I-cellulose ethers esetyenziswa ngokuqhelekileyo ibandakanya i-HEC, i-HPMC, i-CMC, i-PAC, i-MHEC, njl. njl. I-ether ye-cellulose e-soluble yamanzi e-nonionic inokubambisana, ukuzinza kwe-dispersion kunye nokugcinwa kwamanzi, kwaye iyongezwa luncedo kwizinto zokwakha.I-HPMC, i-MC okanye i-EHEC isetyenziswa kwizakhiwo ezininzi ezisekwe kwisamente okanye kwigypsum, njengodaka lwesamente, udaka lwesamente, udaka lwesamente, igypsum, umxube wesamente kunye ne-milky putty, njl. njl., enokuphucula ukusasazwa kwesamente okanye isanti kunye phucula kakhulu i-Adhesion, ebaluleke kakhulu kwi-plaster, i-tile samente kunye ne-putty.I-HEC isetyenziswe kwi-samente, kungekhona nje njenge-retarder, kodwa kunye ne-agent yokugcinwa kwamanzi, kwaye i-HEHPC nayo isetyenziswe kule nkalo.I-MC okanye i-HEC zihlala zisetyenziswa kunye ne-CMC njengenxalenye eqinileyo yephepha lodonga.I-Medium-viscosity okanye i-high-viscosity cellulose ethers idla ngokusetyenziswa kwi-wallpaper encamathiselwe izinto zokwakha.
IHydroxypropyl methylcelluloseHPMCisetyenziswa ngokubanzi kwimveliso yangaphakathi kunye nodonga lwangaphandle lwe-putty powder kunye ne-viscosity ye-cellulose ye-100,000, kudaka olomileyo lwe-powder, udaka lwe-diatom kunye nezinye izinto zokwakha, i-cellulose ene-viscosity ye-200,000 isetyenziswa ngokuqhelekileyo, kunye nokuzilinganisa kunye nokunye. iimbumba ezikhethekileyo, i-cellulose ene-viscosity ye-400 isetyenziswa ngokuqhelekileyo.I-Viscosity cellulose, le mveliso inesiphumo esihle sokugcina amanzi, isiphumo esihle sokuqina kunye nomgangatho ozinzile.I-HPMC isetyenziswa ngokubanzi kushishino lwezixhobo zokwakha kwaye isetyenziswa kwisixa esikhulu.I-Cellulose ingasetyenziswa njenge-retarder, i-arhente yokugcina amanzi, i-thickener kunye ne-binder.I-Cellulose ether idlala indima ebalulekileyo kudaka oluqhelekileyo oluxubeneyo, udaka lwangaphandle lokugquma eludongeni, udaka oluzilinganisa, udaka olomileyo olunamathelisa, udaka lwethayile, umgubo weputty, iputty yangaphakathi nangaphandle eludongeni, udaka olungangenwa manzi, amalungu abhityileyo, njl. ., banempembelelo ebalulekileyo kugcino lwamanzi, imfuno yamanzi, ukuqina, ukuncipha kunye nokusebenza kwenkqubo yestucco.
Iimveliso ze-Hydroxypropyl methylcellulose ze-HPMC zidibanisa iipropathi ezininzi zomzimba kunye neekhemikhali ukuze zibe yimveliso ekhethekileyo enokusetyenziswa ngeendlela ezininzi.Iipropati ezahlukeneyo zezi zilandelayo:
◆ Ukugcinwa kwamanzi: Kunokugcina ukufuma kwiindawo ezivulekileyo ezifana neebhodi zesamente kunye nezitena eludongeni.
◆ Ukwenza ifilimu: Inokwenza ifilimu ecacileyo, eyomeleleyo kunye nethambileyo enokumelana neoli.
◆I-Organic Solubility: Imveliso iyanyibilika kwezinye izinyibilikisi ze-organic, ezifana ne-ethanol/amanzi, ipropanol/amanzi, i-dichloroethane kunye nenkqubo yokunyibilikisa eyenziwe zizinyibilikisi ezimbini eziphilayo.
◆ I-Gelation ye-Thermal: Isisombululo samanzi semveliso siya kwenza i-gel xa ishushu, kwaye i-gel eyenziwe iya kuba sisisombululo kwakhona emva kokupholisa.
◆ Umsebenzi ongaphezulu: Ukubonelela ngomsebenzi ongaphezulu kwisisombululo sokufezekisa i-emulsification efunekayo kunye ne-colloid yokukhusela, kunye nokuzinza kwesigaba.
◆ Ukumiswa: I-Hydroxypropyl methylcellulose inokuthintela iinqununu eziqinileyo ekuzinzeni, ngaloo ndlela zivimbela ukubunjwa kwe-precipitates.
◆I-colloid ekhuselayo: Inokuthintela amaconsi kunye namasuntswana ukuba adibanise okanye adibanise.
◆Ukuncamathelisa: Isetyenziswa njengento yokuncamathelisa ibala, iimveliso zecuba nemveliso yephepha, inemisebenzi ebalaseleyo.
◆ Ukunyibilika kwamanzi: Imveliso inokunyibilika emanzini ngamanani ahlukeneyo, kwaye ukuxinwa kwayo okuphezulu kunqunyelwe kuphela yi-viscosity.
◆ I-inertness engekho i-ionic: Imveliso yi-ether ye-cellulose e-non-ionic, engadibanisi neetyuwa zetsimbi okanye ezinye ii-ion ukwenza i-insoluble precipitates.
◆ Ukuzinza kwe-Acid-base: ilungele ukusetyenziswa ngaphakathi koluhlu lwe-PH3.0-11.0.
◆ Ayinancasa kwaye ayinavumba, ayichatshazelwa yimetabolism;zisetyenziswe njengezongezo zokutya kunye neziyobisi, aziyi kuchithwa ekutyeni, kwaye aziyi kunika ubushushu.
