I-Cellulose isetyenziswa kakhulu kwi-petrochemical, iyeza, i-papermaking, izimonyo, izinto zokwakha, njl njl. Kuyinto yokudibanisa kakhulu, kwaye ukusetyenziswa okuhlukeneyo kuneemfuno zokusebenza ezahlukeneyo kwiimveliso ze-cellulose.
Eli nqaku ikakhulu lizisa ukusetyenziswa kunye nendlela yokuchonga umgangatho we-HPMC (i-hydroxypropyl methylcellulose ether), iindidi ze-cellulose ezisetyenziswa ngokuqhelekileyo kwi-putty powder eqhelekileyo.
I-HPMC isebenzisa umqhaphu osulungekileyo njengeyona nto iphambili ekrwada. Inokusebenza kakuhle, ixabiso eliphezulu kunye nokuchasana okulungileyo kwe-alkali. Ifanelekile iputty enganyangekiyo emanzini kunye nodaka lwepolymer eyenziwe ngesamente, i-lime calcium kunye nezinye izinto ezomeleleyo zealkaline. Uluhlu lwe-viscosity yi-40,000-200000S.
Ezi zilandelayo ziindlela ezininzi zokuvavanya umgangatho we-hydroxypropyl methylcellulose eshwankathelwa nguXiaobian kuwe. Yiza ufunde noXiaobian~
1. Ubumhlophe:
Ewe kunjalo, eyona nto ithatha isigqibo ekumiseleni umgangatho we-hydroxypropyl methylcellulose ayinakuba bubumhlophe nje. Abanye abavelisi baya kongeza ii-agent ezimhlophe kwinkqubo yokuvelisa, kulo mzekelo, umgangatho awukwazi ukugwetywa, kodwa ubumhlophe bekhwalithi ephezulu ye-hydroxypropyl methylcellulose ilungile ngokwenene.
2. Ukulunga:
IHydroxypropyl methylcellulose idla ngokuba ne-fineness ye-80 mesh, 100 mesh kunye ne-120 mesh. I-fineness of particles ihle kakhulu, kwaye ukunyibilika kunye nokugcinwa kwamanzi kukwalungile. Le yi-hydroxypropyl methylcellulose ekumgangatho ophezulu.
3. Ukuhanjiswa kokukhanya:
Faka i-hydroxypropyl methylcellulose emanzini kwaye uyinyibilikise emanzini ixesha elithile ukujonga i-viscosity kunye nokungafihli. Emva kokuba i-gel yenziwe, jonga ukukhanya kwayo, ukuhanjiswa kokukhanya bhetele, iphezulu into enganyibilikiyo kunye nococeko.
4. Umxhuzulane okhethekileyo:
Ubukhulu bobunzima obuthile, bungcono, kuba ubunzima bobunzima obuthile, buphezulu umxholo we-hydroxypropyl methyl kuwo, ngcono ukugcinwa kwamanzi.
