Mapulasitiki ambiri ali ndi mphamvu zowonongeka kwa asidi, alkali, mchere, etc. kuposa zipangizo zachitsulo ndi zinthu zina zakuthupi, ndipo ndizofunikira makamaka zitseko ndi mazenera, pansi, makoma, etc. mu zomera mankhwala; thermoplastics imatha kusungunuka ndi zosungunulira za organic, pomwe mapulasitiki a thermosetting ali Sizingasungunuke, kutupa kwina kokha kungachitike. Pulasitiki imakhalanso ndi kukana kwabwino kwa dzimbiri kumadzi achilengedwe, kuyamwa kwamadzi otsika, ndipo kumatha kugwiritsidwa ntchito kwambiri pamaprojekiti osalowa madzi ndi chinyezi.
PE payipi(HDPE pipe) imapangidwa ndi polyethylene monga zopangira zazikulu, kuwonjezera ma antioxidants, carbon black and coloring materials. Amadziwika ndi kachulukidwe otsika, mphamvu zenizeni zenizeni, kukana kutentha kochepa komanso kulimba, komanso kutentha kwa embrittlement kumatha kufika -80 ° C.
PE pulasitiki pulasitikiakhoza kukonzedwa ndi kupangidwa ndi njira zosiyanasiyana zopangira zinthu zosiyanasiyana monga mafilimu, mapepala, mapaipi, mbiri, etc.; ndipo ndi yabwino kudula, kugwirizana ndi "kuwotcherera" processing. Pulasitiki ndi yosavuta kukongoletsa ndipo imatha kupangidwa kukhala mitundu yowala; imathanso kukonzedwa ndi kusindikiza, electroplating, kusindikiza ndi embossing, kupanga mapulasitiki olemera muzokongoletsera.
Kukana kutentha kwaMapulasitiki a PEnthawi zambiri sipamwamba. Ikagwidwa ndi katundu pa kutentha kwakukulu, imakonda kufewetsa ndi kupunduka, kapena kuwola ndi kuwonongeka. Kutentha kwa kutentha kwa thermoplastics wamba ndi 60-120 ° C, ndipo mitundu yochepa yokha ingagwiritsidwe ntchito kwa nthawi yayitali pafupifupi 200 ° C. . Mapulasitiki ena ndi osavuta kugwira moto kapena kuwotcha pang'onopang'ono, ndipo utsi wambiri wapoizoni umapangidwa ukayaka, zomwe zimapangitsa kuvulala nyumba zikapsa. Coefficient of linear expansion of pulasitiki ndi yaikulu, yomwe ndi yokulirapo 3-10 kuposa yachitsulo. Choncho, kutentha kwa kutentha kumakhala kwakukulu, ndipo zinthuzo zimawonongeka mosavuta chifukwa cha kudzikundikira kwa kutentha kwa kutentha.
Chifukwa cha kutentha kwake kochepa kwambiri komanso kulimba kwake, imatha kukana kuwonongeka kwa galimoto ndi kugwedezeka kwa makina, kuchitapo kanthu kozizira komanso kusintha kwadzidzidzi kwa kuthamanga kwa ntchito. Choncho, mapaipi ophimbidwa angagwiritsidwe ntchito poyika kapena kulima zomangamanga, zomwe zimakhala zosavuta kumanga komanso zotsika mtengo waumisiri; Khoma la chitoliro ndi losalala, kukana kwapakati kwapakati kumakhala kochepa, kugwiritsa ntchito mphamvu kwa sing'anga yotumizira kumakhala kotsika, ndipo sikuwonongeka ndi ma hydrocarbons amadzimadzi mu sing'anga yotumizira. Kachulukidwe wapakatikati komanso wapamwambaPE mapaipindi oyenera gasi m'tauni ndi gasi mapaipi. Mapaipi otsika kwambiri a PE ndi oyenerera mapaipi amadzi akumwa, mipope ya chingwe, mapaipi opopera mbewu mankhwalawa, mapaipi opopera, ndi zina zambiri.
CHANGRONGndi kampani yophatikizira yogawana ndi malonda, yomwe idakhazikitsidwa mu 2005 yomwe imayang'ana kwambiri kupanga mapaipi a HDPE, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, ndi malonda a Pulasitiki Pipe Welding makina, Zida za Chitoliro, Pipe Repair Clamp ndi zina zotero.
