Kuchinjika
Kuchinjika kwepombi yepolyethylene kunoita kuti ikomberedzwe pamusoro, pasi, uye pakapoteredza zvipingamupinyi pamwe nekuchinja kukwirira uye divi.Mune zvimwe zviitiko, kuchinjika kwepombi kunogona kuderedza kushandiswa kwezvibatiso uye kuderedza zvakanyanya mari yekuisa.
Pombi yeCHUANGRONG PE inogona kukotama kusvika padanho riri pakati pe20 kusvika 40 dhayamita yepombi, izvo zvinonyanya kutsamira paSDR yepombi iyoyo.

Huremu hwakareruka
Tarisiro yeHupenyu
Kuwanda kwezvinhu zvePE kunongova 1/7 chete yesimbi. Huremu hwemapaipi ePE hushoma pane hwesimbi yakakandwa yekongiri, kana mapaipi esimbi. Sisitimu yemapaipi ePE iri nyore kubata nekuisa, uye kushomeka kwesimba revashandi nemidziyo zvinogona kukonzera kuchengetedza mari pakuiswa.
Hwaro hwekugadzira pombi yeCHUANGRONG hydrostatic hwakavakirwa padata rakakura rekuyedza hydrostatic rakaongororwa nenzira dzakajairwa dzeindasitiri. Maitiro enguva refu ekudzivirira kumanikidzwa kwemukati anopiwa ne hydrostatic strength curve zvichibva pa EN ISO 15494 standard (ona chikamu X). Miganhu yekushandisa pombi nezvigadziko, sezvakaratidzwa mu pressure-temperature diagram, inogona kuwanikwa kubva kuma curves aya, ayo anoratidza kuti pombi ine hupenyu hwemakore angangoita makumi mashanu pakutakura mvura pa20℃. Mamiriro ekunze emukati nekunze anogona kuchinja hupenyu hunotarisirwa kana kushandura hwaro hwekugadzira hunokurudzirwa hwekushandisa kwakapihwa.
Kuramba Kwemamiriro Ekunze
Zvivakwa zvekupisa
Kuchinja kwepurasitiki kunoitika nekuda kwekuora kwepasi, kana kuti oxidation, nekuda kwemhedzisiro yakabatana yemwaranzi ye ultra violet, kuwedzera tembiricha, uye hunyoro kana mapaipi akachengetwa munzvimbo dzakafumurwa. Pombi nhema ye polyethlence, ine 2 kusvika 2.5% kabhoni dema yakakamurwa zvakanaka, inogona kuchengetwa zvakachengeteka kunze munzvimbo zhinji dzemamiriro ekunze kwemakore mazhinji pasina kukuvara kubva pakusvibiswa ne ultra-violet. Kabhoni dema ndiyo imwe yekuwedzera inoshanda zvakanyanya yekuvandudza hunhu hwemamiriro ekunze epurasitiki. Mamwe mavara akadai sechena, bhuruu, yero kana lilac haana kugadzikana kwakafanana nemasikiriti matema ane pigment uye nguva yekusvibiswa inofanira kuganhurirwa kune gore rimwe chete kuti zvinhu zvirambe zvakanaka. Nemasisitimu aya emavara, zvikamu zvekunze zve oxidation zvinokura nekukurumidza kupfuura zviri mu carbon black.
mapaipi ePE akasimba. Mapaipi aya ane mavara haakurudzirwi kushandiswa pamusoro pevhu.
Mapaipi epolyethylene anogona kushandiswa patembiricha iri pakati pe-50°C kusvika +60°C. Patembiricha yakakwira, simba rekudhonza uye kuomarara kwechinhu chacho zvinodzikira. Saka, ndapota tarisa dhayagiramu yekupisa nekumanikidzwa. Kana tembiricha dziri pasi peO°C, Cit inofanira kuve nechokwadi chekuti medium haiome, kudzivirira kukuvara kwesystem yemapaipi.
