Ịghọta mgbawa ike na mmụba na eriri polyester PET

Ọnụọgụ abụọ nke na-akọwa arụmọrụ

Mgbe a na-enyocha Eriri PET (eriri polyester), ihe eji arụ ọrụ abụọ dị mkpa karịa ndị ọzọ: ike na-agbaji na elongation. Ha jikọtara ọnụ, ha na-ekpebi ma eriri ọ ga-echekwa ibu gị, na-enwe nchekasị n'oge njem, ma rụọ ọrụ nke ọma na akụrụngwa gị. Dabere na ASTM D3950, ọkọlọtọ nkọwapụta maka strapping, ma na-agbaji ike na elongation ga-anwale ma kwenye maka ọ bụla mmepụta ogbe.

Na Jushuo Packaging , data mmepụta anyị na-egosi na ndị na-azụ ahịa ghọtara ihe abụọ a na-eme mkpebi nkọwa ka mma. Ntuziaka a na-akọwa ihe nbibi ike na elongation pụtara, ka ha na-emekọrịta ihe, na otu esi eji ha maka ịhọrọ eriri PET ziri ezi.

1. Ike na-agbaji: Metric Capacity Metric

1.1 Kedu ihe na-agbaji ike?

Njiji ike (nke a na-akpọkwa ike nkwụsịtụ ma ọ bụ ike nkwụsị) bụ ike kachasị elu nke eriri nwere ike idi tupu agbaji. Dị ka ASTM D3950 si kwuo, a na-atụ ike imebi site na ịdọrọ eriri eriri ruo mgbe ọ daa, na-edekọ ike kacha enweta.

A na-egosipụtakarị ike mgbaji na:

• Kilogram (kg) : A na-ahụkarị na ahịa Europe na Asia

• Pound (lbs) : A na-ahụkarị na ahịa North America

• Newtons (N) : ọkọlọtọ sayensị

• Megapascals (MPa) : Ihe onwunwe (ike kwa mpaghara otu)

1.2 Oke mgbawa ike maka eriri PET

Dabere na nkọwapụta ụlọ ọrụ, eriri PET na-agbaji ike sitere na 160kg ruo 1,360kg dabere na obosara, ọkpụrụkpụ, na ọkwa:

1.3 Otu esi anwale ike ịgbaji

Dị ka ASTM D3950 si kwuo, nleba anya ike na-agbaso usoro ahaziri ahazi:

1. Nkwadebe ihe nlere anya: ihe nnochite anya sitere na ogbe mmepụta

2. Ọsọ nnwale: Ọsọ nnwale ahaziri ahazi (na-abụkarị 50mm/min)

3. Nleta: Edekọbara ike kachasị na nkwụsịtụ

4. Ntụle nsonaazụ: Ga-ezute ma ọ bụ gafere ike nbibi akọwapụtara

Akwụkwọ mma Jushuo Packaging gụnyere imebi rịzọlt nnwale maka ogbe mmepụta ọ bụla.

2. elongation: The Stretch Behavior Metric

2.1 Gịnị bụ Elongation?

Elongation (nke a na-akpọ elongation na nkwụsịtụ) bụ ego nke eriri na-agbatị tupu agbaji, egosipụtara dị ka pasent nke ogologo mbụ ya. Dị ka ASTM D3950 si kwuo, a na-atụ elongation n'oge otu ule tensile na-ekpebi ike ịgbaji.

Maka eriri PET, elongation na nkwụsịtụ na-adịkarị site na 10% ruo 18% , nke dị ala karịa eriri PP (12-20%) yana dị ala karịa naịlọn (30%+).

2.2 Gịnị kpatara elongation ji dị mkpa

Mgbatị na-emetụta ka eriri na-eme n'okpuru ibu:

2.3 Otu esi anwale elongation

Dabere na ASTM D3950, a na-atụ elongation n'oge ule tensile:

1. Edere ogologo izizi

2. Eriri agbatị ruo mgbe ezumike

3. Edekọbara ogologo ikpeazụ na nkwụsịtụ

4. A gbakọrọ elongation ka pasentị na-abawanye

Na nkwakọ ngwaahịa Jushuo , data ụlọ nyocha anyị na-akwado na eriri PET na-enyekarị ụkpụrụ elongation na nso 10-18%, dabere na ọkwa na ọkpụrụkpụ.

3. Mmekọrịta dị n'etiti ịgbaji ike na elongation

3.1 Azụmahịa ahịa

Agbaji ike na elongation metụtara ma ihe dị iche iche. Dị ka ụkpụrụ sayensị ihe onwunwe si dị, a na-enwekarị mgbanwe:

• Ike mgbaji dị elu na-abịakarị na elongation dị ala

• Elu elongation na-apụtakarị ike ịkụda ala

Azụmahịa a dị n'ihi na molecular nghazi — nhazi nke ụdọ polymer nke na-abawanye ike—na-ebelatakwa ikike nke ihe nwere ịgbatị.

