Semusanganiswa wepamusoro-inoshanda, yekuvaka giredhi cellulose ether inogona kuvandudza kuchengetedza kwemvura uye kukora zvivakwa zvezvivakwa zvekuvaka, nekuvandudza kushanda kwekuvaka. Inoshandiswa zvakanyanya kuvandudza uye kukwirisa kusanganisira masonry dhaka, thermal insulation motar, tile bonding dhaka, Self-leveling dhaka, pamwe nekuita kwezvigadzirwa zvekuvaka zvinosanganisira PVC resin kugadzira, latex pendi, inodzivirira mvura putty, nezvimwewo, ita kuti isangane nezvinodiwa zvekuchengetedza simba uye kuchengetedza kwezvakatipoteredza, kunatsiridza kugona kwekuvaka kwekuvaka nekushongedza shandisa kune akasiyana marudzi ekuvaka uye kushongedzwa. Masonry uye plastering kuvaka, mukati nekunze kushongedza kwemadziro kunoenderana nekusimudzira kutungamira kweiyo nyika indasitiri mutemo pamusoro pekuchengetedza simba uye kuchengetedza kwezvakatipoteredza kwezvinhu zvitsva zvekuvaka. Iyo kambani yekuvaka zvinhu giredhi cellulose ether inonyanya kukwira-yekupedzisira chivakwa giredhi HPMC, uye minda yayo huru yekushandisa inosanganisira thermal insulation mortar, tile adhesive, self-leveling, Wallpaper glue uye mamwe akaoma-akasanganiswa dhaka minda, pamwe ne polyvinyl chloride (PVC), Electronic slurry nemimwe minda; kune zvakare zvimwe zvigadzirwa zvakajairwa, izvo zvinonyanya kushandiswa mudhaka-yakasanganiswa dhaka, yakajairwa dhaka uye madziro scraping putty.
Nekuda kwehukuru hwakakura hwekudyara mundima yeinjiniya yekuvaka, musika wakakura uye kudiwa kukuru, kudiwa kwemusika kwese kwezvivakwa giredhi cellulose ether kwakakura zvakanyanya kupfuura kudiwa kweselulosi ether mune mamwe minda. Inonyanya kushandiswa mune yakagadzirira-yakasanganiswa dhaka, bonding agent, PVC, putty, etc. Parizvino, kudiwa kwenyika yangu yekuvaka zvinhu-giredhi cellulose ether (kusanganisira kuvaka, PVC uye coatings) inodarika 90% yekudiwa kweiyo isiri-ionic cellulose ether.
Asi kubva pakuona kwepasi rose, inenge 52% ye-non-ionic cellulose ethers inoshandiswa mumunda wezvigadzirwa zvekuvaka, iyo iri kure pasi pezinga reimba. Chikonzero chikuru ndechekuti, kune rimwe divi, chiyero chekudyara mumunda weinjiniya yekuvaka munyika yangu yakakura uye ichikura. Kunyange zvazvo kukura kuri kuderera, vhoriyamu yakakura; Naizvozvo, nyika yangu yekuvaka zvinhu giredhi cellulose ether ine hunhu hwehupamhi hwemashandisirwo emhando, kudiwa kukuru kwemusika, uye vatengi vakapararira. Zvichienderana ne220,000 matani ezvivakwa-giredhi cellulose ether inodiwa pamusika wepamba muna 2018 uye mutengo weavhareji we25,000 yuan/tani, musika wekuvaka wemba-giredhi cellulose ether musika ungangoita 5.5 bhiriyoni yuan.
Nezve zvekuvaka giredhi isiri-ionic cellulose ether ine chekuita, pane maviri maitiro. Chekutanga pane zvese, zvinokanganiswa zvakanyanya nemaindasitiri epasi senge engineering yekuvaka, real estate nekushongedza. Mumakore achangopfuura, kunyangwe nyika yangu yekudyara zvivakwa uye nzvimbo yekuvaka yemabhizimusi ekuvandudza zvivakwa yakawedzera gore negore, mwero wekukura wakadzikira zvakanyanya. Saizvozvo, chiyero chekukura kwekugadzirwa kwenyika kwedhaka rakagadzirwa-musanganiswa uye machira kwakadzikira.
Chimwe chinhu ndechekuti mutemo unotungamira kuvandudzwa kwezvivakwa zvakasvibirira, zvinochengetedza simba uye zvine hushamwari kwezvakatipoteredza uye kuendesa kunze kwenyika kudiwa kwevatengi kuChina, izvo zvinogadzirisa kuderera kwekukura kwedzimba. Iyo "Yegumi Nematatu Yemakore Chirongwa cheKuvaka Kuchengetedza Kwesimba uye Green Building Development" inoisa mberi zvinangwa. Pakazosvika 2020, huwandu hwesimba rekushandisa kwezvivakwa zvitsva zvemudhorobha huchawedzera ne20% kana zvichienzaniswa ne2015; chikamu chenzvimbo yekuvaka yakasvibirira muzvivakwa zvitsva zvemudhorobha ichapfuura 50%, uye chikamu chezvakasvibirira zvekuvaka zvichashandiswa Kupfuura 40%; nzvimbo yekugadzirisa simba rekugadzirisa zvivako zvekugara zviripo zvinodarika mamiriyoni 500 square metres, uye kugadzirisa kwekuchengetedza simba kwezvivako zvevanhu mamiriyoni zana emamita. Chikamu chezvivakwa zvekuchengetedza simba muzvivako zvekugara zviripo mumaguta nemataundi munyika yose zvinodarika 60%. Kuvandudzwa kwe cellulose ether kunopa rubatsiro rwemitemo. Mushure medambudziko rechikwereti cheEurope muna 2012, vatengi mune dzimwe nyika vakawedzera kutenga kwavo cellulose ether kubva kuChina nedzimwe nyika dzichiri kusimukira kuitira kuti vagadzirise dambudziko uye kuderedza mitengo.
