Uyini umehluko phakathi kwe-PE, PP, ABS?

I-wire plug impahla yentambo yamandla ihlanganisa ikakhulukaziI-PE (i-polyethylene), i-PP (i-polypropylene) ne-ABS (i-acrylonitrile-butadiene-styrene copolymer).

Lezi zinto zihlukile ngezakhiwo zazo, izinhlelo zokusebenza kanye nezici.
1. I-PE (i-polyethylene) :
(1) Izici: I-PE iyi-resin ye-thermoplastic, engenabuthi futhi engenabungozi, ukumelana nokushisa okuphansi, izakhiwo ezinhle kakhulu zokuvala ugesi nezinye izici. Iphinde ibe nezici zokulahlekelwa okuphansi namandla aphezulu okuqhuba, ngakho-ke ivame ukusetshenziswa njengempahla yokuvikela izintambo eziphezulu ze-voltage nekhebula. Ukwengeza, izinto ze-PE zinezici ezinhle zikagesi futhi zisetshenziswa kabanzi ezintanjeni ze-coaxial nezintambo ezidinga i-wire capacitance ephansi.
(2) Isicelo: Ngenxa yezindawo zayo ezinhle kakhulu zikagesi, i-PE ivame ukusetshenziswa ekufakeni izintambo noma ikhebula, i-data wire insulation material, njll. I-PE ingase futhi ithuthukise ukuncipha kwayo komlilo ngokungeza izinqamuleli zomlilo.

2. PP (i-polypropylene) :
(1) Izici: Izici ze-PP zifaka ukunwetshwa okuncane, akukho ukunwebeka, izinwele ezithambile, ukushesha kombala okuhle nokuthunga okulula. Nokho, ukudonsa kwayo kuncane kakhulu. Izinga lokushisa elisetshenziswayo le-PP lingu-30℃ ~ 80℃, futhi izici zalo zikagesi zingathuthukiswa ngokukhihliza amagwebu.
(2) Isicelo: Impahla ye-PP ifanele zonke izinhlobo zocingo nekhebula, njengentambo yamandla nocingo lwe-elekthronikhi, futhi ihlangabezana nezidingo ze-UL breaking force, ingaba ngaphandle kwamalunga.

3. I-ABS (acrylonitrile-butadiene-styrene copolymer) :
(1) Izici: I-ABS iyisakhiwo se-thermoplastic polymer esinamandla aphezulu, ukuqina okuhle nokucutshungulwa kalula. Inezinzuzo ze-acrylonitrile, i-butadiene kanye ne-styrene monomers amathathu, ukuze ibe nokumelana nokugqwala kwamakhemikhali, ukumelana nokushisa, ukuqina okuphezulu kwendawo kanye nokunwebeka okuphezulu nokuqina.
(2) Isicelo: I-ABS ivamise ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu kanye nokuqina, njengezingxenye zezimoto, izindawo ezivalekile zikagesi, njll. Ngokwezintambo zikagesi, i-ABS ivame ukusetshenziselwa ukwenza izivikela-mandla nezindlu.

Kafushane, i-PE, PP ne-ABS inezinzuzo zayo kanye nezimo zohlelo lokusebenza ezintweni zepulaki yezintambo zezintambo zikagesi. I-PE isetshenziswa kabanzi ekufakeni izintambo nokufakwa kwekhebula ngenxa yezakhiwo zayo ezinhle kakhulu zokufaka ugesi kanye nokumelana nezinga lokushisa eliphansi. I-PP ifaneleka ezinhlobonhlobo zezintambo nekhebula ngenxa yokuthambile kwayo nokushesha kombala okuhle; I-ABS, enamandla amakhulu kanye nokuqina kwayo, isetshenziselwa ukufaka izinto zikagesi nezintambo zikagesi ezidinga lezi zici.

Ungakhetha kanjani izinto ezifanele kakhulu ze-PE, PP kanye ne-ABS ngokuya ngezidingo zohlelo lwentambo yamandla?

Lapho ukhetha izinto ezifanele kakhulu ze-PE, PP kanye ne-ABS, kuyadingeka ukuthi ucabangele ngokuphelele izidingo zokusetshenziswa kwentambo yamandla.
1. Izinto ze-ABS:
(1) Izakhiwo zemishini: Impahla ye-ABS inamandla amakhulu nobulukhuni, futhi ingamelana nomthwalo omkhulu wemishini.
(2) Ukucwebezela okungaphezulu nokusebenza kokucubungula: Impahla ye-ABS inokucwebezela okuhle kwendawo nokusebenza kokucubungula, okulungele ukukhiqiza izindlu zezintambo zamandla noma izingxenye zepulaki ezinezidingo zokubukeka okuphezulu nokucutshungulwa okuhle.

2. Izinto ze-PP:
(1) Ukumelana nokushisa, ukuzinza kwamakhemikhali nokuvikelwa kwemvelo: Impahla ye-PP iyaziwa ngokumelana nokushisa okuhle, ukuzinza kwamakhemikhali nokuvikelwa kwemvelo.
(2) Ukufakwa kukagesi: I-PP ine-insulation kagesi enhle kakhulu, ingasetshenziswa ngokuqhubekayo ku-110 ℃-120 ℃, ifanele ungqimba lwangaphakathi lokufakelwa kolayini wamandla noma njengempahla ye-sheath yocingo.
(3) Izinkambu zokufaka isicelo: I-PP isetshenziswa kakhulu ezintweni zasendlini, ezimpakheni, ifenisha, emikhiqizweni yezolimo, emikhiqizweni yokwakha kanye neminye imikhakha, okubonisa ukuthi inokuhlukahluka kokusebenza nokwethembeka.

3, PE impahla:
(1) Ukumelana nokugqwala: Ishidi le-PE linokumelana okuhle kakhulu nokugqwala futhi lingahlala lizinzile emithonjeni yamakhemikhali efana ne-asidi ne-alkali.
(2) I-insulation kanye nokumuncwa kwamanzi aphansi: Ishidi le-PE line-insulation enhle kanye nokumuncwa kwamanzi aphansi, okwenza ishidi le-PE linesicelo esivamile emasimini kagesi kanye ne-elekthronikhi.
(3) Ukuguquguquka nomthelela wokumelana nomthelela: Ishidi le-PE libuye libe nokuguquguquka okuhle kanye nokumelana nomthelela, lifanele ukuvikelwa kwangaphandle kwentambo kagesi noma njengempahla ye-sheath yocingo ukuthuthukisa ukuqina nokuphepha kwayo.

Uma ulayini wamandla udinga amandla aphezulu kanye nesicwebezelisi esihle, impahla ye-ABS ingaba yisinqumo esingcono kakhulu;
Uma intambo kagesi idinga ukumelana nokushisa, ukuzinza kwamakhemikhali nokuvikelwa kwemvelo, impahla ye-PP ifaneleka kakhulu;
Uma intambo yamandla idinga ukumelana nokugqwala, ukwahlukanisa kanye nokumuncwa kwamanzi aphansi, impahla ye-PE iyisinqumo esihle.
