Serosindiyo chinhu chikuru chemadziro emasero emiti, uye ndiyo polysaccharide yakapararira zvakanyanya uye yakawanda kwazvo, ichitora anopfuura 50% yehuwandu hwekabhoni muumambo hwemiti. Pakati padzo, huwandu hwe cellulose mudonje huri pedyo ne100%, inova ndiyo sosi chaiyo ye cellulose. Kazhinji huni, cellulose inokwana 40-50%, uye kune 10-30% hemicellulose uye 20-30% lignin. Cellulose ether izwi rekushandisa zvakasiyana-siyana zvinobva mu cellulose yechisikigo sezvinhu zvakabikwa kuburikidza ne etherification. Ichi chigadzirwa chinoumbwa mushure mekunge mapoka e hydroxyl ari pama macromolecule e cellulose atsiviwa zvishoma kana zvachose nemapoka e ether. Kune intra-chain uye inter-chain hydrogen bonds mu macromolecule e cellulose, ayo akaoma kunyungudika mumvura uye anenge ese organic solvents, asi mushure me etherification, kuunzwa kwemapoka e ether kunogona kuvandudza hydrophilicity uye kuwedzera zvakanyanya kunyungudika mumvura uye organic solvents. Hunhu hwekunyungudika.
Cellulose ether ine mukurumbira we "industrial monosodium glutamate". Ine hunhu hwakanaka hwakadai sekusimba kwemvura, kunyungudika kwemvura zvakanaka, kugadzikana kwemushonga kana latex, kugadzira firimu, kuchengetedza mvura, uye kunamira. Haina chepfu uye haina kunaka, uye inoshandiswa zvakanyanya muzvinhu zvekuvaka, mishonga, chikafu, machira, makemikari ezuva nezuva, kutsvaga peturu, migodhi, kugadzira mapepa, polymerization, aerospace nedzimwe nzvimbo dzakawanda. Cellulose ether ine zvakanakira zvekushandiswa kwakakura, kushandiswa kwemayuniti madiki, mhedzisiro yakanaka yekugadzirisa, uye hushamwari hwezvakatipoteredza. Inogona kuvandudza zvakanyanya uye kugadzirisa mashandiro echigadzirwa mumunda wekuwedzera kwayo, izvo zvinobatsira mukuvandudza kushanda zvakanaka kwezviwanikwa uye kukosha kwezvigadzirwa. Zvimwe zvinosimudzira zvakatipoteredza zvakakosha muminda yakasiyana-siyana.
Zvichienderana neionization ye cellulose ether, mhando dzezvinotsiva uye musiyano wekunyungudika, cellulose ether inogona kuiswa muzvikamu zvakasiyana. Zvichienderana nemhando dzakasiyana dzezvinotsiva, cellulose ethers dzinogona kukamurwa kuita single ethers uye mixed ethers. Zvichienderana nekunyungudika, cellulose ether inogona kukamurwa kuita zvigadzirwa zvinonyungudika mumvura uye zvisinganyungudike mumvura. Zvichienderana neionization, inogona kukamurwa kuita ionic, non-ionic uye mixed products. Pakati pe water-soluble cellulose ethers, non-ionic cellulose ethers dzakadai seHPMC dzine resistance iri nani yekupisa uye salt resistance kupfuura ionic cellulose ethers (CMC).
Cellulose ether inovandudza sei muindasitiri?
Cellulose ether inogadzirwa nedonje rakanatswa kuburikidza ne alkaliization, etherification nedzimwe nhanho. Maitiro ekugadzira HPMC yemhando yemishonga uye HPMC yemhando yekudya akafanana. Kana tichienzanisa ne cellulose ether yemhando yekuvaka, maitiro ekugadzira HPMC yemhando yemishonga uye HPMC yemhando yekudya anoda etherification yakarongwa, iyo yakaoma, yakaoma kudzora maitiro ekugadzira, uye inoda kuchena kwakanyanya kwemidziyo nenzvimbo yekugadzira.
Zvichienderana nedata rakapihwa neChina Cellulose Industry Association, kugona kwese kwekugadzira kwevagadziri ve non-ionic cellulose ether vane kugona kukuru kwekugadzira mudzimba, vakaita seHercules Temple, Shandong Heda, nezvimwewo, kunodarika 50% yehuwandu hwese hwekugadzira munyika. Kune vamwe vagadziri ve non-ionic cellulose ether vane kugona kwekugadzira kusingasviki matani 4,000. Kunze kwemabhizinesi mashoma, mazhinji acho anogadzira cellulose ethers dzekuvaka dzakajairwa, dzine kugona kwekugadzira kunosvika matani 100,000 pagore. Nekuda kwekushaya simba remari, mabhizinesi madiki mazhinji anokundikana kuzadzisa zvinodiwa mukuchengetedza nharaunda mukurapa mvura nekurapa gasi reutsi kuitira kuderedza mari yekugadzira. Sezvo nyika neruzhinji rwese zvichinyanya kutarisisa kuchengetedzwa kwenharaunda, mabhizinesi ari muindasitiri asingakwanise kuzadzisa zvinodiwa zvekuchengetedzwa kwenharaunda achavhara zvishoma nezvishoma kana kuderedza kugadzirwa. Panguva iyoyo, huwandu hweindasitiri yekugadzira cellulose ether yenyika yangu huchawedzera zvakanyanya.
Mitemo yekuchengetedza nharaunda yemumba iri kuramba ichioma, uye zvinodiwa zvakasimba zviri kupihwa tekinoroji yekuchengetedza nharaunda uye mari mukugadzirwa kwayo.ether ye cellulose. Matanho epamusoro ekuchengetedza nharaunda anowedzera mutengo wekugadzira mabhizinesi uye anoumbawo muganho wakakwirira wekuchengetedza nharaunda. Makambani asingakwanise kuzadzisa zvinodiwa zvekuchengetedza nharaunda angangovharwa zvishoma nezvishoma kana kuderedza kugadzirwa nekuda kwekutadza kuzadzisa zvinodiwa zvekuchengetedza nharaunda. Zvichienderana neprospectus yekambani, mabhizinesi anoderedza kugadzirwa zvishoma nezvishoma uye anomisa kugadzirwa nekuda kwezvinhu zvekuchengetedza nharaunda anogona kusanganisira huwandu hwese hwematani angangoita 30,000 pagore emhando yesimbi yekuvaka cellulose ether, iyo inobatsira pakuwedzera mabhizinesi anobatsira.
Zvichibva pa cellulose ether, inoramba ichienderera mberi kusvika kune zvigadzirwa zvepamusoro-soro uye zvine kukosha kwakanyanya
