Umehluko wokusebenza phakathi kwepuleti yepuleti nepuleti

Ipuleti ye-PE luhlobo lwe-thermoplastic resin ene-crystaltity ephezulu ne-non-polarity. Ukubonakala kwe-PE yoqobo kumhlophe okumhlophe, futhi kuguqulwa ngezinga elithile esigabeni esincanyana.

Ipuleti le-PE linokumelana kahle namakhemikhali amaningi asekhaya nawezimboni. Izinhlobo ezithile zamakhemikhali zingadala ukugqwala kwamakhemikhali, njenge-oxirical axidants (i-nitric acid), ama-hydrocarbons amnandi (i-xylene) nama-hydrocarbons (i-carbon tetrachloride). I-polymer ayimukeli umswakama futhi inokuphikiswa okuhle kwe-vapor yamanzi, futhi ingasetshenziselwa izinhloso zokupakisha. I-PE inezindawo ezinhle zikagesi, ikakhulukazi amandla aphezulu we-dielectric, okwenza kulungele izintambo namakhebuli. I-Medium to High Molecular Might Magazine inokumelana kahle nomthelela omuhle kakhulu, noma ngabe kushifu lokushisa lasekamelweni kanye - namazinga okushisa aphansi angama-40m. Izici eziyingqayizivele zePe yamabanga ahlukahlukene zihlanganiswa kahle kwezinto ezine ezilinganayo: Ubuningi, isisindo se-molecular, ukusatshalaliswa kwesisindo kwamangqamuzana kanye nezithasiselo. Ama-catalysts ahlukene asetshenziselwa ukukhiqiza ama-polymers ahleliwe ngezakhiwo ezikhethekile. Lezi zinhlobonhlobo zihlanganiswe ukukhiqiza amamaki we-PE ngezinhloso ezihlukile futhi kufinyelelwe ibhalansi engcono kakhulu ekusebenzeni. Inokuqina okuhle kwamakhemikhali futhi ingamelana nokuguguleka kwe-acid, i-alkali, isixazululo se-organic namanzi ashisayo. Ukufakelwa ngogesi kuhle.

Iphoyinti lokuncibilika kweshidi le-PE lingaba ngu-130 ℃, kanye nobuningi obuhlobene ngu-0.941-0.960. Inokumelana nokulimala okuhle nokuphikiswa okubandayo, ukuqina okuhle kwamakhemikhali, ubulukhuni obukhulu nobunzima, namandla amahle omshini. Izakhiwo ze-dielectric kanye nokuphikiswa kwengcindezi yemvelo nakho kuhle. Izinga lokushisa elincibilikayo lisuka ku-220 ℃ kuya ku-260 ℃. Okwezinto zokwenziwa ngosayizi omkhulu we-molecule, uhla lokushisa oluncibilikayo luphakanyiswa ukuba phakathi kwama-200 no-250 ℃.

Ipuleti le-POM, elaziwa ngokuthi i-Delrin Plate, likhishwe yizinhlayiya zepulasitiki nge-extruder ekushiseni okuphezulu, ngokukhishwa okufayo okufayo ukuthola amapuleti wobukhulu obuhlukile. Kuyipulasitiki yobunjiniyela be-thermoplastic enendawo ephezulu yokuncibilika kanye ne-crystaltaltity ephezulu. Ngenxa yezimpawu ezinhle zepuleti le-pom, ilungele kakhulu imishini ye-othomathikhi ye-lathe, ikakhulukazi yokukhiqiza izingxenye ezinembile.

Ipuleti le-POM luhlobo lwe-copolymer ngaphandle kwe-side chain, ubukhulu obuphakeme kanye ne-crystaltaltity ephezulu. Inezakhiwo ezinhle kakhulu ezibanzi.

Ipuleti le-POM luhlobo lwezinto ezinzima nezihlangene ezinendawo ebushelelezi ne-luster. Kumnyama noma kumhlophe futhi kungasetshenziselwa isikhathi eside ebangeni lokushisa le-40 - 106 degree ℃. Ukumelana kwayo ukugqokwa nokuzithambisa kuphakeme futhi kunamapulasitiki amaningi wobunjiniyela. Iphinde ibe nokumelana kahle kawoyela nokumelana kwe-peroxide. Kuyinto engamelana ne-acid, i-alkali-engamelana ne-ultraviolet radiant engavikeli.

I-POM iyipulasitiki ye-crystalline enendawo esobala yokuncibilika. Lapho iphuzu lokuncibilika selifinyelelwe, ukuncibilika ukuncibilika kuncipha ngokushesha okukhulu. Lapho izinga lokushisa lidlula umkhawulo othile noma ukuncibilika kufudunyezwa isikhathi eside kakhulu, kuzokubangela ukubola.
