1. Ke kahe kaʻina hana kumu
Nui nā ʻano o nā huahana lāʻau lapaʻau, akā ʻo ke kaʻina hana i ke kumu like.ʻO ke kaʻina hana maʻamau o nā huahana lāʻau lapaʻau me ka paʻa paʻa paʻa-raw rubber ma ke ʻano he ʻano kumu ʻeono: plasticizing, mixing, calendering, extrusion, molding and vulcanization.ʻOiaʻiʻo, pono ʻole nā kaʻina hana maʻamau e like me ka hoʻomākaukau ʻana i ka maka, ka hoʻopau ʻana i ka huahana, ka nānā ʻana a me ka hoʻopili ʻana.ʻO ka ʻenehana kaʻina hana o ka lāʻau ka mea nui e hoʻoponopono i ka kuee ma waena o ka plasticity a me nā waiwai elastic.Ma o nā ʻano ʻenehana like ʻole, ua hoʻololi ʻia ka lāʻau elastic i ka plastic masticated rubber, a laila hoʻohui ʻia nā mea hoʻohui like ʻole e hana i nā huahana semi-finished, a laila hoʻohuli ʻia nā huahana semi-finished plastic i nā huahana rubber me ka elasticity kiʻekiʻe a me ke kino a me ka mīkini maikaʻi. waiwai ma o ka vulcanization.
2. Hoʻomākaukau mea maka
ʻO ka mea waiwai nui o nā huahana lāʻau lapaʻau, ʻo ia ke kumu kumu, a ʻohi ʻia ka lāʻau maka ma ke ʻoki ʻana i ka ʻili o nā kumulāʻau lāʻau i ulu ʻia ma nā ʻāina ākea a me nā subtropics.
ʻO nā mea hoʻohui like ʻole he mau mea kōkua i hoʻohui ʻia e hoʻomaikaʻi i kekahi mau waiwai o nā huahana lāʻau.
Hoʻohana ʻia nā mea fiber (ka pulupulu, ka hemp, ka hulu hipa a me nā mea like ʻole i hana ʻia e ke kanaka, nā fiber synthetic a me nā mea metala, nā uea kila) i hoʻohana ʻia e like me nā mea iwi iwi no nā huahana lāʻau e hoʻoikaika ai i ka ikaika mechanical a kaupalena i ka deformation huahana.I ke kaʻina o ka hoʻomākaukau ʻana i nā mea maka, pono ke kaupaona pono ʻia nā mea e like me ke ʻano.I mea e hui like ai ka ʻōpala maka a me ka mea hoʻohuihui me kekahi, pono e hana ʻia ka mea.Pono e hoʻopalupalu ʻia ka ʻōpala maka i loko o kahi lumi hoʻomaloʻo ma 60-70 ℃, a laila ʻoki a ʻoki ʻia i ʻāpana liʻiliʻi.He puʻupuʻu ka mea hoʻohuihui.E like me ka paraffin, stearic acid, rosin, etc.Inā loaʻa i ka pauka nā mea haumia mechanical a i ʻole nā mea ʻāpana koʻikoʻi, pono e hoʻopaʻa ʻia e wehe i nā wai e like me ka pine tar a me ka coumaron, pono e hoʻomehana ʻia, hoʻoheheʻe ʻia, evaporated, a kānana.ʻO ka hoʻokumu ʻana o ka pōpō i ka wā o ka vulcanization like e pili ana i ka maikaʻi o ka huahana.
