Fiberglass Surface Treatment Method - Acid Thiab Alkali Etching Treatment Technology

Lub ntsiab Cheebtsam ntawmfiberglasssuav nrog oxides ntawm cov ntsiab lus xws li silicon oxide, aluminium oxide, calcium magnesium sodium, thiab lwm yam oxides. Cov oxides nyob rau saum npoo ntawm cov fiber ntau tuaj yeem kho nrog cov kua qaub los yog alkali tsim nyog los txhim kho qhov roughness ntawm nto etching. Cov kev nyuaj siab thiab micropores tsim nyob rau hauv txoj kev no pab txhim kho lub interfacial bonding zog ntawm fiber thiab matrix los ntawm lub thiaj li hu ua "locking effect"; Tsis tas li ntawd, acid-base etching tseem tuaj yeem tsim cov pab pawg hydroxyl nyob rau saum npoo ntawm cov fiber ntau, ua rau ntau ntawm Si-OH bonds. Thaum lub matrix yog compounded, lub hav zoov ntawm lub functional pab pawg neeg Si-OH ua rau saum npoo ntawm fiber muaj ib tug tej yam reactivity. Hauv cov txheej txheem organic tsim nyog, Si-OH tuaj yeem cuam tshuam nrog cov pab pawg ua haujlwm ntawm cov khoom siv polymer, thiab cov tshuaj sib xyaw ua ke tuaj yeem txhim kho cov txiaj ntsig ntawm kev siv zog thiab cov organic sib txuas. Kev kho mob ntawmfiberglasslos ntawm acid-base etching tuaj yeem txhim kho kev ua tau zoo ntawm cov ntaub ntawv sib xyaw, tab sis kev siv cov cuab yeej no yuav tsum muaj kev tswj xyuas cov txheej txheem ntawm cov kua qaub-puag etching, txwv tsis pub etching kev kho tsis tsim nyog yuav txo tau cov neeg kho tshuab lub zog ntawm cov iav fiber ntau rau qhov sib txawv, ua rau poob ntawm cov txiaj ntsig zoo heev. Sun Wenqiang et al. siv alkali los kho qhov chaw ntawm iav fiber. Vim muaj cov nyhuv corrosion muaj zog thiab qib ntawm corrosion tsis yooj yim los tswj, lub zog ntawm iav fiber ntau txo qis. Txawm li cas los xij, kev kho mob nrog dilute hydrochloric acid thiab dilute sulfuric acid tuaj yeem ua rau lub ntsej muag roughness thiab ua kom zoo dua qhov chaw ntawm cov fiber ntau, yog li txhim kho cov iav fiber ntau. Lub wettability ntawm fiber ntau thiab resin matrix, tab sis tom qab cov kua qaub thiab alkali etching, yog tias kev kho mob tsis ua kom zoo, qhov saum npoo ntawm fiber ntau yuav corroded ntau dhau, uas yuav ua rau muaj kev ntxhov siab thiab txo lub zog ntawm fiber ntau.
