Kutanga kuisa pasi inodziya, mubvunzo unomuka kuti ndedzipi zvipunha zviri nani: yakakwenenzverwa polyethyle kana purasitiki.
Mhinduro iri mumamiriro ekushanda kwesimba rinodziya, uye mafungiro evano nyanzvi, ruzivo uye ongororo dzevanhu vanoshanda pasi rekudziya masisitimu vanozobatsira kubata nenyaya iyi.
Zvichida pombi dzese dzemazuva ano, dzakarongedzwa pombillene nhema, chete kuumbwa kwemapurasitiki emapurasitiki kune iyo yekunyepedzera-yakabatanidzwa polyethylen
Yakakwenenzverwa polyethyle: zvivakwa
Nekuda kwekuwedzera ma molecular zvisungo zvechitoro chakarukwa pombiyle ine simba rakanyanya
Yakatemwa Polyethyle inoreva zvinhu zvakakwirira-tech uye iri kugadzirwa kwePolymerization ye ethylene ine mesh mesh molecular chimiro nejira rejekiseni.
Mamiriro, maitiro ekurova ari kugadzira mamwe ma molecular tii. Iyo yekutanga polymer inosanganiswa neyakagwinha padanho remahara nemaoko emahara emamoreni, achigadzira grid nhatu-grid, chimwe chimiro chakasimba ne "memory interry".
Zvigadzirwa zvega-zvakagadzirirwa
Shanduko muhukuru uye chimiro chembiya pasi pesimba remitoro mushure mekubviswa kwavo kudzosa chigadzirwa mune yekutanga fomu. Sekureva kwehunyanzvi hwehunyanzvi, rex haina kuderera kune akawanda masosi uye anopfuura pasi pehupenyu hwebasa.
Yakarambidzwa pombillene pombi inogadzira nzira dzina:
- Iyo peroxide inounzwa muPolyethylene muOriferure yezvinyorwa. Dhigirii repamusoro rekuyambuka makumi manomwe neshanu muzana. Nenzira yeiyo yakaderera chigadzirwa uye yakakwira mutengo wechigadzirwa, asi zvinyorwa zvinova zvinogara zvakanaka uye zvakanyanyisa.
- Re -HB - Kugadziriswa kweNyuka neSilane uye Catalyst Kunogadzira Polyethyle, kubva pane iyo Shell yechigadzirwa isingakoshi, asi kana mvura yapera, inogona kumira zvakanyanya. Kurira ndeye 65%.
- Rech - c - Polymer akarapwa nemagetsi. Polyethyle ine yakaderera degree rekuyambuka 55 - 60%.
- RH - XD - Nitric acid inoshandiswa. Nzira yacho haiwanzo kushandiswa.
Yenzira dzakanyorwa, pombi yakagadzirwa nekushandiswa kweSilane inonyanya kudiwa, inoonekwa nemutengo wakakwana uye zvinogamuchirika zvivakwa.
Chinyorwa pane iyo nyaya: Kugadzirira kweiyo lime-based plaster
Iyo yakanyanya kusiyanisa pombi yeiyo inodziya pasi pePolyethylency yerimwe-loly-layer zvigadzirwa zveRex
Zvakanakira zvetsika dzakarongedzwa polyhyhyle zvigadzirwa
Iyo pombi kubva pane yakadaro zvinhu zvine musoro memusoro
Mapepa ekudziya anogadzirwa nenzira yeRe-ha uye re - xb ane hunhu:
- Kuramba kudzvinyirira kudonha. Mune yakanyanya kudzvinyirira maitiro, hupenyu hwezvigadzirwa hazvishanduke. Iyo polymer ndeyekumanikidza kumanikidza kusvika kune gumi mumhepo.
- Moremely ndangariro. Kana mvura ikatonhora mumupipi, iyo ice inokonzeresa inowedzera dhaya yeiyo pombi, uye mushure mekupaza chando, saizi yeiyo pombi inodzokera kune yekutanga shanduro, pasina kukuvadza zvinyorwa.
- Kunyungudika uye kupisa kupisa kwakanyanya. Zvinyorwa zvinouya zvichimhanya pakudziya kweanopfuura zana nemakumi mashanu c, uye kujekesa apo iyo ambure tembiricha inosvika mazana mana ° C.
- Kuramba makemikari uye biological. Iyo Polyethlene tube haina kuiswa pasi pekubatana, haigadziri mamiriro ezvinhu eFungsi uye kubereka mabhakitiriya, zvinhu zvinopesana nehuku nemvura isina kwayakarerekera.
- Kuchengetedza kwezvakatipoteredza. Izvo zvinyorwa panguva yekudziya hazviverengere zvinhu zvinokuvadza uye zvinokanganisa paCarbon dioxide uye mvura kana ichipfuta.
Polyethyle haatye kusiyana kwe tembiricha
- Purasitiki. Nekudzokororwa kwakadzokororwa, chigadzirwa hachina kuputika uye kudzoreredza kukura kweiyo bend.
- Kushanda. Iyo Polymer zvinhu zvinochengetedza zvivakwa, ramba usina kuchinjika mapipi saizi nekushisa tembiricha yekudzima kubva ku05 kusvika ku91 kusvika ku95.
Simbi Plastiki Tube: Zvivakwa
Zvakanakira kuyambuka-kuunganidzwa polyethyle ine zvakare simbi-yepurasitiki tube inosanganisira zvikamu zvishanu, imwe neimwe inoita mamwe mabasa. Iyo yekunze uye yemukati matare ePolymeric, uye iyo yekunze polyethylehy shell inoita kudzivirirwa kubva mukukuvara kwechimiro, uye iyo yemukati yakatsiga inotsvedza inopa kukurumidza kuyerera kwemvura.
