1)Main application ye grade cellulose ether yekuvaka
Munda wezvinhu zvekuvaka ndiwo munda unonyanya kudiwa weether ye celluloseCellulose ether ine hunhu hwakanaka hwakadai sekukora, kuchengetedza mvura, uye kunonoka, saka inoshandiswa zvakanyanya kuvandudza nekugadzirisa dhaka rakasanganiswa (kusanganisira dhaka rakasanganiswa nemvura uye dhaka rakasanganiswa rakaoma), kugadzira resin yePVC, pendi yelatex, putty, kunamira mataira, Kushanda kwezvinhu zvekuvaka zvinosanganisira dhaka rekupisa kupisa nezvinhu zvepasi zvinoita kuti zvisangane nezvinodiwa zvekuchengetedza simba nekuchengetedzwa kwezvakatipoteredza, kunovandudza kushanda zvakanaka kwezvivakwa nekushongedza, uye kunoshandiswa zvisina kunanga pakuvaka masonry plastering uye kushongedzwa kwemadziro mukati nekunze kwemarudzi akasiyana emapurojekiti ekuvaka. Nekuda kwekudyara kukuru mumunda weinjiniya yekuvaka, mhando dzakasiyana dzemapurojekiti ekuvaka dzakapararira, kune mhando dzakawanda, uye kufambira mberi kwekuvaka kunosiyana zvikuru, cellulose ether yemhando yezvivakwa ine hunhu hwekushandiswa kwakasiyana-siyana, kudiwa kukuru kwemusika, uye vatengi vakapararira.
Pakati pemhando dzepakati nedzepamusoro dzeHPMC yemhando yekuvaka, HPMC yemhando yekuvaka ine tembiricha yegel ye75°C inonyanya kushandiswa mumadhaka akasanganiswa akaoma uye mamwe minda. Inodzivirira tembiricha yakanyanya uye inoshanda zvakanaka. Kushanda kwayo ndiko tembiricha yegel. Haigone kutsiviwa neHPMC yemhando yekuvaka pa60°C, uye vatengi vemhando yepamusoro vane zvinodiwa zvakanyanya pakugadzikana kwemhando iyi yechigadzirwa. Panguva imwe chete, zvakaoma kugadzira HPMC ine tembiricha yegel ye75°C. Chiyero chekudyara chemidziyo yekugadzira chakakura, uye chiyero chekupinda chakakwira. Mutengo wechigadzirwa wakakwira zvakanyanya kupfuura weHPMC yemhando yekuvaka ine tembiricha yegel ye60°C.
HPMC yepamusoro-soro yePVC chinhu chakakosha pakugadzirwa kwePVC. Kunyangwe HPMC ichiwedzerwa zvishoma uye ichiverengera chikamu chidiki chemari yekugadzira PVC, mhedzisiro yekushandisa chigadzirwa yakanaka, saka zvinodiwa zvemhando yepamusoro zvakakwirira. Kune vagadziri vashoma veHPMC vepamba nevekunze vePVC, uye mutengo wezvigadzirwa zvinotengeswa kunze kwenyika wakakwira zvakanyanya kupfuura wezvigadzirwa zvepamba.
2)Kufambira Mberi Kwekugadzirwa Kwezvinhu Zvekuvaka Cellulose Ether Industry
①Kubudirira kwakasimba kweindasitiri yekuvaka yenyika yangu kuri kuramba kuchikurudzira kudiwa kwemusika kwezvinhu zvekuvaka zvemhando yepamusoro cellulose ether.
Sekureva kwedata rakaburitswa neNational Bureau of Statistics, muna 2021, huwandu hwevanhu vari mumaguta munyika yangu (chikamu chevanhu vari mumaguta munyika) huchasvika 64.72%, kuwedzera kwe0.83% zvichienzaniswa nekupera kwa2020, uye kuwedzera kwehuwandu hwevanhu vari mumaguta hwe49.95% muna 2010. 14.77%, zvichiratidza kuti nyika yangu yapinda muchikamu chepakati nepakupedzisira chekukura kwemaguta. Saizvozvo, kukura kwehuwandu hwevanhu vari mumusika wezvivakwa zvemuno kwapindawo muchikamu chakagadzikana, uye kusiyana kwehuwandu hwevanhu vari mumaguta akasiyana kwave pachena. Kudiwa kwedzimba kuri kuramba kuchiwedzera. Mune ramangwana, nekudzikira kwehuwandu hwevanhu vari muindasitiri yekugadzira zvinhu munyika yangu uye kuwedzera kwehuwandu hwevanhu vari muindasitiri yebasa, kuwedzera kwemhando dzemabasa dzinochinjika dzakadai sekuvandudza nekuita mabhizinesi, uye kukura kwemamodheru emahofisi anochinjika, zvinodiwa zvitsva zvichaiswa pamberi pekutengeserana kwemaguta, nzvimbo dzekugara uye kuenzana kwenzvimbo dzebasa. Zvigadzirwa zvezvivakwa zvinodiwa neindasitiri zvichave zvakasiyana-siyana, uye indasitiri yezvivakwa yemuno neindasitiri yekuvaka zvapinda munguva yekuchinja uye yekuchinja.
