ASTM tus qauv tshiab txhawb kev siv silica hauv cov log tsheb, txhawb kev ruaj ntseg

ASTM tus qauv tshiab yuav raug siv los ntsuas qhov zoo ntawm silica, cov khoom siv raw uas tsim lub hauv paus rau "greener" log tsheb.Cov tuam txhab log tsheb thiab cov neeg tsim khoom siv silica yuav yog thawj cov neeg siv ntawm tus qauv tshiab (D8016, Test Method for Silica, Precipitated, Hydrated - Sears Number).Raws li ASTM tus tswvcuab Jorge Lacayo-Pineda, silica thev naus laus zis txhim kho kev ua haujlwm ntawm lub log-rolling kuj tsis muaj kev cuam tshuam hauv kev ua haujlwm ntawm kev sib tsoo.Qhov no ua rau kom zoo dua roj efficiency, nrog rau txo cov pa roj carbon dioxide emission hauv tsheb.Cov tuam txhab roj hmab, cov neeg siv tseem ceeb ntawm cov silica precipitated, tuaj yeem txhim kho lawv cov kev qhia tshwj xeeb thiab ua kom cov khoom zoo los ntawm kev sim rau tus qauv tshiab, nws hais.ASTM pawg neeg ua haujlwm uas tsim D8016 npaj yuav ua qhov kev sim ntsuas kev sib tw rau lub caij nplooj ntoo hlav tom ntej los ntsuas tus qauv tshiab qhov tseeb.Rubber tuam txhab labs, cov neeg tsim khoom silica thiab cov tsev kawm ntawv raug txhawb kom koom nrog.Cov neeg koom nrog hauv txoj kev tshawb no yuav muab cov qauv los tshuaj xyuas raws li tus qauv tshiab.

Precipitated silica

Bonding, tiv thaiv adhesion, tiv thaiv caking, coagulation, tswj kev tso tawm, cov cab kuj, txaus pab, txhim kho cov nyhuv luam ntawv, txhua yam kev txiav txim, tshwj xeeb additives rau thermoplastic, reinforcement, rheological tswj thiab whitening.Hydrophobic silica kho los ntawm kev hloov kho saum npoo yog yooj yim soluble hauv roj.Thaum nws tau siv los ua cov khoom siv ntxiv rau hauv cov roj hmab thiab cov yas, cov khoom siv dag zog thiab tsim kua muag ntawm nws cov khoom yuav raug txhim kho zoo.

Precipitated silica muaj ntau yam kev siv, thiab cov khoom sib txawv muaj kev siv sib txawv.Raws li tus neeg saib xyuas zoo rau cov khoom siv roj hmab, nws qhov kev ua tau zoo yog qhov thib ob tsuas yog cov pa roj carbon dub, thiab txawm tias zoo dua li cov pa roj carbon dub tom qab ultra-nplua thiab tsim nyog kho qhov chaw.Nws yog tshwj xeeb tshaj yog tsim rau kev tsim khoom dawb, xim thiab lub teeb xim roj hmab khoom.Nws yog siv los ua thickener los yog thickener, blending tus neeg sawv cev ntawm hluavtaws roj thiab insulating xim, dimming tus neeg saib xyuas ntawm cov xim, thixotropic tus neeg saib xyuas ntawm cov khoom siv hluav taws xob ntim khoom, precipitant ntawm phosphor thaum lub sij hawm fluorescent npo txheej, muab tub lim xim luam ntawv roj hmab phaj thiab pwm tso tus neeg sawv cev rau casting. .Ntxiv rau hauv cov resin tuaj yeem txhim kho cov dej-pov thawj thiab rwb thaiv tsev ntawm cov resin.Cov khoom ntim hauv cov khoom yas tuaj yeem ua rau kom muaj kev tiv thaiv thiab roj ua haujlwm.
