Qhov cuam tshuam tseem ceeb ntawm iav Hloov Kub Kub (Tg) ntawm Epoxy Resin: Xaiv cov khoom zoo rau kev ruaj ntseg
Nyob rau hauv siab - cov ntaub ntawv kev ua tau zoo, iav Hloov Kub Kub (Tg) yog qhov taw qhia tseem ceeb rau epoxy resin, txiav txim siab nws cov thermal resistance, mechanical stability, thiab daim ntawv thov ntau yam. Xaiv qhov zoo Tg tus nqi optimizes cov khoom ua tau zoo thiab cuam tshuam ncaj qha rau cov ntawv thov hauv fiber ntau optics, hluav taws xob encapsulation, thiab kev lag luam tsheb.
Iav Transition Temperature (Tg) yog dab tsi thiab Vim Li Cas Nws Tseem Ceeb?
Tg yog hais txog qhov kub thiab txias uas epoxy resin hloov los ntawm lub xeev khov iav mus rau lub xeev hloov tau yooj yim. Hauv qab Tg, epoxy resin khaws rigidity, siab mechanical zog, thiab qhov ntev stability; saum toj no Tg, nws softens, uas tej zaum yuav cuam tshuam hluav taws xob rwb thaiv tsev thiab structural kev ncaj ncees.
Tg cuam tshuam li cas Epoxy Resin Performance?
1. Thermal stability
Epoxy resin lub tshav kub kuj nyob ntawm nws tus nqi Tg:
High Tg (≥130 ° C) → Haum rau siab - qhov kub thiab txias ib puag ncig, xws li automotive electronics thiab fiber optic connector encapsulation.
Nruab nrab Tg (80 ~ 120 ° C) → Zoo tagnrho rau LED encapsulation thiab PCB potting, kom ntseeg tau ntev -lub sij hawm stability.
Tsawg Tg (50 ~ 80 ° C) → Haum rau kev tiv thaiv hluav taws xob tiv thaiv thiab qis - daim ntawv thov kub.
2. Mechanical Strength
High Tg epoxy resin muaj superior flexural zog thiab cuam tshuam tsis kam, ua rau nws zoo tagnrho rau siab -load daim ntaub ntawv: ✔ High Tg (≥130 ° C) → Zoo tshaj rau fiber optic connector encapsulation thiab automotive tivthaiv kev sib txuas.
✔ Nruab Nrab Tg (80 ~ 120 ° C) → Zoo tagnrho rau LED lens tiv thaiv thiab sensor encapsulation.
3. Hluav taws xob rwb thaiv tsev
Hauv kev siv hluav taws xob thiab fiber ntau optic, Tg cuam tshuam rau lub zog dielectric thiab qhov ntim tiv taus, ua kom ntev - lub sij hawm system stability: 📌 High Tg epoxy resin yog zoo tagnrho rau fiber optics, PCBs, thiab siab -voltage electronics.
📌 Medium Tg suits tus qauv hluav taws xob tiv thaiv encapsulation.
Cov ntawv thov zoo tshaj plaws rau Tg hauv Epoxy Resin Xaiv
📌 Fiber Optic Connector Encapsulation
✅ Pom zoo Tg: 130-150 ° C → Tswj kho qhov muag ruaj khov thiab tiv thaiv qhov kawg ntawm lub ntsej muag deformation.
📌 LED Lens Encapsulation
✅ Pom zoo Tg: 100-120 ° C → Ua kom pom qhov pom tseeb thiab ua haujlwm ntev.
📌 Automotive Electronics Encapsulation
✅ Pom zoo Tg: ≥140 ° C → Ua kom cov cua sov ua haujlwm thiab lub zog txhua yam nyob rau hauv siab - qhov kub thiab txias.
📌 PCB Potting & Txheej
✅ Pom zoo Tg: 80-120 ° C → Muab lub zog dielectric siab, haum rau cov ntawv siv hluav taws xob siab.
Yuav Ua Li Cas Xaiv Txoj Cai Epoxy Resin?
🔹 Xaiv Tg tus nqi raws li daim ntawv thov ib puag ncig (siab-kub vs. standard encapsulation).
🔹 Xav txog kev siv lub zog thiab kev rwb thaiv tsev kom ntseeg tau ntev -lub sij hawm.
🔹 Kom ntseeg tau tias qhov ntsuas qhov cuam tshuam cuam tshuam nrog kev siv kho qhov muag kom txo qis qhov muag pom.
