Maonekedwe a magalasi opanda kanthu a galasi ndi mitundu yawo yogwiritsira ntchito pulasitiki

Magalasi opanda ma microspheres ndi magalasi opangidwa mwapadera, omwe amadziwika kwambiri ndi kachulukidwe kakang'ono komanso kusayenda bwino kwamafuta kuposa magalasi agalasi. Ndi mtundu watsopano wazinthu zopepuka zazing'ono zomwe zidapangidwa mu 1950s ndi 1960s. chigawo chake chachikulu ndi borosilicate, ndi ambiri tinthu kukula kwa 10 ~ 250μm ndi khoma makulidwe a 1 ~ 2μm; Mikanda yagalasi yopanda kanthu imakhala ndi mawonekedwe amphamvu yopondereza kwambiri, malo osungunuka kwambiri, kusungunuka kwambiri, komanso kukhathamiritsa kwakung'ono kwamafuta ndi kutsika kwamafuta. Imadziwika kuti "space Age material" m'zaka za zana la 21.Magalasi opanda ma microspheres kukhala ndi zodziwikiratu zochepetsera kulemera ndi kutsekereza phokoso ndi kutenthetsa kwamafuta, kuti zinthuzo zikhale ndi ntchito yabwino yolimbana ndi kusweka ndi ntchito yokonzanso, ndipo zimagwiritsidwa ntchito kwambiri pazinthu zophatikizika monga pulasitiki yolimbitsa magalasi, marble ochita kupanga, agate yokumba, komanso mu mafakitale a petroleum, aerospace ndi azamlengalenga. , masitima atsopano othamanga kwambiri, magalimoto ndi zombo, zokutira zoziziritsa kukhosi ndi zinthu zina zalimbikitsa kwambiri chitukuko cha ntchito za sayansi ndi luso la dziko langa. Pofuna kukwaniritsa zofunikira za dielectric yochepa, kuchepa kochepa komanso kulemera kwa zipangizo zoyankhulirana za 5G, magalasi opanda kanthu a ma microspheres amathandizanso kwambiri chifukwa cha mtengo wawo wotsika komanso ntchito yabwino.

1 - Zosakaniza

Chemical kapangidwe ka dzenje galasi microspheres (misa chiŵerengero)

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

2- Zinthu

mtundu woyera

Ikhoza kugwiritsidwa ntchito kwambiri pazinthu zilizonse zomwe zili ndi zofunikira pa maonekedwe ndi mtundu.

3 - kachulukidwe kuwala

Kachulukidwe ka magalasi ocheperako ndi pafupifupi gawo limodzi mwa magawo khumi a kachulukidwe ka tinthu tating'ono ta magalasi. Pambuyo podzaza, kulemera kwake kwa chinthu kumatha kuchepetsedwa kwambiri, ma resin ochulukirapo amatha kusinthidwa ndikusungidwa, ndipo mtengo wazinthu ukhoza kuchepetsedwa.

4 - Lipophilicity

Magalasi opanda magalasi ang'onoang'ono ndi osavuta kunyowa ndikubalalitsa, ndipo amatha kudzazidwa ndi utomoni wambiri wa thermosetting thermoplastic, monga poliyesitala, epoxy resin, polyurethane, ndi zina zambiri.

5-Kukhala ndi ndalama zabwino

Popeza magalasi opanda kanthu a magalasi ndi timizere tating'onoting'ono, amakhala ndi madzi abwinoko mu utomoni wamadzimadzi kuposa ma flake, singano kapena osakhazikika, motero amakhala ndi ntchito yabwino yodzaza nkhungu. Chofunika kwambiri, tinthu tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono ta isotropic, kotero palibe choyipa cha mitengo yotsika yosagwirizana m'magawo osiyanasiyana chifukwa cha kuwongolera, zomwe zimatsimikizira kukhazikika kwazinthuzo ndipo sizingasunthike.

