Umgubo weQuartz: ucolekile kakhulu, ufanelekile kwiimortar ezifuna amandla aphezulu kunye nokuqina.
I-perlite/i-ceramsite eyandisiweyo: isetyenziswa kakhulu kwiimortars ezilula, ezine-insulation entle yesandi kunye neempawu zokuthintela ubushushu.
3. Izixube
Izixube zekhemikhali zizinto eziphucula ukusebenza kwe-dry-mix mortar, ikakhulu eziquka izinto zokugcina amanzi, izinto ezithintela ubushushu, izinto ezikhawulezisayo, izinto ezithintela ukukhenkceza, njl. Izixube ze-Addiction zinokulungisa ixesha lokuseta, ukunyibilika kwamanzi, ukugcinwa kwamanzi, njl. njl. kwe-mortar, kwaye ziphucule ngakumbi ukusebenza kolwakhiwo kunye nefuthe lokusetyenziswa kwe-mortar.
Isixhobo sokugcina amanzi: sisetyenziselwa ukuphucula ukugcinwa kwamanzi kwi-mortar kunye nokuthintela amanzi ukuba angaphenduki ngokukhawuleza, ngaloo ndlela sandisa ixesha lokwakhiwa kwe-mortar, nto leyo ebaluleke kakhulu, ingakumbi kwiindawo ezinobushushu obuphezulu okanye ezomileyo. Izixhobo zokugcina amanzi eziqhelekileyo ziquka ii-polymers.
Izinto ezithintela ulwakhiwo: zinokulibazisa ixesha lokuseta udaka, zilungele indawo yokwakha enobushushu obuphezulu ukuthintela udaka ukuba luqine ngaphambi kwexesha ngexesha lokwakha.
Izikhawulezisi: zikhawulezisa inkqubo yokuqina kwesamente, ingakumbi kwindawo enobushushu obuphantsi, ezisetyenziswa rhoqo ukukhawulezisa ukusabela kwamanzi kwisamente kunye nokuphucula amandla esamente.
I-Antifreeze: isetyenziswa kwindawo enobushushu obuphantsi ukuthintela ukuba udaka lungaphelelwa ngamandla ngenxa yokubanda.
4. Izongezo
Izithako zokongeza zibhekisa kwizinto zeekhemikhali okanye zendalo ezisetyenziselwa ukuphucula iipropati ezithile ze-dry-mix mortar, zihlala ziquka i-cellulose ether, i-thickener, i-dispersant, njl. I-Cellulose ether, njenge-additive esebenzayo esetyenziswa rhoqo, idlala indima ebalulekileyo kwi-dry-mix mortar.
Indima ye-cellulose ether
I-Cellulose ether ludidi lwee-polymer compounds ezenziwe nge-cellulose ngokuguqulwa kweekhemikhali, ezisetyenziswa kakhulu ekwakheni, kwiingubo, kwiikhemikhali zemihla ngemihla nakwezinye iindawo. Kwi-dry-mix mortar, indima ye-cellulose ether ibonakala kakhulu kwezi zinto zilandelayo:
Ukuphucula ukugcinwa kwamanzi kwisamente
I-cellulose ether inokunyusa ngempumelelo ukugcinwa kwamanzi kwi-mortar kwaye inciphise ukufuma kwamanzi ngokukhawuleza. Ulwakhiwo lwayo lweemolekyuli luqulathe amaqela athanda amanzi, anokwenza amandla aqinileyo okubopha ngeemolekyuli zamanzi, ngaloo ndlela egcina i-mortar imanzi kwaye iphephe ukuqhekeka okanye ubunzima bokwakha obubangelwa kukulahleka kwamanzi ngokukhawuleza.
Ukuphucula i-rheology yesamente
I-cellulose ether inokulungisa ukutyibilika kunye nokunamathela kwe-mortar, okwenza i-mortar ifane ngakumbi kwaye kube lula ukuyisebenzisa ngexesha lokwakha. Iyandisa i-viscosity ye-mortar ngokuyiqinisa, yonyusa ukungahlukaniswa kwayo, ithintela i-mortar ekuhlukaneni ngexesha lokusetyenziswa, kwaye iqinisekisa umgangatho wokwakhiwa kwe-mortar.
Ukuphucula ukunamathela kwesamente
Ifilimu eyenziwe yi-cellulose ether kwi-mortar ine-adhesion entle, enceda ekuphuculeni amandla okubopha phakathi kwe-mortar kunye ne-substrate, ingakumbi kwinkqubo yokwakha yokugquma kunye nokufaka iithayile, inokuphucula ngempumelelo ukusebenza kokubopha kwaye ithintele ukuwa.
Phucula ukumelana nokuqhekeka
Ukusetyenziswa kwe-cellulose ether kunceda ukuphucula ukumelana nokuqhekeka kwe-mortar, ingakumbi kwinkqubo yokomisa, i-cellulose ether inokunciphisa ukuqhekeka okubangelwa kukushwabana ngokwandisa ukuqina kunye namandla okuxinana kwe-mortar.
Ukuphucula ukusebenza kolwakhiwo lwesamente
I-ether yeseliIngalungisa ngokufanelekileyo ixesha lokwakha i-mortar, yandise ixesha lokuvula, kwaye ikwazi ukugcina ukusebenza kakuhle kokwakha kwindawo enobushushu obuphezulu okanye kwindawo eyomileyo. Ukongeza, inokuphucula ukuthamba nokusebenza kwe-mortar kwaye iphucule umgangatho wokwakha.
Njengezixhobo zokwakha ezisebenzayo nezinobuhlobo nokusingqongileyo, ukuqonda kokwakheka kwazo kunye nomlinganiselo wazo kumisela umgangatho wokusebenza kwazo. Njengesongezelelo esibalulekileyo, i-cellulose ether inokuphucula iipropati eziphambili ze-dry-mix mortar, njengokugcinwa kwamanzi, i-rheology, kunye nokunamathela, kwaye idlala indima ebalulekileyo ekuphuculeni ukusebenza kokwakha kunye nomgangatho we-mortar. Njengoko ishishini lokwakha liqhubeka nokwandisa iimfuno zalo zokusebenza kwezinto, ukusetyenziswa kwe-cellulose ether kunye nezinye izongezo ezisebenzayo kwi-dry-mix mortar kuya kuba kubanzi ngakumbi, kubonelela ngendawo enkulu yenkqubela phambili yetekhnoloji yeli shishini.
