1)Kushandiswa kukuru kwezvinhu zvekuvaka giredhi cellulose ether
Munda wezvivakwa zvekuvaka ndiyo inonyanya kudiwa munda wecellulose ether. Cellulose ether ine zvinhu zvakanakisa zvakadai sekukora, kuchengetedza mvura, uye kunonoka, saka inoshandiswa zvakanyanya kuvandudza nekugadzirisa dhaka rakasanganiswa (kusanganisira dhaka rakanyorova-yakasanganiswa uye yakaoma-yakasanganiswa dhaka), PVC resin kugadzira, latex pendi, putty, tile inonamira, Kuitwa kwezvivakwa zvekuvaka zvinosanganisira pasi pevhu rekudzivirira uye dhaka rekudzivirira rinoita kuti zvigadzirise zvigadzirwa zvechivako zvinosanganisira zvinopisa zvekudzivirira uye dhaka rekudzivirira. Kubudirira kwekuvaka kwezvivakwa nekushongedza, uye kunoshandiswa zvisina kunanga kune masonry plastering kuvaka uye mukati nekunze kushongedza kwemadziro emhando dzakasiyana dzezvirongwa zvekuvaka. Nekuda kwehukuru hwekudyara mumunda weinjiniya yekuvaka, marudzi akasiyana emapurojekiti ekuvaka akaparadzirwa, kune marudzi mazhinji, uye kufambira mberi kwekuvaka kunosiyana zvakanyanya, zvekuvaka giredhi cellulose ether ine hunhu hwehupamhi hwekushandisa, kudiwa kukuru kwemusika, uye vatengi vakapararira.
Pakati pemhando dzepakati uye dzepamusoro-soro dzekuvaka giredhi HPMC, giredhi rekuvaka HPMC ine tembiricha yegel ye75 ° C inonyanya kushandiswa muvhu rakaoma-rakasanganiswa uye mamwe minda. Iyo ine yakasimba yakakwirira tembiricha kuramba uye yakanaka application maitiro. Kushanda kwayo kwekushanda ndiyo tembiricha yegel Haikwanise kutsiviwa negiredhi rekuvaka HPMC pa60 ° C, uye vatengi vepamusoro-soro vane zvinodiwa zvakanyanya pakugadzikana kwemhando yerudzi urwu rwechigadzirwa. Panguva imwecheteyo, zvakaoma zvehunyanzvi kugadzira HPMC ine tembiricha yegel ye75°C. Huwandu hwekudyara hwemidziyo yekugadzira yakakura, uye chikumbaridzo chekupinda chakakwira. Mutengo wechigadzirwa wakakwira zvakanyanya kupfuura wegiredhi rekuvaka HPMC ine tembiricha yegel ye60 ° C.
Iyo yepamusoro-yekupedzisira PVC-yakananga HPMC chinhu chakakosha chekuwedzera pakugadzirwa kwePVC. Kunyangwe HPMC ichiwedzerwa muhushoma uye inoverengera yakaderera chikamu chePVC mutengo wekugadzira, chigadzirwa chekushandisa mhedzisiro yakanaka, saka mhando yayo inodiwa yakakwira. Vagadziri vashoma vekumba nekune dzimwe nyika veHPMC yePVC, uye mutengo wezvigadzirwa zvinobva kunze kwenyika wakakwira zvakanyanya kupfuura wezvigadzirwa zvemumba.
2)Kuvandudza Maitiro eKuvaka Material Giredhi Cellulose Ether Indasitiri
①Iko kusimukira kwakagadzikana kweindasitiri yekuvaka yenyika yangu inoenderera mberi nekufambisa kudiwa kwemusika wekuvaka giredhi cellulose ether.
Zvinoenderana nedata rakaburitswa neNational Bureau of Statistics, muna 2021, huwandu hwemaguta emunyika yangu (chikamu chehuwandu hwemaguta muhuwandu hwenyika) huchasvika 64.72%, kuwedzera kwe0.83 percent kana zvichienzaniswa nekupera kwa2020, uye kuwedzera kuchienzaniswa nehuwandu hwemadhorobha hwe49.95% in 49. yapinda pakati nepakati uye nhanho dzekupedzisira dzekugara kwemaguta. Zvichienderana, kukura kwekudiwa kwese mumusika wedzimba wezvivakwa kwakapindawo padanho rakagadzikana, uye kusiyanisa kwekudiwa mumaguta akasiyana kwave kuwedzera kuoneka. Kudiwa kwedzimba kuri kuramba kuchiwedzera. Mune ramangwana, nekudzikira kwechikamu cheindasitiri yekugadzira indasitiri uye nekuwedzera kwechikamu cheindasitiri yebasa, kuwedzera kwemafomu ebasa anochinjika senge hunyanzvi uye bhizinesi, uye kuvandudzwa kwemhando dzehofisi dzinochinjika, zvinodiwa zvitsva zvichaiswa pamberi pekutengeserana kwemadhorobha, nzvimbo yekugara uye chiyero chekugara-basa. Zvigadzirwa zvezvivakwa zvinodikanwa zveindasitiri zvichave zvakasiyana, uye indasitiri yezvivakwa yedzimba uye indasitiri yekuvaka yapinda munguva yekuchinja uye yekuchinja.
