Musiyano uripo pakati peNYLON PA6 uye PA66

PA6 uye PAL6 ndeVELOLYAMIde Polymers Ivo vanoshandiswa zvakanyanya nekuda kwekunetseka kwavo kwakanyanya, kuramba kwemakemikari, kupokana kuramba, uye kurema kwechiedza. Kunyangwe paine chete mutsauko mumwe chete pakati peP6 uye pa66, Ndeupi mutsauko mukuita kwavo, uye zvinosarudzwa sei mukushandisa maindasitiri?

PA6 inoumbwa nePolycendenation yeCaprolactam, nepo Pa66 inoumbwa nePolycononsation yeAdipic acid uye hexamfetylenediamine. Kubva pamaonero emorekuru, iwo maviri akafanana chaizvo, saka zvavo zvemuviri uye zvemakemikari zvivakwa zvakafanana. Musiyano ndewekuti hydrogen zvisungo pakati pemamorekuru vePA66 zvakawedzera kusungwa zvakasimba, saka podera yakakwira yakakwira se260 ° C, iyo 20-40 ° C yakakwira kupfuura iyo yePA6. Iyo ine yepamusoro yekupisa kupesana, asi kusimba kwayo uye kupokana kuneta hakuna kunaka seP6. Inzwa kuomarara kwaro neruoko, pa66 kwakaoma kupfuura pa6.

PA6 uye PA6 S60 Siyano

PA6 inowanikwa nemhete-yekuvhura Polymerization yeCaprolactam, nepo Pa66 inowanikwa nePolymer Polymer yeHolymer yeHolymerylediamine uye Adipic acid. Iwo maviri ane zvakafanana molecular formula, asi chimiro chakasiyana chaizvo. Nhamba yeHydrogen zvisungo zveP66 yakakwira kupfuura iyo yePA6, uye isimba reMorecular rinewo kune iyo pa6, saka pa66 ine tembiriti iri nani uye inoda kupisa kwakanyanya.

Kuomarara kweP66 ndeye 12% yakasimba kupfuura iyo yePA6. Kubva pamaonero emuti mumwe chete, pa6 ane kuomarara kuri nani, uye pa66 ane kuomarara. Izvi ndizvo chaizvo nekuda kweiyo moleky chimiro. inokonzerwa neakasiyana hydrogen zvisungo.

PA6 uye PA6 SEASE SERPELING

Iyo yekunyunguduka ye pa6 ndeye 220 ° C, uye yekunyunguduka iri makumi maviri nemashanu Zviri nyore kuita, ine simba rakakwirira kwazvo, kukanganisa kupokana, kuramba kwemakemikari, kuzvishingisa, kuzvishingisa kwezvinhu zvakaderera, uye kupokana kwakaderera kwemafuta kuri nani pane pa66. Iyo ine yakanaka nzvimbo gloss, yakanakisa tembiricha yekushandisa, yekuzvidzivirira, yekudzima tembiricha, inogona kushandiswa kwenguva yakareba mumamiriro ezvinhu akaomesesa, uye inogona kuchiramba ichikwana kushushikana kwakakwana mukushandiswa kwenguva refu kwekushandisa kwenguva refu. Nekudaro, kana zvichienzaniswa ne pa66, pa6 ine mvura yepamusoro yemvura, saka kugadzikana kwayo kwakadzika kune varombo. Iko kushandiswa kwePA6 kuchaitawo zvakaringana kuita nekuwedzera girazi fiber, mineral shanduko uye kuwedzera murazvo retare.

Iyo yekunyungudika point ye pa66 ndeye 260 ° C, uye yekunyungudika ndeye 260 ° C (275 ° C: Tembiricha yekunyungudika haifanire kunge yakakwira kupfuura 300 ° C), uye murazvo uri bhuruu kana ichipisa. Iine simba rakakura uye kuomarara, kuramba kwakanaka, kuramba mafuta, kupokana nekupokana, kuramba zvinhu zvemakemikari, kuomarara, kuomarara, kupokana nekupokana uye kupokana nekukanda zviri nani.

