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 nakwii-housings.

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.
