Ukukhetha izinto ezifanele zamapayipi kubalulekile empumelelweni yephrojekthi yesikhathi eside. Ukhathazekile ngokuthi amagama ayinkimbinkimbi anjengelithi “PE100” afihla izingozi.I-PE100 imane iyindinganiso yesimanje yamapayipi epulasitiki anamandla aphezulu.

Ipayipi le-PE100 liyipayipi lokucindezela elenziwe nge-High-Density Polyethylene (HDPE) esezingeni eliphezulu. I-“100″ isho amandla ayo amancane adingekayo (MRS) aqinisekisiwe angu-10 MPa, okuqinisekisa ikhono layo lokusingatha ukucindezela okuphezulu iminyaka engaphezu kwengu-50, okwenza libe yindawo ekahle kakhulu yengqalasizinda ebalulekile.

Njengomkhiqizi wezinhlelo zamapayipi cishe iminyaka engamashumi amabili, ngakhe ibhizinisi lami ngesimiso esisodwa: ukuthembeka kuqala ngezinto zokusetshenziswa. I-PE100 akuyona nje igama elingahleliwe; iyindinganiso yamazwe ngamazwe esithembele kuyo thina namakhasimende ethu. Kwabochwepheshe abanjengo-Arief, umphathi omkhulu wokuthenga e-Indonesia, lesi sitifiketi siyisiqinisekiso. Kusho ukuthi ipayipi alifakayo ohlelweni lwamanzi lukamasipala linamandla aklanywe ngendlela yokuthi lihlale izizukulwane ngezizukulwane. Ake sibheke ngokujulile ukuthi lisho ukuthini leli ndinganiso nokuthi kungani libaluleke kangaka kumaphrojekthi akho.

Ingabe i-HDPE iyafana ne-PE100?

Ubona i-HDPE ne-PE100 zisetshenziswa ezicacisweni, futhi akucaci ukuthi umehluko uyini. Lokhu kudideka kwenza kube nzima ukuqhathanisa izinto.I-PE100 inguqulo ethile, esezingeni eliphezulu ye-HDPE.

Cha, azifani ncamashi. Zonke i-PE100 ziyi-HDPE, kodwa akuwona wonke ama-HDPE ahlangabezana nezindinganiso ze-PE100. I-PE100 uhlobo oluthile lwe-High-Density Polyethylene oluqinisekisiwe ukuthi lunamandla aphezulu kanye nokumelana nokuqhekeka kokucindezeleka kunamazinga amadala e-HDPE.

Cabanga nge-“HDPE” njengegama lomndeni omkhulu nohlukahlukene. Ngaphakathi kwalo mndeni, kunezizukulwane ezahlukene, ngasinye sinamakhono angcono kunezokugcina. Amapayipi okuqala okucindezela enziwa ngamamaki afana ne-PE63. Ubuchwepheshe bathuthuka, futhi sathuthukisa i-PE80. Namuhla, i-PE100 iyindinganiso yesimanje, esebenza kahle kakhulu. Inombolo esegameni ikutshela amandla ayo esikhathi eside. Ngakho-ke, yize ipayipi lingenziwa nge-resin ye-HDPE ejwayelekile, i-aI-resin eqinisekiswe yi-PE100kuqinisekisiwe ukuthi kuzohlangabezana naleyo ndlela yokulinganisa enamandla aphezulu. Uma sakha amapayipi okucindezela esikhungweni sethu, sisebenzisa kuphela i-virgin PE100 resin. Leli iphuzu elibalulekile lokulawula ikhwalithi. Liqinisekisa ukuthi yonke imitha yepayipi inokusebenza okubikezelwayo, okuqinisekisiwe okudingwa amaphrojekthi engqalasizinda. Lisusa noma yikuphi ukuqagela mayelana namandla ezinto kanye nobude besikhathi.

Ukuqhathanisa i-General HDPE ne-Certified PE100

Iyini i-PE100 yezinto ezibonakalayo?

Uzwa ngamamaki ahlukene ezinto ezibonakalayo, kodwa i-“PE100” ingase ibonakale njengenombolo. Lokhu kungakwenza ungayinaki inzuzo yayo ebaluleke kakhulu.Ibanga liyisithembiso esiqondile samandla esikhathi eside.

Ibanga lezinto ezibonakalayo i-PE100 liyisigaba samazwe ngamazwe se-resin ye-HDPE esibonisa Amandla Aphansi Adingekayo (i-MRS) angu-10 Megapascals (i-MPa). Leli banga liqinisekisa ikhono lezinto ezibonakalayo lokumelana nengcindezi yangaphakathi phakathi neminyaka engu-50 yokuphila ngaphandle kokwehluleka.

I-“100″ yingxenye ebaluleke kakhulu yegama. Ivela esilinganisweni se-10.0 MPa. Lokhu kuchazwa kobunjiniyela kuvumela abaklami ukubala umthamo wokucindezela wepayipi ngezinga eliphezulu lokuzethemba. Lokhu kunenzuzo ewusizo kakhulu abaphathi bokuthenga abanesizinda sobunjiniyela abayibona ngokushesha: kuthinta ubukhulu bodonga lwepayipi. Ngenxa yokuthi i-PE100 inamandla kunamabanga amadala njenge-PE80, ingaphatha ingcindezi efanayo ngodonga oluncane. Silinganisa lokhu nge-Standard Dimension Ratio (SDR), okuyisilinganiso sobubanzi bepayipi nobukhulu bodonga lwayo. Kwisigaba esithile sokucindezela, ipayipi le-PE100 lizoba ne-SDR ephezulu (udonga oluncane) kunepayipi le-PE80. Lokhu kusho ukuthi kusetshenziswa izinto ezincane zokusetshenziswa, okwenza ipayipi libe lula, lingabizi kakhulu, futhi kube lula ukuphatha nokulifaka. Kuphinde kuphumele ebhoreni elikhulu langaphakathi, elithuthukisa umthamo wokugeleza.