Iyo yemukati yakatsiga layer haigadzi zvipingamupinyi zvemvura zvazvino
Kune maviri anonamatira zviyero pakati pePolymer zviyero, uye mukati - iyo yemukati denderedzwa sheath iyo inopa kuomarara kwezvigadzirwa zvesimbi-epurasitiki.
Kuvimbika uye kusavimbika mukuvhiya kwezvigadzirwa zvesimbi-epurasitiki zvinosarudza kunaka kweiyo mataira:
- Iyo aluminium layer yeiyo chigadzirwa inosarudza simba rayo uye inofanirwa kunge iri gobvu reinenge matatu mm. 2 Nzira dzekutyaira dzeAluminium layer inobata simba renyoka, Laser Welding mubatanidzwa uye Ultrasonic Welds inoshandiswa teko. Nzira yekuteerera jack yejle inodaidzwa seyasina kusununguka, haina kushayikwa kwekusagadzikana uye mukuenzanisa neWelding masheti haatenderi kubhururuka munzvimbo dzekubatana nemaitiro.
- Kunamatira kwakashandiswa kunosarudza bhuru rinokwanisika kwezvigadziko zvekushambadzira kupisa kweanotonhora, izvo zvinokanganisa simba renyepi. Pipi pombi yekucheka kana uchishandisa yakakwirira-mhando glue, bundle iri kushaikwa.
- Kuvimbika kwepombi kwakatemerwa nezvematemo emuranda, polymer ine pex uye pe-rt makafumari yemapipi, uye pombi ine imwe yekunyora inoshandiswa nemhando yepamhepo, mune ino nyaya, neiyo hydraulic murume.
Patinenge tichisarudza pombi yepurasitiki, tinofunga kuti izvi zvigadzirwa zvine nzira isina kusununguka yekufambisa aluminium layer, kupa iyo dambudziko-isina kuvhiringidza kushanda kwechigadzirwa.
Kusarudza mapipi emvura pasi
Edza kusarudza yakakwirira-mhando zvinhu
Proposials yakawanda uye nezve chigadzirwa, uye nezveMugadziri, mune ino chiitiko ndechekuti imwe, sarudzo yeiyo formula ndiyo mutengo wakanaka / mhando, asi zvinodikanwa kutanga nemhando:
- Pombi kuvimbika uye mashini simba kana ichishandiswa mune yakatarwa mamiriro, iyo ichave ichiratidza matambudziko ekushanda-kusarudzika kwehurongwa hwekushanda, i.e. Iyo pombi inofanira kumira nekumanikidzwa kweinenge gumi nembimbwa.
- Hupenyu hwebasa kana kujaira kwekushandiswa kwehurongwa hwekudziya hunodzika zvinoenderana nezvinogadzirwa izvo zvigadzirwa zvakagadzirwa nechigadzirwa. Kusvibiswa kwepombi hakubvumirwe pakudziya kweiyo inotonhorera 95 ° C.
- Yemahara mafambiro kuburikidza nepombi dzevapundu dzinotonhorera, iyo yemukati nzvimbo yeiyo pombi inofanira kunge yakatsetseka.
- Mamiriro ekugadzirisa, mitengo yebasa rekudzivirira uye kudzora bvunzo dzehurongwa hwekusimba kwakaringana. Verenga zvimwe nezve izvo mapepa ekusarudza, tarisa muvhidhiyo iyi:
Maitiro ekufananidza ehurongwa hwekudziya anopihwa nemusika, kuoma kwebasa rekuisa uye mamiriro ekushanda anoonekwa mushure mekuongorora hunhu hunhu. Chekupedzisira asi, isu tinofananidza mutengo wezvigadzirwa, kutora account yekuisa account, pamwe nekuomerwa neyakagadzirirwa kudziya pasi.

Esimbi mapurasitiki iri mashoma mapurasitiki zvichienzaniswa neCrosslinked Polyethylene
Izvo zvese zvakafanana, ndedzipi pombi iri nani kune inodziya pasi: polyethylene kana metalplastic. Musiyano wezvigadzirwa mune zvigadziko zveiyo yakayambuka polyethyle yeiyo simbi yepurasitiki pombi uye simbi yesimbi.
Kuvandudza Polymer, masayendisiti uye nyanzvi mumunda weChemistry akakwanisa kugadzirisa polyethylene ane zita remuchato pe - iyo iyo molecular chimiro chine mabendi ezvipfuyo. Iyo polymer haina kurasikirwa nezvivakwa zvayo mukudzokorora, kusiyana. Kurudziro yevanyanzvi mukusarudzwa kwe pombi uone muvhidhiyo iyi:
PIPME kubva PE - RT Polyethylene ine musoro wakasimba wekutonhora zvachose kuparadzaniswa ruzha rwekuyerera kwemvura. Iyo polymer yakanyanya kudarika iyo yakambomirirwa polyethlene kuramba kudzvinyirira uye tembiricha yeinotonhora, pamwe neiyo nguva yePombi.
Kutenda kune iyo Molecular chimiro nezvisungo zvemativi, iyo pepa yezvinhu inochengetedza TheRemoplasticasity, mapaipi anogona kutengeswa uye akashongedzwa pasina nzvimbo dzakanyadzisa.
Zvinyorwa zvinokatyamadza zvakati wandei chando uye thawing come kusashandura chimiro uye zvivakwa. Pe-rt zvinhu zvinoburitsa zvese polymeric zvigadzirwa uye simbi-plastiki.
Iyo yekupisa-inopesana ne - RT polymer mune yayo zvinhu zvakazara zvinosangana nezvinodiwa zvehusimbe uye zvinogona kutariswa sarudzo yakanaka kana uchisarudza mapipi.
