Ntchito zazikulu za hydroxypropyl methylcellulose
1. Makampani omanga: amagwiritsidwa ntchito ngati chosungira madzi komanso chotsalira pamatope a simenti kuti apangitse matope kuti azipopa.Gwiritsani ntchito matope, pulasitala, putty kapena zinthu zina zomangira ngati chomangira kuti muzitha kufalikira ndikuwonjezera nthawi yogwira ntchito.Amagwiritsidwa ntchito ngati kupaka matailosi, nsangalabwi, zokongoletsera zapulasitiki, zowonjezera zowonjezera, komanso zimatha kuchepetsa kuchuluka kwa simenti.Katundu wosunga madzi wa hydroxypropyl methylcellulose HPMC amalepheretsa phala kuti lisamawume mwachangu komanso kusweka likagwiritsidwa ntchito, ndipo limawonjezera mphamvu pambuyo pouma.
2. Makampani opanga Ceramic: amagwiritsidwa ntchito kwambiri ngati zomatira popanga zinthu za ceramic.
3. Kupaka mafakitale: kumagwiritsidwa ntchito ngati thickener, dispersant ndi stabilizer mu makampani ❖ kuyanika, ndi zogwirizana bwino m'madzi kapena organic solvents.Monga chochotsera utoto.
4. Kusindikiza kwa inki: kumagwiritsidwa ntchito ngati thickener, dispersant ndi stabilizer mu makampani a inki, ndipo zimakhala bwino m'madzi kapena zosungunulira za organic.
5. Pulasitiki: akamaumba kumasulidwa wothandizira, softener, lubricant, etc.
6. PVC: Monga dispersant kwa PVC kupanga ndi chowonjezera chachikulu pokonzekera PVC ndi kuyimitsidwa polymerization.
7. Zina: Izi zimagwiritsidwanso ntchito kwambiri pazikopa, makampani opanga mapepala, kusunga zipatso ndi masamba ndi mafakitale a nsalu, etc.
8. Makampani opanga mankhwala: zida zokutira;filimu zipangizo;kuwongolera-kuwongolera zida za polima pokonzekera kumasulidwa kosalekeza;stabilizers;chithandizo chamankhwala;zomatira piritsi;kuwonjezeka mamasukidwe akayendedwe
zoopsa zaumoyo
Hydroxypropyl methylcellulose ndi yotetezeka komanso yopanda poizoni ndipo ingagwiritsidwe ntchito ngati chowonjezera cha chakudya.Sichimatulutsa kutentha ndipo sichimakwiyitsa khungu ndi mucous nembanemba.Kudya tsiku ndi tsiku kwa 25 mg/kg (FAO/WHO 1985) nthawi zambiri kumawonedwa ngati kotetezeka (FDA1985).Zida zodzitetezera ziyenera kuvala panthawi yogwira ntchito.
Environmental Impact ya Hydroxypropyl Methylcellulose
Pewani fumbi kumwazikana mwachisawawa kumayambitsa kuipitsa mpweya.
Zowopsa Zakuthupi ndi Zamankhwala: Pewani kukhudzana ndi magwero amoto, pewani kupanga fumbi lambiri pamalo otsekedwa, ndipo pewani zoopsa zomwe zingaphulike.
