Muminda yekugadzira nesainzi yemidziyo, kutsvaga kwekusimudzira kukwezva uye kushanda kwezvigadzirwa hakuperi. Imwe tsvarakadenga iri kuwana kukwezva kukuru ndeye kushandiswa kwemagetsi ekupenya, kunyanya mumapurasitiki. Nekudaro, mubvunzo wakajairika unouya ndewekuti zvinopenya zvinopenya zvakafanana ne bleach. Ichi chinyorwa chine chinangwa chekudzima mazwi aya uye kuongorora mabasa awo, mashandisiro, uye mutsauko.
Chii chinonzi optical brightener?
Optical brighteners, inozivikanwawo sefluorescent whitening agents (FWA), makomisheni anotora ultraviolet (UV) mwenje uye anoiburitsa zvakare sechiedza chinooneka cheblue. Iyi nzira inoita kuti zvinhu zvioneke zvakachena uye zvinopenya mumaziso emunhu. Optical brighteners inoshandiswa mumhando dzakasiyana-siyana dzemaindasitiri, kusanganisira machira, detergents uye mapurasitiki.
Panyaya yemapurasitiki, zvinopenya zvinopenya zvinowedzerwa panguva yekugadzira kusimudzira kukwezva kwechigadzirwa chekupedzisira. Zvinonyanya kubatsira mukuita kuti zvinhu zvepurasitiki zvitaridzike zvakachena uye zvakanyanya kusimba, zvichibhadhara chero kutsvuka kana kupera simba kunogona kuitika nekufamba kwenguva.
Ko zvinopenya zvinopenya zvinoshanda sei?
Sainzi iri shure kwekupenya kwemaziso ine midzi mu fluorescence. Kana mwenje we ultraviolet ukarova pamusoro pezvigadzirwa zvepurasitiki zvine zvinopenya zvinopenya, komboni yacho inotora ultraviolet mwenje woiburitsa zvakare sechiedza chinooneka chebhuruu. Chiedza chebhuruu ichi chinodzima chero ruvara rweyero, zvichiita kuti plastiki itaridzike yakachena uye iwedzere kusimba.
Kushanda kweoptical brightenerszvinoenderana nezvinhu zvakati wandei, zvinosanganisira rudzi rwepurasitiki, kuwanda kweiyo inopenya, uye chaiyo kugadzirwa kwekomboni. Kazhinji optical brighteners anoshandiswa mumapurasitiki anosanganisira stilbene derivatives, coumarins uye benzoxazoles.
Kushandiswa kwefluorescent whitening agents mumapurasitiki
Optical brighteners anoshandiswa zvakanyanya muzvigadzirwa zvepurasitiki, zvinosanganisira:
1. Packaging Materials: Ita kurongedza zvakanyanya kutaridzika uye kuwedzera kutaridzika kwechigadzirwa mukati.
2. Zvinhu Zvemumba: Zvakadai semidziyo, midziyo, fenicha, zvichingodaro, chengetedza chitarisiko chakachena uye chinopenya.
3. Auto Parts: Kuvandudza aesthetics yemukati nekunze zvikamu.
4. Electronics: Iva nechokwadi chekutaridzika, kutaridzika kwemazuva ano muimba uye zvimwe zvikamu.
Ko zvinopenya zvinopenya zvakafanana ne bleach?
Mhinduro pfupi ndeyokuti kwete; optical brighteners uye bleach hazvina kufanana. Nepo ese ari maviri achishandiswa kukwidziridza kutaridzika kwechinhu, anoshanda kuburikidza nemaitiro akasiyana zvachose uye anoshandira zvinangwa zvakasiyana.
Chii chinonzi bleach?
Bleach ikemikari yemakemikari inonyanya kushandiswa kuuraya utachiona uye kuchena zvivakwa. Mhando dzakawanda dzebleach ndeye chlorine bleach (sodium hypochlorite) uye oxygen bleach (hydrogen peroxide). Bleach inoshanda nekupwanya zvisungo zvemakemikari pakati pemavara uye pigment, zvinobudirira kubvisa ruvara kubva pazvinhu.
Misiyano Yakakosha Pakati peOptical Brighteners neBleach
1. Nzira yekuita:
-Optical Brightener: Inoita kuti zvinhu zviratidzike zvakachena uye kupenya nekutora UV maranzi uye kuaburitsa zvakare sechiedza chinooneka chebhuruu.
- Bleach: Inobvisa ruvara kubva kune zvinhu nekupwanya kemikari pasi mavara uye pigment.
2. Chinangwa:
- Fluorescent Whitening Agents: Inoshandiswa zvakanyanya kusimudzira kukwezva kwekuona kwezvinhu nekuita kuti zviratidzike zvakachena uye zvakanyanya kusimba.
- Bleach: Inoshandiswa kuchenesa, kuuraya utachiona uye kubvisa tsvina.
3. Application:
- Fluorescent Whitening Agent: Inowanzo shandiswa mumapurasitiki, machira uye detergents.
- Bleach: Inoshandiswa mudzimba dzekuchenesa zvigadzirwa, zvekugezesa mbatya uye maindasitiri ekuchenesa.
4. Kuumbwa Kwemakemikari:
- Fluorescent Whitening Agents: Kazhinji organic komisheni senge stilbene derivatives, coumarins uye benzoxazoles.
- Bleach: Inorganic makomisheni akadai sodium hypochlorite (chlorine bleach) kana organic komisheni senge hydrogen peroxide (oxygen bleach).
Chengetedzo uye Mafungiro Ezvakatipoteredza
Optical brightenersuye mabhureki ega ega ane chengetedzo yavo uye zvinonetsa kwezvakatipoteredza. Optical brighteners inowanzoonekwa yakachengeteka kuti ishandiswe muzvigadzirwa zvevatengi, asi pane kunetsekana nekushingirira kwavo munharaunda uye zvinogona kuitika pahupenyu hwemvura. Bleach, kunyanya chlorine bleach, inoparadza uye inogadzira zvinhu zvinokuvadza zvakadai se dioxins, izvo zvinokuvadza hutano hwevanhu uye nharaunda.
Mukupedzisa
Kunyangwe zvinopenya zvinopenya uye bleach zvingaratidzika zvakafanana nekuda kwekuchena kwavo mhedzisiro, maitiro avo, zvinangwa, uye mashandisirwo akasiyana zvakanyanya. Optical brighteners ndiwo akakosha makomisheni anoshandiswa kuwedzera kukwezva kwepurasitiki nezvimwe zvinhu nekuita kuti zviratidzike zvakachena uye nekupenya. Kusiyana neizvi, bleach ishambidzi ine simba inoshandiswa kubvisa tsvina nekuuraya utachiona panzvimbo.
Kunzwisisa mutsauko uyu kwakakosha kune vagadziri, vatengi, uye chero ani zvake anobatanidzwa mune zvekushandisa sainzi kana kugadzirwa kwechigadzirwa. Nekusarudza iyo komisheni yakakodzera yekushandisa kwayo, tinogona kuwana inodiwa inoyevedza uye inoshanda mhedzisiro tichidzikisa zvingangove zvakashata zvinokanganisa hutano uye nharaunda.
