Pūmotu matua siliconeHe momo tāpiritanga tēnei i roto i te umanga rapa me te kirihou. Ko te hangarau matatau i roto i te mara o ngā tāpiritanga silicone ko te whakamahinga o te polymer silicone taumaha-teitei (UHMW) (PDMS) i roto i ngā momo kapia thermoplastic, pērā i te LDPE, EVA, TPEE, HDPE, ABS, PP, PA6, PET, TPU, HIPS, POM, LLDPE, PC, SAN, me ētahi atu. Ā, hei pirepire kia ngāwari ai te tāpiri tika o te tāpiritanga ki te thermoplastic i te wā e tukatuka ana. Ka whakakotahi i te tukatuka pai me te utu whaitake. He ngāwari te whāngai, te whakaranu rānei i te silicone masterbatch ki roto i ngā kirihou i te wā e whakaranua ana, e whakaputa ana, e werohanga ana rānei. He pai ake i te hinu ware pi tuku iho me ētahi atu tāpiritanga hei whakapai ake i te paheke i te wā e whakaputa ana. Nō reira, he pai ake ki ngā tukatuka kirihou te whakamahi i a rātou i roto i te putanga.
Ngā Tūranga oTāpiringa Masterbatch Siliconei roto i te Whakapai ake i te Tukatuka Kirihou
Ko te silicone masterbatch tētahi o ngā whiringa rongonui mō ngā tukatuka i roto i te tukatuka kirihou me te whakapai ake i te kounga o te mata. Hei momo hinu whakahinuhinu. Ko ēnei āna mahi matua ina whakamahia ana i roto i te kapia thermoplastic:
A. Whakapai ake i te rere o te kapia me te tukatuka;
He pai ake te whakakī pokepokea ai me ngā āhuatanga tuku pokepokea ai
Whakaitihia te taipana extrude me te whakapai ake i te tere extrusion;
B. Whakapai ake i ngā āhuatanga o te mata o te kapia
Whakapai ake i te mutunga o te mata kirihou, te nekehanga maeneene, me te whakaiti i te tauwehenga waku kiri, Whakapai ake i te ātete kakahu me te ātete rakuraku;
Ā, he pai te pumau o te wera o te silicone masterbatch (ko te pāmahana pirau wera kei te 430 ℃ i roto i te hauota) ā, kāore e heke;
Te tiaki taiao;
Te pā haumaru ki te kai.
Me tohu tātou ko ngā mahi katoa o ngā silicone masterbatches kei a A rāua ko B (ngā tohu e rua i runga ake nei i whakarārangihia e mātou) engari ehara i te mea he tohu motuhake rāua engari
e tautoko ana tetahi i tetahi, ā, e tata ana te whanaungatanga.
Ngā pānga ki ngā hua whakamutunga
Nā ngā āhuatanga o te hanganga ngota o te siloxane, he iti rawa te horopeta, nō reira kāore he pānga ki te āhuatanga ā-pūkaha o ngā hua whakamutunga. I te nuinga o te wā, engari ko te roa me te kaha o te pānga ka paku piki ake, kāore he pānga ki ētahi atu āhuatanga ā-pūkaha. I te nui o te horopeta, he pānga tahi tōna me ngā kaihoko ārai mura.
Nā tōna mahi tino pai ki te ātete ki te pāmahana teitei me te pāmahana iti, kāore he pānga taha ki te ātete pāmahana teitei me te pāmahana iti o ngā hua whakamutunga. Ā, ka tino pai ake te rere o te kapia, te tukatuka, me ngā āhuatanga o te mata, ā, ka whakaitihia te COF.
Tikanga mahi
Ngā puranga matua siliconehe polysiloxane taumaha ngota tino teitei kua marara i roto i ngā kapia kawe rerekē, he momo mahi masterbatch. Ina taumaha ngota tino teiteingā puranga matua siliconeka tāpirihia ki roto i ngā kirihou nā te mea he kore-polar, ā, he iti te kaha o te mata, he auau tōna ki te heke ki te mata kirihou i te wā e rewa ana; engari, nā te mea he nui te taumaha ngota, kāore e taea te neke katoa atu. Nō reira ka kiia e mātou he ōritetanga me te kotahitanga i waenga i te hekenga me te kore-hekenga. nā tēnei āhuatanga, ka hangaia he paparanga hinu whakahinuhinu hihiri i waenga i te mata kirihou me te tīwiri.
I te haere tonu o te tukatuka, ka tangohia tonutia, ka hangaia hoki tēnei paparanga whakahinuhinu. Nō reira, ka whakapai ake tonutia te rere o te kapia me te tukatuka, ka whakaitihia te iahiko hiko, te taipana taputapu, me te whakapai ake i te putanga. I muri i te tukatuka o ngā tīwiri takirua, ka tohatohahia ngā puranga matua silicone ki roto i ngā kirihou, ka hanga he matūriki hinu 1 ki te 2-micron i raro i te karu tirotiro, ka pai ake te āhua o aua matūriki hinu, ka pai ake te ahua o te ringa, ka iti ake te COF, ā, ka nui ake te ātete ki te pakū me te rakuraku.
Mai i te pikitia ka kite tātou ka huri te silicone hei matūriki ririki i muri i te marara ki roto i ngā kirihou, ko tētahi mea me tohu e tātou ko te mararatanga te tohu matua mō ngā masterbatch silicone, ko te iti o ngā matūriki, ko te tohatoha ōrite, ko te pai ake o te hua ka puta.
