Njengempahla, iwebhu idlala indima ebalulekile ekusetshenzisweni okuhlukahlukene. Ivamise ukusetshenziswa ezimbonini zokuqwala izintaba/zokukanisa, ngaphandle, ezempi, ezifuywayo kanye nezimboni zezimpahla zemidlalo. Kodwa yini eyenza izinhlobo ezahlukene zewebhu zigqame? Ake sixoxe ngomehluko phakathi kwe-polypropylene, i-polyester ne-nylon webbing.

Itheyiphu ye-polypropylene yewebhu
I-polypropylene webbing yenziwe nge-thermoplastic synthetic polymer eyaziwa ngokuhlala kwayo isikhathi eside, amandla, nokumelana namanzi. Iwuwebhu engabizi kakhulu engamelana nezimo zezulu ezinzima futhi iguquguquka kakhulu. Ivamise ukusetshenziswa emishinini yangaphandle ngenxa yokuvikela kwayo okuhle kwe-UV kanye nokumelana nesikhutha. I-polypropylene webbing ayithinteki ngamafutha, amakhemikhali nama-asidi. Kodwa-ke, ayinconyelwe ukwenza umsebenzi osindayo wewebhu ngenxa yezinga layo eliphansi lokuncibilika.

Itheyiphu ye-polyester yewebhu
I-polyester webbing iyinketho ethandwa kakhulu yewebhu ngoba inamanzi amaningi, isikhutha futhi imelana ne-UV. Kuyimpahla eqinile futhi eqinile ekwazi ukumelana nokukhanya kwelanga, imihuzuko kanye nesimo sezulu esibi. I-polyester webbing iyisinqumo esihle kakhulu sokusebenzisa ngaphandle, ojosaka, nebhande lemithwalo ngoba ingamelana nezinga lokushisa elidlulele (-40°F kuya ku-257°F). Yize ingenamandla njengenayiloni, isengenye yezinketho ezidume kakhulu ngoba iyathengeka futhi iza ngezinhlobonhlobo zobubanzi nezitayela ezihambisana nezidingo zakho.

itheyiphu ye-nylon yewebhu
Ulwembu lwenayiloni lwenziwa ngemicu yenayiloni eyaziwa ngamandla ayo, ukuqina, kanye nokumelana nokuhuzuka okuphezulu. Ingakwazi ukumelana nemithwalo esindayo, izimo zezulu ezimbi kanye namakhemikhali. Lokhu kwenza ulwembu lwenayiloni lube yimpahla efanelekile yokwakha impahla yezempi, amahhanisi namabhande. Iwebhu enayiloni ayifani nezinhlelo zokusebenza ezihuzuka kakhulu, kodwa ayivimbeli amanzi njenge-polypropylene noma i-polyester webbing. Inayiloni kuseyisinqumo esihle sewebhu yangaphandle ngenxa yamandla ayo aqinile—ayinqamuki noma inqamuke njengezinye izinto.

Ukukhethwa kwempahla yewebhu efanele kuncike kuhlelo lokusebenza oluthile. Iwebhu ye-polypropylene ilungele izinhlelo zokusebenza ezinomkhawulo, kuyilapho i-polyester webbing iyisinqumo esihle kakhulu sokusebenzisa ngaphandle, futhi uma ufuna amandla aphezulu nokuqina, i-nayiloni yewebhu iyisinqumo esingcono kakhulu.
