Injiniya Purasitiki: Musiyano wePA6 Sheet Pa66 Sheet

1. kumashure:

Pa Chinyorwa, puramba kana kuwanzonzi nylon, inogadzirwa neEnsinger mu Standinger Stock maumbirwo emachina muhomwe, tsvimbo uye tube ndeimwe yemapuranga echijini. Iyo ine marudzi maviri ezvinyorwa, pa6 naP66, ndeipi inonyanya kujairika nylon zvinhu. Zvimiro zviviri zvakafanana zvakafanana uye zvine zvakawanda zvinhu zvakafanana. Saka chii musiyano uripo pakati pezviviri?

Pa66 wakabudirira polymerized muP66 Polymer naWilLay Hume Cariters muna 1935. Kugadzira Spinning kubva muna 1936 kusvika 1937, uye yaive yekutengeserana neCuftent muUnited States pakupera kwa1939.

PA6 IS PA6 Polymer yakanyorwa neGerman IG SCHERS uchishandisa imwe caprolactam seyakaisa zvinhu qu-aminoca procroc acid seyekuproic singone. Kugadzirwa kwekuedzwa kwePa6 fiber kwakaitwa muna 1939, uye kutengeserana kwakaitwa nekambani yeGerman Faben muna 1943.

2. Chimiro:

Kuongorora mutsauko pakati pavo, isu tinofanirwa kutanga nechimiro chavo. Sezvo isu tese tinoziva, pa6 inoumbwa nehingi-yekuvhura Polymerization yeCaprolactam, uye Nylon Pa66 inowanikwa neCrewamethyle yeHexMethyle Seigine neAdipic acid. PA6 ne pa66 vane zvakafanana molecular formula, asi fomu yekugadzira yakasiyana, sezvakaratidzwa mune inotevera nhamba:

Izvo chaizvo nekuda kwemusiyano uyu kuti chimiro chemusiyano, chakadai seyenzi yekubatanidza hydrogen yekubatanidza simba rakasiyana.

3. Performance

Iyo yekunyungudika point ye pa66 ndeye 260 ~ 265 ° C, uye girazi rinoshandura tembiricha (yakaoma mamiriro) ndeye 50 ° C. Iyo density ndeye 1.13 ~ 1.16 g / cm3.

PA6 Translucent kana opaque Milky Crystalline Polymer Scolmer Scolmer ine simba rakakwirira simba, rakanakisa kupisa uye magetsi ekusimbisa zvinhu, zvakanakisa tembiricha, zvakanakisa kudzima uye kurwisa kwemakemikari, kunyanya kuramba kwakanaka kwazvo.

Kuenzaniswa ne pa66, pa6 iri nyore kugadzirisa uye fomu, ine gloss yakanaka pamusoro pechigadzirwa, uye ine huwandu hwakawanda hwekudziya, asi une mvura yakakwira yekudzora uye isina kurongeka kudzikama. Iyo ine yakaderera kuomarara, yakaderera yekunyungudza pfungwa, kushandiswa kwenguva refu munzvimbo dzine hutsinye, uye kushushikana kwakakwana mune yakasarudzika tembiricha. Iyo inoenderera ichishandisa tembiricha ndeye 105 ° C.

Zvakazara, mutsauko wekuita pakati pe pa66 uye pa6 ndizvo zvinotevera:

Mechanical Properties: Pa66> PA6

Kupisa Medium Performance: Pa66> PA6

Mutengo: Pa66> PA6

Inline point: Pa66> PA6

Mvura inobata: Pa66 <PA6

Kubata Kwemamiriro ekunze: Pa66 <PA6

Nguva yekudzungaira: PA60 <PA6

Kuumbwa Performance: Pa66 <PA6

4.Mamiriro ekugadzirisa

Kupukuta kurapwa

PA6 inobata unyoro nyore, saka kutarisirwa kwakakosha kunofanirwa kubhadharwa kuti uome usati wagadzirisa. Kana izvo zvinyorwa zvichipiwa mune zvemvura zvinhu, mudziyo unofanira kuchengetwa wakavharwa. Kana iyo humidity yakakura kupfuura 0.2%, inokurudzirwa kuoma mumhepo inopisa yakaoma pamusoro 80 ° C kwe 3-4 maawa. Kana zvinyorwa zvave zvichinzi mhepo kweanopfuura maawa masere, zvinokurudzirwa kuoma pa105 ° C kweanopfuura 1 maawa maviri kusvika maviri. Zvakanaka kushandisa dhizaini yakaoma yakaoma.

