Mamiriro echeni yeindasitiri:
(1) Indasitiri yepamusoro
Zvinhu zvikuru zvinodiwa pakugadziraether ye cellulosezvinosanganisira donje rakanatswa (kana kuti pulp yehuni) uye zvimwe zvinonyungudutsa zvemakemikari zvakajairika, zvakaita sepropylene oxide, methyl chloride, liquid caustic soda, caustic soda, ethylene oxide, toluene nezvimwe zvinhu zvinobatsira. Makambani eindasitiri yepamusoro eindasitiri iyi anosanganisira donje rakanatswa, makambani ekugadzira pulp yehuni uye mamwe makambani emakemikari. Kuchinja-chinja kwemitengo yezvinhu zvikuru zvataurwa pamusoro apa kuchava nemhedzisiro yakasiyana pamutengo wekugadzira uye mutengo wekutengesa we cellulose ether.
Mutengo wedonje rakanatswa wakakwira. Tichitora ether yemhando ye cellulose semuenzaniso, munguva yekunyora, mutengo wedonje rakanatswa waive 31.74%, 28.50%, 26.59% uye 26.90% yemari yekutengesa ye cellulose ether yezvinhu zvekuvaka. Kuchinja-chinja kwemitengo yedonje rakanatswa kuchakanganisa mutengo wekugadzirwa kwe cellulose ether. Chinhu chikuru chekugadzira donje rakanatswa i cotton linters. Cotton linters ndeimwe yezvigadzirwa zvekugadzira donje, zvinonyanya kushandiswa kugadzira donje pulp, donje rakanatswa, nitrocellulose nezvimwe zvigadzirwa. Kukosha kwekushandiswa uye kushandiswa kwe cotton linters ne donje zvakasiyana zvikuru, uye mutengo wayo wakaderera pane we donje, asi une hukama hwakati nekuchinja-chinja kwemitengo ye donje. Kuchinja-chinja kwemutengo we cotton linters kunokanganisa mutengo we cotton rakanatswa.
Kuchinja-chinja kukuru kwemutengo wedonje rakanatswa kuchava nemhedzisiro yakasiyana pakutonga kwemitengo yekugadzira, mitengo yezvigadzirwa uye purofiti yemabhizinesi ari muindasitiri iyi. Kana mutengo wedonje rakanatswa wakakwira uye mutengo wedonje rehuni wakachipa, kuitira kuderedza mitengo, donje rehuni rinogona kushandiswa sechinotsiva uye chinowedzera donje rakanatswa, rinonyanya kushandiswa kugadzira maether e-cellulose ane viscosity yakaderera senge maether e-pharmaceutical uye e-cellulose grade grade. Sekureva kwedata kubva kuwebhusaiti yeNational Bureau of Statistics, muna 2013, nzvimbo yekudyara donje yenyika yangu yaive mahekita mamiriyoni 4.35, uye gonje renyika raive matani mamiriyoni 6.31. Sekureva kwenhamba kubva kuChina Cellulose Industry Association, muna 2014, gonje rehuni rakanatswa rakagadzirwa nevagadziri vedonje vakanatswa vepamba raive matani zviuru mazana matatu nemakumi matatu nemaviri, uye kuwanikwa kwezvinhu zvakagadzirwa kwakawanda.
Zvinhu zvikuru zvekugadzira michina yemakemikari yegraphite isimbi negrafiti kabhoni. Mutengo wesimbi negrafiti kabhoni unoratidza chikamu chakakwira chemutengo wekugadzira michina yemakemikari yegraphite. Kuchinja-chinja kwemitengo yezvinhu izvi kuchakanganisa mutengo wekugadzira uye mutengo wekutengesa michina yemakemikari yegraphite.
(2) Indasitiri ye cellulose ether iri pasi
Se "industrial monosodium glutamate", cellulose ether ine chikamu chidiki che cellulose ether uye ine mashandisirwo akasiyana-siyana. Maindasitiri ari pasi pemvura akapararira munzvimbo dzakasiyana-siyana dzehupenyu muhupfumi hwenyika.
Kazhinji, indasitiri yekuvaka iri pasi uye indasitiri yezvivakwa ine simba guru pakukura kwekudiwa kwe ether yemhando ye cellulose. Kana indasitiri yekuvaka yemuno neindasitiri yezvivakwa iri kukura nekukurumidza, kudiwa kwe ether yemhando ye cellulose yemhando yezvivakwa pamusika wemuno kuri kukura nekukurumidza. Kana kukura kweindasitiri yekuvaka yemuno neindasitiri yezvivakwa kuchiderera, kukura kwekudiwa kwe ether yemhando ye cellulose yemhando yezvivakwa pamusika wemuno kuchaderera, izvo zvichawedzera kukwikwidza muindasitiri iyi uye kukurumidzisa maitiro ekurarama kwemakambani akasimba muindasitiri iyi.
