I-Hydroxypropyl methyl cellulose HPMC ikakhulukazi inamaviscosity amathathu, i-HPMC-100000, HPMC-150000, kanye ne-HPMC-200000 viscosity.Ngokuvamile, i-hydroxypropyl methyl cellulose ene-viscosity ye-100,000 ivame ukusetshenziswa ekukhiqizeni i-putty powder yangaphakathi nangaphandle.I-Cellulose ine-viscosity engu-200,000 futhi isetshenziswa ezintweni zokwakha ezifana nodaka olomile, udaka lwamatshe olulula, udaka lwe-diatom, nokumbozwa kodonga.Umkhiqizo unomphumela omuhle wokugcina amanzi, umphumela omuhle wokujiya, ikhwalithi ezinzile kanye nentengo efanelekile.
IHydroxypropyl methylcellulose HPMC isetshenziswa kabanzi embonini yezinto zokwakha.Inani elikhulu le-cellulose lingasetshenziswa njenge-retarder, i-ejenti yokugcina amanzi, i-thickener kanye ne-binder.I-Cellulose ether idlala indima ebalulekile odakeni olujwayelekile lwengxube eyomile, udaka olusebenza kahle lwangaphandle olufakwa odongeni, udaka oluzilinganisa ngokwalo, ingcina yempushana eyomile, i-ceramic ebopha udaka oluyimpushana eyomile, i-putty yebhilidi esebenza kahle kakhulu, ingaphakathi elikwazi ukumelana nokuqhekeka nangaphandle. i-wall putty, njll. , udaka lwengxube eyomile olungangeni manzi, ukhonkolo lwegypsum, i-ejenti ekhuhlayo emhlophe, amalunga ongqimba oluncane nezinye izinto.Zinomthelela omkhulu ekugcineni amanzi, izidingo zamanzi, ukuzwakala, ukuhlehla kanye nokusebenza kwezinhlelo ze-stucco.Ama-cellulose ether asetshenziswa kakhulu emkhakheni wokwakha afaka i-HEC, i-HPMC, i-CMC, i-PAC, i-MHEC, njll.
I-Nonionic water-soluble cellulose ethers ayizithasiselo zezinto zokwakha eziwusizo ngenxa yezakhiwo zazo ezibophayo, ukuzinza kokuhlakazeka, namandla okugcina amanzi.I-HPMC, i-MC noma i-EHEC isetshenziswa ekwakhiweni okuningi okusekelwe kusimende noma kwe-gypsum, njengodaka lwamatshe, udaka lukasimende, ukunamathela kukasimende, i-gypsum, ingxube kasimende ne-emulsion putty, njll., engathuthukisa ukuhlakazwa kukasimende noma isihlabathi futhi kuthuthukise kakhulu. ukunamathela , okubaluleke kakhulu ku-plaster, usimende we-tile kanye ne-putty.Ngosimende, i-HEC ayigcini nje ngokubuyisela emuva, kodwa futhi i-ejenti yokugcina amanzi.I-HEHPC nayo inale njongo.Ama-cellulose ethers avame ukusetshenziswa ehlanganiswe nama-gluconate osimende njengezithasiselo ezibalulekile zokubuyisela emuva.I-MC noma i-HEC ne-CMC zivame ukusetshenziswa njengengxenye eqinile yephepha lodonga.Ama-cellulose ethers e-cellulose e-viscosity aphakathi nendawo noma aphezulu avame ukusetshenziswa kuma-adhesives odonga kanye nezinto zokwakha.
Umkhiqizo we-Hydroxypropyl methylcellulose we-HPMC uhlanganisa izici eziningi ezibonakalayo namakhemikhali ukuze ube umkhiqizo oyingqayizivele onokusetshenziswa okuningi.Izakhiwo ezihlukahlukene zimi kanje:
(1) Ukugcinwa kwamanzi: Kungagcina umswakama ezindaweni ezinezimbotshana ezifana namabhodi usimende odongeni nezitini.
(2) Izinto zokwenza ifilimu: Ingenza ifilimu esobala, eqinile, ethambile enokumelana nowoyela okuhle kakhulu.
(3) Ukunyibilika kwe-Organic: Lo mkhiqizo uncibilika kwezinye izinyibilikisi zemvelo, njenge-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane kanye nesistimu yezincibilikisi ezakhiwe ngezincibilikizi ezimbili eziphilayo ngezilinganiso ezifanele.
(4) I-Thermal Gelation: Lapho isixazululo esinamanzi salo mkhiqizo sishiswa, sakha ijeli futhi siphenduka isixazululo ngemva kokupholisa.
(5) Umsebenzi ongaphezulu: Nikeza umsebenzi ongaphezulu kusixazululo sokufeza i-emulsification efanelekile ye-colloidal nokuvikelwa, kanye nokuqiniswa kwesigaba.
(6) I-ejenti yokumiswa: I-Hydroxypropyl methylcellulose ingavimbela izinhlayiya eziqinile ukuthi zingahlali, ngaleyo ndlela ivimbele ukwakheka kwemvula.
(7) I-colloid evikelayo: Ingavimbela amaconsi nezinhlayiya ukuthi zihlangane noma zijiye.
(8) Ukunamathela: Kusetshenziswa njengesihlanganisi semibala, imikhiqizo kagwayi, nemikhiqizo yephepha, kunemisebenzi emihle kakhulu.
(9) Ukuncibilika kwamanzi: Lo mkhiqizo ungancibilika emanzini ngezilinganiso ezihlukene, futhi ukugxila kwawo okuphezulu kukhawulelwe kuphela yi-viscosity.
(10) I-Nonionic inertness: Lo mkhiqizo uyi-nonionic cellulose ether futhi awuhlanganisi nosawoti wensimbi noma amanye ama-ion ukuze kwakhe ukuvuza okungancibiliki.
(11) Ukuzinza kwesisekelo se-Acid: kulungele ukusetshenziswa ngaphakathi kwebanga le-pH lika-3.0-11.0.
(12) Ayinambitheki futhi ayinaphunga, ayithinteki ekusetshenzisweni kwe-metabolism;esetshenziswa njengezithasiselo ekudleni nasemthini, awagaywa i-metabolized ekudleni futhi awanikezi ama-calories.
Ngakho-ke, i-hydroxypropyl methylcellulose HPMC ithatha isikhundla esibalulekile embonini yezokwakha, futhi i-cellulose eluhlaza izosetshenziswa kabanzi embonini yezokwakha.Izinga eliphezulu, amanani akhethekile kanye nezinsizakalo ezingcono yilokho abakhiqizi bethu be-cellulose kanye ne-latex powder abahlale bekuphishekela.Ifuture Day ihambisana nefilosofi yebhizinisi "yokusinda ngekhwalithi, ukuthuthukiswa kwesayensi nobuchwepheshe, imakethe ngesithunzi, nokusebenza kahle ngabaphathi".I-hydroxypropyl methylcellulose yethu, impushana ye-latex ehlakazeka kabusha, kanye ne-hydroxyethyl cellulose inikeza imikhiqizo yekhwalithi ephezulu kumakhasimende amaningi.
