【Siv】
THFA yog cov khoom siv acrylate nrog lub nplhaib tetrahydrofuran. Tetrahydrofuran yog ib chav kawm ntawm heterocyclic organic tebchaw thiab chav kawm ntawm cyclic ethers uas muaj zog polarity. Nws tuaj yeem siv los ua cov kuab tshuaj nruab nrab-polarity hauv tshuaj tiv thaiv thiab kev rho tawm. Qhov muaj zog polarity coj los ntawm pawg tetrahydrofuran ua rau cov khoom no muaj zog adhesion rau feem ntau cov ntaub ntawv, thiab txawm muaj qhov o ntawm qee cov yas xws li PC.PET. THFA kuj tseem muaj huab cua tsis zoo, ua kom daj tsis kam, dej tsis kam, dilution kuj thiab yoog raws. THFA tau pom zoo rau ntau cov nplaum, xws li cov substrate UV nplaum tshwj xeeb; tshwj xeeb substrate inks thiab resins, emulsion polymerization. Cov ntsiab lus yog raws li nram no:
Chemical intermediates: siv los npaj ntau yam organic compounds, xws li resins, coatings, plastics, dyes thiab tshuaj.
Polymer kev lag luam: raws li ib tug crosslinker, plasticizer thiab stabilizer.
Adhesives: hnov mob nrog cov khoom xws li phenoxyethyl methacrylate los npaj binary adhesives uas tuaj yeem ua raws li qhov kub thiab txias.
UV inks: compounded nrog polyurethane resins, thiab lwm yam, los npaj kev tshuaj ntsuam luam ntawv UV inks los txhim kho cov teeb meem luam ntawv ntawm qee cov ntaub ntawv.
Membrane Cheebtsam: siv los ua cov khoom siv potting rau cov khoom siv membrane los txhim kho kev ua haujlwm ntawm hollow fiber membrane cov khoom.
Dej-boiled kua nplaum: sib xyaw nrog lwm cov khoom siv los npaj cov kua nplaum ib leeg los txhim kho silicon wafer efficiency.
UV curing coatings: raws li active diluents, siv los npaj UV curing txheej, siv rau graphite tshav kub dissipation cov ntaub ntawv, thiab lwm yam.
Tshwj xeeb acrylate: Thaum siv nrog cov amino resin, nws tuaj yeem kho tau ntawm qhov kub thiab txias thiab muaj cov nyhuv plasticizing.
Lub teeb-kho cov khoom: Raws li monomer diluent, nws yog siv nyob rau hauv UV-kho nplaum nplaum, coatings, inks thiab lwm yam teb. Vim nws cov qauv tshwj xeeb, nws muaj adhesion zoo rau lub substrate.
