Kunzwisisa Kuputsa Simba uye Elongation muPolyester PET Strap

Zviverengo Zviviri Zvinotsanangura Kuita

Paunenge uchiongorora PET tambo (polyester tambo), maviri emuchina zvivakwa akakosha kupfuura chero mamwe: kutyora simba uye kureba. Pamwe chete, vanosarudza kana tambo ichachengetedza mutoro wako, kuchengetedza kushushikana panguva yekufamba, uye kuita zvakavimbika mumidziyo yako. Zvinoenderana neASTM D3950, iyo yakajairwa dhizaini yekusunga tambo, zvese kutyora simba uye kureba zvinofanirwa kuedzwa uye kuoneswa kune yega yega batch yekugadzira.

PaJushuo Packaging , data redu rekugadzira rinoratidza kuti vatengi vanonzwisisa zvivakwa zviviri izvi vanoita sarudzo dziri nani. Gwaro iri rinotsanangura kuti kutyora simba uye kurebesa zvinorevei, mabatiro avanoita, uye mashandisiro avangaita pakusarudza tambo chaiyo yePET.

1. Kuputsa Simba: The Load Capacity Metric

1.1 Chii Chinonzi Kuputsa Simba?

Kutyoka simba (kunonziwo break force kana tensile simba) isimba guru rinogonekwa netambo isati yadambuka. Zvinoenderana neASTM D3950, simba rekupwanya rinoyerwa nekudhonza tambo yemuenzaniso kusvika yatadza, kurekodha simba guru rakawanikwa.

Kuputsa simba kunowanzo kuratidzwa mu:

• Makirogiramu (kg) : Inowanikwa mumisika yeEurope neAsia

• Mapaundi (lbs) : Yakajairika mumisika yekuNorth America

• Newtons (N) : Scientific standard

• Megapascals (MPa) : Material pfuma (force per unit unit)

1.2 Yakajairika Kutyora Simba Range yePET Strap

Zvinoenderana nekutsanangurwa kweindasitiri, PET tambo yekupwanya simba inotangira pa160kg kusvika 1,360kg zvichienderana nehupamhi, ukobvu, uye giredhi:

1.3 Kuti Kupwanya Simba Kunoedzwa sei

Zvinoenderana neASTM D3950, kutyora simba kuyedzwa kunotevera yakamisikidzwa maitiro:

1. Sample kugadzirira: Mumiriri masampuli kubva kukugadzira batch

2. Yekumhanyisa kumhanya: Yakamisikidzwa yekuyedza kumhanya (kazhinji 50mm/min)

3. Chiyero: Ukuru hwesimba pazororo rekodhi

4. Mhedzisiro yemhedzisiro: Inofanirwa kusangana kana kudarika yakatarwa kutyora simba

Zvinyorwa zveJushuo Packaging zvemhando yepamusoro zvinosanganisira kutyora simba rekuyedza mhinduro kune yega yega batch yekugadzira.

2. Elongation: The Stretch Behavior Metric

2.1 Chii chinonzi Elongation?

Elongation (inonziwo elongation at break) imari inotambanudzwa netambo isati yadambuka, inotaridzwa sechikamu chehurefu hwayo hwepakutanga. Sekureva kweASTM D3950, kureba kunoyerwa panguva imwecheteyo yekuyedza iyo inotaridza kutyora simba.

Kune PET strap, elongation pakuputsika inowanzobva ku10% kusvika ku18% , yakanyanya kuderera pane PP strap (12-20%) uye yakanyanya kuderera kupfuura nylon (30%+).

2.2 Sei Elongation Ikakosha

Elongation inokanganisa maitiro anoita tambo pasi pemutoro:

2.3 Maedzo Elongation

Zvinoenderana neASTM D3950, kureba kunoyerwa panguva yekuyedzwa kwekunetseka:

1. Hurefu hwekutanga hwakarekodhwa

2. Tambo yakatambanudzwa kusvika pakutyora

3. Kureba kwekupedzisira panguva yekuzorora kwakanyorwa

4. Elongation inoverengerwa sekuwedzera kwezana

PaJushuo Packaging , data yedu yerabhu inosimbisa kuti PET tambo inogara ichiendesa elongation kukosha mu10-18% renji, zvichienderana negiredhi uye ukobvu.

3. Hukama Pakati Pekuputsa Simba uye Elongation

3.1 The Trade-Off

Kupwanya simba uye kurebesa zvine hukama asi zvakasiyana zvivakwa. Zvinoenderana neiyo zvinhu zvesainzi nheyo, kazhinji pane kutengeserana-kusiyana:

• Kunyanya kutyora simba kazhinji kunouya nekurebesa kwakaderera

• Kurebesa kwepamusoro kazhinji kunoreva kuderera kwesimba rekupwanya

Kuchinjana uku kuripo nekuti molecular orientation -kurongeka kwepolymer cheni iyo inowedzera simba - zvakare inoderedza kugona kwechinhu kutambanudza.

