Sezvatinoziva tese, zvishandiso zvitsva zvakanyorwa seimwe yenzira huru ye "yakagadzirwa muChina 2025" chirongwa.Seyakakosha sub munda, girazi fiber iri kuwedzera nekukurumidza.
Girazi fiber yakazvarwa muma1930s.Iyo inorganic isiri-metallic zvinhu inogadzirwa kubva kune main mineral raw materials senge pyrophyllite, quartz jecha, limestone uye kemikari mbishi zvinhu zvakaita seboric acid nesoda ash.Iine nhevedzano yezvakanakira senge mutengo wakaderera, uremu huremu, kusimba kwepamusoro, kupisa kwekushisa kwepamusoro uye kushorwa kwekuora.Simba rayo chairo rinosvika 833mpa/gcm3, inova yechipiri chete kune kabhoni fiber (inopfuura 1800mpa/gcm3) pakati pezvinhu zvakajairika.Icho chinhu chakanakisa chinoshanda uye chakarongeka zvinhu.
Musika wemumba unopa nguva yekuwedzera
Zvichienderana nenhoroondo yenhoroondo, masangano akakodzera akaverenga kuti avhareji yekukura kwegirazi fiber indasitiri inowanzo 1.5-2 nguva yekukura kweGDP yenyika.Owens Corning akaona kuti kukura kwepasi rose girazi faibha inodiwa ingangoita 1.6 nguva iyo yekugadzirwa kwemaindasitiri nekutarisa kumashure kune data renyika kubva 1981 kusvika 2015. Mhedzisiro yekuverenga yeHuatai Securities inoratidza kuti kubva 2006 kusvika 2019, chiyero chekukura. yepasi rose girazi fiber inoda ine hukama hwakanaka hwemutsara nekukura-pa-gore kukura kweGDP uye maindasitiri akawedzera kukosha.Pakati pavo, chiyero chekukura kwepasi rose girazi faibha chinodiwa chingangoita 1.81 nguva iyo yeGDP uye 1.70 nguva iyo yeindasitiri yakawedzera kukosha.Nekudaro, nhoroondo yenhoroondo inoratidza kuti munguva yakapfuura, hukama hwemutsara pakati pemumba girazi faibha kudiwa uye macroeconomic zviratidzo zvaive zvisina kusimba.Mumakore achangopfuura, chiyero chegirasi fiber inoda kukura kusvika pakukura kweGDP yakakwira zvakanyanya kupfuura iyo yenyika.Muna 2018 na2019, chiyero chaive 2.4 uye 3.0 zvakateerana.
Kutsvaga kudzokera kune kwakabva, izvi zvine hukama zvakananga kune yakaderera yekupinda mwero wegirazi fiber muChina.
Kushandiswa kwepagore neChina kwemunhu wega wega wegirazi faibha kwakadzikira zvikuru kupfuura kwenyika dzakabudirira.Muna 2019, China yakashandiswa pamunhu wegirazi fiber yaive ingangoita 2.8kg, nepo iyo yeUnited States, Japan, European Union nedzimwe nyika dzakabudirira dzaive 4.5kg.
Nzvimbo nhatu dzepamusoro dzefiberglass application muChina kuvaka, zvemagetsi nemidziyo, uye zvekufambisa, zvinoverengera 34%, 21%, uye 16% zvakateerana.
Pakati pavo, iyo yakakura kushandiswa kwekutungamira kwegirazi faibha mumunda wemagetsi nemidziyo yemagetsi jira remagetsi rinoshandiswa kugadzira copper clad laminate (CCL) mune yakadhindwa redunhu (PCB), iyo inodya yakawanda yemagetsi shinda (inenge 95%).Dzemukati meshinda yemagetsi iri kutsiviwa nezvigadzirwa zvemumba, uye huwandu hwezvinhu zvinotengeswa kunze kwenyika muChina tambo dzemagetsi dzakadzikira gore negore, uye zvimwe zvigadzirwa zvemhando yepamusoro zvinotsiviwa zvishoma nezvishoma nezvinounzwa kunze kwenyika.
Nekuenderera mberi kwekusimudzira kwe5g kushandiswa kwekutengesa, kudiwa kwePCB kwakawedzera zvakanyanya.Kuvakwa kwakakura-kwenzvimbo dzedata uye kudiwa kukuru kwemaseva kuchave simba guru rekutyaira rinotyaira nzvimbo yekukura yePCB musika munguva pfupi.Zvisina Driver uye AI zvikumbiro zvinopa tsigiro yekuda kwenguva refu yePCB, uye iyo yemagetsi munda ingangounza musika wekuwedzera wegirazi fiber mune ramangwana.
Mafambiro esimba repasi rose uye mitemo yezvakatipoteredza inoita kuti traffic ine huremu ive nyaya yenguva refu muindasitiri.Kushandiswa kwezvinhu zvisingaremi segirazi fiber reinforced composites ndiyo imwe yenzira huru, asi pane mukaha mukuru pakati peChina nedanho rinotungamira pasirese.Germany, United States neJapan pari zvino inyika dzine huwandu hwakati wandei hwezvinhu zvemotokari zvireruke.Pakati pavo, kushandiswa kwemotokari lightweight zvinhu muGermany kunoda kusvika 25%, iyo ndiyo yepamusoro-soro pasi rose.Pane mukaha mukuru pakati pekushandiswa kwezvinhu zvisingaremi mumotokari dzeChinese uye mazinga epamusoro ekunze.Semuenzaniso, kushandiswa kwealuminium nesimbi kunenge hafu yezinga repasi rose, uye kushandiswa kwemagnesium alloy kunenge 1/10 yeEuropean advanced level, kudiwa kweChina kwemotokari yegirazi fiber ichiri nenzvimbo huru yekukura.
Zvinoenderana nedata reChina fiber composites network, muna 2021, kubuda kwenyika kwegirazi faibha kwakasvika 6.24 miriyoni matani, zvichienzaniswa ne258000 matani muna 2001, uye CAGR yeChina yegirazi fiber indasitiri mumakore makumi maviri apfuura yaive yakakwira kusvika 17.3% .Kubva pakuona kwekuunza uye kutumira kunze data, iyo yenyika yekunze vhoriyamu yegirazi fiber uye zvigadzirwa muna 2021 yaive 1.683 miriyoni matani, nekuwedzera kwegore negore kwe26.5%;Hurukuro yekupinza yaive 182000 matani, kuchengetedza yakajairika.
