Kedu ihe a ga-elebara anya na mmepụta nke ihe polyethylene a chlorine?

Ọtụtụ mmadụ amaghị ihe gbasara polyethylene a na-akpọ chlorine, dịka aha ya si kwuo, ọtụtụ mmadụ kwesịrị ịhụ naanị na ọ bụ ihe kemịkalụ. O nwere usoro a na-akpọ extrusion molding, nke ka dị oke mkpa n'usoro mmepụta. Yabụ taa, gịnị ka anyị kwesịrị ilebara anya n'oge usoro extrusion molding nke ngwaahịa a? Polyvinyl chloride a na-akpọ chlorine

1. N'ime usoro ihe eji emepụta paịpụ, a ga-elebara nhọrọ nke ihe ndị na-eme ka ihe sie ike na ihe ndị ọzọ na-enyere aka nhazi anya, na-elekwasị anya na ime ka mmụba nke mmiri ịgbaze na ime ka ihe ndị e ji emepụta ihe dịkwuo mma. Ọ bụrụ na ọ dị mkpa, a ga-ebu ụzọ gwakọta ihe ndị e ji emepụta ihe, a ga-ewerekwa obere ihe nlele maka nnwale. Ọ bụrụ na enweghị mgbanwe agba ma ọ bụ ihe na-emebi ihe doro anya na igbe ọkọnọ 230 ℃ ruo awa abụọ, ọ na-egosi na nhọrọ nke ihe ndị e ji emepụta ihe ndị ọzọ dị mma karịa.

2. Okpomọkụ usoro ịkpụzi ihe nke ihe polyvinyl chloride a chlorine nwere dị ntakịrị elu karịa nke paịpụ PVC. Mana ekwesịrị ịmara na mgbanwe njikwa okpomọkụ enweghị ike ịgafe ± 5 ℃.

3. N'oge mmepụta nke paịpụ CPVC, ọ bụrụ na e nwere nkwụsị ọkụ eletrik, nsogbu akụrụngwa, ihe ịrịba ama nke ire ere ihe, ma ọ bụ anwụrụ ọkụ na-esi n'ọnụ ebu pụta, a ga-akwụsị inye ihe ndị dị na barel igwe ozugbo. A ga-eji resin PVC wepụ ihe agbaze CPVC na barel igwe na ebu, wee kwụsị igwe ahụ iji dozie nsogbu ahụ.

4. Tupu e tinye resin ahụ n'ọrụ, a ga-akpọnwụ ya ma gwọọ ya n'ime igbe ọkụ 80 ℃ ruo awa 2-4. Ọ bụrụ na ọ dị mkpa, a ga-eji sieve mesh 40 hichaa ihe ndị a gwakọtara nke ọma otu ugboro, wee tinye ya n'ime hopper extruder maka mmepụta.

5. Gas HCl nke a na-ewepụta n'oge mgbawa nke CPVC na-emerụ ahụike mmadụ ahụ, a kwesịkwara ilebara ikuku dị n'ebe a na-emepụta ihe anya.

6. Igwe mwụda, skru, na ihe gbazere agbaze nke na-agafe n'ime ebu ịkpụzi eji emepụta resin CPVC ga-enwerịrị ọgwụgwọ mgbochi ire ere iji mee ka akụkụ akụrụngwa dị ogologo oge.

N'ime usoro mmepụta ihe ahụ, usoro ịkpụzi ihe e ji chlorine polyvinyl chloride emepụta ka siri ike. N'ezie, ọ dị mkpa ịhọrọ ngwaahịa kwesịrị ekwesị mgbe ị na-eji ya n'ọnọdụ ụfọdụ, anyị kwesịkwara ịtụle nke ọma etu esi eji ya iji mee ka ojiji ya dịkwuo irè.
