Gusobanukirwa Kumena Imbaraga no Kurambura muri Polyester PET

Imibare ibiri isobanura imikorere

Mugihe cyo gusuzuma PET umugozi (polyester strap), ibintu bibiri byubukanishi bifite akamaro kurenza ibindi: kumena imbaraga no kuramba. Hamwe na hamwe, bamenya niba umukandara uzarinda umutwaro wawe, ugakomeza impagarara mugihe cyo gutambuka, kandi ugakora neza mubikoresho byawe. Dukurikije ASTM D3950, ibisobanuro bisanzwe byo gukenyera, imbaraga zo kumena no kuramba bigomba kugeragezwa no kugenzurwa kuri buri cyiciro.

Muri Jushuo Packaging , amakuru yumusaruro yerekana ko abaguzi bumva iyi mitungo yombi bafata ibyemezo byiza byo gusobanura. Aka gatabo gasobanura icyo kumena imbaraga no kurambura bisobanura, uburyo bikorana, nuburyo bwo kubikoresha muguhitamo neza PET.

1. Kumena imbaraga: Ibipimo byubushobozi bwumutwaro

1.1 Kumena imbaraga ni iki?

Kumena imbaraga (nanone bita break force cyangwa tensile strength) nimbaraga ntarengwa umukandara ushobora kwihanganira mbere yo kumeneka. Ukurikije ASTM D3950, imbaraga zo kumeneka zipimwa no gukwega icyitegererezo kugeza igihe binaniwe, kwandika imbaraga ntarengwa zagezweho.

Kumena imbaraga mubisanzwe bigaragarira muri:

• Kilogramu (kg) : Bisanzwe mumasoko yuburayi na Aziya

• Ibiro (lb) : Bisanzwe mumasoko yo muri Amerika ya ruguru

• Newtons (N) : Ubumenyi bwa siyansi

• Megapascals (MPa) : Umutungo wibikoresho (imbaraga kuri buri gice)

1.2 Ibisanzwe Kumena Imbaraga Urwego rwa PET

Ukurikije ibisobanuro byinganda, imbaraga za PET zo kumeneka zingana kuva 160kg kugeza 1,360kg bitewe nubugari, ubunini, n amanota:

1.3 Uburyo bwo Kumena Imbaraga

Ukurikije ASTM D3950, kumena imbaraga zipima bikurikiza inzira isanzwe:

1. Icyitegererezo cyintangarugero: Ingero zihagarariye kuva mubikorwa

2. Umuvuduko wikizamini: Umuvuduko wikizamini gisanzwe (mubisanzwe 50mm / min)

3. Igipimo: Imbaraga ntarengwa zo kuruhuka zanditswe

4. Isuzuma ryibisubizo: Ugomba guhura cyangwa kurenza imbaraga zagaragaye

Jushuo Packaging yujuje ibyangombwa ikubiyemo kumena ibisubizo byikizamini kuri buri cyiciro.

2. Kurambura: Ibipimo by'imyitwarire irambuye

2.1 Kurambura ni iki?

Kurambura (nanone byitwa kurambura kuruhuka) nigitigiri umugozi urambuye mbere yo kumeneka, ugaragazwa nkijanisha ryuburebure bwumwimerere. Ukurikije ASTM D3950, kuramba bipimwa mugihe kimwe cyikizamini kigena imbaraga zo kumena.

Kumugozi wa PET, kurambura kuruhuka mubisanzwe kuva kuri 10% kugeza kuri 18% , munsi cyane ugereranije na PP (12-20%) kandi munsi ya nylon (30% +).

2.2 Impamvu kurambura bifite akamaro

Kurambura bigira ingaruka kuburyo umukandara witwara munsi yumutwaro:

2.3 Ukuntu kuramba kugeragezwa

Ukurikije ASTM D3950, uburebure burapimwa mugihe cyo kwipimisha:

1. Uburebure bwambere bwanditse

2. Umugozi urambuye kugeza uruhutse

3. Uburebure bwanyuma kuruhuka bwanditse

4. Kurambura kubarwa nkijanisha ryiyongera

Kuri Jushuo Gupakira , amakuru yacu ya laboratoire yemeza ko umugozi wa PET uhora utanga indangagaciro ndende hagati ya 10-18%, bitewe nurwego n'ubunini.

3. Isano iri hagati yo kumena imbaraga no kuramba

3.1 Ubucuruzi

Kumena imbaraga no kuramba bifitanye isano ariko ibintu bitandukanye. Ukurikije amahame ya siyansi yibintu, akenshi habaho gucuruza:

• Imbaraga zo kumena cyane akenshi zizanwa no kuramba

• Kurambura cyane bisobanura imbaraga zo kumena imbaraga

Ubu bucuruzi burahari kubera icyerekezo cya molekulari - guhuza iminyururu ya polymer byongera imbaraga-nabyo bigabanya ubushobozi bwibikoresho byo kurambura.

