1. ʻAiʻoniʻoni
Ka wehewehe ʻana i nā huaʻōlelo ʻepekema a me ka ʻenehana: ʻO nā hiʻohiʻona volumetric o ka wai, pseudo-liquid a i ʻole pseudo-solid mea kūʻē i ke kahe, ʻo ia hoʻi, ka friction kūloko a i ʻole ke kū ʻana i loko o ke kahe ma waena o nā molekala i ka wā e kahe ai ma lalo o ka hana o ka ikaika o waho.Ma lalo o nā kūlana maʻamau, pili pono ka viscosity i ka paʻakikī.
2. Oolea
ʻO ka hiki i kahi mea ke kūʻē i nā mea paʻakikī i kaomi ʻia i loko o ka ʻili i kapa ʻia ʻo ka paʻakikī.He 10 a hiki i ka 80 ka paakiki o ka Silicone rubber, ka mea i haawi i na mea hana i ke kuokoa holookoa e koho i ka paakiki e pono ai e hookō pono i na hana.Hiki ke hoʻokō ʻia nā waiwai paʻakikī waena ma ka hui ʻana i nā substrate polymer, nā mea hoʻopihapiha a me nā mea hoʻohui i nā ʻano like ʻole.Pēlā nō, hiki i ka manawa a me ka mahana o ka wela a me ka ho'ōla ke hoʻololi i ka paʻakikī me ka ʻole o ka luku ʻana i nā ʻano kino ʻē aʻe.
3. Ka ikaika tensile
ʻO ka ikaika tensile e pili ana i ka ikaika i koi ʻia i kēlā me kēia ʻāpana ʻāpana e hoʻohiolo ai i kahi ʻāpana lāʻau lapaʻau.ʻO ka ikaika tensile o ka ʻili silikoni paʻa thermally vulcanized ma waena o 4.0-12.5MPa.ʻO ka ikaika tensile o ka fluorosilicone rubber ma waena o 8.7-12.1MPa.ʻO ka ikaika tensile o ka wai silicone rubber ma ka laulā o 3.6-11.0MPa.
ʻEhā, ikaika waimaka
ʻO ke kū'ē e keʻakeʻa ana i ka hoʻonui ʻia ʻana o ka ʻoki a i ʻole ka helu ʻana ke hoʻohana ʻia ka ikaika i ka hāpana ʻoki.ʻOiai inā e kau ʻia ma lalo o ke koʻikoʻi torsional kiʻekiʻe loa ma hope o ka ʻoki ʻana, ʻaʻole hiki ke haehae ʻia ka pahu silika paʻa thermally vulcanized.Aia ma waena o 9-55 kN/m ka nui o ka ikaika o ka waimaka.Aia ma waena o 17.5-46.4 kN/m ka ikaika o ka waimaka o ka fluorosilicone rubber.ʻO ka ikaika o ka waimaka o ka ʻili silicone wai mai 11.5-52 kN/m.
5. Elongation
E pili ana i ka "Ultimate Break Elongation" a i ʻole ka hoʻonui pākēneka e pili ana i ka lōʻihi kumu i ka wā e haki ai ka hāpana.He elongation ka lōʻihi ma waena o 90 a 1120%.ʻO ka lōʻihi o ka fluorosilicone rubber ma waena o 159 a 699%.ʻO ka elongation maʻamau o ka wai silicone rubber ma waena o 220 a 900%.Hiki i nā ʻano hana like ʻole a me ke koho ʻana o ka hardener ke hoʻololi nui i kona elongation.ʻO ka elongation o ka silicone rubber ka mea nui e pili ana i ka mahana.
6, manawa hana
Hoʻopili ʻia ka manawa hana mai ka manawa i hoʻohui ʻia ai ka colloid i ka mea vulcanizing agent.ʻAʻohe palena piha ma waena o kēia manawa hana a me ka manawa vulcanization ma hope.Ua loaʻa i ka colloid ka hopena vulcanization mai ka manawa i hoʻohui ʻia ai ka mea vulcanizing.ʻO kēia manawa hana ʻo ia ka 30-minute vulcanization reaction o ka huahana ʻaʻole pili i ka maikaʻi o ka huahana i hoʻopau ʻia.No laila, ʻoi aku ka nui o ka manawa i mālama ʻia i ke kaʻina hana huahana, ʻoi aku ka maikaʻi o ka huahana i hoʻopau ʻia.
7, manawa ho'ōla
E ʻōlelo kekahi mau wahi he manawa hoʻōla.I nā huaʻōlelo ʻē aʻe, ua pau ka hopena vulcanization o ka silica gel ma hope o ka manawa lōʻihi.Hoʻopau maoli kēia, ʻo ia hoʻi ua loaʻa ka huahana, akā ʻoiaʻiʻo aia nō kahi ʻāpana liʻiliʻi o ka hopena curing ʻaʻole i pau.No laila, ʻo nā huahana i hana ʻia me ka silicone rubber, e like me ka silicone molds, e lawe mau i kahi manawa ma mua o ka hoʻohana ʻana.
ʻO Silica gel (Silica gel; Silica) alias: ʻO ka silica gel kahi mea hoʻoheheʻe ikaika loa, ʻo ia ka mea amorphous.ʻO kona ʻano kemika he mSiO2·nH2O;ʻAʻole ia e hana me kekahi mea koe wale nō ka alkali ikaika a me ka waika hydrofluoric.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe, ʻaʻohe mea ʻawaʻawa, ʻono ʻole, a paʻa kemika.Hoʻokumu ʻia nā ʻano like ʻole o ka silica gel i nā ʻano microporous like ʻole ma muli o kā lākou ʻano hana hana like ʻole.ʻO ka hoʻohui kemika a me ke ʻano kino o ka silica gel e hoʻoholo ai he nui nā mea like ʻē aʻe i paʻakikī ke hoʻololi: ka hana adsorption kiʻekiʻe, ke kūpaʻa wela maikaʻi, nā waiwai kemika paʻa, a me ka ikaika mechanical kiʻekiʻe.E like me ka nui o kona nui pore, ua māhele ʻia ka silica gel i: macroporous silica gel, coarse pore silica gel, B-type silica gel, fine pore silica gel, etc.
ʻO ke kumu kūʻai o nā mea silicone i kēia manawa he paʻa loa, piʻi i kēlā me kēia lā, paʻakikī iā mākou ke hoʻoholo i ke kumukūʻai.Hiki iā mākou ke hana walenā mea hoʻoheheʻe siliconei kēia manawa.
