Nylon vs. Pom

Kusiyanisa pakati pePom zvinhu uye nylon kuri seinotevera:

Kugadzirisa Kugadziriswa Kwemhando: POM iri nani pane nylon

Mumamiriro ezvinhu akanyorovesa: Nylon inobata mvura uye defoms muhukuru.

Panyaya yeSimba rezvinhu: Nylon yakasimba

Density: nylon ndeye 1.14, pom ndeye 1.4.

Mukudziya kwakanyanya: Nylon yakanaka, inosvika kuma120 degrees

Coefficient yefinji: pom idiki

Panyaya yekukanganisa simba: Pom yakanaka

Panyaya yeAbraasion Rishance: Pom yakanaka

Muchidimbu, nylon mvura yekunyora, kupfeka-kuramba zvakajairwa, simba rakanaka, kupisa kwakanaka.

Kuomesereka pom kwakanaka, pfeka kurwisa kwakanaka, kudzikisira kwakasimba, kurova kwakanaka;

Chii chinonzi pom?

Pom (PolyoxyMexyMele resin) Tsanangudzo: Polyoxymymylylylyle is a Lord Carget Sekureva kwemakemikari akasiyana emakemikari mune yayo molecular cheni, inogona kukamurwa kuita homo- uye copelmererization ye formaldehyde. Kusiyanisa pakati pezviviri zviri: Homopolymerization of formaldehyde density, crytallytinity, asi yakanaka yekudzikisira, yakakwana yekugadzirisa tembiricha (anenge 50 ℃), kugadzikana kweAcid naAlkali. Iyo ipurasitiki yeinjiniya ine hunyanzvi hwakanakisa hwakakwana. Iva nemabasa akanaka emuviri, muchimiro uye makemikari, kunyanya kupokana kwakanaka.

Inowanzo zivikanwa sejaho resel kana kubata simbi, yechitatu yakakura general engineering mapurasitiki. Inokodzera kugadzirwa kwekupfeka zvikamu, kutamisa zvikamu, uye indasitiri yemakemikari, chishandiso uye zvimwe zvikamu.

Rudzii rwezvinyorwa "nderudzi rwe" Nyoni "?

Nylon (Nylon) inozivikanwa nemakemikari sePolyamide (PA), izwi rePolyurethane Fiber, IE NYLON, YEMAHARA YEMAHARA YEMAHARA. Iro izwi rakawanda rekuti Thermoplastic resins ayo ane kudzokorora mapoka emides mumakero makuru emamorekuru. Nekudaro kune akawanda marudzi eNYlon asiri kureva chinhu chimwe chete. Izvi zvinosanganisirawo aliphatic pa, aliphatic-anomatic PA, uye anonhuhwirira pa. Pane awa, Aliphatic pa yakasiyana-siyana, yakanyanya kugadzirwa, uye yakashandiswa zvakanyanya zvekuti danho rayo rinotsanangurwa neiyo nhamba yekaroni maatomu emukati mune synthetic menomer.

Yetatu, Nylon hunhu

1. ine zvinhu zvakanakisa zvemakaniki, simba rakanyanya simba, kutambudzika kwakanaka. Nylon seyakagadzirwa fiber, yakanyanya kunaka mukana wekupfeka zvakakwirira kupfuura mamwe machira ekurwisa, kagumi. Abrasion anodzivisa; Kana yakatambanudzwa kusvika ku3-6%, iyo elasticity yemuyero wekupora kusvika ku100%; kugona kutsungirira makumi ezviuru zvenguva yekupeta uye kusaputsa.

2. Kuzvinyudza kwakanaka, kupokana kwakanaka, nylon kune yakanaka kwazvo yekuzvinyomba, iyo yekukakavara ndeyekuti idiki.

3. Ine yakanakisa kupisa kupesana, kupokana kwemamiriro ekunze.

4. Mhando dzakanakisa dzekusimbisa kwesimbe

5. Nekunyora kwemvura, nylon yemvura kubviswa, zviri nyore kutungamira kuchinja muhukuru hwechigadzirwa uye kuita. Nekudaro, kuguma kweketani huru yemamorekuru vePolyamide ine terminal amino uye carboxyl mapoka, pasi pemamwe mamiriro ane rimwe basa rekuita. Naizvozvo, kubudikidza nekuvharidzira, kusanganisa, kusimbisa uye kusimbisa nzira dzakadai sekushandurwa kwemakemikari nekuchinjika kwemuviri kukurira mvura yakakura uye shanduko yekuita.

Chechina, iyo application yeNYLON

Kune maviri mainini maincation of nylon, kuberekwa kwekutanga kunoshandiswa seyakagadzirwa mameseji. Izvi zvinogona kuoneka kubva kuIzwi nylon mune dzakawanda dzezvipfeko zvedu zvipfeko. MuHondo Yenyika II nekuda kweNylon inowanzoshandiswa paratroopers parachutes, yunifomu yemauto uye zvimwe zvinodikanwa zvehondo, izvo zvakafarirwa nezvinhu zvevakadzi zvevakadzi kuti zvive zvekutora, saka mutengo wazvo wakamuka zvakanyanya Kuti pasi pevarombo varombo vaifanira kushandisa chinyoreso kuti tiratidze seams mumakumbo avo zvakafanana neylon masokisi muchimiro, uye kusekerera se "mashiripiti ezvemashiripiti!"

