High density Polyethylene Pipe Giredhi
HDPE pombi giredhi ine yakafara kana bimodal kugovera kwema molecular huremu.Iyo ine yakasimba creep resistance uye yakanaka chiyero chekuomarara uye kuoma.Inogara yakasimba uye ine sag yakaderera kana ichigadziriswa.Mapombi anogadzirwa uchishandisa iyi resin ane simba rakanaka, kusimba uye kupikisa kuramba uye yakanakisa pfuma yeSCG neRCP..
Iyo resin inofanira kuchengetwa munzvimbo yakaoma, yakaoma uye kure nemoto uye zuva rakananga.Hazvifanirwe kuunganidzwa pamhepo.Panguva yekufambisa, zvinhu zvacho hazvifanirwe kuvhenekerwa nezuva rakasimba kana kunaya uye hazvifanirwe kutakurwa pamwe chete nejecha, ivhu, zvimedu zvesimbi, marasha kana girazi.Kufambisa pamwe chete nezvinhu zvine chepfu, zvinopisa uye zvinopisa zvinorambidzwa zvachose.
Application
HDPE pombi giredhi inogona kushandiswa mukugadzirwa kwepombi dzekumanikidza, senge pombi dzemvura dzakamanikidzwa, mapaipi egasi emafuta uye mamwe mapaipi emaindasitiri.Inogona zvakare kushandiswa kugadzira mapaipi asina-kudzvanywa akadai semapaipi ane madziro ane mbiri, madziro anomonereka pombi, silicon-core pombi, pombi dzekudiridza dzekurima uye mapombi ealuminium emusanganiswa.Pamusoro pezvo, kuburikidza nereactive extrusion (silane cross-linking), inogona kushandiswa kugadzira crosslinked polyethylene pombi (PEX) yekupa mvura inotonhora uye inopisa.
