Lub luag haujlwm ntawm silica hmoov

Dawb khiav - kev txhim kho flowability thiab tiv thaiv agglomeration automation txheej txheem yog nce nyob rau hauv cov hmoov ntau lawm thiab siv, txawm li cas los, automation txheej txheem yuav tsum tau hmoov kom muaj zoo flowability los xyuas kom meej kev ntsuas. Tsis tas li ntawd, nws yog ib qho tsim nyog kom tsis txhob muaj cov hmoov agglomeration thaum lub sij hawm cia, vim tias ntau cov khoom hmoov ntawm lub khw muaj teeb meem agglomeration. Qhov no tuaj yeem ua rau kev ntsuas qis qis thaum lub sijhawm tsim khoom.

Cov khoom siv Silicon dioxide tuaj yeem daws cov teeb meem saum toj no thiab pab cov neeg siv khoom txhim kho kev tsim khoom. Lub flowability ntawm hmoov yog feem ntau cuam tshuam los ntawm van der Waals rog thiab lub ntiajteb txawj nqus. Piv nrog rau cov nyhuv ntawm lub ntiajteb txawj nqus, van der Waals quab yuam muaj kev cuam tshuam ntau dua rau cov hmoov zoo. Yog li ntawd, lub finer hmoov, lub poorer nws fluidity.

Tsis tas li ntawd, cov dej ntws tsis zoo kuj tseem tuaj yeem tshwm sim los ntawm cov hauv qab no: cov kua dej ntawm cov hmoov av, xws li dej lossis roj (hauv hygroscopic lossis oily hmoov), cov khoom tsis sib xws uas ua rau ib leeg los ntawm qhov nro, tuaj yeem sib txuas. nrog rau ib leeg thaum lub sij hawm kev thauj mus los thiab kev thauj mus los, thiab hluav taws xob zoo li qub ntawm cov phab ntsa ntawm cov kav dej lossis cov thawv ntim khoom yuav ua rau cov hmoov sib xyaw ua ke. Cov txheej txheem nag lossis daus silica yog ib qho me me, Nws tuaj yeem muab qhwv rau saum npoo ntawm cov ntaub ntawv raw, ua kom qhov sib txawv ntawm cov hmoov hmoov, yog li txo cov nyhuv van der Waals.

Tsis tas li ntawd, silica tseem tuaj yeem nqus dej ntawm cov hmoov av, tiv thaiv dej los ntawm kev sib txuas ntawm cov hmoov. Rau cov hmoov hygroscopic siab, hydrophobic silica yog cov tshuaj zoo dua. Vim lawv qhov tshwj xeeb hydrophobicity, cov silica hais tuaj yeem npog cov yeeb yaj kiab ua kua ntawm cov hmoov av, tiv thaiv kev sib tsoo dej. Raws li cov neeg nqa khoom ua kua, nrog rau kev txhim kho txuas ntxiv ntawm cov txheej txheem kev tsim khoom automation, kev siv cov khoom siv hmoov zoo thiab raug yog nrov zuj zus. Thiab qhov tsim nyog tshaj plaws yog cov dej ntws dawb, tsis muaj agglomerating, thiab tsis muaj plua plavmicro pearls hais. Synthetic silica tuaj yeem ua tus nqa khoom rau cov kua lossis cov tshuaj paste, hloov cov kua viscosity siab rau hauv cov txheej txheem yooj yim thiab cov hmoov ntws dawb. Yog li ntawd, cov khoom muaj txiaj ntsig siab tuaj yeem sib cais. Tsis tas li ntawd, lawv tuaj yeem yooj yim tov nrog lwm cov khoom xyaw qhuav hauv txhua qhov kev faib ua feem. Nws muaj kev nqus siab, tsis muaj dej txaus, tshuaj lom neeg tsis muaj zog, thiab kev nyab xeeb ntawm lub cev.
