Mahiselo, UV Ni Tikhemikhali: Ndlela Leyi Swilo Swa Ntivo-mbango Swi Onhaka Swilo Swa Wena Swo Tlakusa Ha Yona

A lifting sling  yi hlayisiwa ehandle kuringana tinhweti tinharhu. Yi languteka yi ri kahle—ku hava ku tsemiwa, ku hava ku rhurhumela. Kambe loko yi vekiwa ehansi ka ndzhwalo, ya tshoveka. Vulavisisi byi paluxa xivangelo: Ku onhaka ka UV. Xirhendzevutani lexi xi lahlekeriwe hi 40% wa matimba ya xona ku nga si va na munhu loyi a xiyeke xiphiqo.

Xiendlakalo lexi a hi xa ku ehleketa. Hi ku ya hi Rigging Institute , swirhendzevutana leswi nga ni tijakete ta muvala wo vonikela swi nga lahlekeriwa hi ku fika eka 40 wa tiphesente ta matimba ya swona lamakulu eka nkarhi wa tin’hweti ta tsevu loko swi hambeta swi hlangana ni UV . Nkongomiso wa vuhlayiseki wa Liftex Slings  wu tiyisisa leswaku tindhawu leti eka tona swirhendzevutani swa webbing yo endliwa swi tshamaka swi ri eku vonakaleni ka ultraviolet swi nga khumba matimba ya swirhendzevutani swa webbing yo endliwa hi tidigri to hambana ku suka eka ku onhaka kutsongo ku ya eka ku onhaka loku heleleke .

 

Lishenflex  yi endle swirhendzevutana swo tlakusa swilo leswi endliweke ku tlula makume mambirhi ya malembe, naswona rungula ra hina ra ku kambela ri tiyisekisa leswaku ku onhiwa ka mbango i xin’wana xa swivangelo leswi tolovelekeke ngopfu—naswona leswi honisiwaka ngopfu—swa ku tsandzeka ka swirhendzevutana. Kuhambana na ku onhaka ka michini kufana na ku tsemiwa kumbe ku tshoveka, ku onhaka ka mbango switala kuva swinga vonaki kufikela loko kuri na nkarhi.

 

Mahiselo: Vuyelo bya kuhisa na ku titimela eka ti Synthetic Slings

Ti fibre ta synthetic tina swipimelo swa mahiselo leswi hlamuseriweke. Ku tlula swipimelo leswi—hambi ku ri swa xinkarhana—swi nga kavanyeta matimba ya xibalesa hilaha ku nga heriki.

 

Ku Onhaka ka Ku Hisa

 

Kuya hi swiletelo swa vuhlayiseki swa CCOHS na Liftex, swirhendzevutani swa synthetic swi onhiwa hi mahiselo yale henhla ka swipimelo leswi landzelaka:

 

Xihlovo: Nkongomiso wa Swilo swa Webu swa Xiendliwa xa CCOHS; Xiletelo xa Vuhlayiseki bya Liftex Sling

 

Liftex yi tsundzuxa leswaku swikombiso leswi vonakaka swa ku onhaka ka ku hisa swi nga katsa ku pfimba, ku n’oka, ku cinca ka muhlovo (ku charring), ni ku engeteleka ka ku tiya ka swilo leswi sling . Eka swiyimo swin’wana, xirhendzevutani xi nga ha tiya ni ku tshoveka handle ka ku hisiwa loku vonakaka—leswi endlaka leswaku swi tika ku vona ku onhaka hi ku hisa. Hilaha Mazzella Companies yi vulaka hakona, vumbhoni bya ku onhaka hi ku hisa i xiyimo lexi lavaka ku susiwa hi xihatla entirhweni .

 

OSHA yi tiyisisa leswi hi ku xaxameta ku n’oka, ku charring, kumbe ku fafazeriwa ka weld eka xiphemu xihi na xihi xa sling tani hi xiyimo xo susiwa hi xihatla eka ntirho ehansi ka WAC 296-155-55825 .

 

Xitsundzuxo xa nkoka: Ku onhaka hi ku hisa ku nga humelela hambiloko ku nga ri na ku khumbana loku kongomeke ka malangavi. Ku tshama nkarhi woleha eka tindzhawu leti hisaka, tiphayiphi ta steam kumbe weld splatter swinga tlakusa mahiselo ya fibre kutlula swipimelo leswi hlayisekeke.

