Umahluko phakathi kwe-nylon pa6 kunye ne-PA66

I-PA6 kunye ne-PA66 zombini i-polyamide polymers (yaziwa njenge-NYLOLO), zombini ezo zithuthunga okanye zimhlophe ngembonakalo. Basetyenziswa ngokubanzi ngenxa yobunzima babo obuhle, ukumelana nemichiza, ukumelana nokungakhathali, kunye nobunzima bokukhanya. Nangona inye kuphela umahluko phakathi kwe-PA6 kunye ne-PA66, yintoni umahluko kwintsebenzo yabo, kwaye kufanele ukuba zikhethwe njani kwizicelo zemveliso?

I-PA6 yenziwa yi-Polyconditionation ye-caprolactam, ngelixa i-PA66 yenziwa yi-Polycontition ye-Adipic Acid kunye ne-hexmethylinedine. Ukusuka kwimozulu yemolekyuli yembono, ezi zimbini ziyafana, ke iipropathi zabo zomzimba kunye neekhemikhali ziyafana. Umahluko kukuba iimbovu ze-hydrogen phakathi kwe-PA66 zibotshwe ngokuqinileyo, ke indawo yayo yokunyibilika iphakame ingama-260 ° C, eyi-20 ukuya kwengama-20 ukuya kwengama-4 ukuya kwengama-20. Ilunyange ubutshijolo obalaseleyo, kodwa ukumelana nokudinwa kwayo akulunganga njenge-PA6. Yiva ubunzima bayo obunzima ngesandla, i-PA66 inzima kune-PA6.

I-PA6 kunye ne-PA66 yesakhiwo

I-PA6 ifunyanwa yi-Polymering ye-caprolactam, ngelixa i-PA66 ifunyanwa yi-prosancence Polymer ye-Hexalmerlinedine kunye ne-Adipic Acid. Zombini zinefomula yemolekyuli efanayo, kodwa isakhiwo sahluke ngokupheleleyo. Inani leembophelelo ze-HYDRONG ze-PA66 zingaphezulu kwe-PA6, kwaye amandla eemolekyuli nawo anamandla kunaleyo ye-PA6, ke i-PA66 inepropathi engcono ye-thermal kwaye ifuna ubushushu obuphezulu.

Ubulukhuni be-PA66 yi-12% yomelele kunaleyo ye-PA6. Ukusuka kwimbono yefayibha enye, i-PA6 inobunzima obungcono, kwaye i-PA66 inobungqola obungcono. Oku ngokuchanekileyo ngenxa yesakhiwo seemolekyuli. ibangelwa ziibhondi ezahlukeneyo ze-hydrogen.

I-PA6 kunye ne-PA66 yentsebenzo

Indawo yokunyibilika ye-PA6 inyibilika engama-220 ° C, kunye nobushushu obunyibilikayo ngama-230 ~ 48 ° 2 ° 2 ° 4 280 ° 4 280 ° 40 ° 4 Kulula ukuqhubekeka, inamandla amakhulu e-sund, ukuxhathisa kwempembelelo, ukuxhathisa impatho yokuthintela, ukunganyangeki kwamachiza, kunye nokuchasa i-ofisi ephantsi kunye nokuchasana kweoyile kungcono kune-PA66. Inomhlaba ofanelekileyo wegloss, ukusebenza kweqondo lobushushu oluphantsi, ukucima ubushushu, kusetyenziswa ixesha elide phantsi kweemeko ezinzima, kwaye zisenokugcina uxinzelelo lwaneleyo kuluhlu lwamaqondo obushushu kangako. Nangona kunjalo, xa kuthelekiswa ne-PA66, i-PA6 inezinga eliphezulu lokufumana amanzi, ke ukuzinza kwayo kuhlwempuzekile. Ukusetyenziswa kwe-PA6 kuya kuba nengqungquthela ebaluleke ngakumbi ngokongeza i-fiber yeglasi, ukulungiswa kweminerali kunye nokongezwa kwelangatye.

Inqaku lokunyibilika kwe-PA66 li-260 ~ 265 ° C, kunye nobushushu obunyibilikayo ngama-260 ~ 40 ° C (275 ° 4 280 ° 400 ° 400 ° C), kunye nelangatye Iblue xa ivutha. It has high strength and rigidity, good impact resistance, oil resistance, wear resistance, chemical resistance and self-lubricating property, and its hardness, rigidity, heat resistance and creep resistance are better.

