Isithintelo soMphunga wePolyethylene
Ingcaciso yeMveliso
Inkampani yethu, iShanghai Yingfan Engineering Material Co., yenye yezona zinto zikhokelayo kwipolyethylene ezenza umqobo wamanzi eTshayina. Sinikezela ngeplastiki enyulu ye-polyethylene isithintelo somphunga phantsi kwe-sleb yekhonkrithi okanye emva kwebhodi yesamente okanye kwi-basement okanye iindonga ezingaphantsi. I-6mil/9mil/10mil/20mil/ezinye izithintelo zomphunga ze-polyethylene ziyafumaneka kunikezelo lwethu.

Isithintelo somphunga wePolyethylene Intshayelelo (icatshulwe kwiwiki)
Isithintelo somphunga (okanye isithintelo somphunga) yiyo nayiphi na imathiriyeli esetyenziselwa ukuthintela ukufuma, ngokwesiqhelo iplastiki okanye icwecwe lefoyile, elixhathisa ukusasazwa kokufuma eludongeni, emgangathweni, kwisilingi, okanye kwiindibano zophahla zezakhiwo ukunqanda ukujiya kwe-interstitial kunye nokupakishwa. Ngokobuchwephesha, uninzi lwezi zixhobo zizithinteli zomphunga kuphela njengoko zinemigangatho eyahlukeneyo yokungena.
Izixhobo zinezinga lokuhambisa umphunga (MVTR) omiselwa ngeendlela zovavanyo eziqhelekileyo. Iseti enye yeeyunithi yi-g/m²·day okanye g/100in²·day. I-Permeability inokuxelwa kwi-perms, umlinganiselo wesantya sokudluliselwa komphunga wamanzi ngesixhobo (1.0 US perm = 1.0 grain / square-foot· iyure · intshi yemercury ≈ 57 SI perm = 57 ng / s · m2 · Pa ). Iikhowudi zokwakha zaseMelika zihlele iiretarders zomphunga njenge-permeance yomphunga wamanzi we-1 perm okanye ngaphantsi xa ivavanywa ngokuhambelana ne-ASTM E96 desiccant, okanye indlela yekomityi eyomileyo. Imathiriyeli yokunciphisa umphunga idla ngokuhlelwa ngolu hlobo:
I-impermeable (≤1 US perm, okanye ≤57 SI perm) - njengephepha le-asphalt-backed kraft paper, i-elastomeric coating, i-vapor-retarding paint, i-oil-based paints, i-vinyl wall coverings, i-polystyrene ekhutshwe, i-plywood, i-OSB;
I-Semi-permeable (i-1-10 US perm, okanye i-57-570 SI perm) - njenge-polystyrene eyandisiweyo engabonakaliyo, i-fiber-faced isocyanurate, amaphepha okwakhiwa kwe-asphalt-impregnated enzima, ezinye iipende ezisekelwe kwi-latex);
Ivumelekileyo (> 10 US perm, okanye > 570 SI perm) – njengebhodi yegypsum engapeyintwayo kunye nodaka, ukugqunywa kweglasi yefiber engajonganga, ukugqunywa kwecellulose, istucco esingapeyintwayo, iisheaths zesamente, ipoliolefin ephothiweyo okanye iifilimu zangaphandle zesithintelo somoya ezisekelwe kwipolymer.
Isithintelo somphunga sePolyethylene: Isithintelo somphunga sepolyethylene esixinana kakhulu
Singumvelisi owaziwayo we-polyethylene ephezulu yoxinaniso lomqobo womphunga wamanzi e-China. imveliso yethu permeability ngaphantsi ≤1.0×10-13 g•cm(cm2)•pa. Ngoko ke ingahlelwa njengesithintelo somphunga esinganyangekiyo. Ubomi bayo bunokuhlala ngaphezulu kweminyaka engama-70 kwesi sicelo. Ububanzi bunokufikelela ngaphezu kwe-8m kwaye ubude bungafikelela ngaphezu kwe-800m.

Ubungqina bobumanzi buyinxalenye ebaluleke kakhulu yokugcina ukuqina kwesakhiwo sokwakha xa kuyilwa ukwakhiwa. Ipropathi yethu eguquguqukayo kunye nelungileyo engenakungeneka yesithintelo sethu sokufuma se-polyethylene ibonakaliswe kwiiprojekthi ezininzi zokuthintela umphunga zomgangatho kunye neendonga kwakhona kwaye kwakhona.
Ngexabiso lokuthintela umphunga we-polyethylene, unokucebisa ukuthengisa kwethu ngokwesixhobo sethu sokuncokola kwi-Intanethi okanye olunye unxibelelwano.
