E904 Kaʻa

Shellac (Shellac, E904) - aniani. ʻO ka resin kūlohelohe i hana ʻia e ka lacworm insect (Laccifer lacca), parasitic ma luna o kekahi mau lāʻau tropical a subtropical ma India a me ka Hikina Hema ʻo Asia (Croton laccifera a me nā mea ʻē aʻe).

Hoʻohana ʻia ʻo Shellac i ka hana ʻana i nā lacquers, nā mea hoʻīpī a me nā kiʻi paʻi kiʻi. Ma mua o ka hana ʻana o vinyl i 1938, ua hoʻohana ʻia ka shellac no ka hana ʻana i nā moʻolelo.

Shellac - pili kēia hua'ōlelo i ka hapanui o nā kānaka me ka hana manicure. ʻO ka ʻoiaʻiʻo, ʻo ka waiwai, ʻoiai e pili ana i nā mea hoʻonaninani hoʻonaninani no nā kui, ʻike ʻia ma lalo o ke code E904 i nā papa inoa honua o nā mea hoʻohui meaʻai, a pili i nā mea anti-flaming a me nā glazing i hoʻohana ʻia i ka ʻoihana meaʻai. ʻO ka ʻālohilohi i nā mea ʻono, nā dragees, nā lollipops, ke kokoleka a me nā huaʻai, ʻoi aku ka nui o kona ʻano i ka shellac meaʻai. ʻO nā inoa ʻē aʻe o ka additive he sticklak, gummilak resin a stocklak paha, a ʻo kekahi o nā mea maikaʻi i mahalo ʻia e nā mea hana meaʻai ʻo kona kumu maoli.

ʻO ka wehewehe ʻana o SHELLAC E904

ʻO Shellac E904 kahi resin amphora granular, nona nā ʻāpana o nā mea hoʻohui meaʻai: anti-flaming a me glazing agent. He kumu maoli maoli ka resin a ua ʻae ʻia. Hoʻohana ʻia ia ma ka ʻoihana meaʻai a me ka lāʻau lapaʻau, cosmetology a me ke kūkulu ʻana. ʻO nāʻaʻahu kiʻekiʻe me E904 ke kūpaʻa nui i ka lepo, ka lepo, nā'ōpala a me ka māmā. ʻO ke kala maoli o ka shellac e hāʻawi i nā lako i kahi nānā kahiko mōʻī.

Ke ala no ka loaʻa ʻana o Shellac E904

ʻO ka Shellac kahi hua ʻōpala o nā ilo. ʻO Thailand a me India ka noho ʻana o nā pepeke. Noho nā ilo ma luna o nā kumulāʻau a ʻai i ko lākou wai. Hoʻokuʻu ʻia ka mea hana hou ma o nā pores ʻili. ʻO kēia ka mea maka no ka loaʻaʻana o ka mea hoʻohui E904. Hiki ke hanaʻia nā mea waiwai, e pili ana i ka huahanaʻoihana hope loa. Hiki ke kūʻai ʻia ka resin ma ke ʻano maloʻo. He ʻili a i ʻole ka ʻiliʻili. He mea maʻamau nō hoʻi ka wai shellac. No ka loaʻa ʻana, hoʻoheheʻe ʻia ka resin i ka ethyl alcohol.

Nā waiwai o E904, nā hiʻohiʻona kemika a me nā hana hana

ʻO ka mea hoʻohui meaʻai Shellac e hōʻike ana i nā pūhui a me nā esters o nā mea momona a me nā momona hydroxy acids - aluretic, shellolic a me nā mea ʻē aʻe. Aia ka hui i nā lactones, pigments a me ka wax shellac. ʻO ka mea hana nui (resin) he 60-80% o ka mea hoʻohui E904.

Hoʻokomo pinepine ka mea i ka hana ma ke ʻano o nā flakes he mau millimeters wale nō ka mānoanoa. ʻAʻole hoʻoheheʻe ʻo Shellac i ka wai, nā momona, acetone a me nā ethers. Loaʻa iā ia ka solubility maikaʻi i ka alkalis, aliphatic alcohols, medium solubility i benzene, ethanol.

