Polyvinylpyrrolidone ni iki (PVP)?

Polyvinylpyrrolidone, mu magambo ahinnye nka PVP. Polyvinylpyrrolidone (PVP) ni polymer idafite ionic yakozwe na polymerisation ya N-vinylpyrrolidone (NVP) mubihe bimwe. Ikoreshwa nk'inyongeramusaruro, inyongeramusaruro, kandi ishimishije mubice byinshi nk'ubuvuzi, imyenda, imiti, ibinyobwa, na chimique ya buri munsi. Ukurikije ibicuruzwa bisabwa, PVP irashobora kugabanywamo ubwoko bune: urwego rwinganda, urwego rwo kwisiga, urwego rwibiryo, nicyiciro cya farumasi. Homopolymers, copolymers, hamwe nibicuruzwa byahujwe na polymer ikurikirana hamwe nuburemere bwa molekuline ugereranije kuva ku bihumbi kugeza kuri miliyoni imwe yakoreshejwe cyane kubera imiterere myiza kandi idasanzwe.

PVP igabanijwemo inzego enye ukurikije uburemere bwacyo bwa molekuline, kandi ikunze kugaragazwa na K indangagaciro. Indangagaciro K zitandukanye zerekana urwego rujyanye nuburemere buringaniye bwa PVP. Agaciro K mubyukuri nigiciro kiranga isano ijyanye nubwiza bwikigereranyo cyamazi ya PVP, kandi viscosity numubare wumubiri ujyanye nuburemere bwa molekile ya polymers. Kubwibyo, K agaciro gashobora gukoreshwa kuranga impuzandengo ya molekuline ya PVP. Mubisanzwe, uko K agaciro kangana, niko kwiyongera kwayo no gukomera kwayo. Ubwoko bwibicuruzwa byingenzi nibisobanuro bya PVP birashobora gushyirwa mubice byijimye bya K-15, K17, K25, K-30, K60, na K-90 ukurikije uburemere bwa molekile.

UNILONG INDUSTRY irashobora gutanga ibi bikurikiraPVP-Kibicuruzwa bikurikirana ：

PVP, nk'amazi ya sintetike yamazi ya elegitoronike, afite imiterere rusange yimyunyu ngugu ya polymer, harimo kurinda colloid, gukora firime, guhuza, kwinjiza amazi, solubilisation cyangwa coagulation. Nyamara, umwihariko wacyo ni uburyo bwiza bwo gukemuka no guhuza umubiri, bikurura abantu. Muri polymrike ya sintetike, PVP, ibora mumazi ndetse no mumashanyarazi menshi, ifite uburozi buke, kandi ihuza neza na physiologique, ntibikunze kugaragara cyane cyane mubice bifitanye isano rya bugufi nubuzima bwabantu nkubuvuzi, ibiryo, na cosmetike. Ibikurikira nintangiriro yihariye kubisabwa:

Mu rwego rwo kwisiga buri munsi

Mu mavuta yo kwisiga ya buri munsi, PVP na copolymer bifite itandukaniro ryiza nibintu bikora firime. PVP irashobora kurinda colloid mumavuta yo kwisiga, kandi irashobora gukoreshwa mumavuta hamwe namavuta adafite ibinure, nko gushiraho amazi, gutera imisatsi hamwe nogushiraho mousse, icyuma cyogosha izuba, izuba ryogosha, shampoo foam stabilisateur, umukozi wo gushiraho imiraba, hamwe nogukwirakwiza amarangi yimisatsi hamwe na agent. Ongeraho PVP kuri cream cream, izuba ryizuba, hamwe nogukuraho umusatsi birashobora kongera ingaruka zo gusiga no gusiga.

Umwanya wo gukaraba

PVP ifite imiti igabanya ubukana n’imvura kandi irashobora gukoreshwa mugutegura amazi meza cyangwa ibintu byangiza cyane. Kongera PVP kumashanyarazi bifite ingaruka nziza zo kurwanya ibara kandi birashobora kongera ubushobozi bwisuku. Iyo woza imyenda, irashobora kubuza ibikoresho byo mu bwoko bwa sintetike kurakaza uruhu, cyane cyane fibre synthique. Iyi mikorere iragaragara cyane kuruta carboxymethyl selulose (CMC). PVP irashobora kongerwamo na borax nkigikoresho cyiza mugutegura imiti yica fenolike. Imashini igizwe na PVP na hydrogen peroxide ifite imirimo yo guhumanya no kwica bagiteri.

Gucapa imyenda no gusiga irangi

PVP ifitanye isano n’amabara menshi kama kandi irashobora guhuza hamwe na fibre synthique hydrophobique nka polyacrylonitrile, esters, nylon, nibikoresho bya fibrous kugirango bitezimbere imbaraga zo gusiga hamwe na hydrophilique. Nyuma ya PVP na nylon ishushanya copolymerisation, umwenda wakozwe wongereye imbaraga zo kurwanya ubushuhe no kurwanya ubushuhe.

