Izinto Zentambo Kagesi: Umhlahlandlela Wokukhetha i-PE Evimbela Umlilo, i-PP Emelana Nokushisa, kanye ne-ABS Evimbela Umlilo

Ekukhiqizweni kwezintambo zikagesi, ukukhethwa kwezinto kuthinta ngqo ukuphepha kukagesi, amandla omshini, kanye nempilo yesevisi. I-PE, i-PP, kanye ne-ABS yizinto ezintathu ezisetshenziswa kakhulu. I-PE kanye ne-PP zisetshenziswa kakhulu ekugqumeni nasekuvaleleni ucingo, kuyilapho i-ABS isetshenziswa kakhulu kuma-plug kanye nama-housings.

I. PE (i-Polyethylene)
PEiyinto yokuvikela izintambo yakudala enokuvikela okuhle kakhulu kukagesi, ukuguquguquka okuhle, ukumelana nokushisa okuphansi, kanye nokumuncwa kwamanzi okuphansi kakhulu. Ifanele ukusetshenziswa isikhathi eside kusukela ku--40°C kuya ku-80°C, okwenza ibe yindawo efanele yokuvikela izintambo zikagesi zangaphakathi. I-PE ejwayelekile ayivimbeli ilangabi (inkomba ye-oxygen 17–18) futhi idinga ukuguqulwa kokuvimbela ilangabi (isb., nge-magnesium hydroxide noma i-aluminium hydroxide) ukuze ihlangabezane nezindinganiso zokuphepha. I-PE isetshenziselwa izendlalelo zokuvikela izintambo zikagesi, izintambo zikagesi, kanye nezintambo zedatha, futhi ingasebenza futhi njenge-sheathing yekhebula elula. Ngokuvamile ayisetshenziswa ezindlini zamapulagi.

II. I-PP (i-Polypropylene)
I-PP idlula i-PE ngokumelana nokushisa kanye namandla omshini. Amabanga aguquliwe afinyelela amazinga okushisa okusebenza esikhathi eside angu-100°C kuya ku-105°C, ngokumelana okuhle kakhulu kokugoba, ukumelana nokukhathala, kanye nokuqina kwamakhemikhali. I-PP ifaneleka kahle izintambo zikagesi, ama-wiring harnesses, kanye nezintambo zikagesi ezishisa kakhulu neziphakathi kuya kweziphezulu ezidinga ukumelana nokushisa okuphezulu kanye nokuqina. Njenge-PE, i-PP isetshenziswa kakhulu ekusetshenzisweni kwezintambo. Ukuqina kwayo kanye namandla ayo okushaya kuphansi kune-ABS, futhi ukuncishiswa kwayo okuphezulu kwesikhunta kwenza ingafaneleki ezindlini zokufaka amapulagi.

III. I-ABS
I-ABS iyipulasitiki yobunjiniyela eklanyelwe ngqo ama-plug entambo kagesi kanye nezindawo zokubopha. Ihlanganisa ukuqina, ukumelana nokushayisana, ukuzinza kobukhulu, kanye nokukhanya okuphezulu kobuso, kanye nokucutshungulwa kokubunjwa komjovo okuphezulu. I-ABS ejwayelekile iyavutha (inkomba ye-oxygen cishe i-18), ngakho-ke i-ABS evimbela ilangabi ehlangabezana nezilinganiso ze-UL 94 V-0 noma i-V-2 iyadingeka ekusetshenzisweni kwentambo kagesi. I-ABS ayifaneleki ukuvikela intambo futhi isetshenziselwa kuphela izingxenye zepulasitiki zangaphandle.

IV. Izincomo Zokukhetha
I-PE: Kwezendlalelo zokufaka izinto ezintanjeni zikagesi, izintambo zikagesi, kanye nezintambo zedatha ezidinga ukusebenza okuphezulu kokufaka izinto ezintanjeni kanye nokuguquguquka. I-PE eguquliwe evimbela ilangabi kumele isetshenziswe.
I-PP: Ngezintambo zikagesi, ama-wiring harnesses, kanye nezintambo zikagesi ezishisa kakhulu neziphakathi kuya kweziphezulu ezifuna ukumelana nokushisa okuphezulu kanye nokumelana nokugoba.
I-ABS Evimbela Umlilo: Yezixhumi, izindawo zokugcina i-adaptha, iziqeshana zekhebula, nezinye izingxenye zesakhiwo. Khetha i-ABS ehlangabezana nezilinganiso ze-UL 94 ezivimbela umlilo.
Ukukhetha izinto ezifanele kuqinisekisa ukuphepha okuhle, ukuqina, kanye nokubukeka kwezintambo zikagesi.

Isiphetho
IZWE ELILODWAigxile ekuhlinzekeni nge-PE eguquliwe evimbela ilangabi, i-PP engashisi, kanye ne-ABS evimbela ilangabi yezinhlelo zokusebenza zezintambo zikagesi, inikeza izixazululo ezenzelwe wena kanye nokusekelwa kobuchwepheshe. Ukuze uthole iseluleko sokukhetha, ukuhlolwa kwesampula, noma izingcaphuno, sicela uxhumane nathi.