Kufanana nethermoplastics dzese, PE inoratidza kuwedzera kwekupisa kwakanyanya kupfuura simbi. PE yedu ine coefficient yekuwedzera kwekupisa kwemutsara we0.15 kusvika 0.20mm/m K, iyo yakakura ka1.5 kupfuura semuenzaniso .PVC . Sezvo izvi zvichifungwa panguva yekuronga kuiswa, hapafanirwe kuve nematambudziko panyaya iyi.
Kufambiswa kwemhepo mukupisa kwemhepo i0.38 W/m K. Nekuda kwehunhu hwekudzivirira hunobva mukupisa, sisitimu yePE piping inonyanya kudhura kana tichienzanisa nesystem yakagadzirwa nezvinhu zvakaita semhangura.
Maitiro eKupisa
![V17B]@7XQ[IYGS3]U8SM$$R](http://cdn.globalso.com/cdchuangrong/V17B@7XQIYGS3U8SMR.jpg)
Polyethylene ndeyemapurasitiki anobvira moto. Okisijeni inokwana 17%. (Zvinhu zvinopisa zvine okisijeni iri pasi pe21% mumhepo zvinoonekwa sezvinogona kupiswa).
PE inodonhedza mvura yoramba ichitsva pasina tsvina mushure mekubvisa murazvo. Chaizvoizvo, zvinhu zvine chepfu zvinoburitswa nemaitiro ese ekupisa. Carbon monoxide inowanzova chinhu chine njodzi zvikuru kuvanhu. Kana PE yatsva, carbon dioxide, carbon monoxide nemvura zvinoumbwa.
Tembiricha yekuzvibatidza ndeye 350℃.
Zvinhu zvakakodzera pakudzimisa moto imvura, furo, kabhoni dhayokisaidhi kana upfu.
Kuramba Kwezvinhu Zvipenyu
Mapaipi ePE anogona kukuvadzwa nezvinhu zvipenyu zvakaita semasvosve kana makonzo. Kusakwanisa kurwisa kunoenderana nekuoma kwePE inoshandiswa, chimiro chenzvimbo dzePE, uye mamiriro ekuisa. Mumapaipi madiki ane dhayamita, zvikamu zvemadziro matete zvinogona kukuvadzwa nemajuru muzviitiko zvakanyanya. Zvisinei, kukuvara kunowanzo kukonzerwa nekurwiswa kwemajuru muPE kwakawanikwa kuti kunokonzerwa nezvimwe zvinhu zvinokonzera kukuvara kwemuchina.
Masisitimu emapaipi ePE haawanzo kanganiswa nezvisikwa zvipenyu zviri munyika uye mugungwa, uye hunhu hweparaffinic hwemapaipi ePE hunokanganisa kuunganidzwa kwemakomba egungwa ari kushanda.
Zvivakwa zveMagetsi
Nekuda kwekusapinza mvura kwakaderera kwePE, hunhu hwayo hwemagetsi hahunyanyi kukanganiswa nekusangana nemvura nguva dzose. Sezvo PE isiri polar hydrocarbon polymer, inodzivirira mvura zvakanyanya. Hunhu uhwu, zvisinei, hunhu hwacho hunogona kuipa zvakanyanya nekuda kwekusvibiswa, mhedzisiro ye oxidizing media kana mamiriro ekunze. Kudzivirira kwehuwandu hwemagetsi i>1017 Ωcm; simba re dielectric i220 kV/mm.
Nekuda kwekukura kwemagetsi anochaja, kungwarira kunokurudzirwa pakushandisa PE muzvishandiso apo njodzi yemoto kana kuputika inowanikwa.
CHUANGRONGikambani yakabatana muindasitiri yemasheya nekutengeserana, yakavambwa muna 2005 yakatarisana nekugadzirwa kweHDPE Pipes, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, uye kutengeswa kwePlastic Pipe Welding machines, Pipe Tools, Pipe Repair Clamp nezvimwewo.
