PP-raws li Carbon Nanotube Conductive Masterbatch Khoom Taw Qhia
Product Positioning thiab Technical Features
Peb lub tuam txhab PP-raws li Carbon Nanotube (CNT) Conductive Masterbatch yog ib qho kev daws teeb meem tshiab tsim los daws cov teeb meem ntawm kev faib cov khoom siv rau cov khoom siv polypropylene. Los ntawm peb tus tswv cuab "Interfacial Bridging" thev naus laus zis, peb tau kov yeej kev lag luam - thoob plaws lub hwj chim ntawm kev tsis sib haum xeeb thiab kev sib cuam tshuam ntawm CNTs hauv qhov tsis yog -polar PP matrix. Qhov no ua rau muaj kev ruaj ntseg ntawm peb-sib nqus conductive network ntawm kev thauj khoom tsawg heev, paving txoj kev tshiab thev naus laus zis rau loj- nplai, nqi- siv tau, siab- kev ua haujlwm ntawm cov ntaub ntawv yas.
Cov ntsiab cai tseem ceeb
Interfacial Bridging Technology
Siv ib qho tshwj xeeb dual -functionalization txheej txheem ntawm "polymer grafting - nanotube anchoring":
Molecular-Level Interface Design: Grafts polar functional pawg mus rau PP molecular chains los ua qhov chaw ua haujlwm rau kev sib txuas nrog CNTs.
Directed Anchoring Mechanism: Hloov kho CNT nto nrog cov pab pawg reactive ntxiv rau PP pawg ua haujlwm, ua kom muaj kev sib raug zoo tshuaj.
Network Self-Kev sib sau: Thaum lub sij hawm melting, functionalized CNTs spontaneously tsim ib tug percolating network tsav los ntawm thermodynamics.
Crystallization Modulation nyhuv
CNTs ua raws li heterogeneous nucleating cov neeg ua haujlwm, txhim kho PP crystallization tus nqi thiab qib:
-Crystal Induction: Txhawb kev tsim ntawm - crystals hauv PP, txhim kho cov khoom toughness.
Spherulite Loj Tswj: Refines spherulite loj, txhim kho cov khoom clarity.
Dimensional Stability: Txo thermal shrinkage, txhim kho qhov precision.
Quality Control System
Raw Material Control
CNT kuaj: Dual screening using Raman spectroscopy and TEM, ensuring G/D ratio >10, nam ratio 150-300.
PP Matrix Qib: Qib sib txuam raws li MFR, tacticity, molecular hnyav tis.
Functional Additive Optimization: Compounded antioxidants, lub teeb stabilizers, thiab kev pab ua kom muaj kev ruaj ntseg ntev -.
Cov txheej txheem ntau lawm tswj
Ua ntej- txheej txheem dispersion: Solvent-assisted pre-dispersion, achieving primary CNT dispersion >95%.
Melt Compounding Theem: Zone- tswj qhov kub thiab txias hauv ntxaib- ntsia hlau extruder, gradient tswj ± 2℃.
Online Monitoring System:
Kev saib xyuas kev tiv thaiv online: sau cov ntaub ntawv txhua 10 vib nas this.
Kev tswj qhov kub siab hloov pauv: < ± 5%.
Particle loj saib xyuas: D50 tswj ntawm 2.0-2.5 hli.
Cov Khoom Siv Ua tiav Cov Qauv Ntsuas
Conductivity Verification: Txheeb xyuas los ntawm plaub- taw tes sojntsuam thiab txoj kev tiv thaiv saum npoo.
Kev soj ntsuam Dispersion: Cov duab tsom xam qhov system los ntsuam xyuas cov qib dispersion, kom ntseeg tau tus qauv A.
Accelerated Aging Test: 1000 hours at 85°C/85% RH, property retention rate >90%.
Batch Consistency: Statistical Process Control (SPC), Cpk value >1.67.
Application Performance Validation
Kev Xeem Ua Haujlwm: Validating ua qhov rais ntawm ntau hom kev txhaj tshuaj molding tshuab.
Kev Xeem Ua Haujlwm Kawg: Kev tsim cov qauv kuaj cov qauv los kuaj xyuas qhov kawg ntawm cov khoom.
Cov Neeg Siv Kev Sib Tham: Muab cov kev sim sib tw los sau cov ntaub ntawv tiag - ntiaj teb daim ntawv thov.
Xaiv peb PP-raws li Carbon Nanotube Conductive Masterbatch txhais tau hais tias tsis yog tsuas yog cov khoom siv siab tshaj -, tab sis ua tiav cov khoom siv yas. Peb tau cog lus los pab peb cov neeg siv khoom kom ua tiav cov khoom lag luam hloov khoom dua tshiab thiab thev naus laus zis leaps thaum tswj hwm tus nqi zoo.
Rau cov qauv los yog kev sab laj, thov hu rau peb pab neeg txhawb nqa. Peb yuav muab cov kev pabcuam customized.
