Filimka cad, LDPE = cufnaanta hoose ee Polyethylene, ama Polyethylene-cadaadiska sare, waa Polyethylene polymerized marka la eego xaaladaha cadaadiska sare, cufnaanta ayaa ka hooseeya 0.922.

HDPE= cufnaanta sare ee Polyethylene, ama Polyethylene korantada yar.Cufnaanta ka sarreeya 0.940.

Joomembrane madow inta badan waa HDPE(cufnaanta sare ee polyetylen) geomembrane, geomembrane cad waa inta badan LDPE(polyeetylene cufnaanta hoose) geomembrane.Farqiga u dhexeeya labadaba waa inta badan cufnaanta iyo waxqabadka, cufnaanta hore waa ka weyn tahay, cufnaanta dambe waa yar tahay, kan hore waxaa loo isticmaalaa qalabka injineernimada geotechnical, kan dambe waxaa loo isticmaalaa sida alaabada filimada khafiifka ah.

Black geomembrane geomembrane waa madow sababtoo ah geomembrane ee ku biiray wax soo saarka masterbatch madow, noocaan qaybaha masterbatch ee saamiga si ay ugu biiraan hababka wax soo saarka geomembrane, duruufaha caadiga ah, qadar yar oo masterbatch ah ayaa farsamayn kara tiro badan oo geomembrane ah, qaybaha masterbatch geomembrane waa mid aad u badan. fududahay in la farsameeyo, ma saameyn doonto dhibaatada tayada ee geomembrane.

Joomembrane cad waa sababta oo ah geomembrane gudaha lagu daray qaybo sayid oo cad, qaybo sayidyada cad ma saameyn doonaan tayada geomembrane.Joomembrane madow waxay cufnaanta iyo waxqabadka ka sarreeyaan LDPE-da cad ee geomembrane sababtoo ah intooda badani waa geomembrane HDPE.Geomembrane LDPE cad oo loo isticmaalo sida badeecooyinka balaastigga ah, isticmaalka sidoo kale waa mid ballaaran.

Sababtoo ah cufnaanta geomembrane madow ee HDPE ayaa ka weyn kan LDPE geomembrane cad, labada adeegsigu way kala duwanaan doonaan.Isbarbardhigga tayada guud ayaa sidoo kale loo baahan yahay in la barbardhigo iyadoo loo eegayo codsiga labada nooc ee isku midka ah ee dhismaha, ma aha in la barbardhigo dhererka labada (wax isbarbardhig la'aan).Si kala duwan ayaa loo isticmaalaa dhismayaal kala duwan, mararka qaarkoodna waxay bedel u yihiin midba midka kale.

Caddaan LDPE geomembrane marka loo eego madow HDPE geomembrane ayaa ka sii fiican, dabacsanaan iyo ka xoog badan yahay madow HDPE geomembrane, gaadho qeexida dhismaha mashruuca cad LDPE geomembrane waa jiil cusub oo ka mid ah qalabka xakamaynta seepage geotechnical, awoodda la qabsiga ee injineernimada la mid ah waxay noqon doontaa ka xoog badan madow. HDPE geomembrane, hadda injineero badan ayaa sidoo kale lagu arki karaa alaabta.

Sida kor lagu arki karo, geomembrane HDPE madow iyo LDPE geomembrane cad waxay leeyihiin codsiyo kala duwan oo mashruucyo kala duwan ah oo aan la soo koobi karin.Labada nooc ee alaabadu waxay leeyihiin awoodooda iyo daciifnimadooda.Tayada labadan alaab waa in la tixgeliyaa iyadoo lagu saleynayo jagooyin kala duwan.
