Indlela yokuchonga ngokuchanekileyo kwaye ukhethe phakathi kwe-PA6 elungisiweyo kunye ne-PA66 (iCandelo loku-1)?

Ngokukhula okukhulayo kobuchwepheshe benayiloni ye-R&D elungisiweyo, umda wesicelo we-PA6 kunye ne-PA66 uye wanda ngokuthe ngcembe. Uninzi lwabavelisi beemveliso zeplastiki okanye abasebenzisi beemveliso zeplastiki zenayiloni abacacanga malunga nomahluko phakathi kwe-PA6 kunye ne-PA66. Ukongeza, kuba akukho mahluko ucacileyo phakathi kwe-PA6 kunye ne-PA66, oku kukhokelele kubhideko olukhulu. Zinokwahlulwa njani i-PA6 kunye ne-PA66, kwaye kufuneka zikhethwe njani?

Okokuqala, Iingcebiso zokuchonga i-PA6 kunye ne-PA66:
Xa utshisiwe, zombini i-PA6 kunye ne-PA66 zikhupha ivumba elifana noboya obutshisiweyo okanye izikhonkwane. I-PA6 ivelisa ilangatye elityheli, ngelixa i-PA66 ivutha ngedangatye eliluhlaza. I-PA6 inokuqina okungcono, inexabiso eliphantsi kune-PA66, kwaye inendawo esezantsi yokunyibilika (225°C). I-PA66 inika amandla aphezulu, ukumelana nokunxiba okungcono, kunye nenqanaba eliphezulu lokunyibilika (255 ° C).

Okwesibini, Umahluko kwiiPropati zoMzi:

• PA66:Indawo yokunyibilika: 260-265 ° C; iqondo lokushisa lokutshintsha kweglasi (imeko eyomileyo): 50 ° C; Ubuninzi: 1.13–1.16 g/cm³.
• PA6:I-semi-transparent okanye i-opaque milky-white crystalline polymer pellets; indawo yokunyibilika: 220 ° C; iqondo lokushisa lokubola: ngaphezu kwe-310 ° C; ukuxinana okuzalanayo: 1.14; ukufunxwa kwamanzi (iiyure ezingama-24 emanzini kwi-23 ° C): 1.8%. Inokumelana nokunxiba okugqwesileyo kunye nokuzithambisa, amandla aphezulu omatshini, ukumelana nobushushu obulungileyo kunye neempawu zokugquma umbane, ukusebenza kakuhle kobushushu obuphantsi, ukucima ukucima, kunye nokumelana neekhemikhali-ingakumbi ukuchasana kweoli.

Xa kuthelekiswa ne-PA66, i-PA6 kulula ukuyiqhuba kunye nokubumba, inika isicwebezelisi esingcono kwiimveliso ezigqityiweyo, kwaye inoluhlu olubanzi lobushushu obusebenzisekayo. Nangona kunjalo, inokufunxeka okuphezulu kwamanzi kunye nozinzo olubi kakhulu. Ayiqinanga kangako, inendawo esezantsi yokunyibilika, kwaye ingasetyenziswa ixesha elide kwindawo ezirhabaxa. Igcina ukuxhathisa okuhle koxinzelelo kuluhlu olubanzi lobushushu, kunye nenkonzo eqhubekayo yobushushu obuyi-105°C.

Okwesithathu, Ungenza Njani Ukugqiba Ukuba Usebenzise I-PA66 okanye I-PA6?
Uthelekiso lokusebenza phakathi kwePA6 kunye nePA66:

• Iipropati zoomatshini: PA66 > PA6
• Ukusebenza kweThermal: PA66 > PA6
• Ixabiso: PA66 > PA6
• Indawo yokunyibilika: PA66 > PA6
• Ukufunxwa kwamanzi: PA6 > PA66

Okwesine, Umahluko kuMda weSicelo:

• PA6 iiplastiki zobunjineliUnamandla aphezulu okuqina, ukuxhathisa okulungileyo, ukuxhathisa okugqwesileyo, ukuxhathisa kweekhemikhali, kunye ne-coefficient ephantsi yokukhuhlana. Ngohlengahlengiso olunjengokuqiniswa kwefayibha yeglasi, ukuzaliswa kweeminerali, okanye izongezo ezibuyisela idangatye, ukusebenza kwazo zonke kunokwandiswa ngakumbi. Zisetyenziswa ikakhulu kwishishini leemoto kunye ne-elektroniki / imimandla yombane.
• PA66inomsebenzi ogqwesileyo jikelele, kubandakanywa amandla aphezulu, ukuqina, ukuxhathisa impembelelo, i-oyile kunye nokumelana neekhemikhali, ukumelana nokunxiba, kunye nokuzithambisa. Igqwesa ngakumbi kubulukhuni, ubulukhuni, ukuxhathisa ubushushu, kunye nokuxhathisa ukukhasa. Ngenxa yamandla ayo aphezulu xa kuthelekiswa ne-PA6, i-PA66 isetyenziswa ngokuqhelekileyo kwizicelo zoshishino ezifana nemveliso yentambo yamatayara.
