Kedu ihe ekwesịrị ịṅa ntị na mkpụzi extrusion nke ihe polyethylene chlorinated?

Ọtụtụ ndị amachaghị maka polyethylene chlorinated, na dị ka aha ahụ na-egosi, ọtụtụ ndị mmadụ kwesịrị ịhụ naanị na ọ bụ ihe kemịkal. Ọ nwere usoro a na-akpọ extrusion molding, nke ka dị ezigbo mkpa na usoro mmepụta. Ya mere, taa, gịnị ka anyị kwesịrị ịṅa ntị na n'oge extrusion ịkpụzi usoro nke ngwaahịa a? Chlorinated polyvinyl chloride

1. N'ime usoro ihe eji eme ihe maka ịmepụta ọkpọkọ, a ga-akwụ ụgwọ nlebara anya na nhọrọ nke stabilizers na ihe enyemaka nhazi ndị ọzọ, na isi ihe na-elekwasị anya n'ịkwalite mmụba nke mmiri mmiri na-agbaze ma na-eme ka nkwụsi ike nke okpomọkụ nke akụrụngwa. Ọ bụrụ na ọ dị mkpa, enwere ike ibu ụzọ gwakọta ihe ndị ahụ, enwere ike iwere obere nlele maka nnwale. Ọ bụrụ na ọ dịghị ihe doro anya discoloration ma ọ bụ decomposition phenomen na 230 ℃ ọkọnọ igbe maka 2 awa, ọ na-egosi na nhọrọ nke inyeaka ihe bụ ihe ezi uche.

2. The extrusion ịkpụzi usoro okpomọkụ nke chlorinated polyvinyl chloride ihe dịtụ elu karịa nke PVC ọkpọkọ. Ma, ekwesịrị iburu n'obi na mgbanwe njikwa okpomọkụ enweghị ike gafere ± 5 ℃.

3. N'oge mmepụta nke ọkpọkọ CPVC, ọ bụrụ na enwere mbelata ọkụ, akụrụngwa akụrụngwa, ihe ịrịba ama nke ire ere ihe na-agbaze, ma ọ bụ anwụrụ ọkụ na-esi n'ọnụ ebu pụta, a ga-akwụsị inyefe ihe na gbọmgbọm igwe. Ekwesịrị iji resin PVC wepụ ihe na-agbaze CPVC na igwe igwe na ebu, wee kwụsị igwe ahụ ka ọ dozie nsogbu.

4. Tupu etinyere resin n'ime mmepụta, a ga-ehichapụ ya ma mesoo ya na igbe 80 ℃ maka awa 2-4. Ọ bụrụ na ọ dị mkpa, a ga-esikwa ngwa ngwa agwakọta ngwa ngwa dị elu site na sieve 40 n'otu oge, wee tinye ya na hopper extruder maka mmepụta.

5. The HCl gas wepụtara n'oge ire ere nke CPVC gbazee na-emerụ ahụ ike mmadụ, na e kwesịrị ilebara anya na ventilashion na mmepụta ogbako.

6. The extrusion igwe gbọmgbọm, ịghasa, na a wụrụ awụ ihe na-eru site na ịkpụzi ebu eji CPVC resin ga-enweta mgbochi corrosion ọgwụgwọ ịgbatị ọrụ ndụ nke akụrụngwa akụkụ.

N'ime usoro mmepụta n'ezie, usoro ịkpụzi extrusion nke polyvinyl chloride chlorinated ka siri ike. N'ezie, ọ dị mkpa ịhọrọ ngwaahịa kwesịrị ekwesị mgbe ị na-eji ya na ọnọdụ ụfọdụ, na anyị kwesịrị iji nlezianya tụlee usoro onunu ogwu nke ngwaahịa ahụ iji mee ka ojiji dị irè karị.
