Basalt fiber infiltrant cov khoom xyaw tseem ceeb

1.Coupling agent

Tus neeg sawv cev sib txuas yog tus neeg saib xyuas kev kho mob tseem ceeb nrog kev ua haujlwm zoo thiab kev laus ua haujlwm, feem ntau yog siv los ua ib qho kev pabcuam rau cov khoom siv polymer, uas tuaj yeem muab faib ua plaub pawg loj raws li nws cov qauv tshuaj thiab muaj pes tsawg leeg: organic complexes, silanes, titanates, thiab aluminium acid compounds. Tsim cov tshiab high-efficiency coupling tus neeg saib xyuas yog ib qho ntawm cov kev tshawb fawb frontiers nyob rau hauv lub iav Fiber infiltration agent teb. Txawv teb chaws coupling tus neeg sawv cev ntxiv rau cov organic interface thiab inorganic interface coupling siv, kuj muaj ib tug zaj duab xis bonding pawg, ib co coupling agents kuj muaj ib tug lubricating antistatic nyhuv. Kev tshawb fawb ntawm tus neeg sawv cev txuas tam sim no tsom mus rau kev tsim cov khoom sib txuas tshiab uas tuaj yeem txhim kho cov khoom sib txuas thiab txhim kho kev sib raug zoo. Cov kws tshawb fawb tab tom tshawb nrhiav ntau yam ntawm cov tswv yim tshuaj thiab cov khoom siv tshiab tsim los txhim kho kev sib raug zoo ntawm kev sib raug zoo, kev sib raug zoo thiab kev sib koom ua ke kom ua tiav kev sib raug zoo ntawm kev sib raug zoo. Tam sim no feem ntau siv yog lithane coupling agents thiab titanate coupling agents. Tus neeg sawv cev lithane coupling muaj ob lub ntsiab lus tseem ceeb: ua ntej, nws tuaj yeem hnov ​​​​mob nrog hydroxyl pawg hauv cov khoom siv inorganic los tsim cov tshuaj lom neeg, yog li kev sib txuas cov organic thiab inorganic theem ua ke thiab txhim kho cov adhesion thiab affinity ntawm lub interface; Thib ob, tus neeg sawv cev lithane tuaj yeem cuam tshuam nrog cov saw ntev molecular hauv cov khoom siv organic los txhim kho kev sib raug zoo thiab kev sib raug zoo ntawm cov polymer thiab cov khoom siv inorganic, thiab txhim kho kev ua haujlwm ntawm cov khoom. Thaum cov titanate coupling tus neeg sawv cev reacts nrog dawb protons (H +) ntawm lub interface ntawm inorganic tshuaj, ib tug organic monomolecular txheej yog tsim. Cov organic monomer txheej no tuaj yeem tsim cov txheej txheej ntawm qhov chaw muab tub lim thiab cuam tshuam nrog cov polymer, yog li ua kom cov adhesion thiab kev sib txuas ntawm cov polymer thiab cov muab tub lim. Qhov sib ntxiv ntawm titanate coupling tus neeg sawv cev rau cov polymers tuaj yeem ua rau muaj kev cuam tshuam lub zog ntawm cov khoom. Tsis tas li ntawd, cov fillers tuaj yeem muab ntxiv rau hauv cov nyiaj ntawm 50% lossis ntau dua yam tsis muaj kev sib cais, uas tswj cov homogeneity thiab ruaj khov ntawm cov khoom.

