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

Xitirhisiwa xa tikhemikhali xi lava xirhendzevutani lexi nga ni xiphepherhele leswaku xi tlakusa swiphemu swa nsimbi leyi nga riki na swilo swo bola eka ndhawu leyi ku nga ni musi wa acid. Ndhawu yo lunghisa elwandle yi lava xibalesa lexi kotaka ku khoma mafurha ya hayidiroliki ni ku hlangana ni mati ya lwandle. Matirhelo lawa hamambirhi ya lava swirhendzevutana swa xiphepherhele leswi endliweke—kambe ku hlawula loku faneleke ka swilo swa hambana eka xin’wana ni xin’wana.

Lishenflex yi vile yi endla swilo swo endliwa swirhendzevutana leswi nga ni swiphepherhele ku tlula makume mambirhi ya malembe, naswona xivutiso xin’we lexi hi xi twaka nkarhi na nkarhi hi lexi: Polyester kumbe nayiloni—hi xihi xihlawuhlawu xo antswa? Nhlamulo ya kona a hi kanyingi yi olovaka. Hikuya hi Wikipedia’s entry on polyester , polyester i ntlawa wa ti polymers leti tekeriwaka enhlokweni hikokwalaho ka ku tiya ka yona, ku lwisana na ti khemikhali, na ku amukela ndzhongho wale hansi. Wikipedia ’s entry on nylon yi hlamusela leswaku nylon yi tekeriwa enhlokweni hikwalaho ka matimba ya yona, ku olova, na ku lwisana na ku rhurhumela. Swilo leswi haswimbirhi swi endla swirhendzevutana leswinene ngopfu swo tlakusa, kambe a swi cinciwi . Hi ku ya hi Canadian Center for Occupational Health and Safety (CCOHS) , swirhendzevutana swa nayiloni swi onhiwa hi ti- acid kambe swi lwisana ni ti- alkali, kasi swirhendzevutana swa polyester swi onhiwa hi ti- alkali kambe swi lwisana ni ti- acid . Xilotlelo i ku fambisana ni rungula leri ni mbango.

Ku Lwisana Ka Tikhemikhali: Ku Hambana Ka Vuhlayiseki Bya Nkoka

Ku hambana ka nkoka swinene exikarhi ka swirhendzevutana swa polyester na nylon flat i ku fambisana ka swona hi tikhemikhali . Ku hlawula nchumu lowu hoxeke wa ndhawu ya tikhemikhali swi nga endla leswaku ku tsandzeka lokukulu—hakanyingi ku nga ri na xilemukiso lexi vonakaka.

Kuya hi Liftex’s material comparison guide , ku hambana ka nkoka ka ku lwisana na ti khemikhali i :

Xihlovo: Liftex; CCOHS; CERTEX Xihlamusela-marito xa Denmark

CCOHS yi tiyisisa leswaku nylon yi onhaka eka ti acid leti sukelaka eka yin’we ku ya eka ku onhaka loku heleleke, kasi polyester yi lwisana na ti acid to tala kambe yi onhiwa hi ti alkali . CERTEX Denmark yi engetela leswaku switolwa swa ti- acid kumbe ti- alkali leti nga riki na khombo eka mpimo wa le hansi swi nga ha hlangana hi ku tirhisa ku khuluka naswona swi onha .

Xilemukiso xa vuhlayiseki xa nkoka : Ku onhaka ka tikhemikhali eka swirhendzevutani leswi endliweke hakanyingi a swi vonaki . Ti fibre ta tsana endzeni kasi sling yi vonaka yi tolovelekile ehenhla. Hi ku ya hi Empire Rigging , ku onhaka ka tikhemikhali hakanyingi a ku vonaki—tifibre ta tsana endzeni kasi xibalesa xi languteka xi tolovelekile hi ku helela ehandle, hi yona mhaka leyi ku tiva ndhawu leyi u nga eka yona swi nga swa nkoka u nga si hlawula nchumu lowu u wu tirhisaka .

Tindhawu ta Asidi—Hlawula Polyester

Loko u tlakusa etindhawini leti nga ni asidi—tifemeni ta tikhemikhali, ku endla tibetiri, ku hetisa nsimbi, swigayo swa maphepha— polyester i xihlawuhlawu lexinene. Ku hambana ni sweswo, nayiloni yi onhiwa hi ti- acid. Mazzella Companies yi xiya leswaku nayiloni yi onhaka eka ti- acid leti sukelaka eka ku onhaka lokutsongo ku ya eka ku onhaka loku heleleke, kasi polyester yi lwisana ni ti- acid to tala . Nkongomiso wa Vuhumelerisi bya Swikepe wa NSRP wu tsundzuxa leswaku tiasidi ta hydrochloric na sulphuric, hambi ku ri hi xivumbeko lexi pfanganisiweke, ti nga vanga ku lahlekeriwa lokukulu ka matimba eka nayiloni .

