Donpipe 301 amanzi isiseko lwemenu polyols for umbhobho elana
I NTRODUCTION
Le mveliso i uhlobo lwemenu polyols ngamanzi njenge-arhente ugwebu, esixhotyiswe ngokukodwa uphando ukuze PUF ngqongqo ukuvelisa imibhobho usambathisa thermal. Isetyenziswa ngokubanzi kwimibhobho umphunga, irhasi yohlobo lwepetroliyam imibhobho, imibhobho oyile kunye nezinye iinkalo esebenzayo. Ezona mpawu zezi zilandelayo:
(1) elungileyo flowability, ngokulawula ifomula ukuba ivumelane ngobubanzi umbhobho ezahlukeneyo.
(2) ukusebenza eliphezulu lobushushu-ukuxhathisa, elide emi 150 ℃
(3) Iqondo lobushushu eliphantsi uzinzo kakhulu mbini
