Ngaba ukhathazekile malunga nokukhetha isixhumi esingafanelekanga kwiintambo zakho zamanzi? Ukufakelwa okungahambelaniyo kumbhobho we-PE kunokukhokelela ekuvuzeni, ekulahlekelweni koxinzelelo, kunye nokulungiswa okubiza kakhulu nokuphazamisayo.

Izixhobo ze-PEzizixhobo zokuqhagamshela ezenzelwe ngokukodwa iipayipi zePolyethylene (PE). Zenza iindawo ezikhuselekileyo zokudibanisa ezi zinto ziguquguqukayo nezihlala ixesha elide zisebenzisa iindlela ezifana nokucinezelwa ngoomatshini okanye ukuhlanganiswa kobushushu, ukuqinisekisa ukuba imibhobho okanye inkqubo yokunkcenkceshela ayivuzi kwaye ihlala ixesha elide.

Ukuthembeka kwayo nayiphi na inkqubo yemibhobho kuxhomekeke ekuqhagamshelweni kwayo. Njengomntu owakhe inkampani ekumgangatho wehlabathiizisombululo zolawulo lwamanziNdiyazi ukuba umbhobho unamandla kuphela xa udibene nobuthathaka. Kumphathi wokuthenga onjengoCarlos, ukugcina izixhobo ezifanelekileyo akupheleli nje ekuzalisekiseni iodolo; kumalunga nokubonelela ngezinto eziqinisekisa ukuthembeka kwenkqubo kangangeminyaka emininzi.

I-PE imele ntoni kwizixhobo zokufaka iipayipi?

Ngaba uyalibona igama elithi “PE” kwii-spec sheets kwaye uzive ungaqinisekanga? Uku-odola ngokusekelwe kuqikelelo kunokukhokelela kwizixhobo ezingahambelaniyo, ukulibaziseka kweprojekthi, kunye nokuchithwa kwezinto ezikhoyo.

I-PE imele nje iPolyethylene. Yi-thermoplastic eqinileyo, eguquguqukayo, nengagqwaliyo esetyenziselwa ukwenza imibhobho yamanzi, ukunkcenkceshela, kunye nokusasazwa kwegesi. Izixhobo ze-PE zizihlanganisi ezenzelwe ukudibanisa le mibhobho ithile.

Ndisoloko ndixelela iqela lam ukuba ukucaca kubonakalisa ububele. Ukusebenzisa amagama alula kunceda wonke umntu enze izigqibo ezingcono. Xa uCarlos eqonda ukuba i-PE ithetha iPolyethylene, unokuthetha ngokuzithemba ngakumbi nabathengi bakhe, ukusuka kubakhi abakhulu ukuya kubalimi basekuhlaleni. Akangomthengisi nje kuphela; ungumkhokeli ochwephesha, oqinisekisa ukuba abathengi bakhe bafumana isisombululo esiqinileyo nesiguquguqukayo esibonelelwa yiPolyethylene kwiimfuno zabo ezithile, ngakumbi kwiindawo ezingaphantsi komhlaba okanye ezifuna kakhulu.

Ukuqonda Indima yePolyethylene

I-Polyethyleneluhlobo lweplastiki olubizwa ngokuba yi-i-thermoplastic, oko kuthetha ukuba inokunyibilikiswa kwaye ilungiswe. Le propati iphambili kwezinye zeendlela zayo zokudibanisa. Ukuthandwa kwayo kwimibhobho yamanzi kuvela kwiingenelo zayo eziphambili kunezixhobo zemveli ezifana nesinyithi. Ayigqwali okanye ibole ngenxa yeekhemikhali ezisemhlabeni okanye emanzini, kwaye ukuguquguquka kwayo kuvumela ukuba ifakwe ngamalunga ambalwa, nto leyo enciphisa iindawo ezinokubangela ukuvuza.

Ubuninzi obahlukeneyo bemisebenzi eyahlukeneyo

Ayizizo zonke iindlela zokucoca ezilinganayo. Umahluko ophambili oza kuwubona bubuninzi bayo. Oku kubalulekile ekukhetheni umbhobho ofanelekileyo womsebenzi.

