Impembelelo ye-cellulose ether kwi-adhesion of mortar

Intshayelelo

Ukusetyenziswa kwe-cellulose ether kumdaka kuye kwanda kakhulu kwishishini lokwakha. I-cellulose ether i-polymer ephuma kwi-cellulose, efumaneka kwiindonga zeeseli zezityalo. Isetyenziswe njengesongezo sokuphucula ukusebenza kwezinto zokwakha. Enye yeenzuzo eziphambili zokusebenzisa i-cellulose ether kumdaka kukukwazi ukuphucula iimpawu zokubambelela kwizinto eziphathekayo.

Injongo yeli phepha kukuxoxa ngempembelelo ye-cellulose ether kwi-adhesion of mortar. Iphepha liya kuqala ngokuxoxa ngeempawu ze-cellulose ether kunye nendlela echaphazela ngayo ukunamathela komdaka. Emva koko iya kuxoxa ngeentlobo ezahlukeneyo ze-cellulose ether kunye neempawu zazo. Ekugqibeleni, iphepha liya kuqukumbela ngokuxoxa ngeenzuzo zokusebenzisa i-cellulose ether kudaka.

Iipropati zeEtere zeSelulosi

I-Cellulose ether yipolymer enyibilikayo emanzini ephuma kwi-cellulose. Ngokuqhelekileyo isetyenziswe njengesongezo kwizinto zokwakha njengoko iphucula iipropati zezinto eziphathekayo. Ipolymer yenziwe ngamamolekyuli eglucose adityaniswe yi-β-1,4-glycosidic bond. Iimolekyuli ze-ether cellulose ziyaguqulwa ke ukuze zihambelane nezicelo ezithile.

I-ether ye-cellulose iphucula ukunamathela kodaka ngokusebenza njenge-binder. Yandisa i-viscosity yodaka, ivumela ukuba ibambelele kwiindawo ezingcono. Iimolekyuli ze-cellulose ether nazo zinobudlelwane obuphezulu bamanzi, obuvumela ukuba bathathe kwaye bagcine ukufuma.

Iindidi zeCellulose Ether

Kukho iintlobo ezahlukeneyo ze-cellulose ether ezisetyenziswa kwishishini lokwakha. Ezona ntlobo zintathu ziqhele ukusetyenziswa yi-hydroxyethyl cellulose (HEC), i-methyl cellulose (MC), kunye ne-carboxymethyl cellulose (CMC). Uhlobo ngalunye lwe-cellulose ether luneempawu zalo ezikhethekileyo, ezenza ukuba zilungele izicelo ezahlukeneyo.

I-Methyl Cellulose (MC)

I-Methyl cellulose luhlobo lwe-cellulose ether esetyenziswa ngokuqhelekileyo kushishino lokwakha. Ineempawu ezigqwesileyo zokugcina amanzi, ezenza ukuba zilungele ukusetyenziswa kwimibhobho yomxube owomileyo. I-MC ikwanazo nefuthe lokujiya xa idityaniswe emanzini, iyenza ilungele ukusetyenziswa ekunikezeni nasekutyabekeni iidaka. Enye ipropati ye-MC yikhono layo lokuphucula ukudibanisa komdaka, okwandisa iimpawu zayo zomatshini.

Iselulosi yeHydroxyethyl (HEC)

I-HEC yolunye uhlobo lwe-ether ye-cellulose esetyenziswa ngokuqhelekileyo kushishino lokwakha. Iyaziwa ngeempawu zayo ezigqwesileyo zokugcina amanzi, ezenza ukuba zilungele ukusetyenziswa kwimibhobho yomxube omanzi. I-polymer nayo inomphumo wokuqina xa ifakwe emanzini, okwenza kube yinto efanelekileyo yokusetyenziswa kwi-adhesives tile kunye ne-grouts. I-HEC iphucula ukunamathela komdaka ngokusebenza njenge-binder, eyandisa amandla ayo okunamathela kwiindawo.

I-Carboxymethyl Cellulose (CMC)

I-CMC luhlobo lwe-ether yeselulosi esetyenziswa rhoqo kushishino lokwakha. Iyaziwa ngokugqwesileyo kokugcina amanzi, okwenza ukuba ilungele ukusetyenziswa kuzo zonke iintlobo zodaka. I-CMC ine-viscosity ephezulu, eyenza ilungele ukusetyenziswa kudaka olufuna umgangatho ophezulu wokusebenza. Ipolymer ikwaphucula ukuncamathela kodaka ngokusebenza njengesibophelelo.

Iinzuzo zokusebenzisa i-Cellulose Ether kwi-Mortar

Ukusetyenziswa kwe-cellulose ether kumdaka kuneenzuzo ezininzi. Okokuqala, iphucula ukunamathela kwezinto, ivumela ukuba ibambelele kwiindawo ezingcono. Okwesibini, iphucula ukusebenza kodaka, okwenza kube lula ukuyifaka. Okwesithathu, iphucula iipropati zokugcina amanzi kwizinto eziphathekayo, ezivumela ukuba zigcine iimpawu zayo ngokuhamba kwesikhathi. Ekugqibeleni, iphucula iimpawu zomatshini wodaka, ukwandisa ukuqina kwayo.

Ukuqukumbela

I-Cellulose ether yipolymer enyibilikayo emanzini ephuma kwi-cellulose. Ngokuqhelekileyo isetyenziswe njengesongezo kwizinto zokwakha njengoko iphucula iipropati zezinto eziphathekayo. I-polymer iphucula ukunamathela kodaka ngokusebenza njenge-binder, eyandisa ukukwazi kwayo ukunamathela kwiindawo. Kukho iintlobo ezahlukeneyo ze-cellulose ether ezisetyenziswa kwishishini lokwakha kwaye uhlobo ngalunye luneempawu zalo ezizodwa. Izibonelelo zokusebenzisa i-cellulose ether kwi-mortar ibandakanya ukuphuculwa kokubambelela, ukusebenza, ukugcinwa kwamanzi, kunye neempawu zomatshini.
