Lwm nta PI (Polyimide)

SOLVER POLYIMIDE | Updated: Sep 15, 2014

Tus ceev txog PI 1.28-1.48g/cm3, nrog rau lub imidization kawm ntawv ua no, yuav kom ceev; Thaum twg uas muaj tej neeg nyob hauv cov saw hlau loj, ceev yuav tau me me thiab. PI lawm ntau dua compression tensile, dabtsi yog khoov, lub zog, txhua yam khoom rau nruab nrab thiab lub seb tug, tus modulus siab, tshwj xeeb tshaj yog thaum muaj modulus siab yog ib feature mas ntawm nws txhua yam khoom.

Txav resistant nplaum PI lawm yav tom ntej seem stability, yog kawg mas.

Feem ntau mas ntawv uas PI yog nws kub heev kuj yog kub, qhov kub decomposition ntawm cov iav qhov hloov kub, thermal kev kawm muaj siab tshaj, thiab tus nruam kub. Nruam kub ua hauj lwm yog 250 ℃.

PI Ted hluav taws xob rwb thaiv tsev zog, hauv ntau hom kub dipole tsis yog tsawg. Nws muaj cov corona kuj zoo tshaj plaws, los yog vim muaj ob hom tshuaj tiv thaiv kom neeg Corona tshuaj: oxidation yam pa atoms decomposition; oxidation Event ntawm nws, hydroxides yog resistant heev. PI belongs rau cov khoom siv dielectric intermediate.

PI muaj zoo stability rau roj, organic kuab tshuaj, nta kua qaub, tiam sis tsis tiv taus zog oxidation concentrated sulfuric acid thiab fuming nitric acid, kuj ntaus tsis alkali resistant thiab chav superheated. Oxidative degradation tshwm sim ntawm kev muaj zog oxidants. Alkali thiab dej vapor nyhuv yuav ua rau PI imide ntiv nplhaib qhib thiab qaum puas tshwm sim li, cov kev kawm degradation resulting.

Vim muaj coob tus uas muaj ntxhiab molecular saw rau PI nplhaib qauv uas absorbs tawg muaj peev xwm no muaj zog heev, yog li ntawd lawm kuj tawg yav tom ntej, nws yuav sawv hauv neutron, electron, 7 rays, ultraviolet tawg, tawg nyob, txoj kev dlha degradation no tsuas siv heev.


  • 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....
