Kunyanya kushandiswa kwehydroxypropyl methylcellulose
1. Indasitiri yekuvaka: inoshandiswa sechinhu chinochengetedza mvura uye chinodzoreredza chesamende dhaka kuita kuti dhaka ripombike. Shandisa dhaka, plaster, putty kana zvimwe zvinhu zvekuvaka sechisungirirwa kuti uvandudze kupararira uye kuwedzera nguva yekushandisa. Inoshandiswa senge yekunamira mataira, marble, kushongedza kwepurasitiki, yekunamira inosimudzira, uye inogona zvakare kuderedza huwandu hwesimende. Iyo inochengetedza mvura pfuma yehydroxypropyl methylcellulose HPMC inodzivirira paste kuti isaoma nekukasira nekutsemuka kana yaiswa, uye inowedzera simba mushure mekuoma.
2. Ceramic kugadzira indasitiri: yakashandiswa zvakanyanya seyakanamatira mukugadzira zvigadzirwa zveceramic.
3. Indasitiri yekuputira: inoshandiswa seyakakura, inoparadzanisa uye yakagadzikana mumhizha yekuputira, uye ine kuwirirana kwakanaka mumvura kana organic solvents. Semupendero wepende.
4. Ink kudhinda: inoshandiswa se thickener, dispersant uye stabilizer mumhizha yeinki, uye ine kuwirirana kwakanaka mumvura kana organic solvents.
5. Plastiki: molding release agent, softener, lubricant, nezvimwewo.
6. PVC: Sokuparadzira kwePVC kugadzirwa uye chikuru chekuwedzera chekugadzirira kwePVC nekumisa polymerization.
7. Vamwe: Ichi chigadzirwa chinoshandiswa zvakanyanya muindasitiri yematehwe, mapepa ezvigadzirwa, kuchengetedza michero nemiriwo uye indasitiri yemachira, nezvimwe.
8. Indasitiri yemishonga: kuvhara zvinhu; zvinhu zvemufirimu; chiyero-chinodzora polymer zvinhu zvekugadzirira-kuburitswa gadziriro; stabilizers; kumiswa rubatsiro; mapiritsi ekunamira; kuwedzera viscosity
njodzi dzehutano
Hydroxypropyl methylcellulose yakachengeteka uye haina chepfu uye inogona kushandiswa sechikafu chekuwedzera. Iyo haigadziri kupisa uye haina-kutsamwisa kune ganda uye mucous membranes. Kudya kwezuva nezuva kwe25 mg/kg (FAO/WHO 1985) kunowanzoonekwa kwakachengeteka (FDA1985). Midziyo yekudzivirira inofanira kupfekwa panguva yekushanda.
Environmental Impact yeHydroxypropyl Methylcellulose
Dzivisa kupararira kweguruva kunokonzera kusvibiswa kwemhepo.
Njodzi dzeMuviri uye Kemikari: Dzivisa kusangana nezvinopisa moto, dzivirira kuumbwa kwehuruva yakawanda munzvimbo yakavharwa, uye kudzivirira njodzi dzinoputika.
