Ukusetyenziswa kweHydroxyethyl Methyl Cellulose kwiSpray Mortar

I-Hydroxyethyl Methyl Cellulose (HEMC)yi-cellulose ether enyibilikayo emanzini engeyiyo ionic enokuqina okugqwesileyo, ukugcinwa kwamanzi, ukuthambisa kunye neempawu zokwenza ifilimu. Isetyenziswa kakhulu kwizixhobo zokwakha, iipeyinti, iikhemikhali zemihla ngemihla nakwezinye iinkalo. Kwiminyaka yakutshanje, ngophuhliso lwemizi-mveliso yokwakha kunye noomatshini bokwakha, i-spray mortar iye yathatha indawo yokwakha yendabuko yokuplasta ngesandla kwaye yaba luhlobo olutsha lwendlela yokwakha esebenza kakuhle neyinobuhlobo nokusingqongileyo. Ukusetyenziswa kwe-HEMC kwi-spray mortar kuye kwaphucula kakhulu ukusebenza kokwakha kunye nomgangatho wemveliso egqityiweyo ye-mortar, kwaye yenye yezona zinto zibalulekileyo kule nkalo.

1. Isishwankathelo seSpray Mortar

I-spray mortar yi-mortar exutyiweyo eyakhiwe ngezixhobo zokutshiza, kubandakanya i-plastering mortar, i-thermal insulation mortar, i-self-leveling mortar kunye nezinye iintlobo. Xa kuthelekiswa nokwakhiwa kwendabuko ngesandla, i-spray mortar ineenzuzo zesantya sokwakha esikhawulezayo, amandla aphantsi okusebenza, umgangatho wokwakha ozinzileyo, kwaye ifanelekile kwimisebenzi emikhulu. Nangona kunjalo, ngenxa yenkqubo yokutshiza ekhawulezayo neqhubekayo, iimfuno eziphezulu zibekwe ekusebenzeni kakuhle, ukunamathela kunye nokugcinwa kwamanzi kwe-mortar.

2. Iimpawu zokusebenza ze-HEMC

I-hydroxyethyl methylcellulose inamaqela asebenzayo e-hydroxyethyl kunye ne-methoxy, nto leyo eyinika ezi mpawu zilandelayo zibalaseleyo:

Ukunyibilika kwamanzi okugqwesileyo kunye nokuzinza: I-HEMC inyibilika ngokukhawuleza emanzini abandayo ukuze yenze isisombululo esicacileyo okanye esikhanyayo esiqinileyo, esifanelekileyo kwiinkqubo ezahlukeneyo zedaka ezixutywe nodaka olomileyo.

Ukugcinwa kwamanzi ngendlela efanelekileyo: Ulwakhiwo lwayo lweemolekyuli lunokuwuvala ngokufanelekileyo umswakama, luthintele umswakama ukuba ungatshi ngokukhawuleza, kwaye luphucule ukutyeba kunye nokunamathela kwesamente ngexesha lokwakha.

Yomeleza ukunamathela kunye nokungatsali: I-HEMC inika amandla afanelekileyo okubopha kunye nokuthamba ukuthintela ukutsali kodaka emva kokutshiza.

Phucula ukusebenza kolwakhiwo: Yenza i-mortar ibe bushelelezi ngexesha lokutshiza, ukupompa kunye nokulinganisa, kwaye uphucule ukusebenza kakuhle kolwakhiwo.

Izinzile kubushushu, i-asidi kunye ne-alkali: Ifanelekile kwiimeko ezahlukeneyo zendalo ukuqinisekisa ukusebenza okuzinzileyo kwedaka.

3. Indima ethile ye-HEMC kwi-spray mortar

3.1. Ukuphucula iipropati ze-rheological zokwakha

Ukusebenza kakuhle kwe-spray mortar kufuna ukuba ibe nokutyibilika okuhle kunye ne-thixotropy ezinzileyo. I-HEMC inokulungisa ukuhambelana kwe-mortar, okwenza kube lula ukuyipompa nokutshiza. Kwangaxeshanye, inokuthi iqine ngokukhawuleza emva kokutshiza eludongeni, iphucule ukusebenza kokungatyibiliki, kwaye iqinisekise ukugqunywa okufanayo kwe-mortar kunye nobukhulu bokwakha obuhambelanayo.

