Heerkulka kaydinta: -10 ~ 40 ℃
Heerkulka dhismaha:5～40℃
Muddada tijaabada: 6h
Habka dhismaha: cadayashada, buufinta hawada, duubista ayaa la isticmaali karaa.
Inta u dhaxaysa rinjiyeynta:
Heerkulka substrate-ka ℃ 5-10 15-20 25-30
Muddada gaaban h48, 24, 12
Muddada dheer oo aan ka badnayn 7 maalmood.
Heerkulka substrate-ku waa inuu ka sarreeyaa barta sayaxa ee ka badan 3 ℃, marka heerkulka substrate-ku uu ka hooseeyo 5 ℃, filimka rinjiga lama daawayn, waana inaan la dhisin.

Ka dib marka la furo foostada qaybta A, waa in si fiican loo walaaqaa, ka dibna kooxda B ku shub qaybta A ee hoos yimaada walaaqaya sida waafaqsan shuruudaha saamiga, si fiican u walaaq oo u dhaaf inay qaan gaadheyso 30mins, ka dibna ku dar qadar ku habboon oo khafiif ah oo ku hagaaji viscosity dhismaha.
Diluent: dareere gaar ah oo loogu talagalay taxanaha polyurethane.
Ku buufinta bilaa hawada: Qadarka qasitaanku waa 0-5% (miisaanka rinjiga), caliber caliber waa 0.4mm-0.5mm, buufinta cadaadiska waa 20MPa-25MPa (200kg/cm²-250kg/cm²).
Buufinta hawada: Qadarka qasitaanku waa 10-15% (miisaanka rinjiga), caliber caliber waa 1.5mm-2.0mm, buufinta cadaadiska waa 0.3MPa-0.4MPa (3kg/cm²-4kg/cm²).
Dahaarka Roller: Qadarka milanka waa 5-10% (marka la eego saamiga miisaanka rinjiga).

Xilliga heerkulka sare ee dhismaha, buufin si sahlan loo qallajin karo, si looga fogaado buufinta qalalan waxaa lagu hagaajin karaa khafiif ah ilaa aan qallajin.
Alaabtan waa in ay adeegsadaan hawl-wadeennada rinjiyeynta xirfadleyda ah si waafaqsan tilmaamaha xirmada alaabta ama buug-gacmeedkan.
Dhammaan dahaarka iyo isticmaalka alaabtan waa in loo fuliyaa si waafaqsan dhammaan xeerarka iyo heerarka caafimaadka, badbaadada iyo deegaanka.
Haddii aad shaki ka qabtid in alaabtan la isticmaalo, fadlan la xiriir waaxdayada adeegga farsamada wixii faahfaahin ah.
