Imibhobho polyethylene: zento emayenziwe kunye nenkcazo

Kutshanje, ukusetyenziswa kwemibhobho zeplastiki ukuba ugutyulo, amanzi okanye ukufudumeza njengento ubutsha, kodwa namhlanje baye bafumana zisetyenziswe kakhulu ngokubanzi. Imibhobho polyethylene, iimpawu yobugcisa zahlukile kakhulu ebuntsimbi lwabo ukukhonza iinkosi zabo kunye neminyaka maxa wambi ngaphezu kwama-50. Ngoko ke yintoni na phawu wabo?

Isishwankathelo lemibhobho polyethylene

Uncedo lokuqala kunye ephambili yale inqawe ukuxhathisa wayo umhlwa. Enkosi kubo, banako ukuphila ngaphandle wokulungisa ixesha ngokwaneleyo elide. Ngaphezu koko, polyethylene njengogwali ngenxa sonikezelo lwamanzi kunye nothungelwano lwemijelo abalindelekanga phantsi umhlwa galvanic. Inxalenye engaphakathi egudileyo zabo, nto leyo ngokuphawulekayo ukwandisa bandwidth. Nasemva kweminyaka emininzi yokusebenza lemibhobho polyethylene sonikezelo lwamanzi, ukufudumeza okanye nothungelwano lwemijelo kwahluka yokupasa ngcono kakhulu intsimbi, ngenxa yokuba lo iidiphozithi musa kuhlala phezu kweendonga zawo. Izixhobo anokwenziwa hayi zeplastiki kuphela, kodwa isinyithi. Ngaphezu koko, amafu phezu awukwazi kuyilwa. Ezi iingenelo benza imibhobho polyethylene (iinkcukacha ziya ezichazwe ngezantsi) ithandwa kangaka.

Izimilo imibhobho polyethylene

Xa siqwalasela imibhobho polyethylene (iinkcukacha), umjelo, amanzi okanye ukufudumeza, kufuneka kuqala anikele ingqalelo uhlobo umbandela esetyenziswa ukwakhiwa kwawo, ngoko uthethe malunga nokwenziwa yenkcaso umbhobho kwingcinezelo ngaphakathi kwi sangqa kwimveliso. Kungenxa yoko le nto, ukuba ufuna ukufunda okungakumbi ngoko umbhobho polyethylene, iimpawu zobugcisa befunda yaye ngokukodwa, kufuneka kuqala baqhelane yintoni polyethylene brand:

1. PE 63 (hayi isetyenziswa njalo kude).
2. PE 80 - uye iipropati elungileyo kwaye ukumelana kakhulu eninzi ulwelo yengcinezelo naluphi na uhlobo. Olu phawu isetyenziswa ekudalweni kwemibhobho omncinci ukuba babekwa ukuze ubonelelo lwamanzi.
3. PE 100 - ezisetyenziselwa ukwenza imibhobho ubukhulu becala, ezisetyenziswa kulwakhiwo emikhulu ezinawo amanzi abandayo.

Ububanzi, nto leyo kwakhona zibandakanyiwe iimpawu imibhobho polyethylene ingaba nomahluko ngokupheleleyo. Lebanga-20 mm ukuya kwi-120 cm. Ubude yabo ixhomekeke kwindlela na ubukhulu. Umzekelo, ityhubhu bepali of mm-20 ukuya 110 lucebisa ukuba ubude balo akufuneki ube ngaphezu kweemitha ezingama-50.

Izinto eziluncedo ze imibhobho zeplastiki of ubukhulu enkulu

Kutshanje, imfuno inkulu ezizezi umbhobho omkhulu. Oku kuchazwe ngenxa yokuba zisetyenziselwa ukwakha inkqubo xinzelelo amanzi, inkqubo yokukhupha amanzi, esitshi okanye umjelo. Baye izinto eziliqela ezibalulekileyo phezu imifanekiso metal:

1. Imveliso, ufakelo kunye nokusebenza zibiza imali eninzi kwimeko zesinyithi.
2. Ukuba amanzi ngumkhenkce ngaphakathi, ngoko ke akuyi kubakho nto iphosakeleyo ngaloo nto.
3. Ubunzima umbhobho usezantsi kakhulu, ngoko uthutho kunye nofakelo lula.
4. pipe polyethylene Technical ekhuselekileyo ubuthi.
5. Ngexesha zokuhamba akukho mfuneko yokuba ungakhathazeki, njengoko na iimpahla ezinobungozi.
6. Ukumelana ukuba nefuthe kwaye akhululeke. Uqhagamshelo zinokuthenjwa ngakumbi kwaye ixesha elide, nto leyo eyandisa ubomi wenkonzo umbhobho.

