- Kala fogaanshaha rinjiyeynta:
Heerkulka substrate-ka ℃ 5-10 15-20 25-30
Mudada gaaban ee h48 24 12
Muddada daaweynta waa in aysan ka badnayn 7 maalmood. - Heerkulka substrate-ka waa inuu ka sarreeyaa dhibicda dharabka oo ka badan 3 ℃, marka heerkulka substrate-ku uu ka hooseeyo 5 ℃, filimka rinjiga lama bogsiin karo, waa in aan la dhisin.
Dhismaha rinjiyeynta
- Ka dib marka la furo foostada qaybta A, waa in si fiican loo walaaqo, ka dibna ku shub qaybta B qaybta A iyadoo la walaaqayo iyadoo la raacayo shuruudaha saamiga, si fiican u walaaq, u daa inay istaagto oo kariso 30 daqiiqo, ka dibna ku dar qadar khafiif ah oo ku habboon oo u hagaaji si waafaqsan isku-dhafka dhismaha.
- Diluent: diluent gaar ah oo loogu talagalay taxanaha polyurethane.
- Buufin aan hawo lahayn: Tirada milmidu waa 0-5% (marka loo eego saamiga miisaanka rinjiga), cabbirka afka waa 0.4mm-0.5mm, cadaadiska buufintu waa 20MPa-25MPa (200kg/cm²-250kg/cm²).
- Buufinta hawada: Tirada milmidu waa 10-15% (marka loo eego saamiga miisaanka rinjiga), cabbirka afka waa 1.5mm-2.0mm, cadaadiska buufintu waa 0.3MPa-0.4MPa (3kg/cm²-4kg/cm²).
