Introduction to Rubber Industry Terminology (1/2)

Hoʻokomo ʻia ka ʻoihana lāʻau lapaʻau i nā ʻano huaʻōlelo loea, ma waena o ka latex hou e pili ana i ka wai keʻokeʻo i ʻoki pololei ʻia mai nā kumulāʻau lāʻau.

Hoʻokaʻawale ʻia ka lāʻau maʻamau i 5, 10, 20, a me 50 ʻāpana ʻāpana, ma waena o ka SCR5 e loaʻa i ʻelua ʻano: emulsion rubber a me gel rubber.

Hoʻopili ʻia ka waiu maʻamau ma o ka hoʻopaʻa pono ʻana, ka granulating, a me ka hoʻomaloʻo ʻana i ka latex, ʻoiai ke hoʻonohonoho ʻana i ka mea hoʻopili maʻamau e hana ʻia ma ke kaomi ʻana, granulating, a me ka hoʻomaloʻo ʻana i ka ea maloʻo kiʻi.

Mooney viscosity he hōʻailona ia no ke ana ʻana i ka torque i koi ʻia no ka hoʻololi ʻana i ka rotor i loko o kahi lua mold rubber ma lalo o nā kūlana kikoʻī.

ʻO kapulu maloo ʻO ka ʻike e pili ana i ka grams i loaʻa ma ka hoʻomaloʻo ʻana i ka 100g o ka latex ma hope o ka paʻa ʻana o ka waikawa.

Ua maheleia ka Rubber ipulu maka avulcanized rubber, ʻo ka mua he lāʻau maka a ʻo ka hope he lāʻau crosslinked.

He mea hoohuihui he mea kemika i hoʻohui ʻia i ka ʻōpala maka e hoʻomaikaʻi i ka hana o nā huahana lāʻau.

Pāpaʻa synthetic he polimer elastic loa i hana ʻia e ka polymerizing monomers.

Lapa hana hou he mea i hana ʻia mai ka ʻōpala ʻōpala i hana ʻia a me ka ʻōpala ʻōpala vulcanized.

Nā mea hana vulcanizing hiki ke hoʻopili i ka lāʻau lapaʻau, ʻoiaie wela ana ʻo ia ke ʻano o ka vulcanization.

Nā mea hana hoʻoikaika anā mea hoʻopihapiha hoʻomaikaʻi i nā waiwai kino o ka lāʻau a hoʻemi i nā kumukūʻai.

Nā mea hoʻopalupalu or plasticizers hoʻonui i ka plasticity rubber, ʻoiaiʻelemakule lāʻau ʻo ia ke kaʻina o ka nalo mālie ʻana i nā waiwai lāʻau.

ʻO nā antioxidants hoʻopaneʻe a keʻakeʻa paha i ka ʻelemakule a ua hoʻokaʻawale ʻia i kemika a me ke kino anti-aging agents.

Hoʻopā hau asulfur spraying e nānā i ke ʻano o ka sulfur a me nā mea hoʻohui ʻē aʻe e puhi ana i waho a me ka sulfur precipitating a crystallizing, kēlā me kēia.

ʻO ka palaki ʻO ia ke kaʻina hana o ka hoʻololi ʻana i ka ʻōpala maka i mea palaki, hiki ke mālama i ka deformation ma lalo o ke kaumaha.

Huihui ʻo ia ke kaʻina hana o ka hoʻohui ʻana i kahi mea hoʻohui i ka lāʻau e hana ai i kahi hui lāʻau, ʻoiaika uhi ʻana ʻO ke kaʻina hana o ka hoʻopili ʻana i kahi slurry ma luna o ka ʻili o kahi lole.

ʻO ka ʻōwili ʻana ke kaʻina hana o ka hana ʻana i nā kiʻiʻoniʻoni semi-hoʻopau a i ʻole nā ​​lipine mai ka lāʻau kāwili. ʻO ke koʻikoʻi tensile, ke koʻikoʻi ʻoi loa, a me ka elongation i ka wā haʻihaʻi e hōʻike ana i ke kūpaʻa deformation, ke kūpaʻa ʻino, a me nā ʻano deformation o ka vulcanized rubber, kēlā me kēia.

