I-Methyl hydroxyethyl cellulose (MHEC) ekusetyenzisweni kwedaka

I-Methyl hydroxyethyl cellulose (MHEC)yi-non-ionic cellulose ether derivative enokuqina okugqwesileyo, ukugcinwa kwamanzi, ukwenza ifilimu kunye nokusebenza ngokulula. Idlala indima ebaluleke kakhulu kwiinkqubo zanamhlanje zokwakha i-dry-mixed mortar. Isetyenziswa kakhulu kwiimveliso ezahlukeneyo ezifana ne-masonry mortar, i-plaster mortar, i-tile adhesive, i-cement self-leveling kunye ne-thermal insulation mortar, enokuphucula kakhulu ukusebenza kwe-mortar kwaye iphucule umgangatho kunye nokusebenza kakuhle kolwakhiwo.

1. Ukuphucula ukugcinwa kwamanzi kwisamente

Omnye wemisebenzi ebalaseleyo ye-MHEC kukusebenza kwayo okuhle kakhulu kokugcina amanzi. Ngexesha lenkqubo yokwakha i-mortar, izinto eziqinisayo ezifana nesamente okanye i-gypsum zifuna inkxaso eyaneleyo yamanzi kwi-reaction yokuqina, ngelixa umaleko osisiseko uhlala unomngxuma onamandla wamanzi, oya kuthi ufunxe amanzi ngokukhawuleza kwi-mortar, nto leyo ebangela ukulahleka kwamanzi kwangoko kwi-mortar kwaye ichaphazele inkqubela phambili ye-hydration reaction. I-MHEC yenza isakhiwo se-mesh esisasazwe ngokulinganayo esinemilinganiselo emithathu kwi-mortar, ivala ngokuqinileyo umswakama, ithintela umswakama ukuba ungafunxwa ngumaleko osisiseko okanye umoya, kwaye ngaloo ndlela igcina ukusebenza kwe-mortar ixesha elide. Esi siphumo sokugcina amanzi sibalulekile ekwandiseni ixesha lokwakha, ukuphucula uphuhliso lwamandla kunye nokuthintela ukuqhekeka.

2. Ukuphucula ukusebenza kolwakhiwo kunye nemvakalelo yokusebenza

I-MHEC, njengesithambisi esisebenzayo, inokuphucula kakhulu ukuhambelana kunye neempawu ze-thixotropic ze-mortar, okwenza i-mortar ibe nokusebenza kakuhle kokwakha. Ngexesha lenkqubo yokwakha efana nokuplasta kunye nokupeyinta, i-mortar equlethe i-MHEC inomphezulu ogudileyo, kulula ukuyisasaza, ayinamatheli kwimela, kwaye ineempawu ezilungileyo zokulwa nokugoba. Ingakumbi xa yakhiwa kwiindawo ezithe nkqo, i-mortar ayilula ukuyityibiliza ezantsi, nto leyo elula ukulawula ubukhulu be-coating kunye nokuphucula ukusebenza kakuhle kokwakha. Ukongeza, iimpawu zokuthambisa ze-MHEC zonyusa ukusebenza kwe-mortar, zinciphisa ukusebenza ngokomzimba kwabasebenzi bokwakha, kwaye ziphucule intuthuzelo yokwakha.

3. Ukuqinisa ukubopha

Nangona i-MHEC ngokwayo ingeyonto yokuncamathelisa, inceda isamente okanye ezinye izinto zokuncamathelisa ukuba zidibane ngokupheleleyo nesiseko ngokuphucula ukumanzi kwesamente kunye nokwandisa ixesha lokuvula, ngaloo ndlela iphucula ngokungathanga ngqo amandla okunamathela kwesamente kunye nesiseko, izitena, iithayile kunye nezinye izinto. Ingakumbi kwi-adhesives zethayile kunye nee-interface agents, i-MHEC inokwenza ifilimu yokuncamathelisa efanayo neqhubekayo, evumela ukuba izinto zinamathele ngokuqinileyo kwisiseko, ziphucule ukusebenza kwesamente kunye nokuzinza kwenkqubo iyonke.