I-PA6 kunye ne-PA66 yenkqubo

·O · kwamehlo

I-PA6 inenqanaba eliphezulu lokufumana amanzi, ke kufuneka kuthathelwe ingqalelo eyomileyo ngaphambi kokuqhutywa. Isikhongozeli sokugcina izinto kufuneka sibe nomoya. Ukuba umswakama ngu-0,2%, kuyacetyiswa ukuba yome umoya owomileyo owomileyo ngaphezulu kwe-80 ° C kwiyure ezi-3-4. Ukuba izinto ezibonakalayo ziveze umoya ngaphezulu kweeyure ezi-8, kuyacetyiswa ukuba wome kwiqondo lobushushu le-105 ° C. Yenza i-vacuum yomile ngaphezulu kwe-1 ~ 2 iiyure.

I-PA66 akufuneki yomiswe ukuba loo nto itywinwe kwaye igcinwe. Ukuba isikhongozelo sogcino sivuliwe, kuyacetyiswa ukuba soyime ngomoya ovuthayo owomileyo nge-85 ° C. Ukuba umswakama ungaphezulu kwe-0.2%, kufuneka ilomiswe i-vacuum eyomileyo kwi-105 ° C kwi-1 ~ 2 iiyure. .

Iqondo lobushushu elinesondo

I-PA6: 80 ~ 90 ℃. Iqondo lobushushu elichaphazela kakhulu i-crystallinity, elichaphazela iipropathi zoomatshini bezinto zeplastiki.

Kwiinxalenye zeplastiki ezinqatyisiweyo enenkqubo ende, kuyacetyiswa ukuba isebenzise iqondo lobushushu obuphezulu. Ukonyusa amaqondo obushushu omnyama anokongeza amandla kunye nobungqola benxalenye yeplastiki, kodwa iya kunciphisa kakhulu ubunzima bayo ngokufanelekileyo. Ukuba ubukhulu becala bungaphezulu kwe-3mm, kucetyiswa ukuba basebenzise ubushushu obuphantsi kwi-20 ° 40 ° 8 ° C, kunye nezixhobo eziqinileyo zeglasi, amaqondo obunqandi kufuneka abe ngaphezulu kwe-80 ° C.

Pa66: I-80 ° C iyacetyiswa. Amaqondo obushushu abumba aya kuchaphazela inqanaba le-crystallies eliza kuchaphazela ubume bemveliso yemveliso.

Kwiinxalenye zeplastiki ezinqatyisiweyo, ukuba iqondo lobushushu elicekeceke, ukuba amaqondo obushushu anqabileyo asezantsi kune-40 ° C, i-crystallies yenxalenye yeplastiki iya kutshintsha kunye nexesha. Ukuze ugcine uzinzo lwejometri yenxalenye yeplastiki, impatho yonyango iyafuneka.

I-PA6 kunye ne-PA66

I-PA6 isetyenziswa kwimimandla yemizi-mveliso efana ne-elektroniki kunye neemoto. Umzi-mveliso wayo waseburhulumenteni usebenzisa umda ophezulu we-nylon Filament yempahla, malunga ne-58%. Ukusetyenziswa kwe-PA6 kwi-Poira kwi-Innon yeNtengiso yeNtengiso ye-NYLOLO i-13%. IPlasticary Plastics Sebenzisa i-PA6 inikwe i-12%, kubandakanya nenaliti yeplastiki kunye neplastiki eziguqulweyo. Iiakhawunti ze-PA6 malunga ne-6% ye-wire yomnxeba. I-PATA6 yePlasi yeFempey yeFempey yeFet yeWindows Iitephu, njl njl.

I-PA66 isetyenziswa ngokubanzi kwimpahla yokunxiba, umhombiso, iplasitiki yobunjineli kunye namanye amasimi. Eyona nto iphakamileyo yokusebenzisa iplasitiki yobunjineli, i-accounting ye-65% yokusebenzisa itotali, ngelixa i-akhawunti yemizi-mveliso ye-20%, kunye ne-akhawunti ye-15% yokusebenzisa i-15% yokusebenzisa i-15% yokusebenzisa i-15% yokusebenzisa i-15% yokufumana i-15% yokusebenzisa i-15% yokufumana i-15% yokusebenzisa i-15% yokusebenzisa i-15% yokusebenzisa i-15% yokufumana i-15% yokusebenzisa i-15% yokusebenzisa i-15% yokusebenzisa i-15% yokusebenzisa i-15% yokufumana i-15% yokusebenzisa i-15% yokusebenzisa ngokupheleleyo. Iimveliso ze-DOWHEAM ze-PA66 zigxile kakhulu kubunjineli beeplanga, ezingalunganga zokujikeleza ngenxa yengqongqo yazo kunye nobunzima obungapheliyo.
