LA GUIDA DEFINITIVA ALLA CORDA HMPE

In questo articolo, vi offriamo una guida professionale ma di facile comprensione alla corda HMPE. Scoprirete la sua definizione, le sue proprietà principali e le sue applicazioni, oltre a consigli su come scegliere e personalizzare la corda più adatta alle vostre esigenze, migliorando la vostra comprensione e aiutandovi a scegliere l'opzione migliore.

COS'È LA CORDA HMPE?

Corda HMPELa fune in polietilene ad alto modulo è una fune ad alte prestazioni realizzata in fibre di polietilene ad altissimo peso molecolare (UHMWPE), caratterizzata da elevata resistenza, leggerezza, resistenza all'abrasione, ecc. È ideale per l'uso in ambienti esterni difficili.

Le applicazioni possibili includono fuoristrada, ormeggio in mare, rimorchio portuale, telecomunicazioni e sollevamento di grandi oggetti di precisione, ecc. Il suo peso ridotto, la non conduttività e la resistenza superiore lo rendono un'alternativa ai cavi in acciaio.

LE PRINCIPALI PROPRIETÀ DELLA CORDA HMPE

PESO SPECIFICO: 0,97G/CM3 GALLEGGIANTE

Essendo più leggero dell'acqua, può galleggiare, facilitando l'osservazione e il recupero durante le attività in acqua ed evitando di rimanere impigliato sott'acqua.

PUNTO DI FUSIONE: 146℃

Ad alte temperature offre una migliore stabilità termica, il che significa che la corda mantiene le sue prestazioni e non si deforma anche se sottoposta a calore significativo, aumentando la sicurezza durante l'uso.

ALLUNGAMENTO A ROTTURA: CIRCA 2%~3%

Il basso grado di allungamento non solo garantisce precisione durante le operazioni, con un allungamento minimo, ma consente anche di resistere a urti e trazioni improvvise. Questo è particolarmente importante per le operazioni di traino, ormeggio e sollevamento precise.

ASSORBIMENTO D'ACQUA: NESSUNO

Non assorbendo acqua, la corda non si inumidisce né si gonfia, preservandone la resistenza. Nelle attività in mare e all'aperto, la sua durata non è compromessa dall'assorbimento d'acqua e mantiene la sua leggerezza, rendendola facile da maneggiare anche quando è bagnata.

RESISTENZA UV: BUONA

La corda non si degraderà a causa della prolungata esposizione al sole, preservandone la resistenza e le prestazioni. Questo può prolungare la durata della corda e ridurre la frequenza di sostituzione.

RESISTENZA ALL'ABRASIONE: BUONA

Nelle operazioni fuoristrada, di sollevamento e di ormeggio, una buona resistenza all'abrasione consente alla cima di sopportare meglio l'attrito frequente e il contatto con oggetti ruvidi, preservandone così la resistenza e le prestazioni.

RESISTENZA CHIMICA: OTTIMA

L'eccellente resistenza chimica consente alla fune di mantenere la sua struttura completa e prestazioni stabili in ambienti con sostanze chimiche, aumentandone l'affidabilità in ambienti corrosivi e riducendo la frequenza delle sostituzioni.

I VANTAGGI INEGUAGLIABILI DELLA CORDA HMPE

RAPPORTO RESISTENZA/PESO PIÙ ELEVATO

A parità di diametro, la fune HMPE offre una resistenza maggiore rispetto alle funi in acciaio e ad altre funi in fibra come nylon, poliestere e polipropilene. Offre un diametro inferiore a parità di resistenza ed è più leggera, garantendo un'elevata resistenza e riducendo il peso complessivo.

LEGGEREZZA E MORBIDEZZA

Rispetto ai cavi in acciaio e ai cavi in fibra tradizionali come nylon e poliestere, i cavi in fibra HMPE sono più leggeri e flessibili, il che ne facilita la movimentazione, l'utilizzo e l'installazione durante i lavori all'aperto. Questo migliora significativamente l'efficienza del lavoro, riduce i tempi di manodopera e i costi.

ALTA SICUREZZA

Grazie alla sua galleggiabilità e leggerezza, la fune in HMPE non presenta rischi di impigliamento o affondamento durante le operazioni marittime. Durante il traino, il suo rinculo inferiore in caso di rottura riduce il rischio di lesioni rispetto all'elevato rinculo della fune in acciaio. Inoltre, la sua morbidezza e la sua leggera elasticità prevengono lesioni come i tagli che possono verificarsi durante la movimentazione della fune in acciaio, aumentando così la sicurezza.

FACILE DA LAVORARE

Grazie alla sua leggerezza, la corda HMPE è molto facile da trasportare e maneggiare. La sua consistenza morbida previene inoltre inutili infortuni al personale, migliorando l'efficienza e facendo risparmiare tempo.

LUNGA DURATA DI SERVIZIO

Rispetto alle tradizionali corde in fibra, la corda in fibra HMPE ha una durata maggiore grazie alla sua superiore resistenza all'abrasione, alla resistenza alla corrosione, alla protezione UV e alla resistenza alla fatica. Queste qualità le consentono di resistere meglio agli ambienti difficili e all'usura esterna, garantendone una maggiore durata. In alcuni casi, può anche essere riparata e riutilizzata.

BASSO COSTO

Sebbene il costo iniziale della fune sintetica HMPE sia superiore a quello delle funi in filo d'acciaio e delle funi in fibra tradizionale, la sua maggiore durata e la maggiore sicurezza riducono i costi operativi e di sicurezza a lungo termine. Ciò aumenta l'efficienza del lavoro e riduce i tempi di funzionamento, riducendo in definitiva il costo complessivo di utilizzo.

