Gazu' masii

Recommended Posts

Am zis sa nu fac necro la un thread de cativa ani si mai bine intreb aici.(ca nu s-a ajuns la o concluzie)

Pana la urma a gasit cineva butelii de propan pur in tara asta mizerabila? Eu n-am gasit nicaieri doar un amestec cu butan.

Nu stiu de ce nu prea ii comercializat la noi( e interzis sau ce? sau ca deobicei suntem in urma cu multe).

Multumesc.

Singura combinatie de gaze in care gasesti o concentratie mai mare de propan (in nici un caz pur) este GPL-ul. Exista doua tipri de GPL, de vara si de iarna; diferenta este data de concentratia de propan, iarna fiind mai mare. Celalalt gaz din cate stiu eu este butanul care nu e bun nici in bocanci. Nu am incercat sa bag asa ceva in pistol, doar mi-am expus parerea, unde se ''gaseste'' propan la discretie. Daca descoperi cum sa extragi propanul din GPL vei juca cel mai ieftin airsoft, probabil

Any thoughts?

La pret e cam cat o "doza" normala de GreenGas. Dar 750ml propan tin mai multe focuri decat 750ml GG? Si ar merge sa pui un propane-adaptor la asa ceva?

Asta parca mai seamana cu ce vedem pe iutub.

Ala de pe e-camp l-am vazut si eu , am sunat la ei , si mi-au zis ca nu e in stoc, desi pe site aparea cum ca ar fi . Asta era anul trecut prin August.

cu GPL am incercat si eu ....no work

in schimb am gasit propat dar trebuie sa faci contract cu ei te obliga sa cumperi 3-4 butelii de 10 kg pe luna

si e acizat tare......

plus garantie pe butelii

daca faci un calcul nu prea iesi

cred ca o sa incerc asta

ce am gasit pe net despre MAPP GAS:

 

1 - I bought a bottle of Benz-o-matic propylene (MAPP) gas to test. It was around $9 for a can the same size as the Coleman propane cans, which are <$4. I can confirm that it does raise the velocity substantially, and that the cool down effect is substantially smaller.

 

I tested with 2 mags, one with propane and one with propylene, a couple of different ways. I don't have a chrono handy, so I did the PMC to get a range. I tested using my TM P226 with .2g bios and with .25g bios. The temp outside tonight was in the low 70s, and I let both mags warm for 10 minutes prior to each test, and they felt room temp to the touch.

 

On the PMC, propane puts it right around 290fps, which is confirmed by prior chrono results with that gun. The propylene put it at 340fps+, and I'd guess based on the feel of it that it was right around 350fps.

 

The kick with propylene was noticeably harder, enough that I think using it full time when it's >70F might cause wear that propane normally would not. Unless your gun is designed for CO2, propylene seems like it would damage the parts that take impact during a cycle. Personally, I wouldn't use it when the temps are above 60F.

 

The cool down, or lack thereof, was interesting. Normally when I rapid fire a full mag the magazine is cold (not just cool) to the touch, and the pressure drops noticeably toward the end of the mag. With propylene, there was no noticeable drop in pressure, and the mag was barely cool to the touch.

 

My thought, after trying it, is that during winter when gas guns are problematic, using propylene might be a good way to be able to use your pistol effectively. Between the lack of significant cool down and the higher pressure, performance should approximate that of propane during >70F weather. Using it when it's warmer, however, is not advisable.

 

We are supposed to get a few nights in the 40's this week. I'll try these tests again when it's cold outside and let you know how it performs.

2 - Propylene/propene/MAPP gas: Proplyene is an organic compound that is commonly used as a welding gas. Its chemical makeup is C3H6. It is more powerful than green gas but less powerful than red gas. It does not like o rings and seals so it is not recommended to use. Upon further research it seems that its use is safe in airsoft guns. It is commonly used in the UK because it is easier to access than propane in small tanks. It also provides better performance there due to the cold climate. Magazines and guns should be reinforced before using. A propane style adapter and silicone oil are necessary in order to use.

 

3 - As stated, it does work in colder temperatures much better than propane. Significantly less cool down. If my stock WE M4 can handle it then I'd imagine your KJ would work without issue. One thing to note is that if you dislike the smell of propane, your going to hate MAPP, it's pretty smelly.

intrebare: avand in vedere diferenta de presiune, care inteleg ca exista intre propan si ce folosim in mod obisnuit in GBB-uri, stie careva daca propanul afecteaza dramatic incarcatoarele (garnituri etc.)?

nu stiu exact cat ar putea tine un astfel de cartus de propan:

http://www.e-camp.ro/arzator-cartus/1065-cartus-propan-coleman-m1110.html

dar tinand cont ca un tub de Red Gas te costa 120 lei, cu siguranta iti poti recupera investitia in adaptor si banii pe uleiul siliconic destul de repede.

ce ma intriga pe mine este diferenta enorma de pret. sunt constient ca aici intra tot ce inseamna transport, taxe etc...dar chiar de 5 ori mai mult?

chiar si in aceste conditii, tot se merita sa cumperi. din ce m-am interesat peste mari si tari, un tub de propan are de 2 ori mai mult gas ca un tub de green gas. si tinand cont ca am gasit un magazin care vinde chiar aici in Bucuresti, deja am eliminat si costurile de transport la o eventuala comanda pe net.

magazinul este asta si are sediul undeva pe Antiaeriana:

cu cine am vorbit eu, foloseste gazul de la Coleman si dupa cum ati vazut, la ei e doar 4$. dar si cel de la Worthington este bun pentru ca tot propan pur e. nu mai ai nevoie decat de adaptor si ulei siliconic.

o alta recomandare pe care mi-a facut-o este aceea ca trebuie avut grija cand este folosit adaptorul cu varf metalic pentru ca uzeaza valva de umplere.
