Kumvetsetsa Kuphwanya Mphamvu ndi Kutalikirana mu Polyester PET Strap

Nambala Ziwiri Zomwe Zimatanthawuza Magwiridwe

Poyesa Chingwe cha PET (chingwe cha poliyesitala), zinthu ziwiri zamakina ndizofunikira kwambiri kuposa zina zilizonse: kuthyola mphamvu ndi kutalika. Onse pamodzi, amawona ngati lamba lingateteze katundu wanu, likhalebe lolimba panthawi ya ulendo, ndikugwira ntchito modalirika pazida zanu. Malinga ndi ASTM D3950, mulingo wokhazikika womangira, mphamvu zonse zosweka komanso kutalika kwake ziyenera kuyesedwa ndikutsimikiziridwa pagulu lililonse lopanga.

Pa Jushuo Packaging , deta yathu yopanga imasonyeza kuti ogula omwe amamvetsa zinthu ziwirizi amapanga zisankho zabwino kwambiri. Bukuli likufotokoza zomwe kuthyola mphamvu ndi kutalika kumatanthauza, momwe amalumikizirana, ndi momwe angagwiritsire ntchito posankha lamba loyenera la PET.

1. Kuthyola Mphamvu: The Load Capacity Metric

1.1 Kodi Kuphwanya Mphamvu Ndi Chiyani?

Kuthyoka mphamvu (yomwe imatchedwanso break force kapena tensile mphamvu) ndi mphamvu yayikulu yomwe chingwe chimatha kupirira chisanaduke. Malingana ndi ASTM D3950, kusweka mphamvu kumayesedwa ndi kukoka chitsanzo cha chingwe mpaka kulephera, kujambula mphamvu yaikulu yomwe imapezeka.

Mphamvu yakusweka imawonetsedwa mu:

• Ma kilogalamu (kg) : Wamba m'misika yaku Europe ndi Asia

• Mapaundi (lbs) : Odziwika m'misika yaku North America

• Newtons (N) : Muyezo wa sayansi

• Megapascals (MPa) : Katundu wazinthu (mphamvu pagawo lililonse)

1.2 Mtundu Wamphamvu Wosweka Wamphamvu wa PET Strap

Malinga ndi mafotokozedwe amakampani, mphamvu zothyola zingwe za PET zimachokera ku 160kg mpaka 1,360kg kutengera m'lifupi, makulidwe, ndi giredi:

1.3 Momwe Kuphwanya Mphamvu Kumayesedwera

Malinga ndi ASTM D3950, kuyesa kwamphamvu kumatsata njira yokhazikika:

1. Kukonzekera kwachitsanzo: Zitsanzo zoimira kuchokera ku gulu lopanga

2. Liwiro loyesa: Liwiro loyezetsa lokhazikika (nthawi zambiri 50mm / min)

3. Muyezo: Mphamvu yochuluka kwambiri pa nthawi yopuma yolembedwa

4. Kuwunika kwa zotsatira: Iyenera kukwaniritsa kapena kupitilira mphamvu yosweka yomwe yatchulidwa

Zolemba zamtundu wa Jushuo Packaging zikuphatikiza kuphwanya zotsatira zoyesa mphamvu pagulu lililonse lopanga.

2. Elongation: The Stretch Behavior Metric

2.1 Kodi Elongation ndi chiyani?

Elongation (yomwe imatchedwanso kuti elongation panthawi yopuma) ndi kuchuluka kwa chingwe chomwe chimatambasulidwa chisanaduke, chomwe chimafotokozedwa ngati gawo la kutalika kwake koyambirira. Malinga ndi ASTM D3950, elongation imayesedwa panthawi yoyeserera yomwe imatsimikizira kusweka mphamvu.

Kwa chingwe cha PET, kutalika kwa nthawi yopuma kumachokera ku 10% mpaka 18% , kutsika kwambiri kuposa PP (12-20%) ndi kutsika kwambiri kuposa nayiloni (30%+).

2.2 Chifukwa Chake Kutalikira Kuli Kofunikira

Elongation imakhudza momwe chingwe chimakhalira pansi pa katundu:

2.3 Momwe Elongation Imayesedwa

Malinga ndi ASTM D3950, elongation imayesedwa pakuyesa kolimba:

1. Kutalika koyambirira kwajambulidwa

2. Lamba anatambasula mpaka yopuma

3. Kutalika komaliza pa nthawi yopuma kulembedwa

4. Elongation imawerengedwa ngati kuchuluka kwa kuchuluka

Pa Jushuo Packaging , deta yathu ya labu imatsimikizira kuti PET strap imapereka nthawi zonse miyeso ya elongation mu 10-18%, malingana ndi kalasi ndi makulidwe.

3. Ubale Pakati pa Kusweka Mphamvu ndi Kutalikirana

3.1 Kusinthana kwachuma

Kusweka mphamvu ndi elongation ndi zogwirizana koma katundu osiyana. Malinga ndi mfundo za sayansi ya zinthu, nthawi zambiri pamakhala kusinthanitsa:

• Mphamvu yosweka kwambiri nthawi zambiri imabwera ndi kutalika kochepa

• Kutalika kwakukulu nthawi zambiri kumatanthauza kutsika kwamphamvu

Kusinthana uku kulipo chifukwa kukhazikika kwa ma cell - kulumikizana kwa maunyolo a polima omwe amawonjezera mphamvu - kumachepetsanso kuthekera kwazinthu kutambasula.