6- Kutentha ndi kutsekereza mawu

Mkati mwa magalasi ozungulira ma microspheres ndi mpweya wochepa kwambiri, kotero umakhala ndi mawonekedwe a kutsekemera kwa mawu ndi kutsekemera kwa kutentha, ndipo ndi chodzaza kwambiri chamitundu yosiyanasiyana ya kutentha ndi kutulutsa mawu. Zomwe zimatchingira magalasi opanda magalasi ang'onoang'ono zitha kugwiritsidwanso ntchito kuteteza zinthu kutenthedwa ndi kutentha komwe kumachitika chifukwa chakusinthana pakati pa kutentha kofulumira komanso kuzizira kofulumira. Kukana kwakukulu kwapadera komanso kuyamwa kwamadzi otsika kwambiri kumapangitsa kuti azigwiritsidwa ntchito kwambiri popanga zida zotchinjiriza chingwe.

7 - Kuchepetsa mafuta

Tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tambiri timene timayamwa mafuta. Panthawi yogwiritsira ntchito, kuchuluka kwa utomoni kumatha kuchepetsedwa kwambiri, ndipo kukhuthala sikungawonjezeke kwambiri ngakhale potengera kuchuluka kwakukulu kowonjezera, komwe kumathandizira kwambiri kupanga ndi magwiridwe antchito. Onjezani kupanga bwino ndi 10% mpaka 20%.

8- Low dielectric mosasinthasintha

Mtengo wa Dk wa magalasi opanda kanthu a galasi ndi 1.2 ~ 2.2 (100MHz), omwe amatha kusintha bwino mphamvu ya dielectric ya zinthuzo.

Mapulasitiki a mikanda yagalasi yopanda kanthu

(1) Pakuti kusinthidwa kwa mapulasitiki uinjiniya monga nayiloni, PP, PBT, PC, POM, etc., akhoza kusintha fluidity, kuthetsa galasi CHIKWANGWANI kukhudzana, kugonjetsa warpage, kusintha lawi retardant ntchito, kuchepetsa kumwa galasi CHIKWANGWANI, ndi kuchepetsa kupanga ndalama.

(2) Kudzaza ndi olimba PVC, PP, Pe, ndi kupanga profiled zipangizo, mipope ndi mbale kungachititse kuti katunduyo kukhazikika mulingo wabwinobwino, kupititsa patsogolo kuuma ndi kutentha kukana kutentha, kupititsa patsogolo mtengo wa katundu, kupititsa patsogolo ntchito zopangira ndi kuchepetsa ndalama.

(3) Kudzaza mu PVC, PE ndi zingwe zina ndi zida zotsekera m'chimake zimatha kupititsa patsogolo kutentha kwa mankhwala, kutchinjiriza, kukana kwa asidi ndi alkali ndi katundu wina ndi ntchito yopangira zinthu, kuonjezera zotuluka ndi kuchepetsa ndalama.

(4) Kudzaza mbale ya epoxy resin copper clad kungachepetse kukhuthala kwa utomoni, kuonjezera mphamvu yopindika, kukonza mawonekedwe ake akuthupi ndi makina, kuonjezera kutentha kwa galasi, kuchepetsa kusinthasintha kwa dielectric, kuchepetsa kuyamwa kwa madzi, ndi kuchepetsa mtengo. .

(5) Kudzaza ndi poliyesitala wosakanizidwa kumatha kuchepetsa kuchuluka kwa shrinkage ndi kutsuka kwa madzi a chinthucho, kumapangitsa kuti musamavalidwe komanso kuuma, komanso kukhala ndi zingwe zocheperako pakuyatsa ndi zokutira. Amagwiritsidwa ntchito pazinthu za FRP, mawilo opukutira, zida, ndi zina.

(6) Kudzaza ndi utomoni wa silicone kumatha kusintha mawonekedwe a thupi ndi makina, ndipo kudzaza kochuluka kumatha kuchepetsa kwambiri mtengo, womwe ndi chinthu choyenera kupanga nkhungu.
