Ni gute wamenya neza kandi ugahitamo hagati ya PA6 yahinduwe na PA66 (Igice cya 1)?

Ni gute wamenya neza kandi ugahitamo hagati ya PA6 yahinduwe na PA66 (Igice cya 1)?

Kubera ko ikoranabuhanga rya nylon ryahinduwe rigenda rikura, uburyo PA6 na PA66 zikoreshwa bwagiye burushaho kwiyongera. Abakora ibikoresho bya pulasitiki benshi cyangwa abakoresha ibikoresho bya nylon ntibasobanukiwe neza itandukaniro riri hagati ya PA6 na PA66. Byongeye kandi, kubera ko nta tandukaniro rigaragara hagati ya PA6 na PA66, ibi byateje urujijo rwinshi. Ni gute PA6 na PA66 zishobora gutandukanywa, kandi zigomba gutoranywa gute?

Ubwa mbere, Inama zo kumenya PA6 na PA66:
Iyo bitwitswe, PA6 na PA66 byombi bitanga impumuro nk'iy'ubwoya cyangwa inzara byahiye. PA6 itanga urumuri rw'umuhondo, mu gihe PA66 ihiye n'urumuri rw'ubururu. PA6 ifite ubukana bwiza, ihendutse kurusha PA66, kandi ifite urugero rwo gushonga rwo hasi (225°C). PA66 itanga imbaraga nyinshi, idashobora kwangirika neza, kandi ikagira urugero rwo gushonga rwo hejuru (255°C).

Icya kabiri, Itandukaniro mu Miterere Ifatika:

• PA66:Aho gushonga: 260–265°C; ubushyuhe bw'ikirahure (imiterere y'umukungugu): 50°C; ubucucike: 1.13–1.16 g/cm³.
• PA6:Uduce duto twa polymeri tw’umweru dusa n’amata duto cyane; aho gushonga: 220°C; ubushyuhe bwo kubora: hejuru ya 310°C; ubucucike: 1.14; amazi anyurwa (amasaha 24 mu mazi kuri 23°C): 1.8%. Ifite ubushobozi bwo kudashira no kwisiga, imbaraga nyinshi za mashini, ubushobozi bwo kudashyuha no gukingira amashanyarazi, ubushobozi bwo kudashyuha cyane, ubushobozi bwo kuzimya, no kudakoresha imiti—cyane cyane ubushobozi bwo kudakoresha amavuta.

Ugereranyije na PA66, PA6 yoroshye kuyitunganya no kuyibumba, itanga ubushyuhe bwiza ku bicuruzwa byarangiye, kandi ifite ubushyuhe bwinshi bushobora gukoreshwa. Ariko, ifite ubushobozi bwo kwinjiza amazi menshi kandi ntigira ingaruka mbi ku ngano. Ntikomera cyane, ifite aho ishongesha hato, kandi ishobora gukoreshwa igihe kirekire mu bidukikije bikomeye. Igumana ubushobozi bwo guhangana n'imihangayiko mu bushyuhe bwinshi, hamwe n'ubushyuhe buhoraho bwa 105°C.

Icya gatatu, ni gute wahitamo niba ukwiye gukoresha PA66 cyangwa PA6?
Igereranya ry'imikorere hagati ya PA6 na PA66:

• Imiterere ya mekanike: PA66 > PA6
• Imikorere y'ubushyuhe: PA66 > PA6
• Igiciro: PA66 > PA6
• Aho gushonga: PA66 > PA6
• Gufata amazi: PA6 > PA66

Icya kane, Itandukaniro mu mikorere:

• Plastike z'ubuhanga za PA6Ifite imbaraga nyinshi zo gukurura, irwanya ingaruka nziza, irwanya kwangirika neza, irwanya imiti, kandi ifite ubushobozi buke bwo gukururana. Binyuze mu mpinduka nko kongera imbaraga mu birahure, kuzuza amabuye y'agaciro, cyangwa inyongeramusaruro zigabanya umuriro, imikorere yazo muri rusange ishobora kongerwa. Ikoreshwa cyane cyane mu nganda z'imodoka no mu bijyanye n'ikoranabuhanga/amashanyarazi.
• PA66Ifite imikorere myiza muri rusange, harimo gukomera cyane, gukomera, kudakora neza, kudakora neza amavuta n'imiti, kudasaza neza, no kwisiga amavuta. Irakomeye cyane mu gukomera, kudakora neza, kudakora neza, kudakora neza, no kudakora neza. Bitewe n'imbaraga zayo nyinshi ugereranyije na PA6, PA66 ikoreshwa cyane mu nganda nko gukora insinga z'amapine.
