Krachtig vuurvast beton voor smidsvuren en ovens, bestand tegen temperaturen tot 1650°C. Deze hittebestendige beton wordt geleverd in een zak van 5 kg, 10 kg of 25 kg en is ideaal voor zowel kleine reparaties als grotere projecten.

Toepassing en gebruik

Deze vuurvaste beton is ontwikkeld voor de bouw en reparatie van smidsvuren en gasovens die aan extreme hitte worden blootgesteld. Met een maximale bestendigheid tot 1650°C biedt het materiaal uitstekende warmteopslag en een hoge weerstand tegen temperatuurschommelingen. Ook in contact met borax en andere vuur lasmiddelen blijft het hittebestendige beton sterk en duurzaam.

Verwerking

Het beton is hydraulisch gebonden en eenvoudig aan te maken met water (ca. 0,06 liter per kg). Na een mengtijd van circa 5 minuten kan het materiaal worden verwerkt. Je hebt ongeveer 20 minuten verwerkingstijd, waarna het materiaal begint uit te harden. Voor een optimale warmteopslag wordt een laagdikte van 10–20 mm aanbevolen. In zwaar belaste zones kan een dikkere laag nodig zijn.

Uitharding en inbranden

Na het aanbrengen moet het beton 1–2 weken in de bekisting blijven, beschermd tegen vorst en tocht, zodat deze rustig kan drogen. Voor de eerste ingebruikname is een zorgvuldig inbrandproces nodig: de smeedoven of smidsvuur langzaam opstoken op de laagste vlam. Zodra er damp ontsnapt, het vuur doven en opnieuw beginnen zodra de damp verdwenen is. Dit proces herhalen totdat er geen damp meer vrijkomt. Daarna de temperatuur stap voor stap opvoeren tot de maximale gebruikstemperatuur.

Veiligheid

Bij de verwerking is het belangrijk om goede voorzorgsmaatregelen te nemen:

  • Bescherm het product tegen vocht tijdens opslag.
  • Vermijd het inademen van stof.
  • Gebruik ademhalingsbescherming bij onvoldoende ventilatie.
  • Bij huid- of oogcontact: direct met veel water spoelen.

Decent for the price. Instructions suck but most people should be able to figure it out. More below.
Color: Black, Size: 6 Panel, Color: Black, Size: 6 Panel
SUMMARY: 3 stars from me because it's firmly average. It's fine for the price. Assembly and materials are alright but I can see some caveats depending on your circumstances. Assembly instructions do a subpar job of pointing out some details. ASSEMBLY INSTRUCTIONS: Maybe it's because I'm autistic and/or building model kits and assembling stuff is my jam, but I honestly thought people were exaggerating when they were complaining about the instructions and I'd be able to flex my ~superior assembly skills.~ I was wrong! These instructions genuinely suck, and whoever is responsible for making them should be ashamed. The instructions do a poor job of calling out some details regarding orientation of parts, and some of the images do not actually match the physical parts. For example, it does not really outline the assembly of the end panels clearly, and I can see someone accidentally using the wrong poles. I've drawn over a photo to show what you should do to try and make it clearer. Additionally, the manual shows a flathead screw for bolting the feet into position, but the actual screw is not a flathead. It also does not point out the counterbore, so if you aren't paying attention you may put the foot pads onto the wrong side of the foot. It's also missing the fact that you need to use another one of the plastic pieces when you finish assembling a panel. ACTUAL ASSEMBLY & MATERIALS: To their credit, all of my bags were clearly labeled. The assembly process wasn't difficult. It's mostly just tedious and requires a fair amount of space. I was able to assemble it by myself without any real difficulty. However, the way it's assembled means two things. One, the fabric parts aren't removable without disassembly. So if you want to use this in an environment where they would require cleaning, I would seriously recommend looking for another option. Or, you could buy this just to use the frame pieces and then somehow buy or make your own fabric pieces designed to be removable with velcro or something. Two, because of the materials I really don't have a lot of faith in this thing surviving disassembly and reassembly. Like a lot of sorta-cheap-but-convenient furniture, it uses those spring-button connections and plastic inserts with self-tapping screws. Those things are not really meant to be disassembled and rethreaded. It also relies a lot on the tension of the poles and the fabric to keep everything rigid and squared, which I think puts a lot of pressure on the aforementioned buttons, plastic inserts, and the hollow metal rods. So I feel like that will also cause issues with disassembly and reassembly. Basically once this thing is assembled, it's not really meant to be disassembled. The best you can do is spot-clean the fabric if you need to. Speaking of the fabric, I didn't see any labels on them or anything in the manual that says what they are, but they feel like some kind of polyester. They generate static electricity pretty easily, and pet hair and debris sticks easily. So that's another downside of them not being easily removable. For the most part it does seem pretty stable. The poles seem to be pretty uniform in length so they're all making contact with my floor. Obviously this isn't structural so it shouldn't be supporting anything, but the two main feet seem to be doing fine with keeping this thing upright. CLOSING THOUGHTS: Really, it's fine for what it is, but it could be better in a lot of little ways and the substandard quality of the instructions just seems unprofessional to me, which is why I'm being so harsh with my rating. Depending on your needs and environment you may want to consider a different option. Preferably one that is made to be disassembled with better materials, and/or one with fabric pieces made to be removed easily.

Not as it seems
Color: Black, Size: 6 Panel
these are awful... Each individual panel is fine, but when you put it together it can barely stand up, and the clips that hold it together keep popping off. Steer clear of this item.

Great Product that does exactly what it says it will.
Color: Beige, Size: 34"- 3 Panel
I really enjoy this product and it does exactly what it describes. I use it on my balcony. It is effective, but still very lightweight. It is easy to assemble as well. The price point is excellent. Also, I had an interaction with the company about an issue and they were incredibly responsive and helpful, fixing the issue immediately. Highly recommend.

Great WFH screen for video calls
Color: Black, Size: 22"- 4 Panel
I share a workspace with my hubs since we both work from home. I have the attention span of a 🐿️ and need this so I can focus on my work and not get distracted by him, since he is very amusing to watch. This screen is very lightweight and the panels can move and create a little cubicle around your workspace. I personally loved cubicles & despise open space seating, even at home. The ADHDer in my loves being able to block things away from my field of vision. These panels also hide any mess behind you, especially if you forget to blur the background on Teams or Zoom calls or if you don’t have the option to change your backgrounds. This was fairly easy to put together and very easy to move and adjust. The screen is a much better option than a sheet as I’ve seen others use on calls.🤦🏻‍♀️😂 I’m not sure how it will stand up around rambunctious pets or kids, but fairly certain it takes quite a push to knock it over. We have four cats & I’m pretty sure someone would try to climb this, which is why they’re not allowed in our workspace.