 

Vuyelo bya Mahiselo ya Xirhami

 

Ti slings ta synthetic na tona ti tirha hindlela yohambana eka tindzhawu leti titimelaka. Hambi leswi polyester na nylon swinga brittle eka mahiselo yo titimela, ndzhongho endzeni ka ti fibres wunga titimela, leswi endlaka leswaku sling yi tiya naswona yinga ha koti ku olova. Kuya hi CCOHS, swirhendzevutani leswi tsakamaka leswi titimelaka swinga lahlekeriwa hi vuswikoti byo rhwala naswona swifanele ku omisiwa kahle loko swinga se tirhisiwa.

 

Switsundzuxo leswi tirhaka eka vulawuri bya mahiselo:

 

U nga tshuki u hlayisa swirhendzevutana ekusuhi ni swihlovo swo hisa— tiphayiphi ta mpfula, ti- radiator kumbe ku vonakala ka dyambu loku kongomeke

 

Tirhisa swisirhelelo swo hisa  loko u tlakusa ndzhwalo wo hisa (sleeves yo pfalela, mahlo ya pad) .

 

Papalata ku tirhisa swirhendzevutani eka ndzhwalo lowu tlulaka 90°C eka polyester na nylon, 80°C eka polypropylene

 

Kambela swirhendzevutana leswi nga eku hiseni  leswaku swi tsanile, swi charring kumbe swi cinca muhlovo

 

UV Radiation: Mudlayi wa Matimba yo Miyela

UV radiation leyi humaka eka ku vonakala ka dyambu i xin’wana xa swilo leswi onhaka swinene mbango eka swirhendzevutana swo tlakusa swilo leswi endliweke. Kuhambana na ku onhaka ka tikhemikhali kumbe hi kuhisa, ku onhaka ka UV swi hlengeletana naswona aswi hundzuki.

 

Hi ku ya hi Liftex Slings safety guide , swikombiso leswi voniwaka swa ku onhaka ka ultraviolet swi katsa:

 

Ku basa ku suka eka muvala wa sling  (ku nyamalala) .

 

Ku engeteleka ka ku tiya ka swilo swa sling

 

Surface abrasion eka tindzhawu leti hi ntolovelo tinga hlangana na ndzhwalo

 

Rigging Institute yi nyikela nkongomiso lowu kongomeke swinene: swirhendzevutana leswi nga ni tijakete ta muvala wo vonikela (wo basa, wo tshwuka, wa wasi ni wo tshwuka) swi nga lahlekeriwa hi ku fika eka 40 wa tiphesente ta matimba ya swona lama hetelelaka eka nkarhi wa tin’hweti ta tsevu loko swi hambeta swi hlangana ni UV. Mihlovo ya ntima—yo tshwuka, ya buraweni wo dzwihala, ya rihlaza ro dzwihala ni ya ntima—yi nyikela nsirhelelo lowunene eka ku onhaka ka UV.

 

Khodi ya Vulawuri ya Washington (WAC 296-155-55825)  hi ku kongoma yi xaxameta ku cinca ka muhlovo, tifibre leti tshovekeke, na tindhawu to tiya kumbe to tiya leti nga kombisaka ku onhaka ka tikhemikhali kumbe ultraviolet/ku vonakala ka dyambu tanihi xiyimo lexi lavaka ku susiwa hi xihatla entirhweni.

 

Lishenflex ’s field data yi tiyisisa leswaku ti slings leti hlayisiweke ehandle kumbe leti tirhisiwaka eka ku vonakala ka dyambu hiku kongoma handle ka nsirhelelo wa UV tinga lahlekeriwa hi 20-40% wa matimba ya tona lawa ya ringanyetiweke eka 6-12 wa tinhweti, kuya hi muhlovo xikan’we na matimba ya exposure.

 

Swiendlo swa nkoka swo sivela ku onhaka ka UV:

 

Hlayisa swirhendzevutani eka tindzhawu ta munyama, leti omeke  loko tinga tirhisiwi

 

Hlawula swirhendzevutani swa muhlovo wa ntima  (wotshuka, buraweni, rihlaza ro dzwihala) kuva switirhisiwa ehandle

 

Cinca-cinca inventory ku hunguta ku hlangana na UV loku yaka emahlweni

 

Languta swirhendzevutani leswi tirhisiwaka ehandle vhiki na vhiki  leswaku swi nyamalala na ku tiya

 

Ku Hlangana na Tikhemikhali: Vuhlayiseki byo Hlawuleka bya Swilo

A hi tifibre hinkwato leti endliweke hi ndlela leyi fanaka eka tikhemikhali. Ku tirhisa swilo leswi hoxeke endhawini leyi hoxeke swi nga endla leswaku u tsandzeka hi ku hatlisa, hi khombo lerikulu.

