He whānui te rerekētanga i waenga i te rapa tpr me te rapa BR i roto i te umanga whakarewa, he tino uaua ki te wehewehe i te hunga kāore anō kia whakapā atu ki te whatunga, i tēnei rā, mai i te ariā me te take, kia taea ai e ngā hoa te wetewete hohonu i te rerekētanga i waenga i te rapa tpr me te rapa BR.
Ko te tpr te whakarāpopototanga o te Thermo-Plastic-Rubber material, ka taea te kī ko te thermo-Plastic-Rubber material. He thermo-plastic ngāwari rapa, he ngāwari, kāore he whakamomona, ā, ka taea te tukatuka tika me te whakapoapoa (pēnei i te werohanga, te extrusion, te pupuhi, me ētahi atu).
1, ko te awhe pāmahana e whakamahia ana ko -45-90 ℃, ko te tikanga he mea hanga te rauemi tpr i runga i te papa SBS, ko ōna āhuatanga matū e whai ake nei: te ātete māpere, te ātete koroheketanga whānui, te ātete pāmahana 70-75 ℃. Mena kei te hiahia koe ki ngā rauemi ātete koroheketanga pai, te ātete pāmahana, ka taea e koe te whiriwhiri i te rauemi turanga SEBS kua whakarerekētia.
2, he pai te ātete o te rapa BR ki te pakū, he pai te mahi ātete-paheke me te mimiti ru, he ngawari, he whakamarie hoki te rauemi TPR, he pai ake i te rapa, engari ko te kaha kume o te rauemi, te ātete ki te ngenge me ngā āhuatanga miihini kāore i te rite te pai ki te rapa whakamomona.
3, ngā āhuatanga taiao, he rapa ngohengohe hoa taiao te rauemi tpr, ko ngā matū kino matua pērā i te plasticizers phthalates Phthalate, nonylphenol NP, PAHs PAHs kitea, kia rite ki ngā paerewa whakamātautau tiaki taiao ROHS, REACH, EN71-3, ASTMF963.
4, ngā āhuatanga pakeke, ka taea te whakarite i te pakeke o te rauemi tpr i roto i te takutai moana 5-100 nekehanga o tōna pakeke, ka taea te whakarite i ngā rauemi whakarerekētia e hangai ana ki te SEBS ki te pakeke iti iho.
He rauemi pūmua tino ngāwari te rapa BR, he rerekētanga whakahurihuri, he ngāwari i te pāmahana rūma, ā, ka taea te whakaputa i te rerekētanga nui i raro i te mahi a te kaha iti o waho, ā, ka taea te whakahoki i te āhua taketake i muri i te tango i te kaha o waho. Nō te pūmua kore-āhua te rapa, he iti te pāmahana whakawhiti karāhe (T g), he nui rawa te taumaha ngota, neke atu i te rau mano.
Tirohia te rerekētanga i waenga i ngā wira TPR me ngā wira rapa:
He maha ngā rauemi mō te mata o ngā wira o ngā wira hurihuri, pērā i ngā wira TPU, ngā wira PP, ngā wira TPR, ngā wira PU, ngā wira TPE, ngā wira nairona, ngā wira rapa me ētahi atu.
1, He ngawari ake, he marino ake hoki ngā wira rapa BR i ngā wira TPR.
2, ki te whakaritea ki te utu, kāore e taea te hangarua i te rapa, ka taea te hangarua i te TPR, he iti ake te utu o ngā wira TPR i ngā wira rapa BR.
4, mai i te tirohanga tiaki taiao, he rauemi hou e pai ana ki te taiao te TPR, engari kāore te rapa BR e pai ana ki te taiao.
