Guryaha microspheres galaas godan iyo noocyadooda caagga ah ee lagu dabaqi karo

Microspheres galaas madhanwaa microspheres muraayadaha si gaar ah loo farsameeyey, kuwaas oo inta badan lagu garto cufnaanta hoose iyo kulaylka liidata marka loo eego microspheres galaas ah.Waa nooc cusub oo ah walxo fudud oo mikron ah oo la sameeyay 1950-meeyadii iyo 1960-meeyadii.Qaybteeda ugu muhiimsan waa borosilicate, oo leh cabbir guud oo ah 10 ~ 250μm iyo dhumucdiisuna tahay 1 ~ 2μm;Kuul quraarad ah oo godan ayaa leh Waxay leedahay sifooyinka xoogga cufan ee sarreeya, barta dhalaalka sare, caabbinta sare, iyo kororka kulaylka yar iyo iskudhafka kuleylka kuleylka.Waxaa loo yaqaan "space age material" qarnigii 21aad.Microspheres galaas madhanwaxay leeyihiin hoos u dhigista miisaanka cad iyo dahaarka dhawaaqa iyo saamaynta kulaylka, si ay alaabadu u leeyihiin waxqabadka wanaagsan ee ka hortagga dildilaaca iyo waxqabadka dib u habeynta, waxaana si weyn loogu isticmaalaa walxaha isku dhafan sida fiber galaas ah oo la xoojiyay, marmar macmal ah, agate macmal ah, iyo sidoo kale in warshadaha batroolka, aerospace iyo aerospace warshadaha., tareeno cusub oo xawaare sare leh, baabuurta iyo maraakiibta, dahaarka kulaylka iyo qaybaha kale ayaa si wax ku ool ah kor u qaaday horumarinta hawlaha sayniska iyo teknoolajiyada ee dalkayga.Si loo buuxiyo shuruudaha dielectric hooseeya, luminta yar iyo miisaanka fudud ee qalabka isgaarsiinta 5G, microspheres galaas godan ayaa sidoo kale ka ciyaara door muhiim ah oo sii kordheysa sababtoo ah kharashkooda hooseeya iyo waxqabadkooda wanaagsan.

1 – Waxyaabo

Halabuurka kiimikaad ee mikrospheres galaas godan (saamiga tirada)

SiO2: 50% -90%, Al2O3: 10% -50%, K2O: 5% -10%, CaO: 1% -10%, B2O3: 0-12%

2- Astaamaha

midab saafi cad

Waxaa si weyn loogu isticmaali karaa alaab kasta oo leh shuruudo ku saabsan muuqaalka iyo midabka.

3- cufnaanta iftiinka

Cufnaanta mikrospheres galaas godan ayaa ah ilaa toban meelood meel cufnaanta walxaha buuxinta dhaqameed.Ka dib marka la buuxiyo, miisaanka aasaasiga ah ee alaabta si weyn ayaa loo dhimi karaa, resins wax soo saar badan ayaa la bedeli karaa oo la badbaadin karaa, qiimaha alaabtana waa la dhimi karaa.

4-Daacadnimo

Microspheres galaas madhan way fududahay in la qoyo oo la firdhiyo, waxaana lagu buuxin karaa inta badan resins thermoplastic, sida polyester, resin epoxy, polyurethane, iwm.

5-Dhaqdhaqaaq wanaagsan

Maaddaama microspheres muraayadaha bannaan ay yihiin qaybo yaryar, waxay leeyihiin dareere ka wanaagsan xabagta dareeraha ah marka loo eego jeexjeexyada, irbadda ama buuxinta aan caadiga ahayn, sidaa darteed waxay leeyihiin waxqabadka buuxinta caaryada wanaagsan.Tan ka sii muhiimsan, microbeads-yada yaryar waa isotropic, sidaa daraadeed ma jirto wax khasaare ah oo ka mid ah heerarka hoos u dhaca ee qaybaha kala duwan sababtoo ah jihada, taas oo hubinaysa xasiloonida cabbirka ee badeecada oo aan ku dhicin.

