Uyini umehluko phakathi kwe-PE, PP, ABS?

Izinto ezifakiwe zentambo yentambo yamandla zifaka ikakhulukaziI-PE (polyethylene), PP (Polypropylene) kanye ne-AB (acrylonitritre-buthadieene-styrene copolymer).

Lezi zinto zokwenziwa ziyehluka ezicini zazo, izinhlelo kanye nezimpawu.
1. I-PE (polyethylene) :
(1) Izici: I-PE iyi-resin ye-thermoplastic, enobuthi obungelona ubungozi futhi obungenabungozi, ukumelana okuphansi, izindawo zokufakwa kakhulu ngogesi ezifakiwe nezinye izici. Iphinde ibe nezimpawu zokulahlekelwa okuphansi kanye namandla aphezulu aphaselayo, ngakho-ke kuvame ukusetshenziswa njengento yokufaka i-voltage wire nentambo. Ngaphezu kwalokho, izinto ze-PE zinezimpawu ezinhle zikagesi futhi zisetshenziswa kabanzi kwizintambo ze-coaxial kanye namakhebuli adinga ukukhonkotha kwentambo ephansi.

2. I-PP (Polypropylene):
(1) Izici: Izici ze-PP zifaka phakathi ukugcwala okuncane, akukho ukuqina, izinwele ezithambile, ukushesha kombala okuhle nokuthunga okulula. Kodwa-ke, ukudonsa kwalo kumpofu. Uhla lokushisa lokusebenzisa lwe-PP lungu-30 ℃ ~ 80 ℃, kanye nezimpawu zalo zikagesi zingathuthukiswa ngegwebu.
(2) Isicelo: Izinto ze-PP zilungele zonke izinhlobo zocingo nekhebula, njengentambo yamandla kanye ne-elektroniki, futhi zihlangabezana nezidingo ze-Ul Breaking Force, zingaba ngaphandle kwamalunga.

3. I-ABS (i-acrylonitritre-buthadiene-styrene copolymer):
(1) Izici: I-ABS yisakhiwo sezinto ezibonakalayo ze-polymer ezinamandla aphezulu, ubulukhuni obuhle nokucutshungulwa okulula. Inezinzuzo ze-acrylonitrile, i-batadiene kanye ne-styrene ezintathu amamomor amamomor, ukuze ihlukane nokugqwala kwamakhemikhali, ukumelana nokushisa, ubulukhuni obuphezulu nobunzima obuphezulu nobunzima.
(2) Isicelo: I-ABS imvamisa isetshenziswa kuzinhlelo zokusebenza ezidinga amandla aphezulu kanye nobunzima, njengezingxenye ze-auto, ukufakwa kukagesi, njll. Ngokuvamile izintambo zamandla, i-AB ivame ukusetshenziselwa ukukhiqiza ama-insulators kanye nezindlu.

Ngamafuphi, i-PE, i-pp kanye ne-abs zinezinzuzo zazo kanye nezimo zohlelo lokusebenza ezintweni zokwenziwa kwamakhebuli wamandla. Isetshenziswa kabanzi ku-wire kanye nentambo yokufakwa kwentambo yezakhiwo zayo zokufakwa kukagesi ezinhle kakhulu kanye nokumelana okuphansi kwezinga lokushisa. I-PP ilungele izinhlobo ezahlukahlukene zocingo nentambo ngenxa yokuthamba kwayo nokushesha kombala okuhle; I-ABS, ngamandla ayo aphezulu kanye nobunzima, isetshenziselwa ukufaka izingxenye zikagesi kanye nemigqa yamandla adinga lezi zici.

Ungayikhetha kanjani i-PE, i-PP kanye nezinto zokwakha ngokuya ngezidingo zohlelo lokusebenza lwamandla?

Lapho ukhetha izinto ezifaneleke kakhulu ze-PE, i-PP kanye nezinto zokwakha, kuyadingeka ukuze ubheke ngokugcwele izidingo zesicelo sentambo yamandla.
1. I-ABS Material:
(1) Izakhiwo zemishini: Izinto ze-ABS zinamandla amakhulu nobulukhuni, futhi zingamelana nemithwalo emikhulu emishini.
.

2. Izinto ze-PP:
(1) Ukumelana nokushisa, ukuqina kwamakhemikhali nokuvikelwa kwemvelo: Izinto ze-PP zaziwa ngokumelana kwayo okuhle kokushisa, ukuqina kwamakhemikhali nokuvikelwa kwemvelo.

.

3, PE impahla:
(1) Ukumelana nokugqwala: Ishidi le-PE linokumelana okuhle kakhulu kokugqwala futhi lingahlala lizinzile kwabezindaba zamakhemikhali njenge-acid ne-alkali.
.
(3) Ukuguquguquka nokumelana nomthelela

Uma umugqa wamandla udinga amandla aphezulu kanye ne-gloss enhle engaphezulu, izinto ezibonakalayo zingaba yisinqumo esihle kakhulu;
Uma umugqa wamandla udinga ukumelana nokushisa, ukuqina kwamakhemikhali nokuvikelwa kwemvelo, impahla ye-PP ifaneleke kakhulu;
Uma ulayini wamandla udinga ukumelana nokugqwala, ukufakwa kanye nokufakwa kwamanzi okuphansi, izinto ze-PE ziyinketho efanelekile.
