dear college … yes i use pe as a binder an ldpe sheets for faster extruding .. nearly everything you can use for extruding at about 200 celsius, except Pet … see you wolfi
I’ve had too many bad experiences with extruding pe and ps … that’s why I am trying to develop simple ways of making beams. .. but always looking for getting more information and ideas from other colleagues. What do you think ?https://www.youtube.com/watch?v=gsnsitKldyU
thanks for your answer … i will put on a sponge full of oil which is pushed forward by the molten mass …
thanks for your answer .. i think it was too hot as the product was black, what means carbon …
hallo friend .. i am not sure if my contribution is helpful … i bought a raclette with a flat surface for 30 dollar … and pressed styrofoam cups on it … they melted but uneven, because i didn’t shred the cups … now i have a shredder and will try to repeat similar process … can we press a plate and push the board sidewards to continue melting the next connected part and so on …
… between two aluminium sheets, heated by gas one can melt a larger amount of eps to make sticks and maybe it’s possible to make them wider in order to get boards … see our video … wish you success …
hi kahlid .. i just read your inbox .. I’m not an expert on plastic but i used to teach chemistry … you should sort plastic into some main categories …
…. long carbohydrogen chains like ldpe,hdpe and even pp shredder … not above 200 Celsius and not containing circular structures like like ps
once you have more experience, sort out also pp ..
… carbohydrogen structure that contain rings like ps and heat them as hot as around 230 celcius… don’t mix them with pe or pp as they won’t connect
… don’t add pvc or other compounds containing chlorine … reaction could create dioxines and other kinds of poison ..
if you make sticks and boards it’s alright to have contamination in them as compact material doesn’t enter the food chain or damage animals … decades later people may bury it somehow without any harm in concrete walls etc.
… go on in your search and try no to breathe gases … i hope this is useful for you … wolfi
hi khalid … how do you extrude fused plastic … any videos ?
