Ester puag roj rau tub yees compressors
Ester puag roj rau tub yees compressors
Neopentyl saturated polyols yog cov roj hauv paus uas yaj nrog HFC tub yees.
Lawv tsim nyog siv rau hauv reciprocating, gyro-hom thiab dov tub yees compressors ntawm R-134A, R-407C thiab R-410A.
Nws muaj cov thermal stability zoo, hydrolysis stability, tsis tshua muaj evaporation tus nqi thiab qis coke nyiam, thiab lwm yam.
Cov qauv tsim sib txawv ua tau raws li qhov yuav tsum tau ua kom haum miscibility ntawm ntau cov tub yees.
