Iyintoni indima ye-methylcellulose ekubopheni udaka kunye ne-plasters?

I-Methylcellulose idlala indima ebalulekileyo ekwenziweni kodaka kunye ne-plasters, ngakumbi ekwandiseni iimpawu zabo zokubopha. Kwizicelo zokwakha, iidaka kunye neeplasta zizinto ezisisiseko ezisetyenziselwa iinjongo ezahlukeneyo, kubandakanywa ukwakhiwa kwe-masonry, i-stuccoing, i-rendering, kunye nemisebenzi yokulungisa. Ukongezwa kwe-methylcellulose kule mixube kusebenzela imisebenzi emininzi ebalulekileyo, igalelo ekusebenzeni ngokubanzi kunye nokuqina kwemveliso yokugqibela.

1. Ugcino lwamanzi:

I-Methylcellulose isebenza njenge-ejenti yokugcina amanzi kwi-mortars kunye ne-plasters. Ubume bayo be-hydrophilic buvumela ukuba ifunxe kwaye igcine amanzi ngaphakathi komxube, ukuthintela ukomisa kwangaphambi kwexesha. Eli xesha lide le-hydration libalulekile ekuqinisekiseni ukuphiliswa ngokufanelekileyo kunye nokubambelela kwizinto eziphathekayo kwi-substrate. Ngokugcina umgangatho womswakama ophezulu, i-methylcellulose iphakamisa ukusebenza, ivumela ukusetyenziswa lula kunye nokuguqulwa kodaka okanye udaka.

2. Ukuncamathela okuPhuculweyo:

Ukubambelela okusebenzayo kubalulekile ekusebenzeni kwexesha elide lodaka kunye neeplaster. I-Methylcellulose isebenza njenge-binder, yenza i-cohesive bond phakathi kwamaqhekeza ngamnye omxube kunye ne-substrate surface. Le bhondi ibalulekile ekuthinteleni i-delamination kunye nokuqinisekisa imfezeko yesakhiwo semathiriyeli esetyenzisiweyo. Ukongezelela, ubukho be-methylcellulose bukhuthaza ukunamathela okungcono kwii-substrates ezahlukeneyo, kubandakanywa ikhonkrithi, i-masonry, i-wood, kunye nesinyithi, ngaloo ndlela iphucula ukuguquguquka kunye nokusebenza.

3. UThungelwano olwandisiweyo:

Ukongeza ekuphuculeni ukubambelela, i-methylcellulose igalelo ekudibaneni kodaka kunye ne-plasters. Isebenza njenge-binder, idibanisa iinqununu ezidibeneyo kunye nezinye iinxalenye zomxube. Olu bumbano luphucula amandla onke kunye nokuzinza kwezinto eziphathekayo, ukunciphisa amathuba okuqhekeka, ukuncipha, kunye nezinye iindlela zokuguqulwa. Ngenxa yoko, i-methylcellulose inceda ekudaleni udaka oluqinileyo kunye noluhlala luhleli kunye ne-plasters ezikwaziyo ukumelana namandla angaphandle kunye neemeko zokusingqongileyo.

4. Ukumelana neCrack:

Ukuqhekeka ngumba oqhelekileyo ohlangatyezwana nodaka kunye nokufakwa kwe-plaster, ehlala ibangelwa yimiba efana nokushwabana, ukwanda kwe-thermal, kunye nentshukumo yesakhiwo. I-Methylcellulose inceda ukunciphisa le ngxaki ngokuphucula ukuguquguquka kunye nokuqina kwezinto. Ubukho bayo buvumela udaka okanye i-plaster ukuba ifake ukunyakaza okuncinci kunye noxinzelelo ngaphandle kwe-fracturing, ngaloo ndlela inciphisa umngcipheko wokuqhaqha kunye nokuphucula ukuqina okupheleleyo kwesakhiwo.

