ʻO Cork, kahi ʻano o ka cork, paʻakikī ke hoʻololi i nā piʻi kiʻekiʻe a me ka wela kiʻekiʻe a ulu ma nā mauna a me nā ululāʻau ma kahi kiʻekiʻe o 400-2000 mika ma nā ʻāpana subtropical a me ke anuanu. Hiki ke loaʻa nā kumu waiwai Cork ma nā wahi mauna i loko o ka laulā o 32 a 35 degere latitu ʻākau e kū pono ana i nā kūlana ʻāina a me ke anuanu. No ka laʻana, Pokukala, Sepania, hema o Farani, nā mauna ʻo Qinba i koʻu ʻāina, hema hema o Henan, a me Algeria. ʻO Pokukala ka mea kūʻai nui loa o ka cork ma ka honua a ua ʻike ʻia ʻo ia ʻo "Cork Kingdom" ma muli o kona ʻano ʻano ʻokoʻa Mediterranean, kahi kūpono no ka ulu ʻana o nā kumu kumu. Ma ka manawa like, ʻo Pokukala kekahi o nā ʻāina mua loa o ka honua e hoʻomohala i nā kumu waiwai cork, hoʻokuʻu aku i nā mea maka, a me nā huahana hana. ʻO ka hana ʻana o ka poʻo ʻo Algeria ma waena o ka poʻokela o ka honua. [2] Aia i loko o nā mauna ʻo Qinba ma ka ʻāina ʻo Shaanxi, koʻu ʻāina, nā kumu waiwai cork waiwai, ʻoi aku ma mua o 50% o nā kumu kumu cork o ka ʻāina. No laila, ʻike ʻia ʻo Shaanxi ʻo "Cork Capital" i ka ʻoihana. Ke hilinaʻi nei i kēia pono waiwai, ʻoi aku ka nui o nā mea hana cork home nui ma ʻaneʻi. Hoʻokumu ʻia ʻo Cork i nā pūnaewele pālahalaha he nui i hoʻonohonoho ʻia me ka radial. Loaʻa i ka lua o ke kelepona nā hui resin a me nā tannin, a ua piha nā keʻena i ka ea, no laila ke kala pinepine ka cork, māmā a palupalu, elastic, impermeable, ʻaʻole maʻalahi i nā kemika, a he mea hoʻokele maikaʻi ʻole o ka uila, wela a me ke kani. . Hoʻokumu ʻia ia me nā ʻāpana make ma ke ʻano he 14 mau maka, i hoʻonohonoho ʻia me ka radially i nā prisms hexagonal. ʻO ke anawaena pūnaewele maʻamau he 30 microns a ʻo ka mānoanoa cell he 1 a 2 microns. Aia nā auwai ma waena o nā pūnaewele. ʻO ka wā ma waena o ʻelua mau ʻāpana pili i haku ʻia he 5 papa, ʻelua o ia mea he fibrous, a ukali ʻia e ʻelua papa o ka cork, a me kahi papa lāʻau ma waenakonu. Aia ma mua o 50 miliona mau keneta i kēlā me kēia kenimika cubic.