3. Hoʻopalekana
He elastic a nele ka plasticity e pono ai no ka hana ʻana, no laila ʻaʻole maʻalahi ke hana.I mea e hoʻomaikaʻi ai i kona plasticity, pono ia e masticate i ka ʻōpala maka, i hiki ke maʻalahi a hoʻopuehu ʻia ka mea hoʻohuihui i ka ʻōpala maka i ka wā e hui pū ai, a i ka manawa like, he mea kōkua nō hoʻi e hoʻomaikaʻi i ka permeability o ka. ka lāʻau a komo i loko o ka lole fiber i ka wā o ka calendering a me ka hana ʻana.a me ka hoʻoheheʻe ʻana i ka wai.ʻO ke kaʻina hana o ka hoʻohaʻahaʻa ʻana i nā molekole kaulahao lōʻihi o ka ʻōpala maka e hana i ka plasticity i kapa ʻia ʻo mastication.ʻElua mau ala o ka plasticizing raw rubber: mechanical plasticizing a me thermal plasticizing.ʻO ka mīkini mastication kahi kaʻina e hoʻohaʻahaʻa ʻia ai nā molekala hao kaulahao lōʻihi a pōkole mai kahi kūlana elastic kiʻekiʻe a i kahi kūlana plastik ma o ka hoʻokuʻu ʻana a me ka friction o ka plasticizer ma kahi haʻahaʻa haʻahaʻa.ʻO ka plasticizing wela ka hoʻoheheʻe ʻana i ka ea i hoʻopaʻa ʻia i loko o ka ʻōpala maka ma lalo o ka hana o ka wela a me ka oxygen e hoʻohaʻahaʻa ai i nā molekole kaulahao lōʻihi a pōkole iā lākou e loaʻa ai ka plasticity.
4. Ka hui 'ana
I mea e hoʻololi ai i nā ʻano like ʻole o ka hoʻohana ʻana, loaʻa nā waiwai like ʻole, a i mea e hoʻomaikaʻi ai i ka hana o nā huahana rubber a hoʻemi i nā kumukūʻai, pono e hoʻohui ʻia nā mea hoʻohui like ʻole i ka ʻōpala maka.ʻO ka hui ʻana he kaʻina i hui pū ʻia ai ka ʻōpala maka masticated me ka mea hoʻohuihui, a ua hoʻopuehu ʻia ka mea hoʻohui i loko o ka ʻōpala maka ma o ka hui ʻana i ka mīkini hui.ʻO ka hui ʻana he hana koʻikoʻi i ka hana ʻana i nā huahana rubber.Inā ʻaʻole like ka hui ʻana, ʻaʻole hiki ke hoʻokō piha ʻia ka hopena o ka lāʻau a me nā mea hoʻohuihui, e pili ana i ka hana o ka huahana.Ua kapa ʻia ka ʻōpala i loaʻa ma hope o ka hui ʻana.ʻO ia kahi mea i hoʻopau ʻia no ka hana ʻana i nā ʻano mea like ʻole, i ʻike maʻamau ʻia ʻo ia ka lāʻau lapaʻau, i kūʻai pinepine ʻia ma ke ʻano he waiwai.Hiki i nā mea kūʻai ke hoʻohana i nā mea lāʻau lapaʻau no ka hoʻoponopono pololei ʻana, hoʻohua a vulcanize i loko o nā huahana lāʻau i makemake ʻia..E like me nā ʻano hoʻohālikelike like ʻole, aia nā ʻano o nā māka like ʻole a me nā ʻano like ʻole me nā waiwai like ʻole e koho ai.
5. Hoʻokumu
I ke kaʻina hana o nā huahana rubber, ʻo ke kaʻina hana o ka hana mua ʻana i nā ʻano like ʻole a me nā nui e nā calenders a i ʻole extruders i kapa ʻia he molding.
6.Vulcanization
ʻO ke kaʻina hana o ka hoʻololi ʻana i ka lāʻau palaki i ka lāʻau elastic i kapa ʻia ʻo vulcanization.ʻO ia ka hoʻohui ʻana i kahi nui o ka mea vulcanizing e like me ka sulfur, vulcanization accelerator, a me nā mea ʻē aʻe. no laila e lilo ai ka mea hoʻohui ʻia i ka vulcanizate elastic loa.
