Heat Insulation Yakaderera Mvura Yekunyura Hollow Glass Spheres
Hollow glass microspheres ine huremu hwakareruka, vhoriyamu hombe, yakaderera yekupisa conductivity, yakakwirira yekumanikidza simba, uye yakanaka fluidity. Iwo anoshandiswa kuve echigadzirwa mafirita uye ekuvhenekesa maajenti mune pendi coating, rabha, akagadziridzwa mapurasitiki, girazi fiber yakasimbiswa mapurasitiki, dombo rekugadzira, putty uye mamwe maindasitiri; Mune oiri uye gasi muminda migodhi maindasitiri, kuita kwavo kwakakwirira compression kuramba uye kuderera density kunogona kuburitsa yakakwirira-simba yakaderera-density simende slurry uye yakaderera-density drilling fluid.
Hollow girazi microspheres ihollow glass spheres ine madiki madiki, ayo ari inorganic isiri-metallic zvinhu. Iyo yakajairika particle saizi renji ndeye 28-120 microns, uye iyo yakawanda density ndeye 0.2-0.6 g/cm3. Iine zvakanakira uremu huremu, yakaderera thermal conductivity, kuvharidzira inzwi, kupararira kwepamusoro, kunaka kwemagetsi ekudzivirira uye kugadzikana kwekupisa. Icho chitsva chakagadziridzwa chakareruka zvinhu zvine huwandu hwakasiyana hwekushandisa uye kuita kwakanakisa.
1: Ruvara rwekutaridzika rwakachena chena. Inogona kushandiswa zvakanyanya mune chero zvigadzirwa zvine zvinodiwa pakuonekwa uye ruvara.
2: Chiedza chakananga giravhiti uye vhoriyamu hombe. Density ye hollow glass microspheres ingangoita chikamu chimwe mugumi chehuremu hwechinyakare mafirita particles. Mushure mekuzadza, inogona kuderedza zvakanyanya huremu hwechigadzirwa, kutsiva uye kuchengetedza mamwe marezeni ekugadzira, uye kuderedza mutengo wechigadzirwa.
3: Iine organically modified (lipophilic) pamusoro. Hollow girazi microspheres iri nyore kunyorova uye kuparadzira, uye inogona kuzadzwa mune yakawanda thermosetting thermoplastic resin, senge polyester, pp, pvc, epoxy, polyurethane, nezvimwe.
Hollow glass microspheres inopihwawo ine conductive coatings. Conductive coating ine optimized thickness inopa spherical particles ine yakanaka conductivity uye kudzivirira zvivakwa uku uchichengetedza huremu hwekuchengetedza huremu hwakabatana nehollow-core low-density zvinhu. Aya maconductive microbubbles akakodzera kushandiswa mune zvechiuto zvikumbiro, biotechnology, zvigadzirwa zvekurapa, zvemagetsi, uye mamwe maindasitiri ehunyanzvi.

Kunyanya kushandiswa kwegoro girazi microspheres:
1. Kugadziriswa kwenylon, PP, PBT, PC, POM, PVC, ABS, PS uye mamwe mapurasitiki anogona kuvandudza fluidity, kubvisa girazi fiber exposure, kukunda warpage, kunatsiridza flame retardant properties, kuderedza kushandiswa kwegirazi fiber, uye kuderedza mari yekugadzira.
2. Kuzadza yakaoma PVC, PP, PE, kugadzira profiles, mapaipi uye mapepa, zvinogona kuita kuti zvigadzirwa zvive zvakanaka dimensional kugadzikana, kuvandudza kuoma uye kupisa kwekushisa kwekushisa, kuvandudza kushandiswa kwemari yezvigadzirwa, kuvandudza kushanda kwekugadzira uye kuderedza mari.
3. Yakazadzwa muPVC, PE uye mamwe tambo uye insulating sheath zvinhu, inogona kuvandudza chigadzirwa chekushisa kwekushisa kwepamusoro, kuvhara, asidi uye alkali kuramba uye zvimwe zvinhu uye kushandiswa kwekugadzirwa kwechigadzirwa, kuwedzera kuburitsa uye kuderedza mari.
