Ti-single-base propellant yenziwe kuphela i-nitrocellulose (NC), kuyilapho i-double-base propellant ine-nitrocellulose ne-nitroglycerin (NG) njengezingxenye eziyinhloko.
Isithako esisebenzayo se-single-baseizinzipho ezihlanganisiwei-nitrocellulose, eyaziwa nangokuthi i-nitrocellulose noma i-cotton powder. Ingeka-nitrate esters futhi iwumkhiqizo okhiqizwa ukusabela kwe-esterification ye-cellulose ne-nitric acid. Inomjikelezo omude wokukhiqiza futhi inezingxenye ezibalulekile Eziguquguqukayo futhi i-hygroscopicity ingase ibangele izinguquko ezakhiweni ngesikhathi sokugcina.
Lapho umshini wokubethela ohlanganisiwe usetshenziselwa ukwethula, i-nitrocellulose noma i-plastic shell propellant iyaqhuma, futhi ukuqhuma kushayela izipikili ezintweni eziyisisekelo ukuze kuzuzwe.ukuqiniswaizinjongo.
I-nail ehlanganisiwe ephansi kabili iyi-nail ehlanganisiwe ene-plasticizers eqhumayo njenge-nitrocellulose ne-nitroglycerin njengengxenye yamandla eyinhloko. Inezinzuzo ze-hygroscopicity ephansi, ukuzinza okuhle ngokomzimba, ukusebenza okuzinzile, kanye nobubanzi bamandla obulungisekayo. Okwamanje iyatholakala emakethe. Isetshenziswa kabanzi.
Njengohlobo olusha lomkhiqizo wokubopha, isimiso sokusebenza se-double-base-nail ehlanganisiwe ukusebenzisa okukhethekileisibhamu sezinziphoukuthungela i-propellant ku-nail ehlanganisiwe, ukukhulula amandla, futhi ushayele izipikili ezihlukahlukene ngokuqondile ensimbi, ukhonkolo, i-masonry nezinye izinto eziyisisekelo. Lungisa izingxenye ezidinga ukulungiswa unomphela noma okwesikhashana. Izinzipho ezihlanganisiwe zithandwa ngokushesha ngabathengi ngenxa yesisindo sazo esilula, ukufakwa kalula, akukho ukungcola kothuli, nokusebenza okubanzi. Zisetshenziswa kabanzi kumafreyimu ophahleni, amaphaneli okuhlobisa odongeni lwangaphandle, ukufakwa kwesimo somoya nezinye izikhathi.
