Acrylic vs urethane conformal coating - Kodi Polyurethane Conformal Coating ndi Chiyani?

Zokutira conformal amagwiritsidwa ntchito pama board osindikizidwa kuti apititse patsogolo kudalirika kwa chipangizocho komanso kukhazikika. Zida za polymeric izi zimapanga filimu yomwe imateteza zamagetsi ku zoopsa monga dzimbiri, zamadzimadzi, ndi chinyezi. Pali zokutira zofananira, pakati pawo epoxy, silikoni, acrylic, parylene, ndi polyurethane.

Polyurethane conformal zokutira ndi zotchinga zolimba zoteteza ku abrasion ndi zosungunulira. Makhalidwe a polyurethane amaphatikizanso

• Kukana mafuta ndi chinyezi
• Kusinthasintha kotero kumagwirizana mosavuta ndi mawonekedwe osiyanasiyana
• Kutentha kochititsa chidwi; kalasi F mwachindunji
• Viscosity imalola kuonda komwe kumafunidwa kuti kutheke
• Odalirika kusungunula magetsi; amasunga zotsekemera pamayeso apanjinga

Madalitso

Zovala za polyurethane zimakulitsa moyo wa chipangizocho powawonjezera. Imawonetsetsa kuti atha kugwira ntchito modalirika mosasamala kanthu za momwe zinthu ziliri.

Kupaka uku kumakhalanso ndi mphamvu komanso kulimba, zomwe zimapangitsa kuti zisagwirizane ndi zosungunulira za organic ndi chinyezi.

Chophimba cholimbacho chimatsutsana ndi kuvala kwamakina komanso chimachepetsa kukula kwa ndevu za malata.

Ntchito 

Zovala za polyurethane ndizoyenera kwambiri pamagetsi omwe amayang'anizana ndi kuwonekera kwa mankhwala. Ndiabwino kusunga ma jenereta, ma transfoma, ma mota, ndi ma relay, pakati pazigawo zina, zotetezedwa komanso zotetezedwa.

Chophimbacho chimatchukanso m'malo opangira ndege komanso magalimoto. Kutentha kwake kumapangitsa kuti ikhale yotetezera kumagetsi mumchere wopopera mchere ndi malo a mankhwala.

Posankha izi zokutira conformal mtundu, mukutsimikiza kuti zinthu zanu zamagetsi ziziyenda modalirika ngakhale m'malo ovuta. Polyurethane ndi yotsika pakukangana komanso kukana ma abrasion poyerekeza ndi zida zina zofananira.

Njira yokutira 

Polyurethane conformal yokutira imapezeka muzinthu ziwiri kapena pawiri imodzi. Kupaka, kupopera mbewu mankhwalawa, ndipo mutha kugwiritsa ntchito njira zoviika kuti mugwiritse ntchito wosanjikiza ngati pakufunika. Pambuyo pakugwiritsa ntchito, filimuyo imasiyidwa kuti ichiritse kwathunthu kuti ndondomeko yokutira ithe; izi zimatenga pafupifupi ola limodzi mpaka masiku angapo kuti amalize. Ngakhale kuti chigawo chimodzi ndi chosavuta kugwiritsa ntchito, chimatenga masiku angapo chisanamalizidwe ndikukonzekera kugwiritsidwa ntchito.

Njira yogwiritsira ntchito imathanso kutsimikiziridwa ndi kutentha komwe ntchitoyo ikugwira. Zovala za urethane zimachiritsa mofulumira m'madera omwe kutentha kumakhala kokwera kwambiri. Njirayi ingathenso kuthandizidwa pogwiritsa ntchito kutentha ndi kuwala kwa UV; nthawi zina, kuchiritsa chinyezi ndi njira ina yolumikizira ma polima.

Zolepheretsa 

Polyurethane conformal zokutira ndizodabwitsa pankhani ya kukana chinyezi, abrasion, ndi kugwedezeka kwamafuta. Komabe, ili ndi kuipa kwa njira yayitali yochiritsa. Nthawi yochiritsa pambuyo pake imatha kukhala yayitali, ndipo imatha kutsimikizira zomwe mumakonda pamapeto pake. Zopakazo zimakhalanso zachikasu zikamakalamba; sichinthu chomwe chimakhudza kudalirika kwawo, koma sizosangalatsa.

Kutsiliza 

Kusankha zinthu zoyenera ndizofunikira kwambiri chifukwa kumatsimikizira kuchuluka kwa chitetezo chomwe mumapereka zida zomwe zili pafupi. Dziwani zonse zomwe mungafune pazosankha zomatira zomwe zilipo ndipo zigwirizane ndi zosowa zanu zachitetezo chamagetsi. Kudziwa zovuta ndi zolakwika zomwe zingatheke zimakupangitsani kuti mukhale ndi mwayi wosamalira ndondomeko yophimba. Kuti muchepetse mwayi wopanga zolakwika pakugwiritsa ntchito ndikuchiritsa, mutha kufunafuna ntchito zomatira zovomerezeka kuchokera kumakampani odalirika ndi othandizira. Ndi bwino kusiyana ndi kutenga chiopsezo chomwe chingawononge magetsi anu ndi zigawo zake.

Kuti mudziwe zambiri za zokutira za acrylic vs urethane conformal - polyurethane conformal zokutira ndi chiyani, mutha kupita ku DeepMaterial pa https://www.epoxyadhesiveglue.com/what-is-polyurethane-conformal-coating-and-what-is-the-purpose-of-it/ chifukwa Dziwani zambiri.
