1. Isingeniso se-hydroxyethyl methylcellulose
I-Hydroxyethyl Methyl Cellulose (HEMC)iyi-ether engeyona i-ionic yamanzi encibilika i-cellulose ekhiqizwa ngokusabela kwamakhemikhali njenge-alkalinization kanye ne-etherification ye-cellulose yemvelo. Inokuqina okuhle kakhulu, ukugcinwa kwamanzi, ukwenza ifilimu, ukuthambisa kanye nezindawo zokubopha futhi isetshenziswa kakhulu ezintweni zokwakha, okokumboza, kwezemithi, ukudla neminye imikhakha. Emkhakheni wokwakha, ikakhulukazi kudaka olomile kanye ne-putty powder, i-HEMC idlala indima ebalulekile.
2. Indima yokuthuthukisa ukuqhubekela phambili
Thuthukisa ukusebenza kokwakha
Phakathi kwezinto zokwakha, i-HEMC inezici ezinhle kakhulu zokuqina futhi ingathuthukisa ngempumelelo i-thixotropy kanye nokumelana ne-sag yezinto. Lesi sici senza ukwakhiwa kube lula. Ikakhulukazi uma usebenzisa ezindaweni eziqondile, okokusebenza akulula ukucwilisa, okwenza kube lula kuma-opharetha ukwakha i-coating efanayo kanye nokwenza ngcono ukusebenza kahle kokwakhiwa.
i-rial ingahlala ifanelekile isikhathi eside ngemuva kokugcotshwa noma ukunyakaziswa. Lokhu kuthenga abasebenzi bokwakha isikhathi esengeziwe sokulungiswa nokulungiswa futhi kuthuthukisa ikhwalithi yokwakha.
3. Indima yokuthuthukisa ukusebenza
Izakhiwo ezinhle kakhulu zokugcina amanzi
Enye yezindawo eziphawuleka kakhulu ze-HEMC ukugcinwa kwayo kahle kwamanzi. Emasimende asekelwe ku-cement noma e-gypsum-based, i-HEMC inganciphisa ngempumelelo ukulahlekelwa kwamanzi futhi iqinisekise ukuthi usimende noma i-gypsum inomswakama owanele ngesikhathi sokusabela kwe-hydration. Lokhu akugcini nje ukuthuthukisa amandla nokubopha kwezinto ezibonakalayo, kodwa futhi kunciphisa ingozi yokuqhekeka nokugoba.
Thuthukisa ukunamathela
Njengoba i-HEMC inezakhiwo ezinhle zokwakha ifilimu, ingenza ifilimu efanayo endaweni yokwakha, ngaleyo ndlela ithuthukise ukunamathela phakathi kwezinto ezibonakalayo kanye ne-substrate. Lesi sakhiwo sibaluleke kakhulu ekusetshenzisweni okufana nokunamathiswa kwamathayili nama-putty, lapho kungathuthukisa kakhulu ukuqina nokuzinza.
Thuthukisa ukumelana neqhwa
Ezindaweni ezibandayo kakhulu, ukumelana nokuncibilika kweqhwa kubaluleke kakhulu. I-HEMC ithuthukisa ukumelana kwesimo sezulu sento ngokuthuthukisa ukusatshalaliswa komswakama ngaphakathi kwempahla futhi yehlise ukushintshwa kwevolumu okubangelwa ukuqhwa nokuncibilika kwamanzi phakathi nomjikelezo wokuqandisa.
4. Izimo ezijwayelekile ezisetshenziswayo
udaka olomile
Ngodaka olomile, i-HEMC ayithuthukisi kuphela ukugcinwa kwamanzi nokusebenza kodaka, kodwa futhi ilungiselela ukusebenza kahle kwezinto, okwenza udaka lube lula ukusabalalisa nokulolonga ngesikhathi sokwakha.
I-tile glue
I-HEMC ingathuthukisa amandla okubopha i-colloid ezintweni ezinamathelayo zamathayela e-ceramic, iqinisekise ukuxhumana okuqinile phakathi kwamathayili e-ceramic nama-substrates, futhi inciphise ukushelela kwezinto ngesikhathi sokwakha.
I-putty powder
Phakathi kwama-putty powders, i-HEMC ingathuthukisa ukushelela kwendawo, ithuthukise ukumelana kwamanzi nokumelana nokuqhekeka kwe-coating, futhi yenze isendlalelo se-putty senze kangcono ekwakhiweni okulandelayo (njengopende we-latex).
IHydroxyethyl methylcellulose isibe isithasiselo esibalulekile nesibalulekile ezintweni zokwakha zesimanje ngenxa yokujiya kwayo okuhle kakhulu, ukugcinwa kwamanzi, ukugcotshwa nezinye izakhiwo. Akuthuthukisi kakhulu kuphela ukucutshungulwa kwezinto zokwakha, kodwa futhi kuthuthukisa ukusebenza nokuqina kwemikhiqizo eqediwe, ilethe ukunethezeka okukhulu kanye nezinzuzo kubasebenzi bokwakha nabasebenzisi. Ngokuthuthuka okuqhubekayo kobuchwepheshe, izinkambu zokufaka izicelo kanye nemiphumela ye-HEMC izokwandiswa, kuhlinzekwe usizo olwengeziwe ekuthuthukisweni kwemboni yezokwakha.
