Uzama ukukhetha izinto zombhobho ezifanelekileyo. Iikhowudi ezifana ne-PE 80 kunye ne-PE 100 ziyadida, kwaye ukwenza ukhetho olungalunganga kunokukhokelela ekusileleni kwenkqubo kunye nokulungiswa okubiza kakhulu.

I-PE 100 sisizukulwana samva nje seHigh-Density Polyethylene (HDPE). I-“100″ ithetha ukuba inamandla afunekayo (MRS) angama-10.0 MPa, nto leyo eyenza ibe namandla kunezixhobo ezindala. Oku kuvumela imibhobho eneendonga ezincinci ezisakwazi ukumelana noxinzelelo oluphezulu.

Xa ndithetha nabaphathi bokuthenga abanjengoBudi, umbuzo othi “I-PE 80 vs. I-PE 100"Ihlala ivela. Kubonakala ngathi ngumahluko omncinci, kodwa elo nani lisitshixo ekusebenzeni kwezinto. Limele amashumi eminyaka obunjineli beekhemikhali kunye nophuhliso. Ukuqonda olu hlobo lulula linyathelo lokuqala lokukhetha umbhobho othembekileyo nongabizi kakhulu kuyo nayiphi na iprojekthi. Masihlalutye oko kuthethwa ngala manani kwishishini lakho.

Yintoni umahluko phakathi kwe-PE 80 kunye ne-PE 100?

Uthelekisa iikowuteshini kwaye ubona iipayipi ze-PE 80 kunye ne-PE 100. I-PE 80 itshiphu, kodwa ingaba yomelele ngokwaneleyo? Ukukhetha ngokusekelwe kwixabiso lodwa kuyingozi enkulu.

I-PE 100 inoMgangatho oNcinci ofunekayo (MRS) we-10.0 MPa, ngelixa i-PE 80′s iyi-8.0 MPa. Oku kwenza i-PE 100 ibe namandla, nto leyo eyivumela ukuba ikwazi ukumelana noxinzelelo oluphezulu. Kwinqanaba elifanayo loxinzelelo, umbhobho we-PE 100 unokuba nodonga oluncinci, nto leyo egcina izinto kunye nobunzima.

Inombolo esegameni yeyona nto ibalulekileyo ekufuneka uyiqonde. Ayisiyonto yokuthengisa nje kuphela; luluhlu lwesayensi olusekelwe kumandla exesha elide.Amandla Aphantsi Afunekayo (MRS)ifunyanwa ngokuvavanya izinto eziphantsi koxinzelelo ixesha elide ukuze kuqikelelwe ukusebenza kwazo kwiminyaka engaphezu kwama-50.

• I-PE 80:Ine-MRS ye-8.0 MPa. Le yayiyimeko eqhelekileyo kangangeminyaka emininzi kwaye iseseyisixhobo esilungileyo.
• I-PE 100:Ine-MRS eyi-10.0 MPa. Oku kukunyuka kwe-25% kwamandla amancinci kune-PE 80.

La mandla ongezelelweyo akunika iingenelo ezimbini ezibalulekileyo. Okokuqala, ungasebenzisa umbhobho we-PE 100 ukusingatha uxinzelelo oluphezulu kunembhobho we-PE 80 enobukhulu obufanayo bodonga. Okwesibini, kwaye ngokuqhelekileyo, ungasebenzisa umbhobho we-PE 100 onodonga oluncinci ukuze ufumane umlinganiselo ofanayo woxinzelelo. Udonga oluncinci luthetha izinto ezincinci, okwenza umbhobho ube lula kwaye udla ngokuba neendleko eziphantsi. Ikwanika umbhobho ububanzi obukhulu bangaphakathi, nto leyo ephucula iimpawu zokuhamba kwamanzi.

Ithetha ukuthini i-PE 100 grade kumbhobho we-HDPE?

Ubona "i-PE 100 Grade" kwiphepha leenkcukacha. Kulula ukuyityeshela njengelinye igama lobuchwephesha, kodwa eli banga lichaphazela ngokuthe ngqo ukusebenza kombhobho kunye nokuthembeka kwexesha elide.

Umbhobho we-HDPE “we-PE 100 grade” uqinisekisiwe ukuba wenziwe nge-resin ye-PE 100 esebenza kakhulu. Oku kuqinisekisa amandla ayo aphezulu (10.0 MPa MRS), umlinganiselo ogqwesileyo woxinzelelo, kunye nokumelana okuphezulu ekukhuleni okucothayo kweentanda, okuqinisekisa ubomi benkonzo ende.

