Daawaynta lakabka sare ee birta ilaa heerka Sa2.5, qallafsanaanta dusha sare 30um-75um.
Qalabka korontada oo hoos u dhacaya ilaa heerka St3.

Waxaa lagu dabaqi karaa dhismayaasha birta ah, haamaha saliidda, haamaha saliidda, qalabka kiimikada ee ka hortagga daxalka, qalabka korontada ku shaqeeya, gawaarida gaadiidka sida dahaarka ka hortagga miridhku.

Si toos ah ayaa loogu rinjiyeeyay dusha sare ee birta iyadoo tayada ka saarista miridhku ay gaarayso heerka Sa2.5.

Rinjiga birta ah ee midabaysan ee Polyurethane, rinjiga polyurethane, jaakadda sare ee polyurethane ee acrylic, jaakadda sare ee fluorocarbon.

Dhumucda filimka lagu taliyay: 60-80um
Qiyaasta aragtida: qiyaastii 115g/m² (oo ku salaysan 35um filim qalalan, marka laga reebo khasaaraha).
Tirada jaakadaha la soo jeediyay: 2 ~ 3 jaakadood
Heerkulka kaydinta：-10~40℃
Heerkulka Dhismaha: 5~40℃
Muddada tijaabada: 6 saacadood
Habka dhismaha: Cadayasho, buufinta hawada, duubista ayaa la isticmaali karaa.
Kala fogaanshaha rinjiyeynta:
Heerkulka substrate-ka ℃ 5-10 15-20 25-30
Mudada gaaban 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, waana in aan la dhisin.

Ka dib marka la furo foostada qaybta A, waa in si fiican loo walaaqo, ka dibna kooxda B ku shub qaybta A iyadoo la walaaqayo iyadoo la raacayo shuruudaha saamiga, si fiican isku qas oo u daa inay bislaato 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).
Dahaarka duuban: Tirada milmidu waa 5-10% (marka la eego saamiga miisaanka rinjiga).

Dhismaha xilliga heerkulka sare, buufinta si fudud loo qalajin karo, si looga fogaado buufinta qalalan waxaa lagu hagaajin karaa buufin khafiif ah ilaa aan qalalanayn.
Badeecadan waa in ay isticmaalaan xirfadlayaasha rinjiyeynta sida ku cad tilmaamaha ku qoran baakadka alaabta ama buug-gacmeedkan.
Dhammaan dahaarka iyo isticmaalka badeecadan waa in loo fuliyaa si waafaqsan dhammaan xeerarka iyo heerarka caafimaadka, badbaadada iyo deegaanka ee khuseeya.
Haddii aad shaki ka qabtid in badeecadan la isticmaali karo iyo in kale, fadlan la xiriir waaxdayada adeegga farsamada si aad u hesho faahfaahin.
