Koresha

Iki gicuruzwa ntigikoreshwa gusa muri synthesis organique, ariko kandi gikoreshwa cyane nka firime ya selulose acetate, kuzunguza selile triacetate, kuzunguruka peteroli, aerosol na antibiotike, vitamine, steroyide mugukora ibishishwa, hamwe nicyuma cyo hejuru cyicyuma gisukura kwangirika no kwambura ibikoresho. . Byongeye kandi, ikoreshwa no muguhunika ingano no gukonjesha firigo zikonjesha nkeya hamwe na konderasi. Ikoreshwa nkibikoresho bifasha muguhingura ifuro ya Polyether urethane kandi nkibikoresho byo guhumeka ifuro rya polysulfone.

Umutekano

uburozi ni buto cyane, kandi ubwenge burihuta nyuma yuburozi, bityo burashobora gukoreshwa nka anesthetic. Kurakara kuruhu no mu mucyo. Imbeba zikuze zikuze umunwa ld501.6ml / kg. Umubare ntarengwa wemewe mu kirere ni 500 × 10-6. Igikorwa kigomba kwambara mask ya gaze, iboneka ako kanya nyuma yuburozi bwaho, kuvura ibimenyetso hamwe ningoma ya fer ya feri yafunzwe, 250 kg kuri barrale, imodoka ya gari ya moshi, imodoka irashobora gutwarwa. Ugomba kubikwa ahantu hakonje hijimye, hahumeka neza, witondere ubushuhe.