6- Xakamaynta kulaylka iyo dhawaaqa

Gudaha gudaha microspheres galaas godan waa gaas dhuuban, sidaas darteed waxay leedahay sifooyin dahaarka dhawaaqa iyo kuleylka kulaylka, waana buuxinta ugu fiican ee dahaarka kulaylka ee kala duwan iyo alaabada ilaalinta dhawaaqa.Sifooyinka dahaarka ee microspheres galaas godan ayaa sidoo kale loo isticmaali karaa si looga ilaaliyo alaabta shoogga kulaylka ee ay keento beddelka u dhexeeya kuleylka degdega ah iyo xaaladaha qaboojinta degdegga ah.Iska caabin gaar ah oo sarreeya iyo nuugista biyaha aadka u hooseeya ayaa ka dhigaysa in si weyn loogu isticmaalo soo saarista walxaha dahaadhka fiilada.

7- Saliida nuugista oo yaraata

Qaybaha wareega ayaa go'aamiya inay leedahay meesha ugu yar ee gaarka ah ee dusha sare iyo heerka nuugista saliidda oo hooseeya.Inta lagu jiro habka isticmaalka, qadarka resin si weyn ayaa loo dhimi karaa, iyo viscosity ma kordhin doono wax badan xitaa iyada oo la adeegsanayo qadarka sare ee qadarka sare, taas oo si weyn u hagaajinaysa xaaladaha wax soo saarka iyo hawlgalka.Kordhi waxtarka wax soo saarka 10% ilaa 20%.

8- Dielectric joogto ah oo hooseeya

Qiimaha Dk ee mikrospheres galaas godan waa 1.2 ~ 2.2 (100MHz), kaas oo si wax ku ool ah u wanaajin kara sifooyinka dielectric ee walxaha.

Caagagga loogu talagalay kuul quraarad ah oo bannaan

(1) Wax ka beddelka balaastikada injineernimada sida naylon, PP, PBT, PC, POM, iwm, waxay hagaajin kartaa dareeraha, baabi'in kartaa soo-gaadhista fiber-ka galaaska, ka adkaanta warwarka, hagaajinta waxqabadka ololka, yaraynta isticmaalka fiber-ka galaaska, waxayna yaraynaysaa wax soo saarka kharashka

(2) Buuxinta PVC adag, PP, PE, iyo soo saarista alaabta profiled, tuubooyinka iyo taarikada waxay ka dhigi kartaa alaabtu inay yeeshaan xasillooni cabbir wanaagsan, hagaajinta qallafsanaanta iyo heerkulka iska caabbinta kulaylka, hagaajinta waxqabadka kharashka alaabta, hagaajinta waxtarka wax soo saarka waxayna yareeyaan kharashyada.

(3) Buuxinta PVC, PE iyo fiilooyinka kale iyo walxaha galka dahaarka ah waxay hagaajin karaan caabbinta heerkulka sare ee sheyga, dahaarka, caabbinta aashitada iyo alkali iyo guryaha kale iyo waxqabadka badeecada, kordhinta wax soo saarka iyo dhimista kharashyada.

(4) Buuxinta saxan maro naxaas ah resin resin epoxy yarayn kartaa viscosity of resin ah, kordhinta xoogga foorarsiga, hagaajinta sifooyinka jireed iyo farsamada, kordhinta heerkulka kala guurka galaas, la yareeyo joogto ah dielectric ah, hoos u nuugista biyaha, iyo in la yareeyo kharashka .

(5) Ku-buuxinta polyester-ka aan dheregsanayn waxay yarayn kartaa heerka yaraanta iyo heerka biyaha dhaqida badeecadda, waxay hagaajinaysaa caabbinta xidhashada iyo adkaanta, oo waxay yeelan kartaa godadka godadka inta lagu jiro dahaarka iyo dahaadhka.Waxaa loo isticmaalaa alaabada FRP, taayirrada dhalaalaya, qalabka, iwm.

(6) Ku-buuxinta resin silicone waxay hagaajin kartaa sifooyinka jirka iyo farsamada, iyo qadar badan oo buuxin ah ayaa si weyn u yareyn kara qiimaha, taas oo ah wax ku habboon wax soo saarka caaryada.
