Inā ʻoe i hele mai i kēia ʻaoʻao, ua kamaʻāina paha ʻoe i ke ʻano o nā kāmaʻa gumboots a me ka pono o nā kāmaʻa kiʻekiʻe a me ka wai.Akā, ua kū anei ʻoe e noʻonoʻo, he aha nā kāmaʻa ua? ʻAe, ʻo ka hapa nui o nā kāmaʻa wai i hana ʻia mai ka lāʻau kūlohelohe a i ʻole polyvinyl chloride - kahi mea synthetic i kapa ʻia ʻo PVC a i ʻole vinyl.
No loko mai o ka latex (sap) o ka laau kopa.Havea brasiliensis) ka mea e ulu ana ma ka honua holoʻokoʻa i nā biomes tropical e like me Brazil, Thailand, a me Indonesia.ʻO PVC, ma ka ʻaoʻao ʻē aʻe, he ʻano plastic i hana ʻia i loko o kahi lab a loaʻa mai ka ʻaila.Loaʻa nā pōmaikaʻi a me nā pōʻino i ka hana ʻana me kahi mea kūlohelohe a i ʻole kahi mea synthetic no ka mea e hāʻawi ana kēlā me kēia mea i kahi mea ʻokoʻa e pili ana i ka maikaʻi, ka lōʻihi, ke kaumaha, a me ka hiki.
ʻO ka mua, e kamaʻilio kākou e pili ana i ka lāʻau lapaʻau maoli!Hana ʻia nā kāmaʻa Merry People me ka lāʻau lapaʻau maoli i waho a me ka wāwae.No ka hoʻololi ʻia ʻana mai ka latex a lilo i ʻōpala (a laila i loko o kou gumboots), hele ka latex kūlohelohe i ka vulcanization, kahi hana i hoʻomohala ʻia a patent ʻia e Charles Goodyear o nā huila Goodyear.Hoʻomaʻamaʻa ka Vulcanization i ka ʻōpala a hiki ke hoʻoheheʻe ʻia i nā ʻano ʻē aʻe.Mai laila mai, ua hoʻolei ʻia i loko o nā ʻano pihi o nā kāmaʻa.He kaʻina hana lōʻihi kēia ma mua o nā ʻano hana i hoʻohana ʻia i ka hana ʻana i nā gumboots PVC, akā ʻo ka hopena ʻoi aku ka maikaʻi o ka insulation, palupalu, a me ka hana anti-corrosion.
ʻO ka lōʻihi, ka elasticity, a me ka maikaʻi o ka lāʻau lapaʻau maoli e hele mai me nā kālepa i ke kaumaha a me ke kumukūʻai.Ma muli o kona ʻano, ʻoi aku ke kaumaha o ka lāʻau ma mua o PVC, ʻo ia hoʻi, ʻoi aku ke kaumaha o nā gumboots kūlohelohe ma mua o ka PVC gumboots.ʻOi aku ke kumukūʻai o ka hana lima i ke kāʻili ʻana i ka latex mai ka lāʻau lapaʻau a me ka hana ʻana i ka lāʻau lapaʻau ma mua o ka hana ʻana i ka PVC.'O ia ho'i, 'oi aku ka nui o ke kumukū'ai o nā kāma'a pulupulu maoli ma mua o nā kāma'a PVC.Aia nō na'e, e hana 'ia ke kumu kū'ai ki'eki'e no ka lā'au pa'a maoli no ka lō'ihi o ke ola o ka mea no ka mea 'a'ole pono e ho'ololi pinepine 'ia kou mau kamaa.Manaʻoʻiʻo mākou i ka waiwai ma hope o ka lōʻihi a me ka loiloi ʻana i ke kumukūʻai-per-ʻaʻahu o kāu mau kāmaʻa kāmaʻa a ke kū nei mākou i kēia me kahi palapala hōʻoia hoʻokahi makahiki ma kā mākou mau kāmaʻa.
I kēia manawa e kamaʻilio e pili ana i ka PVC!ʻO PVC kahi ʻilika synthetic māmā i hana ʻia, ma kahi hapa, mai ka ʻaila.ʻO ka hana ʻana i ka PVC he kaʻina hana paʻakikī e pili ana i ka nui o ka kemika, akā he hana kaulana loa a maʻalahi hoʻi ia i hoʻohana ʻia ma nā ʻano ʻoihana ākea.No ka hoʻololi ʻana i ka PVC i mau kāmaʻa, hoʻoheheʻe ʻia nā pellet liʻiliʻi o PVC i loko o kahi ʻano wai, a laila ninini ʻia a puni kahi pahu pahu i kahi hana i kapa ʻia ʻo injection-moulding.Hoʻohana ʻia ka hoʻoheheʻe injection no nā ʻano papahana, e hana ana i kahi kaʻina hana maʻalahi no ka hana ʻana a hoʻolilo i nā kāmaʻa PVC i koho haʻahaʻa haʻahaʻa kaulana no ka wai wai a no ka poʻe e ʻimi nei i nā kāmaʻa māmā.