Inzuzo ye-PE100: Izindonga Ezincane, Ukugeleza Okungcono

Kungakanani ubuningi bezinto ze-PE100?

Igama elithi “High-Density” lisegameni, kodwa lokho kungazwakala kungaqondakali. Ngaphandle kokuqonda ukuthi kusho ukuthini, awukwazi ukuqonda ukuthi kungani izinto zisebenza kahle kangaka.Ubuningi buwumthombo wamandla ayo.

I-PE100 iyi-High-Density Polyethylene, futhi ubuningi bezinto zayo buvame ukuba phakathi kwamagremu angu-0.95 kuya ku-0.97 ngesentimitha ngalinye le-cubic (g/cm³). Lokhu buningi obukhulu yikona okunikeza izinto ukuqina kwazo, amandla okuthamba, kanye nokumelana okuhle kwamakhemikhali.

Ngokombono wokukhiqiza, ubuningi buyikho konke. Sakha lokhu buningi obuphezulu ezingeni lama-molecule. I-Polyethylene yenziwe ngamaketanga amade ama-molecule. Ku-High-Density Polyethylene, la maketanga aqondile kakhulu futhi anamagatsha amancane kakhulu. Lokhu kuwavumela ukuthi ahlanganiswe ndawonye ngokuqinile futhi akhe isakhiwo sekristalu. Lokhu kuhlanganiswa okuqinile yilokho okushiwo "ubuningi obukhulu". Yingakho izinto ziqinile futhi ziqinile. Ngokuphambene nalokho, i-Low-Density Polyethylene (LDPE) inamaketanga anamagatsha amaningi. Lawa magatsha avimbela amaketanga ukuthi ahlanganiswe eduze, okuholela ezintweni eziphansi zobuningi ezithambile neziguquguqukayo, njengesikhwama sepulasitiki. Kumbhobho odinga ukubamba ingcindezi ngaphansi komhlaba amashumi eminyaka, udinga amandla avela kuphela kuleso sakhiwo esiqinile, sobuningi obukhulu. Lesi yisizathu esiyisisekelo sokuthi kungani i-PE100 iyisinqumo esingcono kakhulu sengqalasizinda.

Ubuningi kanye Nomphumela Wabo Ezimpahleni

Yiziphi izinkinga zepayipi le-PE?

Akukho mpahla efanelekile kuzo zonke izimo. Ukungazinaki imikhawulo yepayipi le-PE kungaholela emaphutheni okuklama noma okufakwayo abizayo. Ukuqonda ubuthakathaka balo kukuvumela ukuthi ulisebenzise ngendlela efanele nangempumelelo.

Izinkinga eziyinhloko zepayipi le-PE ukuthi lisengozini yokushiswa yimisebe ye-UV ngaphandle kokuvikelwa, umkhawulo wokushisa ophansi wokusebenza kunensimbi, kanye nesilinganiso esiphezulu sokwanda kokushisa. Ukufakwa kahle kudinga nemishini ekhethekile yokuhlanganisa kanye nabasebenzi abaqeqeshiwe.

Njengomkhiqizi, ngikholelwa ekuthembekeni mayelana nokulinganiselwa komkhiqizo. Kwakha ukwethembana futhi kuholela kumaphrojekthi angcono. Okokuqala, ipayipi le-PE lisengozini yokuthelelekaUkuwohloka kwe-UV okuvela elangeni. Sixazulula lokhu ngokungeza cishe u-2–3% wekhabhoni emnyama ezintweni ezingavuthiwe. Yingakho amapayipi okucindezela cishe eba mnyama njalo; umnyama wekhabhoni usebenza njengesiqinisi se-UV esinamandla. Okwesibili, unezinga lokushisa eliphansi kunemapayipi ensimbi. Akufanele isetshenziselwe ukusetshenziswa kwamanzi ashisayo ngaphezu kuka-60°C (140°F). Okwesithathu, iyakhula futhi inciphe ngokushintsha kwezinga lokushisa ngaphezu kwensimbi noma insimbi ethambile. Ekufakweni okungaphezulu komhlaba, lokhu kumele kuphathwe ngezihibe zokwandisa noma ezinye izinto ezicatshangelwayo zokuklama. Kumapayipi agqitshwe, lokhu akuyona inkinga enkulu. Okokugcina, ukujoyina i-HDPE kudinga ochwepheshe abaqeqeshiwe kanye nemishini yokuhlanganisa. Nakuba lokhu kubonakala kuyinkinga, futhi kungamandla ayo amakhulu, njengoba kuqinisekisa ijoyinti eliphelele, elingavuzi njalo.

Ukuphatha Imikhawulo Yepayipi Le-PE

Isiphetho

Ipayipi le-PE100 liyindinganiso ephezulu kakhulu ye-HDPE, echazwa amandla ayo nokuqina kwayo. Ukuqonda izakhiwo zayo nokuphatha imikhawulo yayo embalwa kukuvumela ukuthi wakhe ingqalasizinda ethembekile nehlala isikhathi eside.

Uma ufuna amapayipi e-HDPE PE100 athembekile kanye nokufakwa kwamaphrojekthi akho, zizwe ukhululekileXhumana nathiukuthola imininingwane yomkhiqizo kanye nokusekelwa kobuchwepheshe.
