Dahaarka budada ah ee shaqaynaya:Dahaarka budada ah ee dahaaran iyo wax-qabadka
The dusha budada waa nooc cusub oo ah 100% daahan adag oo aan dareere lahayn. Leh dareere-free, aan wasakhayn, dib loo warshadayn karo, deegaanka saaxiibtinimo, badbaadinta tamarta iyo khayraadka, iyo yaraynaysaa xoogga shaqada iyo xoogga farsamada filimka. Foomka dahaarka iyo samaynta xayndaabyada adag ee ilaa 100%, sababtoo ah ma isticmaalaan dareeraha, taas oo yaraynaysa wasakhowga deegaanka, ilaalinta khayraadka iyo sifooyinka dib loo warshadayn karo.
The dahaarka budada functional waa shaqo gaar ah, alaabta daahan oogada si ay u bixiyaan ujeedooyin gaar ah. Ma aha oo kaliya inay ciyaari karto doorka dhaqameed ee ilaalinta iyo qurxinta, iyo sidoo kale waxay siisaa walxaha noocyo kala duwan oo hawlo gaar ah, oo ay ku jiraan dahaarka, korantada, wasakhowga ka hortagga, kulaylka, ololka ololka, ilaalinta shucaaca iyo hawlaha kale.
Horumarinta iyo soo saarista dahaarka budada ah ee shaqeynaya ayaa hadda bilowday, walina aad bay uga dambeeyaan heerka sare ee shisheeye. Hiddaha dahaarka budada ah ee sida caadiga ah loo isticmaalorally leeyihiin noocyada soo socda:
Dahaarka budada ah ee dahaaran
Dahaarka budada dahaarka Dahaar gaar ah ayaa loo isticmaalaa matoorada, korantada iyo qaybaha elektiroonigga ah, marka lagu daro ilaalinta hiddaharal dahaarka budada, sifooyinka qurxinta, laakiin sidoo kale waxay leedahay sifooyin koronto oo wanaagsan.
Resins Epoxy waa alaab aad u fiican oo loogu talagalay soo saarista daahan budada ah ee dahaarka ah.By bedesho nooca wakiilka daaweynta, ama ku dar wax ka beddelka gaarka ah iyo kulaylka wanaagsan iyo caabbinta kulaylka ee buuxinayaasha si loo hagaajiyo heerka daaweynta, laga helay mid aad u jilicsan, dabacsan, aad u adag. , xidho dahaar kala duwan si ay ula qabsadaan xaaladaha dahaarka kala duwan. Sanadihii la soo dhaafay, marka laga reebo daahan budada epoxy, daahan budada polyurethane, daahan budada of polyimide, daahan budada acrylic, iwm ayaa sidoo kale si joogto ah u horumariyo oo la isticmaalo.
Dahaarka budada wax qabad leh
Dahaarka budada ah ee korantada waxaa lagu dabaqaa substrate-ka aan shaqaynayn, si ay u leedahay qaar ka mid ah socodka hadda jira iyo baabi'inta awoodda korantada ee dahaarka shaqada. Dahaarka noocan oo kale ah inta badan waa laba nooc: nooca isku dhafka ah iyo nooca gudaha
Daahan budo ah oo la isku daray ayaa dahaaran daahan polymer daahan walxaha samaynta, samaynta taas oo isku darka ee buuxinta conductive. Buuxiyaha waxtarka leh, budada birta, sida silver, nikkel, zinc, aluminium, iwm.; aan-metallic budada, sida graphite, kaarboon madow; oxides biraha ah sida zinc oxide, antimony oxide. Xireeyaha Dooro xabagta vinyl, xabagta polyester-ka, polyamide iyo resin epoxy.
polymer conductive gudaha waa polymer-ka laftiisa waa maamule, fasalka hadda ee polymer ayaa weli ku jira aragtida iyo marxaladda cilmi-baarista, ma jiro codsi la taaban karo.
Dahaarka budada lidka ku ah
Hadda la isticmaalayo daahan noocan oo kale ah epoxy phenolic anti-daxalka budada ah waxaa daahan oo leh epoxy resin iyo phenolic resin-ku salaysan filimada-samaynta walxaha, labada iskutallaab formation of daahan. Rinjiga noocaan ah ee loo isticmaalo epoxy-ga waa hidde-siderally loo isticmaalo in noocyada polymer ee miisaanka kelli ee 1400,2900 iyo 3570. Epoxy resin laftiisa, adhesion, dabacsanaan iyo caabbinta alkali iyo wanaagsan, iyo phenolic xabagta leh acid aad u fiican, dareere, kulaylka, huurka waxqabadka qabow ayaa la isku daraa si ay u noqdaan anti-daxalka agabka noocyada ugu fiican. Falcelinta daciifka ah ee udhaxeysa epoxy iyo phenolic resin dahaarka filimka daaweynta heerkulka looga baahan yahay xaaladaha sare, iyadoo lagu darayo qadarka ku haboon ee kicinta imidazole si loo yareeyo heerkulka daaweynta
Dahaarka budada kulaylka u adkaysta
Daahan budo ah oo kulaylka u adkaysata waxay muddo dheer u adkeysan kartaa heerkulka ka sarreeya 200 ℃, filim wanaagsan, oo ka dhigaya shayga ilaalinta heerkulka sare ee deegaanka si uu si habboon u shaqeeyo.
