ʻO I. Rubber's "Dual Identity": ʻO ka pāʻani ma waena o ka Natural and Synthetic Rubber ʻaʻole ia he mea hoʻokahi, akā he huaʻōlelo maʻamau no nā ʻōnaehana nui ʻelua: ka lāʻau kūlohelohe a me ka lāʻau synthetic. Loaʻa i kēlā me kēia me kona pono ponoʻī a hui pū i nā pono o nā hiʻohiʻona like ʻole. Loaʻa ka lāʻau kūlohelohe mai ka wai keʻokeʻo keʻokeʻo o nā kumulāʻau lāʻau lapaʻau, i hana ʻia ma o ka coagulation, maloʻo, calendering a me nā hana ʻē aʻe. Loaʻa iā ia ka ultra-elasticity kiʻekiʻe (elongation rate a hiki i 1000%), maikaʻi loa ke pale ʻana i ka ʻaʻahu a me ka waimaka, e lilo ana ia i mea maka kūpono no nā mea nui e like me nā kaila a me nā sila. Eia nō naʻe, pili nui ka hana o ka lāʻau lapaʻau maoli e ke aniau a me ke kumu, a ʻaʻole lawa kona kūpaʻa i nā kaiapuni kiʻekiʻe a me ka ʻaila. He "huahana ʻenehana" o ka makahiki ʻenehana, hana ʻia mai ka ʻaila a me ke kinoea maoli me ka hana maʻamau ma o ka ʻenehana synthesis kemika. No ka laʻana, hoʻohana pinepine ʻia ka ʻaila nitrile pale i nā sila mechanical, hiki ke hoʻohana ʻia ka lāʻau silicone kūpaʻa kiʻekiʻe i mau mea hoʻopaʻa aerospace, a ua kūpono ka neoprene kū i ke anuanu no nā lako polar. Hoʻopili ka synthetic rubber i nā hemahema o ka lāʻau kūlohelohe a ua lilo i "mea pono" i nā wahi kūikawā.
II. "Elastic Magic" i ke Ola: Ua hoʻohui lōʻihi ʻia ka Daily Penetration of Rubber Products Rubber i nā kikoʻī āpau o ke ola, me ka hoʻohana ʻana i ka ʻenehana e hoʻonui ai i ka hōʻoluʻolu a me ka palekana. Hana ʻia nā kapuaʻi kāmaʻa haʻuki me ka pulupulu, e loaʻa ana nā pōmaikaʻi ʻelua o "lightweight + cushioning" ma o ka hoʻolālā microporous structure -hiki iā lākou ke komo ma mua o 80% o ka ikaika o ka honua i ka wā e hele ai, me ka pale pono ʻana i nā hui. ʻO nā meaʻai -ʻano kīhini silicone i loko o ka lumi kuke hiki ke kū i nā mahana a hiki i 230 degere, ʻaʻole hiki ke hoʻopili pololei i ka meaʻai akā ke pale aku i ka haumia aila, ʻaʻohe koena ma hope o ka hoʻomaʻemaʻe ʻana, a ua lilo i mea pono -no ka kuke ʻana. Ma nā hi'ohi'ona home, ho'oponopono mālie nā mea ho'opale e like me-pu'u puka 'ole, nā pani puka hāmau, a me nā moena papa ha'alulu e ho'oholo mālie i ka hakakā a me ka wala'au o ke ola; ʻO nā ʻāpana ʻeleʻele palupalu i nā mea pāʻani a nā keiki e hāʻawi i ka palapala hōʻoia ʻona ʻole e hōʻoia i ka palekana o nā keiki ke pāʻani; ʻo nā puka pepeiao o nā pale maka a mākou e hoʻohana mau nei, ua hana ʻia me ka ʻili -elasticity kiʻekiʻe, kūpono ke kaulike a me ka ʻoluʻolu.