Xa ubona “Ibanga le-PE 100"," sisiqinisekiso somgangatho nokusebenza. Kuthetha ukuba umbhobho awenziwanga nje kuphela ngeplastiki eqhelekileyo; wenziwe nge-resin eyenzelwe ngokukodwa kwaye yavavanywa ukuze ihlangabezane nomgangatho ophezulu. Ngaphandle kwamandla aphezulu, olu didi lubonelela ngezinye izibonelelo ezibalulekileyo. Enye yezona zibalulekileyo kukuxhathisa kwayo okuphezulu kwiUkukhula Okucothayo Kokuqhekeka (i-SCG)Ngexesha lokufakelwa, imibhobho inokufumana imikrwelo emincinci okanye amaqhuqhuva. Kwizinto ezikumgangatho ophantsi, ezi ziphene zincinci zinokukhula kancinci zibe yimfanta enkulu kwiminyaka emininzi yokujikeleza koxinzelelo, ekugqibeleni zibangele ukuba umbhobho ungasebenzi. I-PE 100 yenzelwe ukumelana noku, iyenza ihlale ixesha elide kwaye ixolele iimeko zokufakelwa zehlabathi lokwenyani. Lukhetho olufanelekileyo lwemibhobho eza kugqunywa kwaye kufuneka ihlale amashumi eminyaka ngaphandle kweengxaki.

Kutheni i-modulus ye-elasticity ye-PE 100 ibalulekile?

Ufunda "imodulus of elasticity" kwiphepha ledatha aze amehlo akho akhanye. Eli gama lobuchwephesha libonakala lingabalulekanga, kodwa eneneni lichaza enye yezona nzuzo zibalulekileyo zezinto ezibonakalayo.

Imodulus yokuthamba ilinganisa ukuqina. I-PE 100 inemodulus ephantsi, nto leyo eyenza ukuba iguquguquke kakhulu. Oku kuvumela umbhobho ukuba ugobe ujikeleze imiqobo, unikezelwe ngeekhoyili ezinde, kwaye usetyenziswe kwiindlela zokufakela ezingenamngxuma, nto leyo enciphisa kakhulu iindleko zokufakela.

Kubalulekile ukungabhidanisi amandla nokuqina. Izinto ezifana neglasi ziqinile kakhulu, kodwa azinamandla xa zitshayiswa kuba zibuthathaka. I-PE 100 inamandla kakhulu kwaye iguquguquka kakhulu. Olu kuguquguquka luluncedo olukhulu ngexesha lokufakelwa. Kwiidayamitha ezincinci, singabonelela ngombhobho ngeekhoyili ezinde zeemitha ezili-100 nangaphezulu. Oku kuthetha ukuba kufuneka amalungu ambalwa, nto leyo egcina ixesha elininzi kwaye isuse iindawo ezibuthathaka. Kwiidayamitha ezinkulu, olu kuguquguquka luvumela umbhobho ukuba usetyenziswe kwiindlela zokufakela zanamhlanje ezifanaUkubhola Ngokuthe Tye (HDD)Oku kuvumela abafaki bepayipi ukuba batsale umbhobho ngaphantsi komhlaba ngaphandle kokumba umsele omde nophazamisayo. Oku kulungele ukuwela imilambo, iindlela, okanye iindawo ezinobuthathaka kokusingqongileyo. Kwilizwe elifana ne-Indonesia elinomhlaba owahlukeneyo, olu hlengahlengiso lunokonga imali eninzi kwiindleko zokufakela xa kuthelekiswa nemibhobho eqinileyo.

Ngaba i-PE 100 ingcono kune-PVC?

I-PVC yinto eqhelekileyo kakhulu kwipayipi, kwaye mhlawumbi uqhelene nayo. Idla ngokuba nexabiso eliphantsi lokuqala, ngoko kutheni ufanele utshintshele kwi-PE 100?

I-PE 100 ingcono kakhulu kwii-mains ezingcwatyiweyo. Iingenelo zayo eziphambili kune-PVC kukuguquguquka kwayo, ukumelana okuphezulu kwempembelelo, kunye namalungu adibeneyo angavuziyo. Amalungu e-PVC afakwe i-solvent-welded okanye ane-gasket adla ngokuba yeyona ndawo ibuthathaka kwinkqubo, ingxaki epheliswa ngokupheleleyo yi-fusion welding.

Nangona zombini ezi zinto zilungile, zenzelwe amandla ahlukeneyo. Eyona nzuzo inkulu ye-PE 100 yindlela yokudibanisa.

Izihlanganisi zezona zibalulekileyo. Xa ufudumeza i-fuse yombhobho we-PE 100, isihlanganisi siba yiplastiki enye, eqhubekayo. Ayinakuvuza. Nge-PVC, usebenzisa i-weld yesinyibilikisi sekhemikhali okanye i-gasket yerabha. Ezi zihlanganisi zihlala ziyindawo yokuqala apho ukuvuza kuya kwenzeka khona kwixesha elide. Kuyo nayiphi na imibhobho efihliweyo apho ukulungiswa kuya kuba kubi kakhulu kwaye kunzima, isihlanganisi esiqinisekisiweyo se-PE 100 esingenako ukuvuza senza kube lutyalo-mali oluphezulu lwexesha elide.

Isiphelo

I-PE 100 ingaphezulu nje kwenani. Amandla ayo agqwesileyo, ukuguquguquka, kunye namalungu adibeneyo angavuziyo kwenza ukuba ibe lukhetho lwanamhlanje noluthembekileyo kuyo nayiphi na iprojekthi ebalulekileyo yokuhambisa imibhobho yexesha elide.
