Ujonge iinkcukacha zepayipi kwaye ubona iikhowudi ezifana ne-PE80 kunye ne-PE100. Le ntetho yobugcisa iyadida, kwaye ukukhetha uhlobo olungalunganga kunokubeka emngciphekweni ingqibelelo yexesha elide yeprojekthi yakho.

I-PE100 ithetha ukuba umbhobho wenziwe ngesizukulwana samva nje seHigh-Density Polyethylene (HDPE). I-“100″ imele iMinimum Required Strength (MRS) ye-10.0 MPa. Oku kuyenza ibe yinto eqinileyo nehlala ixesha elide evumela iindonga zepayipi ezincinci ngeqondo elifanayo loxinzelelo.

Xa ndithetha nabaphathi bokuthenga abanjengoBudi, la manqaku ezinto ezibonakalayo ayinto exhaphakileyo. Kulula ukuwabona nje ngamanani, kodwa i-“PE100” imele amashumi eminyaka okuqhubela phambili kwesayensi yezinto ezibonakalayo. Lithemba lamandla, ukuthembeka, kunye nokusebenza kwexesha elide. Ukuqonda ukuba le khowudi ilula ithetha ukuthini ngundoqo ekwenzeni isigqibo sokuthenga esihlakaniphileyo esiqinisekisa impumelelo yeenkqubo zakho zolawulo lwamanzi kwiminyaka ezayo. Makhe sihlalutye ukuba eli nqanaba lithetha ukuthini ngokwenene kwiiprojekthi zakho.

Ngaba i-PE100 ingcono kune-PVC?

I-PVC yinto eqhelekileyo kwaye idla ngokuba nexabiso eliphantsi kwangaphambili. Oku kwenza kube lula ukuyikhetha, kodwa ukuqina kwayo kunye nendlela yokudibanisa kunokukhokelela kwiingxaki zexesha elizayo kunye neendleko eziphezulu xa iyonke.

Kwimithombo yamanzi egqunyiweyo, i-PE100 ingcono ngokubanzi. Iyakwazi ukuguquguquka, ukumelana nokuchaphazeleka okuphezulu, kunyeamalungu adibeneyo angavuziyozibonelela ngokuthembeka okuphezulu kwexesha elide. Amalungu e-PVC afakwe isinyibilikisi okanye afakwe igesi adla ngokuba yeyona ndawo ibuthathaka kwinkqubo, ingxaki leyoukuwelda kwe-fusionisusa ngokupheleleyo.

Nangona zombini ezi zinto zilungile kwizicelo ezithile, umahluko wazo osisiseko uyacaca kwiimeko ezinzima. Eyona nzuzo inkulu ye-PE100 yindlela yokudibanisa. Xa ufudumeza i-fuse yombhobho we-HDPE, ijoyinti iba yiplastiki enye, eqinileyo, eqinileyo njengombhobho ngokwawo. Ayinakuvuza. Ijoyinti ze-PVC, ezixhomekeke kwisamente ye-solvent okanye i-raber gaskets, zizisa indawo enokwenzeka yokusilela. Ngokuhamba kwexesha, ukuhamba komhlaba kunye notshintsho loxinzelelo lunokuphazamisa la malungu. Ukuguquguquka kwe-PE100 kukwavumela ukufakwa ngaphandle kwemisele, okunokunciphisa kakhulu ixesha lokwakha kunye neendleko, inzuzo enkulu kwiindawo ezixineneyo zasezidolophini. I-PVC, ekubeni iqinile, ifuna ukumba umsele ovulekileyo wendabuko, okuphazamisayo kwaye kubiza kakhulu.

Yintoni umahluko phakathi kwe-PE 80 kunye ne-PE100?

Ubona iikowuteshini ezimbini, enye yepayipi ye-PE80 kunye nenye ye-PE100. Amanani abonakala esondelelene, kodwa ukukhetha umgangatho ophantsi ukuze wonge imali encinci kunokuthetha ukufaka ipayipi ebuthathaka.

Eli nani libhekisa kwiMinimum Required Strength (MRS) emva kweminyaka engama-50. I-PE100 ine-MRS eyi-10.0 MPa, ngelixa i-PE80 iyi-8.0 MPa. Oku kunyuka kwamandla ngama-25% kuvumela iipayipi ze-PE100 ukuba zibe neendonga ezincinci zomlinganiselo ofanayo woxinzelelo.

IAmandla Aphantsi Afunekayo (MRS)lixabiso elichaza amandla exesha elide ezinto. Izazinzulu ziyichonga ngokubeka umbhobho phantsi koxinzelelo kunye nokulinganisa ukuba kuthatha ixesha elingakanani ukusilela, emva koko zisebenzisa loo datha ukuqikelela amandla ayo kwiminyaka engama-50 yobomi benkonzo. Okukhona i-MRS iphezulu, kokukhona inamandla le nto.

Le nzuzo yamandla angama-25% ye-PE100 kune-PE80 ikunika iingenelo ezimbini ezibalulekileyo. Okokuqala, kumbhobho onobukhulu obufanayo, i-PE100 inokumelana noxinzelelo oluphezulu. Okwesibini, kwaye okubaluleke ngakumbi ukuze wonge imali, ungasebenzisa i-Umbhobho we-PE100 onodonga oluncinciukuze kufunyanwe uxinzelelo olufanayo nombhobho we-PE80 otyebileyo. Udonga oluncinci luthetha ukuba kusetyenziswa izinto ezincinci, nto leyo eyenza umbhobho ube lula kwaye ungabizi kakhulu. Umbhobho olula ungabizi kakhulu ukuwuthutha kwaye kulula ukuwuphatha kwindawo. Udonga oluncinci lukwadala ububanzi obukhulu bangaphakathi, nto leyo ephucula ukuhamba kwamanzi kwaye inciphise iindleko zokumpompa kulo lonke ixesha lenkqubo.

