Tempered girazi musika wekupa mamiriro uye kuendesa kunze uye kunze
Girazi rinodziya rinouya mumhando dzakawanda
Girazi rinodziya ndiro girazi rekuchengetedza.Girazi ine yakanaka kwazvo yekusapfeka uye yakaoma kwazvo, ine Vickers kuomarara kwe622 kusvika 701. Girazi rakanyoroveswa zvirokwazvo rudzi rwegirazi rakadzvanywa.Kuti uvandudze simba regirazi, kemikari kana nzira dzemuviri dzinowanzoshandiswa kuumba compressive stress pamusoro pegirazi.Kana girazi rinoiswa pasi pemasimba ekunze, rinotanga kubvisa kushushikana kwepamusoro, nekudaro kuvandudza kutakura-kuremerwa simba uye kuwedzera girazi rekudzivirira.Kudzvinyirirwa nemhepo, kutonhora nekupisa, kukanganisa, nezvimwewo. Nzira dzekuronga dzegirazi rakapfava dzinonyanya kusanganisira kupatsanurwa nechimiro, kupatsanurwa nemaitiro uye kupatsanurwa nedhigirii rekudzikamisa:
girazi rakadzikama
Yakarongedzerwa nechimiro (yakadzika yakadzikama girazi, curved tempered girazi, nezvimwewo)
Yakakamurwa nemaitiro (girazi rinopisa, girazi rine makemikari, nezvimwewo)
Yakarongedzerwa nedhigirii rekupisa (semi-hasha girazi, super-hasha girazi, nezvimwewo)
Supply-side reforms inodzikamisa goho kukura
Mumakore achangopfuura, nyika yakashinga kusimudzira kugadziridzwa kwechikamu cheindasitiri yegirazi.Tempered girazi iindasitiri yakakamurwa yegirazi uye yakaverengerwawo mune yekugovera-side reform.Panyaya yezvakabuda, zvichienderana nehuwandu kubva kuNational Bureau of Statistics, girazi rakadzikama renyika yangu rakaburitsa shanduko kubva muna 2014 kusvika 2020. Muna 2020, girazi renyika yangu rinopisa raive 533 miriyoni masikweya metres, gore negore kuwedzera kwe 1.40%.
Tichitarisa kubva kumamiriro ekunze egirazi rakapfava, nyika yangu yakapfava girazi rekutumira chiyero chakakwira zvakanyanya kupfuura chikero chekunze.Kubva 2015 kusvika 2020, nyika yangu yakanyoroveswa girazi kunze chiyero chakaratidza kushanduka kwekukura maitiro.Muna 2020, nyika yangu yakatengesa kunze kwenyika inokwana 2.161 miriyoni matani egirazi yakadziya, uye kukosha kwekunze kwakasvika US$2.22 bhiriyoni.
Kukura kwemutengo wemusika muna 2021 nekuda kwekushomeka kwezvinhu uye kudiwa kwevatengi
Kubva 2018 kusvika 2021, kutora 8mm yakadzama girazi semuenzaniso, mutengo wayo wemusika wakaratidza kushanduka kwekukura maitiro.Muhafu yekutanga ye2019, iyo yepakati-yepakati mutengo we8mm yakatsamwa girazi yakadonha.Chikonzero chikuru chaive chekuti vagadziri vakadzikisa mitengo yezvigadzirwa kuti vaderedze zvigadzirwa.Sezvo hukama pakati pekupa uye kudiwa kwakadzikira, mutengo wepakati we8mm girazi rakadzikama wakatangazve kukura muhafu yechipiri ya2019, uyezve mutengo wakaramba uri pa80-90 yuan.Muna 2021, nekuda kwekuderera kwekuverenga uye nekusimudzirwa kwechinyakare chekushandisa kwepamusoro mwaka, mutengo wegirazi rakadzikiswa wakaratidzazve kukura kwakakosha Zvinoenderana nemaitiro, kubva munaGunyana 2021, mutengo wepakati we8mm girazi rakawedzera kusvika pa96.42 yuan/square mita.
YAOTAI inyanzvi yekugadzira girazi uye mupi wemhinduro yegirazi inosanganisira huwandu hwegirazi rakapfava, girazi rakashongedzwa, girazi rinotaridza, girazi rinoyangarara, girazi, Gonhi negirazi rehwindo, girazi refenicha, girazi rakamisikidzwa, girazi rakavharwa, girazi rakadhindwa uye girazi rakaiswa.Nemamwe makore makumi maviri ekuvandudzwa, kune mitsara miviri yekugadzira girazi repateni, mitsetse miviri yegirazi rinoyangarara uye mutsetse mumwe wegirazi rekudzosera.zvigadzirwa zvedu 80% ngarava kuenda mhiri kwemakungwa, Zvese zvigadzirwa zvedu zvegirazi zvine hutongi hwemhando yepamusoro uye zvakanyatsorongedzerwa mune yakasimba matanda kesi, ita shuwa kuti unogamuchira yakanakisa mhando chengetedzo yegirazi nenguva.