Ibitambaro hamwe na pigment

Irangi hamwe nigitambaro bisize hamwe na PVP birasobanutse neza bitagize ingaruka kumiterere yabyo, kunoza ububengerane no gukwirakwiza ibishishwa hamwe na pigment, kuzamura ubushyuhe bwumuriro, no kunoza itandukanyirizo rya wino na wino.

Urwego rwubuvuzi

PVP ifite ubudahangarwa bwiza bwa physiologique, ntabwo yitabira metabolism yabantu, kandi ifite biocompatibilité nziza, idatera uburakari ubwo aribwo bwose kuruhu, mucosa, amaso, nibindi. Irashobora gukoreshwa nka binder ya tableti na granules, co solvent yo gutera inshinge, hamwe nubufasha bwo gutembera kuri capsules; Imiti yangiza, iyagura, amavuta yo kwisiga hamwe nogukora firime kumatonyanga yijisho, ikwirakwiza kumazi, stabilisateur ya enzymes nibiyobyabwenge bya termosensitivite, kandi birashobora no gukoreshwa nkubushyuhe buke. Ikoreshwa muburyo bwo guhuza kugirango yongere hydrophilicity na lubricity. Mubyongeyeho, PVP irashobora kandi gukoreshwa nkibara ryerekana amabara na X-ray; Irashobora gukoreshwa muburyo butandukanye bwibiyobyabwenge nkibinini, granules, namazi. Ifite ubumara, hemostasis, kongera imbaraga zo gusesa, kwirinda gufatira kwa peritoneal, no kuzamura igipimo cy’imitsi ya erythrocyte. PVP K30 yatangijwe kumugaragaro byemejwe nishami ryigihugu rishinzwe imiti.

Gutunganya ibiryo

PVP ubwayo ntabwo ari kanseri kandi ifite umutekano mwiza wibiryo. Irashobora gukora ibice bifite ibice byinshi bya polifenolike (nka tannine) kandi ikoreshwa cyane nkibintu bisobanutse kandi bihamye mugutunganya ibiryo, nka byeri, umutobe wimbuto, na vino. PVP irashobora gukora ibice bifite polifenolike yihariye (nka tannine), bigira uruhare rusobanutse kandi rurwanya antikagulant mubinyobwa by umutobe wimbuto. Ikoreshwa rya PVP ihuza inzoga n'ibinyobwa byicyayi birakwirakwira cyane. Ibintu bya polifenolike muri byeri birashobora guhuza na poroteyine ziri mu nzoga kugira ngo bibe uruganda rwa tannin macromolecular, bigira ingaruka zikomeye ku buryohe bwa byeri kandi bikagabanya igihe cyo kubaho. Polyvinylpyrrolidone ihujwe (PVPP) irashobora gushiramo aside tannic na anthocyanine muri byeri, bityo igasobanura byeri, igahindura neza ububiko bwayo, kandi ikongerera igihe cyayo. Mu binyobwa byicyayi, gukoresha PVPP birashobora kugabanya neza ibikubiye muri polifenol yicyayi, kandi PVPP ntiguma mubinyobwa byicyayi, bigatuma ikoreshwa kandi bikagabanya cyane ibiciro.

Ibice byingenzi bikoreshwa muri PVP byibanze cyane mubikorwa bya chimique na farumasi ya buri munsi, kandi izamuka ryinganda zombi zizakomeza gutwara icyifuzo gikenewe cyo gukoresha PVP mugihe kizaza. Mu murima ugaragara wa PVP, mu nganda za batiri ya lithium, PVP irashobora gukoreshwa nk'ikwirakwizwa rya electrode ya lithium na mfashanyo yo gutunganya ibikoresho bitwara; Mu nganda zifotora, PVP irashobora gukoreshwa nkikwirakwiza kugirango itange ifu nziza yo mu rwego rwo hejuru ifu ya feza nziza ya elegitoronike ya feza, ifu imeze nk'ifeza ya silver ya paste mbi ya electrode, hamwe na nano ya silver. Hamwe nogukomeza kunoza igipimo cya batiri ya lithium no kwiyongera kwubushobozi bwa fotovoltaque, iyi mirima yombi igaragara izatera cyane PVP.

Unilong ni umutanga wabigize umwuga, naUrukurikirane rwa PVPyatejwe imbere kandi ikorwa imyaka icumi. Hamwe nimpinduka kumasoko, itangwa ryibicuruzwa bya PVP rirahari. Kugeza ubu, twongeyeho indi mirongo ibiri yumusaruro, hamwe nibitangwa bihagije nibiciro byiza. Nyamuneka ndakwinginze ubaze.