Uphawu	I-HDPE (iPolyethylene enoxinano oluphezulu)	I-LDPE (iPolyethylene eNcinci)
Ulwakhiwo	Uqinile ngakumbi kwaye unzima	Ithambile kwaye iguquguquka ngakumbi
Uvavanyo loxinzelelo	Phezulu	Ezantsi
Ukusetyenziswa Okuqhelekileyo	Imigca ephambili yokuhambisa amanzi, imigca yegesi, imigudu yamandla	Ukunkcenkceshela ngoxinzelelo oluphantsi, iityhubhu zokuthontsiza, imigca enobubanzi obuncinci
Inkangeleko	Idla ngokuba mnyama oqinileyo, ngamanye amaxesha ibe nomgca onemibala	Ngokwesiqhelo imnyama eqinileyo, ivakala ithambile xa uyichukumisa

KuCarlos, ukugcina izixhobo zokufaka ezilinganiswe yi-HDPE kunye nezixhobo zokufaka ezihambelana ne-LDPE kumvumela ukuba akhonze abathengi abaninzi, ukusuka kwiiprojekthi zamanzi zikamasipala ukuya kwiinkqubo zokunkcenkceshela kwezolimo.

Zeziphi izixhobo ozisebenzisayo kwipayipi ye-polyethylene?

Unombhobho ofanelekileyo, kodwa ungayidibanisa njani ngaphandle kokudala indawo ebuthathaka? Ukusebenzisa uhlobo olungalunganga lokufakela yindlela eqinisekisiweyo yokuvuza kunye nokusilela kwenkqubo.

Iintlobo ezintathu eziphambili zokufakelwa kwepayipi ye-PE zezoomatshiniizixhobo zokucinezela, izixhobo zokudibanisa iimpundukunyeizixhobo zokudibanisa ngombaneOlona khetho lufanelekileyo luxhomekeke kububanzi bombhobho, iimfuno zoxinzelelo, kunye nokuba ijoyinti kufuneka ihlale ihleli na.

Ndibone iiprojekthi ezixabisa izigidi zeerandi zixhomekeke ekuthembekeni kwezi zixhobo. Ukukhetha kubaluleke kakhulu. Ukufakelwa okulula koxinzelelo kulungile kumgca wokunkcenkceshela igadi. Kodwa kumthombo wamanzi wesixeko oxinezelekileyo ogqunywe phantsi kwesitalato, udinga uqiniseko olupheleleyo lweukuwelda kwe-fusionUkukhokela umthengi kukhetho olufanelekileyo, njengoko uCarlos esenza, kuthintela iintlekele zexesha elizayo kwaye kwakha ukuthembana okukhulu.

Izixhobo zoxinzelelo lweMechanical

Ezi zezona ndlela zilula ukuzisebenzisa. Zisebenza njengesikrufu. Utyibiliza i-nut kunye neringi yokubamba phezu kombhobho, ufake isiqinisi ngaphakathi kombhobho, uyityhale emzimbeni ofanelekileyo, uze uyiqinise i-nut. Oku kuyayicinezela iringi, kwenze isitywino esingangeni manzi. Zilungele ubukhulu obuncinci (ngesiqhelo ukuya kuthi ga kwi-intshi ezi-4 okanye i-110mm), ukulungiswa, kunye nokusetyenziswa ngaphezulu komhlaba. Inzuzo yazo ephambili kukuba azidingi zixhobo zikhethekileyo kwaye kulula ukuzifaka okanye ukuzisusa.

Izixhobo zokudibanisa ubushushu

Kwimibhobho emikhulu kunye nokusetyenziswa koxinzelelo oluphezulu, ukuhlanganiswa kobushushu yeyona ndlela iqhelekileyo. Le nkqubo ngokusisiseko iyanyibilikisa umbhobho kwaye idibane ibe yiplastiki enye eqhubekayo, idale ijoyinti eqinileyo njengombhobho ngokwawo.

Uphawu	Ukuhlanganiswa Kweempundu	Ukudibanisa nge-Electro
Inkqubo	Iiphelo zepayipi kunye nokufakelwa zifudunyezwa kwipleyiti zize zityhalelwe kunye.	Kusetyenziswa isixhobo esinee-heating coils ezakhelwe ngaphakathi. Umatshini uthumela umbane kwii-coils, unyibilikise iplastiki ngaphakathi nangaphandle.
Izixhobo	Umatshini omkhulu, wokudibanisa izinqe ze-hydraulic.	Iprosesa encinci, ephathekayo ye-electrofusion.
Eyona ndlela ilungileyo yokusebenzisa	Imibhobho emide, ethe tye yobubanzi obukhulu kwimisele evulekileyo.	Ukulungiswa, iindawo ezixineneyo, ukuqhagamshela kwimigca ekhoyo, okanye nayiphi na imeko apho ukuhambisa umbhobho kunzima khona.

