Iimveliso zeGypsum: ziphucula ukusebenza kokucubungula, ziphucula ukunamathela kunye namandla.
Ishishini lamayeza
Njengesixhobo sokongeza amayeza, ingasetyenziswa njengesithambisi, isiqinisi, i-emulsifier, i-film former kunye ne-ejenti yokukhulula ixesha elide.
Isetyenziswa njengesixhobo sokuqhawula, sokuncamathelisa kunye nesokugquma xa kusenziwa iipilisi.
Ihambelana kakuhle ne-biochemical kwaye isetyenziswa kakhulu kumalungiselelo amehlo, ii-capsules kunye namalungiselelo okukhululwa rhoqo.
Ishishini lokutya
Njengesongezelelo sokutya, isetyenziswa kakhulu njenge-thickener, i-emulsifier, i-stabilizer kunye ne-arhente yokwenza ifilimu.
Ifanelekile kwiijam, iziselo, i-ayisikhrim, izinto ezibhakiweyo, njl.njl., ukuze ityebe kwaye iphucule incasa.
Izinto zokuthambisa kunye neemveliso zokhathalelo lomntu
Isetyenziswa njengesithambisi-mafutha kunye ne-emulsifier, esetyenziswa kakhulu kwiimveliso zokhathalelo lolusu, ishampu, i-toothpaste, njl.
Ineempawu ezilungileyo zokufumisa nokuzinzisa, nto leyo ephucula amava okusetyenziswa kwemveliso.
Ezinye iindlela zokusetyenziswa kwemizi-mveliso
Isetyenziswa njengesithambisi, isincamathelisi okanye isixubisisi kwiiseramikhi, amalaphu, ukwenza iphepha, ii-inki, izibulali-zinambuzane kunye neminye imizi-mveliso.
3. Indlela yokusebenzisa
Indlela yokunyibilikisa
Indlela yokusasazwa kwamanzi abandayo: Fafaza i-HPMC kancinci emanzini abandayo, uvuselele rhoqo ide isasazeke ngokulinganayo, uze uyifudumeze iye kuma-30-60℃ uze uyinyibilikise ngokupheleleyo.
Indlela yokunyibilikisa amanzi ashushu: qala ngokufumisa i-HPMC ngamanzi ashushu (angaphezulu kwama-60°C) ukuze idumbe, uze wongeze amanzi abandayo uze uvuselele ukuze inyibilike.
Indlela yokuxuba eyomileyo: xuba i-HPMC nezinye iipowder ezomileyo kuqala, uze wongeze amanzi uze uxube ukuze inyibilike.
Isixa esongeziweyo
Kwishishini lokwakha, isixa esongeziweyo se-HPMC ngokubanzi siphakathi kwe-0.1% ne-0.5%.
Kwimizi-mveliso yokutya kunye namayeza, isixa esongeziweyo silungiswa ngokwenjongo ethile.
4. Amanyathelo okusebenzisa
Iimeko zokugcina
Gcina kwindawo epholileyo, eyomileyo, nengena umoya kakuhle, kuphephe ukufuma kunye nokukhanya kwelanga ngqo.
Gcina kude nemithombo yobushushu, imithombo yomlilo kunye nee-oxidants ezinamandla ukuthintela ukubola nokutsha.
Amanyathelo okuthintela ukuchithwa kwendlu
Kuphephe ukongeza inani elikhulu le-HPMC ngexesha elinye ukuthintela ukwakheka kwamaqhuma kunye nokuchaphazela isiphumo sokunyibilika.
Isantya sokunyibilika sicotha kwindawo enobushushu obuphantsi, kwaye ubushushu bunokwandiswa ngokufanelekileyo okanye ixesha lokuxukuxa linokwandiswa.
Ukhuseleko lokusetyenziswa
I-HPMC yinto engenabungozi kwaye ayinabungozi, kodwa inokubangela ukurhawuzelelwa kokuphefumla kwimeko yomgubo, kwaye kufuneka kuphetshwe uthuli oluninzi.
Kucetyiswa ukuba unxibe imaski kunye neeglasi zeglasi xa usakha ukuze uphephe ukurhawuzelelwa luthuli kwindlela yokuphefumla kunye namehlo.
Ukuhambelana
Xa usebenzisa, qaphela ukuba ukuhambelana nezinye iikhemikhali kuyafuneka, ingakumbi xa ulungiselela izinto zokwakha okanye amayeza.
Kwicandelo lokutya namayeza, kufuneka kuhlangatyezwane nemigaqo nemigangatho efanelekileyo ukuqinisekisa ukhuseleko.
I-hydroxypropyl methylcelluloseisetyenziswa kakhulu kumashishini amaninzi ngenxa yokusebenza kwayo okugqwesileyo. Ngexesha lokusetyenziswa, kuyimfuneko ukuba ube nobuchule bokunyibilikisa kunye nezakhono zokusebenzisa, kwaye unikele ingqalelo kwimicimbi yokugcina kunye nokhuseleko ukuqinisekisa uzinzo kunye nokusebenza kwemveliso. Ukusetyenziswa ngokuchanekileyo kwe-HPMC akunakuphucula kuphela umgangatho wemveliso, kodwa kukwaphucula nokusebenza kakuhle kokwakhiwa kunye nemveliso.
