JOPETES Posted June 2, 2014 Posted June 2, 2014 Hola a todos. Si alguien tiene algun problema con las formulas del pdf o con el cebado de estrellas puedo ayudar, será un placer. tambien puede ponerse en contacto conmigo a mi email jopetes@terra.com.
Mumbles Posted June 3, 2014 Posted June 3, 2014 While I do speak spanish, and appreciate your offer to the members here. This is an english only forum.
Maserface Posted June 3, 2014 Posted June 3, 2014 This is the guy that posted a PDF of formulas some time ago, they have all been deciphered on fireworking. http://www.amateurpyro.com/forums/topic/6544-formulas-priming-and-technical-pyrotechnics/He spoke betttter english then
stibium Posted June 3, 2014 Posted June 3, 2014 JOPETES, in your formula of monocapa prime, you use black iron oxide,but could be replaced by red iron oxide, which is a chemical easier to acquire?
Bobosan Posted June 4, 2014 Posted June 4, 2014 Black and red both work fine (great actually).+1 I've also used the red and it does work.
BurritoBandito Posted June 4, 2014 Posted June 4, 2014 (edited) For the non Spanish speakers here (like myself) here is a translation of the original post: "Hello everyone. If anyone has a problem with the formulas of the pdf or Prime star I can help, it will be a pleasure. also please contact me to my email jopetes@terra.com." Edit: @Jopetes: La traducción estuvo bien. (Your translation was fine.) Edited June 4, 2014 by BurritoBandito
JOPETES Posted June 4, 2014 Author Posted June 4, 2014 Stibium,You can also use red iron oxide, it works very similar.you can use in place of its silicon. These components have very similar functions, is to train a little slag to facilitate ignition of the star. much of the heat is provided by KClO4 and magnalium. sulfur and especially light charcoal (willow, poplar or poplar, maple, balsa) facilitate the ignition of the monolayer at high speed. You can replace the magnalium by German quality black aluminum 2 micron and add to formula 1 % boric acid. with black aluminum works a little better that facilitates ignition of the monolayer at high speed because the German black aluminum is very thin. I apologize for the translations in English , I used the google translator.
TYRONEEZEKIEL Posted July 11, 2014 Posted July 11, 2014 Your translations are fine. Google does a good job!
eb11 Posted August 13, 2014 Posted August 13, 2014 I am trying to figure out these 2 words looked all over and cant find the English term for them any help would be appreciated. they are empavonado and bluing and also capa thank you
Bobosan Posted August 13, 2014 Posted August 13, 2014 If I can find these online, anyone can. capa means layer, cover or coat. Empavonado is blue. capa cape; layer DictionaryVideocapa feminine noun1. cloak, cape (manto) andar de capa caída (informal) to be in a bad way; (persona) to be struggling (negocio)defender algo a capa y espada to defend something tooth and nail hacer de su capa un sayo to do as one pleases 2. coat (baño) (de barniz, pintura) ; coating (de chocolate) 3. layer (estrato) ; stratum, layer (geology) capa atmosférica atmosphere una capa de hielo a film of ice capa de ozono ozone layer capa terrestre Earth's surface empavonar DictionaryConjugationempavonartransitive verb1 (Técnica) [+acero] to blue2 (Latinoamérica) (Mecánica) to grease; cover with grease
eb11 Posted August 13, 2014 Posted August 13, 2014 When I did the Google translate it did say blue but I was not sure for how long the Spanish word was. So my next question is it the color blue or does it meen something else
Shadowcat1969 Posted August 13, 2014 Posted August 13, 2014 In this document Empavonado means coat or layer. So he is talking about first layer of prime, second layer of prime. Capa means layer or coating. So monocapa means Single Layer. That particular prime is a single layer prime and does not need either a transition layer of hot prime under it OR a layer of rough powder or igniter on top of it.
SchlingelPyro Posted August 25, 2014 Posted August 25, 2014 Hola jopes Thank you for sharing the .pdf great work.Have you a chart how many apertura you use for different shell size?Thank you for the information SPyro
kaffo Posted August 27, 2014 Posted August 27, 2014 Thank you very much Jopetes I´ve heard a lot of positive comments regarding your formulas, can´t wait to try them out!
dangerousamateur Posted August 30, 2014 Posted August 30, 2014 That particular prime is a single layer prime and does not need either a transition layer of hot prime under it OR a layer of rough powder or igniter on top of it. That's how i understand this too. But does it really function that way?A little unmilled BP on top wont hurt anyway, but would this prime really light without it?
Bobosan Posted August 30, 2014 Posted August 30, 2014 That's how i understand this too. But does it really function that way?A little unmilled BP on top wont hurt anyway, but would this prime really light without it? It does. Had some blue parlon stars using monocapa only and could see the prime burning as they left the star gun. Problem I had was not applying a thick enough coat of the monocapa and some stars tested blind. After rolling a thicker layer, no problems getting them to ignite.
dangerousamateur Posted August 31, 2014 Posted August 31, 2014 Interesting. And how thick does the prime need to be?I find this prime to burn extremely slowly, is that normal? At least when compared with other perchlorate primes. Wont that be blown out when broken hard? Slow burning mixes often do that.
Bobosan Posted August 31, 2014 Posted August 31, 2014 I push the star gun pretty hard while testing these stars and like I mentioned, could actually see the thinner layer of monocapa burn around the star as it rose in the air. So yes, I would say a slower burn but much hotter burn. I've been putting 1/32 to 1/16 layer on the parlon blues. Pretty thick but it works.
mabuse00 Posted November 19, 2021 Posted November 19, 2021 Sorry if this has been covered before: I want to make a few blue bengal fires and tend to use Azul 1 or Azul 2. How do these two differ in burning behaviour?If phenolic resin is at hand - would these stars rather benefit from it or not?
