Ke hoʻomau nei ka hoʻonui ʻana o nā mea quartz i hoʻohui ʻia i ka pūpū hoʻoheheʻe kālā ma nā ʻāina i kūkulu ʻia i kēlā me kēia makahiki, ʻoi aku ka nui o ka ʻike ma ka silica sol mold shell ma ka papa honua.E hoʻohālikelike me ke kumukūʻai a me ka hoʻohana ʻana i ka mea zirconium i hana i kahi holomua nui, He mea hoʻohana pono ʻenehana i kēia manawa.
Ua koho ʻia nā huahana quartz fused kiʻekiʻe kiʻekiʻe silica raw material [sio2>99%], hoʻoheheʻe ʻia i loko o ka umu ahi a i ʻole ka umu kūʻē, ma ke kiʻekiʻe o 1695-1720 ℃.Ma muli o ka viscosity kiʻekiʻe o ka sio2 hehee, ʻo ia ka 10 ^ 7 Pa · s ma 1900 ℃, ʻaʻole hiki ke hoʻoheheʻe ʻia e ke ʻano hoʻolei.Ma hope o ka hoʻoluʻu ʻana, he vitreous a hiki ke hoʻohana ʻia i mea maka no nā huahana i puhi ʻole ʻia.Hōʻike ʻia ka Fused silica e ke kūpaʻa haʻalulu wela maikaʻi, haʻahaʻa haʻahaʻa thermal conductivity, liʻiliʻi hoʻonui coefficient, kiʻekiʻe wela ke kū i nā huahana ceramic a me nā mea refractory.No laila, loaʻa iā ia kahi kūpaʻa wela kiʻekiʻe.No laila, i ke kaʻina hana o ka hoʻoheheʻe ʻia a me ka ninini ʻana i ka pūpū quartz i hoʻoheheʻe ʻia ma muli o ka wela wela, He mea kūpono ia i ka hoʻolilo ʻana i ka hoʻoheheʻe ʻana refractory, hiki ke hoʻohana ʻia e like me ka papa o ka ʻili a i ʻole ka papa hope.
Hoʻohana nui ʻia kā mākou Fused silica Products i ka hoʻolei pololei ʻana, quartz ceramic roller i ka ʻoihana aniani, refractory material, ceramic raw material, glass raw material, epoxy resin casting, electronic sealing material, uila kukui kumu, lāʻau lapaʻau, hoʻolei, a me nā ʻoihana ʻē aʻe o ka. nā kumu waiwai nui, a me ka pena, ka uhi a me nā ʻoihana kemika ʻē aʻe e hoʻopiha pono ai.
ʻO ka maʻiʻo o ka Sio2 maʻemaʻe no ka quartz fused: ʻaʻole e emi ka Sio2 o Fused silica A ma lalo o 99.95%, ʻaʻole emi ka helu B ma lalo o 99.8%, a ʻaʻole emi ka helu C ma mua o 99%