3.2 Kuki PET igera kuri byombi

PET umugozi ugera kuburinganire bwiza bwimbaraga zo kumeneka no kuramba mukoresheje inzira yacyo. Ukurikije ibitabo by'ipatanti ku bijyanye no guhambira umusaruro, kugenzura igipimo cyo gushushanya mu gihe cyo gukora bigira ingaruka ku mitungo yombi:

PET ikariso ikorwa muburyo bwo gushushanya itanga imbaraga zo kumeneka hamwe no kuramba gake - uburyo bwiza bwo guhuza umutekano.

4. Gushyira mu bikorwa

4.1 Umutwaro Umutwaro

Kumena imbaraga bigena umutwaro ntarengwa umukandara ushobora gutekana. Ukurikije ibipimo byumutekano, gukenyera bigomba gupimwa byibuze hejuru ya 150% kurenza imizigo iteganijwe kugirango ikemure imitwaro ihungabana no kwangirika kwibintu.

Urugero rwo kubara:

• Ibiro biremereye: 500kg

• Ingufu zisabwa zisabwa: 500kg × 1.5 = 750kg byibuze

4.2 Kugumana impagarara

Kurambura bigira ingaruka kuburyo umukandara ukomeza guhagarika umutima mugihe runaka. Kurambura-PET umukandara ukomeza impagarara nkuko imitwaro ikemuka, mugihe imishumi-ndende irashobora kuruhuka. Kubirometero ndende byoherezwa, kurambura hasi birahitamo.

4.3 Guhuza ibikoresho

Imitungo yombi igira ingaruka kumikorere yibikoresho. Nk’uko abakora ibikoresho babivuga, imashini zipakurura zikoresha zahinduwe kugirango ziveho imbaraga zidasanzwe. Gukoresha umukandara hanze yiyi ntera birashobora gutera ibibazo byo kugaburira, kunanirwa kashe, cyangwa kwangiza ibikoresho.

5. Amabwiriza yo Guhitamo

5.1 Guhuza Ibiranga Porogaramu

5.2 Ibitekerezo byumutekano

Ukurikije ibipimo byumutekano, burigihe shyira mubikorwa umutekano:

• Imizigo ihagaze : 1.5 × byibuze

• Imizigo idasanzwe : 2 × byibuze

• Porogaramu zingenzi : 3 × zisabwa

5.3 Ikizamini Cyitegererezo

Ukurikije ubuziranenge, gupima icyitegererezo birasabwa mbere yumusaruro wuzuye. Gerageza byombi kumeneka no kurambura kugirango umenye neza ibisabwa.

Gupakira Jushuo itanga ingero hamwe ninyandiko zerekana imbaraga hamwe no kuramba kugirango bigenzurwe.

Incamake

Kumena imbaraga no kuramba nibintu bibiri byingenzi byubukanishi bwa PET . Kumena imbaraga bigena umutwaro ntarengwa umukandara ushobora gutekana, mugihe kuramba bigena uko umukandara witwara munsi yumutwaro. PET umugozi ugera kuburinganire bwiza bwimbaraga nyinshi (160-1,360kg) hamwe no kuramba (10-18%) binyuze mubikorwa bigenzurwa.

Mugihe uhitamo umugozi wa PET, tekereza kubintu byombi hamwe: kumena imbaraga kubushobozi bwumutwaro nibintu byumutekano, kurambura kugumana impagarara hamwe nibisabwa. Koresha byibuze 1.5 factor ibintu byumutekano kumitwaro ihagaze na 2 × kumitwaro yingirakamaro. Kubirometero birebire byoherezwa cyangwa imitwaro ikaze, kurambura hasi birahitamo. Kubintu byoroshye kugabanuka, kurambura biringaniye bitanga ihungabana.

Jushuo Gupakira itanga ibisubizo byuzuye bya PET hamwe nibisobanuro byerekana imbaraga hamwe no kuramba. Ubushobozi bwacu bwo gukora-4 PET imirongo yumusaruro ifite toni 20.000 yumwaka-itanga imikorere ihamye mubipimo byose byagenwe. Dutanga ibizamini byuzuye hamwe nibyoherejwe kandi dushyigikire abakiriya binyuze muguhitamo ibisobanuro.

Niba ukeneye ubufasha bwunvikana kumeneka no kuramba kubisabwa bya PET, nyamuneka ohereza imeri kuri sales@jushuopackaging.com , hamwe nitsinda ryacu ryumwuga rizatanga inkunga kumuntu umwe.
