Iyini i-geomembrane?

I-Geomembrane iyimpahla ye-geomembrane eyakhiwe ngefilimu yepulasitiki njenge-substrate engangeni kanye nendwangu engalukiwe.Ukusebenza okungenakunyakaziswa kwezinto ezintsha ze-geomembrane kuncike kakhulu ekusebenzeni okungenamandla kwefilimu yepulasitiki.Amafilimu epulasitiki asetshenziselwa ukuvimbela ukuphuma kwamanzi ekhaya naphesheya ikakhulukazi ahlanganisa i-polyvinyl chloride (PVC), i-polyethylene (PE), ne-EVA (ethylene/vinyl acetate copolymer).Kuzinhlelo zokusebenza zomhubhe, kukhona nemiklamo esebenzisa i-ECB (i-ethylene acetate modified asphalt blend geomembrane).Ziyizinto eziguquguqukayo zamakhemikhali e-polymer ezinobunzima obuthile obuthile, ukunwebeka okuqinile, ukumelana nokuguquguquka okuphezulu, ukumelana nokugqwala, ukumelana nezinga lokushisa eliphansi, nokumelana nesithwathwa okuhle.

I-Geomembrane iyinto engangeni manzi futhi iyisithiyo esekelwe ku-polymer.

Ihlukaniswe kakhulu ngokuthi: i-low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane, kanye ne-EVA geomembrane.

1. Ukucaciswa kobubanzi nokujiya kuqediwe.

2. Inokumelana okuhle kakhulu nokucindezeleka kwemvelo kanye nokumelana nokugqwala kwamakhemikhali okuhle kakhulu.

3. Ukumelana nokugqwala kwamakhemikhali okuhle kakhulu.

4. Inebanga lokushisa elikhulu lokusebenza kanye nempilo ende yesevisi.

5. Isetshenziswa ezindaweni zokulahla imfucumfucu, izindawo zokugcina izinsalela, ukuvimbela ukugeleza komsele, ukuvimbela ukugeleza kwe-embanking, kanye namaphrojekthi wesitimela esingaphansi komhlaba.

Indlela yayo eyinhloko iwukuhlukanisa indawo yokuvuza kwedamu lomhlaba ngokungakwazi ukungena kwamanzi kwefilimu yepulasitiki, imelane nokucindezela kwamanzi futhi ivumelane nokuguquguquka komzimba wedamu ngamandla alo amakhulu okudonsa kanye nobude;Indwangu engalukiwe futhi iwuhlobo lwento emfishane ye-polymer fiber chemical material, eyakhiwe ngokubhoboza inaliti noma i-thermal bonding, futhi inamandla aphezulu nokunwebeka.Uma ihlanganiswa nefilimu yepulasitiki, ayikhulisi nje kuphela amandla aqinile kanye nokumelana nokubhoboza kwefilimu yepulasitiki, kodwa futhi ikhulisa i-coefficient yokungqubuzana kwendawo othintana nayo ngenxa yobuso obumangelengele bendwangu engalukiwe, ekhuthaza ukuzinza kwenhlanganisela. i-geomembrane kanye nongqimba oluvikelayo.Ngesikhathi esifanayo, banokuphikiswa okuhle kokugqwala kwamagciwane kanye nesenzo samakhemikhali, abesabi ukuguguleka kwe-asidi, i-alkali, nosawoti, futhi babe nempilo ende yesevisi lapho besetshenziswa endaweni emnyama.
