Rapa Styrene Teitei / HSR 60 / HSR 68 / HSR 80 / HSR 85 utu pai
He momo motuhake te rapa styrene butadiene te rapa styrene-teitei. He pūmua kore-porora i hangaia mai i te whakakotahitanga o te styrene me te butadiene latex. Hanganga matū:
—(CH2—CH=CH—CH2)m—(CHC6H5—CH2)n—
He kirikiri mā, kāore he paitini, kāore he kakara, ā, he ngāwari ki te mura. Te pāmahana whakapōturi wera: 70-90℃, he mā totoka. E whakamahia ana hei whakakī whakakaha hei whakapai ake i te pakeketanga, te ātete ki te koroheketanga, te ātete ki te kakahu, te kaha haehae me te kaha kume o ngā rapa. He tino pai te āhua o te wera me te ārai hiko.
He pai te rapa styrene teitei mō te hanga hua pakeke-nui me ngā hua iti-kiato.
1. Te hanga hū: kapu mārō, rekereke, kapu pahuka mārō, hū hiako rūpahu me ētahi atu;
2. Hei rauemi papa: tāera papa rapa; ngā hua ahumahi, pērā i te rōra rapa, te horoi, te ngongo rapa mārō me ētahi atu hua hautai;
3. Ahumahi hākinakina: pōro, reti reti;
4. Rauemi ārai hiko;
5. Tāia uhi pahikara kounga teitei; he roera pastern tānga rerekē; he rapa pereti;
6.ABS, kirihou AS;
I ngā tau tata nei, kua nui ake te aro o te hunga rapa ki te whakapakari i te rapa styrene nui, inā koa i roto i te umanga motuka, pērā i te mea e whakamahia ana i roto i ngā potae. Nō reira, he tino nui te mākete pea mō te HSR. Ka taea e tā mātou HSR te whakakapi i te NIPOL HS850, HS860&HS870, JSR0060 me te KER1904 me te HS260 o Hapani.
I roto i te putea hiato kaha-teitei kua whakakikoruatia ki te putea whatu PE/pēke pepa kraft hiato, te taumaha kupenga 20kg. Ārai i te ahi, te wai me te rā. Penapena ki te wāhi hauhautanga, hauhautanga hoki.
