Ka ikaika tensile: ʻike pū ʻia me ka ikaika tensile. E pili ana i ka ikaika i koi ʻia no kēlā me kēia ʻāpana no ka lāʻau e hoʻolōʻihi i kekahi lōʻihi, ʻo ia hoʻi, e hoʻolōʻihi i 100%, 200%, 300%, 500%. Hōʻike ʻia ma N/cm2. He hōʻailona mīkini koʻikoʻi kēia no ke ana ʻana i ka ikaika a me ka paʻakikī o ka lāʻau. ʻOi aku ka nui o kona waiwai, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o ka lāʻau, e hōʻike ana i kēia ʻano o ka lāʻau i liʻiliʻi i ka elastic deformation.
Kūʻē waimaka: Inā māwae nā huahana lāʻau lapaʻau i ka wā e hoʻohana ʻia ai, ʻoi aku ka nui o ka haehae ʻana a hiki i ka wā e ʻoki ʻia. No laila, ʻo ka pale ʻana i ka waimaka he hōʻailona hana mechanical nui no nā huahana lāʻau. ʻIke pinepine ʻia ke kūpaʻa waimaka e ka waiwai kūʻē waimaka, e pili ana i ka ikaika i koi ʻia no kēlā me kēia mānoanoa (cm) o ka lāʻau e haehae ai i ka ʻoki a hiki i ka haki ʻana, ana ʻia ma N/cm. ʻOiaʻiʻo, ʻoi aku ka nui o ka waiwai, ʻoi aku ka maikaʻi.
Adhesion a me ka ikaika pili: ʻO ka ikaika i koi ʻia e hoʻokaʻawale i nā ʻili hoʻopaʻa ʻelua o nā huahana lāʻau lapaʻau (e like me ke kāpili a me ka lole a i ʻole ka lole a me ka lole) i kapa ʻia ʻo adhesion. Hoʻohana pinepine ʻia ka nui o ka adhesion e ka ikaika adhesion, i hōʻike ʻia e like me ka ikaika o waho i koi ʻia no kēlā me kēia ʻāpana i ka wā e hoʻokaʻawale ʻia ai nā ʻāpana paʻa ʻelua o ka hāpana. ʻO ka helu helu N/cm a i ʻole N/2.5cm. ʻO ka ikaika adhesive kahi hōʻailona hana mechanical nui i nā huahana rubber i hana ʻia me ka pulupulu a i ʻole nā lole fiber ʻē aʻe e like me nā mea iwi iwi, a ʻoiaʻiʻo, ʻoi aku ka nui o ka waiwai, ʻoi aku ka maikaʻi.
ʻAʻahu poho: ʻike ʻia hoʻi he hōʻemi ʻaʻahu, ʻo ia ka hōʻailona koʻikoʻi nui no ke ana ʻana i ke kūpaʻa ʻana o nā mea lāʻau, a he nui nā ʻano no ke ana ʻana a me ka hōʻike ʻana. I kēia manawa, hoʻohana nui ʻo Kina i ke ʻano hoʻāʻo abrasion Akron, kahi e pili ana i ka friction ma waena o ka huila wili a me kahi huila wili paʻa paʻakikī (Shore 780) ma lalo o kahi kihi inclination (150) a me kahi ukana (2.72kg) e hoʻoholo ai i ka lole. ka nui o ka lāʻau lapaʻau i loko o kekahi hahau (1.61km), i hōʻike ʻia ma cm3/1.61km. ʻOi aku ka liʻiliʻi o kēia waiwai, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o ka lāʻau.
