Ukuqonda iiPipe zeNsimbi ze-3PE: Isishwankathelo esipheleleyo

Kwizakhiwo zanamhlanje nakwiziseko zophuhliso, ukubaluleka kwezinto ezihlala ixesha elide nezithembekileyo kuyabonakala. Phakathi kwazo, iipayipi zentsimbi ze-3PE (ezaziwa ngokuba ziipayipi zentsimbi ze-polyethylene ezilwa nokugqwala ezineeleya ezintathu) zibalaseleyo ngokusebenza kwazo okuphezulu kunye nobomi benkonzo obude kakhulu. Ezi pipes, ezenziwe ziinkampani eziphambili kushishino ezifana neJindalai Steel Group, ziyilwe ngobuchule ukuze zimelane neemeko ezinzima zokusingqongileyo kwaye zinokumelana nokugqwala okugqwesileyo. Inkqubo yokuvelisa imibhobho yentsimbi ye-3PE ingqongqo kwaye icwangcisiwe, iqinisekisa ukuba imigangatho ephezulu yomgangatho iyafezekiswa. Okokuqala, imibhobho yentsimbi inyangwa ngaphezulu, kuquka ukucocwa nokususwa kwayo nayiphi na into engcolileyo enokuchaphazela ukuthembeka kwengubo. Emva koko kuza isakhiwo esichasene nokugqwala: umaleko wokuqala yi-epoxy powder (FBE): enobukhulu obungaphezulu kwe-100um, inokunamathela okuhle kakhulu kunye nokumelana nokugqwala, okuthintela ngempumelelo izinto zangaphandle ezifana nokufuma kunye neegesi ekuguguleni umphezulu wombhobho wentsimbi. Umaleko wesibini yi-adhesive (AD): i-adhesive ye-copolymer enamaqela asebenzayo anamasebe, phakathi kwe-170-250um ubukhulu, edibanisa umaleko we-epoxy powder kunye nomgangatho we-polyethylene, eqinisekisa ukubopha okuqinileyo phakathi kwezi zigaba zintathu. Umaleko wesithathu, i-polyethylene (PE), inobukhulu be-1.8-3.7 mm kwaye inokumelana nokugqwala okuhle kakhulu, ukumelana nokuphuma komphunga wamanzi, kunye neempawu zoomatshini, ikhusela umbhobho wentsimbi kwiimpembelelo zokusingqongileyo. Olu gquma lunezingqimba ezininzi aluphuculi kuphela ukuqina kombhobho kodwa lukwandisa kakhulu ubomi balo benkonzo. Iipayipi zentsimbi ze-3PE zisetyenziswa kakhulu kwaye zezona zikhethwayo kumashishini amaninzi. Ezi pipes zisetyenziswa kakhulu ekuthuthweni kweoyile negesi, kwiinkqubo zokubonelela ngamanzi, kunye nonyango lwamanzi amdaka. Ulwakhiwo lwazo oluqinileyo kunye nokumelana nokugqwala okugqwesileyo kuzenza zilungele ukufakwa phantsi komhlaba, apho iipayipi zentsimbi eziqhelekileyo zichaphazeleka kukugqwala ngokukhawuleza kwiindawo ezifumileyo nezomhlaba. Ngaphezu koko, iipayipi zentsimbi ezimelana nokugqwala ze-3PE zisetyenziswa kakhulu kwiiprojekthi zamandla avuselelekayo, ezifana nokuveliswa kwamandla obushushu kunye nomoya, apho ukuthembeka kunye nobomi benkonzo bubaluleke kakhulu. Unyango lomphezulu lubalulekile ekusebenzeni kwemibhobho yentsimbi ye-3PE. Unyango lomphezulu wokuqala linyathelo elibalulekileyo lokuqinisekisa ukunamathelana okusebenzayo phakathi kwe-epoxy primer kunye ne-substrate yentsimbi. Oku kulandelwa kukusetyenziswa kwengubo ye-polyethylene enamaleko amathathu, inkqubo yokufaka ilawulwa ngokungqongqo ukuqinisekisa ubukhulu kunye nokugquma okufanayo. Unyango lokugqibela lomphezulu luquka ukucocwa kwengubo ukuze kufezekiswe ubulukhuni kunye nokuxhathisa izinto ezingqongileyo. Le nkqubo ibanzi yonyango lomphezulu ayigcini nje ngokuphucula ubuhle bemibhobho kodwa ikwaqinisa ukumelana kwayo nokugqwala kunye nokuxhathisa ukurhawuzelelwa koomatshini. Iipayipi zentsimbi ze-3PE ziyilwe kucingwa ngamandla aphezulu kunye nokuqina. Umaleko wentsimbi yangaphakathi ubonelela ngokuqina kwesakhiwo okufunekayo, ngelixa uqweqwe lwe-polyethylene olunezintlu ezintathu lumelana ngempumelelo nezinto ezirhabaxa. Olu dibaniselwano lwenza iipayipi zingabi zomelele kuphela kodwa zibe lula, nto leyo eyenza kube lula ukuphathwa kunye nokufakwa kwazo. Ngaphezu koko, ukuguquguquka kwee-polyethylene layers kuvumela inqanaba lokuguquguquka, kunciphisa umngcipheko wokuqhekeka okanye ukuqhekeka phantsi koxinzelelo. Ukuqukumbela, iipayipi zentsimbi ze-3PE, ingakumbi iipayipi zentsimbi ezilwa nokugqwala ze-TPEP, zimele inkqubela phambili ebalulekileyo kubuchwepheshe bokufaka iipayipi. Ngeenkqubo zazo zokuvelisa eziqinileyo, uluhlu olubanzi lwezicelo, kunye nobuchwepheshe bonyango oluphezulu lomphezulu, zilungele amashishini afuna izisombululo ezithembekileyo nezihlala ixesha elide. I-Jindalai Steel Group iyaqhubeka nokukhokela ukuveliswa kwezi payipi zentsimbi ezintsha, iqinisekisa ukuba ziyahlangabezana nemigangatho ephezulu kunye nokusebenza. Njengoko iimfuno zeziseko zophuhliso zikhula, ukubaluleka kwezi zinto ziphambili kuya kwanda kuphela, okuqinisa indawo ephambili yeepayipi zentsimbi ze-3PE kubunjineli banamhlanje nolwakhiwo.
