Ukuhlelwa kweeMveliso zeMethyl Cellulose

Iimveliso zeMethyl cellulose (MC) zinokuhlelwa ngokusekelwe kwizinto ezahlukeneyo ezifana nebakala le-viscosity, i-degree of substitution (DS), ubunzima be-molecular, kunye nokusetyenziswa.Nalu uluhlu oluqhelekileyo lweemveliso ze-methyl cellulose:

1. IBanga leViscosity:
   • Iimveliso ze-Methyl cellulose zihlala zihlelwa ngokusekelwe kumabakala abo e-viscosity, ahambelana ne-viscosity yabo kwizisombululo zamanzi.I-viscosity yezisombululo ze-methyl cellulose ngokuqhelekileyo ilinganiswa kwi-centipoise (cP) kwindawo ethile kunye nobushushu.Amanqaku e-viscosity aqhelekileyo aquka i-viscosity ephantsi (LV), i-viscosity ephakathi (MV), i-viscosity ephezulu (HV), kunye ne-ultra-high viscosity (UHV).
2. Isidanga soTshintsho (DS):
   • Iimveliso ze-Methyl cellulose nazo zinokuhlelwa ngokusekelwe kwiqondo labo lokutshintshwa, elibhekiselele kumyinge wenani lamaqela e-hydroxyl ngeyunithi yeglucose ethe yatshintshwa ngamaqela e-methyl.Amaxabiso aphezulu e-DS abonisa iqondo elikhulu lokutshintsha kwaye ngokuqhelekileyo kubangela ukunyibilika okuphezulu kunye namaqondo obushushu asezantsi.
3. Ubunzima beMolekyuli:
   • Iimveliso ze-Methyl cellulose zinokuhluka kubunzima bemolekyuli, ezinokuchaphazela iipropathi zazo ezinje nge-solubility, viscosity, kunye nokuziphatha kwe-gelation.Iimveliso eziphezulu ze-molecular weight methyl cellulose zikholisa ukuba ne-viscosity ephezulu kunye neempawu ezinamandla ze-gelling xa kuthelekiswa neemveliso ezinobunzima be-molecular.
4. Isicelo-AmaBanga athile:
   • Iimveliso ze-Methyl cellulose zinokuhlelwa ngokusekelwe kwizicelo ezijoliswe kuzo.Umzekelo, kukho amabanga athile e-methyl cellulose elungiselelwe ukwenziwa kwamayeza, iimveliso zokutya, izinto zokwakha, izinto zokhathalelo lomntu, kunye nezinye izicelo zemizi-mveliso.La mabanga anokuba neepropathi ezilungiselelwe ukuhlangabezana neemfuno zezicelo zazo.
5. AmaBanga awodwa:
   • Ezinye iimveliso ze-methyl cellulose ziyilelwe usetyenziso olukhethekileyo okanye zineempawu ezizodwa ezilungiselelwe ukusetyenziswa okuthile.Imizekelo ibandakanya i-methyl cellulose derivatives kunye nokuzinza okuphuculweyo kwe-thermal, ukuphuculwa kweempawu zokugcina amanzi, iimpawu zokukhululwa ezilawulwayo, okanye ukuhambelana nezinye izongezo okanye izinyibilikisi.
6. Amagama oRhwebo kunye neempawu:
   • Iimveliso zeMethyl cellulose zinokuthengiswa phantsi kwamagama ahlukeneyo orhwebo okanye iibrendi ngabavelisi abohlukeneyo.Ezi mveliso zinokuba neempawu ezifanayo kodwa zinokwahluka ngokwemigaqo, umgangatho, kunye nokusebenza.Amagama orhwebo aqhelekileyo e-methyl cellulose aquka i-Methocel®, i-Cellulose Methyl, kunye ne-Walocel®.

Iimveliso ze-methyl cellulose zinokuhlelwa ngokusekelwe kwizinto ezifana nebakala le-viscosity, i-degree of substitution, ubunzima be-molecular, amabakala athile okusebenza, amabakala akhethekileyo, kunye namagama orhwebo.Ukuqonda olu lwahlulo lunokunceda abasebenzisi bakhethe imveliso ye-methyl cellulose efanelekileyo kwiimfuno zabo ezithile kunye nokusetyenziswa.
