Me pēhea te whakaoti i ngā mamae tukatuka noa ongā puranga matua tae me ngā puranga matua whakakī
Ko te tae tētahi o ngā huānga tino whakapuaki, te huānga āhua tino tairongo e taea ai e tātou te whakaharikoa i te ataahua o te ao whānui. Ko ngā tae masterbatch hei reo mō te tae, e whakamahia whānuitia ana i roto i ngā momo hua kirihou e pā tata ana ki tō tātou oranga o ia rā, e tāpiri ana i ngā tae kanapa ki tō tātou oranga. Hei tāpiri, i roto i ngā hua kirihou, he mea nui anō hoki te whakakī masterbatch ki te whakaiti i te utu o ngā hua, te whakapai ake i te pai o te whakaputa, te whakarei ake i te pakari o ngā hua me ētahi atu āhuatanga e whai wāhi nui ana.
Ngā Wāhi Mamae Tukatuka Noa oNgā puranga matua tae me ngā puranga matua whakakī:
He momo tae motuhake hou te tae matua mō ngā rauemi polymer. Kia taurite ai te horapa o te tae i roto i te tae matua, kia kore ai e pupū ake, kia pai ake ai te ātete o te tae ki te rangi, kia pai ake ai te horapa me te kaha tae o te tae, he mea tika kia tāpirihia he wai whakamarara ki roto i te tukanga.
Ko te whakakī matua he mea tito mai i te kapia kawe, te whakakī me ngā momo tāpiringa. I roto i te tukanga whakaputa o te whakakī matua, hei whakapai ake i te rere o te tukatuka o te masterbatch me te whakatairanga i te horapa ōrite o te masterbatch ki roto i te kapia matrix, ka whakamahia hoki ngā dispersants.
Heoi, i roto i te tukanga whakaputa tuturu he uaua ki te whakaoti i ngā raruraru e whai ake nei mō te maha o ngā mea whakamarara, ā, ka piki ake te utu whakaputa o ngā papa tae me ngā papa whakakī:
1. Te whakakotahitanga o te paura tae, te whakakotahitanga o te whakakī, ā, ka pā ki ngā hua kirihou whakamutunga, pērā i ngā hua o ngā atarangi rerekē o te tae, te hanganga o ngā matūriki mārō maha, ngā "kapua" rānei i runga i ngā hua;
2. Te kohikohinga o ngā rauemi i roto i te pokepokea ai e te waha nā te koretake o te marara i te wā e hangaia ana ngā puranga tae me ngā puranga whakakī;
3. Kāore i te rawaka te tae me te pumau o te tae o ngā puranga tae matua.
……
Paura Silicone S201He paura āwhina tukatuka kei roto ngā polysiloxanes taumaha-ngota tino teitei kua marara ki roto i te silica, i hangaia mō ngā masterbatches, ngā polyolefin/whakakī masterbatches me ētahi atu masterbatches, ka taea te whakapai ake i ngā āhuatanga tukatuka, ngā āhuatanga mata me te marara o ngā whakakī i roto i te pūnaha kirihou.Paura Silicone S201e whakamahia ana i roto i ngā masterbatch me ngā masterbatch whakakī me ēnei painga e whai ake nei:
(1) He pai ake mō te pāmahana tukatuka teitei ake i te ware pi PE, me ētahi atu;
(2) Whakapai ake i te taumata tae o ngā puranga tae matua;
(3) Whakaitihia te tūponotanga o te whakakotahitanga o ngā whakakī me ngā tae;
(4) Kia pai ake te horapa o te paura whakakī me te paura tae, kia ōrite ai te horapa i roto i te kapia kawe;
(5) Ngā āhuatanga rheological pai ake (te rere, te iti o te pēhanga mate me te taipana extrusion), te whakaiti i te paheke o te tīwiri me te kohikohinga mate;
(6) Whakapai ake i te whai huatanga o te whakaputa me te whakaiti i ngā utu whakaputa;
(7) He tino pai te pumau o te wera me te pumau o te tae.
Haunga ngā puranga matua me ngā puranga matua whakakī,Paura Silicone S201Ka taea hoki te whakamahi i roto i ngā hononga waea me te taura, ngā rauemi PVC, ngā kirihou hangarau me te maha atu o ngā mara. Mā te tāpiri iti ka taea te whakapai ake i te rere o te kapia, te mahi whakakī pokepokea ai, te whakahinuhinu ā-roto me te mahi tuku pokepokea ai me te kaha whakaputa, me ētahi atu. Ina tae te nui tāpiri ki te 2%-5%, ka taea te whakapai ake i te whakahinuhinu, te whakarato i te tauwehenga waku iti iho, me te ātete pai ake ki ngā karawarawa, ngā pakaru me te pakū.
