Uzama ukukhetha izinto ezifanele zamapayipi. Amakhodi afana ne-PE 80 kanye ne-PE 100 ayadida, futhi ukwenza ukukhetha okungalungile kungaholela ekwehlulekeni kohlelo kanye nokulungiswa okubizayo.

I-PE 100 iyisizukulwane sakamuva se-High-Density Polyethylene (HDPE). I-“100″ isho ukuthi inamandla adingekayo amancane (MRS) angu-10.0 MPa, okwenza ibe namandla kunezinto ezindala. Lokhu kuvumela amapayipi anezindonga ezincane ezisakwazi ukumelana nomfutho ophezulu.

Uma ngikhuluma nabaphathi bokuthenga abanjengoBudi, umbuzo othi “I-PE 80 vs. I-PE 100"Kuhlala kuvela umehluko omncane, kodwa lelo nani liyisihluthulelo sokusebenza kwezinto ezibonakalayo. Limelela amashumi eminyaka obunjiniyela bamakhemikhali kanye nokusungula izinto ezintsha. Ukuqonda lokhu kuhlukaniswa okulula kuyisinyathelo sokuqala sokukhetha ipayipi elithembekile nelingabizi kakhulu kunoma yimuphi umsebenzi. Ake sihlukanise ukuthi lezo zinombolo zisho ukuthini ngempela ebhizinisini lakho.

Uyini umehluko phakathi kwe-PE 80 ne-PE 100?

Uqhathanisa izingcaphuno bese ubona amapayipi e-PE 80 kanye ne-PE 100. I-PE 80 ishibhile, kodwa ingabe iqine ngokwanele? Ukukhetha ngokusekelwe entengo kuphela kuyingozi enkulu.

I-PE 100 ine-Minimum Required Strength (MRS) engu-10.0 MPa, kanti i-PE 80′s ingu-8.0 MPa. Lokhu kwenza i-PE 100 ibe namandla, okuvumela ukuthi ikwazi ukusingatha ingcindezi ephezulu. Ngesilinganiso esifanayo sengcindezi, ipayipi le-PE 100 lingaba nodonga oluncane, okusindisa izinto kanye nesisindo.

Inombolo egameni yinto ebaluleke kakhulu okufanele uyiqonde. Akuyona nje igama lokumaketha; kuyisigaba sesayensi esisekelwe emandleni esikhathi eside.Amandla Adingekayo Aphansi (MRS)kunqunywa ngokuhlola izinto ezingaphansi kwengcindezi isikhathi eside kakhulu ukuze kubikezelwe ukusebenza kwazo eminyakeni engaphezu kwengu-50.

• I-PE 80:Ine-MRS engu-8.0 MPa. Lokhu bekuyindinganiso iminyaka eminingi futhi kuseyithuluzi elihle.
• I-PE 100:Ine-MRS engu-10.0 MPa. Lokhu kungukukhuphuka okungu-25% kwamandla amancane kune-PE 80.

Lokhu kuqina okwengeziwe kukunikeza izinzuzo ezimbili ezinkulu. Okokuqala, ungasebenzisa ipayipi le-PE 100 ukusingatha ukucindezela okuphezulu kunepayipi le-PE 80 elinobukhulu obufanayo bodonga. Okwesibili, futhi ngokuvamile, ungasebenzisa ipayipi le-PE 100 elinodonga oluncane ukuze ufinyelele isilinganiso esifanayo sokucindezela. Udonga oluncane lusho izinto ezincane zokusetshenziswa, okwenza ipayipi libe lula futhi ngokuvamile lingabizi kakhulu. Liphinde linikeze ipayipi ububanzi obukhulu bangaphakathi, okuthuthukisa izici zokugeleza.

Kusho ukuthini ukuthi i-PE 100 grade isho ukuthini ngepayipi le-HDPE?

Ubona “i-PE 100 Grade” ephepheni lemininingwane. Kulula ukungayinaki njengelinye igama lobuchwepheshe, kodwa leli banga lithinta ngqo ukusebenza kwephayiphi kanye nokuthembeka kwesikhathi eside.

Ipayipi le-HDPE “le-PE 100 grade” liqinisekisiwe ukuthi lenziwe nge-resin ye-PE 100 esebenza kahle kakhulu. Lokhu kuqinisekisa amandla ayo aphezulu (10.0 MPa MRS), isilinganiso esihle kakhulu sokucindezela, kanye nokumelana okuphezulu kokukhula okuncishisiwe kokuqhekeka, okuqinisekisa impilo yenkonzo ende.

