Kwenguva yakareba, zvinhu zvinoshandiswa pakuvaka madziro zvichiri lime yechinyakare. Lime inotsva inofanira kupfuura nepakati penzira yekuputira mvura, kupfapfaidza, uye kukwegura, uye wobva wawedzera zvinhu zvakaita semapanga ehemp kuti zvisanganiswe zvakaenzana usati wavaka. Maitiro ayo akasiyana-siyana, anodhura zvakanyanya, haana simba rakawanda, anodzikira zvakanyanya, anotya mvura, uye madziro anogona kutsemuka, kuputsika, kupwanyika, kudonha nezvimwe zvikanganiso. HCMilling (Guilin Hongcheng), semugadziri wemichina yekugadzira upfu hwakagadzirwa Pazvinhu zvekuvaka, ichatanga nzira yekugadzira upfu huchena hwakasanganiswa hwezvinhu zvekuvaka ne limestone sechinhu chikuru chisina kubikwa, mutengo wakaderera, simba rakawanda uye kugona kupinza hunyoro zvakanaka.

Lime yakagadzirwa negypsum putty yakagadzirwa mumakore achangopfuura inogona kushandiswa pasina kuwedzera zvinhu zvefiber, asi yekutanga inogadzirwa nekuwedzera gypsum yakaenzana, ine mutengo wakakwira kupfuura lime yechinyakare, uye madziro achiri kutsemuka. Yekupedzisira inogadzirwa nekuwedzera zvimwe zvinhu mu gypsum powder, ine mutengo wakakwira, uye inogona kushandiswa muzvivakwa zvepamusoro, izvo zvisina kukodzera zvivakwa zvakajairika nedzimba dzevanhu. Nzira yekugadzira upfu hwekuvaka hwakasanganiswa? Li Yinghai naLi Jing vakaburitsa nzira yekugadzira upfu huchena hwakasanganiswa hwekuvaka, hunotora limestone sezvinhu zvikuru, hunowedzera huwandu hwakati hwe gangue yemarasha, kana musanganiswa we silica, aluminium trioxide nemarasha, uye hunotumirwa mu shaft oven kuti hunyungudutswe kwemaawa 72-120 patembiricha ye1100-1200℃, inova chinhu chakakura, uye wobva wawedzera huwandu hwakakodzera hwe gypsum powder ku clinker, inova chigadzirwa chakapedzwa mushure mekukuya. Zvinhu zvayo zvinobva kwakasiyana-siyana. Gangue yemarasha inogona kushandiswa kushandura marara kuita pfuma, uye fomura yayo yakasiyana. Chigadzirwa ichi chine mashandiro maviri e lime yechinyakare nesimende. Ine simba rayo guru, inoshanda zvakanaka pakupinza mvura uye inodhura zvishoma. Haifanirwe kusanganiswa nezvinhu zvakaita semapanga ehemp. Inogona kupurastwa nekusanganisa nemvura zvakananga. Ine kunamatira kwakasimba, haina mabhuru kana mitswe pamadziro, uye inogona zvakare kushandiswa nekuwedzera pigment yekupenda. Ichinhu chitsva chekuvaka chinotsiva lime yechinyakare.

Nzira dziri pamusoro apa dzinoiswa muchoto chakamira, uye chigadzirwa chakapedzwa chinogona kugadzirwa nekukuya limestone kusvika pa 170-180 meshes neyakatwasukachinotendererachigayo. Kufamba kwemaitiro acho kuri nyore, izvo zvinobatsira kugadzirwa kwemichina yakawanda. HCMilling (Guilin Hongcheng), semugadziri wemidziyo yekugadzira hupfu hwezvinhu zvekuvaka, yagara ichishandisa zvakanyanya chigayo cheRaymond chine limestone, dombo remabwechigayo chinotenderera chakamirauye mimwe michina yekugadzira upfu hwezvinhu zvekuvaka mumapurojekiti ekugadzira upfu hwekuvaka. Kukora kwekugadzirisa kunogadziriswa pakati pe80-600 meshes. Pakugadzira upfu hwekuvaka, ine zvakanakira zvekubuda kukuru, kurongeka kuri nyore nezvimwewo. Kana muine zvinodiwa zvekutenga zvakakodzera, ndapota taurai nesu kuti muwane rumwe ruzivo nezvemidziyo uye mutipe ruzivo rwekutevera:

Zita rezvinhu zvisina kugadzirwa
