Nke a polyethylene na iko iko jikọtara ọnụ, dị elu, ezigbo okpomọkụ, bụ ụdị plastik injinịa. Enwere ike hazie ya site na mkpagbu, apụpụ, na-akpụ akpụ, wdg na-eji ya, akụkụ ọkpọkọ, akụkụ ihe omume), na ụlọ Akụkụ elektrik, wdg 5. 5.

5. Wolyethylene wax

Po polyethylene dị ala polyethylene nwere nnukwu molecular nke 1000 ~ 10000 polyethylene wax. N'afọ ndị na-adịbeghị anya, ụlọ ọrụ Mitsui Petroical ejirila ụdị Zieglers mepụta nke ọma iji mepụta oke, onye na-ajụ oyi polyethylene wax. A na-eji ezigbo kemịkalụ na ikuku kwụsie ike, dị nro dị elu dị ka 114 ~ 132'C, njikọ dị ezigbo mma, agba dị mma, na-acha ọcha na adịghị emerụ ahụ. A na-eji ụdị ọkwa dị elu dị ka DRE ịchụsapụ, roba na ịdekọ ọnụ na-agwakọta, mkpuchi, mbipụta na ntinye akwụkwọ na ntinye akwụkwọ; A na-eji ụdị ọkwa dị ala na-ejikarị dị ka ihe mgbakwunye iji melite arụmọrụ nke plastics.

6. chlorinated polyethylene

Ọkụ chlorinated (CPE) bụ ihe na-acha ọcha na-acha ọcha, ọ bụghị ihe na-atọ ụtọ, na-eguzogide na-enweghị isi, na-eguzogide na-eguzogide na-arụgide ya, na-eguzogide na ngwa agha. Ezigbo nsogbu (ka na-agbanwe agbanwe na -30 ℃), ezigbo ndakọrịta na ihe polymer ndị ọzọ, oke okpomọkụ, ihe dị elu nke hcl, na-emebi ihe dị elu nke CPE.

Chlorinated polyethylene bụ chloride chloride enwetara site na dochie ụfọdụ amydylene na chlorine nke ethylene, vinyl chloride, na dichlororethylene. Mwepụta nke chlorine amịrị na polyethylene molerene na-ebelata kristal, na-ebelata okpomọkụ ma na-abawanye mgbanwe.

Dabere na ogo molecular na nkesa nke polyethylene, ogo nke clorrination, a ga-enweta polyethylene polyethylene site na rọba siri ike. Pollally na-abụghị kristal ma ọ bụ obere kristal polyethylene bụ Ruby. Ọ bụrụ n 'mkpu a na-abawanye, ọ na-aghọ amorphous resin na ụba na ụba na ịdị elu dị elu ma dị nro. Na mgbakwunye na usoro ihe mgbaze (chloroberndone, carbon Tetrachloride, wdg dị ka ihe mgbazinye) maka ogige na-ejikarị, usoro nkwụsị nke a na-ejikarị na ụlọ ọrụ. Dabere na ọnọdụ mmeghachi omume, a na-ekewa ya iji gbochie chlorination (obere okpomọkụ) na chlornation chlorination (okpomọkụ karịa isi ihe na-agbaze). Na-abụghị kristal iji obere obere ihe na-acha ọbara ọbara na-emepụta site na chlorination na-enweghị atụ.

Ọkpụkpụ ndị na-esochi ndị na-esochi ya: ezigbo ọnọdụ dị mma, ezigbo usoro, nke abụọ na-eme ihe na-achagharị na-achagharị na kemịkal nke kemịkal (ọ dịghị mfe ọkụ chlorine ọdịnaya nke ihe kariri 25%), ezigbo ihu igwe na-eguzogide, nguzozi ozone na nchekwube iguzogide.

Enwere ike ịkpụ polyethylene chlorine nke na-abụghị nke polyethylene naanị, yana akụrụngwa yiri nke chlorosulfontonated polyethylene, ma enwere ike iji ya na mpempe akwụkwọ ndị ọzọ. Enwere ike iji chlorinated polyethyletene na fillenlen, fọdụrụ ma na-ekwu okwu (iji gbochie nrụnye nke hydrogen chloride site na ikpo ọkụ. Mgbe agwakọtara ya na PVC, enwere ike ịmepụta plastik PVC iji melite nsonaazụ nrụgide, nguzogide ọnọdụ dị ala na nhazi ọnọdụ. A na-ejikwa ya dị ka plastizer na-adịgide adịgide, mkpuchi na nrapado. Chlorinated polyethylene bụ obere ọnụ karịa oke chloroprene roba na chlorosulfored polyethylene.

7. Chlorosulfonated polyethylene

Chlorosulfontonated polyethylene (CSM) bụ mbu ụlọ ọrụ na-arụ ọrụ na 1952. Chlorosulforene na-emepụta polyethylene ma ọ bụ na-enwe oke polyethylene site na chlorosilition. Ọ bụ elastomer ọcha ma ọ bụ odo, soluble na aromatic hydrocarbons na hydrocarbons hydrocarbont, innoluble na abụba na nke a na-a ofụ.

CSM bụ elastomer nke nwere polyethylene dị ka isi yinye, nkezi molecular arọ 30,000 ~ 120,000. Chlorosulfored polyethylene bụ ihe ọcha na-acha ọcha ma ọ bụ milk na-acha ọcha. Ihe owuwe ihe nkiri CSM ji jupụta, yana ezigbo ozone guzogide, ihu igwe, iguzogide, iguzogide, mmiri na-eguzogide, na nguzogide mmiri. CSM nwere oke iguzogide ya, iguzogide ihu igwe, iguzogide elu, iguzogide ya, wdg. Hydrocarbons, na Bụ naanị soruble na ketone, Ester, e nwere, na innoliteble na alipatic hydrocarbons na mmanya.

Mgbe polyethylene na chlorine nwere sọlfọ dioxide, akụkụ nke tydrogen na-eji chlorine dochie ya, -oicl), a na-akpọ ngwaahịa a chlorosulfofodforeted polyethylene. Ọ bụ nke Ruby, n'ihi na ọ nweghị nkekọ okpukpu abụọ, yabụ ọ na-eguzogide ọgwụ, ma nwee ezigbo mmiri, ma nwee ogologo oge n'okpuru 120 ℃), ezigbo tensile Ike, modulus na isi ike dị elu, na-eguzogide na-eguzogide, na ọbụna anaghị eji rọba na 50 ℃ nke obere okpomọkụ adịghị emegharị, na iguzogide mwepu corrona.

CSM n'ihi na usoro molecular nwere Chlorosulfonyl otu, yabụ, ọ na-egosiputa ihe omume dị elu, ọkachasị Njirimara Omone, kamakwa iguzogide radieshon nke Ionic, iguzogide ala di ala, iguzogide ngbanwe na mkpuchi eletrik na njiri mara mma. Emechaala CMM nke ukwuu maka ebumnuche ndị agha injinịa. Ma nrụrụ ya na-adịgide adịgide na-emekwa ka ọ dị.
