Ungahlonza kanjani kahle futhi ukhethe phakathi kwe-PA6 eguquliwe kanye ne-PA66 (Ingxenye 1)?

Ungahlonza kanjani kahle futhi ukhethe phakathi kwe-PA6 eguquliwe kanye ne-PA66 (Ingxenye 1)?

Ngokukhula okwandayo kobuchwepheshe be-R&D enayiloni elungisiwe, ububanzi bokufaka isicelo be-PA6 ne-PA66 bukhule kancane kancane. Abakhiqizi abaningi bemikhiqizo yepulasitiki noma abasebenzisi bemikhiqizo yepulasitiki enayiloni abakacaci ngomehluko phakathi kwe-PA6 ne-PA66. Ukwengeza, njengoba kungekho mehluko obonakalayo osobala phakathi kwe-PA6 ne-PA66, lokhu kubangele ukudideka okukhulu. Ingahlukaniswa kanjani i-PA6 ne-PA66, futhi kufanele zikhethwe kanjani?

Okokuqala, Amathiphu Wokuhlonza i-PA6 ne-PA66:
Uma kushisiwe, kokubili i-PA6 ne-PA66 zikhipha iphunga elifana noboya obushile noma izinzipho. I-PA6 ikhiqiza ilangabi eliphuzi, kuyilapho i-PA66 ivutha ilangabi eliluhlaza okwesibhakabhaka. I-PA6 inokuqina okungcono, ishibhile kune-PA66, futhi inephuzu elincibilikayo eliphansi (225°C). I-PA66 inikeza amandla aphakeme, ukumelana nokugqoka okungcono, nendawo yokuncibilika ephakeme (255°C).

Okwesibili, Umehluko Ezimpahleni Zomzimba:

• I-PA66:Iphuzu elincibilikayo: 260-265°C; izinga lokushisa lokushintsha kwengilazi (isimo esomile): 50 ° C; ukuminyana: 1.13–1.16 g/cm³.
• I-PA6:I-semi-transparent noma i-opaque milky-white crystalline polymer pellets; indawo yokuncibilika: 220 ° C; izinga lokushisa lokubola: ngaphezu kuka-310 ° C; ukuminyana okuhlobene: 1.14; ukumuncwa kwamanzi (amahora angama-24 emanzini ku-23°C): 1.8%. Inokumelana okuhle kakhulu kokugqoka kanye nokuzigcoba, amandla aphezulu emishini, ukumelana nokushisa okuhle kanye nezakhiwo zokuvala ugesi, ukusebenza kahle kwezinga lokushisa eliphansi, izakhiwo zokuzicisha, kanye nokumelana namakhemikhali-ikakhulukazi ukumelana nowoyela.

Uma kuqhathaniswa ne-PA66, i-PA6 kulula ukuyicubungula nokubumba, inikeza isicwebezelisi esingcono kakhulu emikhiqizweni eqediwe, futhi inebanga lokushisa elisebenzisekayo elibanzi. Kodwa-ke, inokumunca okuphezulu kwamanzi kanye nokungaqini kahle kwe-dimensional. Ayiqinile kangako, inephuzu elincibilikayo eliphansi, futhi ingasetshenziswa isikhathi eside ezindaweni ezinokhahlo. Igcina ukumelana nengcindezi okuhle phakathi kwebanga lokushisa elibanzi, nezinga lokushisa lesevisi eliqhubekayo elingu-105°C.

Okwesithathu, Unganquma Kanjani Ukuthi Usebenzisa I-PA66 noma I-PA6?
Ukuqhathaniswa kokusebenza phakathi kwe-PA6 ne-PA66:

• Izakhiwo zikamshini: PA66 > PA6
• Ukusebenza okushisayo: PA66 > PA6
• Inani: PA66 > PA6
• Indawo encibilikayo: PA66 > PA6
• Ukumuncwa kwamanzi: PA6 > PA66

Okwesine, Umehluko Kuhlelo Lokusebenza:

• Amapulasitiki wobunjiniyela be-PA6babe namandla aqine kakhulu, ukumelana nomthelela omuhle, ukumelana nokugqokwa okuhle kakhulu, ukumelana namakhemikhali, kanye ne-coefficient ephansi yokungqubuzana. Ngokulungiswa okufana nokuqiniswa kwe-fiber yengilazi, ukugcwaliswa kwamaminerali, noma izithasiselo ze-flame retardant, ukusebenza kwazo kukonke kungathuthukiswa ngokwengeziwe. Zisetshenziswa kakhulu embonini yezimoto kanye nezinkundla zikagesi/zikagesi.
• PA66inokusebenza okuphezulu okuphezulu, okuhlanganisa amandla aphezulu, ukuqina, ukumelana nomthelela, ukumelana nowoyela namakhemikhali, ukumelana nokugqoka, nokuzigcoba ngokwakho. Igqama kakhulu ngobulukhuni, ukuqina, ukumelana nokushisa, nokumelana nokukhasa. Ngenxa yamandla ayo aphezulu uma iqhathaniswa ne-PA6, i-PA66 isetshenziswa kakhulu ezinhlelweni zezimboni ezifana nokukhiqizwa kwezintambo zamasondo.
