ISINGENISO

DonSpray504 yi spray Ukuhlanganiswa polyols, bevuthela inxusa 245fa endaweni HCFC-141B, idityaniswe isocyanate ukuya ugwebu imveliso leyo eye Ukuzimisela, zezi zilandelayo:

1) ifayini ukufana iiseli

2) conductivity thermal ephantsi

3) ukumelana nomlilo ogqibeleleyo

4) emihle ukuwutha lobushushu uzinzo ntathu.

Usebenza kuzo zonke iintlobo yokugquma zobunjineli thermal esebenzisa ubuchwepheshe, ezifana namagumbi abandayo, neembiza, imibhobho emikhulu-isikali kunye nokwakhiwa metope njl
