I-Zinc uthuli

Ngenxa yobuthi be-chromium ye-hexavalent e-zinc-chromium coatings, amazwe azungeze umhlaba wonke avimba ukukhiqizwa nokusetshenziswa kwengubo equkethe ama-chromium. Ubuchwepheshe be-chromium-aluminium obunamahhala buhlobo olusha lwe- "Green" Surface Treatment Technology. Kuyinto inoveli ye-zinc-aluminium coating eyenza kahle futhi ihlangabezana nezidingo zokuvikelwa kwemvelo, okwenza kube umkhuba wokufaka esikhundleni sezimbali ze-zinc-chromium. Ukukhiqizwa kwezimbali ze-chromium-aluminium ezingenama-zinc-aluminium kudinga izinto ezahlukahlukene ezingavuthiwe, nge-flake zinc powder ngokuba okubaluleke kakhulu.

Zinc | Insimbi yesiliva-grey ngensimbi yensimbi esigabeni sesiphambano, eyakha ungqimba oluminyene lwefilimu ye-zinc carbonate ebusweni bawo ekushiseni kwegumbi, ukuhlinzeka ngemiphumela yokuvikela. Iphoyinti elincibilikayo le-zinc lingu-419.8 ° C, futhi ubuningi balo bungu-701 g / m³. Emazingeni okushisa asekamelweni, kuncipha, kuthambisa ngo-100-150 ° C futhi kuphinde kube ngamazinga okushisa angenhla kwamazinga okushisa angenhla kwama-200 ° C. I-zinc inezindawo ezintathu ze-crystalline: α, β, kanye γ, namazinga okushisa okuguqula ama-170 ° C no-330 ° C. Ukusebenza kukagesi kwe-zinc kungu-27.8% leso sesiliva, futhi ukuvumelanisa kwawo okushisayo kungama-24,3% leso sesiliva.

Izinhlobo zothuli lwe-zinc

Ngokusho kombuso kanye nohlelo lokusebenza, i-zinc powder ingahlukaniswa nge-spherical zinc powder, i-flake zinc powder, kanye ne-zinc-grade yebhethri. Izindlela ezahlukahlukene zokukhiqiza zingakhiqiza ama-zinc powders ezimo ezahlukahlukene, izingoma, kanye nezicelo.

Imibala eminingi yensimbi isebenzisa ama-Flake wensimbi. I-Flake Zinc uthuli yakhiwa izembozo bese ifaka isicelo. I-coating yakha ifilimu endaweni engaphansi komhlaba, lapho uthuli lwensimbi lwe-flake luqondaniswa ezingxenyeni ezihambisanayo ngenhlamvu ehambisana nenhlanganisela, ukudala umphumela wokuvikelwa. Ngenxa yesakhiwo sayo esiyingqayizivele seplanethi ehlukile, uFlake Zinc uthuli kukhombisa ukumboza okuhle, ukunamathela, ukucatshangelwa, kanye nesilinganiso esikhulu se-aspect (50-200).

Izakhiwo ze-Optical | Ama-powders amaningi wensimbi anezakhiwo ezinhle ze-Optical, enye yazo ikhono elibonisa ukukhanya. Isibonelo, ama-zinc-aluminum amboni akhombisa umphumela wensimbi yensimbi.

Izakhiwo Zokuvikela | Lapho i-flake znic uthuli yakhiwa izembozo futhi isetshenziswe ukuze kwakhiwe ifilimu, amathuli wensimbi e-flake aqondanisa nezingqimba ezihambisanayo ngenhlanganisela, ekhiqiza umphumela wokuvikela.

Izakhiwo ezintantayo | OLUNYE olunye isimilo esibalulekile sothuli lwe-flake lun amandla alo ukuntanta, ukuvumela ukuba uhlale ebusweni bezinto ezithwala.

Izakhiwo Ezikhethekile | Ngenxa yesakhiwo sayo esiyingqayizivele seplanethi ehlukile, i-flake zinc dist inembozo enhle kakhulu, ukunamathela, imiphumela ebalulekile yokuvikelwa, kanye nokuvezwa, kanye nokuphikiswa okuvelele kokugqwala.
