DONSPIPE 301 Dej Hauv Paus Rov Ua Polyols rau Pipeline Rwb Thaiv Tsev
DONSPIPE 301 Dej Hauv Paus Rov Ua Polyols rau Pipeline Rwb Thaiv Tsev
INtroduction
Cov khoom no yog ib hom kev sib xyaw ua ke nrog cov dej ua npuas dej, uas yog tshawb fawb rau cov bigid pipes thipes. Nws yog dav siv nyob rau hauv cov kav dej steames, liquefied xwm khiav kav, roj kav thiab lwm thaj teb. Cov yam ntxwv muaj raws li nram no:
(1) zoo heev flowerability, los ntawm kev tswj hwm cov mis kom haum cov kab ntsig sib txawv.
(2) Kub-Kuj Tseem Ceeb, Ntev Sawv Hauv 150 ℃
(3) Qhov ntsuas hluav taws xob zoo tshaj plaws nyob sab ruaj khov
