolecular tannin, e tino pā kino ana ki te reka o te pia me te whakapoto i tōna roanga o te rokiroki. Ka taea e te polyvinylpyrrolidone honohono-whiti (PVPP) te hono ki te waikawa tannic me ngā anthocyanins i roto i te pia, mā reira ka whakamārama i te pia, ka whakapai ake i tōna pumau rokiroki, me te whakaroa i tōna roanga o te rokiroki. I roto i ngā inu tī, mā te whakamahinga o te PVPP ka taea te whakaiti tika i te ihirangi o ngā polyphenols tī, ā, kāore te PVPP e noho tonu i roto i ngā inu tī, ka taea ai te whakamahi anō me te whakaiti nui i ngā utu.
Ko ngā wāhi matua o te PVP kei roto i ngā ahumahi matū me te rongoā o ia rā, ā, ko te tipu o ēnei ahumahi e rua ka haere tonu te akiaki i te hiahia matua mō te kai PVP ā muri ake nei. I roto i te mara hou o te PVP, i roto i te ahumahi pākahiko lithium, ka taea te whakamahi i te PVP hei whakamarara mō ngā irahiko pākahiko lithium me te āwhina tukatuka mō ngā rauemi kawe hiko; I roto i te ahumahi photovoltaic, ka taea te whakamahi i te PVP hei whakamarara hei whakaputa paura hiriwa porowhita kounga teitei mō te whakapiri hiriwa irahiko pai, te paura hiriwa rite-pepa mō te whakapiri hiriwa irahiko kino, me ngā matūriki hiriwa nano. Mā te whakapai tonu i te tere urunga o te pākahiko lithium me te pikinga o te kaha tāuta photovoltaic, ka tino akiakihia e ēnei mara hou e rua te hiahia mō te PVP.
He kaiwhakarato ngaio a Unilong, ā, ko teRaupapa PVPKua tekau tau te roa o te whanaketanga me te whakaputanga. Nā ngā panonitanga o te mākete, kua iti te tuku o ngā hua PVP. I tēnei wā, kua tāpirihia e mātou ētahi atu raina whakaputa e rua, me te nui o te tuku me ngā utu pai. Tena koa, pātai mai.