ʻO ka helu heheʻe o ka mea he 80 degere Celsius. Ma waho aʻe o ka pale wai, loaʻa nō hoʻi ke kūʻē i ka ʻike māmā, a me ka hopena insulating uila.

ʻO ka ʻōlelo mua o ka hoʻohana ʻana i kēia resin mai ka 1st millennium BC. ʻO India a me nā ʻāina o ka Hikina Hema ʻo Asia - kahi noho o nā iniseti i kapa ʻia ʻo Laccifer lacca (lacquer bugs), e like me nā bedbugs.

ʻAi kēia mau ʻōpala i ka resin kumulāʻau a me nā wai i huna ʻia mai nā lālā, ka ʻili a me nā lau o nā kumulāʻau. Ma muli o ke kaʻina hana hoʻoheheʻe ʻana o nā ilo, lilo nā meaʻai a lākou e ʻai ai i resin, i waiho ʻia e nā iniseti ma luna o nā lālā a me ka ʻili o nā lāʻau. Hoʻomaloʻo ka resin a i ʻole ka lacquer e hana i kahi ʻōpala i hōʻiliʻili ʻia no ka hana hou ʻana.

ʻO ka mea mua, ua hoʻoheheʻe ʻia ka mea maka me ka sodium carbonate - ma kēia ala e hoʻomaʻemaʻe ʻia ai ka shellac e hiki mai ana i nā ʻano mea haumia like ʻole (nā ʻōpala, nā lau).

Hoʻomaʻemaʻe ʻia ka mea i loaʻa me ka sodium hypochlorous acid a maloʻo.

No ka hoʻopau ʻana i ka wax i loko o ka additive, i ka hopena e kau ʻia i kahi hopena me kahi hopena nāwaliwali o ka sulfuric acid a ua kānana ʻia ka wax insoluble. ʻO ka hopena, loaʻa kahi shellac bleached i hoʻomaʻemaʻe ʻia mai ka wax.

Ma waho aʻe o nā kala keʻokeʻo, hiki ke ʻalani a ʻulaʻula paha. Hiki nō hoʻi ke synthesize i kahi mea hoʻohui kala ʻole.

ʻO ke kumu ʻenehana o ka mea hoʻohui E904 ka hoʻokumu ʻana i nā uhi aniani, ka pale ʻana a i ʻole ka hōʻemi ʻana i ka ikaika o ka hoʻokumu ʻana o ka foam, a me ka pale ʻana i ka hoʻopili ʻana o nā mea aniani i kekahi i kekahi.

Pehea e hoʻohana ʻia ai ka mea ma ka ʻoihana

I ka ʻoihana kemika, hoʻohana ʻia ʻo E904 e hana i nā pena, nā poli, nā varnish no nā mea kani lāʻau a me nā lako. Ma mua o ka hoʻokumu ʻana o vinyl i nā makahiki 40 o ke kenekulia i hala, ua hoʻohana ʻia ka ʻāpana i ke kaʻina hana o nā moʻolelo.

ʻO Shellac ke kumu no ka kiʻiʻoniʻoni polyethylene a me ka alumini alumini, hoʻohana ʻia i ka ʻoihana textile e hoʻopaʻa i ka manaʻo a me nā lole like, a he ʻāpana hoʻi ia o nā varnish insulating uila no ka impregnating coils o nā mea uila a me ka hana ʻana i nā ʻāpana uila.

ʻO Shellac kahi ʻāpana o nā lauoho lauoho a me nā shampoos, nā huahana styling lōʻihi lōʻihi, a me ka mascara wai.

ʻAʻole paʻa ka ʻoihana hoʻonaninani me ka ʻole o ka shellac: mahalo nui nā mea hana i kāna mau waiwai wai-repellent, ka paʻa o ka mahana a me ka hiki ke hana i ke ʻano pono o ka huahana.

