How waterproof should a hiking backpack be for heavy rain?

For alpine-level storms, a 5000mm hydrostatic head rating with welded seams is recommended. PU-coated fabrics under 2000mm are insufficient for extended heavy rain.

Are waterproof hiking bags truly waterproof for submersion?

Most hiking bags are not made for submersion. Only dry bag-style backpacks with TPU lamination and roll-top closures can resist brief immersion.

Is TPU better than PU for waterproof backpacks?

TPU offers higher abrasion resistance, better waterproof retention, weldable seam construction, and greater compliance with PFAS-free standards. PU is less durable in wet climates.

Do waterproof zippers make a big difference?

Yes. Waterproof zippers such as YKK AquaGuard reduce water ingress significantly, especially under directional rain or river spray.

Why does my waterproof backpack still get wet inside?

Water often enters through seam holes, non-waterproof zippers, or worn fabric coatings. Waterproofing depends on all components working together.

Matumba a madzi oyenda: Zomwe zili

Oyenda mtunda wautali nthawi zambiri amaganiza kuti chikwama cha madzi oyendayenda ndi "chikwama chilichonse chomwe chimayambitsa mvula." Tsoka ilo, malingaliro olakwikawa amatsogolera kuvala zovala, magetsi owonongeka ndi zoopsa zosafunikira nthawi yayitali. Mphepo yamkuntho siyinthu imodzi - ndi makhalidwe, kuphatikiza sayansi yazachilengedwe, seam uningrier, miyezo yoyeserera ndi malamulo azachilengedwe omwe adasintha mwachangu zaka zisanu zapitazi.

Nkhaniyi ikufotokoza MALANGIZO, Zochita zenizeni zapadziko lonse lapansi, ndipo Zosintha Zosintha tsopano akulongosola m'badwo wotsatira wa matumba akuyenda pansi mapangidwe. Kaya mukufanizira tsiku lokhala ndi mapepala okhala ndi TPU thumba labwino kwambiri la madzi Kwa kudalirika kwa nthawi yayitali, muphunzira ndendende zomwe mungakhale nazo.

Thumba la madzi oyendayenda lojambulidwa pagombe, kuwonetsa mchenga komanso kugwira ntchito zakunja.

Shunwei 30l thumba loyenda panyanja lomwe limawonetsedwa pagombe la dzuwa kuti liziwonetsa kulimba kwakunja.

Chifukwa chiyani kuthirira m'matumba oyambira nthawi zambiri samamvetsetsa

Funsani aliyense watsopano, "Kodi chimapangitsa chikwama chamadzi chopanda?"
Ambiri adzayankha kuti: "Zinthu zokutira."

Izi ndi zokha 20% za chowonadi.

Zowonadi chikwama cha madzi oyendayenda amadalira:

• Nsalu ya nsalu + yophimba
• Hydrostatic mutu (mzere wamadzi)
• Njira Yomanga Yomanga
• Zipper subproof r
• Konzani geometry yomwe imalepheretsa Poolog
• Miyezo yoyeserera: Iso 811 / en 343 / yis l 1092
• Kutsatira kwa PFAS Pambuyo pa 2023

Ngati wina wa izi alephera, paketiyo ndi "yolimbana ndi madzi," osati madzi oyambitsa madzi.

Mwachitsanzo:
Ndondomeko ya nayiloni yokhala ndi zokutira 2000mm Pute idzabweza, koma mabowo osowa satha kutayikira msanga, kutanthauza kuti wosuta akukhulupirira kuti adagula a chikwama cha madzi oyendayenda Zikakhala kuti zenizeni - si madzi oyambitsa madzi.

Kumvetsetsa Vounts Orproof: Zomwe ISO 811 ndi EN 343 Zikutanthauza

Zida zamadzi: PU vs tpu vs pvc-zomwe okwera oyenera amadziwa

PU yophimba (poureurethane)

Njira yodziwika kwambiri komanso yachuma matumba oyenda m'madzi.
Ubwino: zopepuka, zosinthika.
Zofooka: Hydrolysis (kuwonongeka chifukwa cha chinyezi), kuchepa kwa madzi pambuyo pa nyengo 1-2.

TPU yolangizidwa (thermoplastic pourethane)

Njira Yothandizira yomwe imagwiritsidwa ntchito m'matumba okwera.
Ubwino:
• Kutalika kwa HH
• Kugonjetsedwa kwambiri ndi abrasion
• Ndalama zabwinoko kwa nylon
• Imagwira bwino ndi misampha yotentha
• Zachilengedwe zotetezeka kuposa pvc
Zoyipa: Mtengo wokwera.

Ngati mukufuna a thumba labwino kwambiri la madzi, Tpu ndiye muyezo wagolide.

PVC KULIMBITSA KWA PVC

Mphepo yamkuntho koma yolemetsa, zachilengedwe, yoletsedwa, yoletsedwa m'magulu ena a Eu.

Chovala cholemera chopanda pake

Kulemera sikumangokhala wopanda madzi.
