iye main mbishi zvinhu zvinodiwa pakugadzirwa kwecellulose etherzvinosanganisira donje rakanatswa (kana pulp yehuni) uye zvimwe zvinonyungudutsa kemikari, sepropylene oxide, methyl chloride, liquid caustic soda, caustic soda, ethylene oxide, toluene nezvimwe zvinhu zvinobatsira. Iwo ekumusoro indasitiri mabhizinesi eindastiri iyi anosanganisira yakanatswa donje, huni pulp kugadzira mabhizinesi uye mamwe mabhizinesi emakemikari. Kuchinja-chinja kwemitengo yezvinhu zvadudzwa pamusoro apa kuchave nemadhigirii akasiyana ekukanganisa pamutengo wekugadzira uye mutengo wekutengesa we cellulose ether.
Mutengo wekotoni yakanatswa yakanyanya. Kutora zvinhu zvekuvaka giredhi cellulose ether semuenzaniso, panguva yekubika, mutengo wekotoni yakanatswa yakaverengera 31.74%, 28.50%, 26.59% uye 26.90% yemutengo wekutengesa wekuvaka giredhi cellulose ether zvichiteerana. Kuchinja kwemutengo wekotoni yakanatswa kuchakanganisa mutengo wekugadzira cellulose ether. Iyo huru yakasvibirira yekugadzirwa kwekotoni yakanatswa ikotoni linters. Cotton linters ndeimwe yezvigadzirwa mukugadzira donje, inonyanya kushandiswa kugadzira donje pulp, rakanatswa donje, nitrocellulose uye zvimwe zvigadzirwa. Iko kukosha kwekushandisa uye kushandiswa kwekotoni linters nekotoni zvakasiyana chaizvo, uye mutengo wayo zviri pachena wakaderera pane wekotoni, asi ine kumwe kuwirirana nemutengo wekuchinja kwekotoni. Kuchinja-chinja kwemutengo wekotoni linters kunokanganisa mutengo wekotoni yakanatswa.
Iko kuchinjika kwakanyanya mumutengo wedonje rakacheneswa kuchave neakasiyana madhigirii ekukanganisa pakutonga kwemitengo yekugadzira, mutengo wechigadzirwa uye pundutso yemabhizinesi muindasitiri ino. Kana mutengo wekotoni yakanatswa wakakwira uye mutengo wehuni pulp wakaderera, kuitira kuderedza mutengo, matanda ehuni anogona kushandiswa sechinotsiva uye kuwedzera kwedonje rakanatswa, kunyanya kugadzirwa kwe cellulose ethers ine yakaderera viscosity senge. giredhi remishonga uye chikafucellulose ethers. Zvinoenderana nedata kubva pawebhusaiti yeNational Bureau of Statistics, muna 2013, nzvimbo yekudyara donje munyika yangu yaive mahekita 4.35 miriyoni, uye donje renyika rakabuda raive 6,31 miriyoni matani. Zvinoenderana nenhamba dzakabva kuChina Cellulose Industry Association, muna 2014, kuburitsa kwedonje rakanatswa rakagadzirwa nevagadziri vedonje rakanatswa mudzimba raive matani 332,000, uye kupihwa kwemidziyo yakawanda.
Iyo mikuru yezvigadzirwa zvekugadzira graphite makemikari emidziyo isimbi uye graphite kabhoni. Mutengo wesimbi uye graphite kabhoni unotora chikamu chakakwirira chemutengo wekugadzira wezvigadzirwa zvemakemikari egraphite. Kuchinja kwemitengo yezvinhu izvi mbishi kuchave nekukanganisa pamutengo wekugadzira uye mutengo wekutengesa wezvigadzirwa zvemakemikari emagraphite.
