I-mortar ezenzela umlinganiselo wayo inokuxhomekeka kubunzima bayo ukuze yenze isiseko esithe tyaba, esigudileyo nesiqinileyo kwisiseko sokubeka okanye ukubopha ezinye izinto, kwaye kwangaxeshanye inokwenza ulwakhiwo olukhulu nolusebenzayo. Ke ngoko, ukutyibilika okuphezulu yinto ebaluleke kakhulu kwi-mortar ezenzela umlinganiselo. Ukongeza, kufuneka ibe nokugcinwa kwamanzi kunye namandla okubopha, ingabi nanto yakwenza nokwahlulwa kwamanzi, kwaye ibe neempawu zokuthintela ubushushu kunye nokunyuka kobushushu obuphantsi.
Ngokubanzi, i-self-leveling mortar ifuna ukutyibilika okuhle, kodwa ukutyibilika kwe-cement paste yokwenyani kudla ngokuba yi-10-12cm kuphela; i-cellulose ether sisongezelelo esiphambili se-ready-mixed mortar, nangona isixa sokongeza siphantsi kakhulu, sinokuphucula kakhulu ukusebenza kwe-Mortar, sinokuphucula ukufana, ukusebenza, ukusebenza kwe-bonding kunye nokusebenza kokugcina amanzi kwe-mortar.
1: Ukunyibilika kodaka
I-Cellulose ether inefuthe elibalulekileyo ekugcinweni kwamanzi, ukuhambelana kunye nokusebenza kolwakhiwo lwe-self-leveling mortar. Ingakumbi njenge-self-leveling mortar, ukutyibilika yenye yezona mpawu ziphambili zokuvavanya ukusebenza kwe-self-leveling. Phantsi kwengcamango yokuqinisekisa ukwakheka okuqhelekileyo kwe-mortar, ukutyibilika kwe-mortar kunokulungiswa ngokutshintsha ubungakanani be-cellulose ether. Nangona kunjalo, ukuba idosi iphezulu kakhulu, ukutyibilika kwe-mortar kuya kuncitshiswa, ngoko ke idosi ye-cellulose ether kufuneka ilawulwe ngaphakathi koluhlu olufanelekileyo.
2: Ukugcinwa kwamanzi odaka
Ukugcinwa kwamanzi kwi-mortar sisalathisi esibalulekileyo sokulinganisa ukuzinza kwezinto zangaphakathi ze-mortar esandula ukuxutywa yesamente. Ukuze kuphunyezwe ngokupheleleyo ukusabela kokufuma kwezinto zejeli, ubungakanani obufanelekileyo be-cellulose ether bunokugcina ukufuma kwi-mortar ixesha elide. Ngokubanzi, izinga lokugcina amanzi kwi-slurry liyanda ngokwanda komxholo we-cellulose ether. Isiphumo sokugcina amanzi kwi-cellulose ether sinokuthintela i-substrate ekufunxeni amanzi amaninzi ngokukhawuleza, kwaye sithintele ukufuma kwamanzi, ukuqinisekisa ukuba indawo ye-slurry inika amanzi aneleyo okufumisa isamente. Ukongeza, i-viscosity ye-cellulose ether nayo inempembelelo enkulu ekugcinweni kwamanzi kwi-mortar. Okukhona i-viscosity iphezulu, kokukhona i-retention yamanzi ingcono. Ngokubanzi, i-cellulose ether ene-viscosity ye-400mpa.s isetyenziswa kakhulu kwi-self-leveling mortar, enokuphucula ukusebenza kwe-leveling kwe-mortar kwaye yonyuse ubuncinci be-mortar.
3: Ixesha lokuseta i-mortar
I-Cellulose ether inefuthe elithile lokulibazisa kwi-mortar. Njengoko umxholo we-cellulose ether unyuka, ixesha lokubeka i-mortar liyanda. Isiphumo sokulibazisa se-cellulose ether kwi-cement paste sixhomekeke kakhulu kwinqanaba lokutshintshwa kweqela le-alkyl, kwaye asinanto yakwenza nobunzima bayo beemolekyuli. Okukhona umgangatho wokutshintshwa kwe-alkyl uncinci, kokukhona umxholo we-hydroxyl umkhulu, kwaye kokukhona umphumo wokulibazisa ubonakala ngakumbi. Kwaye okukhona umxholo we-cellulose ether uphezulu, kokukhona isiphumo sokulibazisa somaleko wefilimu yomxube ekufakweni kwesamente kwangoko, ngoko ke umphumo wokulibazisa nawo ubonakala ngakumbi.
4: Amandla oxinzelelo lwe-mortar kunye namandla okuguquguquka
Ngokwesiqhelo, amandla yenye yezona zikhokelo zibalulekileyo zovavanyo lwempembelelo yokuphilisa kwezinto ezisekwe kwisamente kumxube. Xa umxholo we-cellulose ether usanda, amandla okucinezela kunye namandla okugoba kwesamente aya kuncipha.
5: Amandla okubopha i-mortar
I-Cellulose ether inefuthe elikhulu ekusebenzeni kwe-bonding ye-mortar. I-Cellulose ether yenza ifilimu ye-polymer enesiphumo sokutywina phakathi kwamasuntswana e-samente hydration kwinkqubo yesigaba solwelo, ekhuthaza amanzi amaninzi kwifilimu ye-polymer ngaphandle kwamasuntswana e-samente, okunceda ukufuma okupheleleyo kwe-samente, ngaloo ndlela kuphucula amandla e-bond ye-paste emva kokuqina. Kwangaxeshanye, isixa esifanelekileyo se-cellulose ether siphucula i-plasticity kunye nokuguquguquka kwe-mortar, kunciphisa ukuqina kwendawo yokutshintsha phakathi kwe-mortar kunye ne-substrate interface, kwaye kunciphisa amandla okutyibilika phakathi kwamasuntswana. Ngandlela thile, isiphumo se-bonding phakathi kwe-mortar kunye ne-substrate siyaphuculwa. Ukongeza, ngenxa yokubakho kwe-cellulose ether kwi-samente paste, indawo ekhethekileyo yokutshintsha kwe-interface kunye nomaleko we-interface zenziwa phakathi kwamasuntswana e-mortar kunye nemveliso ye-hydration. Olu maleko we-interface lwenza indawo yokutshintsha ye-interface ibe bhetyebhetye kwaye ingaqini kangako, ukuze i-mortar ibe namandla e-bond aqinileyo.
