Ungayichonga njani nokukhetha ngokuchanekileyo phakathi kwe-PA6 eguquliweyo kunye ne-PA66 (Icandelo 1)?

Ungayichonga njani nokukhetha ngokuchanekileyo phakathi kwe-PA6 eguquliweyo kunye ne-PA66 (Icandelo 1)?

Ngokukhula kokukhula kwetekhnoloji ye-R&D ye-nylon eguquliweyo, ububanzi bokusetyenziswa kwe-PA6 kunye ne-PA66 buye banda kancinci kancinci. Abavelisi abaninzi bemveliso yeplastiki okanye abasebenzisi beemveliso zeplastiki ye-nylon abacaci ngomahluko phakathi kwe-PA6 kunye ne-PA66. Ukongeza, ekubeni kungekho mahluko abonakalayo phakathi kwe-PA6 kunye ne-PA66, oku kukhokelele ekudidekeni okukhulu. Ingahlulwa njani i-PA6 kunye ne-PA66, kwaye kufuneka zikhethwe njani?

Okokuqala, Iingcebiso Zokuchonga i-PA6 kunye ne-PA66:
Xa itshisiwe, zombini i-PA6 kunye ne-PA66 zikhupha ivumba elifana neloboya okanye iinzipho ezitshisiweyo. I-PA6 ivelisa ilangabi elityheli, ngelixa i-PA66 itsha ngelangabi eliluhlaza okwesibhakabhaka. I-PA6 inokuqina okungcono, ixabisa kancinci kune-PA66, kwaye ineqondo lokunyibilika eliphantsi (225°C). I-PA66 inika amandla aphezulu, ukumelana nokuguguleka okungcono, kunye neqondo lokunyibilika eliphezulu (255°C).

Okwesibini, Umahluko kwiipropati zomzimba:

• I-PA66:Iqondo lokunyibilika: 260–265°C; ubushushu bokutshintsha kweglasi (imeko eyomileyo): 50°C; uxinano: 1.13–1.16 g/cm³.
• I-PA6:Iipellets zepolymer zekristale ezinombala omhlophe okanye okhanyayo; iqondo lokunyibilika: 220°C; ubushushu bokubola: ngaphezulu kwama-310°C; uxinano: 1.14; ukufunxwa kwamanzi (iiyure ezingama-24 emanzini kwi-23°C): 1.8%. Inokumelana nokuguguleka okuhle kakhulu kunye nokuzithambisa, amandla aphezulu oomatshini, ukumelana nobushushu kunye neempawu zokugquma umbane, ukusebenza kakuhle kobushushu obuphantsi, iimpawu zokuzicima, kunye nokumelana neekhemikhali—ingakumbi ukumelana neoyile.

Xa ithelekiswa ne-PA66, i-PA6 kulula ukuyicubungula nokuyibumba, inika ukukhanya okungcono kumphezulu kwiimveliso ezigqityiweyo, kwaye inomgangatho wobushushu obanzi osebenzisekayo. Nangona kunjalo, inokufunxwa kwamanzi okuphezulu kunye nozinzo oluphantsi. Ayiqini kangako, inendawo yokunyibilika ephantsi, kwaye ingasetyenziswa ixesha elide kwiindawo ezinzima. Igcina ukumelana okuhle noxinzelelo kumanqanaba obushushu abanzi, kunye nobushushu obuqhubekayo benkonzo obuyi-105°C.

Okwesithathu, Ungasigqiba Njani Ukuba Usebenzise i-PA66 okanye i-PA6?
Uthelekiso lokusebenza phakathi kwe-PA6 kunye ne-PA66:

• Iimpawu zoomatshini: PA66 > PA6
• Ukusebenza kobushushu: PA66 > PA6
• Ixabiso: PA66 > PA6
• Indawo yokunyibilika: PA66 > PA6
• Ukufunxwa kwamanzi: PA6 > PA66

Okwesine, Umahluko kwiSikhundla soSetyenziso:

• Iiplastiki zobunjineli ze-PA6zinamandla aphezulu okutsalwa, ukumelana nempembelelo elungileyo, ukumelana nokuguguleka okugqwesileyo, ukumelana neekhemikhali, kunye ne-coefficient ephantsi yokungqubana. Ngotshintsho olufana nokuqinisa ifayibha yeglasi, ukuzaliswa kwezimbiwa, okanye izongezo ezithintela ilangatye, ukusebenza kwazo ngokubanzi kunokuphuculwa ngakumbi. Zisetyenziswa kakhulu kwishishini leemoto nakwiindawo ze-elektroniki/zombane.
• I-PA66Isebenza kakuhle kakhulu xa iyonke, kuquka amandla aphezulu, ukuqina, ukumelana nefuthe, ukumelana neoyile kunye neekhemikhali, ukumelana nokuguguleka, kunye nokuzithambisa. Igqwesa ngakumbi kubunzima, ukuqina, ukumelana nobushushu, kunye nokumelana nokurhubuluza. Ngenxa yamandla ayo aphezulu xa ithelekiswa ne-PA6, i-PA66 isetyenziswa kakhulu kwizicelo zoshishino ezifana nokuvelisa iintambo zamatayara.