Kuoma

Pa6 ane mvura yakakwira yekubvisa, saka kutarisisa kunofanirwa kubhadharwa kune kuomesa kwaro usati wagadziriswa. Midziyo yekuchengetedza yezvinhu inoda kuve nguva yekugara. Kana iyo humidity iri> 0.2%, inokurudzirwa kuomesa mumhepo inopisa yakaoma pamusoro 80 ° C kwe34 maawa. Kana zvinyorwa zvacho zvakaratidzwa nemhepo kweanopfuura maawa masere, zvinokurudzirwa kuti zviome pakudziya kwe10 ° C. Ita vacuum kuoma kweanopfuura 1 ~ maawa maviri.

Pa66 haidi kuomeswa kana zvinyorwa zvakaiswa chisimbiso uye chichengetwa. Kana mudziyo wekuchengetedza wakavhurwa, unokurudzirwa kuti uome mumhepo inopisa yakaoma pa85 ° C. Kana iyo humidity yakakura kupfuura 0.2%, inoda kuve yekuvhara yakaomeswa pa105 ° C ye 1 ~ maawa maviri. .

· Mold tembiricha

PA6: 80 ~ 90 ℃. Moly tembiricha inokanganisa zvakanyanya crystallinity, iyo ichikanganisa manhamba emakwenzi epurasitiki zvikamu.

Zvikamu zvakatetepa-chakakomberedzwa epurasitiki nehuremu hwakareba, hunokurudzirwa kushandisa tembiricha yakakwira. Kuwedzera tembiricha yemukati kunogona kuwedzera simba uye kuomarara kwepurasitiki chikamu, asi kuchaderedzawo kuomeswa kwayo maererano. Kana kurira kwemadziro kwakakura kupfuura 3mm, kunokurudzirwa kushandisa tembiricha yakaderera pa20 ~ 40 ° C, uye kune yakasimbiswa-yakasimbiswa zvinhu, iyo tembiricha yakaumbwa inofanira kunge yakakura kupfuura 80 ° C.

Pa66: 80 ° C inokurudzirwa. Mol Tembiricha inokanganisa iyo degree rekristunity iyo inozokanganisa zvivakwa zvechigadzirwa.

Zvezvikamu zvakatetepa-mapurasitiki emapurasitiki, kana iyo molity tembiricha yakaderera kupfuura 40 ° C, iyo crystallinity yepurasitiki chikamu ichachinja nenguva. Kuti uchengetedze kugadzikana kwe geometric kugadzikana kwepurasitiki, kurapwa kunodiwa kunodiwawo.

PA6 inoshandiswa muminda yeindasitiri yakadai semagetsi uye mota. Indasitiri yayo yevagari vemo inodya yakanyanya kuenzana neyanylon filing yejira, anenge 58%. Iko kushandiswa kwePA6 mumugwagwa weTire Nyoni yeMusika maakaunzi kweanenge 13%. Injiniya Purasitiki Shandisa Pa6 Akaverengerwa ye12%, kusanganisira jekiseni epurasitiki uye dzakasarudzika mapurasitiki. Pa6 maakaunti kweanenge 6% yehove yekuredza waya. Plastiki firimu-giredhi pa6 yekugadzirwa kweBoo Mafirimu maApple account ye4%, STPLE FIBER PASTABLCE matepi, etc. maakaundi 3%.

Pa66 inoshandiswa zvakanyanya muzvipfeko, kushongedza, mainjiniya mapurasitiki uye mamwe minda. Chikamu chepamusoro chekushandiswa kwayo ndeyako mapurasitiki mapurasitiki, accounting 65% yehuwandu hwekushandisa, nepo maindasitiri ekusvika e20%, uye vamwe account ye15% ye15% yekunyorwa kwakazara. Zvigadzirwa zvekusununguka kwe pa66 zvinonyanya kutaurwa muinjiniya mapurasitiki, izvo zvisina kukodzera kupuruzira nekuda kwekuwedzera kwavo kwakaomarara uye kusakwana kwavo.