Kwimpahla kaCarlos, izixhobo zokucinezela ziyimfuneko kwintengiso yemihla ngemihla. Ukugcina izixhobo zokudityaniswa kunye nokufikelela kwizixhobo kumenza abe ngumthengisi weeprojekthi ezinkulu zeziseko zophuhliso.

Ngaba i-PE iyafana ne-PEX?

Ngaba uphatha i-PE kunye ne-PEX ngokungathi zizinto ezifanayo? Oku kudideka kuqhelekileyo kunokukhokelela ekusileleni okukhulu kokufakelwa, ingakumbi xa kubandakanyeka amanzi ashushu.

Hayi, azifani. I-PE yiPolyethylene. I-PEX yiPolyethylene eQokelelweyo. Inkqubo "yokudibanisa" inika i-PEX ukumelana nobushushu obuphezulu kakhulu, nto leyo eyenza ukuba ibe ngumgangatho wemigca yamanzi ashushu nabandayo ngaphakathi kwezakhiwo.

Ndakha ndabonisana ngetyala apho umakhi wayesebenzisaUmbhobho we-PEukuze kuqhagamshelwe isifudumezi samanzi ashushu kuba sasitshiphu. Umbhobho wathamba waza waqhuma kwisithuba seveki, nto leyo eyabangela umonakalo omkhulu emanzini. Lo ngumzekelo ogqibeleleyo wokuba kutheni lo mahluko ubalulekile. Kumphathi wokuthenga onjengoCarlos, ukuchaza lo mahluko akupheleli nje ekuthengiseni; kukuthintela impazamo eyingozi nebiza kakhulu kubathengi bakhe.

U-“X” ngumahluko ophambili

Igama elithileukudibanisa okunqamlezileyoIvakala inzima, kodwa yingcamango elula. Khawucinge ngeeleli ezimbini ezihambelanayo (iintambo ze-PE polymer). Ngoku, khawucinge ngokongeza iileyidi phakathi kwezo leyidi zimbini. Oko kukudibanisa. Oku kudala isakhiwo se-molecular esomeleleyo nesizinzileyo esinokuphatha ubushushu kunye noxinzelelo oluphezulu ngaphandle kokuguquka. I-PE ayinazo ezi "leeyididi," ngoko ke iya kuthamba kumaqondo obushushu apho i-PEX ihlala inamandla.

I-PE vs. i-PEX: Uthelekiso olucacileyo

Uphawu	I-PE (iPolyethylene)	I-PEX (iPolyethylene eDibeneyo)
Ukusetyenziswa Kwamanzi Ashushu	Hayi, ayifanelekanga emanzini ashushu.	Ewe, ilungele kakhulu amanzi ashushu nabandayo.
Isicelo esiPhambili	Imibhobho yamanzi engaphantsi komhlaba, ukunkcenkceshela, imigca yegesi.	Ukufakelwa kwamanzi ngaphakathi endlwini kwizindlu nakwizakhiwo zorhwebo.
Izixhobo	Uxinzelelo, Ukuhlanganiswa Kweempundu, Ukuhlanganiswa Kwe-Electro.	I-Crimp, i-Clamp, i-Expansion, i-Push-to-Connect.
Ukuguquguquka	Iguquguquka kwii-arcs ezinkulu.	Iguquguquka kakhulu, inokwenza ukugoba okuqinileyo.
Ukumelana ne-UV	Ngokubanzi ilungile (umnyama yeyona ilungileyo).	Imbi, akufuneki ibekwe elangeni.

Ukuyazi le theyibhile ngentloko kubalulekile kuye nabani na okwishishini lokuhambisa imibhobho. Kuqinisekisa ukuba ubonelela ngezinto ezifanelekileyo zomsebenzi ofanelekileyo, ngalo lonke ixesha.

Isiphelo

Izixhobo ze-PEqhagamshela umbhobho wePolyethylene usebenzisa iindlela zokucinezela okanye zokudibanisa. Zahlukile kwi-PEX fittings, ezenzelwe amanzi ashushu. Ukukhetha uhlobo olufanelekileyo kuqinisekisa inkqubo eqinileyo, engenamanzi.
