I-cellulose ethers yiklasi yezixhobo zepolymer ezithathwe kwi-cellulose yendalo. Emva kokuguqulwa kweekhemikhali, zineempawu ezintle ezifana nokunyibilika kakuhle kwamanzi, ukutyeba, kunye neempawu zokwenza ifilimu. Ngokukodwa ziquka i-methyl cellulose (MC), i-hydroxypropyl methyl cellulose (HPMC), i-hydroxyethyl cellulose (HEC), njl.
1. Isityebi sodaka lwesamente
I-cellulose ethers isetyenziswa ngokubanzi njengezinto ezityebisayo zodaka lwesamente ekwakhiweni. Ukongeza umlinganiselo ofanelekileyo we-cellulose ether kwi-samente udaka kunokuphucula ukubambelela kunye nokusebenza kokwakhiwa komdaka, ngelixa ukhusela udaka ekuqhekekeni kunye nomgubo wokuwa. Iyakwazi ukugcina amanzi ngokufunxa umswakama, ukwenzela ukuba udaka luqina ngokulinganayo ngexesha lenkqubo yokuqina, ukunciphisa ingxaki yokuqhekeka okubangelwa ukomisa i-shrinkage. Ukongeza, i-cellulose ethers inokunyusa iplastiki yodaka, iphucule ukwakhiwa kwayo kunye nokusebenza.
2. Iarhente yokugcina amanzi
Kwimeko yokushisa eyomileyo okanye ephezulu, umswakama wezinto ezisekelwe kwi-samente uphuphuma ngokukhawuleza, onokukhokelela ngokulula ekulahlekeni komswakama ogqithiseleyo kwaye uchaphazele ukuchithwa kwesamente okuqhelekileyo. I-ether ye-cellulose ineempawu ezilungileyo zokugcina amanzi. Iyakwazi ukugcina umswakama owaneleyo kwi-samente yodaka, izinto ezisekelwe kwi-gypsum, ukwandisa ixesha le-hydration, ukuqinisekisa ukuba i-samente, i-gypsum kunye nezinye izinto ze-cementitious zigcwele i-hydrated ngokupheleleyo, kwaye emva koko ziphucula amandla kunye nokubambelela. Olu kugcinwa kwamanzi lufanelekile ngokukodwa kwiindawo zokwakha ezomileyo kunye nesantya esiphezulu somoya, ukunciphisa iintanda kunye nokwandisa ubomi benkonzo yezinto.
3. Ukuphuculwa komsebenzi wokwakha
Umphumo wokuqina we-cellulose ether nawo unceda ekuphuculeni ukwakhiwa kodaka kunye ne-putty. Izinto ezine-cellulose ether zinokusasazwa ngokutyibilikayo, zinciphise ukudodobala, kwaye ziququzelele ukusebenza. Ngokukodwa xa ukwakhiwa kwimigangatho ethe nkqo, imiphezulu kunye nemithambeka, izinto aziyi kutyibilika ngokulula, nto leyo enceda ukuphumeza umaleko otyebileyo wokugquma, ukunciphisa ubunzima bokwakha nokuphucula umgangatho weprojekthi. Ngelo xesha, i-lubricating effect ye-cellulose ether yenza ukuba kube lula ukusebenzisa izinto eziphathekayo kunye nokunciphisa ukuchasana komsebenzi wezandla.
4. Ukuxhathisa i-crack
I-ether ye-cellulose inokunciphisa i-shrinkage cracks ebangelwa ukulahlekelwa kwamanzi ngexesha lenkqubo yokunyanga. Ukugcinwa kwayo kwamanzi kunye nemiphumo yokuqina kunceda izinto zibe nzima ngokulinganayo, zigweme uxinzelelo lwangaphakathi olubangelwa ukunqongophala kwamanzi asekuhlaleni, kunye nokuthintela ngokufanelekileyo ukuqhekeka. Ukongeza, i-cellulose ether inokwandisa amandla okuqina kunye namandla acinezelayo ezinto eziphathekayo, ngaloo ndlela iphucula ukuxhathisa kokuqhekeka, kwaye ilungele ukwakhiwa ngeemfuno eziphezulu ezifana nokutyabeka ngaphakathi kunye nodonga lwangaphandle.
5. Ukudibanisa okuphuculweyo
I-ether ye-cellulose inokuphucula kakhulu ukusebenza kokubambisana kwezinto zokwakha. Kwizicelo ezifuna ukudibanisa okuphezulu, njengama-adhesives tile kunye ne-interface agents, i-cellulose ether iphucula ukudibanisa kunye nokubambelela kwizinto eziphathekayo, ukuvumela ukuba izinto zihambelane kakuhle ne-substrate, ukuphucula ngokufanelekileyo ukusebenza kokubambisana. Oku kubaluleke ngokukhethekileyo kulwakhiwo olufana nodonga lwe-plastering kunye ne-tile bonding, enokunciphisa umngcipheko wokuwa kunye nokuqinisekisa ukuzinza kunye nokuqina kwezinto.
