Dhumucda saxan midab leh iyo sida loo qaado midabka gariiradda midabka midabka leh

saxan midab lehPPGI/PPGL waa isku darka saxan bir ah iyo rinji, markaa dhumucdiisu ma waxay ku salaysan tahay dhumucda saxanka birta ama dhumucda alaabta la dhammeeyey?
Ugu horreyntii, aynu fahamno qaab-dhismeedka saxan midab leh oo loogu talagalay dhismaha:

(Isha sawirka: Internet)

Waxaa jira laba siyaabood oo lagu muujiyo dhumucdaPPGI/PPGL
Marka hore, dhumucdiisuna waxay dhammaatay ee saxan midab leh
Tusaale ahaan: dhumucdiisuna waxay dhammaatay 0.5mmxaashi midab leh, dhumucda filimka rinjiga ee 25/10 microns
Markaa waxaan ka fikiri karnaa substrate-ka midabka leh ( xaashida duuban ee qabow + dhumucda lakabka galvanized, dhumucda lakabka beddelka kiimikada waa la iska indho tiri karaa) dhumucdiisu waa 0.465mm.
0.4mm caadiga ah, 0.5mm, 0.6mm xaashi midab dahaarka ah, taas oo ah, dhumucdiisuna waxay dhammaatey ee alaabta la dhammeeyey, taas oo ku habboon in aan si toos ah u cabbirno.

Marka labaad, macmiilku wuxuu cayimay shuruudaha dhumucda substrate-ka midabka leh
Tusaale ahaan: dhumucda substrate ee saxan midabka 0.5mm, dhumucda filimka rinjiga ee 25/10 microns
Kadib dhumucda alaabta la dhammeeyey waa 0.535mm, haddii aad u baahan tahay inaad daboosho filimka PVC si aad u ilaaliso dusha sare ee guddiga, waxaan u baahanahay inaan ku darno dhumucda filimka, laga bilaabo 30 ilaa 70 microns.

Dhumucdiisuna waxay dhammaatay = substrate midab dahaar ah (warqad qabow oo duuban + lakab galvanized) + filimka rinjiga (Rinjiga sare + rinjiga dambe) + filimka PVC
Kala duwanaanshaha kiis ee kor ku xusan ee 0.035mm, waxaan aragnaa in dhab ahaantii ay tahay farqi aad u yar, laakiin isticmaalka baahida macaamiisha waa inay sidoo kale aad u taxaddaraan. Sidaa darteed, markaad dalbanayso, fadlan si faahfaahsan ugu wargeli baahida.

Sida loo doorto midabka gariiradda daboolan midabka
Xulashada midabka saxan dahaarka ah ee midabka leh: doorashada midabka ayaa inta badan ah in la tixgeliyo ciyaarta deegaanka ku xeeran iyo hiwaayadaha isticmaalaha, laakiin marka laga eego aragtida isticmaalka tignoolajiyada, dahaarka midabka iftiinka ee midabada si aad u dooratid margin weyn oo doorashada, waxaad dooran kartaa adkeysi sare oo ah pigments inorganic (sida titanium dioxide, iwm.), iyo dahaarka dahaarka laftiisa ayaa kor u qaadaya hufnaanta kuleylka xagaaga si hufan hooseeya, taas oo ah in la kordhiyo nolosha daaha Tani waxay faa'iido u leedahay kordhinta nolosha daboolka.