Uma ubona “Ibanga le-PE 100"," kuyisiqinisekiso sekhwalithi nokusebenza kahle. Kusho ukuthi ipayipi alenziwanga nje nganoma iyiphi ipulasitiki ejwayelekile; lenziwe nge-resin eklanywe ngokukhethekile futhi yahlolwa ukuze ihlangabezane nezinga eliphezulu. Ngaphandle kwamandla aphezulu, leli banga linikeza ezinye izinzuzo ezibalulekile. Enye yezinto ezibaluleke kakhulu ukumelana kwayo okuphezulu ne-Ukukhula Okusheshayo Kokuqhekeka (i-SCG)Ngesikhathi sokufakwa, amapayipi angathola imihuzuko emincane noma amaqhubu. Ezintweni ezisezingeni eliphansi, lawa maphutha amancane angakhula kancane kancane abe yimfantu enkulu eminyakeni eminingi yokujikeleza kwengcindezi, ekugcineni abangele ukuthi ipayipi lingasebenzi. I-PE 100 yenzelwe ukumelana nalokhu, okwenza iqine kakhulu futhi ithethelele izimo zokufakwa zangempela. Kuyisinqumo esifanele samapayipi azogqitshwa futhi adinga ukuhlala amashumi eminyaka ngaphandle kwezinkinga.

Kungani i-modulus yokuqina kwe-PE 100 ibalulekile?

Ufunda "i-modulus of elasticity" ekhasini ledatha bese amehlo akho ecwebezela. Leli gama lobuchwepheshe libonakala lingabalulekile, kodwa empeleni lichaza enye yezinzuzo ezinkulu ezingokoqobo zale nto.

I-modulus yokunwebeka ilinganisa ukuqina. I-PE 100 ine-modulus ephansi, okwenza iguquguquke kakhulu. Lokhu kuvumela ipayipi ukuthi ligobe eduze kwezithiyo, linikezwe ngama-coil amade, futhi lisetshenziswe ezindleleni zokufaka ezingenamisele, okunciphisa kakhulu izindleko zokufaka.

Kubalulekile ukungadidanisi amandla nokuqina. Izinto ezifana nengilazi ziqinile kakhulu, kodwa aziqinile uma zishayisana ngoba ziyaphuka. I-PE 100 iqinile kakhulu futhi iguquguquka kakhulu. Lokhu kuguquguquka kuyinzuzo enkulu ngesikhathi sokufakwa. Kuma-diameter amancane, singahlinzeka ngepayipi ngama-coil amade angamamitha ayi-100 noma ngaphezulu. Lokhu kusho ukuthi kudingeka amalunga ambalwa, okusindisa isikhathi esiningi futhi kuqede amaphuzu angaba buthaka. Kuma-diameter amakhulu, lokhu kuguquguquka kuvumela ipayipi ukuthi lisetshenziswe ezindleleni zokufaka zesimanje ezifanaUkubhoboza Okuqondisiwe Okuvundlile (i-HDD)Lokhu kuvumela abafaki ukuthi badonse ipayipi ngaphansi komhlaba ngaphandle kokumba umsele omude, ophazamisayo. Lokhu kulungele ukuwela imifula, imigwaqo, noma izindawo ezizwela imvelo. Ezweni elifana ne-Indonesia elinendawo ehlukahlukene, lokhu kuguquguquka kungonga imali eningi ezindlekweni zokufaka uma kuqhathaniswa namapayipi aqinile.

Ingabe i-PE 100 ingcono kune-PVC?

I-PVC iyinto evame kakhulu ukusetshenziswa kumapayipi, futhi cishe uyayazi kakhulu. Ivame ukuba nezindleko zokuqala eziphansi, ngakho kungani kufanele ushintshele ku-PE 100?

I-PE 100 ngokuvamile ingcono kakhulu kuma-mains agqitshwe phansi. Izinzuzo zayo ezibalulekile kune-PVC ukuguquguquka kwayo, ukumelana okuphezulu kokushayisana, kanye namajoyinti ahlanganisiwe angavuzi. Amajoyinti e-PVC afakwe i-solvent noma afakwe igesi avame ukuba yiphuzu elibuthakathaka kakhulu ohlelweni, inkinga eqedwa ngokuphelele yi-fusion welding.

Nakuba zombili izinto zinhle, zenzelwe amandla ahlukene. Inzuzo enkulu ye-PE 100 yindlela yokuhlanganisa.

Amajoyinti ayizihluthulelo. Uma ufudumeza i-fuse yepayipi le-PE 100, ijoyinti iba yingcezu eyodwa, eqhubekayo yepulasitiki. Ayikwazi ukuvuza. Nge-PVC, usebenzisa i-weld ye-solvent yamakhemikhali noma i-gasket yerabha. La majoyinti cishe ayindawo yokuqala lapho ukuvuza kuzokwenzeka khona esikhathini eside. Kunoma yiliphi ipayipi elifihliwe lapho ukulungiswa kungaba kubi kakhulu futhi kunzima, ijoyinti eliqinisekisiwe elingavuzi le-PE 100 lenza kube utshalomali oluhle kakhulu lwesikhathi eside.

Isiphetho

I-PE 100 ingaphezu nje kwenombolo. Amandla ayo aphezulu, ukuguquguquka, kanye namajoyinti ahlanganisiwe angavuzi kwenza kube ukukhetha kwesimanje nokwethembekile kwanoma yimuphi umsebenzi obalulekile wokufaka amapayipi isikhathi eside.
