I-Methylhydroxyethylcellulose (MHEC) i-ether ye-cellulose ebalulekileyo esetyenziswe ngokubanzi kwishishini lokwakha ngenxa yeempawu zayo ezintle. Isakhiwo esisisiseko se-MHEC kukuqaliswa kwamaqela e-methyl kunye ne-hydroxyethyl kwi-cellulose skeleton, eguqulwa ngamakhemikhali ukuba ibe neempawu ezikhethekileyo, ezifana nokuqina, ukugcinwa kwamanzi, ukunamathela kunye nokubunjwa kwefilimu.
isiphumo sokuqina
I-MHEC inesiphumo esihle sokuqina kwaye inokunyusa kakhulu i-viscosity yodaka kunye neengubo. Ekwakhiweni, i-viscosity yodaka ichaphazela ngokuthe ngqo ukusebenza kwayo yokwakha kunye nesiphumo sokugqibela. Ngokunyusa i-viscosity yodaka, i-MHEC yenza ukuba kungabi lula ukugoba xa isetyenzisiwe kwaye inokugubungela ngokulinganayo udonga, ukuphucula ukusebenza kakuhle kunye nomgangatho. Ukongezelela, ukongeza i-MHEC kwi-coating inokuthintela ukugubungela kunye nokutshiza, ukuqinisekisa ukufana kunye nokuguquguquka kwengubo.
ukugcinwa kwamanzi
Ukugcinwa kwamanzi ngenye yezona zinto zibalulekileyo ze-MHEC kwizinto zokwakha. Ngethuba lenkqubo yokwakha, ukufuma kwi-mortar kunye nekhonkrithi kuncitshiswa ngokukhawuleza ngenxa yokunyuka kwe-evaporation kunye ne-absorption, okubangela ukulahlekelwa kwamandla ezinto eziphathekayo kunye nokuqhekeka. I-MHEC inokugcina ngokufanelekileyo amanzi, yandise ixesha lokumanzisa udaka kunye nekhonkrithi, ikhuthaze i-hydration eyaneleyo ye-samente, kwaye iphucule amandla kunye nokuqina kwezinto. Ngokukodwa kwiindawo eziphakamileyo zokushisa okanye ezomileyo zokwakha, umsebenzi wokugcinwa kwamanzi we-MHEC ubaluleke kakhulu.
ukudibanisa
I-MHEC ikwanazo nezakhiwo ezibalaseleyo zokudibanisa kwaye inokuphucula amandla okudibanisa phakathi kodaka kunye ne-substrate. Kwiimpawu zokubambelela kwi-tile kunye neenkqubo zangaphandle zokugquma iindonga, i-MHEC njengesongezo inokuphucula amandla okuxhamla kwi-adhesive kunye nokukhusela iileyili ekuweni kunye ne-insulation layer from cracking. Ngokusebenzisa i-MHEC ngokufanelekileyo ekuqulunqweni, ukuthembeka kunye nobude bezinto zokwakha kunokuqinisekiswa.
ukwenziwa kwefilimu
I-MHEC ineempawu ezintle zokwenza ifilimu kwaye inokwenza ifilimu yokukhusela efanayo kwindawo. Le filimu ekhuselayo ikhusela umswakama ukuba uphume ngokukhawuleza kwaye unciphise ukuqhekeka kunye nokunciphisa phezu kwezinto eziphathekayo. Kwiingubo zokugquma kwamanzi kunye nezixhobo zokutywinwa, i-filimi-forming effect ye-MHEC inokuphucula ukusebenza kwamanzi kunye nokuqinisekisa umphumo ongenamanzi wesakhiwo. Kwimigangatho yokuzimela, i-MHEC inokuphucula i-smoothness kunye ne-flatness yomgangatho womgangatho kunye nokubonelela ngeziphumo zokuhlobisa eziphezulu.
Eminye imisebenzi
Ukongeza kwezi ndima ziphambili zingentla, i-MHEC inezinye izicelo ezibalulekileyo kwiiprojekthi zokwakha. Ngokomzekelo, ukongeza i-MHEC yokutshiza i-gypsum inokuphucula ukusebenza kokwakhiwa kunye nokuguquguquka komhlaba we-gypsum. Kwi-putty yangaphandle eludongeni, i-MHEC inokuphucula ukuguquguquka kunye nokubambelela kwi-putty kunye nokuthintela ukuqhekeka nokuwa. Ukongeza, i-MHEC ingasetyenziselwa ukuzinzisa ukukhusela i-delamination kunye nemvula yezinto zokwakha ngexesha lokugcinwa, ukuqinisekisa ukuzinza kunye nokufana kwezinto.
Usetyenziso
I-adhesive ye-tile: Ukongeza i-MHEC kwi-adhesive tile inokunyusa ixesha lokuvula kunye nexesha lohlengahlengiso lwe-adhesive tile, ukwenza ukwakhiwa kube lula ngakumbi, ngelixa uphucula amandla okudibanisa kunye nokuthintela iileyile ukuba zingawi.
Inkqubo yokugquma udonga lwangaphandle: I-MHEC njengesongezo inokunyusa ukunamathela kunye nokugcinwa kwamanzi kwi-insulation mortar kunye nokuphucula umgangatho wokwakha kunye nokuqina komgangatho we-insulation layer.
Umgangatho wokuzilinganisa: Ukongeza i-MHEC kwizinto eziphathekayo zomgangatho wokuzimela kunokuphucula umbane kunye nomgangatho ophantsi kwaye uqinisekise ukuguquguquka kunye nobuhle bomgangatho womgangatho.
Ukugquma kwamanzi: Ukusetyenziswa kwe-MHEC kwi-coatproofing waterproofing kungaphucula ifilimu-ukwenza ifilimu kunye nokusebenza kwamanzi okungena kwamanzi kunye nokukhusela ukungena komswakama kunye nomonakalo wezinto eziphathekayo.
I-Methylhydroxyethylcellulose isetyenziswa ngokubanzi kwiiprojekthi zokwakha ngenxa yokuguquguquka kwayo kunye neempawu ezibalaseleyo. Ukususela ekuqinisweni, ukugcinwa kwamanzi, ukudibanisa ukubunjwa kwefilimu, i-MHEC idlala indima ebalulekileyo ekuphuculeni umsebenzi wokwakha kunye nomphumo wokugqibela wezinto zokwakha. Ngokuqhubela phambili okuqhubekayo kwetheknoloji kunye nokujula kophando lwesicelo, amathuba okufaka isicelo se-MHEC kwintsimi yokwakha aya kuba ebanzi.
