Polyester vs. Nylon Flat Slings: Chemical Resistance uye Elongation Profiles

Chirimwa chemakemikari chinoda chifuramabwe chekusimudza simbi isina tsvina munzvimbo ine utsi hweasidhi. Nzvimbo yekugadzirisa marine inoda chipfuramabwe chinogona kubata hydraulic oiri uye kuratidzwa kwemvura yegungwa. Masevhisi ese ari maviri anoda synthetic flat slings-asi iyo chaiyo yemhando sarudzo yakasiyana kune yega yega.

Lishenflex yanga ichigadzira synthetic zvipfuramabwe zveanopfuura makumi maviri emakore, uye mubvunzo mumwe watinogara tichinzwa ndewekuti: Polyester kana naironi - ndeipi sarudzo iri nani? Mhinduro yacho haisi nyore. Zvinoenderana neWikipedia yekupinda papolyester , polyester iboka remapolymer anokosheswa kusimba kwayo, kuramba kwemakemikari, uye kuderera kwehunyoro. Kupinda kweWikipedia panaironi kunotsanangura kuti naironi inokosheswa nekuda kwesimba rayo, kusimba, uye kuramba kweabrasion. Zvishandiso zvese zviri zviviri zvinogadzira zvipfuramabwe zvakanakisa zvekusimudza, asi hazvichinjike . Maererano neCanadian Center for Occupational Health and Safety (CCOHS) , zvipfuramabwe zvenaironi zvinokuvadzwa neasidhi asi zvinoramba alkali, nepo polyester slings inokuvadzwa nealkali asi inoramba maasidhi. Chinokosha ndechekufananidza zvinhu nemhoteredzo.

Chemical Resistance: The Critical Safety Difference

Musiyano wakanyanya kukosha pakati pepolyester nenylon flat slings ndeyekuenderana kwavo kwemakemikari . Kusarudza zvinhu zvisiri izvo zvemhoteredzo yemakemikari kunogona kutungamirira kukundikano ine ngwavaira—kazhinji pasina nyevero inooneka.

Zvinoenderana neLiftex's material yekuenzanisa gwara , iwo akakosha makemikari kuramba misiyano ndeiyi :

Kunobva: Liftex; CCOHS; CERTEX Denmark

CCOHS inosimbisa kuti naironi inokonzerwa nekuora muasidhi kubva kune imwe kusvika pakuora zvachose, nepo polyester inopikisa kune akawanda asidhi asi yakakuvadzwa nealkalis. CERTEX Denmark inowedzera kuti zvigadziriso zveasidhi kana alkalis zvisingakuvadze pakudzika kwakadzika zvinogona kunyura kuburikidza nekubuda uye kukonzera kukuvara.

Yambiro yakakosha yekuchengetedza : Kukuvadzwa kwemakemikari kune ekugadzira slings kazhinji haaonekwe . Mafiibhi acho anopera simba mukati ukuwo chipfuramabwe chichiita sechakanaka pamusoro. Maererano neEmpire Rigging , kukanganisa kwemakemikari kunowanzova kusingaoneki-mafibers anopera simba mukati apo chipfuramabwe chinotaridzika zvakakwana kunze, ndicho chikonzero kuziva zvakatipoteredza zvakakosha usati wasarudza zvinhu zvako.

Asidhi Nzvimbo-Sarudza Polyester

Kana uchisimudza munzvimbo dzine acid exposure - makemikari zvidyarwa, kugadzirwa kwebhatiri, kupedzisa simbi, mapepa emagetsi - polyester ndiyo sarudzo chaiyo. Nylon, zvakasiyana, inoparadzwa nemaasidhi. Mazzella Companies anocherekedza kuti naironi iri pasi pekuora mumaasidhi kubva padiki kusvika pakuora zvachose, nepo polyester inoshingirira kune akawanda acid. Iyo NSRP Ship Production Rigging Guide inoyambira kuti hydrochloric uye sulfuric acids, kunyangwe mune yakaderedzwa fomu, inogona kukonzera kurasikirwa kukuru kwesimba munylon.

Alkali Nzvimbo-Sarudza Nylon

Kana uchisimudza munzvimbo dzine alkali exposure - caustic yekuchenesa mhinduro, kugadzira kongiri, kumwe kugadzirisa kemikari - nylon ndiyo sarudzo iri nani. Polyester inokuvadzwa nealkalis, nepo nylon isingaite kudzivirirwa kune mhedzisiro yealkalis. Iyo UNIROPE faibha zvivakwa gwaidhi inoratidza kuti naironi ine kurwisa kwakanaka kune aldehydes, mahydrocarbon, ether, uye mamwe alkalis.

Elongation Profiles: Tambanudza Under Load

Musiyano mukuru wechipiri pakati pepolyester nenylon flat slings ndeyekurebesa - kuti chipfuramabwe chinotambanudzwa zvakadii kana chatakurwa.

Liftex inopa iyo inotevera elongation data:

Kunobva: Liftex; UNIROPE

Polyester-Kururamisa uye Kugadzikana

Polyester's low elongation (3-4% payakayerwa mutoro) inoita iyo sarudzo yakasarudzika ye:

• Precise load positioning — kutambanudza kuduku kunoreva kudzora kuri nani

• Yakadzika-yemusoro maapplication - yakaderera yakatwasuka nzvimbo inopedzwa panguva yekusimudza

• Mitoro isingagoni kushivirira kubhowekana kana kuzungunuka

• Mashandiro anoda kusimudzwa kwakadzikama, kunofanotaurwa

Empire Rigging inopa muenzaniso unoshanda: kusimudza 20-foot load nechipfuramabwe chenaironi chinotambanuka 10% chinoguma nekurebesa mafiti maviri, ukuwo chipfuramabwe chepolyester chaigona kutambanudza masendimita manomwe chete. Munzvimbo dzakasimba dzepamusoro, musiyano iwoyo unokosha.

