Semusanganiswa wepamusoro-soro, cellulose ether yemhando yekuvaka inogona kuvandudza kuchengetedza mvura uye hunhu hwekukora kwezvinhu zvekuvaka, uye kuvandudza kushanda kwekuvaka. Inoshandiswa zvakanyanya kuvandudza nekugadzirisa zvinosanganisira masonry mortar, thermal insulation mortar, tile bonding mortar, Self-leveling mortar, pamwe nekushanda kwezvigadzirwa zvekuvaka zvinosanganisira PVC resin manufacturing, latex pendi, water-resistant putty, nezvimwewo, inoita kuti isangane nezvinodiwa zvekuchengetedza simba nekuchengetedzwa kwezvakatipoteredza, kuvandudza kushanda kwekuvaka nekushongedza, uye kushanda zvisina kunanga kumhando dzakasiyana dzemapurojekiti ekuvaka. Kuvakwa kwematombo neplaster, kushongedzwa kwemadziro emukati nekunze zvinoenderana negwara rekusimudzira renyika yeindasitiri pamusoro pekuchengetedza simba nekuchengetedzwa kwezvakatipoteredza kwezvinhu zvitsva zvekuvaka. Cellulose ether yemhando yekuvaka yekambani inonyanya kuve yepamusoro-soro HPMC yezvinhu zvekuvaka, uye minda yayo mikuru yekushandisa inosanganisira thermal insulation mortar, tile adhesive, self-leveling, wallpaper glue nedzimwe minda yemortar yakasanganiswa yakaoma, pamwe nepolyvinyl chloride (PVC), Electronic slurry nedzimwe minda; kunewo zvimwe zvigadzirwa zvakajairika, zvinonyanya kushandiswa mudhaka rakasanganiswa, dhaka rakajairika uye putty yekukwesha madziro.
Nekuda kwehuwandu hwakawanda hwekudyara mari mumunda weinjiniya yekuvaka, huwandu hwakawanda hwemusika uye kudiwa kukuru, kudiwa kwese kwemusika kwe cellulose ether yemhando yekuvaka kwakakura kupfuura kudiwa kwe cellulose ether mune dzimwe nzvimbo. Inonyanya kushandiswa mumota yakasanganiswa, bonding agent, PVC, putty, nezvimwewo. Parizvino, kudiwa kwenyika yangu kwe cellulose ether yemhando yekuvaka (kusanganisira kuvaka, PVC uye coatings) kunodarika 90% yekudiwa kwe non-ionic cellulose ether.
Asi kubva pamaonero epasi rose, inenge 52% ye non-ionic cellulose ethers inoshandiswa mumunda wezvinhu zvekuvaka, izvo zviri pasi zvakanyanya pedanho remuno. Chikonzero chikuru ndechekuti, kune rumwe rutivi, huwandu hwekudyara mumunda weinjiniya yekuvaka munyika yangu hwakakura uye huri kukura. Kunyangwe kukura kuri kudzikira, huwandu hwacho hwakakura; Naizvozvo, cellulose ether yemhando yekuvaka yenyika yangu ine hunhu hwekushandiswa kwakasiyana-siyana, kudiwa kukuru kwemusika, uye vatengi vakapararira. Zvichienderana nematani 220,000 e cellulose ether yemhando yekuvaka inodiwa mumusika wemuno muna 2018 uye avhareji yemutengo we25,000 yuan/tani, saizi yemusika we cellulose ether yemhando yekuvaka yemuno inosvika mabhiriyoni 5.5 yuan.
Kana tichitaura nezve ether yemhando yekuvaka isina ionic cellulose, pane zvinhu zviviri. Chekutanga, inokanganiswa zvikuru nemaindasitiri ari pasi pemvura akadai seinjiniya yekuvaka, dzimba nekushongedzwa. Mumakore achangopfuura, kunyangwe mari yekudyara muzvivakwa nenzvimbo yekuvaka yemakambani ekuvandudza dzimba munyika yangu yakawedzera gore negore, kukura kwacho kwaderera zvakanyanya. Saizvozvo, kukura kwekugadzirwa kwenyika kwemortar yakasanganiswa uye coatings kwakadzikira.
Chimwe chinhu ndechekuti mutemo uyu unotungamira kuvandudzwa kwezvivakwa zvakasvibira, zvinochengetedza simba uye zvine hushamwari kune zvakatipoteredza uye kutamisirwa kwezvinodiwa nevatengi vekune dzimwe nyika kuChina, izvo zvinoderedza kuderera kwekukura kwezvivakwa zvemuno. "Chirongwa cheMakore Mashanu cheGumi neMatatu cheKuchengetedza Simba reKuvaka uye Kuvandudza Kuvaka Zvine Hunhu" chinopa zvinangwa. Panosvika gore ra2020, huwandu hwesimba remagetsi hwezvivakwa zvitsva zvemumaguta huchawedzera ne20% zvichienzaniswa negore ra2015; chikamu chenzvimbo yezvivakwa zvakasvibira muzvivakwa zvitsva zvemumaguta chichapfuura 50%, uye chikamu chezvinhu zvekuvaka zvakasvibira chichashandiswa Kupfuura 40%; nzvimbo yekugadzirisa zvivakwa zvekugara zviripo inodarika mamiriyoni mazana mashanu emamita emativi, uye kugadziriswa kwezvivakwa zveveruzhinji kunochengetedza simba inodarika mamiriyoni zana emamita emativi. Chikamu chezvivakwa zvinochengetedza simba muzvivakwa zvekugara zviripo mumaguta nemataundi munyika yose chinodarika 60%. Kuvandudzwa kwe cellulose ether kunopa rutsigiro rwemutemo. Mushure medambudziko rechikwereti muEurope muna 2012, vatengi mune dzimwe nyika vakawedzera kutenga kwavo cellulose ether kubva kuChina nedzimwe nyika dziri kusimukira kuitira kuti vagadzirise dambudziko iri uye kuderedza mitengo.
