Ni ubuhe buryo bwo gushonga bwa plastiki?

Plastike y'ibikoresho bitandukanye ifite ingingo zitandukanye zo gushonga:
Polypropilene: Ubushyuhe bwo gushonga ni 165 ° C - 170 ° C, ituze ryumuriro ni ryiza, ubushyuhe bwangirika bushobora kugera hejuru ya 300 ° C, kandi bugatangira guhinduka umuhondo no kwangirika kuri 260 ° C mugihe uhuye na ogisijeni. , kandi ifite anisotropy mugihe cy'ubushyuhe buke.Nibyoroshye guhindagurika cyangwa kugoreka kubera icyerekezo cya molekile, kandi gifite imikorere myiza.Ibice bya resin bifite ibishashara.Ikigereranyo cyo kwinjiza amazi kiri munsi ya 0,02%.Ibicuruzwa byemewe byemewe kubumba ni 0,05%.Kubwibyo, gukama ntibisanzwe bikorwa mugihe cyo kubumba.Irashobora gukama nka 80 ° C mumasaha 1-2, kandi imigezi yacyo itumva ubushyuhe nigipimo cyogosha mugihe cyo kubumba.

Polyoxymethylene: Ni plastiki itumva ubushyuhe ifite ubushyuhe bwa 165 ° C, izabora cyane kandi ihinduke umuhondo ku bushyuhe bwa 240 ° C.Igihe cyo gutura ku bushyuhe bwa 210 ° C ntigomba kurenza iminota 20.Muburyo busanzwe bwo gushyushya, bizabora niba bishyushye igihe kirekire., Nyuma yo kubora, hazabaho impumuro mbi no kurira.Ibicuruzwa biherekejwe numurongo wumuhondo-umukara.Ubucucike bwa POM ni 1.41—1.425.Amasaha 5.
Polyakarubone: itangira koroshya kuri 215 ° C, itangira gutemba hejuru ya 225 ° C, gushonga kwijimye munsi ya 260 ° C ni hejuru cyane, kandi ibicuruzwa bikunda kubura.Ubushyuhe bwo kubumba buri hagati ya 270 ° C na 320 ° C.Niba ubushyuhe burenze 340 ° C, kubora bizabaho, nubushyuhe bwumye Ubushyuhe buri hagati ya 120 ℃ —130 and, kandi igihe cyo kumisha kirenze amasaha 4.Ibisigarira bya polikarubone muri rusange ni ibara ridafite ibara.
