I-Donpipe 301 ehlanganisa isisekelo samanzi se-polyols yokufakwa kwamapayipi
IISINGENISO
Lo mkhiqizo uwuhlobo lokuhlanganisa ama-polyols namanzi njenge-ejenti egwebuzelayo, ecutshungulwa ngokukhethekile i-PUF eqinile ukuze kukhiqizwe amapayipi okushisa ashisayo.Isetshenziswa kabanzi kumapayipi esitimu, amapayipi egesi emvelo ane-liquefied, amapayipi kawoyela neminye imikhakha.Izici zimi kanje:
(1) ukugeleza okuhle, ngokulawula ifomula ukuze ivumelane nobubanzi obuhlukene bamapayipi.
(2) ukusebenza okuphezulu kokumelana nokushisa, ukuma isikhathi eside ku-150 ℃
(3) okuhle kakhulu izinga lokushisa eliphansi ukuzinza dimensional