Pa66 kana izvo zvinyorwa zvakaiswa chisimbiso usati wagadziriswa, saka hapana chikonzero chekuoma. Kana mudziyo wekuchengetedza wakavhurwa, unokurudzirwa kuomesa mumhepo inopisa, yakaoma yakaoma pa 85 ° C. Kana iyo humidity yakakura kupfuura 0.2%, zvinodikanwa kuti utarise vacuum kuoma pa105 ° C kwe1 kusvika maawa maviri kusvika maviri. Zvakanaka kushandisa dhizaini yakaoma yakaoma. Kuumbisa tembiricha: 260 ~ 310 ° C, 280 ~ 320 ° C yeiyo yakawedzerwa mhando.

Mol Tembiricha

PA6: 80 ~ 90 c. Iyo inopisa tembiricha inokanganisa zvakanyanya crystallinity, iyo inokanganisa michero yekuchinjika kwechikamu.

Zvikamu zvakatetepa, zvakapfuura, zvinokurudzirwa zvakare kushandisa tembiricha yakakwira yekupisa. Kuwedzera tembiricha yakaumbwa kunowedzera simba uye kusimudzwa kwechikamu, asi kunoderedza kuoma. Kana madziro akakora akakurisa kupfuura 3mm, anokurudzirwa kushandisa tembiricha yakadzika mold ye20 ~ 40 ° C. Kune girazi kusimbiswa kwekunyomba tembiricha kunofanirwa kuve kwakakura kupfuura 80 ° c.

Pa66: 80 ° C inokurudzirwa. Iyo tembiricha inopisa ichakanganisa crystallinity, iyo ichakanganisa zvivakwa zvemuviri zvechigadzirwa.

Zvezvikamu zvakatetepa zvepurasitiki.

Kupisa tembiricha

PA6: 230 ~ 280 ° C, 250 ~ 280 ° C yeiyo yakasimudzwa mhando.

Pa66: 260 ~ 290 ° C. Chigadzirwa chegirazi yekuwedzera ndeye 275 ~ 280 ° C. Tembiricha yekunyungudika inofanira kudzivirirwa kupfuura mazana matatu ° c.

Kumanikidza Kumanikidza

Zvese zviri zviviri zviri pakati pe750 ne1250 bar (zvichienderana nezvinhu uye zvigadzirwa zvigadzirwa).

Inomhanyisa jekiseni

Ose ari maviri akanyanya kumhanya (zvishoma pasi pezvinhu zvakasimbiswa).

Mumhanyi neGedhi

Sezvo nguva yekugara yePA6 ne pa66 ipfupi, chinzvimbo chegedhi chakakosha. Iyo gedhi kupatsanurwa hakufanirwe kunge kushoma pane 0.5 * t (uko t (uko t (kupi t ndeyekukora kwepurasitiki chikamu). Kana mumhanyi anopisa anoshandiswa, saizi saizi dzinofanira kunge diki pane nemumhanyi wenguva dzose nekuti mumhanyi anopisa anogona kubatsira kudzivirira kusimbisa kwekutanga kwezvinyorwa. Kana gedhi rakazara rinoshandiswa, iyo shoma svutugadzike yegedhi inofanira kunge iri 0.75 mm.

5. application

Pa6 engineering mapurasitiki ane simba rakakwirira simba, rakanaka kukanganisika, rakakora kupfeka kurwisa, kurwisa kwemakemikari uye kupokana kwakaderera. Vanogona kuchinjwa negirazi fiber, mineral filer suflation uye murazvo unodzoreredza. Inoita kuti ive yakazara yakazara, inonyanya kushandiswa muindasitiri yemotokari uye zvishandiso zvemagetsi.

Pa66 ine simba rakanaka rakazara, simba rakanyanya, kuomarara, kurwisa, kupokana nekuzvishingisa, kunyanya kuomarara, kuomesa, kupisa, kupisa kupokana uye kuita kwekutyaira. Pa66 inoshandiswa zvakanyanya pakugadzirwa kweinisitiri yarns senge tambo nekuda kwesimba rayo rakakwirira kupfuura pa6.

PA6 uye PAL6 inodarika mune dzakawanda mashandisirwo, asi apo pa6 inogona kushandiswa, pa6 kazhinji hazviwanzo kushandiswa.

Ahd plastiki

General Stop Dudziro yeP6:

Sheb: 1 - 10 x 1000 x 2000mm (tsika dzetsika zvakare dzinogona kupihwa)