Kaha waimaka hōʻike i ka hiki o nā mea hana ke pale aku i ka hoʻolaha ʻana o ka māwae, ʻoiaikāpalapa paakiki aʻaʻahuhoike ka hiki o ka lāʻau ke kūʻē i ka deformation a me ka ʻaʻahu o ka ʻili, kēlā me kēia.

Lapamānoanoae pili ana i ka nuipa o ka lapepa no ka huina nui.

Ka pale ʻana i ka luhi pili i ka hoʻololi ʻana a me ka hana ʻana o ka lāʻau ma lalo o nā ikaika o waho.

ʻO ka makua e pili ana i ke kaʻina hana o nā ʻōpala kaʻa kaʻa, a ʻo ka manawa o ka oʻo ʻana mai ka paʻa ʻana o ka latex a hiki i ka dehydration.

Kahakai He paʻakikī: ʻO ka paʻakikī e pili ana i ka hiki ke pale aku i ka hoʻouka kaua o waho, i hoʻohana ʻia e hōʻike i ke kiʻekiʻe o ka paʻakikī o ka lāʻau. Hoʻokaʻawale ʻia ka paʻakikī o kahakai i A (ana ʻana i ka ʻōpala palupalu), B (ana ana i ka lāʻau semi-rigid), a me C (ana ana i ka lāʻau paʻa).

Ka ikaika tensile: ʻO ka ikaika tensile, ʻike ʻia hoʻi ʻo ka ikaika tensile a i ʻole ka ikaika tensile, pili i ka ikaika o kēlā me kēia ʻāpana i hana ʻia ma luna o ka lāʻau i ka wā e huki ʻia ai, i hōʻike ʻia ma Mpa. ʻO ka ikaika tensile kahi hōʻailona koʻikoʻi no ke ana ʻana i ka ikaika mechanical o ka lāʻau, a ʻoi aku ka nui o kona waiwai, ʻoi aku ka maikaʻi o ka ikaika o ka lāʻau.

Tensile elongation ma ka haki, ʻike ʻia hoʻi ʻo elongation, pili i ka ratio o ka lōʻihi i hoʻonui ʻia e ka ʻāʻī ʻana o ka lāʻau i ka wā i huki ʻia ai i kona lōʻihi kumu, i hōʻike ʻia ma ke ʻano he pakeneka (%). He hōʻailona hana ia no ke ana ʻana i ka plasticity o ka lāʻau, a ʻo ke kiʻekiʻe elongation rate e hōʻike ana he ʻano palupalu ka ʻōpala a me ka plasticity maikaʻi. No ka hana ʻana o ka lāʻau, pono e loaʻa kahi elongation kūpono, akā ʻaʻole maikaʻi ka nui.

Laki hou hou, ʻike ʻia ʻo rebound elasticity a i ʻole elasticity hopena, he hōʻailona hana koʻikoʻi no ke ana ʻana i ka elasticity rubber. ʻO ka lakio o ke kiʻekiʻe o ka rebound i ke kiʻekiʻe kumu i ka wā e hoʻohana ai i ka pendulum e hoʻopili ai i ka lāʻau i kekahi kiʻekiʻe i kapa ʻia ʻo ka rebound rate, i hōʻike ʻia ma ke ʻano he pākēneka (%). ʻO ka nui o ka waiwai, ʻoi aku ka kiʻekiʻe o ka elasticity o ka lāʻau.

Wehe i ka deformation mau, i ʻike ʻia he deformation mau loa, he hōʻailona koʻikoʻi no ke ana ʻana i ka elasticity o ka lāʻau. ʻO ia ka lakio o ka lōʻihi i hoʻonui ʻia e ka ʻāpana deformed o ka lāʻau ma hope o ke kikoo ʻia a huki ʻia a hoʻopaʻa ʻia no kekahi manawa (maʻamau 3 mau minuke) i ka lōʻihi kumu, i hōʻike ʻia ma ke ʻano he pakeneka (%). ʻO ka liʻiliʻi o kona anawaena, ʻoi aku ka maikaʻi o ka elasticity o ka lāʻau. Eia kekahi, hiki ke ana ʻia ka elasticity o ka lāʻau e ka compressive permanent deformation.
