Dichlorodifluoromethane tuaj yeem pom qhov twg thiab siv nws li cas? Dichlorodifluoromethane yog siv los ua cov roj refrigerant hauv tub yees thiab cua txias. Dichlorodifluoromethane kuj tseem siv tau rau hauv cov tshuaj tsuag aerosol, hauv cov yas, thiab ua ib qho kev pab hauv kev tshawb xyuas cov xau.

Dichlorodifluoromethane ua li cas?

YUAV UA LI CAS. Dichlorodifluoromethane yog tsim los ntawm reacting carbon tetrachloride (CCl 4) nrog hydrogen fluoride gas (H2 F 2) nyob rau hauv lub xub ntiag ntawm lub catalyst , feem ntau yog antimony pentafluoride (SbF5).

Puas yog dichlorodifluoromethane phem rau ib puag ncig?

Qhov cuam tshuam rau ib puag ncig los ntawm DCDFM yog feem ntau yuav tsis ncaj ncees, dhau los ntawm kev puas tsuaj rau txheej txheej ozone. Ozone txheej depletion ua rau kom muaj ultraviolet (UV) hluav taws xob, uas tuaj yeem cuam tshuam cov txheej txheem kev loj hlob hauv cov nroj tsuag, suav nrog cov nroj tsuag hauv dej thiab algae.

Yog CF2Cl2 soluble hauv dej?

Cov khoom ntawm CF2Cl2

Nws muaj qhov taw tes qis heev -157.7 ° C thiab kub taw tes -29.8 ° C thiab nws yog soluble hauv cov kuab tshuaj polar xws li dej, cawv, benzene, acetic acid, thiab lwm yam.

Puas yog refrigerant gas lossis kua?

Cov tub yees, cov tshuaj sib xyaw uas hloov tau yooj yim los ntawm cov kua rau roj. Thaum cov tub yees raug thawb rau hauv lub compressor, nws yog cov pa roj tsawg.
