Kedu ihe dị iche n'etiti ọkpọkọ PE na ọkpọkọ HDPE?

Ihe dị iche n'etiti HDPE ọkpọkọ na ọkpọkọ PE bụ ajụjụ a na-ajụkarị. Ọ dị ka ọ dị mfe, mana mmadụ ole na ole na-akọwa ya nke ọma. N'ebe a, anyị ga-ewebata gị ya n'usoro.

Ọkụ PE bụ ọkpọkọ plastik polyethylene. Dị ka ndị kasị isi ụdị plastic, PE nwere ezigbo nguzogide nke ọtụtụ kemịkalụ ụlọ na ụlọ ọrụ mmepụta ihe. Akpa rọba nkịtị, ihe nkiri nri, wdg. ihe niile bụ nke PE.

Enwere ike kewaa ọkpọkọ PE n'ozuzu ya na ụdị atọ: obere njupụta polyethylene ọkpọkọ (LDPE ọkpọkọ), ọkpụkpụ polyethylene nke ọkara-njupụta (MDPE ọkpọkọ), na ọkpọkọ polyethylene dị elu (HDPE ọkpọkọ).

1. Obere njupụta polyethylene (akpọchiri dị ka LDPE)

Low-density polyethylene is generally produced by high-pressure polymerization with a density of 0.9910 -0.925g/cm ³. Ọdịdị molekụla nke polyethylene dị obere bụ macromolecule linear nwere ọtụtụ agbụ akụkụ.. Agbụ n'akụkụ nke ogologo dị iche iche na agbụ isi na-emetụta nhazi oge nke macromolecule, na stacking adịghị úkwù, nke na-egbochi kristal nke polyethylene. Ya mere, kristal bụ 55% -65%. Polyethylene dị ala nwere obere agbaze na ihe dị nro. Agbụ n'akụkụ ogologo na-enye ya obere viscosity na ọnụ ọgụgụ dị elu n'oge nhazi na ike mgbaze dị elu n'oge mgbatị, na-eme ka ọ dị mma maka usoro ihe nkiri a na-afụ ụfụ na-ejikarị eme ihe na mmepụta ihe nkiri ugbo, ihe nkiri nkwakọ ngwaahịa dị arọ, wdg.

2. Ọkara-njupụta polyethylene (MDPE maka nkenke)

Ọkara-njupụta polyethylene (MDPE) A na-achịkwa njupụta site na A-olefin copolymerization na ọkara na obere nrụgide site na iji ihe na-arụ ọrụ nke ọma.

(0.926-0.940q/cm3), na kristal nke 70%-80%. N'ihi ọtụtụ agbụ akụkụ ya dị ogologo, njupụta na crystallinity mbelata, polyethylene nke ọkara-njupụta nwere ngbanwe dị mma na njirimara okpomọkụ dị ala, na ike tensile ya, isi ike, Njirimara thermal, wdg. dị ala karịa ndị nke nnukwu njupụta polyethylene. N'ihi eziokwu ahụ bụ na copolyolefin nwere ike ịbawanye ụdọ njikọ intergranular nke akwụkwọ kristal nke ọkara-njupụta polyethylene., Nguzogide ya na mgbawa ngwa ngwa na njigide ogologo oge nke ike igwe na-akawanye mma ma e jiri ya tụnyere LDPE. Enwere ike iji polyethylene njupụta nke ọkara na mmepụta nke ọkpọkọ nrụgide, ọkpọkọ nnyefe, igbe dị iche iche na ihe nkiri nkwakọ ngwaahịa.

