Ko te whakarunga o te mekameka ahumahi nitrocellulose ko te nuinga o te miro para, te waikawa nitric me te waipiro, a ko nga waahanga tono matua o raro ko te whakatairanga, te peita nitro, te waituhi, nga hua celluloid, te whakapiri, te hinu hiako, te whao me etahi atu mara.
Ko nga mea matua o te nitrcellulose ko te miro para, te waikawa nitric, te waipiro, me etahi atu.Xinjiang, Hebei, Shandong, Jiangsu me etahi atu waahi kei te hanga tonu i nga kaupapa miro parakore, a kua piki haere te kaha o te ahumahi, e whakarato ana i nga rawa rawaka mo te hanga o te nitrocellulose.
Ko te hanga miro parakore a Haina i te tau 2020 ka tata ki te 439,000 taranata.Ko te hanga o te waikawa nitric he 2.05 miriona taranata, ko te hanga o te waipiro fermented he 9.243 miriona rita.
Ko te nitrocellulose Haina te nuinga o te kaweake ki United States me Vietnam, ko nga whenua e rua neke atu i te haurua o te kawe nitrocellulose o roto. Ko nga raraunga e whakaatu ana, i te tau 2022, ko te kaweake nitrocellulose a Haina ki Amerika me Vietnam he 6100 toni me te 5900 toni, e 25.5 tone. % me 24.8% o te kawe nitrocellulose motu. France, Saudi Arabia, Malaysia are accounting for 8.3%, 5.2% and 4.1%.
Mo te whakataurite ki te kawemai me te kaweake o te nitrocellulose, he nui ake te tauine kawemai nitrocellulose o Haina i te tauine kawemai.Ko te kawemai o te nitrocellulose he tata ki te rau taranata, engari ko te kaweake he 20,000 tone.Otirā, i te tau 2021, ka piki ake te hiahia o te ao me te kaweake i te tino nui, ka eke ki te tihi 28,600 tana i te tau tata nei.Heoi, na te COVID-19 i te tau 2022, ka heke te tono ki te 23,900 tone. Mo te kawemai, ko te kawemai o te nitrocellulose he 186.54 tone i te tau 2021 me te 80.77 tone i te tau 2022.
E ai ki te tatauranga, mai i nga hauwhiti tuatahi e toru o te tau 2021, ko te nui o te nitrocellulose kawemai a Haina ko te 554,300 taara, he 22,25% te pikinga, ko te moni kaweake he 47,129 miriona taara, he 53,42%.
