Kedu uru dị n'iji polyethylene a kpụchara akpụcha (CPE) mee ihe n'ime ihe ndị mejupụtara plastik osisi PVC?

1, Mee ka ike na mmetụta siri ike dịkwuo mma
Ime ka ike sie ike dịkwuo elu: CPE, dịka elastomer, na-eme ka ike nke PVC matrix dịkwuo mma site na ngwakọta anụ ahụ, na-eme ka ike mmetụta nke ihe mejupụtara ya dịkwuo elu nke ukwuu. Nnwale egosila na itinye akụkụ iri nke CPE nwere ike ime ka ike mmetụta nke ihe mejupụtara plastik osisi PVC a fụfụ dịkwuo elu site na 20%. Bontecn Group CPE pụrụ iche nke plastik osisi China nwere ike ime ka ike ngwaahịa dịkwuo mma nke ukwuu ma belata ọnụ ahịa mmepụta. Nnọọ ka ị jụọ ajụjụ.
Nhazi arụmọrụ okpomọkụ dị ala: Ihe nkwado molekul agbụ ígwè na-agbanwe agbanwe nke CPE na-eme ka mgbanwe ya dịkwuo mma na gburugburu okpomọkụ dị ala, na-ezere mmebi okpomọkụ dị ala.
2, Meziwanye arụmọrụ nhazi na ndakọrịta
Njikọ njikọ emelitere: Eriri osisi (dịka cellulose) nwere ọtụtụ otu hydroxyl ma ha enweghị ike ikwekọ na PVC hydrophobic. Atọm chlorine polar na nhazi nkewa nke CPE na-arụ ọrụ dị ka "akwa" iji melite njikọta dị n'etiti eriri na PVC, na-ebelata nkewa nke usoro.
Mee ka mmiri gbazee ka mma: CPE na-ebelata mmiri gbazee, na-ebelata mmebi nke mmiri nhazi nke oke ntụ osisi na-ejupụta, ma na-eme ka ngwakọta na mkpụcha ihe dị nro.
Ọmụmụ ihe gbasara ọrịa na-egosi na CPE 5 phr nwere ike ịkwalite mmepụta gel PVC ma mee ka viscosity dị mgbagwoju anya nke agbaze ahụ dịkwuo elu; Na akụkụ iri, a na-ebelata viscosity iji mee ka arụmọrụ nhazi na arụmọrụ dịkwuo mma.
3, Mmelite atụmatụ ọrụ
Mmezi nke ire ọkụ: Ka ọdịnaya chlorine dị na CPE dị elu (ọkacha mma 36-38%), otú ahụ ka mmetụta retardant ọkụ si dị ukwuu. Atọm chlorine ya na-ewepụta hydrogen chloride n'oge ọkụ iji gbochie mgbasa nke ire ọkụ.
Nguzogide na Ịkwụsi Ike n'Ihu Igwe: Usoro molekul juru eju nke CPE na-enye ihe ndị mejupụtara ya ikike ịka nká nke ọma, iguzogide ozone, na iguzogide nchara kemịkalụ, na-agbatị ndụ ọrụ ha n'èzí.
4, Njikwa zuru oke nke ihe onwunwe igwe
Nha nhata ike na nkwụsi ike: Ọnụọgụ CPE kwesịrị ekwesị (akụkụ 5-15) nwere ike ime ka ike sie ike ka mma ma na-ejigide ike nrụgide, nkwụsi ike, na iguzogide ihe na-asọ asọ. Mgbakwunye gabigara ókè nwere ike ibute mbelata ike, nke a ga-achịkwa site na nhazi usoro.
5, Nchịkọta
CPE na-edozi nsogbu nke nnukwu mmebi, nhazi siri ike, na ire ọkụ na ngwakọta plastik osisi PVC site na usoro okpukpu anọ nke ike, ndakọrịta njikọ, ihe enyemaka nhazi, na nkwalite ọrụ, na-aghọ ihe mgbanwe isi maka mmepe arụmọrụ ha dị elu. Ịhọrọ CPE nke nwere ọdịnaya chlorine nke 35-38% na ime ka ọnụọgụ mgbakwunye dịkwuo mma (na-abụkarị akụkụ 5-15) nwere ike nweta nguzozi n'etiti arụmọrụ na ọnụ ahịa.
