ʻO SC 920 ka mea kōkua kaʻina hana silikoni kūikawā no ka LSZH a me ka HFFR mau mea kelepona kahi huahana i haku ʻia i nā hui hana kūikawā o polyolefins a me co-polysiloxane. Hiki i ka polysiloxane i loko o kēia huahana ke hoʻokani i kahi hana kuʻuna i ka substrate ma hope o ka hoʻololi ʻana i ka copolymerization, i ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana me ka substrate, a ʻoi aku ka maʻalahi o ka hoʻopuehu ʻana, a ʻoi aku ka ikaika o ka paʻa, a laila hāʻawi i ka substrate i ka hana maikaʻi loa. Hoʻohana ʻia ia e hoʻomaikaʻi i ka hana ʻana o nā mea i loko o ka ʻōnaehana LSZH a me HFFR, a kūpono ia no nā kaula extruded kiʻekiʻe, hoʻomaikaʻi i ka hoʻopuka, a pale i ka hanana extrusion e like me ke anawaena uea paʻa ʻole a me ka slip slip.
Papa | SC920 |
Ka nana aku | pellet keʻokeʻo |
Ka helu helu hehee (℃) (190℃,2.16kg)(g/10min) | 30~60(waiwai maʻamau) |

1, Ke hoʻohana ʻia i ka ʻōnaehana LSZH a me HFFR, hiki ke hoʻomaikaʻi i ke kaʻina hana extrusion o ka waha make accumulation, kūpono no ka extrusion kiʻekiʻe o ke kaula, hoʻomaikaʻi i ka hana, pale i ke anawaena o ka laina instability, screw slip a me nā mea extrusion ʻē aʻe.
2, Hoʻomaikaʻi nui i ka flowability kaʻina hana, hoʻemi i ka viscosity heheʻe i ke kaʻina hana o nā mea halogen-free flame-retardant kiʻekiʻe, hoʻemi i ka torque a me ka hoʻoili ʻana i kēia manawa, hoʻemi i ka ʻaʻahu o nā mea hana, hoʻemi i ka helu hemahema o ka huahana.
3, E ho'ēmi i ka hōʻiliʻili ʻana o ke poʻo make, e hoʻemi i ka mahana hana, e hoʻopau i ka hehee ʻana a me ka decomposition o nā mea maka i hoʻokumu ʻia e ke kiʻekiʻe o ka hana wela, e hana i ka ʻili o ka uea extruded a me ke kaula i ʻoi aku ka māmā a me ka mālamalama, e hoʻemi i ka koena friction o ka ʻili. ka huahana, hoʻomaikaʻi i ka hana maʻemaʻe, hoʻomaikaʻi i ka luster o ka ʻili, hāʻawi i ka manaʻo maʻalahi, hoʻomaikaʻi i ka pale ʻana.
4, Me ka silicone polymer kūikawā i hoʻololi ʻia e like me ka mea hoʻoikaika, hoʻomaikaʻi i ka hoʻopuehu ʻana o nā mea pale ahi i loko o ka ʻōnaehana, hāʻawi me ka paʻa maikaʻi a me ka neʻe ʻole.
Ma hope o ka hui ʻana o SC 920 me ka resin i ka like, hiki ke hana pololei a hoʻohana ʻia paha ma hope o ka granulation. ʻO ka nui o ka hoʻohui i manaʻo ʻia: Ke 0.5% -2.0% ka nui o ka hoʻohui, hiki iā ia ke hoʻomaikaʻi i ka processability, fluidity a me ka hoʻokuʻu ʻana o ka huahana; Ke hoʻonui ʻia ka nui o ka 1.0% -5.0%, hiki ke hoʻomaikaʻi ʻia nā waiwai o ka ʻili o ka huahana (smoothness, hoʻopau, scratch resistance, wear resistance, etc.)
25Kg / ʻeke, ʻeke pepa hana
Ka lawe ʻana ma ke ʻano kemika ʻaʻole pilikia. E mālama i loko o kahi anuanu a maikaʻi.
Hoʻomau mau ʻia nā hiʻohiʻona kumu no 24 mau mahina mai ka lā hana, inā mālama ʻia i loko o kahi waiho ʻōlelo.
