Kev Polyimide

SOLVER POLYIMIDE | Updated: Sep 15, 2014

Polyimide yog ib tug ntawm cov khoom zoo tej khoom organic polymer, kub 400 ℃, ntev siv kub ntau yam - 200 los 300 DEG C, tsis muaj cuab kev melting point, rwb thaiv tsev siab kuj, tsis tu ncua dielectric txog Hz 4 103, dielectric tsis yog tsuas 0.004 ~ 0.007, F rau H qib rwb thaiv tsev ntaub.

PI hais txog cov caj qaum loj uas ua imino polymer, uas belongs rau lub tebchaw uas muaj ntxhiab, tsis muaj cov yuan ob thiab ob yuan amine anhydride npaj los ntawm polymerization hws. Molecular saw hlau uas PI muaj coob leej faj benzene, thiab pawg imide tau incorporated benzene ntiv nplhaib thiab qhov uas muaj tsib heterocyclic rings membered, tus rigidity ntawm molecular saw hlau, intermolecular forces muaj zog, packing ceev yog muaj, tus PI lawm hauv zog yav tom ntej. PI vim cov qauv hom ob anhydride thiab ob lub amine no tsis zoo li qub, kev kawm zoo rau menyuam haus dog dig sib txawv.

Polyimide yog ib yam khoom tshwj xeeb yam xws li tshuab, tau lug siv aviation, aerospace, microelectronics, nanotechnology, siv lead ua kua, sib cais membrane, laser liaj teb. Tsis ntev los no, txhua lub teb chaws nyob hauv qhov kev tshawb fawb, kev loj hlob thiab siv cov polyimide nyob rau hauv tiam nees-nkaum ib tus tuaj Engineering uas pheej tshaj. Polyimide, vim yog cov koj cov yam ntxwv ntawm tus kheej thiab synthesis, ob leeg ua ib yam khoom los yog li muaj tej khoom tawg yooj yim, nws cov daim ntawv loj loj prospect muaj tau siab to taub, paub tias yuav ua rau tus "teeb meem solver", thiab hais tias "tsis muaj polyimide yuav tsis muaj hnub no lub tshuab Microelectronic".

Polyimide yog polymer uas muaj ntxhiab heterocyclic molecular qauv ntawm lub tebchaw muaj imide pawg saw, Hmong Polyimide (PI), yuav tau muab faib ua benzene PI, soluble PI, polyamide imide (PAI) thiab polyether imide (PEI) 4.

PI yog ib yam zoo tshaj plaws ntawm tshav kub-resistant yam xws li tshuab uas thaum kub, tej yam uas tej zaum yuav ntev mas cov kub ntawm 290 ℃ pliag muaj 490 ℃, rau txhua yam khoom, nkees ua hauj, nplaim retardant khoom hluav taws xob, stability seem, shrinkage zoo, molding me, roj kuj, kua qaub thiab organic kuab tshuaj, tsis ua hauj alkali, yav tom ntej kuj mus txhuam, coj kev kawm.

Thermoplastic polyimide cob (Polyimide cob), hu ua PI) yog ib yam xws li tshuab uas thermoplastic. Nws tseem kub kub thiab txias resistant thermoplastic uas, nrog rau txoj kev hloov mus iav kub kub (243 DEG C) thiab melting point (334 ℃), kub deformation kub txog ℃ 260 (30% iav fiber ntau lossis muaj carbon fiber siv tam qib), yuav siv tau rau ib lub sij hawm ntev ntawm 250 ℃, thiab lwm yam kev kub kub resistant yas as compared with xauj, PPS PTFE, PPO, tej yam xws li, kev siv lub tsuas pub rau qhov kub tshaj 50 ze li ntawm ℃;

PI cob xwb tsis kub kuj tshaj lwm kub kub resistant yas zoo heev, thiab muaj qhov zoo siab muaj zog, siab modulus, siab puas toughness thiab yav tom ntej seem stability; Cob PI yuav tswj siab ntawm kev kub muaj peevxwm ua tau, qhov bending zog ntawm 200 ℃ nce mus txog 24MPa, ntawm 250 dabtsi yog khoov ℃ lub zog thiab lub zog compression tseem yog 12 ~ 13MPa; PI cob rigidity, stability zoo me me, coefficient uas tsis muaj kev tawm expansion, ze heev cov hlau txhuas khoom;

Zoo tshuaj kuj, lub tshuaj nyob hauv hais, tsuas cov concentrated sulfuric acid yaj los txov nws, nws ua hauj corrosion thiab npib tsib xee steel muaj ntsis zoo ib yam, thiab cov nplaim retardant, nplaim mob rau qhov uas qhia tawm cov pa luam yeeb thiab lom gases, anti tawg taus; PI cob tau zoo toughness, cov alternating kev nyuaj siab thiab qaug zog yav tom ntej kuj yog tus tshaj koj cov yas, alloy khoom nrog xauj;

Cov khoom tribological uas PI cob rau koj kuj zawv zawg coj hab fretting coj, kawm yav tom ntej, tshwj xeeb tshaj yog yuav muaj kev kub hnav kuj tsis tshua muaj kev sib txhuam coefficient rau 250 ℃; PI cob yooj yim extrusion thiab molding, yav tom ntej machining kev ua tau zoo, siab molding efficiency txhaj.

Tsis tas li, PI muaj qhov lubrication, yooj yim ua, rwb thaiv tsev stability, hauj hydrolysis thiab lwm yav tom ntej kev kawm ntawv, uas nyob nrog siv rau kev kho mob aerospace, automotive, hluav taws xob thiab hauv, thiab zaub ua thiab lwm teb, txhim kho thiab siv prospects.


  • Tuam txhab profile
    SOLVER POLYIMIDE founded rau lub kaum ib hlis 2010, yog ib lub chaw tsim tshuaj kev thiab qib high tech paus POLYIMIDE (PI) thiab cov khoom uas muaj lub npe "GOLDEN yas". SOLVER POLYIMIDE yog ib lub manufactures ntawm Thermoplastic Polyimide, Thermosetting Polyimide, hmoov Polyimide, Polyimide Pallet, Polyimide ua kua, Polyimide Profile, Polyimide Particle, Polyimide Monomer, Polyimide ua npuas ncauj , Cob polyimide, txheej Polyimide, Polyimide puas khoom, Polyimide siv lead ua kua tuab si lug no thiab hais txog. thermoplastic polyimide hoobkas, tuam txhab, theem muag tag nrho, muas, cov khoom. SOLVER POLYIMIDE polyimide yog ib yam kev kawm siab yam xws li tshuab yas. Nws tsis zoo xwb muaj thermal yav tom ntej, txhua yam, dielectric, stability seem, ua hauj corrosion thiab tawg los tiv thaiv kev, tab sis kuj muaj zoo machinability. Nws yuav tau zoo li tus los ntawm kev sib txawv xws li zoo li molding, extrusion, molding txhaj tshuaj thiab txhaj tshuaj....