Chiyero chekudyara mari muindasitiri yekuvaka, nzvimbo yekuvaka yezvivakwa, nzvimbo yakapedzwa, nzvimbo yekushongedza dzimba nekuchinja kwayo, huwandu hwemari yevagari uye maitiro ekushongedza, nezvimwewo, ndizvo zvinhu zvikuru zvinokanganisa kudiwa kwemusika wemuno wezvinhu zvekuvaka zvemhando ye cellulose ether. Maitiro ekukura kwemaguta ane hukama hwepedyo. Kubva muna 2010 kusvika 2021, kupedzwa kwekudyara mari muindasitiri yezvivakwa uye kukosha kwekugadzirwa kwezvinhu muindasitiri yekuvaka kwakaramba kuri kukura kwakasimba. Muna 2021, huwandu hwekudyara mari muindasitiri yezvivakwa munyika yangu hwaive 14.76 trillion yuan, kuwedzera kwegore negore kwe4.35%; huwandu hwese hwezvigadzirwa muindasitiri yekuvaka hwaive 29.31 trillion yuan, kuwedzera kwe11.04% gore negore.
Kubva muna 2011 kusvika 2021, avhareji yekukura kwenzvimbo yekuvaka dzimba pagore muindasitiri yekuvaka yenyika yangu i6.77%, uye avhareji yekukura kwenzvimbo yekuvaka kwegore negore i0.91%. Muna 2021, nzvimbo yekuvaka dzimba muindasitiri yekuvaka yenyika yangu ichava 9.754 bhiriyoni square metres, nekukura kwegore negore kwe5.20%; nzvimbo yekuvaka yakapedzwa ichava 1.014 bhiriyoni square metres, nekukura kwegore negore kwe11.20%. Kukura kwakanaka kweindasitiri yekuvaka yemuno kuchawedzera kushandiswa kwezvinhu zvekuvaka zvakaita semota yakasanganiswa, kugadzira resin yePVC, pendi yelatex, putty, uye tile adhesive, nokudaro zvichikonzera kudiwa kwemusika kwe cellulose ether yezvinhu zvekuvaka.
②Nyika inosimudzira zvinhu zvekuvaka zvakasvibirira zvinomiririrwa nedhaka rakasanganiswa, uye nzvimbo yekuvandudza musika wezvinhu zvekuvaka zvegiredhi cellulose ether iri kuwedzerwa zvakanyanya.
Dura chinhu chinoshandiswa pakuvaka zvidhinha. Chinoumbwa nejecha nezvinhu zvinobatanidza (simende, lime paste, ivhu, nezvimwewo) nemvura. Nzira yechinyakare yekushandisa dura kusanganisa panzvimbo, asi nekufambira mberi kwetekinoroji muindasitiri yekuvaka uye kuvandudzwa kwezvinodiwa pakuvaka zvine hungwaru, zvikanganiso zvedura rekusanganisa panzvimbo zvave zvichinyanya kuoneka, zvakaita semhando isina kugadzikana, marara akawanda emidziyo, rudzi rumwe chete rwedura, kuvakwa kwakaderera uye kusvibisa nharaunda, nezvimwewo.
Kana tichienzanisa nedhaka rekusanganisa panzvimbo, maitiro edhaka rakasanganiswa anosanganisira kusanganisa kwakasimba, kutakurwa kwakavharwa, kutakurwa kwepombi dzepombi, kupfapfaidza nemuchina pamadziro, uye maitiro ekuita kwekusanganisa kwakanyorova, izvo zvinoderedza zvikuru kugadzirwa kweguruva uye zviri nyore kuvaka nemashini. Saka dhaka rakasanganiswa rine zvakanakira kugadzikana kwemhando yepamusoro, mhando dzakasiyana-siyana, nharaunda yekuvaka ine hushamwari, kuchengetedza simba uye kuderedza kushandiswa, uye rine mabhenefiti akanaka ehupfumi nenharaunda. Kubva muna 2003, nyika yakaburitsa magwaro akakosha ekusimudzira kugadzirwa nekushandiswa kwedhaka rakasanganiswa uye kuvandudza mwero weindasitiri yedhaka rakasanganiswa.
Parizvino, kushandiswa kwesimbi yakasanganiswa yakagadzirwa pachinzvimbo chesimbi yakasanganiswa panzvimbo kwave imwe yenzira dzakakosha dzekuderedza kuburitswa kwePM2.5 muindasitiri yekuvaka. Mune ramangwana, nekushaikwa kwejecha nematombo, mutengo wekushandisa jecha zvakananga panzvimbo yekuvaka uchawedzera, uye kuwedzera kwemari yevashandi kuchaita kuti mutengo wekushandisa simbi yakasanganiswa yakagadzirwa panzvimbo uwedzere zvishoma nezvishoma, uye kudiwa kwesimbi yakasanganiswa yakagadzirwa kare muindasitiri yekuvaka kucharamba kuchikura. Huwandu hwesimbi yemhando ye cellulose ether musimbi yakasanganiswa yakagadzirwa kare hunowanzoita 2/10,000. Kuwedzera cellulose ether kunobatsira kukora simbi yakasanganiswa yakagadzirwa kare, kuchengetedza mvura uye kuvandudza mashandiro ekuvaka. Kuwedzera uku kuchasimudzirawo kukura kwekudiwa kwesimbi yemhando ye cellulose ether.