ʻO ka mahana wela a me ka mahana hoʻololi aniani: He mau hōʻailona maikaʻi kēia no ka hoʻoholo ʻana i ke kū anuanu o ka lāʻau. E hoʻomaka ka paʻakikī o ka Rubber ma lalo o ka zero degere Celsius i ka wā e ʻai ʻia ai, e hōʻemi nui ana i kona elasticity; Ke emi mau nei ka mahana, paʻa mālie a hiki i kahi e nalowale loa ai kona elasticity, e like me ke aniani, ʻeleʻele a paʻakikī, a hiki ke haki i ka hopena. Kapa ʻia kēia mahana ʻo ke aniani hoʻololi wela, ʻo ia ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa no ka lāʻau. Ma ka ʻoihana, ʻaʻole i ana ʻia ka mahana hoʻololi aniani (no ka lōʻihi o ka manawa), akā ke ana ʻia ka mahana brittle. ʻO ka mahana i hoʻomaka ai ka haʻihaʻi ʻana o ka lāʻau ma hope o ka maloʻo ʻana i ka haʻahaʻa haʻahaʻa no kekahi manawa a i hoʻokau ʻia i kekahi ikaika o waho i kapa ʻia ʻo ka brittle temperature. ʻOi aku ka kiʻekiʻe o ka mahana brittle ma mua o ka mahana hoʻololi aniani, a ʻo ka haʻahaʻa o ka mahana brittle, ʻoi aku ka maikaʻi o ke kū anuanu o kēia lāʻau.
Mahana māhā: Ma hope o ka hoʻomehanaʻiaʻana o ka lāʻau i kahi mahana, e pohā ka colloid, a ua kapaʻia kēia mahanaʻo ka mahana māhā. He hōʻailona hana kēia no ke ana ʻana i ka pale wela o ka lāʻau. ʻOi aku ka kiʻekiʻe o ka wela o ka pohā, ʻoi aku ka maikaʻi o ka pale wela o kēia ʻōpala. ʻO ka pae wela hana maoli o ka lāʻau lapaʻau maʻamau ma waena o ka wela haʻahaʻa a me ka mahana mahā.
Mea kūʻē i ka pehu: Hoʻopili pinepine ʻia kekahi mau huahana lāʻau lapaʻau me nā mea e like me ka waikawa, ka alkali, ka aila, a me nā mea ʻē aʻe i ka wā e hoʻohana ai, ka mea e hoʻonui ai i nā huahana lāʻau lapaʻau, lilo ka ʻili i mea paʻa, a ʻo ka hope e ʻoki ʻia nā huahana. ʻO ka hana ʻana o nā huahana rubber i ke kūʻē ʻana i nā hopena o ka waikawa, alkali, aila, etc. ʻElua mau ʻano no ke ana ʻana i ka pehu ʻana o ka lāʻau lapaʻau: ʻo ka hoʻoheheʻe ʻana i ka lapa i loko o kahi ʻano wai e like me ka waikawa, ka alkali, ka aila, etc. uku; ʻO ka liʻiliʻi o kona waiwai, ʻoi aku ka maikaʻi o ka pale ʻana o ka lāʻau i ka pehu. ʻO kekahi ala ʻē aʻe, ʻo ia ka hōʻike ʻana ma ka ratio o ka ikaika tensile ma hope o ka hoʻokomo ʻana i ka ikaika tensile ma mua o ka hoʻoinu ʻana, i kapa ʻia ʻo acid (alkali) resistance a i ʻole oil resistance coefficient; ʻO ka nui o kēia coefficient, ʻoi aku ka maikaʻi o ka pale ʻana o ka lāʻau i ka pehu.
Ka helu ʻelemakule: ʻO ke koena ʻelemakule he hōʻailona hana e ana i ke kūpaʻa ʻelemakule o ka lāʻau. Hōʻike ʻia ʻo ia ka ratio o nā waiwai kino a me nā mechanical (ikaika tensile a i ʻole ka huahana o ka ikaika tensile a me ka elongation) o ka lāʻau ma hope o ka ʻelemakule ma kahi mahana a no kekahi manawa. Hōʻike ka helu ʻelemakule kiʻekiʻe i ke kūpaʻa ʻelemakule maikaʻi o kēia lāʻau.
