Polyamide

Tsanangudzo Pfupi

Iko kusanganiswa kweakanaka UV kuramba, yakakwira mechini simba, kujeka kusingaperi, kutapurirana kwepamusoro uye kukwirira kwemakemikari kuramba kunovhura huwandu hwakasiyana hwekushandisa kwayo. Nzvimbo dzakajairwa dzekushandisa dziri muindasitiri yemotokari, muchina uye mainjiniya, tekinoroji yekurapa, indasitiri yemitambo nekutandara, kugadzirwa kwemagirazi, indasitiri yezvizoro uye mukurapwa kwemvura uye kusefa tekinoroji.

Product Description

Nekusarudza chaiwo monomers, munhu anogona kuwana crystallizable uye nekusingaperi pachena polyamide. Makristasi acho maduku zvokuti haaparadzi chiedza chinooneka, uye zvinhu zvacho zvinoita sepachena mumaziso emunhu—chinhu chinonzi microcry stallinity. Nekuda kwekristallinity yayo, iyo microcrystalline chimiro chinochengeta zvakakosha zvimiro senge kusagadzikana kupaza kuramba - pasina makore. Dhigirii rekristallinity harina basa, zvisinei, zvekuti harina mhedzisiro yakaipa pamaitiro ekuderera kwezvikamu zvakaumbwa. Iyo inopinda yakafanana isotropic shrinkage senge amorphous zvinhu.

Iyo yakaderera-viscous, inogara yakajeka polyamide yekuumba jekiseni.
