Uyini umehluko phakathi kwe-polyethylene ene-chlorine ephezulu kanye nerabha ene-chlorine?

I-polyethylene ene-chlorine ephezulu (HCPE) kanye nerabha ene-chlorine (CR) ekhiqizwa yiBontecn Group China yi-polymers ezimbili ezisetshenziswa kabanzi emikhakheni yezingubo zokunamathela kanye ne-adhesive ezilwa nokugqwala, kodwa zinomehluko omkhulu ekwakhiweni kwamakhemikhali, izici zokusebenza, kanye nezimo ezifanele.
1. Isakhiwo samakhemikhali kanye nobungani bemvelo
I-HCPE: Ilungiselelwe ngokuguqulwa kwe-chlorination ye-polyethylene, ngokusatshalaliswa okungahleliwe kwama-athomu e-chlorine kanye nokuqukethwe kwe-chlorine okuvame ukuba yi-≥ 65%. Ekhiqizwa ngendlela yokumiswa kwamanzi, ayinayo ingcoliso ye-solvent futhi ihlangabezana nezidingo zokuvikela imvelo.
CR: Kwenziwa ngokufaka i-chlorine erabheni yemvelo noma irabheli yokwenziwa, enokuqukethwe kwe-chlorine okungaba ngu-60-65%. Ukukhiqizwa kwesinyibilikisi sendabuko kungabangela izinto eziyingozi ezisele kanye nokuvikelwa okungekuhle kwemvelo.
2. Ukuqhathaniswa kokusebenza
Ukumelana nesimo sezulu: I-HCPE inokumelana okuphezulu kwe-ozone kanye ne-ultraviolet, okwenza ifanelekele izindawo zokuchayeka ngaphandle isikhathi eside njengamabhuloho nemikhumbi; i-CR ithambekele ekuwohlokeni emazingeni okushisa aphezulu futhi inokumelana nesimo sezulu okubuthakathaka.
Ukumelana namakhemikhali: Zombili zimelana ne-asidi kanye ne-alkali, kodwa i-HCPE ibekezelela kakhulu ama-oxidant aqinile (njenge-sulfuric acid egxilile), ngaphandle kokuqhuma noma ukuchitheka ngemva kwezinsuku ezingu-30 zokuhlolwa.
3. Umehluko emasimini ohlelo lokusebenza
I-HCPE:
Isimbozo esinzima sokulwa nokugqwala (imishini yamakhemikhali, amapayipi e-oyela)
Izinto ezivimbela ilangabi (izembozo ezingashi, ama-cable sheaths)
Ingcina ephezulu (yokubopha nge-PVC nensimbi)
I-CR:
Izembozo zendabuko zokulwa nokugqwala (zemikhumbi nezitsha)
Inkambu ye-inki kanye nokuphrinta
4. Imakethe kanye Nezindleko
I-HCPE: Ngenxa yezindleko eziphakeme zezinqubo ezinobungani nemvelo kodwa ukusebenza okungcono kakhulu, kancane kancane ithatha indawo ye-CR.
CR: Intengo iphansi, kodwa ngenxa yemithethonqubo yezemvelo, ububanzi bokusetshenziswa bunqunyelwe.
5. Ukusetshenziswa okusekelayo
Zombili ziyahambisana nezinye izinhlayiya ezifana ne-epoxy resin kanye ne-acrylic acid, kodwa i-HCPE ifaneleka kakhulu ezinhlelweni zokumboza ezihlanganisiwe ezidinga ukunamathela okuphezulu noma ukumelana nesimo sezulu.