3.2 Nei PET Ichiwana Zvose

PET tambo inowana yakaringana chiyero chepamusoro kutyora simba uye yakaderera kureba kuburikidza nekugadzira kwayo maitiro. Zvinoenderana nezvinyorwa zvepatent pakugadzira tambo, kudzora dhirowa reshiyo panguva yekugadzira inobata zvakananga zvivakwa zvese:

PET tambo inowanzo gadzirwa padhirowa reshiyo inoburitsa yakakwira yekutyoka simba ine yakaderera elongation-yakanaka musanganiswa wekuchengetedza mutoro.

4. Kushanda Zvikumbiro

4.1 Kuchengetedzwa Kwemutoro

Kupwanya simba kunogadzirisa mutoro mukuru uyo ​​tambo inogona kuchengetedza. Zvinoenderana nemaitiro ekuchengetedza, tambo dzinofanirwa kuyerwa inokwana 150% yakakwira kupfuura inotarisirwa mitoro yekushanda kuti igamuchire mitoro yekuvhunduka uye kuparara kwezvinhu.

Muenzaniso kuverenga:

• Mutoro uremu: 500kg

• Inodiwa kuputsa simba: 500kg × 1.5 = 750kg shoma

4.2 Tension Retention

Elongation inokanganisa kuti tambo inochengetedza sei kukakavara nekufamba kwenguva. Yakaderera-elongation PET tambo inochengetedza kushushikana sezvo mitoro inogadzikana, nepo yakakwirira-elongation tambo inogona kuzorora. Kwekutakura kure-kure, kureba kwakaderera kunosarudzwa.

4.3 Equipment Kuenderana

Zvose zviri zviviri zvinokanganisa mashandiro emidziyo. Zvinoenderana nevagadziri vemidziyo, otomatiki tambo michina inoyerwa kune chaiyo yekupwanya simba uye elongation renji. Kushandisa tambo kunze kwemarenji aya kunogona kukonzera nyaya dzekudyisa, kutadza chisimbiso, kana kukuvara kwemidziyo.

5. Mitemo Yekusarudza

5.1 Kufananidza Zvivakwa kune Zvishandiso

5.2 Chengetedzo Factor Mafungiro

Zvinoenderana nemaitiro ekuchengetedza, nguva dzose shandisa chinhu chekuchengetedza:

• Static mitoro : 1.5 × zvishoma

• Dynamic mitoro : 2 × zvishoma

• Zvikumbiro zvakakosha : 3 × inokurudzirwa

5.3 Sample Testing

Zvinoenderana nemhando yemhando, bvunzo yekuyedza inokurudzirwa isati yazara-chiyero kugadzirwa. Edza zvese kutyora kusimba uye kurebesa kuti uone kuti zvakatemwa zvinosangana nezvinodiwa.

Jushuo Packaging inopa masampula ane akanyorwa kutyora simba uye elongation kukosha kwekusimbisa.

Summary

Kupwanya simba uye kurebesa ndiwo maviri akakosha emuchina zvivakwa zvePET tambo . Kupwanya simba kunotemesa mutoro wakakura uyo tambo inogona kuchengetedza, nepo elongation inosarudza kuti tambo inozvibata sei pasi pemutoro. PET strap inowana kuenzana kwakaringana kwekupwanya simba (160-1,360kg) uye yakaderera elongation (10-18%) kuburikidza nekudzora maitiro ekugadzira.

Paunenge uchisarudza PET tambo, funga zvese zviri zviviri zvivakwa pamwe chete: kutyora simba rekutakura mutoro uye chengetedzo chinhu, kurebesa kwetension kuchengetedza uye kukodzera kwekushandisa. Isa shoma shoma 1.5 × kuchengetedza chinhu kune static mitoro uye 2 × kune ine simba mitoro. Pakutakura kureba-kure kana mitoro yakaoma, kureba kwakaderera kunosarudzwa. Kune mitoro inomanikidzika, kurebesa kuri pakati nepakati kunopa kubatwa kwekuvhunduka.

Jushuo Packaging inopa yakazara PET tambo mhinduro ine yakanyorwa kutyora simba uye elongation yakatarwa. Kugona kwedu kugadzira - 4 PET mitsetse yekugadzira ine zviuru makumi maviri zvematani epagore kugona - ive nechokwadi chekuita kunoenderana pane ese akatsanangurwa zviyero. Isu tinopa yakazara bvunzo zvinyorwa nezvese zvinotumirwa uye kutsigira vatengi kuburikidza nekutsanangurwa kusarudzwa.

Kana iwe uchida rubatsiro kunzwisisa kutyora simba uye kurebesa kwePET tambo application, ndapota tumira email kune sales@jushuopackaging.com , uye timu yedu yehunyanzvi ichapa rutsigiro rwemunhu-pamwe.
