Mene ne bambanci tsakanin FR4 epoxy fiberglass board da kuma 3240 epoxy fiberglass allo?

A gida epoxy fiberglass jirgin yawanci 3240, kuma FR4 epoxy fiberglass board is generally imported insulation board. But both are very different things from physical properties or chemical properties. Let me introduce it to everyone briefly:

1, 3240 epoxy gilashin fiber allo, janar cikakken suna: 3240 epoxy phenolic fiberglass zane laminate. Yana amfani da manne epoxy resin manne da kayan phenolic azaman wakili na warkewa. Yawan zafin jiki yana da digiri 155. Mafi kyawun aikin inji. Hakanan ya dace sosai da transfoma da mai. Yawan yawa gabaɗaya baya wuce ma’auni na ƙasa: 1.9.

However, many domestic manufacturers now participate in fillers, such as talcum powder, in order to save costs in the production process. Their density has increased dramatically. It also greatly reduces electrical performance. It is only suitable for general insulation projects.

2. FR4 epoxy glass fiber board. Epoxy glue is used. But it is not a curing agent with phenolic materials. Purely cured at high temperature. It is compared with plastic pure. The temperature is usually greater than 180 degrees. The machining performance is very strong. A colleague once joked that cutting with a cutting machine cuts sparks.

yana nuna aikin sarrafa shi. Kuma ba zai tsage ko lalata ba lokacin amfani da shi. Ayyukan lantarki yana da ƙarfi sosai. Ya dace da allunan kewayawa na lantarki da laminates masu suturar jan ƙarfe. Kayan tushe na iya zama duka kyalle mai kyau. Tufafin fiber na lantarki. Yawanci yana da yawa na 1.85. Juriya ga lalata sinadarai.

3240 epoxy fiberglass board da FR4 epoxy fiberglass board sune manyan allunan fiberglass na epoxy guda biyu na yau da kullun akan kasuwa. Kowa yace FR4 yafi 3240. Menene banbancin su?

Bambanci 1: FR4 yana da kyakkyawan aikin jinkirin wuta.

FR4 shine ingantaccen samfurin 3240 epoxy gilashin fiber allo. Aiki retardant na harshen wuta na FR4 epoxy gilashin fiber allo hadu da kasa UL94V-0 misali. 3240 epoxy gilashin fiber allon ba shi da wani harshen retardant Properties.

Bambanci na 2: Farin launi.

The color of FR4 is very natural, a bit jade, and the color of 3240 epoxy fiberglass board is a bit blinking. It doesn’t look very natural. Most of the colors are not very uniform.

Difference three: FR4 has no radiation and is environmentally friendly.

3240 epoxy gilashin fiber allo yana dauke da halogen, wanda ba shi da mutunta muhalli sosai ga muhalli da jikin mutum. Har ila yau, bai dace da dabarun ci gaba mai dorewa na kasar ba. FR4 epoxy gilashin fiber allon shine kawai akasin haka.

Bambanci 4: FR4 yana da kwanciyar hankali mai girma.

FR4 yana da mafi kyawun kwanciyar hankali fiye da 3240, kuma yayin aiwatar da latsawa, haƙurin kauri na FR4 shima ya fi 3240, wanda ya fi dacewa da sarrafawa.

Bambanci na biyar: FR4 na iya kashe kansa daga wuta.

Za a iya kashe FR4 ta halitta idan wuta ta kama.

bambanci shida: ƙarancin sha ruwa.

Ruwan ruwansa (D-24/23, kaurin farantin 1.6mm): ≤19mg, wanda ke ba da taimako mai kyau don amfani da shi a cikin rigunan wuta da sauran kayan aiki.

Because FR-4 epoxy glass fiber board has very good performance, it is now used as a material for insulating parts in the electrical and electronic industries. Of course, 3240 epoxy fiberglass board still has a certain market due to its price advantage.
