HDPE tube: izici futhi izicelo

izesekeli Plastic ngokulungisa amapayipi amanzi ebonakala ezweni lethu mayelana phakathi 90s kwekhulu elidlule, okwathi ngemva kwalokho cishe ngokushesha esikhundleni ayina steel nozakwabo. Lokhu kuyiqiniso ikakhulukazi ngokuphathelene amapayipi amanzi. Kunengqondo ukuphetha ngokuthi kulesi sikhathi HDPE ipayipi (izici okuyinto thina uchaze ngezansi), babengafuni ukulandela babonisa ukuthi kukhulu, kodwa abanye bethu namanje kukhona noplastiki zokungabaza ezithile. Asikhulume kabanzi mayelana lo mkhiqizo.

Kusukela ukuthi lezi amashubhu ekhiqizwa?

Ubuchwepheshe ukukhiqiza yokuthi ethylene molecule crosslinking inqubo kwenzeka ngesikhathi ingcindezi 5 kg / cm ^2. Kwakheka impahla nge kwabantu of 0,941 g / cm, kokuba ukuqina ezinhle. Ngenxa isakhiwo crystal, kuba opacity ezahlukene. Njengoba sazi ukuthi ethylene ixhunywe ku-molecule compact amagatsha kancane, amandla impahla okuholela kuphezulu kakhulu. HDPE liyancibilika at lokushisa mayelana 130, ukuze ukusetshenziswa okujwayelekile imikhiqizo ukukhulula bengasayesabi ukwehluleka ngenxa isici lokushisa kufanele yini. Ngakho, HDPE igemfe, izici yiziphi ngakho okuhle, ephelele yangasese amakhaya amanzi ompompi.

Ngaphezu kwalokho, it has ukumelana enhle kakhulu acid kanye amafutha, okwenza amapayipi enjalo ikhandidethi elilungile lokukhuphula yesidala hhayi kuphela, kodwa futhi indle. Kufanele kuqashelwe ukuthi kungabuye aqhephukile, kodwa ngokusebenzisa izimpawu ephezulu yamangqamuzana ngeke kwenzeke ngaphansi kwezimo ezithile. Ngomqondo onabile, HDPE ipayipi, izici okuyizinto ngempela aphakeme, kusetshenziswa khona okushisa afinyelela ku -50 degrees Celsius.

Ngaphezu kwalokho, HDPE ikhiqizwa emaphaketheni ifilimu, amapayipi kanye ukwahlukanisa ephezulu zikagesi onamandla amakhulu, amanetha ngoba ezicijile, ifenisha kanye ifenisha uqobo, kanye uhlu omkhulu eminye imikhiqizo.

I izici eziyinhloko komkhiqizo

Nokho, sinesithakazelo kungasiko izakhiwo lobuchwepheshe amanetha nezinsiza, njengoba ngqo amaphayiphi ngokwabo. Ake sibheke kubo kabanzi.

Okokuqala, ekuphileni kwabo inkonzo - okungenani amahlanu. Bemithi-50 leminyaka eledlule wabeka ukuzinza anjalo design yabo. Njengoba sishilo, bona bangaveziwe nolaka chemical ezindaweni. Ngaphezu kwalokho, amapayipi eyenziwe polyethylene akuzona imisinga ehlangeni, kuyilapho amapayipi metal zingadilizwa kubo zezinkathi eziningana kuphela. Ngisho izindleko zabo laying ngezansi cishe umyalelo ezidlula: ekugcineni, uma kunesidingo, ukuba sibhekane nale uhlobo lomsebenzi, ngisho umuntu oyedwa. Futhi konke lokhu - HDPE ipayipi. umkhuba Technical ukusetshenziswa kwabo kuye kwabonisa ukuthi ngisho ukugqwala kungukuthi kwakhiwa, ukuze isidingo ngezibhakela futhi umonakalo empahleni bangakhohlwa ngokuphepha.

Qaphela ukuthi ngisho ngesikhathi aphansi kakhulu okushisa kuma, okuyizinto ezibangela ukudabuka imikhiqizo metal ejwayelekile, polyethylene uhlala ngokuphelele bengenamiyocu kulesi sigameko. Lokhu kungenxa yokuthi i-conductivity ezishisayo kwale nto liphansi kakhulu. Yingakho HDPE ipayipi (izici okuyinto sibuyekeze) Kungenzeka ukuthi bayazi kahle ngokulinganayo isetshenziswe kuphela sezulu esipholile, kodwa futhi ku eNyakatho Ekude. By the way, ngisho ngaphansi kwamazinga okushisa aphansi kakhulu, nxa amanzi namanje simisiwe ngaphakathi umkhiqizo, lutho ezimbi kuzokwenzeka: a polyethylene ukuba kwande ngamaphesenti 5-7%, ukuze iqhwa ngeke bakwazi ukudiliza zayiqeda.

Lezi izindawo ekwazi ukumelana enhle kakhulu waterhammer, kangangokuthi ngisho Antics kwemisebenzi yomphakathi akusho ukwesabisa kwakho. Uma kwenzeka okuthile, ukukhanda ngeke kuthathe isikhathi esiningi. Ngaphezu kwalokho, HDPE igemfe, izici okuyinto futhi uvumele Welding yayo, nge sikhathi akaphelelwa amandla ngisho welds.
