Ubunjiniyela bePulasitiki: Umehluko wephepha le-PA6 Sheet PA66 Sheet

1. Ingemuva:

I-PA Material, i-polyamide noma evame ukubizwa ngokuthi yi-nylon, iyenziwa nge-ensinger ngokwezimo ezijwayelekile zesitoko ukuze ishebhisi eshidini, induku neshubhu ingenye yepulasitiki evamile yobunjiniyela. Inezinhlobo ezi-2 zezinto ezibonakalayo, i-PA6 ne-PA66, okuyizinto zeylon ezivame kakhulu. Lezi zinhlaka ezimbili ziyafana futhi zinezinto eziningi ezifanayo. Manje umehluko phakathi kwalokhu okubili?

I-PA66 ifakwe ngempumelelo i-polymer ibe yi-polymer nge-polymer ngoWallace Hume Carothers ngo-1935

I-PA6 i-POSMERS i-POSMERS eyenziwe nguJalimane iG Scraker isebenzisa i-caplolactam eyodwa njengezinto ezingavuthiwe kwezinto eziluhlaza ε-Aminocaproic acid njengoMuTiator. Ukukhiqizwa kokuhlolwa kwe-PA6 fiber kwenziwa ngo-1939, futhi ukuhwebelana kwenziwa yinkampani yaseJalimane uFaben ngo-1943.

2. Isakhiwo:

Ukuze sihlaziye umehluko phakathi kwabo, kufanele siqale ngesakhiwo sabo. Njengoba sonke sazi, i-PA6 yakhiwa nge-polymerization yendabuko ye-caplolactam, futhi i-nylon pa66 itholakala ngokubuyiselwa kwe-hexamethylediane nge-adipic acid. I-PA6 ne-PA66 inefomula efanayo yamangqamuzana, kepha ifomula lezinhlelo lihlukile, njengoba kukhonjisiwe kulokhu okulandelayo:

Yingenxa yalo mehluko ukuthi uhlobo umehluko, njengamandla e-hydmolecular hydrogen bonding ahlukile.

3. Ukusebenza

Iphoyinti lokuncibilika le-PA66 lingu-260 ~ 265 ° C, kanye nokushisa kwengilazi (isimo esomile) kungu-50 ° C. Ubukhulu bungu-1.13 ~ 1.16 g / cm3.

I-PA6 Translucent noma i-Opaque Milky Crystalline Polymer Polymer, iphuzu elincibilikayo 220 ° C, izinga lokushisa elivuthayo likhulu ngaphezu kwama-310 ° C, ukumuncwa kwamanzi (ama-24 ° C amanzi angama-24 amahora angu-1,8%) Inamandla aphezulu emishini, ukumelana nokushisa okuhle kanye nezakhiwo zokufakwa kukagesi, ukusebenza okuhle kakhulu kwezinga lokushisa, ukuqina kokuziqhelelanisa okuhle nokuziqhelelanisa nokuziqhenya kwamakhemikhali, ikakhulukazi ukumelana kwamakhemikhali.

Uma kuqhathaniswa ne-PA66, i-PA6 kulula ukuyicubungula kanye nefomu, inesicwebezelisi esihle ebusweni bomkhiqizo, futhi inebanga lokushisa elibanzi, kepha linezinga eliphakeme lokufakwa kwamanzi kanye nokuqina kobukhulu obukhulu. Inobuqili obuphansi, iphuzu eliphansi elincibilikayo, ukusetshenziswa kwesikhathi eside ezindaweni ezinokhahlo, nokuxineka okwanele ebangeni lokushisa elibanzi. Ukushisa okuqhubekayo kokusebenzisa kungu-105 ° C.

Sekukonke, ukungezwani kokusebenza phakathi kwe-PA66 ne-PA6 kungokulandelayo:

Izimo zenqubo

Ukomisa Ukwelashwa

I-PA6 ithola umswakama kalula, ngakho-ke ukunakwa okukhethekile kufanele kukhokhelwe ukomisa ngaphambi kokucutshungulwa. Uma okuqukethwe kuhlinzekwa ngezinto ezingavunyelwe amanzi, isitsha kufanele sivalwe. Uma umswakama mkhulu kune-0.2%, kunconywa ukomisa emoyeni owomile oshisayo ngaphezulu kwama-80 ° C amahora ama-3-4. Uma okuqukethwe kuvezwe emoyeni amahora angaphezu kuka-8, kunconywa ukomisa ngo-105 ° C isikhathi esingaphezu kwamahora ayi-1 kuye kwayi-2. Kungcono ukusebenzisa owomisa owomile.

