Maaddooyinka
- Birta cas ee poliurethane (Red polyurethane primer) waxa ay ka kooban tahay xabagta hydroxyl ka kooban, bir oxide cas, faylaha midabka lidka ku ah, wax lagu daro, dareerayaasha, iwm.
Astaamaha
- Hanti antirust heer sare ah.
- adhesion heer sare ah oo lagu daaweeyay birta.
- Daaweyn heerkul hooseeya oo heer sare ah.
- Biyo aad u fiican iyo iska caabbinta daxalka.
- Qalajin degdeg ah iyo iska caabin saliid oo wanaagsan.
Qiyaasaha farsamada (qayb)
- Xaaladda weelka: ma jiraan kuusyo adag ka dib walaaq iyo qas, xaalad labis ah

- Laabashada caabbinta: 1mm (tusmada caadiga ah: GB/T1731-1993)
- Waqtiga qalajinta: qalajinta dusha sare ≤ 1 saac, qallajin adag ≤ 24h (tusmada caadiga ah: GB/T1728-79)
- Iska caabinta saamaynta: 50cm (tusmada caadiga ah: GB/T4893.9-1992)
Adeegsada
- Ku habboon qaab dhismeedka birta, haanta saliidda, haanta saliidda, qalabka kiimikada ka hortagga, qalabka elektiroonigga ah, gaadiidka gaadiidka sida dahaarka priming antirust.
Daaweynta dusha sare
- Ciidda dusha birta ah ilaa heerka Sa2.5, qallafsanaanta dusha sare 30um-75um.
- Qalabka korantada oo hoos u dhigaya heerka St3.
Xidhmada hore ee koorsada
- Si toos ah loogu rinjiyeeyay dusha birta oo tayadeeda ka saarista miridhku gaadhay darajada Sa2.5.
Isbarbardhigga ka dib
- Rinjiga poliurethane, rinjiga polyurethane, jaakad sare ee polyurethane akrilik, jaakadda sare ee fluorocarbon.
Xuduudaha dhismaha
- Dhumucda filimka lagu taliyay: 60-80um
- Qiyaasta aragtida: qiyaastii 115g/m² (ku salaysan 35um filim qalalan, marka laga reebo khasaaraha).
- Tirada rinjiyeynta la soo jeediyay: 2 ~ 3 baasay
- Heerkulka kaydinta: -10 ~ 40 ℃
- Heerkulka dhismaha: 5 ~ 40 ℃
- Muddada tijaabada: 6h
- Habka dhismaha: cadayashada, buufinta hawada, duubiddu waxay noqon kartaa.
- 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 uu ka hooseeyo 5 ℃, filimka rinjiga lama daawayn, waa in aan la dhisin.
Dhismaha rinjiyeynta
- Ka dib marka la furo foostada qaybta A, waa in si fiican loo walaaqaa, ka dibna ku shub qaybta B ee qaybta A ee hoos walaaqaya si waafaqsan shuruudaha saamiga, si fiican u walaaq, u dhaaf inay istaagto oo kariso 30mins, ka dibna ku dar qadar ku habboon oo khafiif ah oo hagaaji. waxay u socotaa 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).
Ka taxadaritaan
- 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.
