Mechancal, magetsi, magetsi uye emakemikari zvivakwa zvePolyamide (PA) anoona

Polyamide (pa) yakakwira molecular compound kubva kuLactam Polyamide anoomeswa ane-pachena kana mukaka chena crystalline yerudzi rwemanyorerwo, . car lead. Kushanda zvakanaka, kurongedza zvakanaka. Iko kushomeka ndeyekuti iyo mvura yekunyora yakakura, inokanganisa kugadzikana kwemukati uye zvivakwa zvemagetsi. Kusimbiswa neFiber kunogona kuderedza iyo mvura yekumira kweiyo resin, kuitira kuti ishande mukupisa kwakanyanya uye yakakwirira mamiriro ekushisa.

1. Zvivakwa zveAnowanzoshandiswa polyamides

PA MAYITIES IS PA6, PA66, PA11, PA12, PA26, PA26, PAA6, PASTHING POLYAMISID YAKABUDA, % yekugadzirwa kwe polyamide. Iyo makemikari chimiro chemapuranga akasiyana siyana akasiyana, uye zvivakwa zvavo zvakare zvakasiyana zvakare. Tafura 1-1 inorondedzera zvivakwa zvevamwe zvinowanzo shandiswa polyamendes.

2.Mechanical Properties

Polyamide molecular cheni ine polar mapoka emapoka, anogona kuumba intermolecular hydrogen, crystallinity, saka ine simba rakasimba uye rodulus. Nekuwedzera kweiyo eide group density, molecular cheni yemicheka uye kuchema, simba rayo rinowedzera; Nekuwedzera kweboka reMethyl muPolyamide Carnecular, Simba reMuchina rinoderera, nepo simba rekukanganisa rinowedzera zvishoma nezvishoma. Nhungamiro yeAryl mapoka muPolyamide molecular keteni zvakare inowedzerawo simba nekuda kwekuwedzera kwesimba uye kuwedzera masimba (semuenzaniso vanakaya mauto) pakati pemaketani anonyomba. Pakati pedzimba, pa66 ane hutsinye hwepamusoro-soro uye kuomarara, asi kuomarara kwakaderera. Mhando dzese dzePolyamide zvichienderana neyakaomeswa saizi: Pa66 <pa11 <pa12 <pa1010 <pa6 <pa61 Polyamide crystallinity, ine simba rakakura pazvinhu zvekushandisa, simba reSimba rinoshanduka, Simba rinoshanduka, rombo rakanaka mukuwedzera kwekuchema uye nekuvandudza. Boka racho raiye marefu mune keteni huru yePolyamide molecule boka, iro rinoita kuti polyamide ine mvura yekunyora mvura. Kubata kwemvura kune simba rakakura pazvinhu zvePolyamide, mushure mekutora mvura, simba rekutadza nekukotama uye nekukanganiswa zvakanyanya, kukura kwechigadzirwa kunoshanduka zvakanyanya, asi simba rekukanganisa rikwanda kwazvo, Ona Tafura 2-1.

3. Zvivakwa zvemagetsi

Polyamide ine yakanaka yemagetsi masisitimu ekusimbisa, tafura 3-1 inorondedzera mamwe emagetsi zvivakwa zvePolyamide. Kunyangwe hazvo polyamide ine yakanaka yemagetsi zvemagetsi, ine polar mapoka mapoka mune keteni huru yemamorekuru uye imvura-inonakidza yemvura polymer. Sezvo mwero wekutora mvura uchiwedzera, kusimba kwehuwandu uye dielectric simba rePolyamide anoderera, kugadzira polyamide mapuranga asina kujairika kuti ashandiswe magetsi emagetsi emagetsi emagetsi uye neyakagara yakawanda uye yakasimba nzvimbo.

4. Inopisa Zvivakwa

Nzvimbo yekunyungudutsa yemarudzi akasiyana ePolyamide inosiyana kwazvo, iyo yakakwira inonyungudika polling iri pa46, kusvika 295 ℃. Polyamide ine huwandu hwakasiyana hwekushandisa tembiricha, kazhinji kubva -40 kusvika 100 ° C. Iyo yekupisa inokanganisa tembiricha yePolyamide inosimbisa zvakanyanya pane mutoro. Iyo yekupisa inokanganisa tembiricha yemapuranga inoenderana zvakanyanya nemutoro wavanoiswa pasi, uye kuderera nekukurumidza nekuwedzera mutoro. Maitiro ekufungidzira emapuranga akasiyana siyana haasiye zvakanyanya, sezvakaratidzwa muTafura 1-1. Kupisa kwekurovera kweiyo akasiyana mapuranga anoratidzwa muTafura 4-1. Kupisa kwechiitiko cheP6 uye pa66 kwakafanana, nepo iyo pa610 yakakwira uye iyo yePa11 ndiyo yepamusoro.

5. makemikari zvivakwa

Polyamide akasungirirwa kune mamwe makemikari reagents, kunyanya peturu, mafuta uye mamwe mafuta ekuramba, pa11 kurwisa mafuta akanaka, ndiyo yekutanga sarudzo yezvinhu zvemumotokari mitsara. Nekudaro, zvinonyangadza muPhenol, Inorward Inorganic acid uye yakagadzirirwa acid pamhepo tembiriti, methanol Solidcol, Calculene Glycol. Muzhinji, mapuranga mazhinji emapuranga akagadzikana mumhinduro dzeAlkaline, asi hydrolysis kana kusvibiswa kunoitika pakudziya kwakanyanya, kunyanya polyamide ichanyauswa; Pasi pemamiriro ezvinhu aya, Amines Acids uye maAcds, kunyanya kuora kwecids, anokwanisa kushora acids, achikonzera kuparara kwemusungo, uye pakupedzisira kuunza Monomer yePolyamide. Polyamids inotsamwisa kupisa kupisa pakupisa kwakanyanya. Pamusoro pekushatisa kwekunyora, kusvibiswa kwe oxidative kunoitika kana polyamide ichipiswa mumhepo. Semuenzaniso, pa66 inova brittle mushure mekurapwa pa250 ° C ye 2h kana 70 ° C kwemakore maviri. Mukudzidzira, kazhinji mukugadziriswa kwezvigadzirwa zvePolyamide, wedzera mamwe antioxidants kuti inhibit thermal oxidative degration. Polyamide muchiedza, nekuda kwekuenda kuIltraviolet radiation, zvichaitikawo PhotoDogradation kana kuchembera. Polyamide ine carbononyl boka, inogona kutora ultraviolet mwenje muchiedza cheketani uye kuyambuka, mukushaikwa kweiyo oxyGen mwenje, PA6 uye PA6 uye PA6 DECOMPOTION MU H2, CO uye HYDROCABONS. UV inobata uye yakatadzisa ambine mwenje maStabilizers inogona kuwedzerwa kuti uwedzere kugadzikana kwechiedza chePolyamitides.
