Yazisa:
I-Methylhydroxyethylcellulose (MHEC) yi-ether ye-cellulose esebenza ngeendlela ezininzi esetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokugcinwa kwamanzi okugqwesileyo kunye neempawu zokubambelela.I-MHEC ivela kwi-cellulose yendalo kwaye ifumene izicelo ekwakhiweni, amayeza, ukutya kunye nezimonyo.
Ubume bekhemikhali kunye neempawu:
I-MHEC yi-methyl-substituted hydroxyethylcellulose derivative kunye nesakhiwo esisodwa se-molecular.I-backbone ye-cellulose ibonelela nge-biodegradability engokwemvelo kunye nokuhambelana nokusingqongileyo, okwenza i-MHEC ibe yinto yokuqala yokukhetha kwizicelo ezininzi.Amaqela e-Hydroxyethyl kunye ne-methyl aphucula ukunyibilika kwayo kwaye atshintshe iimpawu zayo zomzimba kunye neekhemikhali, zinika imisebenzi eyahlukeneyo.
Indlela yokugcina amanzi:
Olunye lweempawu eziphambili ze-MHEC yindlela ebalaseleyo yokugcina amanzi.Kwizinto zokwakha ezifana nodaka kunye neemveliso ezisekelwe kwi-samente, i-MHEC isebenza njenge-arhente yokugcina amanzi, ukukhusela ukulahleka kwamanzi ngokukhawuleza ngexesha lokunyanga.Oku kubalulekile ukugcina inkqubo efanelekileyo, ukuphucula ukunamathela kunye nokuphucula ukusebenza ngokubanzi kwezinto.
I-MHEC ifezekisa ukugcinwa kwamanzi ngeendlela ezininzi:
I-Hydrophilicity: Indalo ye-hydrophilic ye-MHEC yenza ukuba ikwazi ukufunxa kwaye igcine iimolekyuli zamanzi.I-cellulose backbone, kunye ne-hydroxyethyl kunye namaqela e-methyl, yenza isakhiwo esikwazi ukugcina amanzi ngaphakathi kwe-matrix yayo.
Iimpawu zokwenza ifilimu: I-MHEC inokwenza ifilimu encinci, eguquguqukayo xa ihlakazekile emanzini.Ifilimu isebenza njengesithintelo, ukunciphisa ukukhuphuka kwamanzi kunye nokubonelela ngoluhlu olukhuselayo lokugcina umswakama ngaphakathi kwezinto.
Isiphumo sokuqina: Ekubeni i-MHEC idumba emanzini, ibonisa umphumo wokuqina.Oku kwanda kwe-viscosity kuncedisa ekugcinweni kwamanzi okungcono, ukuthintela amanzi ukuba ahlukane nezinto kunye nokugcina umxube we-homogeneous.
Izicelo kulwakhiwo:
Ishishini lokwakha lithembele kakhulu kwi-MHEC kwiipropati zayo zokugcina amanzi.I-MHEC ixhamla udaka, i-grout kunye nezinye izinto ze-cementitious ngokunyusa ukusebenza, ukunciphisa ukuqhekeka kunye nokuphucula ukubambelela.Ukongeza, i-MHEC iququzelela ukumpompa kunye nokutshizwa kwezinto zokwakha, okwenza ukuba ibe yinto eyongezelelweyo ebalulekileyo kwimisebenzi yokwakha yanamhlanje.
Iimpawu zokuncamathelisa:
Ukongeza kokugcinwa kwamanzi, i-MHEC idlala indima ebalulekileyo ekuphuculeni ukunamathela kwiintlobo ezahlukeneyo zezicelo.Iimpawu zayo zokuncamathelisa zixabiseke kakhulu kula mashishini alandelayo:
I-Tile Adhesives: I-MHEC isoloko isetyenziselwa ukunamathela kwi-tile ukunyusa amandla ebhondi phakathi kwe-tile kunye ne-substrate.Yenza iifilimu eziguquguqukayo kwaye iphucule ukusebenza, iqinisekisa ibhondi eyomeleleyo kunye nexesha elide.
Ukunamathisela iphepha lodonga: Kwimveliso yokunamathisela iphepha lodonga, i-MHEC inceda ukudibanisa iphepha lodonga eludongeni.Ikhusela intlama ukuba yome ngaphambi kwexesha kwaye ikhuthaza ubudlelwane obuqinileyo kunye nexesha elide.
IiCompounds ezidibeneyo: I-MHEC isetyenziswe kwiimpawu ezidibeneyo ngenxa yokubopha kwayo kunye neempawu zokuqina.Inceda ukufezekisa ukugqitywa okugudileyo kunye nokunamathela kwizicelo ze-drywall.
ukuququmbela:
I-Methylhydroxyethylcellulose (MHEC) i-faceted cellulose ether kunye nokugcinwa kwamanzi okugqwesileyo kunye neempawu zokubambelela.Ubume bayo obukhethekileyo bemolekyuli, i-hydrophilicity, isakhono sokwenza ifilim kunye nesiphumo sokuqina senza ukuba isetyenziswe ngokubanzi kumashishini ahlukeneyo.Ukususela kwizinto zokwakha ukuya kumayeza kunye nezithambiso, i-MHEC idlala indima ebalulekileyo ekuphuculeni ukusebenza kwemveliso kunye nokuqinisekisa ukusebenza kakuhle.Njengoko amashishini aqhubeka efuna izisombululo ezihambelana nokusingqongileyo kunye nezisebenzayo, i-MHEC iyaqhubeka iyindlela exabisekileyo kunye nezinzileyo kwiintlobo ezahlukeneyo zezicelo.
