Matrix resin nke ihe mejupụtara thermoplastic gụnyere plastik injinia izugbe na nke pụrụ iche, PPS bụkwa ihe nnọchianya nke plastik injinia pụrụ iche, nke a na-akpọkarị "ọlaedo plastik". Uru arụmọrụ gụnyere akụkụ ndị a: ezigbo iguzogide okpomọkụ, ezigbo njirimara igwe, iguzogide nchara, na ire ọkụ onwe onye ruo ọkwa UL94 V-0. N'ihi na PPS nwere uru arụmọrụ ndị a dị n'elu, ma e jiri ya tụnyere plastik injinia thermoplastic ndị ọzọ nwere arụmọrụ dị elu, ọ nwere njirimara nke nhazi dị mfe na ọnụ ala dị ala, yabụ ọ ghọọla matriks resin magburu onwe ya maka imepụta ihe mejupụtara.

Ihe mejupụtara PPS tinyere eriri iko dị mkpụmkpụ (SGF) nwere uru dị na ike dị elu, iguzogide okpomọkụ dị elu, ihe na-egbochi ire ọkụ, nhazi dị mfe, ọnụ ala dị ala, wdg.
Ihe mejupụtara eriri iko ogologo oge nke PPS (LGF) nwere uru dị ka ike siri ike, obere agha, ike ọgwụgwụ, ọdịdị ngwaahịa dị mma, wdg. Enwere ike iji ya maka impellers, casings mgbapụta, nkwonkwo, valvụ, impellers kemịkalụ na casings, impellers mmiri oyi na Shells, akụkụ ngwa ụlọ, wdg.

Ya mere, kedu ihe dị iche na njirimara nke eriri iko dị mkpụmkpụ (SGF) na eriri iko ogologo (LGF) nke ejiri PPS mee ka ọ sie ike?

A tụnyere ihe ndị mejupụtara PPS/SGF (mkpụmkpụ iko dị mkpụmkpụ) na ihe mejupụtara PPS/LGF (mkpụmkpụ iko ogologo). Ihe kpatara eji eji usoro ịgbaze agbaze eme ihe n'ịkwadebe ihe nhazi skru bụ na a na-ahụ na a na-etinye ihe mejupụtara eriri ahụ n'ime ebu a na-etinye, eriri ahụ adịghịkwa emebi emebi. N'ikpeazụ, site na ntụnyere data nke ihe owuwu nke abụọ ahụ, ọ nwere ike inye nkwado teknụzụ maka ndị ọrụ sayensị na teknụzụ na-eji ngwa mgbe ha na-ahọrọ ihe.

Nyocha ihe onwunwe igwe
Eriri ndị na-eme ka ihe sie ike agbakwunyere na matrix resin nwere ike ịmepụta ọkpụkpụ na-akwado ya. Mgbe ihe mejupụtara ya dị n'okpuru ike mpụga, eriri ndị na-eme ka ihe sie ike nwere ike ibu ọrụ nke ibu mpụga nke ọma; n'otu oge ahụ, ọ nwere ike ịmịkọrọ ike site na mgbawa, mgbanwe, wdg, ma melite njirimara igwe nke resin ahụ.

Mgbe eriri iko ahụ na-abawanye, ọtụtụ eriri iko dị na ihe mejupụtara ya na-enweta ike mpụga. N'otu oge ahụ, n'ihi mmụba nke ọnụọgụ eriri iko, matrix resin dị n'etiti eriri iko ahụ na-adị gịrịgịrị, nke na-enyere aka iwuli okpokolo agba nke eriri iko ahụ; ya mere, mmụba nke eriri iko ahụ na-eme ka ihe mejupụtara ya nwee ike ibufe nrụgide karịa site na resin gaa na eriri iko ahụ n'okpuru ibu mpụga, nke na-eme ka njirimara nrụgide na mgbagọ nke ihe mejupụtara ahụ dịkwuo mma.
Njirimara nrụgide na mgbanwe nke ngwakọta PPS/LGF dị elu karịa nke ngwakọta PPS/SGF. Mgbe oke eriri iko dị pasent 30, ike nrụgide nke ngwakọta PPS/SGF na PPS/LGF bụ 110MPa na 122MPa, n'otu n'otu; Ike mgbanwe bụ 175MPa na 208MPa, n'otu n'otu; modulu elastic flexural bụ 8GPa na 9GPa, n'otu n'otu.
Ike nrụgide, ike mgbanwe na modulus elastic nke ngwakọta PPS/LGF mụbara site na 11.0%, 18.9% na 11.3%, n'otu n'otu, ma e jiri ya tụnyere ngwakọta PPS/SGF. Ogologo njigide nke eriri iko na ihe mejupụtara PPS/LGF dị elu. N'okpuru otu ọdịnaya eriri iko ahụ, ihe mejupụtara nwere ike iguzogide ibu na njirimara igwe ka mma.
