Eia nō naʻe, ke ʻike ʻia ka hale phenolic i ka lā, ʻoi aku hoʻi i nā kukuna UV, hana ia i kahi ʻano hana kala e hoʻohuli ai i ka ʻili melemele: ʻO ke ʻano o ka phenol ua maʻalahi i ka oxidized i ka quinone a i ʻole ka p-quinone color-rendering structure, ʻo ia ke kumu. He ʻilihune kona māmā māmā.
Ke hoʻohālikelike nei i ka tannin synthetic, polymer tannin agent a me amino resin tanning agent i ʻoi aku ka maikaʻi o ka waiwai anti-yellowing, no laila i ka mālama ʻana i ka ʻili, ua lilo nā tannin synthetic i mea nāwaliwali no ka hana anti-yellowing.
I mea e hoʻoponopono ai i kēia pilikia, ua hana ka hui R&D o Decision i ka hoʻonui ʻana i ka hoʻolālā phenolic ma o ka noʻonoʻo a me ka hoʻolālā ʻana, a ua hoʻomohala i kahi tannin synthetic hou me ka wikiwiki māmā maikaʻi loa:
DESOATEN SPS
ʻO Syntan me ka wikiwiki māmā maikaʻi loa
I ka hoʻohālikelike ʻana i nā syntans maʻamau, ua lele nui ka waiwai anti-yellowing o DESOATEN SPS——
ʻOiai ke hoʻohālikelike ʻana me ka mea hana tanning polymer maʻamau a me ka amino resin tanning agent, hiki iā DESOATEN SPS ke hoʻopau iā lākou i kekahi mau ʻano.
Ma ka hoʻohana ʻana iā DESOATEN SPS ma ke ʻano he tannin synthetic nui, i hui pū ʻia me nā mea tanning a me nā momona momona, hiki ke hoʻokō ʻia ka hana ʻana o ka ʻili maʻamau a me ka ʻili keʻokeʻo me ka wikiwiki māmā maikaʻi loa.
No laila e hele a ʻaʻahu i kāu mau kāmaʻa ʻili keʻokeʻo punahele e like me kou makemake, e hele ma kahakai a ʻauʻau i ka lā, ʻaʻohe mea hiki ke hoʻōki iā ʻoe i kēia manawa!
Ma ke ʻano he ʻoihana koʻikoʻi, e lawe mākou i kēia ma ke ʻano he kuleana a me ka hana hoʻomau a paʻa i ka pahuhopu hope.
