Gwiritsani ntchito

Izi mankhwala osati ntchito kaphatikizidwe organic, komanso ankagwiritsa ntchito monga mapadi acetate filimu, mapadi triacetate kupota, petroleum dewaxing, aerosol ndi mankhwala, mavitamini, steroids kupanga zosungunulira, ndi zitsulo pamwamba utoto wosanjikiza wosanjikiza kuyeretsa degreasing ndi kuvula wothandizila. . Kuphatikiza apo, imagwiritsidwanso ntchito ngati fumigation yambewu ndi firiji ya mafiriji otsika kwambiri komanso ma air conditioners. Amagwiritsidwa ntchito ngati chothandizira kuwomba popanga thovu la Polyether urethane komanso ngati chowombera chotulutsa thovu la polysulfone.

Chitetezo

kawopsedwe ndi kakang'ono kwambiri, ndipo chikumbumtima ndi mofulumira pambuyo poyizoni, choncho angagwiritsidwe ntchito ngati mankhwala ochititsa dzanzi. Zokwiyitsa pakhungu ndi mucous nembanemba. Makoswe akuluakulu amkamwa ld501.6ml/kg. Pazipita chololeka ndende mu mpweya ndi 500 × 10-6. Opaleshoniyo iyenera kuvala chigoba cha gasi, chomwe chikapezeka pambuyo poyizoni kuchokera pamalowo, chithandizo chazidziwitso ndi ng'oma yachitsulo chotsekedwa, 250kg pa mbiya, tanki ya sitima yapamtunda, galimoto imatha kunyamulidwa. Ziyenera kusungidwa mu kuzizira mdima youma, bwino podutsa mpweya malo, kulabadira chinyezi.
