I-Hydroxyethyl Methyl Cellulose (i-HEMC, i-Hydroxyethyl Methyl Cellulose) iyingxenye ebalulekile ye-cellulose ether esetshenziswa kakhulu ezintweni zokwakha, ikakhulukazi kuma-adhesives we-tile. Ukwengezwa kwe-HEMC kungathuthukisa kakhulu ukusebenza kwe-adhesive.
1. Izidingo zokusebenza ze-adhesive tile
I-adhesive ye-tile yinto ekhethekile yokunamathela esetshenziselwa ukulungisa amathayili e-ceramic kuma-substrates. Izakhiwo eziyisisekelo ze-adhesive tile zihlanganisa amandla aphezulu okubopha, ukumelana okuhle kokushelela, ukwakhiwa kalula nokuqina. Njengoba izidingo zabantu zekhwalithi yokwakha ziqhubeka nokwanda, izinamathiselo zamathayili kudingeka zibe nokugcinwa kwamanzi okungcono, zandise isikhathi sokuvula, zithuthukise amandla okubopha, futhi zikwazi ukuzivumelanisa nokwakhiwa ngaphansi kwezimo ezihlukene zokushisa nomswakama.
2. Indima ye-HEMC ku-adhesive tile
Ukwengezwa kwe-HEMC kunomthelela omkhulu ekuguqulweni kwezinamathelisi zamathayili e-ceramic, ikakhulukazi kulezi zici ezilandelayo:
a. Khulisa ukugcinwa kwamanzi
I-HEMC inezindawo ezinhle kakhulu zokugcina amanzi. Ukwengeza i-HEMC ku-adhesive tile kungathuthukisa kakhulu ukugcinwa kwamanzi kwe-adhesive, kuvimbele amanzi ukuthi ahwamuke ngokushesha, futhi kuqinisekise ukugeleza okwanele kukasimende nezinye izinto. Lokhu akusizi nje ukuthuthukisa amandla okubopha okunamathiselwe kwe-tile, kodwa futhi kwandisa isikhathi sokuvula, okwenza ukulungiswa kwama-tile kube nezimo kakhulu phakathi nenqubo yokwakha. Ukwengeza, ukusebenza kokugcinwa kwamanzi kwe-HEMC kungagwema ngokuphumelelayo ukulahlekelwa kwamanzi ngokushesha ezindaweni ezomile, ngaleyo ndlela kunciphise ukuvela kokuqhekeka okomile, ukuxebuka nezinye izinkinga.
b. Thuthukisa ukusebenza nokumelana nokushelela
Umphumela wokuqina we-HEMC ungakhuphula i-viscosity ye-adhesive, ngaleyo ndlela uthuthukise ukusebenza kwayo kokwakhiwa. Ngokulungisa inani le-HEMC elingeziwe, i-adhesive ingaba ne-thixotropy enhle ngesikhathi senqubo yokwakha, okungukuthi, i-fluidity iyanda ngaphansi kwesenzo samandla angaphandle, futhi ibuyele ngokushesha esimweni esiphezulu se-viscosity ngemva kokumiswa kwamandla angaphandle. Lesi sici asisizi nje ukuthuthukisa ukuzinza kwamathayili e-ceramic ngesikhathi sokubekwa, kodwa futhi sinciphisa ukuvela kokushelela futhi siqinisekisa ukushelela nokunemba kokubeka i-ceramic tile.
c. Thuthukisa amandla okubopha
I-HEMC ingathuthukisa amandla esakhiwo sangaphakathi se-adhesive, ngaleyo ndlela ithuthukise umphumela wayo wokubopha ku-substrate kanye ne-ceramic tile surface. Ikakhulukazi ezindaweni zokwakha ezinamazinga okushisa aphezulu noma umswakama ophezulu, i-HEMC ingasiza i-adhesive ukugcina ukusebenza okuzinzile kokubopha. Lokhu kungenxa yokuthi i-HEMC ingakwazi ukuzinzisa uhlelo phakathi nenqubo yokwakha, iqinisekise ukuthi ukusabela kwe-hydration kasimende nezinye izinto eziyisisekelo kuqhubeka kahle, ngaleyo ndlela kuthuthukisa amandla okubopha nokuqina kwe-adhesive tile.
