Amfani da silica a cikin shafa ya ƙunshi inganta mannewa, juriya ga yanayi, hana daskarewa, da kuma haɓaka thixotropy. Ya dace da shafan gine-gine, shafan ruwa, da fenti na resin acrylic.
I. Dacewar Nau'in Silica da Tsarin Shafawa
1. Silica mai ƙura
Yankunan Amfani: Rufin da za a iya warkar da shi ta hanyar UV (misali, rufin katako na UV, rufin filastik na UV), rufin da aka yi da fim mai kauri na masana'antu, da kuma rufin foda.
Amfanin Aiki: Ƙarfin thixotropy, kyakkyawan tasirin hana sagging da hana daidaitawa.
Tasirin Farashi: Duk da cewa farashin naúrar yana da yawa, yawan da ake buƙata yana da ƙasa (0.5%–3%), wanda hakan ke sa farashin gaba ɗaya ya zama mai sauƙin sarrafawa.
2. Silica mai ambaliya
Yankunan Amfani: Rufin gine-gine, rufin masana'antu na matsakaici zuwa ƙasa.
Fa'idodin Aiki: Ƙananan farashi, kodayake ana buƙatar ƙarin sashi (3%–10%); ingantaccen tasirin matting idan aka kwatanta da silica mai hayaƙi.
Iyakoki: Rarraba girman barbashi mai faɗi, ƙarancin daidaito a cikin sarrafa rheology.
3. Silica Aerogel
Aikace-aikace na Musamman: Rufin da ke hana wuta, murfin kariya ga kayan aiki masu zafi sosai.
Matsalar Kuɗi: Tsarin shiri mai sarkakiya; farashin ya kai dubban RMB/kg, don haka ana amfani da shi ne kawai a fannoni masu ƙima.
II. Ingantawa ga Aikin Rufi
1. Inganta Aikin Rheology da Aikace-aikace
Silica mai hayaƙi yana samar da tsarin hanyar sadarwa mai girma uku ta hanyar ƙungiyoyin hydroxyl na saman, yana haifar da thixotropy: ƙarƙashin ƙarfin yankewa, danko yana raguwa don sauƙaƙe amfani; lokacin da ba ya canzawa, danko yana murmurewa don hana lanƙwasawa da taruwar gefen. Silica mai tsatsa yana ƙara kwanciyar hankali na rufi, yana hana daidaita launin, kuma yana tsawaita tsawon lokacin ajiya.
2. Hana Caking da Inganta Watsawa
Ultrafine silica, a matsayin ƙarin abu na waje, yana shaƙa a saman murfin foda don ƙirƙirar "tasirin ɗaukar ƙwallo," yana inganta kwarara da juriya ga caking. Ƙarfin saman silica mai ƙarfi yana rage lokacin warwatsewa kuma yana inganta daidaiton launin.
3. Inganta Aiki
Tasirin Matting: Ƙananan ƙwayoyin silica suna rage sheƙi ta hanyar haskakawa mai yaɗuwa, suna cimma kammala matte zuwa semi-matte.
Halayen Inji: Yana inganta taurin shafi, juriyar gogewa, da juriyar yanayi, yana tsawaita tsawon lokacin aiki.
Kayayyakin gani: Yana inganta watsawar UV don hana tsufa yayin da yake kiyaye bayyananne.
4. Yanayi na Musamman na Aikace-aikace
Rufin fim mai kauri (misali, fenti na ruwa): Ya dogara da silica thixotropy mai hayaƙi don tabbatar da kauri fim ɗin.
Rufin bene: Inganta daidaito da juriyar karce.
Zaɓin Nau'i: Ya kamata a zaɓi nau'ikan silica daban-daban (wanda aka yi da hayaki/wanda aka yi da hayaki) bisa ga buƙatun shafi—misali, silica mai hayaki don sarrafa rheology daidai, yayin da silica mai hayaki yana ba da daidaiton aiki mai kyau a cikin matting.
III. Shawarwari don Daidaita Farashi da Aiki
Rufin da ke da inganci (misali, rufin mota, rufin UV): An fi son silica mai hayaƙi, duk da yawan farashinsa, domin yana ƙara aiki sosai (misali, ninka juriyar gogewa).
Rufin tsakiya zuwa ƙasa (misali, rufin gine-gine): Silica mai ruwa yana ba da mafi kyawun rabon aiki da farashi, kuma ana iya inganta jituwa ta hanyar gyara saman.
Bukatun aiki na musamman (rufewar wuta/zafin zafi): Silica airgel ba za a iya maye gurbinsa ba amma yana buƙatar cikakken kimantawa game da ingancin farashi.
Kammalawa: A masana'antar rufe fuska, silica tana rage farashi gaba ɗaya a kaikaice ta hanyar inganta aiki. Duk da haka, dole ne a daidaita farashin kayan masarufi da saka hannun jari a cikin tsari. Aikace-aikacen da aka yi amfani da su a manyan fannoni suna amfani da silica mai hayaki, yayin da kasuwannin tsakiya zuwa ƙananan ke fifita silica mai haƙa don ingantaccen inganci.
