Polyvinylpyrrolidone (PVP) ni iki?

Polyvinylpyrrolidone, mu magambo make nka PVP. Ikoreshwa nk'inyongeramusaruro, inyongeramusaruro, n'inyongeramusaruro mu nzego nyinshi nko mu buvuzi, mu myenda, mu bya shimi, mu binyobwa, no mu bya shimi bya buri munsi. Dukurikije ibisabwa ku bicuruzwa, PVP ishobora kugabanywamo ubwoko bune: urwego rw'inganda, urwego rw'ubwiza, urwego rw'ibiribwa, n'urwego rw'imiti. Ibicuruzwa bya homopolymer, copolymer, n'ibicuruzwa bya polymer bifitanye isano bifite uburemere bwa molekile kuva ku bihumbi kugeza ku birenga miliyoni imwe byakoreshejwe cyane kubera imiterere yabyo myiza kandi yihariye.

PVP igabanyijemo urwego rune hashingiwe ku buremere bwayo mpuzandengo bwa molekile, kandi ikunze kugaragazwa n'agaciro ka K. Agaciro ka K gatandukanye kagaragaza urwego rujyanye n'uburemere mpuzandengo bwa molekile ya PVP. Agaciro ka K mu by'ukuri ni agaciro karanga gafitanye isano n'uburemere bw'amazi ya PVP, kandi uburemere ni ingano ifatika ijyanye n'uburemere bwa molekile za polymer. Kubwibyo, agaciro ka K gashobora gukoreshwa mu kugena uburemere mpuzandengo bwa molekile ya PVP. Ubusanzwe, uko agaciro ka K kaba kanini, niko uburemere bwayo burushaho kwiyongera kandi ikagira imbaraga zo gufatana. Ubwoko bw'ibicuruzwa by'ingenzi n'ibipimo bya PVP bishobora gushyirwa mu byiciro by'uburemere bwa K-15, K17, K25, K-30, K60, na K-90 hashingiwe ku buremere bwa molekile.

INGANDA YA UNILONG ishobora gutanga ibi bikurikiraPVP-Kibicuruzwa bikurikirana:

PVP, nk'umusemburo wa polymer ushongesha amazi mu buryo bw'ubukorano, ufite imiterere rusange y'umusemburo wa polymer ushongesha amazi, harimo kurinda kolloidi, gukora filime, guhuza, kwinjiza ubushuhe, gushonga cyangwa gufungana. Ariko, ikintu kiyiranga cyane ni uburyo ishongesha neza no guhuza neza n'imiterere y'umubiri, byakuruye abantu benshi. Muri polymer zikozwe mu buryo bw'ubukorano, PVP, ishongesha mu mazi no mu bintu byinshi bishongesha umubiri, ifite uburozi buke, kandi ihuye neza n'imiterere y'umubiri, ntabwo ikunze kugaragara, cyane cyane mu nzego zifitanye isano rya hafi n'ubuzima bw'abantu nko mu buvuzi, mu biribwa, no mu mavuta yo kwisiga. Ibi bikurikira ni ibanze ryihariye ry'aho ikoreshwa:

Mu rwego rwo kwisiga buri munsi

Mu mavuta yo kwisiga ya buri munsi, PVP na copolymer bifite ubushobozi bwo gutandukanya no gukora filime. PVP ishobora kurinda colloid mu mavuta yo kwisiga, kandi ishobora gukoreshwa mu mavuta yo kwisiga n'atari amavuta, nk'amavuta yo kwisiga, spray y'umusatsi na mousse, sunscreen conditioner, shampoo foam stabilizer, wave setting agent, na affinant indorerwamo y'irangi ry'umusatsi na affinity. Kongeramo PVP muri snow cream, sunscreen, na agents zo gukuraho umusatsi bishobora kongera ingaruka zo kunyagirwa no gusiga amavuta.

Aho gukaraba

PVP ifite ubushobozi bwo kurwanya ihumana no gusubira mu mvura kandi ishobora gukoreshwa mu gutegura ibinyobwa bibonerana cyangwa amasabune akomeye ahumanya. Kongeramo PVP mu masabune bifite ingaruka nziza zo kurwanya ibara ry'uruhu kandi bishobora kongera ubushobozi bwo gusukura. Mu kumesa imyenda, bishobora gukumira amasabune akoze mu nganda kurakara uruhu, cyane cyane imigozi ikoze mu nganda. Iyi mikorere irahebuje kurusha amasabune ya carboxymethyl cellulose (CMC). PVP ishobora kuvangwa na borax nk'ikintu cyiza mu gukora imiti isukura imiti yica udukoko ya phenolic. Isabune igizwe na PVP na hydrogen peroxide ifite akazi ko gusiba no kwica bagiteri.

Gucapa no gusiga amarangi ku myenda

PVP ifite isano ryiza n’amabara menshi y’umwimerere kandi ishobora guhuzwa n’imigozi ya sintetike idafite amazi nka polyacrylonitrile, esters, nylon, n’ibikoresho bya fibre kugira ngo yongere imbaraga zo gusiga irangi no kuvura amazi. Nyuma yo gukoresha PVP na nylon grafting copolymerization, umwenda wakozwe wongereye ubushobozi bwo kudasiga amazi no kudasiga amazi.