3.2 Ihe kpatara PET ji enweta ihe abụọ a

Eriri PET na-enweta nguzozi kachasị mma nke ike mgbawa dị elu yana elongation dị ala site na usoro nrụpụta ya. Dị ka akwụkwọ ikike ikike na mmepụta strapping si kwuo, ịchịkwa nha nha n'oge nrụpụta na-emetụta ihe abụọ a:

A na-arụpụta eriri PET na nha nha nke na-ebuga ike na-agbaji dị elu yana elongation dị ala - ngwakọta dị mma maka nchekwa ibu.

4. Ngwa bara uru

4.1 Nchekwa ibu

Ike mgbaji na-ekpebi ibu kachasị nke eriri nwere ike idobe ya. Dị ka ụkpụrụ nchekwa si dị, eriri kwesịrị ka ọ dịkarịa ala 150% dị elu karịa ibu ọrụ a tụrụ anya ya iji nabata ibu ujo na mmebi ihe.

Ngụkọ atụ:

• Ibu ibu: 500kg

• Ike mgbaji achọrọ: 500kg × 1.5 = 750kg kacha nta

4.2 Njide erughị ala

Ogologo oge na-emetụta ka eriri na-ejigide esemokwu ka oge na-aga. Eriri PET dị ala na-edobe esemokwu ka ibu na-edozi, ebe eriri elongation dị elu nwere ike zuru ike. Maka mbupu dị anya, a na-ahọrọ elongation dị ala.

4.3 Ngwa ndakọrịta

Njirimara abụọ a na-emetụta arụmọrụ akụrụngwa. Dị ka ndị na-emepụta ngwá ọrụ si kwuo, a na-ahazi igwe eriri akpaka maka ike na-agbaji kpọmkwem na oke elongation. Iji eriri na mpụga oke ndị a nwere ike ibute nsogbu nri, ọdịda akara, ma ọ bụ mmebi akụrụngwa.

5. Ntuziaka nhọrọ

5.1 Ngwa dakọtara na ngwa

5.2 Ntụle ihe gbasara nchekwa

Dịka ụkpụrụ nchekwa siri dị, tinye ihe nchekwa mgbe niile:

• Ibu static : 1.5× kacha nta

• Ibu dị ike : 2× kacha nta

• Ngwa dị egwu : 3× kwadoro

5.3 Nlele nlele

Dịka ụkpụrụ dị mma si dị, a na-atụ aro ịnwale nlele tupu mmepụta zuru oke. Nwalee ma na-agbaji ike na elongation iji hụ na nkọwa zuru ezu chọrọ.

Nkwakọ ngwaahịa Jushuo na-enye ihe nlele nwere ike imebi akwụkwọ yana ụkpụrụ elongation maka nkwenye.

Nchịkọta

Mgbaji ike na elongation bụ ihe eji arụ ọrụ abụọ kachasị mkpa nke eriri PET . Ịgbaji ike na-ekpebi ibu kachasị elu nke eriri nwere ike ịchekwa, ebe elongation na-ekpebi otú eriri ahụ si eme n'okpuru ibu. Eriri PET na-enweta nguzozi kachasị mma nke ike mgbawa dị elu (160-1,360kg) na elongation dị ala (10-18%) site na usoro nrụpụta a na-achịkwa.

Mgbe ị na-ahọrọ eriri PET, tụlee ihe abụọ a ọnụ: agbaji ike maka ikike ibu na ihe nchekwa, elongation maka njigide esemokwu na ntinye ngwa. Tinye ihe nchekwa opekata mpe 1.5 × maka ibu static yana 2 × maka ibu dị ike. Maka mbupu ogologo ma ọ bụ ibu siri ike, a na-ahọrọ elongation dị ala. Maka ibu ndị nwere ike ịgbakọ, elongation na-agafeghị oke na-enye nnabata ujo.

Nkwakọ Jushuo na-enye azịza eriri PET zuru oke yana ike imebi akwụkwọ yana nkọwa elongation. Ike nrụpụta anyị - ahịrị mmepụta PET 4 nwere ikike kwa afọ 20,000 - hụ na arụmọrụ na-agbanwe agbanwe n'akụkụ niile akọwapụtara. Anyị na-enye akwụkwọ nyocha zuru oke na mbupu ọ bụla yana nkwado ndị ahịa site na nhọrọ nkọwapụta.

Ọ bụrụ na ịchọrọ enyemaka ịghọta nbibi ike na elongation maka ngwa eriri PET gị, biko zigara email na ya sales@jushuopackaging.com , na ndị otu ọkachamara anyị ga-enye nkwado otu onye.
