PE pombi (HDPE pombi) inogadzirwa nepolyethylene seyakanyanya mbishi zvinhu, ichiwedzera antioxidants, kabhoni dema uye mavara emhando.Iyo inoratidzirwa nekushomeka kwakadzika, yakakwira chaiyo simba, yakanaka yakadzika tembiricha kuramba uye kuoma, uye tembiricha yekushongedza inogona kusvika -80 ° C.
PE pombi plastiki inogona kugadziriswa uye kuumbwa nenzira dzakasiyana-siyana kugadzira zvigadzirwa zvakasiyana semafirimu, mashiti, mapaipi, profiles, nezvimwe;uye yakanakira kucheka, kubatanidza uye "welding" kugadzirisa.Purasitiki iri nyore kuisa ruvara uye inogona kugadzirwa kuva mavara akajeka;inogonawo kugadziriswa nekudhinda, electroplating, kudhinda uye embossing, ichiita mapurasitiki akapfuma mumigumisiro yekushongedza.
Mapurasitiki akawanda ane simba risingaperi rinopesana neasidhi, alkali, munyu, etc. pane simbi zvinhu uye zvimwe inorganic zvinhu, uye anonyatsokodzera magonhi nemahwindo, uriri, madziro, etc. mumakemikari zvinomera;thermoplastics inogona kunyungudutswa nemamwe organic solvents, nepo thermosetting mapurasitiki ari Iyo haigone kunyungudika, kumwe kuzvimba chete kunogona kuitika.Plastics zvakare ine yakanaka corrosion kuramba kumvura yezvakatipoteredza, kunyura kwemvura yakaderera, uye inogona kushandiswa zvakanyanya mumapurojekiti asina mvura uye hunyoro.
Iko kupisa kwekupisa kwePE pombi mapurasitiki kazhinji haina kukwirira.Kana yaiswa pasi pemitoro pakupisa kwepamusoro, inoita kupfava nekuremara, kana kutoora nekuora.Tembiricha yekupisa yekupisa yeyakajairwa thermoplastics i60-120 ° C, uye mhando shoma chete dzinogona kushandiswa kwenguva yakareba pakutenderera 200 ° C..Mamwe mapurasitiki ari nyore kubata moto kana kupisa zvishoma nezvishoma, uye huwandu hukuru hwehutsi hunokatyamadza huchagadzirwa pakutsva, zvichikonzera vanhu vanokuvara kana zvivakwa zvabatira moto.Iyo coefficient yemutsara wekuwedzera kwepurasitiki yakakura, iyo yakakura 3-10 nguva yakakura kupfuura iyo yesimbi.Nokudaro, deformation yekushisa yakakura, uye zvinhu zvinokuvadzwa nyore nyore nekuda kwekuunganidza kwekupisa kwekushisa.
Nekuda kwekuita kwayo kwakadzikama tembiricha uye kuoma, inogona kuramba kukuvara kwemotokari uye mechaniki vibration, chando-thaw chiito uye kamwe kamwe shanduko mukumanikidza kushanda.Nokudaro, mapaipi akavharidzirwa anogona kushandiswa kuisa kana kurima kuvaka, iyo yakanakira kuvaka uye yakaderera mumutengo weinjiniya;Rusvingo rwepombi rwakatsvedzerera, kuyerera kwepakati nepakati kudiki, kushandiswa kwesimba kwepakati pekufambisa kwakadzikira, uye haina kusvibiswa nekemikari nemahydrocarboni emvura mukati mekufambisa.Mapaipi epakati uye akakwira density PE akakodzera gasi remumaguta nemapaipi egasi chaiwo.Low-density PE mapaipi anokodzera pombi dzemvura yekunwa, tambo conduits, pombi dzekupfapfaidza dzekurima, pombi dzechiteshi chepombi, nezvimwewo. Mapaipi ePE anogonawo kushandiswa mukugovera mvura, kudhiraivha uye madhiraini emhepo muindasitiri yemigodhi.
