Yintoni umahluko phakathi kwe-PE, PP, ABS?

Isixhobo seplagi yocingo yentambo yamandla ibandakanya ikakhuluI-PE (i-polyethylene), PP (polypropylene) kunye ne-ABS (acrylonitrile-butadiene-styrene copolymer).

Ezi zixhobo zihluke kwiipropati zabo, izicelo kunye neempawu.
1. I-PE (i-polyethylene) :
(1) Iimpawu: I-PE i-resin ye-thermoplastic, ene-non-toxic kwaye ingenabungozi, ukumelana nobushushu obuphantsi, iimpawu ezigqwesileyo zombane kunye nezinye iimpawu. Ikwanayo neempawu zelahleko ephantsi kunye namandla aphezulu okuqhuba, ke isoloko isetyenziswa njengesixhobo sokugquma amacingo ombane aphezulu kunye nentambo. Ukongezelela, izinto ze-PE zineempawu ezintle zombane kwaye zisetyenziswa ngokubanzi kwiintambo ze-coaxial kunye neentambo ezifuna i-wire capacitance ephantsi.

2. PP (ipolypropylene) :
(1) Iimpawu: Iimpawu zePP ziquka ubude obuncinci, akukho ukuqina, iinwele ezithambileyo, ukukhawuleza kombala kunye nokuthunga okulula. Nangona kunjalo, umtsalane wayo uphantsi. Uluhlu lobushushu bokusetyenziswa kwePP yi -30 ℃ ~ 80 ℃, kwaye iimpawu zayo zombane zinokuphuculwa ngokukhupha amagwebu.
(2) Isicelo: Izinto zePP zifanelekile zonke iintlobo zocingo kunye nekhebula, njengentambo yamandla kunye nocingo lwe-elektroniki, kwaye ihlangabezana neemfuno ze-UL yokuphulwa kwamandla, ingaba ngaphandle kwamalungu.

3. I-ABS (i-acrylonitrile-butadiene-styrene copolymer) :
(1) Iimpawu: I-ABS sisakhiwo se-thermoplastic polymer esinamandla amakhulu, ukuqina okulungileyo kunye nokuqhuba lula. Ineenzuzo ze-acrylonitrile, i-butadiene kunye ne-styrene monomers ezintathu, ukuze ibe nokumelana nokubola kweekhemikhali, ukumelana nobushushu, ubunzima obuphezulu kunye nokuqina okuphezulu kunye nokuqina.
(2) Isicelo: I-ABS idla ngokusetyenziswa kwizicelo ezifuna amandla aphezulu kunye nokuqina, njengamacandelo e-auto, i-enclosures zombane, njl. Ngokweentambo zombane, i-ABS isoloko isetyenziselwa ukuvelisa i-insulators kunye nezindlu.

Isishwankathelo, i-PE, i-PP kunye ne-ABS ineenzuzo zabo kunye neemeko zesicelo kwizinto zeplagi zocingo zeentambo zamandla. I-PE isetyenziswa ngokubanzi kwi-insulation ye-wire kunye ne-cable ngenxa yeempawu zayo ezigqwesileyo zombane kunye nokumelana nokushisa okuphantsi. I-PP ifanelekile kwiindidi ezahlukeneyo zocingo kunye nekhebula ngenxa yokuthamba kwayo kunye nokukhawuleza kombala; I-ABS, enamandla amakhulu kunye nokuqina kwayo, isetyenziselwa ukugquma izixhobo zombane kunye neentambo zamandla ezifuna ezi mpawu.

Indlela yokukhetha izinto ezifanelekileyo ze-PE, PP kunye ne-ABS ngokweemfuno zesicelo sentambo yamandla?

Xa ukhetha izinto ezifanelekileyo ze-PE, PP kunye ne-ABS, kuyimfuneko ukuqwalasela ngokubanzi iimfuno zesicelo sentambo yamandla.
1. Izinto ze-ABS:
(1) Iimpawu zoomatshini: Izinto ze-ABS zinamandla amakhulu kunye nobunzima, kwaye ziyakwazi ukumelana nomthwalo omkhulu womatshini.
(2) Iglosi yomphezulu kunye nokusebenza kokusebenza: Isixhobo se-ABS sineglosi elungileyo yomphezulu kunye nokusebenza kokusetyenzwa, esilungele ukwenziwa kombane wendlu okanye iinxalenye zeplagi ezineemfuno zenkangeleko ephezulu kunye nokulungiswa kakuhle.

2. Izinto zePP:
(1) Ukumelana nokushisa, ukuzinza kweekhemikhali kunye nokukhuselwa kwendalo: Izinto zePP ziyaziwa ngokumelana nokushisa kakuhle, ukuzinza kweekhemikhali kunye nokukhuselwa kwendalo.
(2) Ukugquma kombane: I-PP ine-insulation yombane egqwesileyo, ingasetyenziswa ngokuqhubekayo kwi-110 ℃-120 ℃, ifanelekile kuluhlu lwangaphakathi lomgca wombane okanye njengento ye-sheath yocingo.
(3) Iinkalo zesicelo: I-PP isetyenziswa ngokubanzi kwizixhobo zendlu, ukupakisha iimpahla, ifenitshala, iimveliso zezolimo, iimveliso zokwakha kunye nezinye iinkalo, ezibonisa ukuba inoluhlu olubanzi lokusetyenziswa kunye nokuthembeka.

3, izinto ze-PE:
(1) Ukunganyangeki kwe-Corrosion: Iphepha le-PE linokumelana nokugqwesa okugqwesileyo kwaye linokuhlala lizinzile kumajelo eendaba amachiza afana ne-asidi kunye ne-alkali.
(2) I-Insulation kunye ne-low water absorption: I-PE sheet ine-insulation efanelekileyo kunye ne-low water absorption, ukwenza i-PE sheet inesicelo esiqhelekileyo kwiindawo zombane kunye ne-elektroniki.
(3) Ukuguquguquka kunye nokuchasana kwempembelelo: Iphepha le-PE libuye libe nokuguquguquka okulungileyo kunye nokuchasana kwempembelelo, ilungele ukukhuselwa kwangaphandle kwentambo yamandla okanye njengento ye-sheath yocingo ukuphucula ukuhlala kwayo kunye nokhuseleko.

Ukuba umgca wamandla ufuna amandla aphezulu kunye neglosi elungileyo, izinto ze-ABS zinokuba lolona khetho lungcono;
Ukuba umgca wamandla ufuna ukumelana nobushushu, ukuzinza kweekhemikhali kunye nokukhuselwa kwendalo, izinto zePP zifanelekile ngakumbi;
Ukuba umgca wamandla ufuna ukuxhathisa ukubola, ukugquma kunye nokufunxa kwamanzi aphantsi, izinto ze-PE lukhetho olufanelekileyo.