Kubva muna 2012, maererano nekuderera kweindasitiri yekuvaka yemuno neindasitiri yezvivakwa, kudiwa kwe cellulose ether yemhando yezvivakwa mumusika wemuno hakuna kuchinja zvakanyanya. Zvikonzero zvikuru ndeizvi: 1. Huwandu hwese hweindasitiri yekuvaka yemuno neindasitiri yezvivakwa hwakakura, uye kudiwa kwese kwemusika kwakakura; musika mukuru wevatengi we cellulose ether yemhando yezvivakwa uri kuwedzera zvishoma nezvishoma kubva munzvimbo dzakabudirira mune zvehupfumi uye maguta ekutanga neechipiri kusvika kumatunhu epakati nekumadokero nemaguta echitatu, mukana wekukura kwezvinodiwa zvemuno uye kuwedzera nzvimbo; 2. Huwandu hwe cellulose ether yakawedzerwa hunoita kuti pave nechikamu chidiki chemutengo wezvinhu zvekuvaka. Huwandu hunoshandiswa nemutengi mumwe chete hudiki, uye vatengi vakapararira, izvo zvinowanzo da kudiwa kwakasimba. Kudiwa kwese mumusika wepasi kwakagadzikana; 3. Kuchinja kwemutengo wemusika chinhu chakakosha chinokanganisa shanduko yechimiro chekudiwa kwe cellulose ether yemhando yezvivakwa. Kubva mugore ra2012, mutengo wekutengesa we cellulose ether yezvinhu zvekuvaka wakadzikira zvakanyanya, izvo zvakakonzera kudzikira kukuru kwemutengo wezvigadzirwa zvepakati kusvika zvepamusoro, zvichikwezva vatengi vakawanda kuti vatenge uye vasarudze, zvichiwedzera kudiwa kwezvigadzirwa zvepakati kusvika zvepamusoro, uye zvichideredza kudiwa kwemusika nenzvimbo yemitengo yemamodheru akajairwa.
Kukura kweindasitiri yemishonga pamwe nekukura kweindasitiri yemishonga zvichakanganisa kudiwa kwemishonga yemhando ye cellulose ether. Kuvandudzwa kwemararamiro evanhu pamwe neindasitiri yezvekudya yakabudirira zvinobatsira kusimudzira kudiwa kwemusika kwemakemikari emhando ye cellulose ether.
Kukura kwe cellulose ether
Nekuda kwekusiyana kwemaumbirwo ekudiwa kwe cellulose ether pamusika, makambani ane simba rakasiyana uye kusasimba anogona kugara pamwe chete. Tichifunga nezvekusiyana kuri pachena kwemaumbirwo ekudiwa kwemusika, vagadziri ve cellulose ether vepamba vakatora nzira dzakasiyana dzemakwikwi zvichibva pasimba ravo, uye panguva imwe chete, vanofanirwa kunzwisisa mafambiro ekukura uye gwara remusika zvakanaka.
(1) Kuve nechokwadi chekuti mhando yechigadzirwa chakasimba kucharamba kuri chinhu chikuru chinokwikwidza mumakambani e ether e cellulose.
Cellulose ether ndiyo inonyanya kukosha pamari yekugadzira yemakambani mazhinji ari pasi peindasitiri iyi, asi ine simba guru pamhando yezvigadzirwa. Mapoka evatengi vepakati nepamusoro anofanira kuedza fomura vasati vashandisa imwe mhando ye cellulose ether. Mushure mekugadzira fomura yakagadzikana, hazviwanzo kuve nyore kutsiva mamwe marudzi ezvigadzirwa, uye panguva imwe chete, zvinodiwa zvakanyanya zvinoiswa pakugadzikana kwemhando ye cellulose ether. Chiitiko ichi chinonyanya kuzivikanwa muminda yepamusoro-soro yakadai sevagadziri vezvinhu zvekuvaka zvikuru kumba nekune dzimwe nyika, zvinhu zvinobatsira pamishonga, zvinowedzera chikafu, uye PVC. Kuti vawedzere kukwikwidzana kwezvigadzirwa, vagadziri vanofanirwa kuona kuti mhando nekugadzikana kwemhando dzakasiyana dze cellulose ether dzavanopa zvinogona kuchengetedzwa kwenguva yakareba, kuitira kuti vagadzire mukurumbira uri nani pamusika.
(2) Kuvandudza mwero wekushandiswa kwetekinoroji yechigadzirwa ndiko kutungamirirwa kwemakambani emumba e-cellulose ether.
Nekukura kuri kuita tekinoroji yekugadzira yeether ye cellulose, nhanho yepamusoro yetekinoroji yekushandisa inobatsira mukuvandudza makwikwi akazara emabhizinesi uye kuumbwa kwehukama hwakasimba nevatengi. Makambani anozivikanwa e-cellulose ether munyika dzakabudirira anonyanya kushandisa nzira yekukwikwidzana "yekutarisana nevatengi vakuru vepamusoro-soro + kugadzira mashandisirwo nekushandiswa kwepasi" kugadzira mashandisirwo nemafomura ekushandisa e-cellulose ether, uye kugadzirisa zvigadzirwa zvakasiyana-siyana zvichienderana neminda yakasiyana-siyana yekushandisa kuti zvive nyore kushandisa kwevatengi, uye kukura kudiwa kwemusika wepasi. Makwikwi emabhizinesi e-cellulose ether munyika dzakabudirira abva pakupinda kwechigadzirwa kuenda kumakwikwi mumunda wetekinoroji yekushandisa.
