Gwa gị gbasara ihe ndị bụ isi na ojiji nke polypropylene (PP).
Nke mbụ, gịnị bụ polypropylene?A na-akpọchi polypropylene dị ka "PP".Ọ bụ resin thermoplastic nwere nhazi oge niile na eluELECTIC THERMAL ACTUATOR(cystallinity dị elu dị ka 95%) polymerized sitere na propylene.Ọ nwere ike kewaa PP injection ịkpụzi, PP waya ịbịaru, PP eriri, PP film, PP ọkpọkọ.N'ime plastik ndị a na-ejikarị eme ihe na ndụ, polypropylene bụ otu n'ime ụdị dị mfe.
N'okpuru bụ njirimara nke polypropylene:
1. Ngwongwo anụ ahụ: ndị na-adịghị egbu egbu, ndị na-esi ísì ụtọ, enweghị ụtọ, mmiri ara ehi na-acha ọcha na nnukwu njupụta crystalline naanị 0.9-0.91g / cm3, nkwụsi ike dị mma na mmiri.
2. Thermal arụmọrụ: Ọ nwere ezigbo okpomọkụ na-eguzogide, na ngwaahịa ya nwere ike igba ogwu na okpomọkụ n'elu 100 Celsius C, na agaghị deform na 150 Celsius C na-enweghị mpụga ike.Okpomọkụ na-ekpo ọkụ bụ -35 Celsius C, na embrittlement na-apụta n'okpuru -35 Celsius, na nguzogide oyi adịghị mma dị ka polyethylene.
3. Nkwụsi ike nke kemịkalụ: Nkwụsi ike nke kemịkal dị ezigbo mma.Na mgbakwunye na ịbụ nke sulfuric acid gbadoro anya na nitric acid gbakọtara, ọ kwụsiri ike na reagents kemịkalụ ndị ọzọ, mana aliphatic hydrocarbons dị ala, aromatic hydrocarbons na chlorinated hydrocarbons nwere ike ime ka polymer Propylene dị nro ma zaa, na nkwụsi ike kemịkalụ ya na-abawanye. mmụba nke crystallinity, ya mere, polypropylene kwesịrị ekwesị maka ịmepụta ọkpọkọ kemịkalụ dị iche iche na ntinye, ma nwee mmetụta dị mma na-egbochi corrosion.
4. Ngwa eletriki: O nwere ọnụọgụ dielectric dị elu, yana mmụba nke okpomọkụ, enwere ike iji ya mee ihe mkpuchi ọkụ eletrik na-ekpo ọkụ.Ọ na-enwekwa voltaji na-agbaji dị elu ma dị mma maka iji ya dị ka ngwa eletriki, wdg. Ọ nwere ezigbo nguzogide voltaji na arc, ma ọ nwere ọkụ eletrik dị elu, ọ dịkwa mfe ime agadi mgbe ọ na-ejikọta ya na ọla kọpa.
A na-ejikarị polypropylene eme ihe na ngwa ụlọ na ọkpọkọ plastik.Ngwa ụlọ etolitela ngwa ngwa n'afọ ndị na-adịbeghị anya, nwere ọtụtụ ụdị na nnukwu mmepụta.Ya mere, n'ime afọ ole na ole sochirinụ, a ga-abawanye mmepe nke PP ihe pụrụ iche maka ngwa ụlọ iji gboo mkpa mgbanwe nke ahịa.
N'afọ 2003, ngụkọta mba nke ọkpọkọ rọba gafere karịrị nde tọn 1.8, mmụba kwa afọ nke 23%.N'oge mbụ, a na-ejikarị ọkpọkọ PP mee ihe dị ka ọkpọkọ mmiri ugbo, ma ahịa ahụ emeghị ka ọ mepee n'ihi nsogbu ụfọdụ na arụmọrụ nke ngwaahịa mbụ (ike mmetụta na nkwụsị nke ịka nká).Ma site na iwebata teknụzụ, a na-amata ahịa nke nta nke nta.Ọkpụkpụ rọba bụ otu n'ime ngwaahịa ndị bụ isi maka nkwalite na itinye ihe eji arụ ụlọ kemịkalụ na mba m.The Ministry of Construction nyere a "Ọkwa na-ike na Production Management na Nkwalite na Ngwa nke Copolymerized Polypropylene (PP-R, PP-B) Pipes" na 2001, na-achọ mkpa ngalaba Na-arụkọ ọrụ ọnụ na-eme ezi ọrụ si akụrụngwa, nhazi, ịdị mma iji ọkpọkọ na nrụnye, ma na-achịkwa ike nke ọkpọkọ PP, ka ọ wee rụọ ọrụ dị mma na mmepụta, ngwa na nkwalite nke ọkpọkọ PP na mba m.
Site na mmụba nke ụkpụrụ ndụ mmadụ, ọ bụ ezigbo mmepe mmepe iji mepụta ihe pụrụ iche PP transperent, ọkachasị ihe pụrụ iche PP nwere nghọta dị elu, mmiri dị mma, na imepụta ngwa ngwa chọrọ iji chepụta na hazie ngwaahịa PP kacha amasị ndị mmadụ.PP transperent bụ njirimara karịa PP nkịtị, PVC, PET, PS, ma nwee ọtụtụ uru na atụmanya mmepe.Ka ọ dị ugbu a, enwere nnukwu ọdịiche dị n'etiti ihe ndị pụrụ iche PP na-ahụ maka ụlọ na mba ndị ọzọ, na mmepụta na ntinye nke resin PP transperent na ngwaahịa ya ka kwesịrị iwusi ike.
Na mgbakwunye, a na-ejikwa polypropylene na-agbatị ihe nkiri PP na ihe ndị ọzọ.