imibhobho polyethylene

Ngenxa polyethylene lokulawula amanzi onelungelo ujongo entsha ngcono kakhulu ubulunga bayo. Isibakala sokuba PE kunceda ekuphuculeni uphuhliso kwenkqubo, kunye nokwakhiwa oko kwenzeka ngamaxesha lula nangokukhawuleza. Umzekelo, ungasebenzisa i trenchless ekuthiwa ngokubekwa. imibhobho polyethylene, iimpawu zobugcisa kubanceda ukuba kuchaphazeleka ngisho imichiza enamandla, kube lula kuthuthwa yaye ekhwele. uqhagamshelo yabo ixesha elide kakhulu yaye ithembekile, nto leyo inceda ukukhusela nxamnye neengozi.

imibhobho incence ezenziwe polyethylene

Olu hlobo ityhubhu ukuba imibhobho yamanzi kunye imisele ezenziwa umaleko ezizodwa ezimbini polyethylene. Ngokuqhelekileyo, basebenzisa brand PE-80, nto leyo ubukhulu na izityalo kule modeli. Imibhobho abamelana imichiza. Ngenxa ngumkhinkqi ekhethekileyo umsesane, noko iphezulu ngokwaneleyo, ityhubhu yeplastiki incence ingafakwa ngokusebenzisa indlela yokugungxula kubunzulu yeemitha omnye ukuya mabini. Kukho imibhobho incence eyenziwe polyethylene, kwaye babizwa ngokuba imisele sewer lwangaphandle.

umbhobho uxinzelelo ugutyulo amanzi

Mark PE 80 yeyona eside kakhulu ezaziwayo ukuza kuthi ga ngoku. Kungenxa yoko le nto isetyenziswa ukwenza wesizalo zeplastiki ezizodwa into enokumelana zombini koxinzelelo oluphezulu nezisezantsi. Zinokusetyenziswa ngaphandle iingxaki nkqu kwiindawo nomsindo gqitha, kodwa kwingingqi engundoqo isicelo ngamanzi ngxi. ukuba ayifanelekanga ukuba isetyenziselwe yamanzi. Eyona ethandwayo namhlanje sangqa imibhobho cm 2 ukuya 6.3.

abenzi-waziwa kakuhle ngemibhobho polyethylene

Ezivenkileni DIY namhlanje yi-ntlobo omkhulu kunye noluhlu polyethylene kwemibhobho amehlo ukubaleka nje kude. Ukuba awuyazi ukuba uhlobo pipe kungcono ukufumana, simele kuqala ukufumana owenza model data.

Le nkampani ithandwa kakhulu ekuveliseni kwemibhobho polyethylene ukuba ilindle kunye nonikezelo lwamanzi namhlanje Rehau. Oku kudala ezikumgangatho ophezulu kunye neemveliso ngokwaneleyo irobust ezongeziweyo ezifanelekileyo amanzi amdaka neenkqubo zayo nayiphi nokuba ubude. Ngaphezu koko, umbhobho polyethylene itephu, iimpawu ephakamisa umgangatho walo ophezulu, kuba ibandla lula, ukuthuthwa lula kunye lula le nkqubo.

Ukusuka Holland Company Wavin uvelisa wesizalo polyethylene ngenxa yamanzi amdaka. Ngokukhetha le nkampani, uya kukulibala ixesha elide, ukuba ukulungiswa okunjalo. Eyona iphambili imibhobho polyethylene Wavin kukuba ingxolo ephezulu zokwambathisa mihlaba kwaye ukumelana amaqondo obushushu aphezulu (ukuya kwi 90 degrees).

abenzi Russian kwakhona emva imibhobho amazwe novelisa of polyethylene kwizinga eliphezulu Imfono-ebizwa ngokuba uxinzelelo eliphantsi. Le modeli ukufaka i ngexabiso eliphantsi, ngoko ke athandwa kakhulu phakathi abakhi kunye nabathengi.
