Ipeyinti yePolyurethane yamanzi
I-trapezium ekhethekileyo evela kumazwe angaphandle, isayensi yeekhemikhali kazwelonke, amanzi adibeneyo, i-additives esekelwe emanzini kunye ne-filler yokusingqongileyo kunye nezinye izinto, aziqukethe i-benzene, intsapho, i-benzene ye-second-grade kunye nezinye i-solvents eziphilayo. usebenzisa i-aliphatic polyurethane resin esekwe emanzini njengesiseko sefilim, i-HDI njenge-ejenti yokunyanga, ukongeza izizalisi ezinobume bendalo kunye nezincedisi ezisebenzayo. Ifilimu epheleleyo, iglosi ephezulu, umbala oqaqambileyo. Ukubambelela kakuhle, ubunzima obuphezulu, ukuchasana kwemozulu okugqwesileyo.
Indawo yosetyenziso
Ifanelekile kwiimfuno zomgangatho ophezulu, iimfuno zokumelana nemozulu ephezulu yepeyinti yokupenda. Isetyenziswa ikakhulu kumhombiso womphezulu wamacandelo esinyithi afana ne-wind power tower barrel, izixhobo zoomatshini, oomatshini bokwakha, umbhobho we-oyile yepetrochemical, njl.
Unyango lomphezulu
1. Umphezulu kufuneka ucoceke kwaye wome, kwaye unyango olungaphezulu lwe-substrate kufuneka luhlangabezane neemfuno.
2. Izixhobo ezisetyenziswa ekwakhiweni kufuneka zome kwaye zicoceke. 3.
3. kunqatshelwe ukudibanisa ne-asidi kunye ne-alkali ngexesha lenkqubo yokulungisa ipeyinti kunye nokugubungela.
4. ixesha lokupeyinta kufuneka lilawulwe ngokungqongqo, xa iqondo lokushisa liyi-25'C, ixesha lokupeyinta aliyi kuba ngaphantsi kweeyure ezili-12.
5. Awukwazi ukupeyinta ubukhulu, ifilimu ayinakudlula i-40μm okanye iya kuba neqamza.
6. Ukwakhiwa kunye nokumisa kunye nokunyanga ngexesha lokufuma kwesalamane akukho mkhulu kune-75%, ubushushu abukwazi ukuba ngaphantsi kwe-0 ℃ C, ngaphandle koko ifilimu ayinakunyangwa ngokupheleleyo impembelelo.