3.2. Phucula ukugcinwa kwamanzi kwaye wandise ixesha lokuvula

Ngexesha lenkqubo yokutshiza, amanzi kulula ukuwakhupha ngokukhawuleza, ingakumbi phantsi kobushushu obuphezulu okanye iimeko zomoya, nto leyo enokubangela ukuba i-mortar iqhekeke okanye i-bonding engalunganga. Ukusebenza kakuhle kwe-HEMC kokugcina amanzi kuyalibazisa ukulahleka kwamanzi, kuqinisekisa ukuba i-samente kunye nezinye izinto ezisebenzisa i-samente zimanzi ngokupheleleyo, kwaye kuphucula amandla e-bonding phakathi kwe-mortar kunye nesiseko. Kwangaxeshanye, ukwandisa ixesha lokuvula kunceda ekulinganisweni okanye ekugqityweni okulandelayo, kwaye kuphucula ukuguquguquka kolwakhiwo.

3.3. Ukuphucula ukuthintela ukugoba kunye nokubopha

Xa kwakhiwa kwiindawo ezithe nkqo okanye iindonga eziphakamileyo, ukuba i-mortar iyanyibilika kakhulu, kulula ukugoba, nto leyo echaphazela inkangeleko kunye nolawulo lobukhulu. I-HEMC yonyusa i-viscosity kunye nokuhlangana ukuze i-mortar ibe ne-thixotropy elungileyo, oko kukuthi, inokuguquguquka okuhle xa iphantsi koxinzelelo (ukupompa okanye ukutshiza), ibuyisela ngokukhawuleza ukuqina xa imile, inamathela ngokuqinileyo eludongeni, kwaye ithintela ngempumelelo ukugoba.

3.4. Phucula uzinzo lwesamente

I-HEMC ingazinzisa ukusasazeka kwezinto ezisebenzisa isamente kunye nee-aggregates kwinkqubo yesamente, ithintele ukwahlulwahlulwa kunye nokuphuma kwamanzi, iqinisekise ukufana komxube wesamente, kwaye iphucule umgangatho wolwakhiwo ngokubanzi.

4. Idosi ye-HEMC kunye nokusetyenziswa kwayo

Ubungakanani obucetyiswayo bokongeza kwi-spray mortar budla ngokuba yi-0.2% ukuya kwi-0.6%, kuxhomekeke kwifomyula, injongo kunye nokusebenza okufunekayo kwe-mortar. I-HEMC yongezwa kwi-mortar eyomileyo ngendlela ye-powder eyomileyo, ixutywe ngokulinganayo nezinye izinto ezikrwada, ize emva koko ixutywe namanzi ukuze isetyenziswe. Inonyibiliko oluhle kakhulu, kulula ukuyisasaza, ayivelisi i-agglomeration, kwaye ilungele imveliso yemizi-mveliso kunye nokusetyenziswa kwindawo.

5. Umzekelo wesiphumo sesicelo

Ukusetyenziswa kwe-HEMC kwi-plastering yangaphandle yodonga olutshizayo kunokunyusa kakhulu ubukhulu bodonga kunye nokukwazi ukuxhoma uludaka lwe-mortar, kwaye kunciphise ukulahleka komhlaba wokwakha. Kwi-mortar yokushisa, i-HEMC iphucula amandla okubopha phakathi kwezinto kunye nomaleko wesiseko, iqinisekisa uzinzo kunye nokuqina kwenkqubo yokushisa. Ingxelo yokwenyani yeprojekthi ibonisa ukuba i-mortar yokutshiza ene-HEMC eyongeziweyo ilula ukuyakha, isiphumo sithambile kwaye sithambile, kwaye izinga lokuphinda ulwakhiwo liyancipha.

Njenge-cellulose ether esebenza kakuhle kakhulu,i-hydroxyethyl methylcellulose idlala indima ebalulekileyo ekuqineni nasekugcinweni kwamanzi, ukuzinzisa kunye noncedo lokwakha kwi-spray mortar, okuphucula kakhulu ukusebenza kokutshiza ngoomatshini kunye nomgangatho wemveliso egqityiweyo ye-mortar. Ngokukhuthazwa kokwenziwa ngokuzenzekelayo kwesakhiwo kunye nokwakhiwa okuluhlaza, ukusetyenziswa kwe-HEMC kwicandelo le-premixed mortar kuya kuba kubanzi ngakumbi, kube negalelo elibalulekileyo ekuphuculeni iteknoloji yezixhobo zokwakha.
