Nigute ushobora kumenya neza no guhitamo hagati ya PA6 yahinduwe na PA66 (Igice cya 1)?

Nigute ushobora kumenya neza no guhitamo hagati ya PA6 yahinduwe na PA66 (Igice cya 1)?

Hamwe no gukura gukura kwa tekinoroji ya nylon R&D, ikoreshwa rya PA6 na PA66 ryagutse buhoro buhoro. Abakora ibicuruzwa byinshi bya plastiki cyangwa abakoresha ibicuruzwa bya nylon ntibisobanutse kubyerekeye itandukaniro riri hagati ya PA6 na PA66. Byongeye kandi, kubera ko nta tandukaniro rigaragara rigaragara hagati ya PA6 na PA66, ibi byateje urujijo rwinshi. Nigute PA6 na PA66 bashobora gutandukanywa, kandi ni gute bagomba gutoranywa?

Icyambere, Inama zo Kumenya PA6 na PA66:
Iyo yatwitse, PA6 na PA66 byombi bisohora impumuro isa nubwoya bwatwitswe cyangwa imisumari. PA6 itanga urumuri rwumuhondo, mugihe PA66 yaka numuriro wubururu. PA6 ifite ubukana bwiza, ihendutse kuruta PA66, kandi ifite aho ishonga (225 ° C). PA66 itanga imbaraga zisumba izindi, kwihanganira kwambara neza, hamwe no gushonga hejuru (255 ° C).

Icya kabiri, Itandukaniro mubintu bifatika:

• PA66:Ingingo yo gushonga: 260-265 ° C; ubushyuhe bwikirahure (leta yumye): 50 ° C; ubucucike: 1.13–1.16 g / cm³.
• PA6:Semi-mucyo cyangwa idasobanutse amata-yera ya kristaline polymer pellets; aho gushonga: 220 ° C; ubushyuhe bwangirika: hejuru ya 310 ° C; ubucucike ugereranije: 1.14; kwinjiza amazi (amasaha 24 mumazi kuri 23 ° C): 1.8%. Ifite imyambarire myiza yo kwambara no kwisiga, imbaraga za mashini nyinshi, kurwanya ubushyuhe bwiza hamwe nubushakashatsi bwamashanyarazi, imikorere myiza yubushyuhe buke, ibintu bizimya, hamwe no kurwanya imiti - cyane cyane kurwanya amavuta.

Ugereranije na PA66, PA6 biroroshye gutunganya no kubumba, bitanga urumuri rwiza rwo hejuru mubicuruzwa byarangiye, kandi bifite ubushyuhe bwagutse bwakoreshwa. Nyamara, ifite amazi menshi yo kwinjirira hamwe nuburinganire buke. Ntibikomeye, bifite aho bishonga, kandi birashobora gukoreshwa igihe kirekire mubidukikije bikaze. Ikomeza guhangana neza nubushyuhe bugari, hamwe nubushyuhe bwa serivisi bukomeza bwa 105 ° C.

Icya gatatu, Nigute twahitamo gukoresha PA66 cyangwa PA6?
Kugereranya imikorere hagati ya PA6 na PA66:

• Ibikoresho bya mashini: PA66> PA6
• Imikorere yubushyuhe: PA66> PA6
• Igiciro: PA66> PA6
• Ingingo yo gushonga: PA66> PA6
• Kwinjiza amazi: PA6> PA66

Icya kane, Itandukaniro muburyo bwo gusaba:

• PA6 yububikozifite imbaraga zingana cyane, kurwanya ingaruka nziza, kurwanya kwambara neza, kurwanya imiti, hamwe na coefficient de fraisse ugereranije. Binyuze mubihinduka nko gushimangira fibre fibre, kuzuza amabuye y'agaciro, cyangwa inyongeramusaruro ya flame retardant, imikorere yabo irashobora kurushaho kunozwa. Zikoreshwa cyane cyane munganda zitwara ibinyabiziga na electronics / amashanyarazi.
• PA66ifite ibikorwa byiza muri rusange, harimo imbaraga nyinshi, gukomera, kurwanya ingaruka, amavuta na chimique, kurwanya kwambara, no kwisiga. Irusha cyane cyane gukomera, gukomera, kurwanya ubushyuhe, no guhangana n’ibikurura. Bitewe n'imbaraga zayo nyinshi ugereranije na PA6, PA66 ikoreshwa cyane mubikorwa byinganda nko gukora amapine.
