Indima ye-cellulose ether ekuqulunqweni kwe-plaster yodonga

Udonga lwe-stucco luyinxalenye ebalulekileyo yoyilo lwangoku, lubonelela ngokugqwesa kunye nokugqitywa okunomtsalane kwiindonga.Esi sixhobo sihlala sineentlobo ezahlukeneyo zezithako ezifana nesamente, isanti kunye namanzi.Nangona kunjalo, ukongezwa kwe-cellulose ether kuzuza ukuthandwa ngenxa yeempawu zayo ezizodwa, eziphucula ukusebenza kweeplaster eludongeni ngeendlela ezininzi.I-cellulose ethers i-hydrocolloids ephuma kwizinto zezityalo ezisetyenziswa ngokubanzi njengezongezo ezisebenzayo kwiinkqubo ezahlukeneyo, kubandakanywa ukwakhiwa kwe-plaster yodonga.Kule nqaku, sixubusha indima ye-cellulose ether kwi-formulation ye-plaster yodonga kunye nendlela enokuphucula ngayo umgangatho wodonga.

Ukuphucula ukuqhubekeka kunye nokunamathela okumanzi

Omnye weyona misebenzi ibalulekileyo ye-cellulose ethers ekuqulunqweni kwe-plaster eludongeni kukuba iphucula ukusebenza komxube we-plaster.I-cellulose ethers inyibilika ngokugqithisileyo emanzini kwaye xa idityaniswe kumxube we-plaster yodonga zenza umxube we-homogeneous kwaye uzinzile.Ukongeza i-cellulose ethers kumxube we-stucco kuphucula ukunamathela okumanzi, okwenza kube lula ukusebenzisa i-stucco eludongeni.

Ekubeni i-cellulose ether iyipolymer enyibilikayo emanzini, ilibazisa ukufunxwa kwamanzi kwi-plaster yodonga kwaye ngaloo ndlela icotha inkqubo yokomisa.Le propati ivumela udaka ukuba luhlale lusebenza ixesha elide, luvumela abakhi ukuba bafezekise iindawo ezigudileyo.Oku kulibaziseka ekufunxeni kwamanzi kukwanceda ekunciphiseni ukuqhekeka kunye nokuphucula umgangatho opheleleyo we-plaster yodonga.

ukunciphisa ukucutheka

Udaka oludongeni luthanda ukuncipha njengoko lusoma, nto leyo enokukhokelela ekuqhekekeni kunye nezinye iziphene.Ukusetyenziswa kwe-cellulose ethers kwi-stucco formulations kunokunciphisa ukucutheka kodaka eludongeni.I-ether ye-cellulose yenza umxube we-homogeneous kunye nozinzile kunye namanye amacandelo e-gypsum, enceda ukunciphisa umthamo wamanzi afunekayo kumxube.

Ekubeni amanzi esona sizathu siphambili sokuncipha kwi-plaster eludongeni, ukunciphisa umthamo wamanzi kuya kunceda ukunciphisa ukuncipha.Ukongezwa kwe-cellulose ethers kunceda ukugcina ukufuma kumxube we-stucco, ngaloo ndlela kuncitshiswe ukushwabana okupheleleyo kwe-stucco eludongeni.

Yandisa umanyano kunye nokuguquguquka

I-ether ye-cellulose inokwandisa ukunamathela kunye nokuguquguquka kwe-plaster eludongeni.I-cellulose ethers yandisa ukudibanisa ngokubanzi komxube we-gypsum ngokwenza umxube ozinzile kunye no-homogeneous.Ubukho be-cellulose ether benza kwakhona umxube we-plaster uguquguquke, ukunciphisa umngcipheko wokuqhekeka kunye nezinye iziphene.Ukongeza, ii-ethers ze-cellulose zinika i-elasticity ethile kwi-plastered eludongeni, izenza zikwazi ukumelana nempembelelo.

Ukuphucula ukuxhathisa kwe-sag

I-Sagging yingxaki eqhelekileyo edibana nayo ngexesha lokwakhiwa kwe-plasters eludongeni, ngakumbi kwiindawo ezithe nkqo.Ukongeza i-cellulose ether kumxube we-stucco kunokuphucula ukuxhathisa kwe-sag kunye nokwenza i-stucco izinze ngakumbi ngexesha lokwakha.I-cellulose ethers zenza umxube ofanayo, ozinzileyo onceda ukuthintela udaka olusuka eludongeni.Le propati yenza ukuba i-plaster ixhathise ngakumbi ekuqhekekeni kunye nezinye iziphene ezibangelwa kukudilika.

Ukuphucula ukuxhathisa kwamanzi

I-cellulose ethers inokuphucula ukunganyangeki kwamanzi kwiiplates zodonga.Ekubeni i-cellulose ether yenza i-homogeneous kunye nomxube ozinzile ngamanzi, ithintela amanzi ukuba angangeni kwi-plaster.Le propati yenza udaka oludongeni lukwazi ukumelana namanzi, oluyimfuneko kwimigangatho evezwe emanzini, njengendawo yokuhlambela kunye namakhitshi.

ukunciphisa ixesha lokumisa

Ubukho be-cellulose ethers kwimixube yodaka eludongeni nako kunokunciphisa ixesha lokumisa udaka.Ekubeni i-cellulose ether ilibazisa ukunyuswa kwamanzi kwi-gypsum, iyancipha inkqubo yokomisa, ivumela i-gypsum ukuba yome kwizinga elilawulwayo.Ukunciphisa ixesha lokumisa kunenzuzo, ngakumbi kwiindawo ezifumileyo apho udaka lunokuthatha ixesha elide ukuba lome.

ukuququmbela

Ukuqukumbela, i-cellulose ethers zizongezo ezibalulekileyo kwiifom ze-plaster yodonga.Iphucula ukusebenza, ukunamathela okumanzi, ukudibanisa, ukuguquguquka, ukuxhathisa kwe-sag, ukuxhathisa kwamanzi kunye nexesha lokumisa i-plasters eludongeni.Ukusetyenziswa kwe-cellulose ethers ekubunjweni kodaka eludongeni sisisombululo esingabizi kakhulu kwimingeni emininzi edibana nayo ngexesha lokufakwa kwe-plaster eludongeni.Njengoko ishishini lokwakha liqhubeka likhula, ukusetyenziswa kwe-cellulose ethers ekubunjweni kwe-plaster yodonga kulindeleke ukuba kwandiswe ngenxa yeepropati zabo ezizodwa kunye neenzuzo.
