Siv cov pa roj carbon dub los txhim kho qhov adhesion ntawm cov roj hmab rov siv dua thiab cov khoom siv ua haujlwm
Silicacov khoom yog qhov zoo, nrog rau thaj chaw loj tshwj xeeb, thiab cov nyhuv txhawb zog hauv cov roj hmab yog qhov tseem ceeb. Nws feem ntau yog siv los hloov cov pa roj carbon dub ua tus neeg sawv cev txhawb nqa hauv cov khoom siv roj hmab uas muaj xim zoo nkauj. Hauv kev tsim khoom tiag tiag, cov pa roj carbon dub tsis tuaj yeem tsuas yog siv los ua tus neeg sawv cev txhawb zog, tab sis kuj ua rau kom muaj kev sib txuas ntawm cov khoom siv roj hmab thiab cov pob txha. Piv txwv li, kev sib xyaw ua ke ntawm cov pa roj carbon dub thiab cobalt ntsev tuaj yeem txhim kho qhov adhesion ntawm cov roj hmab rov siv dua thiab cov hlau hlau. Yog li vim li cas silica tuaj yeem txhim kho qhov adhesion ntawm cov roj hmab rov siv dua thiab cov ntaub ntawv ua haujlwm? Cov teeb meem dab tsi yuav tsum tau them sai sai rau thaum sivdawb carbon dubnce adhesion?
1. Yog vim li cas rau silica los txhim kho qhov adhesion ntawm cov roj hmab rov qab thiab cov khoom siv ua haujlwm
Daim ntawv cog lus hydrogen hauv cov pa roj carbon dub yog ib qho yooj yim nqus dej hauv huab cua, thiab hydrogen daim ntawv cog lus tuaj yeem koom nrog pawg hydroxyl los txhim kho kev sib koom ua ke ntawm cov khoom; Silica thiab dej dawb hauv cov roj hmab rov qab tuaj yeem ua rau hauv cov dej tshuaj, yog li ua kom cov adhesion ntawm cov roj hmab rov qab thiab cov khoom siv pob txha los ntawm kev tiv thaiv kev puas tsuaj ntawm cov dej rau cov qauv kev sib txuas; Cov pawg polar nyob rau saum npoo ntawm cov xim dawb carbon dub yuav adsorb vulcanizate hauv cov mis thaum lub sijhawm ua haujlwm, ncua sijhawm vulcanization, muab sijhawm ntau rau kev sib txuas lus. Lub fluidity thiab permeability ntawm cov roj hmab reclaimed yog zoo dua, thiab cov adhesion yog zoo dua.
2. Txhim kho qhov adhesion ntawm cov roj hmab recycled thiab cov khoom siv ua haujlwm. Tus nqi ntawm cov pa roj carbon dub yuav tsum tsis txhob siab dhau
Thaum silica (silicone dioxide) txhim kho qhov adhesion ntawm cov roj hmab rov qab thiab cov khoom siv pob txha, nws cov hydrophilicity yuav ua rau nws nyuaj rau sib npaug sib npaug hauv cov roj hmab sib xyaw. Yog hais tias tus nqi ntawm silica siab dhau lawm, gel yuav raug tsim. Thaum cov roj hmab sib xyaw ua kom tawv thiab cov roj hmab rov qab sib xyaw, nws yuav tsim kom muaj cua sov loj, uas yuav ua rau nws nyuaj rau kev tsim cov khoom qub. Hauv kev tsim khoom tiag tiag, tus nqi ntawm cov pa roj carbon dub yuav tsum raug tswj kom tsis txhob muaj gel.
3. Txhim kho qhov adhesion ntawm cov roj hmab rov ua dua thiab cov khoom siv ua haujlwm. Ua tib zoo saib lub sijhawm ntxiv cov pa roj carbon dub (SiO2)
Txhawm rau txhim kho qhov sib txawv ntawm cov pa roj carbon dub nyob rau hauv cov roj hmab rov qab thiab zam lub cim ntawm cov gel, cov khoom lag luam roj hmab yuav tsum ua kom lub zog shear kom zoo thaum lub sij hawm pib sib tov, thiab ntxiv me me ntawm cov pa roj carbon dub 2YLYY36 hauv cov khoom kom txhim kho. qhov dispersity ntawm dawb carbon dub 2YLYY36 nyob rau hauv lub reclaimed roj hmab thiab txo tshav kub tiam; Ua kom qhov sib xyaw kom zoo thaum sib tov, haus cov dej adsorbed rau ntawm qhov chaw ntawm cov pa roj carbon monoxide dawb rau qee qhov, txo cov cohesion ntawm cov khoom, txhawb kev sib cais ntawm cov pa roj carbon dub hauv cov roj hmab sib xyaw, thiab zam kev tsim cov gel.
Thaum cov pa roj carbon dub yog siv los ua kom cov adhesion ntawm cov roj hmab rov qab thiab cov khoom siv pob txha, cov khoom siv roj hmab tseem yuav tsum xav txog lub luag haujlwm ntawm cov pa roj carbon dub thiab lwm yam khoom ntxiv nrog rau cov khoom siv ntawm cov khoom siv pob txha, tsim nyog kho cov qauv. , thiab ntxiv txhim kho qhov adhesion ntawm cov roj hmab siv dua tshiab thiab cov khoom siv pob txha.
