amakuru

PolyvinylpyrrolidoneImiterere ya shimi (PVP) irimo impeta ya pyrrolidone, itanga ubushobozi bwo gushonga neza mu mazi, ubushobozi bwo gukora filime, gufatana, no guhuza umubiri.

"K25″ muri PVP K25 yerekana uburemere bwayo bwa molekile, aho "agaciro ka K" ari ikimenyetso cy'ingenzi cy'uburemere bwa molekile ya PVP. Agaciro ka K kari hejuru gahuye n'uburemere bwa molekile n'uburemere bwinshi. K25 iri mu rugero rwo hagati rw'uburemere bwa molekile, igaragaza ubushobozi bwo gushonga mu bintu nk'amazi, etanoli, na asetone.

Porogaramu z'ingenzi za PVP K25

Bitewe n'uburemere bwayo bungana bwa molekile, imiterere yayo yo gufatana, n'uburyo ishonga,PVP K25ikoreshwa cyane mu miti, amavuta yo kwisiga, n'inganda:

Urwego rw'imiti

Ibikoresho byo kubika ibinini: Bishongeshejwe mu mazi cyangwa mu ethanol, bifasha ifu y'imiti kwihuza n'utubuto, bigatuma ibinini bikomera kandi bigashonga.

Umushongi n'umushongi: Byongera ubushobozi bwo gushonga kw'imiti idashonga neza binyuze mu gukora complexes, bityo bikongera ubushobozi bwo kuboneka.

Filimi Yahozeho: Ikoreshwa mu buryo bwo kugenzura irekurwa ry'imiti cyangwa mu bice by'uruhu kugira ngo igenzure irekurwa ry'imiti.

Iby'ubwiza n'ubuvuzi bw'umuntu ku giti cye

Kwita ku ruhu no kwita ku musatsi: Bikora nk'ibikomeza ubushyuhe, bigabanya ubushyuhe, cyangwa bihindura imiterere y'umusaruro, bikongera imiterere y'umusaruro kandi bigafasha ko ibintu bikora bikwirakwira neza.

Ibikoresho byo gutunganya imisatsi (urugero: gels zo mu musatsi, mascaras): Bifasha cyane kandi byoroshye kubikuraho bitewe n’uko bikuramo filime kandi bigashonga mu mazi.

Porogaramu zo mu nganda

Irangi n'inyi: Bikora nk'ikintu gikwirakwiza kandi gikonjesha, gituza ibara kandi gikomeza gufatana kw'irangi.

Inganda z'imyenda: Ikoreshwa mu gutunganya imyenda kugira ngo yongere ubwiyongere n'imikorere yo kurwanya imihindagurikire y'ikirere.

Ibikoresho bya elegitoroniki: Bikora nk'icyuma gifunga cyangwa gikwirakwiza umuriro mu gukora bateri cyangwa ibice byayo, bigatuma habaho gutwikira electrode imwe.

Imikorere myiza ya PVP K25 ni myiza cyane

Nk'umuti usanzwe ukoreshwa mu buvuzi, inyungu nyamukuru ya PVP K25 iri mu "kuringaniza" hagati y'imbaraga zayo zo gufunga n'ubukana bw'umuti:

Gufata neza ibinini, bishimangira ko ibinini ari byiza: Bishobora gufatanya neza ifu y'imiti n'ibindi bikoresho (nk'ibyuzuza, ibisenya), bigatuma habaho uduce duto tudahindagurika mu miterere. Ubukana bw'ibinini byakaswe bwujuje ubuziranenge kandi ntibikunda kwangirika, bigagabanya ibibazo nk'ibinini byacitse kandi birekuye mu gihe cyo kubitunganya. Bikwiriye cyane cyane ibinini bifite ibisabwa kugira ngo bikomere (nk'ibinini by'imiti bifite urugero runini n'ibinini by'ifu igoye gukora).

Ubushyuhe buke bw'umuti, bworoshye gushonga no gufata Ugereranyije n'ubwoko bwinshi bwa PVP (nka PVP K30, PVP K90), K25 ifite uburemere buke bwa molekile. Ubushyuhe bwayo bw'amazi cyangwa umuti w'umwimerere (nka ethanol) bufite ubushyuhe buke, bushonga vuba, kandi ntabwo bushobora gukora "ibibyimba" mu gihe cyo gushonga, bigatuma bivangwa neza. Muri icyo gihe, bigabanya ingorane mu mikorere y'ibikoresho (nk'udupira, imashini zikoresha tableti) kandi bikongera ubushobozi bwo gukora.

Ni gute PVP K25 ifite umutekano?

PVP K25ni umuti ugabanya ubukana bw’imiti ufite umutekano wemejwe neza, wujuje ibisabwa mu bihugu byinshi ku isi. Amakuru y’uburozi ashyigikira uburozi bwayo buke, kutiyongera no kudatera umujinya. Imyitwarire yayo mu mubiri irasobanutse neza kandi ntibangamira. Hamwe n’imyaka myinshi imaze ikoreshwa mu buvuzi, bishobora gufatwa nk’aho ku gipimo gisanzwe cy’imiti, umutekano wayo uri hejuru cyane, bigatuma iba amahitamo yizewe y’umuti mu rwego rw’imiti.

Icyitonderwa ni uko umutekano w'ibikoresho bifasha imiti ugomba gusuzumwa neza hamwe n'uburyo rusange bw'umuti runaka (nk'ibindi bikoresho bifasha imiti, ibintu bikora ku muti). Umutekano w'umuti umwe ntabwo ugaragaza umutekano rusange w'umuti. Amaherezo, ikoreshwa rigomba gukurikiza amabwiriza ari ku kirango cy'umuti.

Muri rusange,PVP K25ni polymeri ifite uburemere buringaniye kandi bufite ubushobozi bwo gukora kole n'imashini. Igira uruhare runini mu miti, amavuta yo kwisiga, no mu nganda, cyane cyane nk'ikintu gifunga, gishonga, kandi gikwirakwiza mu buryo bwo gukora, bigatuma iba igikoresho cy'ingenzi cy'inyongera mu bicuruzwa bikoreshwa n'abaguzi n'inganda.