Yeyiphi engcono, i-HDPE okanye i-PE?

Amagama athi PE kunye ne HDPE adla ngokusetyenziswa kwincoko enye. Oku kunokukubhida, kukwenze ucinge ukuba uthelekisa izinto ezimbini ezahlukeneyo ngokupheleleyo ngoxa ungenjalo.

Lo ngumbuzo onzima, njengoko i-HDPE (i-High-Density Polyethylene) iyinto ekhethekileyo.uhloboye-PE (iPolyethylene). I-PE ligama losapho olubanzi. Kwimibhobho yoxinzelelo lwamanzi negesi, i-HDPE lukhetho olufanelekileyo nolugqwesileyo ngenxa yamandla ayo nokuqina kwayo.

Cinga nge-“Polyethylene” (PE) njengegama losapho lweqela lonke leeplastiki. Kule ntsapho, kukho iintlobo ezahlukeneyo ngokusekelwe kubuninzi bazo beemolekyuli, nto leyo echaza iimpawu zazo zomzimba.

• I-PE (iPolyethylene):Udidi lulonke.
• I-LDPE (iPolyethylene eNcinci):Iguquguquka kakhulu, isetyenziselwa izinto ezifana neengxowa zeplastiki kunye neefilimu. Ayifanelekanga kwiipayipi zoxinzelelo.
• I-HDPE (iPolyethylene enoxinano oluphezulu):Iqine kakhulu, iqinile ngakumbi, kwaye iqinile ngakumbi. Le yeyona nto iqhelekileyo kwimibhobho yoxinzelelo esetyenziswa ekunikezelweni kwamanzi, ekusasazweni kwegesi, nakwiindawo zoshishino.

Ngoko ke, xa sithetha ngepayipi ye-PE kwimeko yolawulo lwamanzi, phantse sithetha ngepayipi ye-HDPE rhoqo. Amanqanaba esiwaxubushileyo ngaphambili, i-PE80 kunye ne-PE100, ziindlela ezithile zokusebenza kwe-resin ye-HDPE. Ngoko ke, umbuzo awungowokuba “i-HDPE okanye i-PE?” kodwa ngulo, “Ngowuphi umgangatho we-HDPE ofanelekileyo kwiprojekthi yam?”. Kuyo nayiphi na indawo entsha yokufaka, i-PE100 grade HDPE yeyona ndlela ilungileyo.

Ngaba ungayishicilela i-PE80 kwi-PE100?

Udinga ukulungisa umgca wamanzi omdala owenziwe nge-PE80. Isitokhwe sakho esitsha yi-PE100 yonke. Ukuwelda okungaphumeleli phakathi kwezinto ezimbini kunokubangela ukuphazamiseka okukhulu kwenkonzo.

Ewe, ungayishibiliza i-PE80 ngqo kwi-PE100. Ngenxa yokuba zombini zivela kusapho lwe-polyethylene, iiplastiki zazo ziya kudibana. Nangona kunjalo, kufuneka usebenzise iiparameter zokushibiliza kwi-PE80 yodidi oluphantsi, kwaye ijoyinti iya kuba namandla kuphela njengejoyinti ye-PE80.

Lo ngumbuzo obaluleke kakhulu kumsebenzi wolondolozo nokulungisa. Ukukwazi ukujoyina amanqanaba ahlukeneyo yinzuzo enkulu ye-HDPE. Ngenxa yokuba zombini i-PE80 kunye ne-PE100 zenziwe nge-polymer efanayo, izakhiwo zazo ze-molecular ziyahambelana kwaye ziya kudibana ngexesha lokudityaniswa kobushushu ukudala umanyano oluqinileyo noluhlala luhleli.

Nangona kunjalo, kukho umthetho omnye obalulekileyo ekufuneka uwulandele:Sebenzisa rhoqo iiparameter zokuwelda (ubushushu, ixesha, kunye noxinzelelo) ezichazwe kwizinto ezikumgangatho ophantsi.I-PE80 kunye ne-PE100 zinokuba neendlela zokunyibilika ezahlukeneyo kancinci, kwaye ukusebenzisa useto lwe-PE100 kunokubangela ubushushu obugqithisileyo okanye ukonakalisa isiphelo sepayipi ye-PE80, nto leyo ebangela ukuba i-joint ibe buthathaka. Into yesibini ekufuneka uyikhumbule kukuba inkqubo inamandla kuphela xa iqhagamshelene nobuthathaka bayo. I-joint edibeneyo kunye necandelo lonke lepayipi ziya kuba nomlinganiselo woxinzelelo kunye neempawu zokusebenza zepayipi ye-PE80, hayi i-PE100. Nangona kwiiprojekthi ezintsha sisoloko sicebisa i-PE100, oku kuhambelana kulungele ukwandisa okanye ukulungisa iziseko zophuhliso ezindala.

Isiphelo

PE100ayisiyo khowudi nje kuphela; yinqanaba le-HDPE esebenza kakhulu. Amandla ayo aphezulu kunye nokuthembeka kwayo kwenza ibe ngumgangatho wanamhlanje wokwakha imibhobho yamanzi ekhuselekileyo nehlala ixesha elide.