Tindhawu ta Alkali—Hlawula Nylon

Loko u tlakusa eka tindzhawu letingana alkali—ti caustic cleaning solutions, ku endliwa ka khonkhriti, ku lulamisiwa kokarhi ka tikhemikhali— nylon i xihlawuhlawu xo antswa. Polyester yi onhiwa hi ti- alkali, kasi nayiloni kahle-kahle a yi sirhelelekanga eka vuyelo bya ti- alkali . Nkongomiso wa swivumbeko swa tifibre ta UNIROPE wu xiya leswaku nayiloni yi ni ku tiya lokunene ni ti- aldehyde, ti- hydrocarbon, ti- ether ni ti- alkali tin’wana .

Tiprofayile ta ku Engetela: Ku ololoka ehansi ka Ndzhwalo

Ku hambana lokukulu ka vumbirhi exikarhi ka swirhendzevutana swa polyester na nylon leswi nga ni swiphepherhele i ku leha —leswaku xirhendzevutani xi ololoka ku fikela kwihi loko xi layichiwile.

Liftex yi nyika datha ya ku leha leyi landzelaka :

Xihlovo: Liftex; UNIROPE

Polyester—Ku Languta Ni Ku Tiyiseka

Ku leha ka le hansi ka polyester (3–4% eka ndzhwalo lowu ringanyetiweke) swiendla leswaku yiva nhlawulo lowu tsakeriwaka eka :

• Ku vekiwa ka ndzhwalo hi ku kongoma —ku ololoka lokutsongo swi vula ku lawula ku antswa

• Switirhisiwa swa ndhawu ya le hansi ya nhloko —ndhawu yitsongo yo yima leyi dyiwaka hi nkarhi wa ku tlakusa

• Mindzhwalo leyi nga kotiki ku tiyisela ku tlula-tlula kumbe ku rhendzeleka

• Matirhelo lawa ya lavaka ku tlakuka loku tiyeke, loku nga languteriwaka

Empire Rigging yi nyika xikombiso lexi tirhaka: ku tlakusa ndzhwalo wa timitara ta 20 hi xirhendzevutani xa nayiloni lexi andlalaka 10% swi endla leswaku ku leha kwalomu ka timitara timbirhi, kasi xirhendzevutani xa polyester a xi ta anama ntsena kwalomu ka nkombo wa tisentimitara . Eka tindhawu leti pfalekeke ta le henhla, ku hambana koloko i ka nkoka.

Nylon—Ku amukela ku chava na 'Ku rivalela'.

Ku leha ka le henhla ka nylon (6–10% eka ndzhwalo lowu ringanyetiweke) swinyika :

• Shock absorption —nchumu lowu 'nyika' wu nga si teka matimba hinkwawo

• Dynamic loading tolerance —swi antswa eka ndzhwalo lowu cinca-cincaka hi nkarhi wa ku tlakusa

• Ku rivalela eka hardware leyi nga tshamisekangiki —nylon yi rivalela ngopfu loko yi endliwa bunching na ku vekiwa ehenhla ka swivumbeko swa hardware leswi nga tshamisekangiki

• Enhanced operator safety margin —stretch yi tswonga ndzhwalo wa xitshuketa

Hi ku ya hi Liftex , ku ololoka lokukulu ka nayiloni ku tirha tanihi xisirhelelo xa ku rhurhumela, leswi endlaka leswaku yi va xihlawuhlawu lexi tsakeriwaka loko ndzhwalo wu nga ha cinca kumbe loko ku layicha loku cinca-cincaka ku ri xiphiqo .

Ku kufumela na Nhlamulo ya UV

Vuyelo bya ku kufumela

Nylon yi na hygroscopic —yi tswonga ndzhongho lowu humaka eka mbango. Kuya hi NSRP Ship Production Rigging Guide , nylon yi lahlekeriwa hi 15% wa matimba ya yona loko yi tsakamile . Liftex na CCOHS va tiyisisa leswi, va xiya leswaku ti nylon slings tinga lahlekeriwa hi 10–15% wa vuswikoti loko ti tsakama . Matimba ya vuyiseriwa loko yi omisiwa, kambe sling ayi fanelanga kutirhisiwa eka rated capacity loko yitsakama.

Polyester a yi tswongi mati naswona a yi lahlekeliwi hi matimba loko yi tsakamile . Leswi swi endla leswaku polyester yi va nhlawulo lowu tsakeriwaka eka :

• Switirhisiwa swa le lwandle na swa le lwandle

• Tilift ta le handle eka swiyimo swo tsakama

• Tindhawu letingana ndzhongho wale henhla

CERTEX Denmark yi xiya leswaku Dyneema® a yi tswongi mati, ku hambana ni swilo swin’wana swo tanihi polyester na polyamide .

