Tout sa ou bezwen konnen sou kouch poud

Kouch poud se yon pwosesis fini sèk ki te vin trè popilè depi entwodiksyon li nan Amerik di Nò nan ane 1960 yo. Soti nan machin lave ak sechwa rad rive nan otomobil, balistrad, kloti ak plis ankò, yo fabrike anpil pwodwi ak yon sifas ki kouvri poud-.

Nan atik sa a, tout sa ou bezwen konnen sou kouch poud yo pral prezante.

Ki sa ki se poud kouch?

Powder Coating se yon fason pou koulè diferan sifas tankou metal, konkrè, asye ak plastik. Fason li travay se ke poud nan yon koulè sèten flite sou sifas la, ki kenbe yon chaj elektrik. Chaj la lakòz poud lan konfòme yo ak sifas la, epi li kwit sou yon fwa flite a fini. Konpare ak penti abazde, kouch poud se yon apwòch ki pi avanse - li pote durability amelyore, yon enpak redwi anviwònman an, ak yon aparans pi bon kalite.

Ki jan kouch poud travay?

When a product is powder coated, it's sprayed with pressurized dry powder that sticks to the product's surface. This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part.

Apre aplikasyon kouch poud la, pati yo antre nan yon fou geri kote, ak adisyon nan chalè, kouch la pwodui chimikman reyaji pou pwodui chèn molekilè long, sa ki lakòz gwo dansite kwa -. Chèn molekilè sa yo trè rezistan nan pann. Etap sa a se geri. An jeneral, geri a fèt nan 400 F pou apeprè 20-30 minit depann sou pati a.

Surface preparation/pretreatment is also essential for achieving a successful powder-coating outcome. This normally entails the removal of grease, oil, dirt and other materials via chemical, physical or mechanical methods to clean the surface and promote coating adhesion. Pretreating the workpiece with chemical compounds can enhance the coating's performance, durability and corrosion resistance.

Kalite aplikasyon sa a se metòd ki pi komen pou aplike poud. Kouch poud ka itilize nan substrats metal tankou Nerjaveèi oswa aliminyòm, oswa ki pa -substra metalik tankou plastik ak fibr dansite mwayen.

Kalite kouch poud

Gen de kalite prensipal nan kouch poud, sètadi, tèrmoplastik ak tèrmoset.

The thermoplastics variety does not undergo any additional reactions during the baking process, but rather only flows out into the final coating. Thermoplastics pellets soften when heated and become more fluid as additional heat is applied. The curing process is completely reversible as no chemical bonding takes place. This characteristic allows thermoplastics to be remolded and recycled without negatively affecting the material's physical properties. There are multiple thermoplastic resins that offer various performance benefits, but most materials commonly offer high strength, shrink-resistance and easy bendability. Depending on the resin, thermoplastics can serve low-stress applications such as plastics bags or high-stress mechanical parts.

Varyete tèrmoset yo enkòpore yon kwa-linker nan fòmilasyon an. Pwosesis kwa-reliye a elimine risk pou pwodwi a refonn lè yo aplike chalè, sa ki fè thermosets ideyal pou aplikasyon pou gwo-chalè tankou elektwonik ak aparèy. Lè poud lan kwit, li reyaji ak lòt gwoup chimik nan polymère poud la ak ogmante pwa molekilè a ak amelyore pwopriyete pèfòmans yo, kidonk li enposib resikle poud thermoset. Anplis, kouch thermoset yo souvan pi bon mache nan de la.

Ki sa ki kouch poud itilize pou?

Depi syantifik Alman Dr Erwin Gemmer te devlope kouch poud nan ane 1940 yo, li te itilize pa nenpòt ak tout endistri ki sèvi ak metal, endistri boutèy la pa gen okenn eksepsyon.

Kouch poud vin pi plis ak plis popilè jou sa yo pou boutèy izole asye pur. Gen plizyè avantaj nan kouch kouch poud: anti-glise, dirab ak kolore. Kòm yon dirijan vakyòm izole asye pur boutèy dlo manifakti, GiNT gen eksperyans rich nan pwosesis kouch poud, epi li bay yon gwo kantite gwo -bon jan kalite boutèy poud kouvwi.
