Indima ebalulekileyo yokunyibilika kwamanziihydroxypropyl methyl cellulose HPMCkudaka lubalulekile kwimiba emithathu, enye yeyona igqwesileyo yogcino lwamanzi isakhono sobuchwephesha, ezimbini ngumonakalo kwi-viscosity kunye nokunyanzeliswa kodaka, ezintathu yintsebenziswano nesamente.Ukugcinwa kakubi kwamanzi odaka kuyo yonke inkqubo yothutho kulula ukwahlula ukuphuma kwamanzi, ukusasazeka kumphezulu wezinto ezinobungozi, amanzi amaninzi kulula ukufunxwa ukugaywa, ukuvelisa utshintsho lwempawu zodaka, udaka phantsi umonakalo yonke i-coagulation eqhelekileyo kunye namaqhekeza amancinci ezinto ezikrwada phakathi kwe-bonding kwaye ke ukunciphisa amandla okuxinzelela eludongeni lwe-masonry.Ukugcinwa kwamanzi kodaka kucaciswa ngohlulo.
Inkulu i-viscosity yei-hydroxypropyl methyl celluloseI-HPMC, kokukhona ukugcinwa kwamanzi ngcono, kokukhona i-viscosity yesisombululo se-polymer esimanzi.Ubude kunye nokumila kwetsheyini ye-molecular kuxhomekeke kwi-molecular mass ye-polymer (iqondo lokushisa lokutshintsha kweglasi).Inani lamaqela asebenzayo nalo lichaphazela uluhlu lwe-viscosity.
IHydroxypropyl methyl cellulose HPMC eyakhe ugcino lwamanzi ukusebenza ukusuka kwi-hydroxypropyl methyl cellulose ekunyibilikeni kwayo kunye nosetyenziso lwamanzi.Kuyaziwa ukuba i-cellulose ayinyibiliki emanzini ngenxa yesakhiwo sayo esiphezulu se-crystalline, nangona i-molecular chain ye-fiber inamaqela amaninzi e-OH ane-hydrated kakhulu.
I-superstrong covalent bonds kunye ne-van der Waals imikhosi phakathi kwezakhiwo ze-molecular ayinakuhlawulwa ngenxa yesakhono se-hydration samaqela e-methyl yedwa.Ngoko ke, inokuchithwa kuphela emanzini.Xa iimolekyuli ezithatha indawo zingeniswa, hayi kuphela iimolekyuli ezibambeleyo ezitshabalalisa ikhonkco le-hydrogen, kodwa kunye neebhondi ze-covalent kwikhonkco le-hydrogen zitshatyalaliswa ziimolekyuli ezithatha indawo zeedge kumatyathanga angabamelwane.Okukhona kufakwe endaweni, kokukhona isithuba esikhulu kwimolekyuli.Okukhona kuluncedo olukhulu lokuqhawula iibhondi ze-covalent.Xa i-fiber lattice iqhubeka isanda, isisombululo esinamanzi singena kwaye i-hydroxypropyl methyl cellulose iba yi-soluble yamanzi, ekhokelela kwisisombululo se-viscous esiphezulu.
Njengoko amaqondo obushushu enyuka, i-polymer's hydration iyancipha kwaye amanzi akhutshelwa ngaphandle kumbindi wekhonkco.Xa kususwa amanzi aneleyo, imolekyuli iyaqokelelana ngokuthe ngcembe, ivelisa uthungelwano olunamacala amathathu ezicubu ezinokolulwa.I-viscosity, i-dosage, ubungakanani bamasuntswana kunye nobushushu besicelo se-hydroxypropyl methyl cellulose zizinto ezonakalisa ukusebenza kokugcinwa kwamanzi kwidaka.
I-Hydroxypropyl methyl cellulose viscosity ihlukaniswe ibe: i-viscosity 100,000, i-viscosity 150,000, i-viscosity 200,000.
Ungayikhetha njani i-hydroxypropyl methyl cellulose?
I-100,000 viscosity hydroxypropyl methyl cellulose ingasetyenziswa njenge-putty yodonga lwangaphakathi.Isibophelelo sethayile.I-arhente ye-Caulking.Udaka lwekhonkrithi oludityanisiweyo.Ukuqina okuphezulu okungacukiyo kwisixhobo sokugrumba.
I-inorganic insulation insulation mortar specification iphezulu, i-viscosity ye-150 lamawaka e-hydroxypropyl methyl cellulose okanye i-200 lamawaka e-hydroxypropyl methyl cellulose.Ukuba ukhetha isiqhamo esitsha ukuba i-viscosity yi-100 lamawaka, velisa ukuhamba ukuxhoma into elula kakhulu.
Indima ephambili ye-methyl cellulose kukugcina amanzi, kulandelwa kukuqina.Yiba nesithukuthezi ngomgubo womntwana kwindonga yangaphakathi, ukuba inamanzi angcono ukunyibilika kunye ne-viscosity engaphantsi (70000-80000), isenokusebenza.Xa i-viscosity idlula i-100,000, i-viscosity ayinabungozi ekugcinweni kwamanzi.Kwimveliso kunye nokuveliswa kwe-putty yodonga lwangaphakathi, akukho mfuneko yokukhetha i-viscosity ye-200,000.Ngenxa yokuba i-viscosity inkulu kakhulu, kunzima ukukrwela kunye nokukrazula ngobuninzi.
I-Hydroxypropyl methyl cellulose isebenzisa i-viscosity ye-100,000.
