He aha te Kiriata Turanga TPU?

Ko te kiriata TPU he kiriata i hangaia mai i ngā kirikiri TPU mā roto i ngā tukanga motuhake pēnei i te whakatārewatanga, te whakarewanga, te pupuhi kiriata, me te paninga. Nā te mea he āhuatanga tō te kiriata TPU ki te uruhanga makuku, te uruhanga hau, te ātete makariri, te ātete wera, te ātete kakahu, te kukū teitei, te kaha kukume teitei, me te tautoko kawenga teitei, he whānui rawa tōna whakamahinga, ā, ka kitea te kiriata TPU i ngā āhuatanga katoa o te oranga o ia rā. Hei tauira, ka whakamahia ngā kiriata TPU ki ngā rauemi tākai, ki ngā tēneti kirihou, ki ngā pūwero wai, ki ngā papanga hiato tueke, me ētahi atu. I tēnei wā, ko ngā kiriata TPU te nuinga o te wā e whakamahia ana ki ngā kiriata tiaki peita i roto i te ao motuka.

Mai i te tirohanga hanganga, ko te kiriata tiaki peita TPU te nuinga o te wā he paninga mahi, he kiriata turanga TPU me te paparanga piri. I roto i ēnei, ko te kiriata turanga TPU te wāhanga matua o te PPF, ā, he mea tino nui tōna kounga, ā, he tino teitei ngā whakaritenga mō tōna mahi.

E mōhio ana koe ki te tukanga whakaputa o TPU?

Te whakamaroke me te whakamaroke: te whakamaroke i te tātari ngota, neke atu i te 4h, te makuku <0.01%

Te pāmahana tukatuka: tirohia ngā rauemi mata i tūtohutia e ngā kaihanga, kia rite ki te pakeketanga, ngā tautuhinga MFI

Tātari: whai i te huringa whakamahinga, hei ārai i ngā ira pango o ngā mea ke

Papu rewa: te whakau i te rōrahi o te extrusion, te whakahaere porowhita kati me te extruder

Tīwiri: Kōwhiria he hanganga kutikuti iti mō te TPU.

Pane mate: hoahoahia te awa rere kia rite ki te rheology o te rauemi TPU aliphatic.

He mea nui ia taahiraa ki te hanga PPF.

E whakaahua poto ana tēnei pikitia i te tukanga katoa o te tukatuka i te polyurethane thermoplastic aliphatic mai i te puranga matua granular ki te kiriata. Kei roto ko te ranunga o te rauemi me te pūnaha whakamaroke me te whakamaroke, e whakamahana ana, e kutikuti ana, e whakakirikiri ana i ngā matūriki totoka kia rewa (rewa). I muri i te tātari me te ine, ka whakamahia te mate aunoa hei hanga, hei whakamatao, hei whakauru i te PET, me te ine i te matotoru.

Ko te tikanga, ka whakamahia te ine matotoru o te hihi-X, ā, ka whakamahia he pūnaha whakahaere huna me te urupare kino mai i te pane mate aunoa. Hei whakamutunga, ka mahia te tapahi taha. Whai muri i te tirotiro hapa, ka tirotirohia e ngā kaitirotiro kounga te kiriata mai i ngā koki rerekē kia kite ai mēnā ka tutuki ngā āhuatanga ā-tinana i ngā whakaritenga. Hei whakamutunga, ka pōkaihia ngā rōra ka tukuna ki ngā kaihoko, ā, ka whai tukanga pakari i waenganui.

Ngā pūwāhi hangarau tukatuka

TPU masterbatch: TPU masterbatch i muri i te pāmahana teitei

mīhini whakarewa;

Kiriata TPU;

Te whakapiri i te mīhini paninga: Ka whakatakotoria te TPU ki runga i te mīhini paninga whakamahana/whakatakoto-mārama, ā, ka pania ki te paparanga o te kāpia kiriaku/kāpia whakamaroke mārama;

Te Whakakikorua: Te whakakikorua i te kiriata tuku PET ki te TPU piri;

Paninga (paparanga mahi): paninga nano-waipiro i runga i te TPU i muri i te whakakikoruatanga;

Te whakamaroke: te whakamaroke i te kāpia i runga i te kiriata mā te tukanga whakamaroke e haere tahi mai ana me te mīhini paninga; ka puta he iti noa te hau para koiora i tēnei tukanga;

Te tapahi: E ai ki ngā whakaritenga o te ota, ka tapahia te kiriata whakahiato ki ngā rahi rerekē e te mīhini tapahi; mā tēnei tukanga ka puta ngā taha me ngā kokonga;

Te hurihuri: ka takaihia te kiriata huri tae i muri i te tapahi ki roto i ngā hua;

Te tākai hua kua oti: te tākai i te hua ki roto i te whare putunga.
