Izixhobo zentambo yombane: Isikhokelo sokukhetha i-PE ethintela ilangatye, i-PP ethintela ubushushu, kunye ne-ABS ethintela ilangatye

Kwimveliso yeentambo zombane, ukukhethwa kwezinto kuchaphazela ngokuthe ngqo ukhuseleko lombane, amandla oomatshini, kunye nobomi benkonzo. I-PE, i-PP, kunye ne-ABS zezona zinto zisetyenziswa kakhulu. I-PE kunye ne-PP zisetyenziswa kakhulu ekugqumeni nasekufakeni i-wire, ngelixa i-ABS isetyenziswa kakhulu kwiiplagi nakwiindawo zokubeka izinto.

I. PE (iPolyethylene)
PEsisixhobo sokukhusela iingcingo esiqhelekileyo esinokukhusela umbane okugqwesileyo, ukuguquguquka okuhle, ukumelana nobushushu obuphantsi, kunye nokufunxwa kwamanzi okuphantsi kakhulu. Sifanelekile ukusetyenziswa ixesha elide ukusuka kwi -40°C ukuya kwi-80°C, nto leyo eyenza ukuba silungele ukhuseleko lwangaphakathi lwentambo yombane. I-PE eqhelekileyo ayithinteli ilangabi (isalathisi se-oxygen 17–18) kwaye ifuna utshintsho oluthintela ilangabi (umz., nge-magnesium hydroxide okanye i-aluminium hydroxide) ukuze ihlangabezane nemigangatho yokhuseleko. I-PE isetyenziselwa iileya zokukhusela kwiintambo zombane, iintambo ze-elektroniki, kunye neentambo zedatha, kwaye ingasebenza njenge-cable sheathing ekhaphukhaphu. Ngokuqhelekileyo ayisetyenziselwa ii-plug housing.

II. I-PP (iPolypropylene)
I-PP iphumelela kakhulu kwi-PE ngokumelana nobushushu kunye namandla oomatshini. Amanqanaba aguquliweyo afikelela kumaqondo obushushu okusebenza ixesha elide ukusuka kwi-100°C ukuya kwi-105°C, kunye nokumelana okugqwesileyo kokugoba, ukumelana nokudinwa, kunye nozinzo lweekhemikhali. I-PP ifanelekile kwiintambo ze-elektroniki, iintambo zocingo, kunye neentambo zamandla zobushushu obuphakathi ukuya phezulu ezifuna ukumelana nobushushu obuphezulu kunye nokuqina. Njenge-PE, i-PP isetyenziswa kakhulu kwiifowuni. Ukuqina kwayo kunye namandla ayo okuchaphazeleka aphantsi kune-ABS, kwaye ukuncitshiswa kwayo okuphezulu kokubumba kwenza ukuba ingafaneleki kwiindawo zokufaka iiplagi.

III. ABS
I-ABS yiplastiki yobunjineli eyenzelwe ngokukodwa iiplagi zeentambo zombane kunye neendawo zokugcina. Idibanisa ukuqina, ukumelana nempembelelo, uzinzo olunemilinganiselo, kunye nokukhanya okuphezulu komphezulu, kunye nokukwazi ukusebenza kakuhle kokubumba ngenaliti. I-ABS eqhelekileyo iyatsha (isalathisi seoksijini simalunga ne-18), ngoko ke i-ABS ethintela ilangatye edibana ne-UL 94 V-0 okanye i-V-2 iyadingeka kwizicelo zeentambo zombane. I-ABS ayifanelekanga kwi-insulation yentambo kwaye isetyenziselwa kuphela izinto zeplastiki zangaphandle.

IV. Iingcebiso zoKhetho
I-PE: Kwimigca yokwambathisa kwiintambo zombane, iingcingo ze-elektroniki, kunye neengcingo zedatha ezifuna ukusebenza okuphezulu kokwambathisa kunye nokuguquguquka. Kufuneka kusetyenziswe i-PE eguqulweyo ethintela ilangabi.
I-PP: Kwiintambo ze-elektroniki, iintambo zocingo, kunye neentambo zamandla ezishushu kakhulu neziphakathi ukuya phezulu ezifuna ukumelana nobushushu obuphezulu kunye nokumelana nokugoba.
I-ABS ethintela ilangatye: Kwiziplagi, iindawo zokugcina iadaptha, iikliphu zekhebula, kunye nezinye izinto zokwakha. Khetha i-ABS ehlangabezana novavanyo lwe-UL 94 oluthintela ilangatye.
Ukukhethwa kwezinto ezifanelekileyo kuqinisekisa ukhuseleko olufanelekileyo, ukuqina, kunye nokubonakala kweentambo zombane.

Isiphelo
IHLABATHI ELINYEIngcali ekunikezeni i-PE eguqulweyo ethintela umlilo, i-PP engatshisi ubushushu, kunye ne-ABS engatshisi umlilo kwizicelo zeentambo zombane, inikezela ngezisombululo ezenzelwe wena kunye nenkxaso yobugcisa. Ukuze ufumane iingcebiso zokukhetha, uvavanyo lweesampulu, okanye iikowuteshini, nceda unxibelelane nathi.
