Nā kumu o ka melemele ʻana o nā lole
1.Photo melemele
ʻO ka melemele kiʻi e pili ana i ka melemele ʻana o ka ʻili o nā lole lole i hana ʻia e ka molecular oxidation cracking reaction ma muli o ka lā a i ʻole ke kukui ultraviolet.ʻO ka melemele kiʻi ka mea maʻamau i nā lole kala māmā, nā lole bleaching a me nā lole keʻokeʻo.Ma hope o ka ʻike ʻia ʻana o ka lole i ka mālamalama, hoʻololi ʻia ka ikehu māmā i kalole loleka waihoʻoluʻu, ka hopena i ka nahae ʻana o nā kino i hui pū ʻia a laila e mae ka māmā a me ka melemele o ka ʻili.Ma waena o lākou, ʻo ke kukui ʻike ʻia a me ke kukui ultraviolet nā kumu nui e hoʻopau ai i nā dyes azo a me nā phthalocyanine dyes.
2.Phenolic melemele
ʻO ka melemele Phenolic ma ke ʻano maʻamau, ʻo ia ka NOX a me nā pūhui phenolic e hoʻopili a hoʻololi a hoʻoulu i ka melemele o ka ʻili lole.ʻO ka mea nui reactive ka mea maʻamau i nā antioxidants i loko o ka mea hoʻopili, e like me ka butyl phenol (BHT).Ma hope o ka haʻalele ʻana i ka hale hana, e noho ka lole a me nā kāmaʻa ma lalo o ka manawa lōʻihi o ka hoʻopili ʻana a me ka lawe ʻana.No laila, e pane ka BHT i loko o ka mea hoʻopili me NOX i ka lewa, e alakaʻi ana i ka melemele.
3.Oxidation melemele
ʻO ka melemele oxidation e pili ana i ka melemele ma muli o ka hoʻoheheʻe ʻia o nā lole e ka lewa a i ʻole nā mea ʻē aʻe.Hoʻohana pinepine ʻia nā lole lole lole i nā mea pena hoʻoheheʻe a i ʻolemau kokuai ke kala a me ka hoopau ana.Ma hope o ko lākou hoʻopili ʻana me nā kinoea oxidizing, loaʻa ka hoʻemi ʻana o ka oxidation a me ka melemele.
4.Whitening agent yellowing
ʻO ka melemele ʻana o ka mea hana keʻokeʻo ma luna o nā lole kala māmā.Ke neʻe nei ke koena whitening agent ma ka ʻili lole ma muli o ka mālama ʻana i ka wā lōʻihi, e alakaʻi ia i ka excessive local whitening agent a me nā lole melemele.
5. Softening agent yellowing
ʻO nā ion cationic i loko o nā mea kōkua palupalu i hoʻohana ʻia i ka hoʻopau ʻana i ke kaʻina hana e hoʻoheheʻe ʻia i ka wā e kau ʻia ai ka wela, ka māmā a me nā kūlana ʻē aʻe.ʻO ia ka hopena o ka melemele o nā ʻāpana palupalu o ka lole.
ʻOiai ua māhele ʻia ka melemele i nā ʻano ʻelima i ʻōlelo ʻia ma luna nei, i ka hoʻohana maoli ʻana, ʻo ke ʻano melemele ʻaʻahu ke kumu ma muli o nā kumu like ʻole.
Pehea e pale ai i ka melemele o nā lole?
1. Ma ke kaʻina hana, pono e ho'āʻo nā ʻoihana e hōʻemi i ka hoʻohana ʻana i ka mea keʻokeʻo keʻokeʻo, haʻahaʻa ma mua o ka maʻamau yellowing agent.
2.I ka hoʻonohonoho i ka hoʻopau ʻana i ke kaʻina hana, ʻaʻole kiʻekiʻe ka mahana.ʻO ka wela kiʻekiʻe e hoʻoheheʻe ʻia nā mea pena a i ʻole nā mea kōkua ma ka ʻili o ka lole, a laila e melemele ka lole.
3.Ma ke kaʻina o ka hoʻopili ʻana, ka mālama ʻana a me ka lawe ʻana, pono e hoʻohana i nā mea hoʻopihapiha me ka BHT haʻahaʻa.A pono e mālama ʻia ka mālama ʻana a me ka halihali ʻana i ka mahana maʻamau a me ka ventila e like me ka hiki ke pale i ka melemele phenolic.
4. I ka hihia o ka phenolic yellowing o ka lole lole ma muli o ka hoʻopili ʻana, i mea e hōʻemi ai i nā poho, hiki ke hoʻopuehu ʻia kahi nui o ka pauka hōʻemi ma lalo o ka pahu a hoʻopaʻa ʻia ka pahu pahu no 1 a 2 mau lā, a laila wehe ʻia. a waiho ʻia no 6 mau hola.Ma hope o ka pau ʻana o ke ʻala, kalole lolehiki ke hoʻopaʻa hou ʻia.No laila hiki ke hoʻoponopono ʻia ka melemele i ka nui loa.
5. I ka hoʻohana ʻana i kēlā me kēia lā, pono nā kānaka e hoʻolohe i ka mālama ʻana, holoi pinepine a me ka mālie a pale i ka hōʻike lōʻihi.