3. Umthamo we-HEMC kanye nebhalansi yokusebenza
Inani le-HEMC lidlala indima ebalulekile ekusebenzeni kwama-adhesive tile. Ngokuvamile, inani elingeziwe le-HEMC liphakathi kuka-0.1% no-1.0%, elingalungiswa ngokuvumelana nezimo ezihlukahlukene zokwakha kanye nezidingo. Umthamo ophansi kakhulu ungase ubangele ukugcinwa kwamanzi okwanele, kuyilapho umthamo ophezulu kakhulu ungase ubangele uketshezi olubi lwe-adhesive, kuthinte umphumela wokwakha. Ngakho-ke, ekusetshenzisweni okusebenzayo, kuyadingeka ukucabangela ngokucophelela indawo yokwakha, izakhiwo ze-substrate, nezidingo zokugcina zokwakha, futhi ulungise ngokunengqondo inani le-HEMC ukuze kuqinisekiswe ukuthi i-viscosity, isikhathi sokuvula, namandla okunamathela kufinyelela ibhalansi efanelekile.
4. Izinzuzo zohlelo lokusebenza lwe-HEMC
Ukunethezeka kokwakhiwa: Ukusetshenziswa kwe-HEMC kungathuthukisa ukusebenza kokwakhiwa kwezinamathelisi zamathayili e-ceramic, ikakhulukazi endaweni enkulu yokugandaywa kanye nezindawo eziyinkimbinkimbi, okwenza inqubo yokwakha ibe bushelelezi.
Ukuqina: Njengoba i-HEMC ingathuthukisa ukugcinwa kwamanzi namandla okubopha okunamathelayo, isendlalelo sokubopha amathayili ngemva kokwakhiwa sizinzile futhi sihlala isikhathi eside.
Ukuvumelana nezimo zemvelo: Ngaphansi kwezimo ezihlukene zokushisa nomswakama, i-HEMC ingakwazi ukugcina ngokuphumelelayo ukusebenza kokwakhiwa kwe-adhesive futhi ivumelane nokushintsha kwesimo sezulu ezindaweni ezahlukene.
Ukusebenza Kwezindleko: Nakuba izindleko ze-HEMC ziphakeme, ukuthuthukiswa kwayo okuphawulekayo kokusebenza kunganciphisa isidingo sokwakhiwa kwesibili nokugcinwa, ngaleyo ndlela kunciphise izindleko zizonke.
5. Amathemba okuthuthukiswa kwe-HEMC ekufakweni kwe-ceramic tile adhesive
Ngokuthuthuka okuqhubekayo kobuchwepheshe bezinto zokwakha, i-HEMC izosetshenziswa kabanzi kuma-adhesive tile e-ceramic. Ngokuzayo, njengoba izidingo zokusebenza kokuvikelwa kwemvelo nokusebenza kahle kokwakhiwa zikhula, ubuchwepheshe be-HEMC nezinqubo zokukhiqiza zizoqhubeka nokuthuthukiswa ukuze kuhlangatshezwane nezidingo zokusebenza okuphezulu, ukusetshenziswa kwamandla okuphansi kanye nokuvikelwa kwemvelo okuluhlaza. Isibonelo, ukwakheka kwamangqamuzana e-HEMC kungathuthukiswa ngokwengeziwe ukuze kuzuzwe ukugcinwa kwamanzi okuphezulu namandla okubopha, futhi ngisho nezinto ezikhethekile ze-HEMC zingathuthukiswa ezingakwazi ukuzivumelanisa nama-substrates athile noma umswakama ophezulu kanye nezindawo zokushisa eziphansi.
Njengengxenye eyinhloko ekunamatheleni kwamathayili, i-HEMC ithuthukisa kakhulu ukusebenza kwezinamathiselo zamathayili ngokuthuthukisa ukugcinwa kwamanzi, amandla okubopha kanye nokusebenza kokwakha. Ukulungiswa okunengqondo komthamo we-HEMC kungathuthukisa kakhulu ukuqina nomphumela wokubopha we-ceramic tile adhesive, ukuqinisekisa ikhwalithi nokusebenza kahle kokwakhiwa komhlobiso wokwakha. Esikhathini esizayo, ngokuthuthukiswa kobuchwepheshe kanye nezinguquko ezifunwa yimakethe, i-HEMC izosetshenziswa kabanzi ekunamatheleni kwamathayela e-ceramic, inikeze izixazululo ezisebenza kahle futhi ezinobungani bemvelo embonini yezokwakha.