Huwandu hwekudyara hweindasitiri yekuvaka, nzvimbo yekuvaka yezvivakwa, nzvimbo yakapedzwa, nzvimbo yekushongedza dzimba uye shanduko dzayo, huwandu hwemari yevagari uye tsika dzekushongedza, nezvimwe, ndizvo zvinhu zvikuru zvinokanganisa kudiwa kwemusika wepamba wekuvaka zvinhu giredhi cellulose ether. Nzira yekukura kwemaguta yakabatana zvikuru. Kubva 2010 kusvika 2021, kupedzwa kwekudyara kwezvivakwa kwenyika yangu uye indasitiri yekuvaka inobuda kukosha kwakachengetedza tsika yakadzikama yekukura. Muna 2021, nyika yangu real estate development investment kupedzwa mari yaive 14.76 trillion yuan, gore-pa-gore kuwedzera kwe4.35%; indasitiri yekuvaka yakaburitsa kukosha kwe29.31 trillion yuan, kuwedzera kwe11.04% gore-pagore.
Kubva 2011 kusvika 2021, avhareji yegore rekukura kwekukura kwenzvimbo yekuvaka dzimba muindasitiri yekuvaka yemunyika yangu ndeye 6.77%, uye avhareji yegore rekukura kwekukura kwenzvimbo yekuvaka yekupedzwa kweimba ndeye 0.91%. Muna 2021, nzvimbo yekuvaka dzimba yeindasitiri yekuvaka yenyika yangu ichave 9.754 bhiriyoni square metres, ine gore-pa-gore kukura kwe5.20%; nzvimbo yekuvaka yakapedzwa ichave 1.014 bhiriyoni masikweya mita, ine gore-pa-gore kukura kwe11.20%. Iko kukura kwakanaka kweindastiri yekuvaka yedzimba kuchawedzera kushandiswa kwezvinhu zvekuvaka sedhaka rakasanganiswa, PVC resin kugadzira, latex pendi, putty, uye mataira anonamira, nekudaro kufambisa kudiwa kwemusika kwekuvaka giredhi cellulose ether.
②Nyika inoshingairira kusimudzira zvivakwa zvekuvaka zvakasvibirira zvinomiririrwa nedhaka yakasanganiswa, uye nzvimbo yekuvandudza yemusika yekuvaka giredhi cellulose ether inowedzera kuwedzerwa.
Dope chinhu chinosungirirwa chinoshandiswa pakuvaka zvidhinha. Inoumbwa nechimwe chikamu chejecha uye zvisungo zvekubatanidza (samende, lime paste, ivhu, nezvimwewo) nemvura. Nzira yechinyakare yekushandisa dhaka iri pa-saiti kusanganisa, asi nekufambira mberi kwetekinoroji yeindasitiri yekuvaka uye nekuvandudzwa kwezvinodiwa zvekuvaka, zvikanganiso zvepa-saiti yekusanganisa dhaka zvave kuwedzera mukurumbira, semhando isina kugadzikana, kuraswa kukuru kwezvinhu, imwe mhando yedhaka, yakaderera dhigirii yekuvaka yakabudirira uye kusvibisa nharaunda, nezvimwe.
Kuenzaniswa ne-on-saiti yekusanganisa dhaka, iyo yakagadzirira-yakasanganiswa dhaka inosanganisirwa yakasanganiswa, yakavharwa yekufambisa, pombi pombi yekufambisa, muchina kupfapfaidza pamadziro, uye maitiro ekuita kwekunyorova kusanganisa pachayo, iyo inoderedza zvakanyanya chizvarwa cheguruva uye yakanakira kuvaka mechan. Naizvozvo Ready-mixed dhaka ine zvakanakira kugadzikana kwemhando yakanaka, hupfumi hwakasiyana, hushamwari hwekuvaka nharaunda, kuchengetedza simba uye kuderedzwa kwekushandisa, uye ine yakanaka hupfumi uye nharaunda mabhenefiti. Kubva 2003, nyika yakaburitsa akatevedzana akakosha magwaro emutemo kusimudzira kugadzirwa uye kushandiswa kweakagadzirira-akasanganiswa dhaka uye kugadzirisa yakagadzirira-yakasanganiswa dhaka indasitiri chiyero.
Parizvino, kushandiswa kwedhaka rakagadzirwa-yakasanganiswa panzvimbo pe-saiti yakasanganiswa dhaka yave imwe yenzira dzakakosha dzekudzikisa kuburitswa kwePM2.5 muindasitiri yekuvaka. Mune ramangwana, nekuwedzera kushomeka kwejecha uye zviwanikwa zvevhu, mutengo wekushandisa zvakananga jecha panzvimbo yekuvaka uchawedzera, uye kuwedzera kwemitengo yebasa kuchaita kuti pave nekuwedzera zvishoma nezvishoma mumutengo wekushandiswa kweiyo-saiti yakasanganiswa dhaka, uye kudiwa kwedhaka rakagadzirwa-yakasanganiswa muindasitiri yekuvaka kucharamba kuchikura. Huwandu hwezvinhu zvekuvaka giredhi cellulose ether mudhaka rakagadzirwa-yakasanganiswa kazhinji hunoita 2/10,000. Kuwedzera cellulose ether kunobatsira kukobvuta yakagadzirira-yakasanganiswa dhaka, kuchengetedza mvura uye kunatsiridza mashandiro ekuvaka. Kuwedzera uku kuchafambisawo kukura kwekudiwa kwezvinhu zvekuvaka giredhi cellulose ether.
