Isticmaalka silica ee dahaarka waxaa inta badan ku lug leh hagaajinta isku-dhejinta, iska caabbinta cimilada, sifooyinka ka hortagga degitaanka, iyo xoojinta thixotropy. Waxay ku habboon tahay dahaarka dhismaha, dahaarka biyaha ku salaysan, iyo rinjiga resin acrylic.
I. Waafaqsanaanta Noocyada Silica iyo Nidaamyada Dahaarka
1. Silica la shiiday
Meelaha Loo Adeegsado: Dahaarka UV-ga ee la daweyn karo (tusaale ahaan, dahaarka alwaaxa UV, dahaarka balaastikada UV), dahaarka filimada qaro weyn ee warshadaha, iyo dahaarka budada.
Faa'iidooyinka Waxqabadka: thixotropy xooggan, saameyn aad u fiican oo ka hortagga hoos u dhaca iyo ka hortagga degitaanka.
Saamaynta Kharashka: Inkasta oo qiimaha halbeeggu uu sarreeyo, qiyaasta loo baahan yahay waa mid hooseysa (0.5%–3%), taasoo ka dhigaysa kharashka guud mid la xakameyn karo.
2. Silica roobka wata
Meelaha lagu dabaqo: Dahaarka dhismaha, dahaarka warshadaha ee dhexdhexaadka ah ilaa kuwa hoose.
Faa'iidooyinka Waxqabadka: Kharash yar, inkastoo loo baahan yahay qiyaas sare (3%–10%); saameyn ka wanaagsan oo isku-darka marka loo eego silica la shiiday.
Xaddidaadaha: Qaybinta cabbirka walxaha ballaaran, saxnaanta hoose ee xakamaynta rheology.
3. Silica Aerogel
Adeegsiyo Gaar ah: Dahaarka dabka ka ilaaliya, dahaarka ilaalinta qalabka heerkulka sare leh.
Arrinta Kharashka: Habka diyaarinta oo adag; qiimuhu wuxuu gaarayaa tobanaan kun oo RMB/kg, sidaas darteed waxaa loo isticmaalaa oo keliya goobaha qiimaha sare lagu daray.
II. Hagaajinta Waxqabadka Dahaadhka
1. Hagaajinta Waxqabadka iyo Rheology-ga
Silica la shiiday waxay samaysaa qaab-dhismeed shabakad saddex-geesood ah iyada oo loo marayo kooxaha dusha sare ee hydroxyl, taasoo keenta thixotropy: marka la xiiro xoogga, viscosity-gu wuu yaraadaa si loo fududeeyo codsiga; marka uu taagan yahay, viscosity-gu wuu soo kabsadaa si looga hortago libdhashada iyo ururinta geesaha. Silica la shiiday waxay xoojisaa xasilloonida dahaarka, waxay ka hortagtaa dejinta midabka, waxayna dheereysaa cimriga kaydinta.
2. Ka-hortagga Qashin-qubka iyo Firdhinta oo la Hagaajiyay
Silica aad u fiican, oo ah wax lagu daro dibadda, waxay ku nuugtaa dusha sare ee dahaarka budada si ay u abuurto "saameyn kubbadeed," taasoo hagaajinaysa socodka iyo iska caabbinta dubista. Tamarta sare ee silica la shiiday waxay soo gaabinaysaa waqtiga kala firdhinta waxayna hagaajinaysaa isku midnimada midabka.
3. Horumarinta Waxqabadka
Saamaynta isku-dhafka: Qaybaha yaryar ee silica waxay yareeyaan dhalaalka iyada oo loo marayo milicsiga kala-baxa, iyagoo gaaraya dhammaystirka matte ilaa nus-matte.
Sifooyinka Farsamada: Waxay hagaajisaa adkaanta dahaarka, iska caabbinta xoqidda, iyo iska caabbinta cimilada, iyadoo dheereyneysa cimriga adeegga.
Astaamaha Indhaha: Waxay kor u qaaddaa kala firdhinta UV si ay u ilaaliso awoodda gabowga iyadoo la ilaalinayo hufnaanta.
4. Xaaladaha Codsiga Gaarka ah
Dahaarka filimka qaro weyn (tusaale ahaan, rinjiga badda): Ku tiirsanow thixotropy silica ah oo la shiiday si loo hubiyo dhumucda filimka.
Dahaarka sagxadda: Hagaaji heerka iyo iska caabbinta xoqidda.
Xulashada Nooca: Noocyada kala duwan ee silica (qiiq/daad) waa in la doortaa iyadoo lagu saleynayo shuruudaha dahaarka - tusaale ahaan, silica la shiiday si loo xakameeyo rheology-ga saxda ah, halka silica la shiiday ay bixiso dheelitirnaan kharash-waxqabad oo wanaagsan oo ku saabsan matting-ka.
III. Talooyin ku saabsan Isu-dheellitirka Qiimaha iyo Waxqabadka
Dahaarka sare (tusaale ahaan, dahaarka baabuurta, dahaarka UV): Silica la shiiday ayaa la doorbidaa, inkastoo qiimaha cutubku sarreeyo, maadaama ay si weyn u wanaajiso waxqabadka (tusaale ahaan, labanlaab u adkeysiga xoqidda).
Dahaarka dhexe ilaa hoose (tusaale ahaan, dahaarka dhismaha): Silica roobka leh waxay bixisaa saami wanaagsan oo kharash-waxqabad ah, iswaafajintana waxaa lagu hagaajin karaa iyada oo loo marayo wax ka beddelka dusha sare.
Shuruudaha shaqada gaarka ah (dab-damis/kuleyl-dab-damis): Silica aerogel lama beddeli karo laakiin waxay u baahan tahay qiimeyn dhammaystiran oo ku saabsan waxtarka kharashka.
Gunaanad: Warshadaha dahaarka, silica waxay si dadban u yareysaa kharashka guud iyadoo kor u qaadaysa waxqabadka. Si kastaba ha ahaatee, qiimaha alaabta ceeriin iyo maalgashiga habka waa in la dheellitiraa. Codsiyada heerka sare ah waxay u janjeeraan inay isticmaalaan silica la shiiday, halka suuqyada dhexe ilaa kuwa hoose ay doorbidaan silica la shiiday si loo helo kharash-oolnimo wanaagsan.
