I-MHEC kudaka lwesamente oluvuzayo

1. Iimpawu ezisisiseko ze-MHEC

I-MHEC (iMethyl Hydroxyethyl Cellulose)yi-non-ionic cellulose ether enokuqina okuhle, ukugcinwa kwamanzi, ukwakheka kwefilimu kunye nokusebenza okuphuculweyo kolwakhiwo. Kwizixhobo zokwakha ezisekwe kwisamente, i-MHEC inokuphucula kakhulu ukugeleza kwamanzi, ukugcinwa kwamanzi, ukulwa nokwahlukana kunye nokunamathela kwesamente, kwaye isetyenziswa kakhulu kwi-tile adhesive, i-putty powder, i-self-leveling mortar, i-waterproof mortar kunye ne-samente mortar enokugqitha. Ngenxa yempembelelo yayo encinci kwinkqubo yokufunxa isamente kunye nokuhambelana neentlobo ngeentlobo ze-admixtures, i-MHEC ibe yinto ebalulekileyo yokuguqula izinto eziphilayo kwisamente enokugqitha isamente.

2. Iimpawu zesamente enokutyibilika

I-mortar yesamente ephumayo ibhekisa kwi-mortar ekhethekileyo enokungena kwisakhiwo esisisiseko ngesenzo se-capillary, kwaye idla ngokusetyenziswa kwiiprojekthi zokulungisa ulwakhiwo, ukuqinisa kunye nokuthintela amanzi. Olu hlobo lwe-mortar luyimfuneko ukuze lube:

Ukuvuleka kakuhle: ukukwazi ukungena kwiimbobo ezincinci zomaleko wesiseko nokuphucula uxinano lwezinto ezisisiseko;

Ukutyibilika okuphezulu: ukuhamba kakuhle kunye nokungena kwamanzi ngaphandle kokopha kakhulu kunye nokuqhekeka;

Ukunamathela okuqinileyo kunye nokuqina: qinisekisa ukubopha okuqinileyo nezinto ezisisiseko kwaye kudlala indima yokuqinisa nokukhusela ulwakhiwo ixesha elide;

Ukugcinwa kwamanzi okuphakathi: kunciphisa ukulahleka kwamanzi ngokukhawuleza ngexesha lokwakha kwaye uqinisekise ukuba isamente inamanzi aneleyo.

Indima ye-MHEC igxile kakhulu ekuphuculeni ukuhamba kwamanzi, ukugcinwa kwamanzi kunye nokusebenza kolwakhiwo lwe-mortar, ngelixa iphucula ngokungathanga ngqo isiphumo sokungena.

3. Impembelelo ye-MHEC ekusebenzeni kwesamente enokutyibilika

3.1. Phucula ukugcinwa kwamanzi kwaye ukhuthaze ubunzulu bokungena kwamanzi

I-mormeable mortar kufuneka igcine ulungelelwano olufanelekileyo kunye nokufuma ngaphambi kokuba ingene kwi-capillary pores yomaleko osisiseko. I-MHEC inokugcinwa kwamanzi okugqwesileyo, okunokunciphisa ukufuma ngokukhawuleza kwamanzi asimahla kunye nokufunxwa zizinto ezisisiseko ngexesha lenkqubo yokwakha i-mortar, kwandise ixesha lokungena kwe-mortar, kwaye kwandise ubunzulu bokungena. Ukongeza, ukusasazwa kwamanzi okufanayo kukwanceda ekufumaneni amanzi apheleleyo kwi-samente kwinqanaba lokugqibela, okuphucula uxinano kunye nokuqina.

3.2. Ukuphucula ukutyibilika kwamanzi kunye nokusebenza kolwakhiwo

I-MHEC ingayilungisa i-rheological properties ye-permeable cement mortar, ukuze ikwazi ukugcina ulwelo oluhle lokwakha phantsi kweemeko eziphantsi zomlinganiselo wamanzi nesamente. Ukongezwa kwe-MHEC okufanelekileyo kunokunciphisa ukopha kunye nokwahlulwa kwe-mortar, kwaye kuqinisekiswe ukuba i-slurry ingena ngokulinganayo kwiimbobo ezincinci ze-substrate. Kwi-mortar epermeable ekufuneka igalelwe okanye itshizwe, i-MHEC inokuphucula ukusebenza kokupompa kunye nokulinganisa, okwenza i-mortar ibe lula ukuyakha.

