Acrylic vs urethane conformal txheej - Polyurethane Conformal Txheej yog dab tsi?

Conformal coatings yog siv rau cov ntawv luam tawm Circuit Board los txhim kho cov cuab yeej kev ntseeg tau thiab ua haujlwm ntev. Cov ntaub ntawv polymeric no tsim cov yeeb yaj kiab uas tiv thaiv hluav taws xob los ntawm kev hem thawj xws li corrosion, kua, thiab av noo. Muaj cov txheej txheem sib txawv, ntawm lawv epoxy, silicone, acrylic, parylene, thiab polyurethane.

Polyurethane conformal txheej yog ib txheej txheej tiv thaiv tawv resistant rau abrasion thiab hnyav. Cov cwj pwm ntawm polyurethane kuj suav nrog

• Roj thiab noo noo tsis kam
• Flexibility li no yooj yim conforms rau txawv duab
• Txaus siab rau qhov ntsuas kub; chav kawm F tshwj xeeb
• Viscosity tso cai rau qhov xav tau thinness kom ua tiav
• Txhim khu hluav taws xob rwb thaiv tsev; khaws cov rwb thaiv tsev nyob rau hauv ib qho kev sim cycling

Cov txiaj ntsig

Polyurethane coatings txuas lub neej ntawm cov cuab yeej los ntawm kev txhim kho lawv. Nws ua kom lawv tuaj yeem ua haujlwm tau zoo txawm tias muaj xwm txheej.

Cov txheej no kuj muaj lub zog thiab ruaj khov, ua rau nws tiv taus cov kuab tshuaj organic thiab av noo.

Cov txheej tawv tawv tiv thaiv txhua yam hnav thiab tseem txo cov tin whisker kev loj hlob.

Cov ntawv thov 

Polyurethane coatings yog qhov zoo tshaj plaws rau cov khoom siv hluav taws xob uas ntsib cov tshuaj lom neeg ntau dhau. Lawv yog cov zoo hauv kev khaws cov generators, transformers, motors, thiab relays, ntawm lwm yam, insulated thiab tiv thaiv.

Cov txheej kuj tseem nrov nyob rau hauv aerospace thiab automotive ib puag ncig. Nws qhov kub tsis kam ua rau nws tiv thaiv cov khoom siv hluav taws xob hauv cov tshuaj ntsev thiab tshuaj lom neeg ib puag ncig.

Los ntawm kev xaiv qhov no conformal txheej hom, koj paub tseeb tias koj cov khoom siv hluav taws xob yuav khiav tau zoo txawm tias nyob hauv ib puag ncig hnyav. Polyurethane tsis tshua muaj kev sib txhuam thiab kev txhuam tsis zoo piv rau lwm cov ntaub ntawv conformal.

Txheej txheej txheej 

Polyurethane conformal txheej yog muaj nyob rau hauv ib tug ob-tivthaiv formulation los yog ib tug compound. Txhuam, tshuaj tsuag, thiab koj tuaj yeem siv txoj hauv kev dipping los siv cov txheej uas xav tau. Tom qab daim ntawv thov, zaj duab xis yog sab laug los kho kom tiav rau txheej txheej txheej kom dhau; qhov no yuav siv li ib teev mus rau ob peb hnub kom tiav. Whereas cov formulations ib leeg yog ib qho yooj yim mus thov, lawv xav tau hnub ua ntej lawv ua tiav thiab npaj siv.

Daim ntawv thov txheej txheem kuj tuaj yeem txiav txim siab los ntawm qhov kub thiab txias uas ua haujlwm tiav. Cov urethane coatings kho sai nyob rau hauv cov cheeb tsam uas qhov kub thiab txias yog nruab nrab. Cov txheej txheem kuj tuaj yeem ua rau catalyzed siv tshav kub thiab UV raug; Qee zaum, kev kho cov dej noo yog lwm txoj hauv kev rau kev sib txuas ntawm cov polymers.

Cov drawbacks 

Polyurethane conformal txheej yog amazing nyob rau hauv cov nqe lus ntawm tsis kam mus ya raws, abrasion, thiab thermal shock. Txawm li cas los xij, nws muaj qhov tsis zoo ntawm txoj kev kho kom ntev. Lub sijhawm kho tom qab tuaj yeem ntev, thiab nws tuaj yeem txiav txim siab cov khoom koj nyiam thaum kawg. Cov coatings kuj zoo li tig daj thaum lawv muaj hnub nyoog; nws tsis yog ib yam dab tsi uas cuam tshuam rau lawv txoj kev ntseeg, tab sis nws tsis yog qhov zoo nkauj.

Xaiv cov khoom zoo sib xws yog qhov tseem ceeb heev vim nws yuav txiav txim siab txog qib kev tiv thaiv koj muab cov cuab yeej ntawm tes. Tshawb nrhiav txhua yam uas koj xav tau txog cov txheej txheem txheej txheem uas muaj thiab cuam tshuam rau koj cov kev xav tau kev tiv thaiv hluav taws xob. Kev paub txog koj tus kheej nrog qhov tsis zoo thiab qhov tsis xws luag kuj ua rau koj nyob hauv txoj haujlwm zoo dua los tswj cov txheej txheem txheej. Txhawm rau txo qhov kev pheej hmoo ntawm kev ua yuam kev hauv daim ntawv thov thiab kho cov txheej txheem, koj tuaj yeem nrhiav kev pabcuam txheej txheej los ntawm cov tuam txhab txhim khu kev qha thiab cov chaw muab kev pabcuam. Nws yog qhov zoo dua li kev pheej hmoo uas tuaj yeem rhuav tshem koj cov khoom siv hluav taws xob thiab lawv cov khoom.
