Girazi se silicate inorganic zvinhu, kuita kwakadzikama, uye yakatsetseka yakajeka, kunyanya yakakodzera kurongedza uye kuchengetedza zvinodhaka. Panguva imwecheteyo, maererano nezvimwe zvinhu, mutengo wegirazi hauna kudhura. Mumakore achangopfuura, nekukurumidza kukura kweindasitiri yemishonga, indasitiri yegirazi yekurapa munyika yedu uye chigadzirwa chakawana kukurumidza kusimudzira nekuvandudza, chave chinhu chikuru chekurongedza mumunda wemishonga yekurongedza, girazi rekurongedza zvinhu rinoshandiswa zvakanyanya mujekiseni, jekiseni rehupfu, iyo lyophilizer, zvigadzirwa zvebiological, zvigadzirwa zveropa, mvura yemumuromo, zvigadzirwa zvehutano, senge mabhodhoro egirazi anoshandiswa zvakanyanya mumhando dzakasiyana dzemishonga yekurongedza.
Magirazi ekuChina ekurongedza tekinoroji zvinyorwa zvichave zvakasiyana-siyana zvegirazi muzvikamu gumi nerimwe, maererano nekugadzira kwayo kugadzirwa kweinjiniya ndeyegirazi rebhodhoro, asi zvinoenderana nekuita kwayo uye kushandiswa kunofanirwa kunge kuri kwegirazi rezviridzwa. Bhodhoro regirazi chinwiwa chekurongedza chigadziko muChina, girazi zvakare inhoroondo yekurongedza zvinhu. Nekuwanda kwemhando dzakawanda dzezvinhu zvekurongedza mumusika, chigadziko chegirazi chichiri nechinzvimbo chakakosha mukuputira chinwiwa, icho chisingaparadzaniswe kubva pakurongedzerwa kwayo hunhu husingagone kutsiviwa nezvimwe zvekurongedza. Sezvo mushonga chinhu chakakosha, marudzi ese emishonga egirazi zvigadzirwa zvinoshandiswa semidziyo yekurongedzera zvine makemikari ari nani ekuumbwa, kuita uye zvemhando zvinodiwa pane akajairwa mabhodhoro egirazi. Yakaderera borosilicate girazi midziyo yagara iri iyo huru yekurongedza jekiseni muChina. Nekudaro, kuzadza asidhi uye alkali mvura ine yakaderera borosilicate girazi mugaba ine yakaderera mvura yekudzivirira nhanho iri nyore kutungamira kune inooneka miviri yekunze senge kupepeta uye mavara machena munguva inoshanda. Sechikamu chakakosha chemushonga, zvinhu zvekurongedza zvemishonga zvine hukama zvakanyanya nekuvandudzwa kweindasitiri yemishonga.
Hunhu hunorema uye husina kusimba hwemabhodhoro hwakakonzera kupararira kwemusika kupokana kumabhodhoro egirazi emishonga. Asi nekufamba kwemakore, nepurasitiki (chimiro: synthetic resin, plasticizer, stabilizer, pigment) mabhodhoro eAA phenol, plastiki plasticizer, mabhodhoro egirazi emishonga kubva kumashure kuenda kumusika chinzvimbo, girazi remishonga rine zvinotevera zvinokwikwidza zvakanakira: ine yakanaka kugadzikana kwemakemikari. , kwete nekuda kwekukwira kwekushisa, kusunungura zvinhu zvine chepfu, uye kusvibiswa mukati mebhodhoro rakapfeka; Mabhodhoro egirazi ekuomarara kwakanyanya, kwete nekuda kweiyo extrusion deformation, zvikasadaro mudziyo haugone kudzivirira extrusion; Kushandiswa kwegirazi mabhodhoro ane zvinodhaka, vatengi vanonyanya kuvimbiswa, mabhodhoro egirazi zviuru zvemakore ezvakaitika kare, kuchengetedzwa kwayo kwave kuchizivikanwa zvikuru, ine zvigadzirwa zvakachengeteka, uye zviri nyore kuuraya utachiona; Chimiro chinogona kuchinjika, chiri nyore kushongedza, zvigadzirwa zvekupfeka zvinoratidza giredhi repamusoro, kusimudzira kutengesa.
