Semumwe wevatengesi vemakemikari makuru muPurovhinzi yeShandong, China, tave tiri mberi kwekupa zvigadzirwa zvemakemikari emhando yepamusoro kubva muna 2000. Kunyanya kwedu kugovera zvinhu zvemakemikari zvakasvibiswa uye zvakakosha zvepakati zvakatibvumira kugovera kune zvakasiyana-siyana zvemaindasitiri. Pakati pemakemikari akakosha atinopa Methylene Chloride, Propylene Glycol (PG), uye Dimethylformamide (DMF). Aya makomponi anoita basa rakakosha mumagadzirirwo akasiyana ekugadzira, achiita kuti ave akakosha kune vatengi vedu.
Methylene Chloride, inozivikanwa nokuda kwekunyungudutsa kwayo, inoshandiswa zvakanyanya mukubvisa pendi, kubvisa, uye seyamuro yekugadzirisa mukugadzirwa kwemishonga. Kubudirira kwayo mukunyungudutsa zvinhu zvakasiyana-siyana kunoita kuti ive sarudzo inosarudzika mumashandisirwo mazhinji emaindasitiri. Nekune rimwe divi, Propylene Glycol (PG) isanganiswa inogoneka inoshanda seyakanyorovesa, inonyungudutsa, uye inochengetedza muchikafu, zvekuzora, uye mishonga. Yayo isiri-chepfu hunhu uye kugona kuchengetedza mwando inoita kuti ive chinhu chakakosha mukugadzira kwakawanda. Dimethylformamide (DMF), polar aprotic solvent, yakakosha mukugadzirwa kwefibers, mapurasitiki, nemishonga, ichipa kunyungudika kwakanyanya kweakasiyana siyana organic uye inorganic komisheni.
Tine yedu yekuchengetera zvinhu uye yakura yekugovera cheni, isu tinoona kuti vatengi vedu vanogashira izvi makemikari zvigadzirwa nemitengo yemakwikwi pasina kukanganisa pamhando. Kuzvipira kwedu kune kugona uye kugutsikana kwevatengi kwakatisimbisa semubatsiri akavimbika muindasitiri yemakemikari. Sezvo isu tichienderera mberi nekuwedzera zvipiriso zvedu, isu tinoramba takazvipira kutsigira vatengi vedu nemidziyo yavanoda kuti vagadzirise uye kubudirira mumisika yavo. Kunyangwe iwe uchida Methylene Chloride, PG, DMF, kana mamwe makemikari epakati, isu tiri pano kuti tisangane nezvido zvako nemazvo uye nemazvo.
