环氧樹脂地坪固化的三個階段怎麼分?
环氧樹脂固化劑是與环氧樹脂發生化學反應,形成網狀立體聚合物,把復合材料骨材包絡在網狀體之中。 使線型樹脂變成堅韌的體型固體的添加劑。包括多種類型。环氧地坪多用於地下車庫地面,價格便宜實用。下面我們就來瞭解一下环氧樹脂固化的三個階段.這時新使用的环氧樹脂不能與它進行化學鏈接,因為該环氧表面必須適當地進行預處理如打磨,才能得到好的粘接機械強度。
The curing agent of epoxy resin reacts with epoxy resin to form a reticulated stereo polymer, which encapsulates the composite material in the reticulate. Make linear resin a tough solid solid additive. It includes many types. The epoxy floor is used in the underground garage floor, the price is cheap and practical. Here's a look at the three stages of curing of epoxy resin, when the new epoxy resin can't be chemically linked to it, because the epoxy surface must be properly pre-treated, such as grinding, to obtain good bonding mechanical stren透水地坪gth.
1、液體-操作時間
1. Liquid operating time
操作時間(也是工作時間或使用期)是固化時間的一部份,混合之後,樹脂/固化劑混合物仍然是液體和可以工作及適合應用。為瞭保證可靠的粘接,全部施工和定位工作應該在固化操作時間內做好。
Operating time (also working time or service life) is part of the curing time. After mixing, the resin/curing agent mixture remains liquid an环氧地坪d can work and be suitable for use. In order to ensure reliable bonding, all construction and positioning work should be done during curing time.
2、凝膠-進入固化
2, gel - curing
混合物開始進入固化相(也稱作熟化階段),這時它開始凝膠或“突變”。這時的环氧沒有長時間的工作可能,也將失去粘性。在這個階段不能對其進行任何幹擾。它將變成硬橡膠似的軟凝膠物,你用大拇指將能壓得動它。
The mixture begins to enter the curing phase (also known as ripening stage), when it begins to gel or "mutate". Epoxy does not work for a long time and may lose viscosity. No interference can be made at this stage. It will turn into a hard rubber soft gel, and you will be able to press it with your thumb.
因為這時混合物隻是局部固化,新使用的环氧樹脂仍然能與它化學鏈接,因此該未處理的表面仍然可以進行粘接或反應。無論如何,接近固化的混合物這些能力在減小。
Because the mixture is only partially cured, the newly used epoxy resin can still be chemically linked to it, so the untreated surface can still be bonded or reacted. In any case, these abilities close to the solidified mixture are decreasing.
3、固體-最終固化
3. Solid final cure
环氧混合物達到固化變成固體階段,這時能砂磨及整型。這時你用大拇指已壓不動它,在這時环氧樹脂約有90%的最終反應強度,因此可以除去固定夾件,將它放在室溫下維持若幹天使它繼續固化。
The epoxy mixture can be solidified to solid stage, and then it can be sanded and shaped. You can't press it with your thumb. At this point, the epoxy resin has about 90% of the final reaction strength, so you can remove the fixture and put it at room temperature for a few days to keep it solidified.