3.2 Chifukwa Chake PET Imakwaniritsa Zonse ziwiri

Chingwe cha PET chimakwaniritsa mphamvu zosweka kwambiri komanso kutalika kochepa kudzera mukupanga kwake. Malinga ndi zolemba za patent pakupanga zingwe, kuwongolera chiŵerengero cha kukoka pakupanga kumakhudza mwachindunji zinthu zonse ziwiri:

Chingwe cha PET nthawi zambiri chimapangidwa motengera mphamvu zomwe zimapereka mphamvu zosweka kwambiri komanso kutalika kocheperako - kuphatikiza koyenera kwa chitetezo cha katundu.

4. Ntchito Zothandiza

4.1 Chitetezo cha katundu

Kuthyola mphamvu kumatsimikizira kuchuluka kwakukulu komwe chingwe chingatetezedwe. Malinga ndi miyezo yachitetezo, zomangira zimayenera kuyesedwa osachepera 150% kuposa zomwe zimayembekezeredwa kuti zigwirizane ndi katundu wodabwitsa komanso kuwonongeka kwa zinthu.

Chitsanzo chowerengera:

• Kulemera kwa katundu: 500kg

• Amafunika kuswa mphamvu: 500kg × 1.5 = 750kg osachepera

4.2 Kusunga Manoni

Elongation imakhudza momwe lamba limakhalira ndi zovuta pakapita nthawi. Chingwe chotalikirapo cha PET chimasunga kupsinjika pamene katundu ukukhazikika, pomwe zingwe zotalikirapo zimatha kupumula. Kwa kutumiza mtunda wautali, kutalika kocheperako kumakondedwa.

4.3 Kugwirizana kwa Zida

Zonse ziwiri zimakhudza magwiridwe antchito a zida. Malinga ndi opanga zida, makina omangira okha amawunikidwa kuti azitha kusweka komanso kutalika kwake. Kugwiritsa ntchito zingwe kunja kwa mindandanda iyi kungayambitse vuto la chakudya, kulephera kwa chisindikizo, kapena kuwonongeka kwa zida.

5. Malangizo Osankha

5.1 Kufananiza Katundu ndi Mapulogalamu

5.2 Zoganizira za Chitetezo

Malinga ndi miyezo yachitetezo, nthawi zonse muzigwiritsa ntchito chitetezo:

• Katundu wosasunthika : 1.5 × osachepera

• Katundu wamphamvu : 2 × osachepera

• Ntchito zovuta : 3 × analimbikitsa

5.3 Kuyesa Zitsanzo

Malinga ndi miyezo yapamwamba, kuyesa kwachitsanzo kumalimbikitsidwa musanayambe kupanga zonse. Yesani mphamvu zonse zosweka komanso kutalika kuti muwonetsetse kuti zofunikira zimakwaniritsa zofunikira.

Jushuo Packaging imapereka zitsanzo zokhala ndi zolembedwa zamphamvu zosweka komanso ma elongation kuti zitsimikizidwe.

Chidule

Kuthyola mphamvu ndi kutalika ndizinthu ziwiri zofunika kwambiri zamakina a chingwe cha PET . Kuthyola mphamvu kumapangitsa kuti chingwecho chitetezeke, pamene elongation imatsimikizira momwe chingwecho chimakhalira pansi pa katundu. Chingwe cha PET chimakwaniritsa mphamvu zosweka kwambiri (160-1,360kg) komanso kutalika kwapang'onopang'ono (10-18%) kudzera munjira zoyendetsedwa bwino.

Posankha chingwe cha PET, ganizirani zonse ziwiri pamodzi: kuthyola mphamvu ya katundu ndi chitetezo, kutalika kwa kusungirako kukanikiza ndi kuyenerera kwa ntchito. Ikani zosachepera 1.5 × chitetezo chinthu pa katundu static ndi 2 × pa katundu wamphamvu. Pakutumiza mtunda wautali kapena katundu wokhazikika, kutalika kocheperako kumakondedwa. Kwa katundu wophatikizika, kukweza pang'ono kumapereka mayamwidwe odabwitsa.

Jushuo Packaging imapereka mayankho omveka bwino a zingwe za PET okhala ndi zolembedwa zosweka komanso mafotokozedwe akutali. Kuthekera kwathu pakupanga - mizere 4 yopanga PET yokhala ndi matani 20,000 pachaka-tiwonetsetse kuti magwiridwe antchito amakhazikika pamiyeso yonse yodziwika. Timapereka zolemba zonse zoyeserera ndi zotumiza zilizonse ndikuthandizira makasitomala kudzera pakusankha kwatsatanetsatane.

Ngati mukufuna kuthandizidwa kumvetsetsa kuthyola mphamvu ndi kutalika kwa ntchito yanu yachingwe cha PET, chonde tumizani imelo kwa sales@jushuopackaging.com , ndipo gulu lathu la akatswiri lidzapereka chithandizo chimodzi-mmodzi.
