Taa, m ga-enye gị nkọwa dị nkenke banyere akụkọ ihe mere eme nke plastik.

Plastic mbụ zuru oke na akụkọ ihe mere eme mmadụ bụ resin phenolic nke American Baekeland mere na phenol na formaldehyde na 1909, nke a makwaara dị ka plastik Baekeland.A na-eme resin phenolic site na mmeghachi omume condensation nke phenols na aldehydes, ma bụrụ nke plastik na-ekpo ọkụ.A na-ekewa usoro nkwadebe ahụ n'ime ụzọ abụọ: nzọụkwụ mbụ: mbụ polymerize n'ime ogige nke nwere akara dị ala nke polymerization;Nzọụkwụ nke abụọ: jiri ọgwụgwọ okpomọkụ dị elu mee ihe iji gbanwee ya ka ọ bụrụ ngwakọta polymer nke nwere nnukwu ogo polymerization.
Mgbe ihe karịrị otu narị afọ nke mmepe, ngwaahịa plastik dị ugbu a n'ebe nile ma nọgide na-eto eto na ọnụ ọgụgụ dị egwu.Resin dị ọcha nwere ike ịbụ enweghị agba na nghọta ma ọ bụ na-acha ọcha n'ọdịdị, nke mere na ngwaahịa ahụ enweghị atụmatụ doro anya ma mara mma.Ya mere, inye ngwaahịa plastik na agba na-egbuke egbuke aghọwo ọrụ a na-apụghị izere ezere nke ụlọ ọrụ nhazi plastik.Gịnị mere plastik ji mepụta ngwa ngwa n'ime naanị otu narị afọ?Isi n'ihi na o nwere uru ndị a:

1. Enwere ike imepụta plastik n'ọtụtụ buru ibu. (Siteplastic ebu)

2. Njupụta dị nfe nke plastik bụ ìhè na ike dị elu.

3. Plastic nwere nguzogide corrosion.

4. Plastic nwere ezigbo mkpuchi na ihe mkpuchi okpomọkụ.

Enwere ọtụtụ ụdị plastik.Kedu ihe bụ isi ụdị thermoplastics?

1. Polyvinyl chloride (PVC) bụ otu n'ime ndị isi n'ozuzu-ebumnobi rọba.N'ime rọba ise kachasị elu n'ụwa, ikike imepụta ya bụ nke abụọ karịa polyethylene.PVC nwere ezigbo isi ike na nguzogide corrosion, mana enweghị ngbanwe, na monomer ya na-egbu egbu.

2. Polyolefin (PO), ndị a na-ahụkarị bụ polyethylene (PE) na polypropylene (PP).N'ime ha, PE bụ otu n'ime ngwaahịa rọba kacha ibu n'ozuzu.PP nwere njupụta dị ala, ọ dịghị egbu egbu, enweghị isi ma nwee ezigbo nguzogide okpomọkụ.Enwere ike iji ya ogologo oge na okpomọkụ nke ihe dịka 110 degrees Celsius.Anyịngaji plastikbụ nke nri ọkwa PP.

3. Styrene resins, gụnyere polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS) na polymethyl methacrylate (PMMA).

4. Polyamide, polycarbonate, polyethylene terephthalate, polyoxymethylene (POM).Enwere ike iji ụdị plastik a dị ka ihe eji arụ ọrụ, nke a makwaara dị ka ihe injinia.

Edewo nchọpụta na iji plastik mee ihe n'akụkọ ihe mere eme, ọ bụkwa ihe nke abụọ dị mkpa e mepụtara nke metụtara ihe a kpọrọ mmadụ na narị afọ nke 20.Plastic n'ezie bụ ọrụ ebube n'ụwa!Taa, anyị nwere ike ikwu na-enweghị ikwubiga okwu ókè: "A pụghị ikewapụ ndụ anyị na plastik"!
