PE Cov Yeeb Nkab Dej
Kev faib tawm ntawm PE Cov Yeeb Nkab Dej
Muaj tag nrho 98 yam khoom ntawm PE100 qib kav dej rau kev muab dej, uas muab faib ua 5 qib raws li qhov siab: PN0.6MPa, PN0.8MPa, PN1.0MPa, PN1.25Mpa, thiab PN1.6Mpa, tag nrho ntawm 22 qhov kev qhia tshwj xeeb. Nws yog siv rau kev muab dej hauv nroog thiab cov chaw nyob hauv tsev, ntawm cov qib siab uas xav tau los ntawm kev muab dej hauv nroog yog qhov siab heev, thiab qib siab ntawm
cov network hauv tsev neeg tsawg heev;
Cov yam ntxwv ntawm PE Cov Yeeb Nkab Dej
1. Lub neej ua haujlwm ntev: cov khoom muaj 2-2.5% ntawm cov pa roj carbon dub sib npaug, uas tuaj yeem khaws cia lossis siv sab nraum zoov hauv huab cua qhib rau 50 xyoo; Cov khoom siv inert, tiv taus tshuaj lom neeg zoo, cov tshuaj lom neeg hauv av yuav tsis ua rau muaj kev puas tsuaj rau cov yeeb nkab.
2. Kev tiv thaiv zoo ntawm qhov kub qis: qhov kub qis heev, thiab nws tuaj yeem siv tau zoo ntawm -60 ° C. Vim yog qhov tiv thaiv zoo ntawm cov khoom siv, cov yeeb nkab yuav tsis tawg thiab tawg thaum lub caij ntuj no.
3. Kev tiv thaiv kev ntxhov siab thiab kev hnav tsis zoo: Nws muaj lub zog shear siab, tiv thaiv khawb zoo heev thiab tiv thaiv kev hnav tsis zoo, uas tuaj yeem zam kev puas tsuaj rau lub raj xa dej thaum lub sijhawm tsim kho.
4. Kev ywj pheej zoo heev, txo cov nqi teeb tsa: Kev ywj pheej zoo ua rau cov khoom yooj yim khoov. Hauv kev tsim kho vaj tse, cov teeb meem tuaj yeem hla dhau los ntawm kev hloov pauv ntawm cov kav dej, txo cov khoom siv yeeb nkab thiab cov nqi teeb tsa.
5. Muaj zog tiv taus kev sib tsoo ntawm lub hauv paus: Qhov ntev ntawm HDPE cov yeeb nkab dej tawg ntau tshaj 500%, thiab nws muaj kev hloov pauv zoo rau kev sib tsoo tsis sib xws ntawm lub hauv paus thiab kev ua tau zoo tiv thaiv av qeeg.
6. Kev sib txuas ruaj khov, tsis muaj qhov xau: Cov kav dej txuas nrog hluav taws xob thiab kub yaj, lub zog siab thiab lub zog tensile ntawm qhov sib koom ua ke siab dua lub zog ntawm lub cev yeeb nkab.
7. Cov txheej txheem tsim kho uas hloov tau yooj yim: Ntxiv rau cov txheej txheem tsim kho kev khawb av ib txwm muaj, ntau yam thev naus laus zis tshiab uas tsis muaj qhov av kuj tseem siv tau rau kev tsim kho, xws li kev rub cov yeeb nkab, kev khawb qhov chaw, cov yeeb nkab hauv qab, cov yeeb nkab tawg, thiab lwm yam.
Vim Li Cas Thiaj Xaiv GKM PE Cov Yeeb Nkab Dej
Cov yeeb nkab PE uas peb lub tuam txhab tsim tawm yog ua los ntawm PE100 uas xa tawm los ntawm Borealis thiab Korea Petrochemical, thiab extruded los ntawm lub tshuab extruder uas xa tawm los ntawm lub teb chaws Yelemees Battenfeld. Nws yog tib lub chaw tsim khoom hauv Northwest Tuam Tshoj uas tuaj yeem tsim cov yeeb nkab PE loj dn630mm; Cov khoom muaj kev ywj pheej zoo, tiv taus corrosion, lub teeb yuag thiab tiv taus kev cuam tshuam zoo heev, thiab lwm yam., Kev sib txuas yeeb nkab siv lub qhov (socket) kub yaj, lub pob kub yaj thiab kev sib txuas electrofusion, thiab lwm yam, kom cov yeeb nkab, cov khoom sib xyaw ua ke ua ib qho. Lub kaw lus muaj kev nyab xeeb thiab txhim khu kev qha, nrog tus nqi tsim kho qis. Cov lus qhia, qhov loj me thiab kev ua tau zoo ntawm cov yeeb nkab PE ua raws li cov kev cai ntawm GB/T13663-2000 tus qauv. Kev ua haujlwm huv si ua raws li GB/T17219 tus qauv thiab cov cai ntsuas kev nyab xeeb ntawm Ministry of Health, thiab tau tsim kho sai hauv kev siv engineering.