I-PA66 Uma okuqukethwe kuvalwe uphawu ngaphambi kokucutshungulwa, khona-ke asikho isidingo sokoma. Uma kuvulwa isitsha sesitoreji, kunconywa ukoma emoyeni oshisayo, owomile ku-85 ° C. Uma umswakama mkhulu kune-0.2%, kuyadingeka futhi ukufeza ukomisa i-vacuum ku-105 ° C amahora 1 kuya kwayi-2. Kungcono ukusebenzisa owomisa owomile. Ukushisa kokubumba: 260 ~ 310 ° C, 280 ~ 320 ° C ngezinhlobo ezithuthukisiwe.

Izinga lokushisa le-Main

I-PA6: 80 ~ 90 ° C. Ukushisa okulindile kuthinta kakhulu i-crystaltaltity, yona ethinta izakhiwo zemishini zale ngxenye.

Ezingxenyeni eziyishumi nambili ezinadongeni, ezigeleza isikhathi eside, kuyanconywa futhi ukufaka amazinga okushisa aphezulu wokubumba. Ukwandisa izinga lokushisa okubumba kwandisa amandla nokuqina kwengxenye, kepha kunciphisa ubulukhuni. Uma ubukhulu bodonga bukhulu kune-3mm, kunconywa ukusebenzisa isikhunta sokushisa esiphansi se-20 ~ 40 ° C. Ukuqiniswa kwengilazi Ukushisa okulindayo kufanele kube kukhulu kune-80 ° C.

Kunconywa i-PA66: 80 ° C iyanconywa. Ukushisa okubumba kuzothinta i-crystaltaltity, ezothinta izakhiwo zomkhiqizo.

Ezingxenyeni zepulasitiki ezidongeni elincanyana, uma izinga lokushisa le-main lisezingeni eliphansi kune-40 ° C

Ukulimala kokuncibilika

I-PA6: 230 ° Ch, 250 ~ 280 ° C ngezinhlobo ezithuthukisiwe.

I-PA66: 260 ~ 290 ° C. Umkhiqizo wezithasiselo zengilazi engu-275 ~ 280 ° C. Ukushisa okuncibilikayo kufanele kugwenywe ngenhla kwama-300 ° C.

Ingcindezi yomjovo

Zombili ngokuvamile ziphakathi kuka-750 no-1250 Bar (kuya ngentokozo kanye nomklamo womkhiqizo).

Isivinini somlingo

Zombili ziyisivinini esikhulu (ziphansi kancane ngezinto eziqinisiwe).

Umgijimi nesango

Njengoba isikhathi sokusetha i-PA6 ne-PA66 sifushane kakhulu, isikhundla sesango libaluleke kakhulu. Ukugcotshwa kwesango akufanele kube ngaphansi kuka-0.5 * t (lapho t ubukhulu bengxenye yepulasitiki). Uma kusetshenziswa umgijimi oshisayo, usayizi wesango kufanele ube mncane kunomgijimi ojwayelekile ngoba umgijimi oshisayo angasiza ukuvikela ukuqina kwangaphambi kwesikhathi. Uma kusetshenziswa isango elingaphansi, ububanzi obuncane besango kufanele kube ngu-0.75 mm.

5. Isicelo

I-PA6 Engineering Plastics inamandla aphezulu ashubile, ukumelana nomthelela omuhle, ukumelana kahle kokugqoka okuhle, ukumelana kwamakhemikhali kanye nokungqubuzana okuphansi kwenhlamvu. Zingashintshwa nge-fiber ye-glass, ukuguqulwa kwamaminerali kanye ne-flame retardant. Kwenza kube nzima kakhulu, ikakhulukazi okusetshenziswa embonini yezimoto kanye nemishini ye-elekthronikhi.

I-PA66 inokusebenza okuhle okuhle, amandla aphezulu, ukuqina okuhle, ukumelana nomthelela, ukumelana kwamafutha kanye nokumelana nokuzithambisa, ukumelana nokushisa, ukumelana nokushisa. I-PA66 isetshenziselwa kakhudlwana ukukhiqizwa kwezintambo zezimboni ezifana nezintambo ngenxa yamandla aphezulu kune-PA6.

I-PA6 ne-PA66 yeqa izinhlelo zokusebenza eziningi, kepha lapho i-PA6 ingasetshenziswa khona, i-PA66 ngokuvamile ayisetshenziswa.
