Henan Sinmat Chemical Co., Ltd. ndi amodzi mwa opanga odalirika komanso ogulitsa amtundu wa gelisi ya silika ku China. Podziwa zambiri, tikukulandirani ndi manja awiri kuti mugule gel osakaniza a silika wogulitsidwa pano kuchokera kufakitale yathu. Lumikizanani nafe zitsanzo zaulere.
Mawu Oyamba
Gelisi yamtundu wa silica kapena silika gel A, ndi amorphous, yogwira kwambiri adsorbent material ndi yopapatiza pore kugawa kukula. Silika gel A ndi wabwino-pore silica gel, ndipo pang'ono pore kukula kwake ndi 2~3 nm. Mtundu A silika gel osakaniza amaonedwa kuti ndi zofunika za ochiritsira woyera kapena mandala silika gel osakaniza, komanso chizindikiro silika gels.
Gelisi ya silika yamtundu wa A imakhala ndi pore yaying'ono koma malo owoneka bwino kwambiri, zomwe zimapatsa mphamvu zotsatsa mamolekyu amadzi, makamaka m'malo achinyezi otsika pomwe amawonetsa bwino kwambiri hygroscopic.
Mtundu A silica gel ndiye chinthu chofunikira kwambiri pakati pa ma gels a silika a desiccant. Imakhala ndi mayamwidwe amphamvu a chinyontho komanso liwiro lowuma mwachangu, ndizomwe zimagwiritsidwa ntchito poyanika mpweya wamafakitale ndi mpweya woponderezedwa, motero ndi imodzi mwamitundu yomwe imagwiritsidwa ntchito kwambiri ya silika gel. Kuonjezera apo, mtundu wa A silica gel amagwiritsidwanso ntchito poletsa chinyezi ndi kusindikiza chakudya, mankhwala ndi zida zolondola, komanso ngati gawo laling'ono la mtundu-losonyeza silika, ndi zina zotero.
