HDPE gasi pombi yakasimba uye yakachengeteka, inonyanya kushandiswa mumaguta maginjiniya.
Hupenyu hwakareba
Kushandiswa kwakachengeteka kweanopfuura makore makumi mashanu.
Lex Kuchinjika
Iyo PE mutopota ine elongation pakuzorora kweanopfuura 500%. Icho hachizoputika pasi peshanduko dzakasiyana dzesuburface senge kudzikira kwepasi nekudengenyeka kwenyika, uye ine chengetedzo yepamusoro. Vakafugama nharaunda (R≥15D), hapana chikonzero chegokora majoini, iri nyore pakuvaka.
◎ Cold kuramba
Iyo yakawiriranwa yekuwedzera coefficient ye PE pombi iri 1.5X10-4mm / mm ° C, uye kureba kwayo kunenge kusingakanganisike neshanduko tembiricha. Hapana shanduko yemuviri inoitika nyangwe -80 ° C. Inonyanya kukodzera kumatunhu anotonhora zvakanyanya.
Eld Weldability
Pe pombi inogona kushandiswa kumagetsi kusanganisa kana kupisa-kusungunuka kubatana. Kubatana kwaro kwakakwana, kwakasimba uye hakumbofi kwakadonha.
◎ ngura nemishonga
Kunyudza muhydrochloric acid pakushambidza kwemukati. Mune sulfuric acid (≤70%), nitric acid (≤25%), phosphoric acid, hydrofluoric acid, yakaoma acid (-10%) nemimwe mhinduro, mapaipi ePE haana kukanganiswa.
◎ Alkali uye zvisina kujairika munyu
Pe pombi inonyudzwa mune dzakasiyana lye, inorganic munyu uye mvura yegungwa pa60 ℃, PE pombi haigadzike.
◎ Zvinhu zvakasikwa
Pe pombi inogona kumira inogadziriswa solvents yakadai sehydrogen peroxide uye methyl peturu pane yakajairwa tembiricha, uye PE pombi haizokanganisa.
◎ Kushanda
Pe pombi yakareruka uremu (chete 1/7 yesimbi pombi) uye ine mukana wakanaka wekuchinja. De16-De75 pombi inogona kukuvadzwa kuitira nyore kutakura uye kuvaka.