Laga soo bilaabo habka marka loo eego xasilloonida kuleylka polymer, iska caabbinta kulaylka polymer waxay kuxirantahay qaab dhismeedka molecular. Sidaa darteed, kordhinta xoogga isdhexgalka intermolecular by soo bandhigida kooxo waaweyn ama ka badan oo dhinaca ah ee silsiladda ugu weyn, taas oo kor u qaadeysa xasiloonida kulaylka ee polymerka. Hab kale ayaa ah in la wanaajiyo iska caabbinta kulaylka ee dahaarka budada ah iyadoo lagu darayo midabada kulaylka u adkaysta iyo buuxinta polymer-ka. Inta badan loo isticmaalo midabada, buuxinayaashu waa budada aluminium, budada mica, budada birta ah, budada cadmium, silica. Waqtigan xaadirka ah, dahaarka budada ah ee kulaylka u adkaysta ayaa weli ah dahaarka budada silikoon. Tani daahan jihada ugu weyn ee awoodda horumarinta cilmi mustaqbalka ee heerkulka sare iyo waxa uu leeyahay filim samaynta wanaagsan iyo waxqabadka dhismaha ee xabagta heerkulka sare sida alaabta aasaasiga ah ee daahan kulaylka u adkaysta, iyo sidoo kale cilmi-baarista si weyn u hagaajin kara waxqabadka kala duwan ee saldhigga. walxaha xaaladaha heerkulka sare midabada, buuxinta, noocyo cusub.
Dahaarka budada qurxinta
Daahan budada ah ee qurxinta waxaa lagu gartaa in lagu daboolo dusha sare ee muuqaalka cad ee qaabka si ay u walaxda daahan yihiin qurux badan oo midab leh. Habka samaynta daahan budada ah ee qaabka iyo rinji ku salaysan dareeraha ayaa aad u kala duwan. Daahan budada ah waxay isticmaashaa sifooyinkeeda dhalaalidda ee saameynta texture, qaababka qaabka iyo cabbirka, isku dhafka cuntada, farsamada diyaarinta iyo xajmiga walxaha budada.
Isku darka Formula ee xabagta synthetic, wakiilada daweynta, wakiilada sinnaanta, pigments iyo daroogooyinka kala duwan, ayaa ah qodobka ugu muhiimsan ee samaynta qaababka. Siyaabaha loo horumariyay si aad u lahaato fikradaha muhiimka ah ee soo socda:
- isticmaalka polymers-ka aan ku habboonayn si loo soo saaro xaalad socodka, samaynta dareenka saddex-geesoodka ah ee qaabka;
- heerka daaweynta kala duwan ee wakiilka daweynta, ay sabab u tahay farqiga u dhexeeya xawaaraha si ay u sameeyaan laalaab ku habboon;
- Iyada oo buuxinayayaal kala duwan, taasoo keentay heerka daahan budada, gloss iyo kala duwanaansho hue, taasoo keentay saamaynta texture;
- granularity kala duwan iyo hooska kala duwan ee pigments macdan ee daahan in meel ka duwan, xaglo kala duwan, taasoo keentay in kala duwanaansho gloss iyo hue.
Jaakad budada ah ee ololka celisa
Xakamaynta ololka polymer sare ee xaddidan, si loo hagaajiyo dib u dhaca ololka polymers-ka ayaa muhiimad wax ku ool ah u leh dhinacyo badan oo arji ah. Daaharada budada ah ee ololka celisa ee shaqada dab-demiska iyo dab-demiska. Iyada oo horumarinta degdega ah ee qalabka casriga ah ee elektiroonigga ah iyo warshadaha qalabka, shuruudaha dahaarka dab-demiska waa mid degdeg ah. Noocyada ugu muhiimsan ee daahan waa daahan budada epoxy.
Daahan budada functional waa nooc gaar ah oo ka mid ah qalabka functional ka ciyaara door muhiim ah oo sii kordheysa ee dhinacyo badan oo sayniska iyo technology, difaaca, warshadaha iyo beeraha.ral. Of farqiga la dalalka shisheeye in alaabta sida horumariyo waaweyn, waa in aan xoojiso dadaalka si ay u horumariyaan iyo si ay u horumariyaan saamayn functional of ove si weyn u sarreeya.rall waxqabadka, qiimaha jaban, rinjiyeynta dahaarka budada functional si loo daboolo baahida horumarinta dhaqaalaha qaranka.