3.3. Phucula ukunamathelana phakathi kwesamente kunye nesiseko

Ngenxa yeempawu zokwenza ifilimu ze-MHEC, ifilimu eguquguqukayo yendalo inokwenziwa kwindawo yokudibanisa ngexesha lenkqubo yokuqina kwe-mortar, nto leyo ephucula ukuluma kunye nokunamathelana koomatshini phakathi kwe-mortar kunye ne-substrate. Esi siphumo sokuguqula i-interface sinceda ukuthintela i-mortar ukuba ingasuki kwi-substrate kwaye siphucula ukuqina komgangatho wokulungisa onokuthi ungene.

3.4. Ukuphucula ukumelana nokuqhekeka kunye nolawulo lokuncipha

Ngenxa yokwanda koxinano lwangaphakathi, i-mormeable mortar idla ngokuqhekeka xa iqina. Isiphumo sokugcina amanzi se-MHEC sinokucothisa izinga lokuncipha kwe-mortar, senze i-samente hydration yanele, kwaye sinciphise amathuba okuncipha kwe-plastic cracks. Kwangaxeshanye, iipropati zokwenza ifilimu ze-MHEC zinika i-mortar ukuguquguquka okuthile, nto leyo ephucula ukumelana nokuqhekeka kunye nokuqina kwayo.

3.5. Ukulibazisa ixesha lokuqala lokuseta kuyanceda ekwakheni

I-MHEC inefuthe elincinci lokulibazisa kwinkqubo yokufunxa isamente, nto leyo enceda ukwandisa ixesha lokusebenza kwesamente. Kwiiprojekthi zokulungisa ezifuna ukungena ngokupheleleyo, ixesha elide lokwakha lenza kube lula ukuba udaka lungene kumaleko osisiseko, nto leyo ephucula isiphumo sokulungisa kunye nokuzinza komgangatho.

3.6. Ukuphucula ukusebenza kokungangeni kwamanzi kunye nokusebenza kokungangeni manzi

Kwisigqubuthelo esiqinileyo esingena emanzini, ekubeni i-MHEC iphucula uxinano kunye nokudibanisa kwesigqubuthelo, ulwakhiwo lwaso lwe-capillary lufana ngakumbi, i-porosity iyancitshiswa, kwaye amandla okungangeni kwamanzi aphucuke kakhulu. Kwisigqubuthelo sokuthintela amanzi phantsi komhlaba, ulwelo lwemijelo, i-reservoir kunye nezinye iiprojekthi, isigqubuthelo sokuthintela amanzi esiguqulweyo se-MHEC sinokuthintela ngokufanelekileyo ukufuduka komswakama kwaye siphucule isiphumo sokuthintela amanzi.

4. Ubungakanani bokongeza kunye neendlela zokuzikhusela zokusetyenziswa

Isixa esicetyiswayo sokongeza: ngokubanzi yi-0.2% ukuya kwi-0.6% yobunzima bezinto ezisetyenziswa kwisamente, ekufuneka zilungiswe ngokwesilinganiso samanzi nesamente, ukunyibilika kwesamente kunye nenkqubo yokwakha.

Kuphephe ukongeza okugqithisileyo: Umthamo we-MHEC ogqithisileyo unokukhokelela ekuqineni kakhulu kwe-mortar, ukuncipha kokungena kwamanzi, kwaye unokulibazisa ukujiya kwesamente okugqithisileyo.

Ukuhambelana nezinye izinto ezidityanisiweyo: Kwizigqubuthelo ezityibilikayo eziqulethe izinto zokunciphisa amanzi, izinto ezithintela umoya okanye izinto zokwandisa, idosi efanelekileyo ye-MHEC kufuneka imiselwe ngovavanyo ukuqinisekisa ukusebenza ngokuhambelana.

Kwisigqubuthelo sesamente esingena emanzini, i-MHEC iphucula kakhulu ubunzulu bokungena, ukunamathela, ukumelana nokuqhekeka kunye nokuqina kwesigqubuthelo ngokusebenzisa iimpawu zayo zokugcina amanzi, ukuqina, ukwakha ifilimu kunye nokulungiswa kwe-rheological. Kwangaxeshanye, iphucula ukusebenza kolwakhiwo, yandisa ixesha lokwakha, kwaye iphucula umgangatho uwonke weeprojekthi zokulungisa nokukhusela. Ukukhetha okufanelekileyo kunye nokulawula ubungakanani bokongezaI-MHEC yeyona nto iphambili ekufezekiseni ukusebenza okuphezulu kwesamente enokutyibilika.