Kune rimwe divi, nylon haisi chete isina chepfu uye kuremerwa, asi zvakare ine simba rakanyanya kunaka, rakanaka kwazvo basa rekurwisa uye rakanaka kurwisa. Saka nylon yakashandiswa kugadzira mapurasitiki ekutsiva simbi, iron, mhangura uye zvimwe zvinhu kutanga kwema1950s. Naizvozvo, nyoni yeNylon English inowanzo shandiswa mukugadzirwa kwemapurasitiki ekupfeka, kuumbwa kwemidziyo, nhengo dzeimba, dzimba dzekudzivirira kuti dzizvipengenhu, michina yemakemikari, michina yemakemikari. Akaita sehombodo, maGears, fani, nevarume, makaruki, transs, mashanga, zvidimbu, zvisimbiso ,, shutings, shuwa, shuwa dzinobatanidza uye zvichingodaro.

Inylon kana pom iri nani yekugadzira mapurasitiki maGears?

Pom naNylon zvinhu zviviri zvakajairika zvemagiya epurasitiki, uye shamwari zhinji dzinogara dzisina chokwadi kana uchisarudza zvinhu zvepurasitiki. Tinofanira kushandisa nylon sechinhu ichocho? Kana pom? Ndeipi sarudzo yakakodzera kuti uwane iyo yakanyanya mutengo-inoshanda?

Nylon uye pom makuru emakwikwi

Nylon ine zvakanakisa zviitiko zvakazara, kunyanya zvinokanganisa kupokana, kupokana neabrasion kupokana, kuramba uye kupisa kurwisa, kwakawanda kutaura nezvazvo.

1) Yakanakisa mechanical basa. Nylon ine simba rakareba rekuita uye kuramba kwakanaka.

2) Kuzvishingisa kwakanaka uye kupokana nekukonana. Nylon ine yakanaka yekuzvifunga, yakaderera coefficidents yekukakavara, uye hupenyu hwakareba sehupenyu hwekuendesa.

3) Yakanakisa kupisa kupesana. Akadai saNylon 46 uye mamwe akakwirira crystalline nylon, yakakwira kupisa kukanganisa tembiricha, inogona kushandiswa kwenguva yakareba muna 150 ℃. Nylon yakasimbiswa negirazi fiber, kupisa kwayo kupisa kupisa kunosvikira anopfuura 250 ℃.

4) Yakanakisa yemagetsi insulation basa. Nepamusoro pakawanda kupesana uye kuputsa voltage, nylon ndiyo yakaisvonaka yemagetsi uye yemagetsi zvinhu zvekusimbisa zvinhu.

5) kuramba kwakasimba kwemamiriro ekunze.

6) mvura yekunyudza. Nylon ine mwero wepamusoro-soro ekutora, akaguta nemvura kusvika ku3% kana anopfuura, ayo anokanganisa kudzikisira kwezvikamu kusvika pamwero wakati.

Pom, polyoxymethylene, anozivikanwawo se "dzinza", "Race Pamusoro PAMambo Kong!"

(1) Simba rakakwirira rekuita uye kuomarara;

(2) Simba rakanyanya kupera simba;

(3) kuramba kwakasimba, kuramba kwakanaka kune organic sol;

(4) kuramba kukuru kudzokorora kudzokorora;

(5) zvimiro zvemagetsi zvakatemerwa;

(6) kupora kwakanaka;

(7) Kuzvisarudzira kwekuzvinyudza uye kushoma kupokana;

(8) Kugadzikana kwakasimba kwakasimba;

(9) zvakafanana nekutanga kushandira tembiricha, chete 70 ~ 80 ℃;

(10) Hapana murazvo unodzora giredhi; kwete kuramba ku hydrolysis.

3, kukanganisa kurwisa, uye kubata kwemvura: Kana chigadzirwa chako chichiwanzotengwa kazhinji, chinoda kukanganisa kupokana, nekuvhara kwemvura, senge pom haina hydrolysisant, kunyangwe Kupesana kwayo kunobata kwakanaka kwazvo.

4, kuomarara uye kurwisa Abrasion: Kana zvaunoda zvakanakira kuomesa, mutengo wakaderera, hapana zvinodiwa pakudziya, sarudza pom.

5, kuramba uye kuomarara: kuti kupokana uye kuomarara zvinodiwa ruzivo, nylon kwakakodzera.

6, mutoro: wepakati uye akaderera mutoro, tora pom.

Kushandiswa

Nylon: Nylon inogona kushandiswa mukufamba kwese kwehupenyu, asi mumabasa anotevera anoshandiswa z more: zvikamu zvemotokari (nekuda kwekuwedzera kwehurongwa, kupokana nekupokana, kupokana kwakanaka); fenicha yehofisi; Zvimedu zvikamu (yakanaka corrosion kuramba); magetsi uye zvemagetsi zvishandiso (zvakanakisa zvemagetsi basa).

POM: POM inoshandiswa mumidziyo yemagetsi uye yemagetsi, mechancal mitezo, kunyanya muzvikamu zvemapurasitiki, kunyanya mumagiya epurasitiki, mapuranga, fani, zvikamu zvemota zvinoshandiswa zvakanyanya.
