Njikwa viscosity na eriri PET: Gịnị kpatara 0.60-0.95 dl/g ji dị mkpa maka ike

Nọmba zoro ezo n'azụ ike eriri PET

Mgbe ndị zụrụ ezipụta Eriri PET ( eriri polyester), ha na-elekarị anya metrik a na-ahụ anya: obosara, ọkpụrụkpụ, na ike mgbaji. Agbanyeghị, arụrụ arụ ọrụ nke eriri emechara bụ nke akọwapụtara nke ọma site na nkọwapụta anaghị ahụ anya nke akụrụngwa: viscosity intrinsic (IV).

Viscosity bụ ihe ọ̀tụ̀tụ̀ arọ molekụla nke resin polyester. Ọ na-ekpebi ogologo n'agbụ polymer na otú ha siri jikọta ibe ha. N'ime ụlọ ọrụ eriri, ebe dị ụtọ maka eriri PET dị elu bụ viscosity nke 0.60 ruo 0.95 dl / g..

Ọ bụrụ na viscosity dị oke ala, ụdọ polymer dị mkpụmkpụ, na-ebute eriri na-enweghị ike ịgbaji ma nwee ike ịgbaji ngwa ngwa. Ọ bụrụ na viscosity dị oke elu, resin na-esi ike ka ọ rụọ ọrụ nke ọma, na-eduga n'ichepụta ntụpọ.

Na ngwugwu Jushuo, data mmepụta anyị na-egosi na idobe njikwa viscosity siri ike n'etiti 0.60 na 0.95 dl/g dị mkpa maka imepụta eriri nke nwere ike dochie ígwè na ngwa ọrụ dị arọ.

1. Kedu ihe bụ viscosity dị n'ime?

1.1 Nkọwa na nha

Intrinsic viscosity (IV) bụ ihe nleba anya nke ike polymer ịgbaba na ngwọta, nke na-ejikọta ya na ịdị arọ ya. Dịka ụkpụrụ sayensị polymer siri dị, a na-atụkarị IV na deciliter kwa gram (dl/g). Maka resin PET ejiri na eriri, nha na-egosi ogo polymerization.

1.2 Gịnị kpatara viscosity ji ada n'oge nhazi

N'oge usoro extrusion, a na-agbaze resin PET na oke okpomọkụ. Dị ka n'ichepụta kemịkal, okpomọkụ na mmiri nwere ike ime ka hydrolysis, na-agbaji polymer chains na ibelata viscosity. Enweghị njikwa kwesịrị ekwesị, eriri emechara nwere ike ịnwe viscosity dị ala karịa akụrụngwa, na-eduga n'ịbelata akụrụngwa akụrụngwa.

2. Ọrụ nke viscosity na ike eriri

2.1 Ike tensile

Ike tensile na-adakọ kpọmkwem na ịdị arọ molekụla. Agbụ polymer ogologo (nke dị elu viscosity) na-emepụta ihe ntinye aka karịa, nke na-eguzogide ịdaba n'okpuru esemokwu. Eriri PET nwere viscosity nke 0.80 dl/g ga-akarị nke ọma eriri emere site na 0.60 dl/g resin n'ihe gbasara ike nkwụsịtụ na nguzogide mmetụta.

2.2 Mgbakwunye na nkwụsi ike

Viscosity na-emetụtakwa ka eriri ahụ si gbatịa. PET nwere viscosity dị elu na-egosipụta mgbake na-agbanwe nke ọma, nke pụtara na ọ na-edobe esemokwu ka oge na-aga ka ibu na-edozi. PET nwere obere viscosity nwere ike gbatịa na-adịgide adịgide, na-eduga n'ibu ibu n'oge njem.

2.3 Nguzogide gburugburu ebe obibi

Dabere na data sayensị ihe onwunwe, viscosity PET dị elu na-eguzogide mmebi UV na ịka nká nke ọma karịa akara ule viscosity dị ala. Nke a na-eme ka eriri ahụ na-edobe ike ya n'oge nchekwa ogologo oge dị n'èzí ma ọ bụ njem n'oké osimiri.

