*Astaamaha Badeecada:
Iska caabin kiimiko oo wanaagsan iyo iska caabin biyo
Waxay u adkaysataa saliidaha macdanta, saliidaha khudradda, dareerayaasha batroolka iyo waxyaabaha kale ee batroolka
Filimka rinjigu waa mid adag oo dhalaalaya
Filimku wuu kulul yahay, ma daciifo, ma dhegdhegna
*Xogta Farsamada:
| Shay | Heerka Caadiga ah |
| Waqtiga Qalalan (23℃) | Dusha sare ee qalalan≤2h |
| Qallalan adag≤24h | |
| Viscosity (dahaarka-4), s) | 70-100 |
| Cimri, μm | ≤30 |
| Xoogga saameynta, kg.cm | ≥50 |
| Cufnaanta | 1.10-1.18kg/L |
| Dhumucda filimka qalalan, um | 30-50 um/lakabkiiba |
| Dhalaal | ≥60 |
| Barta iftiimaysa, ℃ | 27 |
| Mawduuc adag,% | 30-45 |
| Adkaanta | H |
| Dabacsanaan, mm | ≤1 |
| VOC,g/L | ≥400 |
| Iska caabbinta alkaline, 48 saacadood | Xumbayn, diirid la'aan, iyo duuduub la'aan |
| Iska caabbinta biyaha, 48 saacadood | Xumbayn, diirid la'aan, iyo duuduub la'aan |
| Iska caabbinta cimilada, gabowga degdega ah ee macmal ah muddo 800 saacadood ah | Ma jiro dildilaac muuqda, midab beddel ≤ 3, lumis iftiin ≤ 3 |
| Ceeryaamo u adkaysta milixda (800h) | wax isbeddel ah kuma iman filimka rinjiga. |
*Isticmaalka Badeecada:
Waxaa loo isticmaalaa mashaariicda ilaalinta biyaha, haamaha saliidda cayriin, daxalka kiimikada guud, maraakiibta, dhismayaasha birta ah, dhammaan noocyada dhismayaasha shubka ah ee u adkaysta qorraxda.
*Rinji isku mid ah:
Waxaa loo isticmaalaa mashaariicda ilaalinta biyaha, haamaha saliidda cayriin, daxalka kiimikada guud, maraakiibta, dhismayaasha birta ah, dhammaan noocyada dhismayaasha shubka ah ee u adkaysta qorraxda.
*Daawaynta Dusha Sare:
Dusha sare ee qalabka ugu muhiimsan waa inay ahaataa mid nadiif ah, qalalan oo aan wasakh lahayn.
Fadlan fiiro gaar ah u yeelo muddada dahaarka ee u dhaxaysa dhismaha iyo aasaaska.
*Xaaladda Dhismaha:
Heerkulka substrate-ka kama hooseeyo 5 ℃, ugu yaraan 3 ℃ ayuu ka sarreeyaa heerkulka barta dharabka hawada, qoyaanka qaraabaduna waa <85% (heerkulka iyo qoyaanka qaraabadu waa in lagu cabbiraa meel u dhow substrate-ka). Dhismaha si adag ayaa looga mamnuucay ceeryaamo, roob, baraf, iyo cimilo dabayshu jirto.
Rinjiga hore u sii dahaadha rinjiga asaasiga ah iyo kan dhexe, oo qalaji badeecada 24 saacadood ka dib. Habka buufinta waxaa loo isticmaalaa in lagu buufiyo 1-2 jeer si loo gaaro dhumucda filimka la cayimay, dhumucda lagu taliyayna waa 60 μm. Ka dib dhismaha, filimka rinjiga waa inuu ahaadaa mid siman oo siman, midabkuna waa inuu ahaadaa mid isku mid ah, mana jiri doonto wax daadanaya, nabarro, diirka liinta iyo cudurrada kale ee rinjiga.
* Cabbiraadaha Dhismaha:
Waqtiga qalajinta: 30 daqiiqo (23 ° C)
Cimriga:
| Heerkulka, ℃ | 5 | 10 | 20 | 30 |
| Cimriga (h) | 10 | 8 | 6 | 6 |
Qiyaasta Khafiifka ah (saamiga miisaanka):
| Buufin aan hawo lahayn | Buufinta Hawada | Dahaarka burushka ama duubka |
| 0-5% | 5-15% | 0-5% |
Waqtiga dib u dahaadhka (dhumucda filim kasta oo qalalan 35um):
| Heerkulka deegaanka, ℃ | 10 | 20 | 30 |
| Waqtiga ugu gaaban, h | 24 | 16 | 10 |
| Waqtiga ugu dheer, maalin | 7 | 3 | 3 |
* Habka Dhismaha:
Buufinta: buufinta aan hawada lahayn ama buufinta hawada. Waxaa lagugula talinayaa inaad isticmaasho buufinta aan gaaska lahayn ee cadaadiska sare leh.
Burushka/dusha duuban: waa inuu gaaraa dhumucda filimka qalalan ee la cayimay.
* Tallaabooyinka badbaadada:
Fadlan fiiro gaar ah u yeelo dhammaan calaamadaha badbaadada ee ku yaal baakadka inta lagu jiro rarista, kaydinta iyo isticmaalka.
Qaado tallaabooyinka ka hortagga iyo ilaalinta lagama maarmaanka ah, ka hortagga dabka, ilaalinta qaraxyada iyo ilaalinta deegaanka.
Iska ilaali inaad neefsato uumiga dareeraha ah, ka fogow inaad rinjiga ku taabato maqaarka iyo indhaha.
Ha liqin badeecadan.
Haddii shil dhaco, isla markiiba raadso daryeel caafimaad.
Qashin-qubka waa inuu waafaqsan yahay xeerarka amniga ee dawladda dhexe iyo kuwa maxalliga ah.
*Xirmada:
Rinjiga: 20Kg/Baaldi;
Wakiilka Daaweynta/Adkeeyaha: 4Kg/Baaldi
rinjiga: wakiilka daaweynta/adag = 5: 1 (saamiga miisaanka)