4. Lawula indlela ebekwe ngayo kunye nexesha lokuqina kwesamente

I-MHEC ingayilibazisa inkqubo yokufunxa isamente okanye i-gypsum kwi-mortar, ngaloo ndlela yandisa ixesha lokuseta i-mortar. Oku kuluncedo kakhulu ekwakheni kwindawo enobushushu obuphezulu okanye kwindawo eyomileyo, kwaye kunokuthintela iingxaki zokwakha ezibangelwa kukuseta ngokukhawuleza kakhulu, njengokuqhekeka komphezulu kunye nokubopha okubuthathaka. Ngokulungisa ngokufanelekileyo ubungakanani be-MHEC eyongeziweyo, ixesha elisebenzayo le-mortar linokulawulwa ngokuchanekileyo ukuhlangabezana neemfuno zokwakha zeenkqubo ezahlukeneyo.

5. Ukuphucula ukumelana nokuqhekeka kunye nokuqina kwesamente

Ekubeni i-MHEC iphucula ukugcinwa kwamanzi kunye nokuguquguquka kwe-mortar, inciphisa ukushwabana kunye nokulahleka kwamanzi kwangoko, inokuthintela ngempumelelo ukwenzeka kwee-cracks zokuncipha kwaye iphucule ukumelana nee-cracks kunye nokuqina kwe-mortar ngexesha lokusetyenziswa ixesha elide. Kwiinkqubo zokukhusela udonga lwangaphandle okanye kwizakhiwo ezimelana nenyikima, le ntsebenzo ibaluleke kakhulu kwaye inegalelo kuzinzo kunye nobomi besakhiwo.

6. Ukuhambelana okuqinileyo nenkqubo yodaka

I-MHEC, njenge-polymer engeyiyo i-ionic, ihambelana kakuhle nezinto ezahlukeneyo zesamente ezifana nesamente, ilayimu, i-gypsum, kunye nezinye izongezo (ezifana nomgubo we-latex ophinda unyibilike, i-water reducer, i-antifreeze agent, njl.njl.). Oku kuvumela ukuba isetyenziswe ngokulula kwiinkqubo ezahlukeneyo zesamente ezisebenzayo, ayichaphazeleki ziikhemikhali okanye ziingxabano zokusebenza, kwaye ibonelela ngenkululeko ephezulu kwiifomyula zesamente ezomileyo.

7. Ukuziqhelanisa nozinzo kunye nokusingqongileyo

I-MHEC iyakwazi ukuziqhelanisa ne-pH kunye nobushushu, izinzile kakuhle kwiindawo ezine-asidi, ezingathathi cala okanye ezibuthathaka kwi-alkaline, kwaye inokugcina ukuhambelana okuhle kunye nokugcinwa kwamanzi nakwiindawo zokwakha ezinobushushu obuphezulu. Olu phawu luvumela ukuba isetyenziswe kakhulu kwiinkqubo ze-mortar kwiindawo ezahlukeneyo zemozulu, ingakumbi xa kwakhiwa ehlotyeni.

I-Methyl hydroxyethyl cellulose (MHEC) idlala utshintsho olunemiba emininziindima kwi-mortar. Ibonelela ngesisombululo esithembekileyo, esisebenzayo nesilawulekayo sokwakha ngokuphucula ukugcinwa kwamanzi, ukuphucula ukusebenza, ukuphucula ukunamathela, ukulungisa ixesha lokuseta kunye nokuphucula ukumelana nokuqhekeka kunye nokuqina. Ngophuhliso olukhawulezileyo lwezixhobo zokwakha eziluhlaza kunye ne-mortars ezixutyiweyo kwangaphambili, indima ye-MHEC iya kuba yinto ebalaseleyo nangakumbi, ibe sisixhobo esincedisayo nesibalulekileyo kwi-formulations ze-mortar ezisebenza kakuhle.
