Kev siv ntawm 1,4-butanediol diglycidyl ether
1,4-Butanediol diglycidyl ether (BDDGE) yog ib qho tshuaj diluent uas muaj ob yam haujlwm ua ke nrog epoxy resin, siv dav hauv kev lag luam txheej thiab kev lag luam tshuaj lom neeg. Nws muaj cov yam ntxwv ntawm kev ywj pheej zoo, viscosity tsawg, volatility tsawg, tsw tsawg, thiab tsis muaj tshuaj lom. Nws feem ntau yog siv los ua diluent rau epoxy resin los txo qhov viscosity ntawm epoxy system thiab txhim kho cov khoom siv kho tshuab ntawm epoxy kho khoom.

Tshwj xeeb, BDDGE siv dav hauv cov teb hauv qab no:

Kev Lag Luam Txheej Txheem: Ua ib qho epoxy reactive diluent, BDDGE tuaj yeem txo qhov viscosity ntawm lub kaw lus epoxy, txhim kho kev nkag mus ntawm lub kaw lus epoxy resin thaum lub sijhawm casting, thiab tau txais kev muaj peev xwm ntub dej zoo thaum lub sijhawm lamination thiab bonding.

Kev lag luam tshuaj lom neeg: BDDGE siv tau nrog bisphenol A-hom epoxy resin los npaj cov nplaum, cov yas cam khwb cia, cov kua impregnation, thiab lwm yam.
Tshuaj thiab tshuaj txhua hnub: BDDGE tuaj yeem tsim cov ether bonds nrog hyaluronic acid thiab tuaj yeem siv ua tus neeg sawv cev sib txuas hauv cov teb ntawm kev kho mob zoo nkauj, tshuaj txhua hnub, tshuaj thiab lwm yam teb kom tau raws li kev xav tau tiv thaiv kev laus.
Ntxiv rau, muaj ntau txoj kev npaj rau BDDGE, suav nrog ib kauj ruam, ob kauj ruam, theem hloov catalysis txoj kev, olefin oxidation txoj kev, thiab lwm yam.
