Cov tub ntxhais tseem ceeb ntawm kev siv cov nplaum muaj cov nplaum tus neeg sawv cev
1, Tus neeg hla kev ntoo khaub lig yog dab tsi?
Hla cov neeg sawv cev yog cov sib xyaw ua ke muaj ntau pab pawg uas cuam tshuam los ntawm cov khoom siv hluav taws xob ntawm tshav kub, lossis ua kom sov, thiab txo cov huab cua ua kom muaj zog los ntawm ntau dua 90%. Piv txwv li, tom qab roj hmab yog crosslinked nrog cov leej faj, cov molecular chains ua ib cov khoom lag luam elastic, uas tuaj yeem siv los tsim cov khoom lag luam xws li cov log tsheb.
2, kev faib tawm thiab cov neeg sawv cev raug sawv cev ntawm cov neeg sawv cev
1) Ntau ntau lub chaw ua haujlwm:
Carboxylic acids (xws li phthalic anhydride), amines (xws li Ethylenediamine), thiab Sulphur (roj hmab vulcanizing tus neeg sawv cev).
2) Cov ntaub ntawv cog lus tsis txaus ntseeg:
Taiic (txhim kho tshav kub tsis kam mus rau saum toj no 180 degree), cov ntaub ntawv los tiv thaiv tus qauv huab loj loj sib txawv).
3) Dynamic Reversible System:
Dielsalder Hom (ua tiav kev kho tus kheej), disulfide daim ntawv cog lus (txhim kho kev qaug zog tsis kam).
3, Kev Siv Khoom Siv
1) cov qauv nplaum nplaum:
Thaum amine crosslinking cov neeg sawv cev yog siv rau epoxy cob, lub zog shear nce mus txog 18-22mpa; Acid anhydride crosslinking tsa cov kub deformation kub txog 148℃thiab lub ntim resistivity ntau dua li 1 ¹⁵ω ¹⁵ω ¹⁵ω. DMA nthuav tawm ib qho kev cia khoom ntawm 3.2 GPA thiab ntsev txau tiv taus rau ntau dua 1000 teev.
2) Iav nplaum teb:
Thaum Silicone Adhesive yog crosslinked nrog Ethyliced nrog Ethosilicate, nws lub zog tensile nce mus txog 1.8mpa (raws li GB / T14683). Thaum cov ntoo khaub lig sib txuas yog 1.5%, cov nplaum nplaum tuaj yeem tiv thaiv ib qho kev deformation ntawm 30cm, thiab lub chaw nres tsheb Xiong'an tom qab 600000 mus.
4, kev siv cov cim kev xaiv
1) Kev ua kis las: Cov pab pawg ua haujlwm ntawm cov pab pawg ua haujlwm ntawm substrate thiab tus neeg sawv cev hla kev sib txuas;
2) Cov txheej txheem tswj: Tai yuav tsum tau ua kom sov siab ntawm 140 degree;
3) Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: ua raws li cov qauv zoo li GB 33372-2020.
5, Kev Lag Luam Kev Lag Luam Kev Lag Luam
1) Dynamic hla kev sib txuas: dielsalder hom ua tau zoo lub neej ntawm 3.08 lab mus;
2) Nanotechnology: Sio O grafted nrog vinyl txhim kho kev ua tau zoo los ntawm 60%;
3) Cov ntaub ntawv biobased: itaconic anhydride hloov kho roj taum pauv nrog cov ntsiab lus biochar ntawm ntau dua lossis sib npaug rau 40%.
Cov neeg sawv cev hla kev txhawb nqa macroscopic kev cia siab los ntawm microscopic architecture los ntawm kev ua kom muaj kev lag luam ua kom muaj cov khoom siv los ntawm kev ua haujlwm hauv hluav taws xob rau hauv ntim tshuab hluav taws xob.
