Nā Manaʻo Hoʻonā
Ka paʻa o ka mālamalama maikaʻi loa
ʻO ka ʻōlelo aʻoaʻo kūpono loa a ka hoʻoholo no ka huahana syntan
Aia mau kekahi mau ʻāpana kahiko a mākou e ʻike ai i ko mākou ola e hoʻohauʻoli ai iā mākou i kēlā me kēia manawa a mākou e noʻonoʻo ai iā lākou. E like me kēlā mau kāmaʻa ʻili keʻokeʻo ʻoluʻolu loa i loko o kou keʻena kāmaʻa.
Eia nō naʻe, hoʻonāukiuki iā ʻoe i kekahi manawa ke hoʻomanaʻo i ka hala ʻana o ka manawa, ʻaʻole e keʻokeʻo a ʻālohilohi hou kāu mau kāmaʻa punahele, a e lilo mālie a melemele.
I kēia manawa, e ʻike kākou i ke kumu o ka melemele ʻana o ka ʻili keʻokeʻo——
I ka makahiki 1911 AD, ua hoʻomohala ʻo Kauka Stiasny i kahi tannin synthetic hou e hiki ke pani i nā tannin mea kanu. I ka hoʻohālikelike ʻana me nā tannin mea kanu, maʻalahi ka hana ʻana i nā tannin synthetic, he waiwai tanning maikaʻi loa, he kala māmā a he komo maikaʻi. No laila ua lilo ia i kūlana koʻikoʻi i ka ʻoihana tanning i nā haneli makahiki o ka hoʻomohala ʻana. I ka ʻenehana tanning hou, hoʻohana ʻia kēia ʻano tannin synthetic ma aneane nā ʻatikala āpau.
Ma muli o kona ʻano like ʻole a me kāna noi, ua kapa pinepine ʻia lākou he synthetic tannin, phenolic tannin, sulfonic tannin, disperse tannin, etc. ʻO ka mea maʻamau o kēia mau tannins, ʻo ko lākou monomer he ʻano kemika phenolic.
Eia nō naʻe, ke hōʻike ʻia ka ʻano phenolic i ka lā, ʻoi aku hoʻi i nā kukuna UV, hana ia i kahi ʻano hana kala e hoʻolilo i ka ʻili i melemele: Hoʻololi maʻalahi ʻia ka ʻano phenol i loko o ka quinone a i ʻole ka p-quinone color-rendering structure, ʻo ia ke kumu he haʻahaʻa kona paʻa māmā.
Ke hoʻohālikelike ʻia me nā tannin synthetic, ʻoi aku ka maikaʻi o ka waiwai anti-yellowing o ka polymer tannin a me ka amino resin tanning agent, no laila i ka mālama ʻana i ka ʻili, ua lilo nā tannins synthetic i loulou nāwaliwali no ka hana anti-yellowing.
I mea e hoʻoponopono ai i kēia pilikia, ua hana ka hui R&D o Decision i kekahi mau hoʻomaikaʻi ʻana i ka ʻano phenolic ma o ka noʻonoʻo hou a me ka hoʻolālā ʻana, a ua hoʻomohala hope i kahi tannin synthetic hou me ka paʻa māmā maikaʻi loa:
ʻO DESOATEN SPS
ʻO Syntan me ka paʻa māmā maikaʻi loa
Ke hoʻohālikelike ʻia me nā syntans maʻamau, ua lele nui ka waiwai anti-yellowing o DESOATEN SPS——
ʻOiai ke hoʻohālikelike ʻia me ka mea hana tanning polymer maʻamau a me ka mea hana tanning amino resin, hiki iā DESOATEN SPS ke lanakila ma luna o lākou ma 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 ʻē aʻe a me nā fatliquors, hiki ke hoʻokō ʻia ka hana ʻana o ka ʻili maʻamau a me ka ʻili keʻokeʻo me ka paʻa ʻana o ka mālamalama maikaʻi loa.
No laila e hele a ʻaʻahu i kou mau kāmaʻa ʻili keʻokeʻo punahele e like me kou makemake, e hele ma ke kahakai a ʻauʻau i ka lā, ʻaʻohe mea e hiki ke pale iā ʻoe i kēia manawa!
Ua lilo ka hoʻomohala hoʻomau i mea nui loa i ka ʻoihana ʻili, akā ua lōʻihi ke ala i ka hoʻomohala hoʻomau a piha i nā pilikia.
Ma ke ʻano he ʻoihana kuleana, e hoʻokō mākou i kēia ma ke ʻano he kuleana a e hana mau me ka wiwo ʻole a hiki i ka pahuhopu hope loa.
E ʻimi hou aku
