Ukukhetha izinto ezifanelekileyo zombhobho kubalulekile kwimpumelelo yeprojekthi yexesha elide. Uxhalabile kukuba amagama anzima anje nge-“PE100” afihla iingozi.I-PE100 yindlela eqhelekileyo yanamhlanje yeepayipi zeplastiki ezinamandla aphezulu.

Umbhobho we-PE100 ngumbhobho woxinzelelo owenziwe nge-High-Density Polyethylene (HDPE) yomgangatho ophezulu. I-“100″ ibonisa amandla ayo aphantsi afunekayo (MRS) aqinisekisiweyo e-10 MPa, okuqinisekisa ukukwazi kwayo ukusingatha uxinzelelo oluphezulu kangangeminyaka engaphezu kwama-50, nto leyo eyenza ukuba ibe yeyona ifanelekileyo kwiziseko ezibalulekileyo.

Njengomvelisi weenkqubo zemibhobho kangangeminyaka ephantse ibe ngamashumi amabini, ndiye ndakha ishishini lam ngomgaqo omnye: ukuthembeka kuqala ngezinto eziluhlaza. I-PE100 ayilogama nje elingacwangciswanga; ngumgangatho wamazwe ngamazwe esixhomekeke kuwo thina kunye nabathengi bethu. Kwiingcali ezifana no-Arief, umphathi omkhulu wokuthenga e-Indonesia, esi siqinisekiso sisiqinisekiso. Sithetha ukuba umbhobho awufakela inkqubo yamanzi kamasipala unamandla aqinisiweyo okuhlala izizukulwana ngezizukulwana. Makhe sijonge nzulu ukuba lo mgangatho uthetha ukuthini kwaye kutheni ubaluleke kangaka kwiiprojekthi zakho.

Ngaba i-HDPE iyafana ne-PE100?

Uyabona i-HDPE kunye ne-PE100 zisetyenziswa kwiinkcukacha, kwaye akucaci ukuba yintoni umahluko. Olu bhideko lwenza kube nzima ukuthelekisa izinto.I-PE100 yinguqulelo ethile, ekumgangatho ophezulu ye-HDPE.

Hayi, azifani ncam. Zonke ii-PE100 ziyi-HDPE, kodwa ayizizo zonke ii-HDPE ezihlangabezana nomgangatho we-PE100. I-PE100 ludidi oluthile lwe-High-Density Polyethylene oluqinisekisiweyo ukuba lunamandla aphezulu kunye nokumelana nokuqhekeka koxinzelelo kunamanqanaba amadala e-HDPE.

Cinga nge-"HDPE" njengegama losapho olukhulu nolwahlukeneyo. Ngaphakathi kolu sapho, kukho izizukulwana ezahlukeneyo, ngasinye sinamandla angcono kunesokugqibela. Iipayipi zoxinzelelo zokuqala zenziwa ngamabakala afana ne-PE63. Emva koko iteknoloji yaphucuka, saza saphuhlisa i-PE80. Namhlanje, i-PE100 ngumgangatho wanamhlanje, osebenza kakuhle. Inani elisegameni likuxelela amandla ayo exesha elide. Ngoko ke, nangona ipayipi inokwenziwa nge-resin ye-HDPE eqhelekileyo, kuphelaI-resin eqinisekisiweyo yi-PE100iqinisekisiwe ukuba iya kufikelela kuloo mlinganiselo uphezulu. Xa senza imibhobho yoxinzelelo kwiziko lethu, sisebenzisa kuphela i-virgin PE100 resin. Eli linqanaba elibalulekileyo lokulawula umgangatho. Iqinisekisa ukuba yonke imitha yombhobho inokusebenza okuqikelelweyo, okuqinisekisiweyo okufunwa yiprojekthi yeziseko zophuhliso. Isusa naluphi na uqikelelo malunga namandla esixhobo kunye nobude baso.

Ukuthelekisa i-General HDPE ne-Certified PE100

Yintoni i-PE100 yezinto eziphathekayo?

Uva ngeendidi ezahlukeneyo zezinto zokwakha, kodwa i-“PE100” isenokubonakala ngathi linani. Oku kunokukwenza ungayinaki eyona nzuzo yayo ibalulekileyo.Ibanga lithembisa ngokuthe ngqo amandla exesha elide.

Uhlobo lwezinto ezibonakalayo i-PE100 luhlelo lwamazwe ngamazwe lwe-resin ye-HDPE olubonisa amandla amancinci afunekayo (MRS) e-10 Megapascals (MPa). Olu luhlu luqinisekisa amandla ezinto ezibonakalayo okumelana noxinzelelo lwangaphakathi kwiminyaka engama-50 yobomi bokusebenza ngaphandle kokusilela.

I-“100″ yeyona nxalenye ibalulekileyo yegama. Ivela kumlinganiselo we-10.0 MPa. Olu lwazi lobunjineli luvumela abayili ukuba babale umthamo woxinzelelo lombhobho ngokuzithemba okukhulu. Oku kunenzuzo esebenzisekayo kakhulu abaphathi bokuthenga abanemvelaphi yobunjineli abayibona ngokukhawuleza: ichaphazela ubukhulu bodonga lombhobho. Ngenxa yokuba i-PE100 inamandla kuneeklasi ezindala ezifana ne-PE80, inokusingatha uxinzelelo olufanayo ngodonga oluncinci. Silinganisa oku nge-Standard Dimension Ratio (SDR), eliyi-ratio yobubanzi bombhobho nobukhulu bodonga lwayo. Kwiklasi yoxinzelelo oluthile, umbhobho we-PE100 uya kuba ne-SDR ephezulu (udonga oluncinci) kunembhobho we-PE80. Oku kuthetha ukuba kusetyenziswa izinto ezincinci, nto leyo eyenza umbhobho ube lula, ungabizi kakhulu, kwaye kube lula ukuwuphatha nokuyifaka. Kukwakhokelela kwimbobo enkulu yangaphakathi, nto leyo ephucula umthamo wokuhamba kwamanzi.

