Cov ntaub ntawv yooj yim
Hloov kho polyp-benzoyl-p-phenylenediamine (PPA) yas thermal deformation kub txog li 300 degree saum toj no, siv tas li kub txog 170 degree, tuaj yeem ua tau raws li koj cov kev xav tau rau luv luv - thiab kev ua haujlwm ntev thermal. Nws tuav nws cov cuab yeej zoo tshaj plaws - lub zog, hardness, qaug zog tiv thaiv thiab creep tsis kam - dhau ntau qhov kub thiab txias. Toughened Lv PPA ua ke nrog superior toughness thiab ib tug ntau yam ntawm hardness thiab yooj, nyob rau hauv lub fastener yuav tsum tau rau ib leeg-siv rigidity, raws li zoo raws li rov siv flexure zoo xaiv. Cov khoom lag luam tshwj xeeb kuj muaj rau cov tshuaj tsuag thiab electroplated, hluav taws kub, glycol tsis kam thiab daim ntawv thov reflexive.
yam ntxwv
☆ PPA lub zog, toughness thiab hardness superior kev ua tau zoo, nrog rau nws cov cua sov ua haujlwm zoo, tshuaj tiv thaiv thiab tawg tsis kam
☆ PPA tuaj yeem tswj tau lub zog thiab tawv hauv qhov kub thiab txias ib puag ncig, thiab tuaj yeem siv los hloov cov hlau hauv cov tsoos nylon thiab polyester
☆ PPA yas kuj muaj superior gloss. Nws tuaj yeem ua xim es tsis txhob txau, yog li pab txo qis qhov tsos ntawm khawb thiab khawb ntawm qhov chaw.
☆ PPA plastics kuj muaj kev ua haujlwm zoo thiab tso cai rau lub sijhawm luv luv
Piv nrog PA46:
√PPA muaj thermal stability ntau dua PA46.
√PPA tau zoo dua CTI / arc tsis kam thiab infrared co-tam sim no muaj peev xwm tshaj PA46;
√PPA muaj tshuaj tiv thaiv zoo dua PA46;
Daim ntawv thov
☆ Automotive Cheebtsam, suav nrog roj, kis tau tus mob thiab lub cav tshuab, txo qhov hnyav, tus nqi thiab muab kev pab lub neej ntev;
☆ Chipset thiab lub qhov (socket), khob lub cev vuam kev txhawb nqa;
☆ Chip capacitor, hloov thiab me me horn, siab ceev luam tawm Circuit Board connector;
☆ Rau kev coj ua ntawm lub sijhawm siab, xws li tsis muaj lubrication bearing, foob, bearing cais nplhaib thiab reciprocating qhib compressor qhov chaw;
☆ Connectors, controllers, sensors, motors and other key electronic parts
Feem ntau ntawm PPA resins yog ua tiav los ntawm kev txhaj tshuaj molding.
PPA raw cov ntaub ntawv yog pre-dried rau cov av noo ntawm tsawg tshaj li 0.1 feem pua thiab ces ntim rau hauv tshav kub-sealed hlau lub zos hnab los yog thawv. Cov thawv no xyuas kom meej tias PPA cov ntaub ntawv nyoos tsis tas yuav qhuav ua ntej ua.
Cov av noo txaus rau cov txheej txheem yog 0.15 feem pua lossis qis dua. Kev ua haujlwm ntub dej tuaj yeem txo qhov hnyav molecular, ua rau poob ntawm cov khoom siv kho tshuab.
Siv lub tshuab ziab khaub ncaws desiccant, nws yooj yim kom qhuav cov resin mus rau qhov dej ntws ntawm 25 degree F lossis qis dua ntawm 175 degree F. Lub sij hawm ziab yog nyob ntawm qhov nqus dej, feem ntau nyob rau hauv thaj tsam ntawm 4-16 teev.
Txhaj molding melting kub nyob rau hauv qhov ntau ntawm 615-650 degree F, cov khoom nyob rau hauv lub chim ntawm lub sij hawm nyob twj ywm tsis ntau tshaj 10 feeb, yog li ntawd cov khoom tawm ntawm lub txhaj tshuaj molding mechanical kev ua tau zoo yog qhov zoo tshaj plaws.
Lub pwm kub ntawm yam tsawg kawg yog 275 degree F yuav tsum tau ua kom tiav crystallization thiab pom qhov seem stability.
Cov khoom uas muaj cov phab ntsa tuab tuaj yeem raug txhaj rau ntawm qhov kub qis dua vim qhov txias txias.
Qhov kub ntawm qhov tuag yog ib qho tseem ceeb heev los txhim kho qhov kev xav ntawm qhov chaw tiav.
Cov pwm saum npoo kub ntawm cov ntxhia muab tub lim qib PPA resin rau lub tshuab nqus tsev kub plating hlau yuav tsum yog 350 degree F.