Irangi n'amabara

Amarangi n'amabara asizweho PVP birabonerana nta ngaruka ku ibara ryabyo karemano, bikongera ububengerane n'uburyo amabara n'amabara akwirakwira, byongera ubushyuhe, kandi bikongera uburyo amabara n'amabara akwirakwira.

Urwego rw'ubuvuzi

PVP ifite ubushobozi bwo kudakora neza kw'umubiri, ntigira uruhare mu mikorere y'umubiri w'umuntu, kandi ifite ubushobozi bwo guhuza neza n'ibinyabuzima, idatera ububabare ku ruhu, mucosa, mu maso, n'ibindi. PVP yo mu rwego rw'ubuvuzi ni imwe mu miti itatu mishya ikoreshwa mu buvuzi ikundwa ku rwego mpuzamahanga, ishobora gukoreshwa nk'ikintu gifunga ibinini n'uduhu, umuti wo gutera inshinge, n'umuti ufasha mu gutemba uduce duto; Ibinyabutabire, ibisigazwa, amavuta n'ibintu bitanga filime ku bitonyanga by'amaso, ibinyabutabire byo gukora imisemburo y'amazi, ibitera imbaraga enzymes n'imiti ikoresha thermosensitive, kandi ishobora no gukoreshwa nk'ibintu bigabanya ubushyuhe. Ikoreshwa mu ma lense kugira ngo yongere ubushobozi bwo gushonga no gusya. Byongeye kandi, PVP ishobora kandi gukoreshwa nk'umuti ugabanya ibara n'imiti igabanya ubushyuhe bwa X-ray; Ishobora gukoreshwa mu bwoko butandukanye bw'imiti nk'ibinini, uduhu, n'amazi. Ifite ubushobozi bwo gusukura, gushonga, kwiyongera k'umuvuduko wo gushonga, gukumira gufatana kw'uturemangingo, no guteza imbere igipimo cyo gushonga kwa erythrocyte. PVP K30 yatangijwe ku mugaragaro byemejwe n'ishami ry'igihugu rishinzwe kugenzura imiti.

Gutunganya ibiribwa

PVP ubwayo ntabwo itera kanseri kandi ifite umutekano mwiza mu biribwa. Ishobora gukora ubwoko butandukanye bw’ibinyabutabire bya polyphenolic (nk’ibinyabutabire bya tannins) kandi ikoreshwa cyane cyane nk’ikintu gitunganya no gushimangira ibiribwa, nk’inzoga, umutobe w’imbuto, na divayi. PVP ishobora gukora ubwoko butandukanye bw’ibinyabutabire bya polyphenolic (nk’ibinyabutabire bya tannins), bigira uruhare mu gusesengura no kurwanya amaraso mu binyobwa by’imbuto. Gukoresha PVP ifitanye isano n’ibinyabutabire mu binyobwa by’inzoga n’icyayi ni ibintu bikunze gukoreshwa cyane. Ibintu bya polyphenolic mu byeri bishobora gufatana na poroteyine mu byeri bigatuma habaho ubwoko butandukanye bwa tannin, bigira ingaruka zikomeye ku buryohe bwa byeri kandi bikagabanya igihe cyo kubikora. Polyvinylpyrrolidone (PVPP) ishobora guterana na aside tannic na anthocyanins mu byeri, bityo bikanoza inzoga, bikanoza uburyohe bwayo bwo kubika, kandi bikongera igihe cyo kubikora. Mu binyobwa by’icyayi, ikoreshwa rya PVPP rishobora kugabanya ingano ya polyphenolic mu byayi, kandi PVPP ntiguma mu binyobwa by’icyayi, bigatuma ishobora kongera gukoreshwa kandi bikagabanya cyane ikiguzi.

Ahantu hakoreshwa cyane muri PVP ubu hibandwa cyane mu nganda zikora imiti n'imiti buri munsi, kandi iterambere ry'izi nganda zombi rizakomeza guteza imbere icyifuzo cy'ingenzi cyo gukoresha PVP mu gihe kizaza. Mu rwego rwo kuzamuka rwa PVP, mu nganda zikora bateri ya lithium, PVP ishobora gukoreshwa nk'icyuma gikwirakwiza amashanyarazi ya bateri ya lithium n'igikoresho cyo gutunganya ibikoresho bitwara umuriro; Mu nganda zikora photovoltaic, PVP ishobora gukoreshwa nk'icyuma gikwirakwiza amashanyarazi kugira ngo ikore ifu nziza y'ifeza ikozwe mu buryo bwa electrode nziza, ifu y'ifeza isa n'urupapuro rw'ifeza rukozwe mu buryo bwa negative electrode, n'uduce twa nano ifeza. Hamwe no kunoza uburyo bateri ya lithium yinjiramo no kwiyongera k'ubushobozi bwa photovoltaic, izi nganda zombi zizaba zirimo gutera imbere cyane icyifuzo cya PVP.

Unilong ni umutanga serivisi w'umwuga, kandiUrukurikirane rwa PVPimaze imyaka icumi itunganywa kandi ikorwa. Bitewe n'impinduka ku isoko, umusaruro w'ibicuruzwa bya PVP urakennye. Ubu, twongeyeho indi mirongo ibiri y'umusaruro, hamwe n'umusaruro uhagije n'ibiciro byiza. Nyamuneka mubaza.
