Ngwọta maka nsogbu nke mkpuchi ntụ ntụ n'elu galvanizing na-ekpo ọkụ

1. Ọgwụgwọ ezughị ezu:

• polyester ntụ ntụ mkpuchi ntụ ntụ bụ thermosetting resins nke na-agafe n'ụdị organic ikpeazụ ha site na idobe ya na okpomọkụ (nke 180 o C), maka ihe dịka nkeji iri. Emebere oven nke na-agwọ ọrịa iji nye oge a na ngwakọta okpomọkụ. Na ihe na-ekpo ọkụ na-ekpo ọkụ galvanized, na akụkụ ha dị arọ karị, ọ dị mkpa iji hụ na a na-ahapụ oge ikpo ọkụ zuru ezu iji zute nkọwa ọgwụgwọ. Ịkpọ ọkụ tupu ọrụ dị arọ ga-enyere aka mee ka usoro ọgwụgwọ ahụ dịkwuo elu na oven ọgwụgwọ.

2. Adhesion na-adịghị mma:

• Oge ikpeazụ na usoro ịgbanye ọkụ na-ekpo ọkụ na-agụnye imenyụ mmiri nke ọrụ ahụ, na-emekarị na ngwọta sodium dichromate na-adịghị ike. Usoro a na-eme ka ọrụ ahụ dị jụụ ka a na-edozi ya ma na-agafe n'elu mkpuchi galvanized iji gbochie mmalite oxidation nke elu. Ọnụnọ nke ihe nkiri na-agafe agafe n'elu mkpuchi galvanized ga-egbochi zinc phosphate ma ọ bụ ígwè phosphate pretreatment, na n'ọtụtụ ọnọdụ, na-eme ka usoro ọgwụgwọ ndị a ghara ịdị irè. Ọ dị mkpa na a naghị emenyụ ihe ndị na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ mgbe a mụsịrị ya. Nke a na-eme ka o doo anya na elu zinc dị na ọnọdụ na-emeghachi omume nke ukwuu iji nabata usoro ọgwụgwọ a na-etinye na usoro mkpuchi ntụ ntụ.

3. Ntupu:

• A na-akpata pinholing site n'ichepụta obere afụ gas na mkpuchi polyester n'oge usoro ikpo ọkụ / ọgwụgwọ. Afụ ndị a na-etolite obere craters n'elu ma bụrụ ndị na-adịghị mma. Isi ihe kpatara pin holing yiri ka ọ bụ na ihe ndị dị na polyester resin particles na kọntaktị na galvanized ígwè elu adịghị fuse n'otu oge ahụ dị ka ndị dị n'elu nke polyester ntụ ntụ. ihe nkiri, n'ihi oke nke galvanized ígwè , na oge ewepụtara ya ka ọ bịarute na okpomọkụ nke ngwakọta.
• E mepụtala resins ndị a haziri ahazi nke nwere ihe ndị na-eme ka ikuku na-ekpo ọkụ iji belata nsogbu a site na igbu oge mmalite nke ngwakọta ntụ ntụ. Ịkụnye ọrụ ahụ n'ime oven tupu etinye ya na ntụ ntụ na-enye ohere ka a na-ekpuchi akụkụ dị arọ nke na-ekpo ọkụ na-ekpo ọkụ ma na-edozi nsogbu nke pin holing mgbe ejiri ya na 'degassing' akara ule nke mkpuchi ntụ ntụ polyester.