GLI SVANTAGGI DELLA CORDA HMPE

 NON RESISTENTE AL CALORE

A causa del suo punto di fusione relativamente basso, intorno ai 146 °C, la corda in fibra HMPE non è resistente al calore come la corda in aramide Kevlar, che ha un punto di fusione di circa 500 °C. Pertanto, potrebbe deformarsi o perdere prestazioni in caso di operazioni a temperature estremamente elevate.

ASSORBIMENTO DEGLI URTI LIMITATO

A causa del suo basso allungamento, pari a soli 2-3%, la fune HMPE non è in grado di assorbire e mitigare gli urti improvvisi o l'energia generata sotto carico con la stessa efficacia della fune in nylon. Pertanto, è necessaria la massima cautela in situazioni di utilizzo simili.

COME REALIZZARE LA MIGLIORE CORDA HMPE

Here you can find  how we craft high-quality HMPE rope at Duracordix, detailed step-by-step.

UTILIZZA LE MIGLIORI MATERIE PRIME

We start with using the best raw materials to ensure you the performance and quality of the rope. At Duracordix, we use the finest UHMWPE raw materials available in China to guarantee you our product quality, and we conduct single fiber strength tests on every batch of raw materials.

TORSIONE

Only UHMWPE fibers that pass quality control are used in the twisting process. Twisting tightly winds these strands together to form a strong rope. This process also alters the rope’s structure and strength, flexibility, and reliability, preparing it for the next stage of production. we use a Programmable Logic Controller (PLC) to control the twisting of the rope based on its size, which enhances the rope’s strength by 2-3%.

INTRECCIATURA

The twisted fibers are then braided. During the braiding process, multiple strands of yarn are interlaced in a specific way. This braiding method differs from simple twisting; it actually allows the yarns to form interlocking layers with each other, which increases the rope’s flexibility and stretchability.

FINITURA

After HMPE fiber rope is braided, we apply a glue coating. Because we soak it for an hour longer than our competitors, combined with our specially formulated glue, not only is the glue’s penetration enhanced, but the rope’s abrasion resistance and fatigue resistance are also improved. Additionally, this process gives the rope a higher brightness and greater strength.

ASCIUGATURA

After the HMPE rope is coated with glue, the drying process is very important. Once your rope is fully dried and cured, it enhances the adhesion between the fibers, thereby increasing the rope’s strength and durability, and extending its usage cycle and lifespan. This process also ensures that your rope’s brightness lasts longer.

TEST E CONTROLLO QUALITÀ

We conduct tensile strength tests, abrasion resistance tests, and corrosion resistance tests on each batch of your rope to ensure consistent performance and quality. Only those that meet our standards undergo a final visual inspection before being packaged and sent to customers.

COME SCEGLIERE LA TAGLIA GIUSTA

Choosing the right size of UHMPWE rope for your needs not only depends on the intended use and required tensile strength but also on safety and compatibility with the equipment. Additionally, it’s important to ensure it meets international standards and to seek expert advice for specific applications to make your informed decision.

RESISTENZA E DIAMETRO

To determine the actual weight of your objects for towing and lifting, consider a safety factor to decide the required strength of your rope and choose the appropriate diameter.

FATTORE DI SICUREZZA

For safety, when selecting your rope sizes, a safety factor is typically added. For example, tow ropes generally have a 1:2 safety factor, and lifting ropes (vertical lifting) typically have a 1:5 safety factor. This means your rope’s breaking strength should be 2 and 5 times the weight of the object, respectively.

TIPO DI UTILIZZO

When considering your rope applications, it’s important to specify the industry to meet the required diameter and strength standards. For instance, winches must not exceed a certain diameter to avoid impacting the length of rope needed. Additionally, the strength requirements for your lifting ropes differ from those used for the horizontal pulling.

COMPATIBILITÀ CON LE APPARECCHIATURE

When choosing your ropes, it’s essential to consider compatibility with the equipment. If your rope’s tensile strength is insufficient, it cannot guarantee normal operation and safety. To enhance abrasion resistance, adding a protective cover is necessary, which also increases your rope’s diameter.

STANDARD INTERNAZIONALI

We need to ensure that your HMPE rope meets the standards of the relevant country and provide the necessary certifications to prove that your product complies with international standards and requirements, meeting yours procurement criteria.

CONSULENZA ESPERTA

Considering safety, compliance, know-how, and customization, it’s best for you to consult with industry experts to ensure you choose HMPE ropes with the appropriate diameter, strength, and standard-compliant coatings.

 Protezione e manutenzione delle corde HMPE

 PROTEZIONE DELLA CORDA

EVITARE IL CONTATTO DIRETTO CON BORDI TAGLIENTI

When using your rope, avoid direct contact with sharp edges to prevent cuts that could render the rope unusable.

PULIRE LA CORDA DOPO L'USO

Always clean your rope after use to remove impurities like sand that can embed within the fibers, damaging the rope and reducing its tensile strength.

CONSERVAZIONE E AVVOLGIMENTO CORRETTI

After use, store your rope neatly coiled in a rope bag to prevent it from twisting or knotting, which can weaken its strength.

MANUTENZIONE DELLA CORDA

ISPEZIONI REGOLARI

Conduct regular inspections of your rope to assess wear, abrasion, and damage. If localized wear is observed, consider cutting out the worn section for repair to extend the overall lifespan.

RIPARAZIONI IMMEDIATE

If minor repairable damage is found in your rope, perform a safety assessment and review standards before making necessary repairs of your rope.

MAGAZZINAGGIO

Although your HMPE rope has good UV resistance and corrosion resistance, to extend its lifespan, store it in a cool, dry place away from moisture and heat sources.
