Hydroxypropyl Methyl Cellulose Yakaviriswa

Hydroxypropyl methylcellulose inoshandiswa seyakabikwa kugadzira mafuta, anogona kupedzisa kushandiswa kweshuga, kuvandudza mwero wekushandiswa kwezvinhu zvakabikwa, kuderedza huwandu hwasara hwe substrate mumuto wekuvirisa, kuderedza mutengo wekuchenesa mvura yetsvina, uye kugadzira chimiro chechimiro. ye hydroxypropyl methylcellulose inobatsira Inobatsira pakugadzirisa batch, batch uye inoenderera mberi yekuvirisa maitiro, kudzivirira kushandiswa kwematishu uye dilution tsika zvine chekuita nezvinetso;zvakare inobatsira pakugadzirisa kwekuvirisa maitiro.

Hydroxypropyl methylcellulose, mbishi cellulose, inogona kunatswa donje, kana inogona kuva huni pulp.Inoda kupatsanurwa pamberi kana panguva ye alkalization.Izvo zvinodikanwa kupuruzira iyo cellulose mbishi zvinhu nesimba remagetsi kuti uderedze crystallinity uye polymerization degree, kuwedzera nzvimbo yayo, uyezve kuvandudza iyo trihydroxyl degree uye kemikari kuita kugona kweiyo reactant pane glucose mhete ye cellulose polymer.

Kunyangwe iyo synthesis yehydroxypropyl methylcellulose haina kuomesesa, iyo alkali, mbishi zvinhu zvinoputswa uye alkaliized.Etherification, solvent recovery, centrifugal kupatsanura, kugeza nekuomesa munzvimbo dzakasiyana siyana, asi inosanganisira akawanda akakosha matekinoroji uye ruzivo rwakapfuma rwemukati.Kune akasiyana marudzi ezvigadzirwa, nharaunda yega yega ine ichangoburwa kudzora mamiriro, senge tembiricha, nguva, kudzvanywa uye kuyerera kwekudzora kudzora zvivakwa zvekubatsira uye midziyo yekudzora ndiyo vimbiso yekugadzikana kwemhando yechigadzirwa, yakavimbika dhizaini system, uye yakanaka.

Sezvo kuita kwehydroxypropyl methylcellulose kwakafanana nekwemamwe ether-soluble ethers, inogona kushandiswa semugadziri wemufirimu, thickener, emulsifier uye stabilizer mulatex pendi uye mvura-soluble resin coating zvinyorwa, abrasion resistance, Uniform coating uye. adhesion, uye yakagadziridzwa tension, kugadzikana kune acids uye zvigadziko, uye kuenderana nesimbi pigment.Hydroxypropyl methylcellulose ine mhedzisiro yakanaka seyakakora yemvura yakachena-yakavakirwa polyvinyl acetate pendi.Dhigirii yekutsiviwa kwe cellulose ether inovandudzwa, uye kushorwa kwebhakitiriya kunovandudzwa zvakare.