 

Hi ku ya hi CCOHS, swirhendzevutana swa nayiloni swi onhiwa hi ti- acid , kasi swirhendzevutana swa polyester swi onhiwa hi ti- alkali . Nkongomiso wa Liftex Slings wu engetela leswaku tikhemikhali tinga khumba matimba ya sling hi ti degree to hambana hambana, kusuka eka ku onhaka kutsongo kuya eka ku onhaka hinkwako, kuya hi khemikhali yokarhi, nhlayo ya yona, na nkarhi lowu yinga hlangana na yona.

 

Ku pimanisiwa ka ku tiya ka tikhemikhali

 

Xihlovo: Nkongomiso wa Swilo swa Webu swa Xiendliwa xa CCOHS; Xiletelo xa Vuhlayiseki bya Liftex Sling

 

CERTEX Denmark yi tlhela yi kandziyisa leswaku swirhendzevutana swa malapi yo endliwa swi hlaseriwa ngopfu hi tikhemikhali leti nga fambisaniki—leswi nga tsanisaka kumbe ku herisa tifibre handle ko onhaka loku vonakaka . Liftex yi tsundzuxa leswaku loko xirhendzevutani xi hlangana ni tikhemikhali ta asidi kumbe leti pfurhaka naswona fibre ya kona yi onhakile, xirhendzevutana xa tiya naswona xi tshoveka, leswi endlaka leswaku muhlovo wu va wa buraweni kumbe wa ntima . Swirhendzevutana leswi swifanele ku susiwa hiku hatlisa eka ntirho.

 

Xitsundzuxo xa nkoka: Ku onhaka ka tikhemikhali ku nga humelela hambi ku ri hi musi kumbe mpfula, ku nga ri ntsena ku khumbana ka mati hi ku kongoma. Ti slings leti hlayisiweke eka tindzhawu letingana musi wa ti khemikhali tinga onhaka handle ka ku hlangana na mati lawa ya vonakaka.

 

Switsundzuxo leswi tirhaka swa vulawuri bya ku hlangana na tikhemikhali:

 

Fanisa swilo swa sling na ndzhawu ya tikhemikhali (polyester eka ti acid, nylon eka ti alkali) .

 

Hlantswa swirhendzevutani hi ku hatlisa endzhaku ko hlangana na tikhemikhali (landzela swiletelo swa muendli) .

 

Languta swirhendzevutani leswi tirhisiwaka eka tindzhawu ta tikhemikhali nkarhi na nkarhi  loko swinga tiya, swi cinca muhlovo kumbe swinga tshoveka

 

Susa swirhendzevutani eka ntirho loko ku ehleketeleriwa leswaku ku onhaka hi tikhemikhali

 

Vuyelo Lebyi Hlanganisiweke: Loko Swilo Swo Tala Swi Hlangana

Swilo swa mbango a swi tali ku tirha hi ku tihambanisa. Xirhendzevutani lexi hlayisiweke ehandle xi nga ha hlangana na UV, mpfula (ndzhongho) na ku rhendzeleka ka mahiselo hi nkarhi wun’we. Vuyelo lebyi hlengeletiweke hakanyingi byi va byikulu ku tlula nhlayo ya swilo ha xin’we-xin’we.

 

Lishenflex ’s lab testing data yikombisa leswaku sling leyi hlanganaka na UV na musi wa tikhemikhali yinga lahlekeriwa hi kufika eka 60% wa matimba ya yona eka masiku ya 90—loko ku pimanyisiwa na 30-40% kusuka eka xivangelo xin’wana na xin’wana ntsena. Vuyelo lebyi bya ku hatlisa hi byona byi endlaka leswaku ku kamberiwa nkarhi na nkarhi swiva swa nkoka swinene eka swirhendzevutani leswi tirhisiwaka eka tindzhawu to tika.