Nylon - Shock Absorption uye 'Kukanganwira'

Nylon yakakwira elongation (6-10% payakayerwa mutoro) inopa:

• Kunyura kwekatyamadzo -zvinhu 'zvinopa' zvisati zvatora simba rakazara

• Dynamic loading tolerance - zvirinani kune mitoro inoshanduka panguva yekusimudza

• Kukanganwira pane zvisina kujairika Hardware - nylon inonyanya kuregerera kana ikaiswa pasi pekusungwa uye kuiswa pamusoro pezvisina kujairika zvimiro zvehardware.

• Kuwedzeredzwa kwekuchengetedza muganho wevashandisi - kutambanudza kunotora mitoro yakangoerekana yavapo

Sekureva kwaLiftex , yakakwira naironi yakatambanudzwa inoita sechinhu chinokatyamadza, zvichiita kuti ive sarudzo inosarudzika kana mitoro inogona kutama kana kurodha zvine simba.

Unyoro uye UV Mhinduro

Unyoro Migumisiro

Nylon ine hygroscopic - inotora unyoro kubva kune zvakatipoteredza. Maererano neNSRP Ship Production Rigging Guide , naironi inorasikirwa ne15% yesimba rayo pakanyorova . Liftex neCCOHS . zvichisimbisa izvi, zvichiona kuti zvipfuramabwe zvenaironi zvinogona kurasikirwa negumi neshanu muzana kana zvanyorova Simba rinodzoserwa pakuomeswa, asi chipfuramabwe hachifanirwe kushandiswa pachiyero chakayerwa kana chanyorova.

Polyester haitore mvura uye haina kurasikirwa nesimba kana yanyorova. Izvi zvinoita kuti polyester ive sarudzo yakasarudzika ye:

• Marine uye offshore application

• Kusimudza kwekunze mumamiriro ekunyorova

• Nzvimbo dzine hunyoro hwepamusoro

CERTEX Denmark inocherekedza kuti Dyneema® haitore mvura, kusiyana nezvimwe zvinhu zvakaita sepolyester uye polyamide.

UV Kupokana

Polyester inopa yakakwirira UV kupikisa kana ichienzaniswa nenylon. Nylon faibha dzinokanganiswa nemwaranzi yeUV uye chiedza chezuva, zvichikonzera kurasikirwa kukuru kwesimba nekufamba kwenguva. Mazzella Companies inoyambira kuti nharaunda umo madhizaini edandemutande anogara achivhenekerwa kune ultra-violet mwenje anogona kukanganisa simba rekugadzira webbing mumadhigirii akasiyana, kubva padiki kusvika pakudzikira, uye kuti kuderera kunowedzera . Kune machira anoshandiswa kunze kana muzuva rakananga, polyester ndiyo yakasarudzika sarudzo.

Tembiricha Miganhu

Pasi pe EN 1492-1 , polyester uye naironi flat slings akakodzera kushandiswa uye kuchengetwa mutembiricha renji -40°C kusvika 100°C . Izvi zvinoshanda kune zvese zvishandiso. Zvisinei, Empire Rigging inocherekedza musiyano unoshanda mumiganho yekushandisa inoenderera: naironi yakatarwa kusvika ku194 ° F (90 ° C), nepo polyester yakayerwa kusvika 180 ° F (82 ° C) - yakaderera zvishoma. Pamusoro pekushisa uku, zvinhu zvinotanga kupera simba.

Chirevo chakakosha : Munzvimbo yemakemikari, idzi tembiricha dzinogona kusiyana, uye zano remutengesi rinofanira kutsvagwa.

Kuzivikanwa: Maitiro ekuudza Polyester kubva Nylon

ASME B30.9 uye WSDA-WS-1 inoda kuti dandemutande rega rega rive netag yakanamirwa zvachose inotaura zvinhu. Pamusoro pezvo, zvipfuramabwe zvepolyester zvine tambo yeblue identification yakarukwa mukati mewebhu — kana ukaona tambo yebhuruu, ipolyester. Nylon slings haina iyi yekuzivikanwa mutsara. Iyo color-coding system pasi pe EN 1492-1 inoshanda kune ese ari maviri zvinhu zvakaenzana.

Sarudzo Guide

Pfupiso uye Mazano Anoshanda

Polyester nenylon flat slings zvese zvinopa simba rakanakisa uye kusimba, asi hazvichinjike . Kusarudza zvinhu zvisiri izvo kune yako nharaunda kunogona kutungamirira kune yakavanzwa kuderera uye kukundikana kamwe kamwe.

Zvokudya zvakakosha:

1. Acid environments = Polyester -nylon inoparadzwa nemaasidhi

2. Alkali nharaunda = Nylon - polyester yakakuvadzwa nealkalis

3. Precision inosimudza = Polyester -yakaderera kureba inopa kutonga

4. Mitoro ine simba = Naironi -kutambanudza kwepamusoro kunotora kuvhunduka

5. Kunze/kunyorova = Polyester —Isingaite UV uye inodzivirira mwando

6. Tarisa mutsetse webhuruu —polyester slings dzine blue tracer line; naironi haina

7. Gara uchisimbisa iyo tag -ASME B30.9 inoda chiziviso chechinhu pane chipfuramabwe

Lishenflex inogadzira zvese zviri zviviri polyester uye nayiloni flat slings kune EN 1492-1 uye ASME B30.9 zviyero, zvine yakajeka ruzivo rwezvinhu uye mavara-coded kugona mamark. Isu tinopa nhungamiro pakusarudza zvinhu zvichibva pane yako chaiyo makemikari nharaunda uye maapplication zvinodiwa.
