Cov khoom xyaw tseem ceeb ntawm basalt fiber infiltrant

1. Tus neeg sawv cev txuas

Tus neeg sawv cev txuas yog ib qho tseem ceeb rau kev kho mob uas muaj kev ruaj khov thiab kev laus tiv taus, feem ntau yog siv los ua tus pab rau cov khoom sib xyaw polymer, uas tuaj yeem muab faib ua plaub pawg loj raws li nws cov qauv tshuaj lom neeg thiab cov khoom sib xyaw: cov organic complexes, silanes, titanates, thiab aluminium acid compounds. Kev tsim cov neeg sawv cev txuas tshiab ua haujlwm siab yog ib qho ntawm cov ciam teb tshawb fawb hauv Iav Fiber Tus neeg sawv cev nkag mus rau hauv thaj chaw. Tus neeg sawv cev sib txuas txawv teb chaws ntxiv rau kev siv cov organic interface thiab inorganic interface coupling, kuj muaj lub luag haujlwm ua pawg sib txuas zaj duab xis, qee cov neeg sawv cev sib txuas kuj muaj cov nyhuv tiv thaiv hluav taws xob. Kev tshawb fawb tam sim no tsom mus rau kev tsim cov neeg sawv cev sib txuas tshiab uas tuaj yeem ua kom zoo dua cov khoom siv sib txuas thiab txhim kho lub zog sib txuas. Cov kws tshawb fawb tab tom tshawb nrhiav ntau yam tshuaj lom neeg thiab cov qauv tsim khoom tshiab los txhim kho kev sib raug zoo ntawm interfacial, affinity thiab bond strength kom ua tiav kev sib raug zoo ntawm interfacial. Tam sim no feem ntau siv dav yog lithane coupling agents thiab titanate coupling agents. Tus neeg sawv cev sib txuas lithane muaj ob txoj hauv kev tseem ceeb: thawj zaug, nws tuaj yeem ua rau muaj kev sib txuas nrog pawg hydroxyl hauv cov khoom siv inorganic los tsim cov tshuaj sib txuas, yog li ua kom zoo sib xyaw cov organic thiab inorganic theem ua ke thiab txhim kho qhov adhesion thiab affinity ntawm qhov interface; qhov thib ob, tus neeg sawv cev sib txuas lithane tuaj yeem cuam tshuam nrog cov saw hlau ntev hauv cov khoom siv organic los txhim kho kev sib raug zoo thiab kev sib txuas ntawm cov polymer thiab cov inorganic filler, thiab txhim kho kev ua tau zoo ntawm cov khoom siv. Thaum tus neeg sawv cev sib txuas titanate cuam tshuam nrog cov protons dawb (H +) ntawm qhov interface ntawm cov tshuaj inorganic, ib txheej organic monomolecular tau tsim. Cov txheej organic monomer no tuaj yeem tsim ib txheej npog rau ntawm qhov chaw filler thiab cuam tshuam nrog cov polymer, yog li ua rau kom muaj kev sib txuas thiab kev sib txuas ntawm cov polymer thiab cov filler. Kev ntxiv cov neeg sawv cev titanate rau cov polymers tuaj yeem ua rau lub zog cuam tshuam ntawm cov khoom siv ntau ntxiv. Tsis tas li ntawd, cov fillers tuaj yeem ntxiv rau hauv qhov ntau ntawm 50% lossis ntau dua yam tsis muaj kev sib cais theem, uas tswj tau qhov sib xws thiab kev ruaj khov ntawm cov khoom siv.

2. Cov roj nplua nyeem thiab cov neeg sawv cev tiv thaiv hluav taws xob

Thoob ntiaj teb hauv kev tsim cov tshuaj infiltrant, cov roj nplua nyeem thiab cov neeg sawv cev antistatic feem ntau yog sib xyaw ua ke. Cov roj nplua nyeem feem ntau yog cov saw ntev aliphatic imidazoline lossis cov kua qaub uas muaj ob daim ntawv cog lus thiab cov cawv ntev monohydroxy esters, feem ntau yog siv los tswj cov viscosity ntawm cov tshuaj infiltrant, txo nws qhov kev ntxhov siab ntawm qhov chaw, yog li nws tau faib sib npaug ntawm qhov chaw ntawm cov khoom kho, los txhim kho lub luag haujlwm ntawm infiltration. Nanolubricants tau yog ib qho kev tshawb fawb kub hauv xyoo tas los no, thiab coated Basalt Cov fibers tsis yog tsuas yog muaj kev ua haujlwm tiv thaiv kev hnav siab xwb tab sis kuj ua tiav qhov cuam tshuam ntawm kev txo kev sib txhuam. Cov kws tshawb fawb tab tom tshawb nrhiav kev siv cov nanoparticles hauv cov roj nplua nyeem los txhim kho kev sib txhuam thiab kev hnav ntawm cov ntaub ntawv. Nyob ntawm lawv lub luag haujlwm, cov roj nplua nyeem tuaj yeem faib ua ob hom: sab hauv thiab sab nraud.