Mai ka makahiki 2010, ua hoʻomaka ka hana nui o ka gel polish kūpaʻa i ʻAmelika Hui Pū ʻIa, nona ka additive E904, i kapa ʻia ʻo "Shellac". Hoʻokaʻawale ʻia ka uhi e kona ikaika kūikawā, saturation kala a me ka hiki ke pae i ka pā kui.

Hoʻohui pū ʻia i nā mea hoʻohui meaʻai a me nā pūpū pale wax no kekahi mau ʻano paʻakai.

Ma ke ʻano o kahi ʻāpana glazing a defoaming paha, loaʻa ʻo E904 i loko o ia mau meaʻai:

• nā hua hou (hua citrus, peaches, pears, apple, melons - no ka mālama ʻana i ka ʻili);
• nā meaʻono, nā lollipops, nā dragees, ke kokoleka;
• hua palaoa me ka hau;
• kofe palaoa;
• ʻūhū;
• nuipa marzipan.

Ma waho aʻe o ka hana ʻana i ka meaʻai, ua loaʻa pū ka shellac i kāna noi i ka ʻoihana lāʻau lapaʻau - ma ke ʻano he uhi aniani no kekahi mau lāʻau lapaʻau ma ke ʻano o nā papa a me nā dragees.

Hiki i ka shellac ke hoʻopilikia i ke olakino kanaka

ʻAʻohe pane maopopo e pili ana i ka hoʻohana ʻana i ka shellac i ka meaʻai i kēia lā.

Ua aʻo ʻia ka mea i loko o nā kūlana lab, a ʻaʻole i hoʻolaha ʻia ka ʻikepili kūhelu e pili ana i kona ʻona a i ʻole oncogenicity. ʻO ka pōʻino wale nō e hiki ke kau mai, ʻo ia ka maʻi maʻi.

I kekahi mau hihia o ka hoʻomanawanui ʻole o kēlā me kēia kanaka, nā meaʻai a me nā mea hoʻonaninani me kahi mea i loko o ka haku mele hiki ke hoʻoulu i ka ʻili a me ka ʻili ʻili.

ʻAʻole hoʻopili ʻia ka meaʻai E904 e ke kino ma kekahi ʻano a hoʻokuʻu ʻia mai ia mea me ka loli ʻole.

Nā rula o ka ʻeke a me ka mālama ʻana

Hiki ke lawe ʻia a mālama ʻia ʻo Shellac i loko o nā pahu like ʻole, no ka laʻana, jute a i ʻole nā ​​ʻeke lole synthetic (pono e ʻae ʻia nā mea no ka hoʻopili ʻana me nā huahana meaʻai), i loko o nā pahu lāʻau a i ʻole nā ​​pahu pahu, nā pahu, nā pahu.

Ma ke kūʻai kūʻai, loaʻa ka mea i loko o nā pahu foil a i ʻole i loko o ka pahu plastik.

Hoʻonohonoho ʻia ka E904 additive e ke kaiāulu honua ma ke ʻano he palekana. Ua ʻae ʻia kona hoʻohana ʻana ma nā mokuʻāina he nui: ma USA, Kanada, EU ʻāina, Russia. ʻO ke kokoleka kaulana ʻo Ritter sport i loko o kāna haku mele ʻana he shellac ma ke ʻano he mea aniani.

No ka mea he kumu maoli ka waiwai, he kakaikahi kona mau hoa paio: ma ka laulā, ʻo kona hoʻohana ʻana ma ke ʻano he ʻāpana o nā huahana meaʻai ʻaʻole ia e hoʻopaʻapaʻa.

Ke hoʻomau nei ka noiʻi ʻana i nā hopena o ka shellac i ke olakino kanaka i kēia lā, akā i kēia manawa ke hōʻike nei nā haʻawina āpau ʻaʻole pono ka meaʻai E904, akā ʻaʻole ia e hōʻeha i ke kino.
