Carbon Fiber Reinforced PE Pipe (CF-PE Pipe) yog lub siab-cov kav dej sib xyaw ua ke, ua los ntawm cov khoom siv hauv HDPE thiab carbon fiber reinforcement. Nws nta kev kub siab ua haujlwm, lub nplhaib siab nruj thiab tiv thaiv - corrosion, dav siv hauv dej, tshuaj lom neeg thiab kev thauj mus los tsuas.
1. Raw Material Selection Standard
Cov khoom tsim nyog raw khoom yog qhov chaw ntawm cov yeeb nkab ruaj khov. Cov mis sib npaug yog qhia hauv cov lus hauv qab no:
|
Yam khoom |
Pom zoo Specification |
Ntsiab Lus |
|---|---|---|
|
Base Resin |
PE 80 / PE 100 HDPE |
Xyuas kom zoo yaj fluidity thiab ntev - lub sij hawm kev laus tsis kam |
|
Cov pa roj carbon fiber |
5-9 hli luv-txiav hloov carbon fiber, 20%-50% cov ntsiab lus |
Kev kho deg ua kom muaj kev sib raug zoo nrog PE resin
|
|
Pab txhawb |
Antioxidant, UV stabilizer, roj nplua nyeem |
Tsis txhob degradation ntawm cov khoom thiab txhim kho extrusion smoothness |
2. Cov txheej txheem tsim khoom txheem
Kev lag luam loj ntau lawm ntawm CF-PE yeeb nkab txais kev paub tab co-extrusion txheej txheem, nrog cov kauj ruam yooj yim thiab qauv:
Kauj Ruam 1: Sib tov sib xyawSib tov HDPE hais, carbon fiber thiab additives tusyees los ntawm siab - sib tov ceev kom tsis txhob muaj fiber ntau agglomeration.
Kauj Ruam 2: Composite Pelletizing (Yeem)Twin-Screw extruder compounds raw khoom rau hauv cov khoom sib xyaw pellets kom ruaj khov extrusion.
Kauj ruam 3: Multi- txheej Co-extrusionTxais yuav JBD cov kws tshaj lij tuag kom paub peb - txheej txheej: txheej tiv thaiv HDPE txheej, nruab nrab carbon fiber reinforced txheej, sab hauv du HDPE txheej.
Kauj Ruam 4: Calibration & TxiasLub tshuab nqus tsev calibration tank kho cov yeeb nkab txoj kab uas hla, thiab gradient dej txias tshem tawm kev ntxhov siab thiab deformation.
Kauj ruam 5: Haul-tawm & TxiavMatch extrusion ceev ruaj khov, thiab txiav cov kav dej rau hauv cov kev qhia tshwj xeeb.
Kauj Ruam 6: Kev tshuaj xyuas & ntimNtsuas cov yeeb nkab txhav, siab tsis kam thiab zoo li, ntim cov khoom tsim nyog.
3. Cov txheej txheem tseem ceeb Extrusion Parameters
Kev ruaj ntseg parameter tswj txiav txim siab cov yeeb nkab ua tiav:
|
Tshooj txheej txheem |
Parameter Range |
Muaj nuj nqi |
|---|---|---|
|
Barrel Kub |
180-210 degrees |
Tag nrho melting, tiv thaiv carbon fiber burnout |
|
Tuag Lub taub hau kub |
190-215 degrees |
Smooth yeeb nkab nto, tsis muaj streaks |
|
Vacuum Degree |
-0.06 ~ -0.08MPa |
Tswj cov yeeb nkab txoj kab uas hla ntawm qhov kam rau ua |
|
Ntsia Hlau Ceev |
20-60 rpm |
Tsis txhob over shear puas tsuaj rau carbon fiber |
|
Haul-tawm nrawm |
0.5-2.0m / min |
Match yeeb nkab txoj kab uas hla thiab phab ntsa thickness |