3. Nsonaazụ nke viscosity na-ezighi ezi

3.1 Ọ bụrụ na viscosity dị obere (<0.60 dl/g)

• Eriri mgbawa : eriri ahụ nwere ike ịgbawa ma ọ bụ kewaa n'oge esemokwu.

• Ike nkwụsịtụ dị ala : eriri ahụ na-ada n'okpuru ibu nke eriri akọwapụtara nke ọma nwere ike ijikwa.

• Arụmọrụ na-ekwekọghị ekwekọ : Batch-to-batch dị iche iche na-akpata nkwụsị ahịrị mmepụta.

3.2 Ọ bụrụ na viscosity dị oke elu (> 0.95 dl / g)

• Okwu nhazi : Nnukwu resin viscosity siri ike extrude na gbatịa, na-eduga elu ike oriri na akụrụngwa eyi.

• Isi ike : eriri ahụ nwere ike ịdị oke siri ike iji kwekọọ na ụdị ngwugwu, na-ebelata nkwụsi ike ibu.

4. Ka Jushuo Packaging ji achịkwa viscosity

Na ngwugwu Jushuo, anyị anaghị ahapụ viscosity na ohere. Anyị na-eji teknụzụ Solid State Polymerization (SSP) iji jikwaa ma mee ka viscosity dị mkpa nke resin PET anyị dị.

Dabere na data mmepụta anyị, teknụzụ SSP na-enye anyị ohere ịhazigharị viscosity nke ọma n'ime oke 0.60 ruo 0.95 dl/g. Nke a na-eme ka o sie ike na eriri PET ọ bụla na-enweta ike ike na ịdịte aka. Anyị na-enyocha viscosity site na nnwale ụlọ nyocha siri ike, na-ahụ na eriri emechara na-ewepụta arụmọrụ achọrọ maka ngwa nrụpụta ọrụ dị arọ.

5. Na-enyocha njikwa viscosity Supplier

5.1 Akwụkwọ

Mgbe ị na-ahọrọ ndị na-ebunye eriri PET, jụọ maka nkọwapụta akụrụngwa. Onye na-ebubata ihe a pụrụ ịdabere na ya ga-enye akwụkwọ nke viscosity dị n'ime resin na ihe eji arụ ọrụ eriri emechara. Nghọta a na-egosi na njikwa viscosity bụ akụkụ nke usoro njikwa mma ha.

5.2 Nlele nlele

Rịọ ihe nlele ma nwalee ha. Dị ka omume kacha mma si dị:

1. Nnwale tensile : Chọpụta ike nkwụsị ahụ dabara na nkọwapụta.

2. Nnwale elongation : tụọ ole eriri na-agbatị n'okpuru ibu.

3. Nyocha anya : Lelee maka ntụpọ elu nke nwere ike igosi nhazi adịghị mma.

Nchịkọta

Viscosity intrinsic bụ nkọwapụta zoro ezo nke na-ekpebi ike nke eriri PET (eriri polyester). Ihe kachasị mma nke 0.60 ruo 0.95 dl / g na-eme ka a hụ na ụdọ polymer dị ogologo oge iji nye ike dị elu na mgbake na-agbanwe agbanwe, ebe ọ na-anọgide na-edozi maka mmepụta ihe a pụrụ ịdabere na ya.

Maka ndị na-azụ ahịa, ịghọta viscosity na-enyere aka ịmata ọdịiche dị n'etiti ndị na-ebubata ihe dị elu na ndị na-egbutu akụkụ. Site n'ịkwado njikwa viscosity, ị nwere ike hụ na eriri PET ị zụrụ ga-arụ ọrụ nke ọma na ngwa na-achọsi ike.

Nkwakọ ngwaahịa Jushuo na-eguzo dị ka onye na-emepụta eriri polyester PET ntụkwasị obi gị, na-ebuga azịza strapping plastic dị elu nke na-akwado ihe karịrị afọ iri nke ọkachamara pụrụ iche.
