I-China Donpipe 301 inhlanganisela yesisekelo samanzi i-polyols yokwahlukanisa amapayipi Umkhiqizi Nomhlinzeki

I-Donpipe 301 ehlanganisa isisekelo samanzi se-polyols yokufakwa kwamapayipi

Incazelo emfushane:

Lo mkhiqizo uwuhlobo lokuhlanganisa ama-polyols namanzi njenge-ejenti egwebulile, ecwaningwa ngokukhethekile ukuze kutholakale i-PUF eqinile ukuze kukhiqizwe amapayipi okufaka ukushisa okushisayo. Isetshenziswa kabanzi kumapayipi esitimu, amapayipi egesi emvelo ane-liquefied, amapayipi kawoyela neminye imikhakha.

IISINGENISO

(1) ukugeleza okuhle, ngokulawula ifomula ukuze ivumelane namadayamitha amapayipi ahlukene.

(2) ukusebenza okuphezulu kokumelana nokushisa, ukuma isikhathi eside ku-150 ℃

(3) okuhle kakhulu izinga lokushisa eliphansi ukuzinza dimensional