6. I-Antifreeze kunye namandla oxinzelelo
Xa kwakhiwa kwiindawo zasebusika okanye ezibandayo, izinto ezisekelwe kwi-cement kunye ne-cellulose ether eyongeziweyo zinokuchasana kangcono nemiphumo yokushisa okuphantsi, ukugcina amandla abo, kunye nokwandisa ixesha lokuqina kwezinto. I-ether ye-cellulose inokugcina kwakhona ukusebenza kwe-cement mortar okanye i-gypsum-based based materials phantsi kweemeko zokushisa eziphantsi, ukuphepha ukulahlekelwa ngumsebenzi wezinto eziphathekayo ngenxa yokushisa okuphantsi. Ukongeza, kunokunceda ukuphucula amandla oxinzelelo lwezixhobo, ukwenza izinto eziqinileyo kwaye ziqine ngexesha lokusetyenziswa.
7. Isetyenziswa kwimigangatho yokuzimela
I-ether ye-cellulose nayo idlala indima ebalulekileyo ekwakhiweni kwemigangatho yokuzimela. Izinto zokuzilinganisa ngokuqhelekileyo zifunwa ukuba zibe ne-fluidity egqwesileyo kunye ne-flatness, ngelixa i-ether ye-cellulose inokuphucula ukugcinwa kwamanzi kunye nokunyuka kwamanzi, inceda izixhobo zomgangatho wokuzimela ukuba zisasazeke ngokukhawuleza nangokulinganayo. Ubukho be-cellulose ether bunokwandisa ixesha lokuvula izinto zomgangatho wokuzimela, okwenza kube lula ukuba abasebenzi bokwakha balungelelanise, ukwenzela ukuba benze umhlaba ococekileyo, ukuphucula ukubonakala kunye nokusebenza.
8. Isebenza kwizinto ezisekelwe kwi-gypsum
I-ether ye-cellulose nayo idlala indima ebalulekileyo kwi-gypsum-based self-leveling materials and putty powders. Inokuphucula ngokufanelekileyo ukugcinwa kwamanzi kunye nokuxhatshazwa kwe-crack ye-gypsum materials, ukuqinisekisa ukuba i-gypsum ayiyi kuncipha kwaye iqhube ngenxa yokulahlekelwa kwamanzi ngexesha lokumisa. Ukongeza, i-ether ye-cellulose inokuphucula iimpawu zokubopha izinto ze-gypsum, ezivumela ukuba zihambelane kakuhle ne-substrate surface kunye nokwandisa ubomi babo benkonzo.
9. Ukuphucula ukuxhathisa kwemozulu kwezixhobo
I-Cellulose ether inokonyusa ukuxhathisa kwemozulu kwemathiriyeli kwezinye iingubo zodonga lwangaphandle kunye nodaka, ibenza bakwazi ukuxhathisa ngcono ukukhukuliseka kwezinto zendalo ezifana nemitha ye-ultraviolet kunye nemvula. Oku kunokunciphisa ngokufanelekileyo ukubola kunye nokuxobulwa kweengubo zodonga zangaphandle, ukugcina ubuhle bomhlaba wokwakha, kunye nokwandisa ubomi bayo benkonzo.
Njengesongezo esibalulekileyo kwizinto zokwakha, i-cellulose ether ineenzuzo ezininzi ezifana nokuqina, ukugcinwa kwamanzi, ukunyuka kwe-viscosity kunye nokumelana nokuqhekeka, okwenza ukuba isetyenziswe ngokubanzi kwizinto zokwakha ezifana nodaka lwesamente, i-tile adhesive, putty, self-leveling floor, njl. Ukongezwa kwe-cellulose ether akugcini nje ukuphucula ukusebenza kokwakhiwa kwezinto, kodwa kuphucula ukunamathela, ukuchasana kwemozulu kunye namandla ezinto eziphathekayo, kunye nokulungelelanisa iimfuno zeendawo ezahlukeneyo zokwakha. Ngoko ke, ukusetyenziswa kwe-cellulose ether kuye kwakhuthaza kakhulu ukuphuhliswa kwezinto zokwakha kunye nokubonelela ngenkxaso yezinto eziphathekayo ezinokwethenjelwa kunye nezizinzileyo kwizakhiwo zanamhlanje.