3. Polyethylene dị elu (HDPE maka mkpụmkpụ)

Polyethylene dị elu (HDPE) A na-emepụta ya site na usoro polymerization dị ala, bụ linear, nwere njupụta nke 0.94-0.965q/cm ³, nwere kristal nke 80%-95%, na bụ ntụ ntụ ọcha ma ọ bụ granule. Tụnyere ya na obere njupụta polyethylene, ọ nwere obere agbụ ndị ọzọ dị ntakịrị, ihe owuwu ahịrị dị nso, ụmụ irighiri ihe mgbe niile na nso nso, ma si otú ahụ nwere nnukwu crystallinity, nnukwu njupụta, Ọnụọgụ molekụla ndị ikwu sitere na narị puku kwuru puku ruo ọtụtụ narị puku, na warara nso nke gbazee eruba eruba. Nnukwu njupụta polyethylene nwere nnukwu siri ike na ike, ike igwe dị mma na nguzogide okpomọkụ, yana ezigbo iguzogide ihe omimi miri emi na ntinye uzuoku. Polyethylene dị elu nwere ikike kachasị dị ala n'etiti ụdị polyethylene niile, kasị ike corrosion eguzogide, na ezigbo isi ike, a na-ejikarị eme ihe na mmepụta nke ọkpọkọ nrụgide dị iche iche, ngwaahịa akpụ akpụ ntụtụ, wdg.

HDPE ọkpọkọ bụ ụdị ọkpọkọ PE, mana arụmọrụ nke ọkpọkọ HDPE dị elu karịa nke ọkpọkọ PE nkịtị, nke anyi nwere ike ichikota dika ndia:

1, Nguzogide nrụgide dị iche iche:

• Ọkụ HDPE ga-enwerịrị ike iguzogide ụfọdụ nrụgide, na-abụkarị ibu dị elu molekụla na ezigbo akụrụngwa akụrụngwa PE resin na-ahọrọ, dị ka HDPE resin, nke dị ike ugboro itoolu karịa ọkpọkọ polyethylene nkịtị (PE ọkpọkọ);

2, ihe mgbochi iyi dị iche

• N'ime plastik injinia niile, HDPE nwere nguzogide abrasion kacha mma. Nke dị elu nke molekụla arọ, ihe na-eyi na-eguzogide ihe, ọbụna karịa ọtụtụ ígwè ihe (dị ka carbon ígwè, igwe anaghị agba nchara, ọla kọpa, wdg.) nguzogide abrasion nke PE nkịtị bụ naanị otu ụzọ n'ụzọ iri nke HDPE;

3, Ojiji dị iche iche

• Ọkpụkpọ PE General (ọkpụkpụ polyethylene nke ọkara-njupụta) dị mma maka ibufe gas artificial gas, eke gas, mmanụ mmanụ gas, mgbe obere njupụta polyethylene ọkpọkọ na-agbanwe tubes;
• HDPE ọkpọkọ (ọkpọkọ polyethylene dị elu) a na-ejikarị ebufe gas, usoro nhazi mmiri nke ime obodo, usoro mmiri ime ụlọ nke ụlọ, Sistemụ mmiri e liri n'èzí na usoro inye mmiri e liri n'ebe obibi na ụlọ ọrụ mmepụta ihe, Nrụzi pipeline ochie, sistemu pipeline engineering mmiri ọgwụgwọ, na ọkpọkọ mmiri mmepụta ihe na ubi, ogbugba mmiri n'ubi na ubi ndị ọzọ.
• HDPE ọkpọkọ can be used as a replacement for traditional steel pipes and polyvinyl chloride drinking water pipes, nke ọkpọkọ PE nkịtị enweghị ike.

4，Ụzọ njikọ dị iche iche:

• Ọkpụkpọ PE General, especially LDPE and MDPE, are often connected using mechanical fittings or quick-connect joints, which are convenient for flexible tubing and low-pressure applications.
• HDPE ọkpọkọ, n'akụkụ aka nke ọzọ, are widely recognized for their compatibility with heat fusion technology. Butt fusion and electrofusion create a seamless joint that is as strong as the pipe itself, ensuring a completely leak-proof system for high-pressure water and gas transmission.

5，Cost and economic value:

While general PE materials are generally cheaper and widely used in packaging and low-stress environments, HDPE pipes offer a higher initial investment but deliver exceptional long-term value.,

Due to their superior durability, lower maintenance needs, and extended lifespan, HDPE pipes significantly reduce replacement and operational costs over decades of use, making them highly cost-effective for major infrastructure projects.
