Ụkpụrụ 7 iji nwalee nguzogide ihu igwe nke mkpuchi ntụ ntụ

Enwere ụkpụrụ 7 iji nwalee nguzogide ihu igwe nke mkpuchi ntụ ntụ.

• Iguzogide ngwa agha
• Ịka nká na ịdịte aka UV (QUV)
• Nnukwu nnụnnụ mmiri
• Kesternich-ule
• Florida-ule
• Ihu igwe (okpomọkụ ihu igwe)
• Nguzogide Chemical

Iguzogide ngwa agha

Dị ka ọkọlọtọ ASTM C207 si dị. A ga-ebute ngwa ngwa kpọmkwem na mkpuchi ntụ ntụ n'oge awa 24 na 23 Celsius C yana iru mmiri 50%.

Ịka nká na ịdịte aka UV (QUV)

Nnwale a na QUV-weatherometer nwere okirikiri abụọ. A na-ekpughere paịlị testpanels mkpuchi mkpuchi 2h na ọkụ UV yana 8h na condensation. A na-emeghachi nke a n'oge 4h. Kwa awa 1000, a na-enyocha panel. N'ebe a, a na-anwale mkpuchi ahụ na agba na njigide gloss.

Nnwale ịgba nnu

Dị ka ụkpụrụ ISO 9227 ma ọ bụ DIN 50021 si dị. A na-etinye oghere ndị a na-ekpuchi ntụ ntụ (ya na cross Andreas na-akpụ akpụ n'etiti site na ihe nkiri ahụ) na ebe dị ọkụ na-ekpo ọkụ ma fesa ya na nnu. Nnwale a na-enyocha ogo nke nchebe site na mkpuchi na corrosion na gburugburu nnu (dịka n'akụkụ oke osimiri). Ọtụtụ mgbe, akpa ule a na-ewe 1000h, na-eme ndenye ego kwa awa 250 ọ bụla.

Kesternich-ule

Dị ka ụkpụrụ DIN 50018 ma ọ bụ ISO3231 si dị. Na-enye ihe ngosi dị mma maka nguzogide mkpuchi na gburugburu ụlọ ọrụ mmepụta ihe. Maka oge a kapịrị ọnụ, a na-etinye panel ule mkpuchi mkpuchi na gburugburu iru mmiri na-ekpo ọkụ, nke nwere sulfur dioxide. Nnwale a na-agba ọsọ 24h-cycle na njikwa kwa 250h.

Florida-ule

N'ime opekempe 1 afọ a na-ekpughere panel testpanels na gburugburu anwụ na-acha na iru mmiri nke Florida, USA. A na-enyocha gloss yana njigide agba.

Nnwale iru mmiri ( ihu igwe okpomọkụ)

Dị ka ụkpụrụ DIN 50017 ma ọ bụ ISO 6270. A na-egbu ya n'ime ụlọ nke nwere oke iru mmiri, na okpomọkụ siri ike na mgbe mgbe 1000h. Kwa awa 250, a na-eme njikwa njikwa na paịlị mkpuchi ntụ ntụ yana Andreas-cross jiri mma kpụrụ ya site na ihe nkiri dị n'etiti. Nnwale a na-enyocha ihe na-akpụ akpụ nke iru mmiri na corrosion na gburugburu iru mmiri.

Nguzogide Chemical

A na-anwale nguzogide kemịkalụ na mkpuchi a na-edozi, kọntaktị na ncha ma ọ bụ kemịkalụ. Edepụtaghị ọnọdụ ọkọlọtọ. Ya mere, onye na-emepụta ntụ ntụ na-edozi ọnọdụ ahụ na mkparịta ụka na onye na-eme ihe ma ọ bụ onye ahịa ikpeazụ.

Iji nwalee iguzogide ihu igwe nke mkpuchi ntụ ntụ dị ezigbo mkpa na ngwa mkpuchi ntụ ntụ.
