Amapayipi Epulasitiki Aqinisiwe E-Fiberglass: Ipayipi Elisha Elihlanganisiwe Elinokusebenza Okuphezulu kanye Nezicelo Ezibanzi
Amapayipi epulasitiki aqiniswe nge-fiberglass(amapayipi e-FRP) angamapayipi ahlanganisiwe enziwe ngokuqinisa i-fiber yengilazi kanye ne-resin njenge-matrix, anikeza kokubili izakhiwo ezilula neziqinile. Amelana nokugqwala futhi kulula ukuwafaka, abe yindlela engcono kakhulu yamapayipi ensimbi endabuko kumaphrojekthi okwakha kanye nezinhlelo zokudlulisa amandla. Ngezansi umbono ohlanganisa izici zezinto zokwakha, amazinga okukhiqiza, kanye nedatha yemakethe.
Incazelo kanye nokwakheka kwezinto
Uhlelo oluyinhloko lwezinto zamapayipi e-FRP lunamathela ezindinganisweni eziqinile zikazwelonke:
Isendlalelo sokuqinisa sisebenzisa i-fiber yengilazi engena-alkali noma ephakathi nendawo engasontekile (GB/T 18369-2008), lapho inani le-fiber lithinta ngqo ukuqina kwendandatho;
I-matrix ye-resin iqukethe i-resin ye-polyester engagcwalisiwe (GB/T 8237) noma i-epoxy resin (GB/T 13657). I-resin yezinga lokudla (GB 13115) iyimpoqo kumapayipi amanzi aphuzwayo;
Ingqimba egcwele isihlabathi iqukethe isihlabathi se-quartz (ubumsulwa be-SiO₂ >95%) noma i-calcium carbonate (ubumsulwa be-CaCO₃ >98%), kanye nokuqukethwe komswakama okulawulwa ngokuqinile ngaphansi kuka-0.2% ukuqinisekisa ukunamathela okuqinile phakathi kwezingqimba.
Ubuchwepheshe Bokwakha
Izinqubo ezijwayelekile zifaka phakathi ukugoqa okuqondile, ukuphonswa kwe-centrifugal, kanye nokugoqa okuqhubekayo. Inqubo yokugoqa ivumela ukulungisa isilinganiso samandla phakathi kweziqondiso ze-axial kanye neziyindilinga ngokuklama ama-engeli e-fiber. Ubukhulu besendlalelo esigcwele isihlabathi buthinta ngqo isilinganiso sokuqina kwepayipi.
Izixazululo Zokuxhumana
Beka phambili izivalo ze-O-ring zohlobo lwesokhethi (ezikwazi ukwamukela ukuguqulwa kokushisa okungu-±10mm). Ngezicelo zamakhemikhali, kunconywa ukuxhumeka kwe-flange (izilinganiso zokucindezela kwe-PN10/PN16). Ukufakwa kumele kuhambisane ngokuqinile nemininingwane yokusebenza kwephuzu eliphindwe kabili.
Izimo Ezijwayelekile Zokusebenza
Amanzi Okudonsa Izakhi: Amapayipi amakhulu (DN800+) angathatha indawo yamapayipi ekhonkrithi. Njengoba i-coefficient yangaphakathi yokuqina ingu-0.0084 kuphela, amandla okugeleza adlula amapayipi e-HDPE ngo-30%.
Amapayipi Kagesi: Ukufakwa kokungcwaba okuqondile okunokuqina kwendandatho okungu-≥8 kN/m² kuqeda isidingo sokufakwa kwekhonkrithi.
Ukuhanjiswa Kwamakhemikhali: Ukumelana ne-asidi ne-alkali kuhlangabezana nezindinganiso ze-ASTM D543, kanye nokuphila komklamo okungaphezu kweminyaka engama-50.
Ukunisela Kwezolimo: Isisindo sengxenye eyodwa kwezine kuphela yamapayipi ensimbi, izindleko zokuhamba kanye nokufakwa kwawo singancishiswa ngaphezu kuka-40%.
Isimo Semboni Nokuhlaziywa Kwethrendi
Usayizi Wemakethe
Umhlaba wonkeIpayipi le-FRPImakethe kulindeleke ukuthi ifinyelele ku-RMB 38.7 billion (cishe ama-USD 5 billion) ngo-2025, ikhule ibe yi-RMB 58 billion ngo-2032 (CAGR: 5.97%). Ngaphakathi kwezingxenye, amapayipi e-epoxy resin ezisetshenziswayo zobunjiniyela basolwandle abonisa izinga lokukhula elingu-7.2%.
