Qaybta sare ee silsiladda warshadaha nitrocellulose ayaa ah inta badan suuf la safeeyey, nitric acid iyo alkohol, iyo meelaha hoose ee laga codsado waa kuwa wax soo saara, rinjiga nitro, khadyada, alaabada celluloid, xabagta, saliida maqaarka, cidiyaha cidiyaha iyo meelo kale.
Qalabka ugu muhiimsan ee nitrcellulose waa suuf la safeeyey, nitric acid, khamriga, iwm. Horumarinta suufka la safeeyey ee Shiinaha ayaa soo maray in ka badan nus qarni.Xinjiang, Hebei, Shandong, Jiangsu iyo meelo kale waxay sii wadaan inay dhisaan mashaariicda suufka ah ee la safeeyey, awoodda warshadaha ayaa si tartiib tartiib ah u ballaarisay, siinta alaabta ceeriin ee ku filan soo saarista nitrocellulose.
Wax soo saarka suufka la safeeyey ee Shiinaha 2020 wuxuu noqonayaa ilaa 439,000 oo tan.Wax-soo-saarka nitric acid wuxuu ahaa 2.05 milyan oo tan, iyo wax-soo-saarka aalkolada khamiirsan waxay ahayd 9.243 milyan litir.
Nitrocellulose-ka Shiinaha ayaa inta badan loo dhoofiyaa Maraykanka iyo Vietnam, labada waddan ayaa ka badan kala badh dhoofinta nitrocellulose gudaha. % iyo 24.8% dhoofinta nitrocellulose qaranka.France, Saudi Arabia, Malaysia waxay ku xisaabtamayaan 8.3%, 5.2% iyo 4.1% siday u kala horreeyaan.
Marka la eego isbarbardhigga soo dejinta iyo dhoofinta nitrocellulose, miisaanka dhoofinta nitrocellulose ee Shiinaha aad ayuu uga weyn yahay cabbirka soo dejinta.Soo dejinta nitrocellulose waa ilaa boqollaal tan, laakiin dhoofintu waa ilaa 20,000 oo tan.Gaar ahaan, 2021, baahida caalamiga ah ayaa kor u kacday iyo dhoofinta ayaa si aad ah u korodhay, taasoo gaartay 28,600 tan ugu sarreysa sannadkii dhawaa.Si kastaba ha noqotee, COVID-19 dartiis ee 2022, baahida ayaa hoos ugu dhacday 23,900 tan. Dhanka soo dejinta, soo dejinta nitrocellulose waxay ahayd 186.54 tan 2021 iyo 80.77 tan 2022.
Marka loo eego tirakoobka, illaa saddexdii rubuc ee ugu horreeya 2021, lacagta nitrocellulose ee Shiinaha ee soo dejinta waxay ahayd 554,300 US dollars, korodhka 22.25%, iyo qaddarka dhoofinta ayaa ahayd 47.129 milyan doolarka Mareykanka ah, koror ah 53.42%.
