Usoro mmepụta nke eriri PVC:

Ịgwakọta → igwakorita → extrusion granulation → extrusion akpụ → traction → coiling → nkwakọ → àgwà nnyocha → okokụre ngwaahịa

1. Igwakorita ihe

A na-atụle ụdị akụrụngwa niile nke ọma ma tinye ya na kneader n'usoro.Usoro nri: PVC resin, plasticizer, stabilizer, mmanu mmanu.Mgbe okpomọkụ ruru 100 ~ 110 ℃, ihe nwere ike hapụ.

2.extrusion granulation

Usoro a iji chịkwaa okpomọkụ, ihe kasị elu n'ókè nke ihe okpomọkụ kwesịrị ịchịkwa na elu karịa agbaze okpomọkụ nke ihe onwunwe, ala karịa extrusion ịkpụzi okpomọkụ, ya bụ, n'etiti 155 ~ 160 ℃.Granulation kwesịrị imezu nzube nke ngwakọta zuru ezu na plasticization mbụ.

Ọnọdụ okpomọkụ nke mpaghara ọ bụla nke granulator bụ nke a:

Mpaghara nke 80 ~ 90 ℃;Mpaghara nke 130 ~ 140 ℃;Mpaghara atọ 140 ~ 150 ℃;Malite na 150 ~ 160 ℃.

3. extrusion tube akpụ

Okpomọkụ nke extrusion tube akpụ dị ntakịrị elu.N'ozuzu, nghọta nke ọkpọkọ metụtara okpomọkụ na-emepụta.N'ebe ụfọdụ okpomọkụ, nghọta dị elu nke okpomọkụ dị mma, na nke ọzọ.N'otu oge ahụ, ọsọ traction na ọsọ jụrụ oyi ga-emetụta nghọta nke ọkpọkọ.Ọsọ traction dị ntakịrị karịa, ngwa ngwa jụrụ oyi na-adị ngwa ngwa, na nghọta nke ọkpọkọ dị mma.Ọsọ traction bụ n'ozuzu 10% ~ 15% ngwa ngwa karịa extrusion ọsọ.A na-eji mmiri oyi na-eme ka ọ dị jụụ nke eriri na-egbuke egbuke na mmiri oyi n'oge anwụ nke imi wee mee ka ọ dị jụụ na tank mmiri.

Okpomọkụ nke mpaghara ọ bụla nke ịkpụzi extrusion bụ nke a:

Mpaghara 1:90 ℃;Mpaghara abụọ 140 degrees 5 ℃;Mpaghara atọ 160 degrees 5 ℃;Mpaghara anọ 170 degrees 5 ℃.

4. PVC sooks extrusion nlezianya anya:

1. ozugbo na ntụ ntụ extrusion ịkpụzi, okpomọkụ nke extruder bụ banyere 5 ℃ ala karịa na granular ihe onwunwe.

2. Na mgbakwunye na nke nta dayameta (φ60mm n'okpuru) nke tube oghere jụrụ adịghị mkpa ka a fụọ n'ime abịakọrọ ikuku, ibu dayameta nke tube oghere jụrụ ga-ịfụ n'ime tube abịakọrọ ikuku, iji hụ na izi ezi na nkwụsi ike nke tube dayameta size.Lezienụ anya na nrụgide kwụsiri ike nke ikuku abịakọrọ.

3. Lezienụ anya na nkwụsi ike nke ngwa ngwa traction ma zere mgbanwe nke dayameta ọkpọkọ ma ọ bụ mgbidi mgbidi kpatara nhụsianya traction.

4. Ọ bụrụ na igwe na-emechi ogologo oge, a ghaghị ịkwasa ya ma kpochaa ya iji zere nsogbu ire ere.