2.Lubricants thiab antistatic neeg sawv cev

Thoob ntiaj teb nyob rau hauv formulation ntawm infiltrant, lubricants thiab antistatic agents feem ntau ua ke rau hauv ib tug. Lubricants feem ntau yog cov saw ntev ntev aliphatic imidazoline los yog cov kua qaub uas muaj ob daim ntawv cog lus thiab cov hlua ntev ntev monohydroxy esters, feem ntau yog siv los tswj cov viscosity ntawm cov tshuaj infiltrant, txo nws qhov nro ntawm qhov chaw, thiaj li hais tias nws yog uniformly faib rau saum npoo ntawm cov khoom kho, txhim khu lub luag hauj lwm ntawm infiltration. Nanolubricants tau yog lub ntsiab lus tshawb fawb kub hauv xyoo tas los no, thiab coated Basalt fibers tsis tsuas yog muaj kev ua tau zoo los tiv thaiv kev hnav, tab sis kuj ua tiav cov txiaj ntsig ntawm kev txo kev sib txhuam. Cov kws tshawb fawb tab tom tshawb nrhiav kev siv nanoparticles hauv lubricants los txhim kho kev sib txhuam thiab hnav cov khoom ntawm cov khoom. Nyob ntawm lawv lub luag haujlwm, lubricants tuaj yeem faib ua ob hom: sab hauv thiab sab nraud. Lub Cheebtsam ntawm cov lubricants sab hauv yog cov khoom siv polymer, xws li siv quav ciab, polyolefins, thiab lwm yam, uas muaj kev sib raug zoo, tuaj yeem txo cov cohesion ntawm polymer molecules, thiab txhim kho cov kev sib txhuam thaum tshav kub kub tsim tshwm sim nyob rau hauv lub yaj thiab yaj fluidity, ua kom nws muaj txiaj ntsig zoo hauv extrusion, txhaj molding thiab lwm yam kev ua. Cov muaj pes tsawg leeg ntawm lub lubricant sab nraud yog cov tsis tshua muaj molecular tebchaw, xws li fatty acid esters, paraffin wax, thiab lwm yam, uas tuaj yeem txhim kho kev sib txhuam ntawm cov yaj thiab cov khoom siv, txo cov kev sib txhuam coefficient ntawm txhua txoj kev tsim khoom, ua lub luag haujlwm tseem ceeb hauv kev sib xyaw, calendering, qab zib molding, thiab lwm yam txheej txheem molding. Antistatic cov neeg sawv cev tuaj yeem muab faib ua ob pawg: inorganic thiab organic, thiab lawv lub luag haujlwm tseem ceeb yog tsim txoj hauv kev ntawm cov yeeb yaj kiab infiltrant, tso tawm cov nqi hluav taws xob uas tsim los ntawm fiber ntau hauv kev tsim khoom thiab siv cov txheej txheem. Qhov sib ntxiv ntawm nanofillers (xws li, carbon nanotubes, graphene, thiab lwm yam) rau cov polymer matrix tuaj yeem txhim kho cov conductivity thiab antistatic zog ntawm cov khoom. Nyob rau hauv xyoo tas los no, cov kws tshawb fawb tau mob siab rau tshawb nrhiav kev sib cuam tshuam ntawm ntau yam nanofillers thiab polymer matrices kom tau txais cov khoom zoo dua qub.

3.Film-forming tus neeg saib xyuas

Raws li qhov tseem ceeb tshaj plaws nyob rau hauv tus neeg sawv cev infiltrating, zaj duab xis-forming tus neeg saib xyuas txiav txim siab kev ua tau zoo thiab cov khoom ua tau zoo ntawm basalt fiber ntau. Nyob rau hauv cov txheej txheem ntau lawm ntawm basalt fiber, yog kuj ua kom tiv thaiv cov khoom sib txuam, ua kom muaj kev sib txuam ntawm cov pob zeb uas muaj zog, txhawm rau kom muaj kev ncaj ncees ntawm cov fiber. Tsis tas li ntawd, tus neeg sawv cev ua yeeb yaj kiab tuaj yeem muab cov basalt fibers xws li gloss, mos, du thiab lwm yam khoom tshwj xeeb thiab cov tsos. Nanomaterials kuj tau siv dav hauv kev tshawb fawb ua yeeb yaj kiab. Nws tau raug pom tias qhov sib ntxiv ntawm nanoparticles tuaj yeem txhim kho lub cev muaj zog ntawm cov yeeb yaj kiab tsim cov neeg ua haujlwm, xws li kev txhim kho kev puas tsuaj, huab cua thiab cov khoom siv kho qhov muag.

4.pH Hloov kho

Lub pH regulator tuaj yeem kho cov acidity thiab alkalinity ntawm infiltrant kom nws tsim nyog rau kev cuam tshuam nrog basalt fibers. Los ntawm kev kho cov pH ntawm infiltrant, tus nqi them tus yam ntxwv ntawm lub fiber nto tuaj yeem hloov tau los txhawb kev sib cuam tshuam quab yuam ntawm cov infiltrant thiab fiber, yog li txhim kho cov infiltration kev ua tau zoo ntawm cov fiber ntau. Nws tau raug qhia tias nanomaterial-based pH modulators tuaj yeem muab kev hloov kho siab dua thiab ua haujlwm tau zoo. Tsis tas li ntawd, muaj kev tshawb fawb txog PH regulators rau ntau hom fiber ntau thiab kev ua haujlwm, nrog rau kev pom kom tau txais fiber ntau wetting zoo dua thiab kev ua haujlwm.

5.Lwm yam khoom

Impregnants kuj muaj biocides, emulsifiers, defoamers, thiab lwm yam, uas yog siv los tua cov kab mob, tswj kev sib raug zoo thiab kev ruaj ntseg ntawm cov khoom, thiab tiv thaiv kev tsim thiab tsub zuj zuj ntawm cov npuas dej.
