Hītori oNgā tāpiringa silicone / Silicone masterbatch / Siloxane masterbatchme pēhea te mahi i roto ingā matū waea me te taurate ahumahi?
Ngā tāpiringa silicone me50% te pūmua silicone mahika marara i roto i te kaikawe pēnei i te polyolefin, i te kohuke rānei, me te ahua o te kirikiri, te paura rānei, e whakamahia whānuitia ana hei āwhina tukatuka i roto i te umanga waea me te taura. Ngā hua rongonui pēnei iSILOXANE MB50mahi raupapa hei hinu whakahinuhinu, hei whakarerekētanga rheological rānei i roto i te umanga waea me te taura, ā, i whakaurua tuatahitia mai i Dow Corning i te United States i ngā tau e rua tekau ki muri, kātahi karerekē te SILIKONE MASTERBATCH MB50i puta mai i te mākete me70% te pūmua silicone mahii marara i roto i te kawe pērā i te silica, me te āhua o te kirikiri, kātahi ka puta mai ngā hua mai i Chengdu Silike i te mākete mai i te tau 2004, me te ihirangi silicone mai i te 30-70% me te āhua kirikiri, paura rānei.
Me whakauru ngā tawhā hangarau o te masterbatch silicone arumoni i ngā ihirangi e whai ake nei:
(1) Ina mahi hei hinu whakahinuhinu, hei whakarerekētanga rheological rānei, kei waenga i te 5 ki te 50% te ihirangi
(2) Me hototahi te kaikawe ki te silicone, ā, me whai whakaaro ki te papa matua o te tātai a te kaiwhakamahi, me te tohu ingoa polymer me te taupū rewa o te kaikawe, kia taea ai e ngā kaiwhakamahi te tirotiro i te wā e hoahoa ana i te tātai. Mena ka whakamahia te paura kohuke kore-waro hei kaikawe, me tohu te ingoa o te paura. He mea nui te mā me te pai o ngā paura kore-waro mō ngā kaihoko, ā, me whiriwhiri i ngā paura mā me te rahi maikorona kia rite ki te taea mō te hanga.
Ina mahi hei hinu whakahinuhinu, hei whakarerekētanga rheological rānei
Mō ngā rauemi Polyethylene
E mōhiotia whānuitia ana, ko te āhuatanga o te "kiri mangō" ka puta pinepine i te wā e whakaputa ana i ngā waea me ngā taura polyethylene kua whakamahanatia, kua hipokina rānei, inā koa i te wā e whakaputa ana i te polyethylene iti-kiato raina (LLDPE) te polyethylene tino-iti rānei (ULDPE, POE rānei). Ko ngā rauemi polyethylene kua whakawhiti-hononga (ahakoa he hononga-peroxide, he hononga-silane rānei) ka pāngia e te āhuatanga "kiri mangō", nā te kore whakaaro nui ki te pūnaha whakahinuhinu i roto i te tauira rauemi. Ko te mahi o nāianei o te ao ko te tāpiri i ngā rahinga iti o ngā fluoropolymers ki te tauira, engari he nui te utu, ā, he iti te whakamahinga.
Me te iti o tesilicon taumaha ngota tino teitei(0.1-0.2%) ki te polyethylene, ki te polyethylene honohono-whiti rānei, ka taea te ārai i te whakaputanga o te "kiri mangō". I taua wā anō, me tōna pānga whakahinuhinu, ka taea te whakaiti i te taipana whakaputa kia kore ai e mutu te motuka tōia nā te taumaha rawa.
Nā te iti o te tāpiritanga o te silicone hei hinu whakahinuhinu, me taurite te horapa o te silicone ki roto i te rauemi kia pai ai te mahi i te wā e tukatukahia ana. Nā te koretake o te silicone, e kore e tauhohe matū ki ngā wāhanga o te tauira. E taunakihia ana kia whakaranua te silicone e te wheketere rauemi taura ki roto i te tukanga whakapūkara kirihou hei whakahaere i te whakamahinga o te wheketere taura.
MōNgā matū taura ārai mura kore-halogen (HFFR)
Nā te nui o ngā mea ārai mura (paura kohuke) i roto i ngā taura HFFR, ka hua ake he matotoru teitei, ā, he ngoikore te rere i te wā e tukatukahia ana; Nā te matotoru teitei ka uaua te tōia o te motuka i te wā e whakaputa ana, ā, nā te ngoikore o te rere ka hua ake he iti noa te kāpia e puta ana i te wā e whakaputa ana. Nō reira, ina whakaputa te wheketere taura i ngā taura kore-halogen, ko te whai huatanga he 1/2-1/3 noa iho o te taura polyvinyl chloride.
Mā te whakamahi i tētahi nui o te silicone i roto i te tauira, ehara i te mea i pai ake te rere o te rauemi i roto i ngā tukanga me ngā tukanga, engari i pai ake hoki te ātete ahi.
