Kurongwa kwePE mapaipi kubva kune vatengesi
Pakati pemapurasitiki einjiniya ese, HDPE inomira pekutanga pakati pemapurasitiki maererano nekupfeka kuramba uye inobata maziso. Kukwirisa huremu hwemamorekuru, ndiko kunowedzera kusapfeka zvinhu, kutopfuura zvinhu zvakawanda zvesimbi (senge kabhoni simbi, simbi isina tsvina, bhuronzi, nezvimwewo). Hupenyu hwesevhisi pasi pekuora kwakasimba uye mamiriro ekupfeka zvakanyanya ndeye 4-6 nguva yepombi dzesimbi uye 9 nguva yeyakajairika polyethylene; Uye kuvandudza kugona kwekufambisa ne20%. Iyo inodzoreredza murazvo uye anti-static zvivakwa zvakanaka uye zvinosangana nezvinodiwa zvakajairwa. Hupenyu hwesevhisi hwepasi pevhu hunodarika makore makumi maviri, nehupfumi hwakakosha, kuramba kwemhedzisiro, kuramba kupfeka, uye akakosha maviri ekupikisa mhedzisiro.
PE mapaipi ekuyerera kwetsvina, inozivikanwawo seyepamusoro-density polyethylene pombi, inozivikanwawo seHDPE. Iri rudzi rwepombi rinowanzo shandiswa semanisipala engineering pombi, kunyanya muindasitiri yekuchenesa tsvina. Nekuda kwehunhu hwayo hwekuramba kupfeka, acid resistance, corrosion resistance, high tembiricha kuramba, uye high pressure resistance, zvishoma nezvishoma yakatsiva mapaipi echinyakare semapombi esimbi nemapombi esimende pamusika. Kunyanya nekuti iyi pombi haina uremu uye iri nyore kuisa nekufambisa, ndiyo sarudzo yezvinhu zvitsva. Apo vashandisi vanosarudza mapaipi akagadzirwa nechinhu ichi, ivo vanofanirawo kubhadhara zvakanyanya kune zvinotevera pfungwa: 1. Kusarudzwa kwepurasitiki pombi zvinhu kunofanira kunyanya kuchenjerera. Kune zviuru zvemagiredhi e polyethylene raw materials, uye kune mbishi zvinhu zvakaderera sezviuru zvishoma zveyuan patani pamusika. Zvigadzirwa zvinogadzirwa kubva kune izvi zvigadzirwa hazvigone kuvakwa, zvikasadaro zvinokonzeresa kurasikirwa kukuru kwekugadzirisa. 2. Kusarudzwa kwevagadziri vemapaipi kunofanirwa kuve kwakavakirwa kune vanogadzira zviri pamutemo uye nyanzvi. 3. Paunosarudza kutenga PE mapaipi, zvinodikanwa kuita pa-site kuongororwa kwemugadziri kuti uone kana vane simba rekugadzira.
Mapombi ePE ekupa mvura chinhu chinotsiviwa chepombi dzesimbi dzechinyakare uye pombi dzemvura yekunwa dzepolyvinyl chloride. Iyo pombi yekupa mvura inofanirwa kumira nehumwe huwandu hwekudzvanywa, kazhinji ichishandisa PE resin ine huremu hwemamorekuru uye yakanaka michina zvinhu, senge HDPE resin. LDPE resin ine yakaderera kusimba simba, kushomeka kudzvinyirira kuramba, kusimba kusimba, kushomeka kwechimiro chekugadzikana panguva yekuumbwa uye kugadzirisa, uye inonetsa kubatanidza, ichiita kuti isakodzere sechinhu chemvura yekumanikidza pombi. Asi nekuda kwehutsanana hwepamusoro zviratidzo, PE, kunyanya HDPE resin, yave chinhu chinowanzoshandiswa kugadzira pombi dzemvura yekunwa. HDPE resin ine yakaderera melt viscosity, yakanaka kuyerera, uye iri nyore kugadzirisa, saka sarudzo yemhando yekunyunguduka kwayo inewo yakakura, kazhinji ine MI pakati pe0.3-3g/10min.
Shandong Kungang Metal Technology Co., Ltd. inopa PE pombi gore rose, uye inogona kuchengetedza zvakasiyana-siyana uye mhando mudura. Kwemakore, kambani yedu yakanamatira kumusimboti we "mukurumbira, sevhisi, uye mhando hupenyu" mukuita kwekukurumidza kusimudzira nehunhu hwechokwadi. Takaunganidza simba rakasimba, takaisa hwaro hwakanaka hwemusika, uye takaita vadyidzani vazhinji kumba nekune dzimwe nyika. Kutarisira kubatana kwedu!