Ku Lwisana na UV

Polyester yi nyika ku tiya ka le henhla ka UV loko yi pimanisiwa na nylon . Tifibre ta nayiloni ti khumbeka hi miseve ya UV ni ku vonakala ka dyambu, leswi endlaka leswaku ku lahlekeriwa swinene hi matimba hi ku famba ka nkarhi . Tikhampani ta Mazzella ti tsundzuxa leswaku tindhawu leti eka tona swirhendzevutana swa web leswi endliweke swi tshamaka swi ri eku vonakaleni ka ultra-violet swi nga khumba matimba ya webbing yo endliwa hi tidigri to hambana-hambana, ku sukela eka ku onhaka lokutsongo ku ya eka loku heleleke, naswona ku onhaka ka swilo ku hlengeletiwa . Eka swirhendzevutana leswi tirhisiwaka ehandle kumbe eka ku vonakala ka dyambu hi ku kongoma, polyester hi yona leyi tiyeke swinene.

Swipimelo swa Mahiselo

Ehansi ka EN 1492-1 , havumbirhi bya polyester na nylon flat slings swi lulamerile ku tirhisiwa na ku hlayisiwa eka mahiselo ya -40°C kuya eka 100°C . Leswi swi tirha eka switirhisiwa leswi haswimbirhi. Hambiswiritano, Empire Rigging yi xiya ku hambana loku tirhaka eka swipimelo swa ku tirhisiwa loku yaka emahlweni: nayiloni yi ringanisiwa ku fika eka 194°F (90°C), kasi polyester yi ringanisiwa ku fika eka 180°F (82°C)—yi le hansinyana . Ehenhla ka mahiselo lawa, switirhisiwa swisungula ku lahlekeriwa hi matimba.

Xitsundzuxo xa nkoka : Eka ndzhawu ya tikhemikhali, mahiselo lawa yanga hambana, naswona switsundzuxo swa muphakeri swifanele ku laviwa .

Ku tivisiwa: Ndlela Yo Hlawula Polyester Ku suka eka Nylon

ASME B30.9 na WSDA-WS-1 swi lava leswaku xirhendzevutani xin’wana na xin’wana xa webu xi va na thegi leyi khomanisiweke hi laha ku nga heriki leyi vulaka switirhisiwa . Ku engetela kwalaho, swirhendzevutana swa polyester swi ni layini ya wasi yo tivisa leyi lukiweke eka webbing —loko u vona layini ya wasi, i polyester . Ti slings ta nylon ati na layini leyi yo tiveka. Endlelo ra ku khoda mihlovo ehansi ka EN 1492-1 ri tirha eka switirhisiwa leswimbirhi hi ku ringana.

Nkongomiso wa ku Hlawula

Nkatsakanyo na Switsundzuxo leswi Tirhaka

Swirhendzevutana swa polyester ni swa nylon leswi nga ni swiphepherhele havumbirhi bya swona swi nyikela matimba lamanene ni ku tiya, kambe a swi cinci . Ku hlawula nchumu lowu hoxeke wa ndhawu ya wena swi nga endla leswaku ku onhaka loku fihliweke ni ku tsandzeka ka xitshuketa.

Swilo swa nkoka leswi tekiwaka:

1. Tindhawu ta acid = Polyester —nylon yi onhiwa hi ti acid

2. Tindhawu ta alkali = Nylon —polyester yi onhiwa hi ti alkali

3. Precision lifts = Polyester —ku leha ka le hansi swi nyika vulawuri

4. Dynamic loads = Nylon —ku ololoka loku tlakukeke ku tswonga switshuketa

5. Handle/ku tsakama = Polyester —yi nga ngheniwi hi UV naswona yi nga ngheniwi hi ndzhongho

6. Languta layini ya wasi —swirhendzevutana swa polyester swi ni layini ya tracer ya wasi; nayiloni a yi endli tano

7. Minkarhi hinkwayo tiyisisa thegi —ASME B30.9 yi lava ku tivisiwa ka swilo eka thegi ya sling

Lishenflex yi endla swin’wetsin’wetsi swa polyester na nylon flat slings kuya hi EN 1492-1 na ASME B30.9 standards, na ku tiveka ka swilo leswi nga erivaleni na swikoweto swa vuswikoti leswi khodiweke hi mihlovo. Hi nyika nkongomiso eka ku hlawula switirhisiwa leswi simekiweke eka ndhawu ya wena yo karhi ya tikhemikhali na swilaveko swa ku tirhisiwa.

Loko u lava mpfuneto wo kumisisa loko polyester kumbe nylon yi ri nhlawulo lowunene eka ntirho wa wena wo tlakusa—kumbe u lava mpfuneto wo kuma xirhendzevutani lexi faneleke xa ndhawu leyi nga na tikhemikhali—hi kombela u rhumela imeyili eka sales@lishenflex.com , naswona ntlawa wa hina wa xithekiniki wu ta nyika nseketelo wa munhu hi xiyexe.
