Utu pai Rubber Styrene High / HSR 60 / HSR 68 / HSR 80 / HSR 85
Ko te rapa styrene teitei he momo motuhake o te rapa styrene butadiene. He waerau kore-polar i mahia mai i te whakakotahitanga tahi o te styrene me te taherapa butadiene. Hanganga matū:
—(CH2—CH=CH—CH2)m—(CHC6H5—CH2)n—
He kirikiri ma, kore-paitini, horekau me te mura. Te wera o te wera: 70-90 ℃, ma te totoka. Ka whakamahia hei whakaki i te kaihoko whakakaha ki te whakapai ake i te pakeke, te pakeke-aukati, te mau-aukati, te kaha roimata me te kaha o te rapa. He pai rawa te whakamaarama me te whakamaarama hiko
Ko te rapa styrene teitei e tika ana mo te hanga i nga hua pakeke me te iti-kiato.
1.Hoe-hanga: kapu maro, rekereke, kapu pahuka i mārō, hu hiako tauira etc.;
2.As rauemi papa: rapa papa taera; nga hua ahumahi, penei i te roera roera, te horoi, te ngongo rapa pakeke me etahi atu hua hautai;
3.Ahumahi hākinakina: pōro, rollerskate;
4.Electrical rauemi insulating;
5.High-koeke pahikara uhi potae; te maha o te roera paster; rapa papa;
6.ABS, AS kirihou;
I nga tau tata nei, kei te aro nui te mara rapa ki te whakapakari i te rapa styrene teitei, ina koa i roto i te umanga motuka, penei i te tono i roto i te tire. Ka taea e to tatou HSR te whakakapi i a Japan NIPOL HS850, HS860&HS870, JSR0060 me KER1904 me HS260 etc.
I roto i te peeke hiato kaha teitei kua whakakikoruatia ki te peeke whatu whakakikoruatia PE/peeke pepa kraft hiato, kupenga wt. 20kg. Tiaki i te ahi, te wai me te ra. Whakaorangia ki te waahi makariri me te maroke.
