Kedu ụdị rọba injinịa bụ?

October 26, 2024

Gịnị bụ na plastik injinịa? Ọ na-ezo aka na polyethylene teered (Petp) plastic. Plastic plastik bụ ihe na-ahụkarị na-ahụkarị, aha ndị China (polyester) nwere ihe ndị na-esonụ: n'ime nri na-ejikarị.

Plastic plastik bụ mkpọchi maka polyethylene terephthalate, ndebiri anụ ma ọ bụ Petp. Ihe ndị China pụtara: Polyyethylene Ifufhalate, nke tinyere polyethylene tere mmanụ na polybuutylene temphthalate Polt. A na-akpọkwa polyethylene teerephthalate dị ka resin resin. Ọ bụ condensate nke acid na ethylene glycol, yana PBT, ma ọ bụ na-ezo aka na polyester, ma ọ bụ na-ezo aka na polyester, ya mere, ọ nwere ogo dị elu nke Ngwongwo nke fim na n'ime ọdịdị nke anụ ụlọ nwere ezigbo ngwa ngwa na nguzogide na-eguzogide, plastik plastik nwere ezigbo echiche anya siri ike. Na mgbakwunye na plastik plastik nwere ezigbo ọgba aghara aghara aghara ma sie ike na mkpuchi eletrik.

A na-akpọ plastik injinịa nke ọtụtụ aha, dịka, ma bụrụ maka anụ ụlọ, anụ ụlọ / pep poyester, iji ghọta akụrụngwa plastik ya:

1. Ntughari na-eguzogide:

Enwere ike iji plastik plastik ruo ogologo oge na okpomọkụ nke 120 Celsius C, ka ha na-enwe ọmarịcha anụ ahụ na nke igwe na oke okpomọkụ. Obere oge nke 150 Celsius C.

2. Na akụrụngwa anụ ahụ:

Plastic plastik nwere mmiri dị ala, na-enweghị nsi, ezigbo ihu igwe na-eguzogide, ike ikuku dị elu, ma nwee ike iguzo acids na-esighi ike. Agbanyeghị, ọ naghị eguzogide ọgwụ na-ekpo ọkụ na alkali.

3. ỌMA: (ọdịdị)

Plastic plastik na-abụkarị mmiri na-acha ọcha ma ọ bụ ìhè edo edo na-acha uhie uhie na kristal polymen nwere oke na elu.

4. Njirimara eletriki:

Plastic plastik nwere oke elektrik, ọbụlagodi na oke okpomọkụ na ugboro dị elu, akụrụngwa eletriki dị mma, ọ bụ ezie na corona na-eguzogide ọgwụ na-enwe polymer nwere ezigbo polycer. Ya dielctric na-adịgide adịgide n'okpuru ọrụ nke ọkụ eletriki bụ oke igodo iji tụọ akụrụngwa eletriki ya. Dabere na nsonaazụ ahụ kwupụtara, na-enwe anụ ụlọ na-enwekarị ihe dị ka 2.5 na 3.5 na elu ugboro abụọ (ọkwa MHZ) na 4 na mpaghara ugboro 3 na 4 na ọkwa dị ala). Na mgbakwunye, peonectric na-enwekarị anụ ụlọ na-agbadata na ịba ụba.

5. Nhazi:

Plastik plastik nwere obere kristal na-egbu egbu, na-eme atụmatụ nhazi ha. A chọrọ ngwa ngwa iji nweta ngwaahịa ntụ (dịka fim) yana nke zuru oke ihicha tupu ịkpụzi.

Akụrụngwa ihe nwere ezigbo nguzosi ike ma na-adịchaghị ntanye na mmezi n'ihi mgbanwe gburugburu ebe obibi.

7. Echiche dị elu:

Ihe nwere nghọta nwere nghọta dị mma, nke na-eme ka ọ dị mma maka iji ya mepụta nkwakọ ngwaahịa na akpa chọrọ mmetụta dị mma.

8. Ntughari:

Pet bụ ihe ntụgharị nke enwere ike ịmegharị ma na-emegharị iji belata mmetọ gburugburu ebe obibi.

Pet nwere ike ịnọgide na-eme ihe ụfọdụ eji arụ ọrụ ọbụlagodi na obere okpomọkụ, adabara iji na friji ma ọ bụ na-ajụ oyi.

10. Echiche:

Elu ahụ nwere ezigbo gloss, nke nwere ike inye ọdịdị mma.

11. Mmiri Andporption:

Ihe na-enye aka hygroscopity, nke na-enyere aka mee ka ngwaahịa akọrọ ma sie ike.

Ejiri karama nke nwere nnukwu karama, nghọta dị mma, na-enweghị ihe na-egbu egbu, na-ejikwa ya, na-arụ ọrụ na-emepụta ihe dị ka, ọtụtụ ihe na-ewetakwa , naanị isi ihe nke irighiri ihe site na metylone abụọ ka ọ dị anọ, yabụ na molekule dị mma, ịrụ ọrụ dị mma karịa.

Petp bụ milky na-acha ọcha ma ọ bụ ìhè edo edo na kristal kristal na-acha uhie uhie ma na-acha uhie uhie. Na-eguzogide, ike ọgwụgwụ na-eguzogide na nkwụsi ike na nguzosi ike, obere ihe siri ike ma sie ike na thermoplastics; Ezigbo ihe mkpuchi mkpuchi mkpuchi eletrik, nke na-emetụta okpomọkụ, mana coronanceda Coronanced. Na-abụghị ihe na-egbu egbu, nguzogide ihu igwe, nnabata dị mma, na-eguzogide acid acid na soonic na-adịghị mma, ma ọ bụghị iguzogide imikpu mmiri na-ekpo ọkụ.