 

Nkongomiso wa indasitiri ku suka eka ASME B30.9 wu lava leswaku swirhendzevutana leswi nga eka swiyimo swo tika swa vukorhokeri—leswi katsaka ku hlangana na ku hisa, tikhemikhali, na UV—swi fanele ku kamberiwa nkarhi na nkarhi ku tlula swirhendzevutani eka vukorhokeri bya ntolovelo .

 

Swipimelo swa ku Kambela na ku Huma ePenceni swa ku Onhaka ka Ntivo-mbango

Hi ku ya hi milawu ya ASME B30.9 na OSHA, swikombiso leswi landzelaka swa ku onhaka ka mbango swi lava ku susiwa hi xihatla eka vukorhokeri:

 

Xihlovo: ASME B30.9; WAC 296-155-55825

 

Hikuya hi nkongomiso wa Liftex, swirhendzevutani leswi tirhisiwaka eka tindzhawu letingana UV leyi yaka emahlweni swifanele ku kamberiwa hi vumbhoni lembe na lembe kumbe nkarhi na nkarhi kuya hi ku tika ka ku hlangana na swona . ASME B30.9 yi lava leswaku ku kamberiwa ka nkarhi na nkarhi ku endliwa hi munhu loyi a faneleke na leswaku tirhekhodo ta ku kamberiwa loku heleleke ka sweswinyana ti hlayisiwa.

 

Lishenflex  yi ringanyeta leswaku ti slings letinga hlangana na swiyimo swo tika swa mbango ti kamberiwa n’hweti na n’hweti kumbe kotara naswona ti susiwa eka ntirho eka xikombiso xosungula xa ku onhiwa ka mbango.

Nkatsakanyo na Switsundzuxo leswi Tirhaka

Ku hisa, miseve ya UV ni ku hlangana ni tikhemikhali i swilo swinharhu leswi tolovelekeke swinene swa mbango leswi onhaka swirhendzevutana swo tlakusa swilo leswi endliweke. Kuhambana na ku onhaka ka michini, ku onhiwa ka mbango hakanyingi aswi vonaki kufikela loko sling yi tsandzeka ehansi ka ndzhwalo.

 

Swilo swa nkoka leswi tekiwaka:

 

1. Swipimelo swa mahiselo a swi vulavurisaniwi—polyester na nylon swi onhaka ehenhla ka 90°C; polypropylene ehenhla ka 80°C

 

2. Ku onhaka ka UV ka hlengeletiwa naswona a ku hundzuki—muvala lowu nyamalaka i xikombiso xo sungula xa xilemukiso; swirhendzevutana swa muvala wa ntima swi nyikela nsirhelelo wo antswa

 

3. Ku onhaka ka tikhemikhali ku vangiwa hi swilo swo karhi—polyester yi lwisana ni ti- acid kambe yi onhiwa hi ti- alkali; nayiloni hi yona leyi hambaneke

 

4. Kambela nkarhi na nkarhi eka tindhawu to tika—vutirheli byo tika byi lava ku kamberiwa n’hweti na n’hweti ku ya eka kotara

 

5. Ku hlayisiwa kahle swi sivela ku onhaka—tindzhawu leti kufumelaka, leti omeke, leti nga ni munyama ti sirhelela swirhendzevutana leswaku swi nga onhi mbango

 

Lishenflex  yi endla swirhendzevutani swo tlakusa swa polyester leswi nga na swiengeteri leswi nga lwisaniki na UV na swikoweto swa vuswikoti leswi nga na khodi ya mihlovo leyi nga erivaleni, leswi fambisanaka na swipimelo swa EN 1492 na ASME B30.9. Switirhisiwa swa hina swi kumeka hi swihlawulekisi swa mihlovo ya ntima eka switirhisiwa swa le handle, naswona hi nyika ndzetelo wo kambela ku pfuna ntlawa wa wena ku vona ku onhaka ka mbango ka ha ri na nkarhi.

 

Loko u lava mpfuneto wo kambela makhombo ya mbango eka matirhelo ya wena yo tlakusa—kumbe u lava mpfuneto wo hlawula swirhendzevutani leswi nga na ku lwisana loku faneleke ka tikhemikhali na UV eka ndhawu ya wena yo karhi—hi kombela u rhumela imeyili eka sales@lishenflex.com , naswona ntlawa wa hina wa xithekiniki wu ta nyika nseketelo wa munhu hi xiyexe.
