1. Kushandiswa kukuru kwehydroxypropyl methylcellulose
1. Indasitiri yekuvaka: Semugadziri wekuchengetedza mvura uye retarder yesamende dhaka, inogona kuita kuti dhaka ripombike.Mupurasita, gypsum, putty poda kana zvimwe zvekuvaka sechibatiso chekuvandudza kupararira uye kurebesa nguva yebasa.Inogona kushandiswa sekuisa mataira, marble, kushongedzwa kwepurasitiki, paste yekusimbisa, uye inogona zvakare kuderedza huwandu hwesimende.Iko kuchengetedza kwemvura kuita kwehydroxypropyl methylcellulose HPMC inodzivirira slurry kubva pakutsemuka nekuda kwekuoma nekukurumidza mushure mekushandisa, uye inowedzera simba mushure mekuoma.
2. Ceramic kugadzira indasitiri: Inoshandiswa zvakanyanya sebhainda mukugadzira zvigadzirwa zveceramic.
3. Indasitiri yekuputira: Inoshandiswa seyakakura, inoparadzanisa uye yakagadzikana mumhizha yekuputira, uye ine kuwirirana kwakanaka mumvura kana organic solvents.Sekubvisa pendi.
4. Ink kudhindwa: Inoshandiswa seyakakora, dispersant uye stabilizer muindasitiri yeinki, uye ine kuenderana kwakanaka mumvura kana organic solvents.
5. Plastiki: inoshandiswa sekugadzira kuburitsa agent, softener, lubricant, nezvimwe.
6. Polyvinyl chloride: Inoshandiswa seanoparadzira mukugadzirwa kwepolyvinyl chloride, uye ndiyo inonyanya kubatsira mumiririri wekugadzira PVC nekumisa polymerization.
7. Vamwe: Ichi chigadzirwa chinoshandiswawo zvakanyanya mumatehwe, zvigadzirwa zvemapepa, kuchengetedza michero nemiriwo uye maindasitiri emachira.
8. Indasitiri yemishonga: kuvhara zvinhu;membrane zvinhu;chiyero-chinodzora polymer zvinhu zvekugadzirira-kuburitswa gadziriro;stabilizers;suspending agents;mapiritsi ekunamira;viscosity-inowedzera vamiririri
njodzi yehutano
Hydroxypropyl methylcellulose yakachengeteka uye isina chepfu, inogona kushandiswa sechikafu chekuwedzera, haina kupisa, uye haina kutsamwa kune ganda uye mucous membranes.Inowanzoonekwa seyakachengeteka (FDA1985), ine zuva nezuva inobvumidzwa ye25mg/kg (FAO/WHO 1985), uye zvekudzivirira zvinofanirwa kupfekwa panguva yekushanda.
Kukanganisa kwezvakatipoteredza kwehydroxypropyl methylcellulose
Dzivisa kukanda huruva zvisina tsarukano kukonzeresa kusvibiswa kwemhepo.
Njodzi dzemuviri nemakemikari: dzivisa kusangana nezvinopisa moto, uye dzivirira kuumba guruva rakakura munzvimbo yakavharwa kudzivirira njodzi dzinoputika.
