I-PA612 yimathiriyeli ye-polymer, igama elipheleleyo yi-polyamide 612, ekwabizwa ngokuba yinayiloni 612. yiplastiki yobunjineli ye-semi-crystalline, eneempawu ezibalaseleyo zomzimba kunye nokuzinza kweekhemikhali.Kwintsimi yobunjineli, i-PA612 isetyenziswa ngokubanzi ekwenzeni iinxalenye kunye namacandelo kwiimoto, umbane, oomatshini kunye namanye amacandelo.

Isakhiwo semolekyuli ye-PA612 yenziwe yi-styrene monomer ngokusebenzisa i-polymerisation yamahhala.Ngexesha lenkqubo ye-polymerisation, i-styrene monomer iqala ingene kwi-rection yasimahla yokongeza ukwenza i-styrene radicals, kwaye ke ezi radicals ziqhubeleka nokukhula kwetsheyini ukuze ekugqibeleni zenze ikhonkco lepolymer.Esi sakhiwo semolekyuli sinikeza i-PA612 iimpawu ezibalaseleyo zoomatshini kunye nokumelana nokunxiba.

Indawo yokunyibilika ye-PA612 liqondo lobushushu apho izinto zitshintsha ukusuka kokuqinileyo ukuya kulwelo.Kwi-PA612, indawo yokunyibilika iphakathi kwama-295-315 degrees Celsius.Indawo yokunyibilika kolu luhlu yenza i-PA612 iplastiki yobunjineli eneemfuno eziphezulu zokushisa.Kwizicelo ezisebenzayo, uluhlu lwendawo yokunyibilika ye-PA612 kufuneka imiselwe ngokwemiqathango ethile yokusetyenzwa kunye nezixhobo.

I-melting point ye-PA612 ichaphazeleka yizinto ezahlukeneyo, kubandakanywa ubunzima be-molecular of material, i-degree of crystallinity, ubukhulu bengqolowa kunye nokunye.Ngokuqhelekileyo, okukhona uphezulu ubunzima bemolekyuli, kokukhona ukuphakama kweqondo lokunyibilika;iphezulu i-crystallinity, isezantsi indawo yokunyibilika;incinci isayizi yeenkozo, iphezulu indawo yokunyibilika.Ngoko ke, uluhlu lwe-melting point ye-PA612 lunokulawulwa ngokulungelelanisa ubunzima bayo be-molecular, i-crystallinity kunye nobukhulu beenkozo kunye nezinye iiparitha.

Kwizicelo ezisebenzayo, uluhlu lwendawo yokunyibilika ye-PA612 yiparamitha ebaluleke kakhulu.Okokuqala, imisela imfuneko yobushushu bokusebenza kwe-PA612.Ukuba indawo yokuncibilika iphantsi kakhulu, inokukhokelela ekunyibilikeni okanye ukubola kwezinto ngexesha lokucubungula;ukuba indawo yokunyibilika iphezulu kakhulu, inokuchaphazela ukusebenza kakuhle kunye nobomi besixhobo.Okwesibini, uluhlu lwamanqaku okunyibilika luchaphazela ukufaneleka kwe-PA612 kwiimeko ezahlukeneyo zesicelo.Ngokomzekelo, iinxalenye ezisetyenziselwa kwiindawo eziphakamileyo zokushisa kufuneka zibe neqondo eliphezulu lokunyibilika ukuze kuqinisekiswe ukuzinza nokuthembeka kwazo kumaqondo obushushu aphezulu.

Ukongeza kwinqanaba lokunyibilika kwayo, i-PA612 inezinye iimpawu ezibalulekileyo zomzimba kunye neekhemikhali.Ngokomzekelo, ibonakaliswe ngamandla amakhulu, ukuqina okuphezulu, ukukhwabanisa okulungileyo kunye nokumelana nokubola.Ukongeza, i-PA612 inokuqhubekeka kakuhle kunye neplastikhi, kwaye inokwenziwa kwaye iveliswe ngeendlela ezahlukeneyo, njengokubumba inaliti kunye nokubumba i-extrusion.

Ukuqukumbela, i-PA612 yimathiriyeli yepolymer esebenza ngokugqwesileyo, kwaye indawo yayo yokunyibilika isuka kwi-295-315 degrees Celsius.Ukulawulwa kolu luhlu kubalulekile ukuqinisekisa ukusebenza kokusetyenzwa kunye nesiphumo sesicelo se-PA612.Ukulawulwa okusebenzayo koluhlu lwe-melting point ye-PA612 lunokufezekiswa ngokukhetha ngokufanelekileyo kunye nokulungelelanisa iiparitha ezifana nobunzima be-molecular, i-crystallinity kunye nobukhulu beenkozo ze-PA612, ukwenzela ukuhlangabezana neemfuno zeemeko ezahlukeneyo zesicelo.
