Polyester vs. Nylon Flat Slings: Tiprofayile ta ku lwisana na tikhemikhali na ku leha

Ku hlawula exikarhi ka polyester flat sling na nylon flat sling ahi mhaka ya leswaku yin'wana yi 'better' kutlula yin'wana—swiya hiku hetiseka hi ndzhawu ya xitirhisiwa. Switirhisiwa leswi haswimbirhi swi avelana swipimelo swofana swa ndzhwalo wo tirha xikan’we na mahiselo (-40°C kuya eka 100°C) ehansi ka EN 1492-1 , kambe swihambana swinene eka ku leha, ku lwisana na ti khemikhali, na nhlamulo ya ndzhongho. Nylon yi anama 6–10% eka ndzhwalo lowu ringanyetiweke naswona yi lwisana na ti alkali kambe yi onhiwa hi ti acids . Polyester yi anama ntsena 3–4% naswona yi lwisana na ti acid kambe yi onhiwa hi ti alkalis . Nkongomiso lowu wu nyika ku pimanisiwa hi vuxokoxoko ku pfuna vanjhiniyara na vatirhi va rigging ku hlawula switirhisiwa swa flat sling leswi faneleke eka swiyimo swa vona swo karhi swa ntirho.

Fizikisi Ya Swirhendzevutana Swa Xiphepherhele: Ndlela Leyi Swiphemu Leswi Anamaka Swi Pfuxetaka Ntshikelelo Ni Ku Sirhelela Ndzhwalo Ha Yona

Xirhendzevutana lexi nga ni xiphepherhele a xi koti ku tlakusa ndzhwalo ntsena—xi wu sirhelela. Vuandlalo byo anama, bya xiphepherhele bya webbing byi hangalasa ntiko wa ndzhwalo eka ndzhawu leyikulu, leswi hungutaka swinene ntshikelelo eka ndzhawu yin’wana na yin’wana. Lowu i nsinya wa xisekelo wa fizikisi endzhaku ka swirhendzevutani swa xiphepherhele: Ntshikelelo = Matimba ÷ Ndhawu. Hi ku engetela ndhawu leyi ku hlanganaka eka yona, swirhendzevutana leswi nga ni swiphepherhele swi hunguta khombo ra ku onhaka ka le henhla, ku tshoveka ni ku pfotlosiwa—leswi swi endlaka leswaku swi va xihlawuhlawu lexi rhandzekaka xo tlakusa swilo leswi nga ni vuxiyaxiya, leswi hetiweke kumbe leswi onhakeke hi ku olova. Nkongomiso lowu wu hlamusela physics ya ku hangalasiwa ka ntshikelelo, wu pimanisa swirhendzevutani swa flat na swintshuxo swin’wana swo tlakusa, naswona wu nyika nkongomiso lowu tirhaka wo hlawula ku anama ka sling loku faneleke eka xitirhisiwa xa wena.

Hi wihi Nawu wa 1/10 wo tshika ku tirhisa Flat Sling?

Nawu wa 1/10 i criterion yo kongoma kambe ya nkoka swinene ya retirement eka ti flat slings: loko abrasive wear yi hunguta ku anama ka webbing hi 1/10 kumbe kutlula, sling yifanele ku susiwa eka ntirho. Nawu lowu wu boxiwile eka EN 1492-1 naswona wu amukeriwile hi ASME B30.9 tanihi xikombiso xa nkoka xa ku ambala ngopfu. Nkongomiso lowu wu hlamusela leswi nawu wa 1/10 wu vulaka swona, ndlela yo pima ku anama ka webbing hi ku kongoma, leswaku hikokwalaho ka yini threshold leyi yi hlawuriwile, na ndlela yo yi tirhisa eka ku kamberiwa ka siku na siku. Eka valanguteri va rigging na vativi va vuhlayiseki, ku twisisa nawu lowu wo olova swi nga sivela ku tirhisiwa ka swirhendzevutani leswi ambaleke hi ndlela leyi nga na khombo.

Xana Sling Angle Yi Khumba Njhani Vuswikoti Bya Flat Sling?

Flat sling leyi ringanyetiweke eka 2 tons eka straight vertical lift yinga kota ntsena ku tlakusa 1 ton hiku hlayiseka loko yitirhisiwa eka 60° angle. Leswi swi vangiwa hileswi angle ya sling yi khumbaka hi ku kongoma tension eka nenge wun’wana na wun’wana wa sling—loko angle exikarhi ka sling na horizontal yiri yitsongo, tension yiva yikulu. Kuya hi EN 1492-1 na ASME B30.9, vuswikoti byifanele kuhungutiwa loko ti slings titirhisiwa eka angle kumbe eka swivumbeko swa milenge yotala. Nkongomiso lowu wu hlamusela physics endzhaku ka ti angle factors, wu nyika matafula ya vuswikoti bya ti flat slings, naswona wu nyika nkongomiso lowu tirhaka wo hlayela ndzhwalo wo tirha lowu hlayisekeke eka matirhelo ya rigging ya misava ya xiviri.
