Product Description
This screw rod is made from 99.5% alumina ceramic materials, the use of dry pressing process makes the rod obtain high density and good flexural strength, resulting in better acid corrosion.
On the threaded portion, we use the machining way to make more precise thread size. The thread out of Such processing will get the same accuracy and with metal thread.
We can manufacture products according to your needs, the more common specification is 271mm, below are some of our existing specification.

- Q:Why dont they crush down to littel peices and then too dust unwanted concrete and re sell it in bags ready to be used again by just adding water ?The same thing with ceramics , someone told me they dont do it with ceramics becuase it causes a disease called silicoses or something like that .please excuse the sorry spelling .
- every player has different preferences (for example how they tape their stick, size, weight, color, brand, etc.) the cap at the top is simply a grip aspect. if you leave it on and tape over it you have a little barrier to prevent your hands from falling of the stick at the end
- Q:Why they used the ceramic material.
- the whole point of putting out a fire with water is to keep oxygen from burning because fire needs oxygen to burn when you try to put out a jet fuel fire all your doing is spreading the fuel around without stopping the oxygen from burning. the best way to put out a jet fuel fire or oil fire is to beat it with a towel or blanket trust me it works
- Q:I bought black spots (spots) on the pottery. How can I get rid of this black spot?
- Go away ~ don't suck, optimistic about the next time on the line
- Q:what is ceramic bearings?
- you pop the master cylinder brake lid off then crack the bleeder screw on the farthest wheel away and let it bleed. After its running clear tighten it up then crack the next one loose then do the fronts closer to the wheels. i hope i didn't confuse you. haha hope it helps
- Q:Is it okay to use a ceramic heat emitter for my red eared slider hatchlings instead of a normal basking bulb? I am in a college dorm and we are not allowed to use halogen lightbulbs. I do have a UV bulb and a temporary halogen basking bulb. Do you have any suggestions for something other than a halogen bulb?
- A ceramic heat emitter may not draw your turtles to the basking area, since they respond more to light than heat. You can use a regular 60 watt household incandescent light bulb (not the curly type) as a basking bulb. It doesn't run as hot as halogen bulbs, which aren't allowed in some college dorms because they can be a fire hazard.
- Q:Just wondering if there are any problems letting my cats eat off of ceramic dishes (my regular dishes).
- Are ceramic dishes ok for pets? - Yes, as long as the the glazes used do not contain lead. Many vets tell you not to use plastic dishes because some of the chemicals can leach out and cause problems like acne. Ceramic without lead in the glaze, stainless steel or glass are all usable with cats - or any animal for that matter. Go with the heaviest bowls you have to avoid, as much as possible, them being turned over if you have a cat who paws at bowls before or after eating. We have several cats and to keep from having to wash a lot of bowls, we use paper plates for canned food. We buy the cheapest we can find and toss them when the food is gone or it is apparent that no one is going to lick off whatever little might remain.
- Q:I‘m thinking of buying one for my hedgehog, but my question is. Since my cage setup is two sterlite bins connected with a tube, do you think the emitter would be able to heat both bins?
- Heating pet cages is interesting question. Claire's rabbits were banished to the garage, which gets quite cool at night in the winter. We got a small heater with a fan and a thermostat, put walls near the cage, and the heater near the cage. The fan would blow warm air towards the bunnies, keeping that corner of the garage warm. This is better, I think, than a purely radiative (no fan ceramic) type, because the ceramic heater will warm the sterite contaner it is pointed to. This will not be efficient, and could be a fire hazard. Put it on a GFI circuit for safety. I also put a light on a timer so it was on during the day. Turn the thermostat relatively cool. You can also put a cheap thermometer there. Rodents are supposedly ok to near freezing temps, but we kept their cages above 55°F, since they can't snuggle in their insulating dens the way they do in the wild. Our bunny cage is open, so air can circulate. Air circulation is probably not good inside your sterite containers, but if you keep the outside reasonably warm, the inside will be too. Important to keep cages out of the wind if you want to keep them warm.
- Q:I want to to decorate ceramic plates, but I still want to be able to eat off them. I want to decorate it with some form of a transfer sticker onto the plate. does anyone know: 1. Is there any kind of sticker that exists that can be placed on a ceramic plate that won‘t peel or fade?2. If there is, is there anyway of designing your own sticker?
- If you can find a local pottery shop, they should be able to help you. Generally, ceramic plates are decorated and then coated with a liquid paint-like substance called glaze or glazing which is then heated in a kiln (a process called 'firing'). You can paint directly on the plate, let it dry, and then coat with glaze. The glaze turns into a glass-like surface, and it's what covers probably every ceramic plate, bowl, or cup you've ever eaten or drank from. The decals are a little trickier. That are some decals made for use with ceramics, but they are special in that that can tolerate the heat of firing. Personally, I'd go with painted.
- Q:what is better glass or ceramic cooktops I need pros cons with brand name as well please. ) Thanks
- i purchased a GE ceramic accurate range about 3 years in the past. i like it.i could not in any respect go back to cleansing burners back. The ceramic accurate is really common to guard and the nice and cozy temperature source heats up lots speedier and extra even than burners. i ought to fairly advise buying one. verify round and evaluate expenses.I were given mine at Lowe's.
- Q:Ive heard that metal braces/ gold braces work faster than the ceramic clear ones. IS this true? Does anyone know if you can put colours on the gold metal braces? Also does anyone know of any other types of braces? (P.s I know about invisiline)
- Nothing other than the fabric they are made from and colors they come in.
