Nchara elu nke Sanwichi panel, kedu ihe nhọrọ?
2025-01-03
A maara PIR (polyisocyanurate) na PUR (polyurethane) Sanwichi panel maka arụmọrụ ha na mkpuchi mkpuchi na ọkụ ọkụ, ya mere a na-ahọrọkarị maka ọrụ dị ka nchekwa oyi. Isi ụfụfụ na-arụ ọrụ dị mkpa na mkpuchi mkpuchi na ọrụ nkwụsị ọkụ. Ma ị maara na nhọrọ nke ihe dị n'elu dịkwa mkpa ma nwee ike itinyekwu ọrụ na panels Sanwichi.
Otu n'ime ihe kachasị ewu ewu n'elu bụ PPGI: PPGI, ma ọ bụ Iron Galvanized Preprinted, bụ ihe ọla na-agbanwe agbanwe nke a na-ejikarị na-ewu na n'ichepụta. Ọ na-egosipụta ntọala nchara galvanized nke ejiri akwa akwa kpuchie maka nguzogide corrosion dị mma na ịdịte aka. Ihe ndị dị mkpa gụnyere ọdịdị ya dị fechaa yana ịdị ya n'ụdị agba dị iche iche yana mechaa maka nhazi ihe ịchọ mma. PPGI dịkwa mma na gburugburu ebe obibi dịka usoro mmepụta ya na-emepụta obere ihe mkpofu. PPGI nwere ogologo ndụ ọrụ yana obere ihe ndozi chọrọ, na-eme ka ọ dị mma maka mkpuchi ụlọ, mgbidi mgbidi na ngwa ndị ọzọ.
Ọtụtụ mgbe, elu igwe PPGI nwere ike ịgbakwunye nguzogide corrosion, ike na ihe mgbochi mmiri na panel Sanwichi PIR na PUR Sanwichi na ojiji nchekwa oyi. Na otutu na agba agba, ha nwekwara ọdịdị mara mma.
Ihe ọzọ na-ewu ewu n'elu igwe bụ igwe anaghị agba nchara, igwe anaghị agba nchara na-arụ ọrụ nke ọma na ike, na SUS304 igwe anaghị agba nchara dị mma na nguzogide corrosion. Ọzọkwa, igwe anaghị agba nchara nwere ọdịdị na-egbuke egbuke pụrụ iche na-eme ka panel Sanwichi dị elu.
E wezụga na, ndị ọzọ n'elu ihe dị ka ahaziri alloy, aluminum na-ahọrọ maka pụrụ iche ojiji, dị ka nri mma ma ọ bụ ibu elu corrosion iguzogide.
E wezụga ihe nchara n'onwe ya, mkpuchi ahụ nwekwara ike inye aka na njirimara pụrụ iche.
Ihe mkpuchi a na-ahụkarị gụnyere:
1. PVDF (Polyvinylidene Fluoride): Amara maka nguzogide ya pụrụiche megide radieshon UV, kemịkalụ, na ihu igwe, PVDF na-enye mmecha na-egbuke egbuke nke na-ejigide ịdị mma agba n'oge. Nke a na-eme ka ọ dị mma maka ngwa dị n'èzí, karịsịa na ọrụ ụlọ.
2. HDP (Elu-Durability Polyester): Ihe mkpuchi HDP na-enye ike dị elu na nkwụsi ike, na-eme ka ha dị mma maka mpaghara okporo ụzọ dị elu na gburugburu ụlọ ọrụ mmepụta ihe. Ha na-echebe megide corrosion na gburugburu ebe obibi, na-agbatị ndụ nke ihe onwunwe.
1.EP (Epoxy Polyester): Ihe mkpuchi a na-ejikọta uru nke epoxy na polyester, na-enye ezigbo adhesion na iguzogide kemịkalụ na mmiri. Ihe mkpuchi EP dị mma maka ngwa ime ụlọ na gburugburu ebe mkpuchi kemịkalụ bụ nchegbu.
Mkpebi, ihe dị iche iche chọrọ nwere ike imeju site na ihe dị iche iche sanwichi panel maka ma PIR na PUR Sanwichi panel. Biko kpọtụrụ anyị na mkpa pụrụ iche nke ajụjụ, anyị ga-enyere gị aka ịchọta ngwọta kachasị mma maka nchekwa nchekwa oyi gị.