Inzuzo ye-PE100: Iindonga ezibhityileyo, Ukuhamba kakuhle

Zingakanani uxinano lwezinto ze-PE100?

Igama elithi “High-Density” likwigama, kodwa oko kunokuvakala ngathi akucacanga. Ngaphandle kokuqonda ukuba kuthetha ukuthini, awunakuyiqonda into yokuba kutheni le nto isetyenziswa kakuhle kangaka.Ubuninzi bomthombo wamandla ayo.

I-PE100 yiPolyethylene enobuninzi obuphezulu, kwaye ubuninzi bezinto zayo buhlala buphakathi kwe-0.95 ukuya kwi-0.97 grams nge-cubic centimeter (g/cm³). Olu buninzi buphezulu yilo lunika izinto ukuqina kwazo, amandla okutsalwa, kunye nokumelana okuhle kweekhemikhali.

Ngokwembono yokuvelisa, uxinano yinto yonke. Sidala olu xinano luphezulu kwinqanaba leemolekyuli. I-Polyethylene yenziwe ngeetsheyini ezinde zeemolekyuli. Kwi-High-Density Polyethylene, ezi tsheyini zithe tye kakhulu kwaye azinamasebe amaninzi. Oku kuzivumela ukuba zipakishwe ndawonye ngokuqinileyo kwaye zenze isakhiwo sekristale. Olu xinano luqinileyo luthetha ukuthini "uxinano oluphezulu". Yiyo loo nto izinto ziqinile kwaye ziqinile. Ngokwahlukileyo koko, i-Low-Density Polyethylene (LDPE) ineetsheyini ezinamasebe amaninzi. La masebe athintela iitsheyini ukuba zingapakishwanga ngokusondeleyo, nto leyo ebangela ukuba izinto ezinoxinano oluphantsi zithambile kwaye ziguquguquke, njengengxowa yeplastiki. Kwipayipi efuna ukubamba uxinzelelo phantsi komhlaba amashumi eminyaka, udinga amandla avela kuphela kwisakhiwo esixineneyo nesixineneyo. Esi sisizathu esibalulekileyo sokuba i-PE100 ibe lukhetho oluphezulu lweziseko zophuhliso.

Ubuninzi kunye nefuthe labo kwiipropati

Zithini iingxaki zombhobho we-PE?

Akukho zixhobo zifanelekileyo kuyo yonke imeko. Ukungawunaki umda wepayipi ye-PE kunokukhokelela kwiimpazamo zoyilo okanye zokufakela ezibizayo. Ukuqonda ubuthathaka bayo kukuvumela ukuba uyisebenzise ngokuchanekileyo nangokufanelekileyo.

Eyona ngxaki iphambili yombhobho we-PE kukuba sesichengeni sayo kwimitha ye-UV ngaphandle kokhuseleko, umda wobushushu obuphantsi bokusebenza kunentsimbi, kunye nesantya esiphezulu sokwandiswa kobushushu. Ukufakelwa ngokufanelekileyo kufuna izixhobo ezikhethekileyo zokudibanisa kunye nabaqhubi abaqeqeshiweyo.

Njengomvelisi, ndikholelwa ekubeni ndinyaniseke malunga nemida yemveliso. Yakha ukuthembana kwaye ikhokelela kwiiprojekthi ezingcono. Okokuqala, umbhobho we-PE usengoziniUkonakala kwe-UV ngenxa yelanga. Sisombulula oku ngokongeza malunga ne-2–3% yekhabhoni emnyama kwizinto eziluhlaza. Yingakho imibhobho yoxinzelelo phantse isoloko imnyama; umnyama wekhabhoni usebenza njengesiqinisi se-UV esinamandla. Okwesibini, inomlinganiselo ophantsi wobushushu kunemibhobho yesinyithi. Akufanele isetyenziswe kumanzi ashushu angaphezulu kwama-60°C (140°F). Okwesithathu, iyakhula kwaye inciphe ngotshintsho lobushushu ngaphezu kwentsimbi okanye isinyithi esithambileyo. Kufakelo olungaphezulu komhlaba, oku kufuneka kulawulwe ngee-expansion loops okanye ezinye izinto zoyilo. Kwimibhobho egqunywe phantsi komhlaba, oku akuyongxaki ingako. Okokugqibela, ukujoyina i-HDPE kufuna iingcali eziqeqeshiweyo kunye nezixhobo zokudibanisa. Nangona oku kubonakala ngathi kukubi, kukwanamandla ayo amakhulu, njengoko kuqinisekisa ijoyinti egqibeleleyo, engavuziyo ngalo lonke ixesha.

Ukulawula Imida ye-PE Pipe

Isiphelo

Umbhobho we-PE100 ngowona mgangatho uphezulu we-HDPE, ochazwa ngamandla awo kunye nokuqina kwawo. Ukuqonda iimpawu zawo kunye nokulawula imida yawo embalwa kukuvumela ukuba wakhe iziseko ezithembekileyo nezihlala ixesha elide.

Ukuba ujonge iipayipi ze-HDPE PE100 ezithembekileyo kunye nezixhobo zeprojekthi zakho, zive ukhululekile ukuzisebenzisa.Qhagamshelana nathingeenkcukacha zemveliso kunye nenkxaso yobugcisa.
