Me pēhea te whakaoti i ngā uauatanga tukatuka o ngā rauemi taura kore-halogen he iti te paowa?

Ko te LSZH he whakarāpopototanga mō ngā halogens kore paowa iti, kore-haumanu, he iti noa te paowa e tukuna ana e tēnei momo taura me te waea, ā, kāore e tukuna he halogens paitini ina pāngia e te wera. Heoi, hei whakatutuki i ēnei huānga matua e rua, i roto i te hanga rauemi taura kore-haumanu, he nui te utaina o ngā halogens kore-paowa iti (LSZH), e hua tika ana hoki ki ngā āhuatanga miihini me te tukatuka.

Ngā uauatanga o te tukatuka i ngā rauemi kore-halogen paowa iti:

1. He tauira noa, he nui te ihirangi o ngā matū taura polyolefin LSZH kua whakakīia ki te LLDPE/EVA/ATH, ā, kei roto i ēnei matū taura tae atu ki te 55-70% ATH/MDH. Nā te mea he iti te nekenekehanga o te pūnaha i roto i te maha o ngā konumohe hauwai, te konupora hauwai, me ētahi atu mea ārai mura, ka piki ake te pāmahana i te wā e tukatukahia ana, ka pakaru te konumohe me te konupora hauwai.

2. He iti te pai o te whakaputanga, ahakoa ka tere ake te whakaputanga, ka rite tonu te rahinga whakaputanga.

3. Kāore i te hototahi pai ngā aukati mura kore-waro me ngā whakakī ki ngā polyolefin, kāore i te marara pai i te wā tukatuka, ā, ka heke iho ngā āhuatanga hangarau.

4. He mata taratara, he kore kanapa i te wā e whakaputa ana nā te koretake o te mararatanga o ngā ārai mura kore-waro i roto i te pūnaha.

5.Nā te āhua rerekē o te hanganga o ngā ārai mura me ngā whakakī ka piri te wai rewa ki te pane o te pokepokea ai, ka whakaroa i te tukunga o te rauemi mai i te pokepokea ai, ka pupū ake rānei ngā ngota iti i roto i te hanganga, ka hua ake he puranga rauemi i te whakatuwheratanga o te pokepokea ai, ka pā ki te kounga o te taura.

I runga i ngā take o runga ake nei, kua whakawhanakehia e SILIKE he raupapa otāpiri siliconehe hua i hangaia motuhake hei whakatika i ngā uauatanga o te tukatuka me te kounga o te mata o ngā rauemi taura kore-halogen iti-paoa, ngā matū waea me ngā taura halogen iti-paoa kore, ētahi atu matū Polyolefin kī tonu i te kohuke mō ngā tono waea me te taura, e whakarato ana i te whānuitanga o ngā otinga whai hua ki ēnei wero.

Hei tauira:Pūmua Hiraka (Siloxane Masterbatch) LYSI-401He ranunga i hangaia ki te pellets me te 50% o te siloxane polymer taumaha-rahi tino teitei i whakamararatia ki roto i te polyethylene iti-kiato (LDPE). He whānuitia te whakamahinga hei tāpiri tukatuka whai hua i roto i ngā pūnaha kapia hototahi ki te PE hei whakapai ake i ngā āhuatanga tukatuka me te whakarerekē i te kounga o te mata.

Tāpirihia te 0.5-2% oSILIKE silicone masterbatch LYSI-401Mā te pūnaha whakakī ātete mura nui o ngā rauemi waea me te taura kore-halogen paowa iti, ngā rauemi taura rānei LSZH kore-halogen paowa iti (LSZH) ka taea e ngā kaihanga waea me te taura te whakanui ake i te hua, ka taea te whakapai ake i te rere o te tukatuka, te whakaiti i te taipana, te tere ake o te raina whakaputa mata me te kore he hekenga, te whakapai ake i te kounga o te mata o te waea me te taura, (He iti ake te tauwehenga o te waku, he pai ake te ātete ki te rakuraku me te kakahu, he pai ake te paheke o te mata, me te kare ā-ringa…) me te kore e utu nui mō ngā tāpiringa mahi kore e hiahiatia.

I te nuinga o te wā, mō te Noapuranga matua silicone, he kore-polar te siloxane, ā, he tino nui te rerekētanga o te nuinga o ngā tawhā wairewa o te mekameka waro, ko te tāpiri o te maha o ngā take ka arahi pea ki te tukatuka o te paheke o te tīwiri, te hinuhinu nui, te wehewehenga o te mata o te hua, ka pā ki te mata o ngā hua o ngā āhuatanga here o ngā hua i roto i te papa e marara koretake ana, me ētahi atu.

I a,Ngā tāpiri silicone taumaha-teitei rawa atu a SILIKEka whakarerekētia e ngā rōpū motuhake, ka taea te whiriwhiri me te whakataurite kia rite ki ngā hiahia rerekē o ngā tāpiringa silicone i roto i ngā papa rerekē. Ka taea e tēnei raupapa hua te mahi hei punga i roto i te papa, kia pai ake ai te hototahi ki te papa, kia māmā ake ai te horapa, kia kaha ake ai te hononga, ā, kia pai ake ai te mahi a te papa. Ina whakamahia i roto i ngā pūnaha LZSH me HFFR, ka taea te karo i te paheke o te tīwiri, ā, ka taea hoki te mahi nui ki te whakapai ake i te kohikohinga o ngā rauemi i roto i te pokepokea ai te waha.