III. "Hardcore Pillar" i loko o ka ʻenehana a me ka ʻenehana I loko o ka ʻoihana a me ka hana kiʻekiʻe -hopena, ʻoi aku ka paʻakikī o nā koi hana no nā huahana lāʻau lapaʻau, e lilo lākou i kākoʻo koʻikoʻi no nā holomua ʻenehana. ʻO nā kaʻa kaʻa he hōʻailona maʻamau o nā noi lāʻau: i haku ʻia me ka lāʻau kūlohelohe, ka lāʻau synthetic, ke kalapona ʻeleʻele, ka sulfur a me nā mea ʻē aʻe, ma hope o ka mālama ʻana i ka vulcanization, loaʻa iā lākou ke kūpaʻa ʻelua, ke kūpaʻa ʻelemakule a me ka paʻa. Hiki i ke kaila ki'eki'e-ke kū'ē i nā mahana wela loa mai -40 degere a 70 degere, me ke ola lawelawe 'oi aku ma mua o 80,000 kilomika. Ma ke kahua aerospace, ʻo nā ʻāpana lāʻau i hoʻopaʻa ʻia ka "pale palekana" o ka mokulele. Hiki i nā sila i hana ʻia me ka lāʻau synthetic kūikawā ke hoʻopaʻa i ka paʻa i loko o kahi ʻokoʻa ʻokoʻa o ka mahana o -50 degere a 200 degere, kū i ka hopena o ke kinoea kiʻekiʻe me ka leakage, a hōʻoia i ka hana paʻa o ka mokulele. He koi kiʻekiʻe loa ka ʻoihana lapaʻau no ka sterility a me ka hoʻohālikelike ʻana o nā huahana rubber. Hana ʻia nā mīkina lima lāʻau lapaʻau i ka lāʻau maʻemaʻe maʻemaʻe kiʻekiʻe, ma hope o ka sterilization ʻaʻole hiki ke hoʻokaʻawale wale i ka bacteria a me nā maʻi maʻi akā e hōʻoiaʻiʻo i ka maʻalahi o nā hana a nā limahana lapaʻau; ʻO nā paipu lāʻau lapaʻau i hoʻohana ʻia no ka lawe ʻana i ka lāʻau lapaʻau he kūpaʻa ka corrosion, pale i nā hopena ma waena o nā mea lāʻau a me ka lāʻau lapaʻau, a me ka mālama ʻana i ka palekana o ka lāʻau.
IV. Nā ʻano o ka wā e hiki mai ana: Hoʻomaikaʻi ʻelua o ka mālama ʻana i ke kaiapuni a me ka naʻauao Me ka holomua o ka ʻenehana, ke hoʻolalelale nei nā huahana rubber i ka hoʻololi ʻana i ka mālama kaiapuni a me ka naʻauao. Ma ke ʻano o ka mālama ʻana i ke kaiapuni, ua lilo nā mea hoʻoheheʻe ʻia i wahi wela noiʻi. Hiki ke hoʻoheheʻe ʻia ia mau mea e nā microorganism i loko o ke kaiapuni kūlohelohe, me ka hoʻoponopono maikaʻi ʻana i ka pilikia kaiapuni i paʻakikī ke hoʻohana hou ʻia. I kēia manawa, ua hoʻohana ʻia ka lāʻau hoʻoheheʻe ʻia i ka papa ʻaina hoʻopau ʻia, nā kiʻi ʻoniʻoni mulch mahiʻai a me nā huahana ʻē aʻe, a ke manaʻo ʻia nei e hoʻololi i nā huahana lāʻau kuʻuna i ka wā e hiki mai ana. Ua wehe ka puka ʻana mai o ka rubber smart i kahi ala hou. Ma ka hoʻokomo ʻana i nā mea ʻike i loko o ka lāʻau, hiki ke loaʻa ka nānā ʻana -manawa maoli i ke kaomi, ka mahana, ka hoʻololi ʻana a me nā ʻikepili ʻē aʻe. Eia kekahi laʻana, hiki i nā kāmaʻa kāmaʻa akamai ke hoʻopaʻa i ka hele wāwae, hāʻawi i ke kākoʻo ʻikepili no ka hoʻokele olakino; Hiki ke nānā i ke kūlana o ka hana ʻana o nā mea hana a me ka ʻōlelo mua ʻana i nā pilikia hemahema.
Mai nā mea e pono ai i kēlā me kēia lā a hiki i ka -ʻenehana ʻenehana hou loa, kākau nā huahana lāʻau i nā moʻolelo hou me ka elasticity a me ka paʻakikī. I ka wā e hiki mai ana, me ka holomua o ka ʻenehana waiwai, e alohilohi kēia "pōhaku kihi ʻike ʻole" i nā kula hou aʻe a hoʻomau i ka hoʻololi ʻana i ko mākou ola.
