ʻO ka palaki o ka lāʻau

ʻO ka hiki i ka lāʻau ke hoʻololi i lalo o nā ikaika o waho a mālama i kona deformation ʻoiai ma hope o ka hoʻopau ʻia ʻana o nā mana o waho i kapa ʻia he plasticity.ʻO ke kaʻina hana o ka hoʻonui ʻana i ka plasticity i kapa ʻia ʻo plasticization.He plasticity ka Rubber i mea e hui like ai me nā mea hoʻohui like ʻole i ka wā e hui ai;E maʻalahi e komo i loko o nā lole lole i ka wā o ka ʻōwili ʻana;Loaʻa ka wai maikaʻi i ka wā extrusion a me ka injection.Eia kekahi, hiki i ka hoʻoheheʻe ʻana ke hana i nā waiwai o ka ʻaʻahu rubber, e maʻalahi ke kāohi i ke kaʻina hana.Eia nō naʻe, hiki i ka hoʻololi hoʻololi ke hōʻemi i ka ikaika, elasticity, pale ʻana a me nā waiwai ʻē aʻe o ka vulcanized rubber, no laila pono e hoʻomalu pono ʻia ka hana hoʻoheheʻe.
He kūpono ke koi ʻana o ka palaka maka, a ʻo ka nui a i ʻole ka liʻiliʻi hiki ke loaʻa nā hopena ʻino.Hiki ke hoʻemi i ka waiwai kino a me ka mechanical o ka rubber vulcanized i ka nui o ka palaka maka, e pili ana i ka hoʻohana ʻana o ka huahana.Inā haʻahaʻa loa ka plasticity o ka lāʻau maka, e pilikia ia i ka hana ʻana a paʻakikī i ka hui like ʻana o ka mea hao;ʻO ka ʻōwili, ʻaʻole maʻalahi ka ʻili o ka huahana semi-finished i ke kaomi ʻana i waho;ʻO ka hoʻopaʻi hōʻemi nui he mea paʻakikī ke hopu i ka nui o nā huahana semi-hoʻopau;I ka wā o ka ʻōwili ʻana, he mea paʻakikī i ka lipine adhesive e hamo i loko o ka lole, e ʻohi ai i ka lole kaula e kau ana a hoʻemi nui i ka hoʻopili ʻana ma waena o nā papa mea.Inā ʻaʻohe kūlike ka plasticity, hiki nō ke hoʻohālikelike i nā ʻano ʻenehana a me ke kino o ka adhesive.
No laila, loaʻa i ka ʻenehana hoʻoheheʻe ʻana i kekahi mau koi no ka plasticity o ka rubber raw.ʻO ka ʻōlelo maʻamau, ʻo nā mea hoʻopili i hoʻohana ʻia no ka uhi ʻana, ke kuʻi ʻana, ka ʻoki ʻana, a me ka hana ʻana i nā mea hoʻopili sponge e koi i ka plasticity kiʻekiʻe;ʻO nā mea Rubber a me nā mea hoʻoheheʻe ʻia e pono ai ke kiʻekiʻe kiʻekiʻe o ke kino a me ka mechanical a me ka ʻoʻoleʻa maikaʻi o nā huahana semi-finished he haʻahaʻa haʻahaʻa;ʻO ka plasticity o ka extruded adhesive ma waena o nā mea ʻelua.
