Endaweni yokuvikelwa kokugqwala kwamapayipi ensimbi kanye nokufakwa kwama-polyethylene (3Lpe) e-polyethylene (3LPE) izimbobo ziye zaba umkhuba ojwayelekile. Lezi zimbozo zenzelwe ukuhlinzeka ngokuvikelwa okuqinile ezimweni zezemvelo ezingadala ukugqwala, ukuqinisekisa ukuthi isikhathi eside kanye nokwethenjwa kwengqalasizinda yensimbi. Kodwa-ke, ukufezekisa ukusebenza okuhle, kubalulekile ukuqonda ubukhulu balezi zimbozo. Kule bhulogi, sizohlola izinto ezibalulekile ezithonya ubukhulu be-3lpe coating kanye namasu wokulinganisa asetshenziselwa ukuqinisekisa ukuhambisana namazinga ezimboni.
Ukubaluleka kokuqina kwe-LPE coating
Izinhlelo ze-3Lpe zokuhlanganisa ezihlanganisiwe zihlanganisa i-epoxy primer, ukunamathela kwe-copolymer, kanye ne-polyethylene ungqimba lwangaphandle. Ungqimba ngalunye lubamba iqhaza elibalulekile ekuvikeleni i-wensimbi substrate kusuka ekugcekeni. Ubukhulu balezi zingqimba buthinta ngokuqondile ukusebenza kwe-coating. I-coating emncane kakhulu kungenzeka inganikeze isivikelo esanele, ngenkathi ukuhlanganiswa okunamandla kakhulu kungadala izinkinga ezinjengokuqhekeka noma ukunxenxa.
Izici ezibalulekile ezithinta ubukhulu be-coation
1. Indlela yesicelo: indlela yokusebenzisaI-3Lpe coatingkuzothinta kakhulu ubukhulu bawo. Izigqoko ezisetshenziswayo zefekthri, ezinjengalezo ezikhiqizwa esikhungweni sethu se-cangzhou, zivame ukufana kakhulu futhi zilawulwa kunezicelo zensimu. Lokhu kungaguquguquki kubalulekile ukuqinisekisa ukuthi ukuhlanganiswa kuhlangabezana nezidingo ezicacisiwe.
2. Izakhiwo ezibonakalayo: Izakhiwo zezinto zokwakha ezisetshenziswa kwinqubo yokuhlanganisa, kufaka phakathi ukubonana kwe-epoxy kanye nohlobo lwe-polyethylene, kuzothinta ubukhulu bokugcina. Ukuqonda lezi zici kusiza ukulungisa inqubo yokufaka ukufezekisa ubukhulu obufunayo.
3. Izimo zezemvelo: Izici ezifana nezinga lokushisa kanye nomswakama ngesikhathi sesicelo zingathinta ikhambi nokunamathelisa kwe-coating. Lezi zimo kumele zibhekwe ukuze kuqinisekiswe ukuthi ama-coating anamathela kahle futhi afinyelele ubukhulu obufunayo.
4. Ukulawulwa kwekhwalithi: Kubalulekile ukusebenzisa izindlela eziqinile zokulawula ikhwalithi ngesikhathi senqubo yokukhiqiza. Ukuhlolwa okujwayelekile nokuhlolwa okujwayelekile kungasiza ekuboneni noma yikuphi ukuphambuka kubukhulu bokuhlanganisa ukuze kulungiswe ukulungiswa kuqhubeke nokulandela ukulandelwa kwezindinganiso zezimboni.
Ukulinganisa ubuchwepheshe bokulinganisa ubuchwepheshe
Ukuqinisekisa lokhoI-3Lpe coating ubukhuluHlangana nezidingo ezicacisiwe, ukukalwa okunembile kokuqina kwe-coation kubalulekile. Izindlela eziningana zingasetshenziswa:
1. Ukungeniswa kwama-magnetic: Le ndlela yokuhlola ebhubhisayo ivame ukusetshenziselwa ukukala ubukhulu bezimbozo ezingezona ezibuluzini kuma-magretic substrates. Inikeza ukufundwa okusheshayo nokunembile, okwenza kube ukukhetha okuthandwayo embonini.
2. Ukuhlolwa kwe-Ultrasonic: lobu buchwepheshe busebenzisa amagagasi omsindo wemvamisa ephezulu ukukala ubukhulu be-coating. Iwusizo ikakhulukazi emboni elibanzi futhi ingafakwa ezingxenyeni ezahlukahlukene zezati.
I-3. Ukuhlolwa okubhubhisayo: Kwezinye izimo, isampula elincane lezinto ezihlanganayo linganqunywa futhi lilinganiswe ukuthola ubukhulu bokuhlanganisa. Ngenkathi le ndlela ihlinzeka ngezilinganiso ezinembile, ayilungele zonke izinhlelo zokusebenza ngenxa yamandla womonakalo kumkhiqizo ohlanganisiwe.
Ekuphetheni
Ukuqonda izinto ezibalulekile ezithinta ubukhulu be-3lpe coation kanye nokusebenzisa amasu wokulinganisa aphumelelayo kubalulekile ukuze kuqinisekiswe ukuvikelwa kokugqwala kwamapayipi ensimbi nokufakwa. Ifektri yethu yaseCangegzhou yasungulwa ngonyaka we-1993 futhi ihlanganisa indawo engamamitha-skwele angama-350,000. Sizibophezele ekukhiqizeni izigqoko ezisezingeni eliphakeme zefektri ezihlangabezana namazinga emboni aqinile. Ngokusebenza kwabasebenzi abazinikele kwe-680 kanye nempahla ephelele ye-RMB 680 million, sizibophezele ekuhlinzekeni izixazululo ezithembekile zokulwa nokuwohloka ukuze kuqinisekiswe ukuqina nokusebenza kwengqalasizinda yensimbi iminyaka ezayo.