5. Ukusebenza kunye nokuSasazeka:

Ukongezwa kwe-methylcellulose kwandisa ukusebenza kunye nokusasazeka kweedaka kunye ne-plasters. Ukukwazi kwayo ukugcina amanzi kunye nokuthambisa umxube kwenza kube lula ukusetyenziswa kunye nokugubungela okungcono, okukhokelela ekugqityweni okufanayo kunye nobuhle obuhle. Ngaphezu koko, ukusebenza okuphuculweyo kuvumela ukubunjwa lula, ukubumba, kunye neenkcukacha, okwenza amagcisa afezekise ukuthungwa okufunwayo kunye neepateni ngokuchanekileyo ngakumbi.

6. Ukuncitshiswa kokuSagging kunye nokuThobeka:

Ukuthoba kunye nokudilika ziingxaki eziqhelekileyo ezihlangabezana nazo ngexesha lokusetyenziswa kodaka oluthe nkqo okanye oluphezulu kunye neeplasta. I-Methylcellulose inceda ukujongana nale miba ngokunyusa iimpawu ze-thixotropic zomxube. Thixotropy ibhekiselele ekuguquleni ukuguqulwa kwezinto ezibonakalayo ukusuka kwimeko efana nejeli ukuya kwimeko yamanzi amaninzi phantsi koxinzelelo lwe-shear, evumela ukuba ihambe ngokulula ngexesha lesicelo kodwa iphinde iphinde iphinde iphinde iphinde isetyenziswe. Ngokuphucula i-thixotropy, i-methylcellulose inceda ukukhusela i-sagging kunye ne-slumping, iqinisekisa ukufana kunye nokunyaniseka koluhlu olusetyenzisiweyo.

7. Ukuhambelana kokusingqongileyo:

I-Methylcellulose ithathwa njengobungane bokusingqongileyo kwaye ayinayo inetyhefu, eyenza ifaneleke ukusetyenziswa kwizicelo zokwakha apho ukuzinza kunye nokhuseleko kuyinkxalabo enkulu. Ngokungafaniyo nezinye izibophelelo zokwenziwa, i-methylcellulose i-biodegradable kwaye ayikhuphi iikhemikhali eziyingozi kwindalo esingqongileyo. Ukusetyenziswa kwayo kulungelelaniswa nemigaqo yokwakhiwa okuluhlaza kunye nezenzo zokwakha ezizinzileyo, ezinegalelo kumgangatho ophilileyo womoya wangaphakathi kunye nokunciphisa impembelelo yokusingqongileyo.

8. Ukuhambelana nezongezo:

I-Methylcellulose iyahambelana noluhlu olubanzi lwezongezo ezisetyenziswa ngokuqhelekileyo kwi-mortar kunye ne-plaster formulations, njenge-air-entraining agents, i-accelerators, i-retarders, kunye ne-pigments. Ukuguquguquka kwayo kuvumela ukufakwa kwezongezo ezahlukeneyo ukuguqula iimpawu ezithile zomxube, njengokubeka ixesha, uphuhliso lwamandla, umbala, kunye nokuthungwa. Oku kuhambelana kwandisa ukuguquguquka kunye nokwenza ngokwezifiso ukwakhiwa kodaka kunye nodaka, okwenza izisombululo ezilungiselelwe ukuhlangabezana neemfuno ezithile zeprojekthi kunye neendlela zokusebenza.

I-methylcellulose idlala indima eninzi ekuphuculeni ukusebenza, ukuqina, kunye nokusebenza kodaka kunye ne-plasters. Ukukwazi kwayo ukugcina amanzi, ukuphucula ukunamathela kunye nokudibanisa, ukuxhathisa ukuqhekeka, ukuphucula ukusebenza, ukunciphisa ukuthoba, kunye nokuqinisekisa ukuhambelana kokusingqongileyo kuyenza ibe yinto eyongezelelweyo ebalulekileyo kwizicelo zokwakha. Ngokubandakanya i-methylcellulose kwi-mortar kunye ne-plaster formulations, abakhi kunye neengcibi banokufikelela kwiziphumo eziphezulu, ukuqinisekisa ixesha elide kunye nokunyaniseka kwezakhiwo zabo.
