ʻO ka Rubber, kahi mea waiwai nui i nā ʻoihana hou, ua hoʻokaʻawale ʻia i ʻelua ʻano: ka lāʻau kūlohelohe a me ka ʻōpala synthetic. Hāʻawi kēia mau ʻokoʻa ʻelua i kahi ākea o nā noi, mai nā kaʻa kaʻa a hiki i nā mea lapaʻau, ma muli o kā lākou mau waiwai kūʻokoʻa. He mea koʻikoʻi ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o ka lāʻau kūlohelohe a me ka synthetic no ke koho ʻana i nā mea kūpono no nā noi kikoʻī.
ʻO ka piʻi ʻana o Ua hoʻololi ka lāʻau synthetic i nā ʻoihana ma o ka hāʻawi ʻana i nā mea ʻē aʻe i ka lāʻau kūlohelohe, ʻoi loa i nā kūlana i ʻike ʻia nā palena o ka lāʻau kūlohelohe, e like me ka hiki ke ʻelemakule a me nā kūlana kaiapuni. Hoʻopili kēia ʻatikala i nā ʻokoʻa ma waena o kēia mau ʻano lāʻau lapaʻau ʻelua, e ʻimi ana i ko lākou kumu, nā waiwai, nā noi, a me nā hopena o ke kaiapuni.
ʻO ka Rubber Natural: Nā kumu a me nā waiwai
Ke Kumu o ka Rubber Natural
Loaʻa ʻia ka lāʻau lapaʻau maoli mai ka latex o nā lāʻau lapaʻau, ʻo ia hoʻi ʻo Hevea brasiliensis. He wai waiu kēia latex e hana ana i nā kaʻina hana, e like me ka coagulation a me ka maloʻo ʻana, e hana ai i ka ʻōpala maka. Hoʻokumu ʻia ka mahi ʻana i nā lāʻau lapaʻau ma nā ʻāina wela, me nā ʻāina e like me Thailand, Indonesia, a me Malaysia ka mea hana nui loa.
Na Waiwai o ka Lapa Maoli
Kaulana ʻia ka lāʻau kūlohelohe no kona elasticity maikaʻi loa, ka ikaika tensile kiʻekiʻe, a me ke kūpaʻa ʻana i ka lole a me ka waimaka. Hōʻike pū ia i nā waiwai insulation uila maikaʻi a hana maikaʻi i nā kaiapuni haʻahaʻa haʻahaʻa. Eia nō naʻe, loaʻa nā palena, e like me ke kūpaʻa maikaʻi ʻole i ka wela, ka māmā, a me ka ozone, hiki ke alakaʻi i ka hoʻohaʻahaʻa ʻana i ka manawa.
ʻO ka Rubber Synthetic: He Hana Hou
Hoʻomohala ʻana i ka Rubber Synthetic
Ua hoʻomohala ʻia ka synthetic rubber ma ke ʻano he pane i nā palena o ka lāʻau kūlohelohe a me ka pono o kahi mea ʻoi aku ka maʻalahi. Ua hana ʻia ka ʻōpala synthetic mua, i kapa ʻia ʻo Buna, i ka hoʻomaka ʻana o ke kenekulia 20. Mai ia manawa mai, ua alakaʻi ka holomua i ka kemika polymer i ka hoʻomohala ʻana i nā ʻano ʻano ʻano like ʻole o ka ʻōpala synthetic, me ka styrene-butadiene rubber (SBR), nitrile rubber (NBR), a me ka ethylene-propylene-diene monomer (EPDM).
Pono o ka Rubber Synthetic
Hāʻawi ka synthetic rubber i nā mea maikaʻi ma mua o ka lāʻau kūlohelohe, e like me ka hoʻomaikaʻi ʻana i ka pale ʻana i ka wela, nā kemika, a me ka ʻelemakule. Hiki ke hoʻolikelike ʻia e hoʻokō i nā koi kikoʻī ma o ka hoʻololi ʻana i kona haku melemele. No ka laʻana, kūpaʻa nui ʻo EPDM i ka wā a me ka ozone, e kūpono ana ia no nā noi waho, ʻoiai ʻike ʻia ʻo NBR no kāna kūpaʻa aila maikaʻi loa.
Nānā Hoʻohālikelike: Natural vs. Synthetic Rubber
Hana ma nā ʻano noi like ʻole
Hoʻohana nui ʻia ka lāʻau kūlohelohe i nā noi e koi ana i ka elasticity kiʻekiʻe a me ka ikaika tensile, e like me nā kaʻa kaʻa, nā kāʻei conveyor, a me nā kāmaʻa. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi o ka lāʻau synthetic i nā kaiapuni kahi koʻikoʻi ke kūʻē ʻana i nā wela wela, nā kemika, a i ʻole ka ʻelemakule. No ka laʻana, hoʻohana maʻamau ʻia ka SBR i nā kaʻa kaʻa, ʻoiai ke hoʻohana ʻia ka silicone rubber i nā lāʻau lapaʻau a me nā sila.
Ka hopena o ke kaiapuni
ʻO ka hana ʻana i ka lāʻau lapaʻau maoli kahi kapuaʻi kaiapuni koʻikoʻi ma muli o ka hoʻopau ʻana i ka ululāʻau a me ka hoʻohana ʻana i nā kemika i nā mahi kanu lāʻau. ʻO ka rubber synthetic, ʻoiai e hōʻemi ana i ka hilinaʻi ʻana i nā kumuwaiwai kūlohelohe, loaʻa mai nā huahana i hoʻokumu ʻia i ka ʻaila, e hāpai ana i nā hopohopo e pili ana i ka hoʻokuʻu kalapona a me ka biodegradability ʻole. Ke hoʻoikaika ʻia nei ka hoʻomohala ʻana i nā mea ʻokoʻa hoʻomau, e like me ka bio-based synthetic rubber.
Ka hopena
I ka hopena, ʻo ka koho ma waena o ka rubber kūlohelohe a me ka synthetic e pili ana i nā koi kikoʻī o ka noi. ʻOiai ʻoi aku ka maikaʻi o ka lāʻau kūlohelohe i ka elasticity a me ka ikaika tensile, hāʻawi ka lāʻau syntka ikaika tensile, hāʻawi ka lāʻau synthetic i ke kūʻē ʻoi aku i nā mea kūlohelohe a me nā mea kemika. Ke hoʻomau nei ka holomua ʻana o ka ʻenehana rubber i ka hoʻonui ʻana i nā hiki no nā ʻano ʻelua o ka lāʻau lapaʻau, e hōʻoia ana i ko lākou pili i nā ʻoihana like ʻole.
No ka poʻe hoihoi i ka ʻimi ʻana i nā ʻano like ʻole o ka synthetic rubber a me kā lākou noi, e kipa synthetic rubber no ka ʻike kikoʻī.
