Kuchinja-chinja
Iko kuchinjika kwepombi yepolyethylene inobvumira kuti ive yakakombama pamusoro, pasi, uye kutenderedza zvipingamupinyi pamwe nekuita kukwirira nekuchinja kwekwakananga.Mune zvimwe zviitiko, kuchinjika kwepombi kunogona kubvisa zvinoshamisa kushandiswa kwemafittings uye kuderedza zvakanyanya mari yekuisa.
CHUANGRONG PE pombi inogona kukotamiswa kusvika padiki diki pakati pe20 kusvika 40 nguva yedhayamita yepombi, izvo zvinonyanya kuenderana neSDR yeimwe pombi.

Kuwanda kwezvinhu zvePE ingori 1/7 chete yesimbi. Huremu hwepombi yePE ishoma pane hwekongiri yakakandwa simbi, kana pombi yesimbi. Iyo PE pombi system iri nyore kubata nekuisa, uye kuderedzwa kwesimba remurume uye midziyo zvinodiwa zvinogona kukonzera kuchengetwa kwekuchengetedza.
Iyo hydrostatic design hwaro hweCHUANGRONG pombi yakavakirwa payakakura hydrostatic yekuongorora data yakaongororwa neyakajairwa indasitiri nzira.Mafambiro enguva refu yekupikiswa kwemukati mukati kunopiwa neiyo hydrostatic simba curve inoenderana neEN ISO 15494 standard (ona chikamu X). Miganho yekushandiswa kwepombi uye mafittings, sezvakaratidzwa mudhiyagiramu-tembiricha, inogona kutorwa kubva kune aya macurve, anoratidza kuti pombi ine tarisiro yehupenyu ingangoita makore makumi mashanu kana ichitakura mvura pa20 ℃. Mamiriro emukati nekunze ezvakatipoteredza anogona kushandura hupenyu hunotarisirwa kana kushandura hwaro hwedhizaini yakakurudzirwa yechikumbiro chakapihwa.

Mamiriro ekunze emapurasitiki anoitika nekushatisa kwepasi, kana kuti oxidation, nekuda kwekubatanidzwa kwemwaranzi ye ultra violet, kuwedzera tembiricha, uye kunyorova kana pombi dzakachengetwa munzvimbo dzakashama. Black polyethlence pombi, ine 2 kusvika 2.5% yakakamurwa zvakakamurwa kabhoni nhema, inogona kuchengetwa kunze munzvimbo zhinji kwemakore akawanda pasina kukuvara kubva kune Ultra-violet exposure. Mamwe mavara akadai semachena, bhuruu, yero kana lilac haana kugadzikana kwakafanana neakasviba pigmented system uye nguva yekuratidzwa inofanirwa kugumira gore rimwe chete kuti zvichengetedzwe zvakanyanya. mwero unokurumidza kupfuura iwo mune kabhoni dema
yakagadzikana PE mapaipi.Mapaipi aya ane mavara haana kukurudzirwa kune pamusoro pevhu mafomu.
Polyethylene pombi inogona kushandiswa patembiricha kubva-50°C kusvika +60°C. Pakupisa kwepamusoro, kusimba kwesimba uye kuoma kwezvinhu zvinoderedzwa Naizvozvo, ndapota bvunza dhiyabhorosi-tembiricha dhayagiramu. Kune tembiricha dziri pasi peO°Cit inofanirwa kuve nechokwadi kuti yepakati haionde, kudzivirira kukuvadzwa kwepombi system.
Kufanana nese thermoplastics, PE inoratidza kuwedzera kwekushisa kwesimbi. Yedu PE ine coefficent yemutsara wekupisa kwekuwedzera kwe 0.15 kusvika 0.20mm/m K, iyo iri 1.5 nguva yakakura kupfuura iyo eg. PVC . Sezvo izvi zvichirangarirwa panguva yekuronga kwekuiswa hakufaniri kuva nezvinetso munyaya iyi.
The thermal conductivity is 0.38 W/m K.Nekuda kweiyo inokonzeresa insulation properties, PE piping system inonyanya hupfumi mukuenzanisa nehurongwa hwakagadzirwa nechinhu chakaita semhangura.

Polyethylene ndeyemapurasitiki anopisa.Okisijeni index inosvika 17%.(Zvinhu zvinopisa zvisingasviki 21% yeokisijeni mumhepo zvinoonekwa sezvinopisa).
PE inodonha uye coninues kupisa pasina soot mushure mekubvisa murazvo. Chaizvoizvo, zvinhu zvine chepfu zvinoburitswa nemaitiro ese ekupisa. Carbon monoxide ndiyo inonyanya kupisa chigadzirwa chine njodzi kuvanhu. Kana PE ichitsva, kunyanya kabhoni dhaibhorosi, kabhoni monoxide uye mvura inogadzirwa.
The self-ignition tembiricha i350 ℃ .
Zvinodzimisa moto zvinoshandiswa mvura, furo, carbon dioxide kana hupfu.
Biological Resistance
Mapombi ePE anogona kukuvara kubva kune zvipenyu zvakaita semajuru kana makonzo. Kuramba kurwiswa kunotarirwa nekuoma kwePE inoshandiswa, geometry yepe PE nzvimbo, uye mamiriro ekuiswa. Mumapaipi madiki dhayamita, zvikamu zvitete zvemadziro zvinogona kukuvadzwa nemajuru muzviitiko zvakanyanyisa. Nekudaro kukuvara kunowanzo kuverengerwa kurwiswa kwemujuru muPE kwakazoonekwa kuve nekuda kwezvimwe zvinokonzeresa kukuvara kwemuchina.
PE pombi masisitimu haawanzo kukanganiswa nezvisikwa zvipenyu muvhu, uye zvipenyu zvemugungwa, uye chimiro cheparafini chepombi yePE chinodzoreredza kuvakwa kwezvimedu zvemugungwa mubasa.
Electrical Properties
Nekuda kwekudzika kwemvura kunyura kwePE, maitiro ayo emagetsi haatombokanganiswa nekuenderera mberi kwemvura.Sezvo PE isiri-polar hydrocarbon polymer, inoshamisa insulator.Zvinhu izvi, zvisinei, zvinogona kuipisisa zvakanyanya nekuda kwekusvibiswa. , mhedzisiro yeoxidizing media kana mamiriro ekunze. Iyo chaiyo vhoriyamu kuramba ndeye> 1017 Ωcm; iyo dielectric simba i220 kV/mm.
Nekuda kwekugona kuvandudzwa kwekuchaja kwemagetsi, kungwarira kunokurudzirwa kana uchishandisa PE mumaapplication uko kune njodzi yemoto kana kuputika.
CHUANGRONGiindasitiri yekugovana uye yekutengesa yakabatanidzwa kambani, yakavambwa muna 2005 iyo yakatarisana nekugadzirwa kweHDPE Pipes, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, uye kutengeswa kwePlastiki Pipe Welding michina, Pipe Zvishandiso, Pipe.
