Ihe ndị na-emetụta arụmọrụ nke polyethylene a chlorine (CPE):

1. Ọdịnaya chlorine
Mmekọrịta dị n'etiti oke na arụmọrụ: Ọdịnaya chlorine nke CPE na-abụkarị 25% -45%. Mgbe ọdịnaya chlorine dị ≥ 35%, ọ nwere ihe ndị na-eme ka ọ gbanyụọ onwe ya (LOI ≥ 28%), mgbe ọ gafere 40%, a na-eme ka ike ire ọkụ ka mma nke ukwuu.
Arụmọrụ okpomọkụ dị ala: Mgbe ọdịnaya chlorine dị 30% -40%, ihe ahụ ka na-anọgide na-agbanwe agbanwe na -30 ℃.
2. Usoro chlorine
Nkesa atọm chlorine: CPE nke e ji usoro ngwọta, usoro nkwụsịtụ ma ọ bụ usoro sulfurization kwadebe, otu nkesa atọm chlorine na-emetụta ndakọrịta ya na ihe onwunwe ya.
Nhazi obere ihe: Ogo nke chlorine na-emetụta okpomọkụ mgbanwe iko (Tg) nke CPE, a kwesịkwara inyocha arụmọrụ obere okpomọkụ site na nyocha thermomechanical na-agbanwe agbanwe.
3. Mgbanwe ngwakọta
Ime ka PVC sie ike: Ijikọta CPE na PVC (agbakwunyere akụkụ 5-15) nwere ike ime ka ike mmetụta dịkwuo elu ugboro 3-5 ma mee ka iguzogide ihu igwe ka mma.
Njikọta ihe na-egbochi ire ọkụ: Ngwakọta ya na magnesium hydroxide (Mg (OH) ₂) nwere ike ibelata njupụta anwụrụ ọkụ ma melite nkwụsi ike okpomọkụ.
4. Sistemụ sọlfọ
Njupụta njikọta: Peroxides (dịka DCP) ma ọ bụ ihe ndị na-eme ka ihe dị n'ime thiourea nwee ike ime ka usoro njikọ njikọta nke CPE ka mma, melite iguzogide mmanụ na ike igwe.
5. Ijuputa na nhazi
Ihe ndị na-eme ka ihe ghara ịdị n'ime: Ịtinye carbon black ma ọ bụ titanium dioxide nwere ike ịgbanwe àgwà nke ihe na-eme ka ihe dị n'ime ya na agba, mana oke njupụta nwere ike ibelata ike ịrụ ọrụ.
Okpomọkụ nhazi: Okpomọkụ ire ere nke CPE dị elu, mana a ga-ezere oke okpomọkụ ka ọ ghara ibute mmeghachi omume dechlorination nke HCl.
6. Mgbanwe ngwa
Rọba pụrụ iche: CPE nwere ọdịnaya chlorine nke 25% -35% dị mma maka ọnọdụ ndị na-egbochi ire ọkụ dịka mkpuchi eriri.
Mgbanwe ABS: CPE ụdị C na AZ nke Bontecn Group China mepụtara nwere ike ime ka ABS ghara ire ọkụ ma gbochie ntapu, belata ọnụọgụ ihe ndị na-egbochi ire ọkụ ejiri.
