I-Methyl Hydroxyethyl Cellulose (MHEC)yi-nonionic cellulose ether esetyenziswa kakhulu kwiikhemikhali zokwakha. Ibonisa ukutyeba okugqwesileyo, ukugcinwa kwamanzi, ukwakheka kwefilimu, ukubopha, kunye nokusasaza, okwenza ukuba ibe sisongezelelo esibalulekileyo kwiimortars ezixutywe nomileyo, izincamathelisi zeethayile, iipowders ze-putty, izinto ezisekwe kwi-gypsum, kunye neenkqubo zokugquma.
1. Ulawulo lokuqina kunye ne-Rheology
Kwimveliso yesamente kunye ne-gypsum, i-MHEC iqina ngokwenza iibhondi ze-hydrogen kunye neemolekyuli zamanzi, inyusa i-viscosity yesisombululo. Le propati iphucula ngokufanelekileyo ukutyibilika nokusebenza kakuhle kwe-slurry, ithintela ukwahlulwa okanye ukopha ngexesha lokuxuba nokufaka. Kwizinto zokuncamathelisa iithayile kunye neempuphu ze-putty, ukongezwa kwe-MHEC kwenza kube lula ukufaka izinto, kudala umphezulu ofanayo ngakumbi, kwaye kuphucula ukusebenza kakuhle kokwakha.
2. Ukugcinwa Kwamanzi Nokomiswa Kade
Enye yezona mpawu zibalaseleyo ze-MHEC kukugcina kwayo amanzi kakuhle. Ngexesha lokwakha i-samente mortar kunye neemveliso ze-gypsum, ukufuma ngokukhawuleza kwamanzi kunokukhokelela ekubeni angabi namandla ngokwaneleyo, aqhekeke, okanye anciphe ukunamathela. I-MHEC yenza ifilimu ye-molecular efanayo kwinkqubo, inciphisa ukufuma kwamanzi kwaye iqinisekise ukufuma okupheleleyo kwesamente kunye nokuqina okupheleleyo kwe-gypsum, ngaloo ndlela yonyusa amandla okugqibela kunye nokuqina kwezinto. Le propati ibaluleke kakhulu kwiindawo zokwakha ezishushu nezomileyo.
3. Ukuphuculwa Kokusebenza
I-MHEC iphucula kakhulu ukusebenza kakuhle kweekhemikhali zokwakha. Iphucula ukutyeba kwesamente, iyenza ithambe ngexesha lokukrwela nokutsalwa kwesamente, inciphisa ukumelana nokwakha kunye nobunzima bomsebenzi. Ngaphezu koko, ngenxa yeempawu zayo ze-thixotropic, i-MHEC igcina i-viscosity ephezulu xa imile ngexesha lokwakha, ithintela ukugoba okanye ukuvuza. Xa iphantsi kwamandla angaphandle, i-viscosity yayo iyancipha, iququzelela ukusetyenziswa kunye nokusasazwa. Olu hlengahlengiso lwe-rheological luphucula kakhulu amava okwakha.
4. Ukuphucula Amandla eBond
Kwizinto zokuncamathelisa iithayile, iinkqubo zokugquma udonga lwangaphandle, kunye neemortar ezizilinganisayo, i-MHEC iphucula ukugcinwa kwamanzi kunye nokufuma kwemortar, iphucula ukunamathela kwayo kwisiseko nakwizinto ezijongene nayo. Ukongeza i-MHEC kwi-adhesive yethayile kuqinisekisa ixesha elaneleyo lokuvula iithayile ngexesha lokufakwa, okuthintela ukugoba okanye ukuwa ngenxa yokulahleka kwamanzi ngokukhawuleza. Ngaphezu koko, impendulo efanayo yokufuma ngaphakathi kwemortar iphucula kakhulu amandla ebhondi, iqinisekisa ukuthembeka kwesakhiwo kunye nokhuseleko lwesakhiwo.
5. Ukuphucula Ukuguquguquka kweMozulu kunye noMgangatho woMphezulu
I-MHEC inceda ekwakheni isakhiwo somphezulu esifanayo nesixineneyo kwiinkqubo zedaka kunye nepeyinti, inciphisa ngempumelelo amathuba okuqhekeka. Kwi-putty powder kunye neengubo zodonga zangaphandle, i-MHEC iphucula iipropati zokwenza ifilimu kunye nokuthamba, okubangela umphezulu wodonga oluthambileyo noluncinci kwaye ibonelela ngesiseko esihle kakhulu seengubo ezilandelayo. Ngaphezu koko, iphucula ukumelana nokuqandisa kunye nokumelana nemozulu kwenkqubo, iqinisekisa ukusebenza okuzinzileyo kwiimeko ezahlukeneyo zemozulu.
6. Imizekelo yokusetyenziswa
Izincamathelisi zeTayile kunye neeGrouts: I-MHEC iqinisekisa ukugcinwa kwamanzi kunye nokusebenza kakuhle kwezincamathelisi zetayile, yandisa ubomi bazo bokusebenza kwaye iphucula amandla eebhondi.
IiPowders zePutty kunye nezixhobo zokuLinganisa udonga: I-MHEC iphucula ukuguda kunye nokugcinwa kwamanzi ngexesha lokukrwela, ithintela ukuqhekeka kunye nokuqhekeka. Iimveliso ezisekwe kwiGypsum: Ezifana neplasta yokuzilinganisa yegypsum kunye ne-gypsum putty: I-MHEC iphucula ukusebenza kunye namandla, ithintela ukulahleka kwamanzi ngokukhawuleza.
I-mortar yokukhusela udonga lwangaphandle: Iphucula ukusebenza kakuhle kwe-mortar, ukugcinwa kwamanzi, kunye nokumelana nokuwa, iqinisekisa ukunamathela okuqinileyo kwenkqubo.
Udaka oluxutywe nodaka: Lusetyenziswa kakhulu kwidaka lokwakha, i-plaster mortar, kunye ne-repair mortar, ukuqinisekisa ukusebenza kakuhle kwedaka.

7. Uthelekiso nezinye ii-Ether zeCellulose
Kwizicelo zeekhemikhali zokwakha, i-MHEC idla ngokuthelekiswa ne-HPMC (hydroxypropyl methylcellulose). Nangona ezi zimbini zineempawu ezifanayo, i-MHEC inika ukunyibilika okungcono kunye nokusebenza kakuhle kweendleko, okwenza ukuba ifaneleke ngakumbi kwizicelo ezinobunzima beendleko. I-HPMC, kwelinye icala, ibonisa ukumelana okuphezulu kobushushu kunye nokuqina. Ke ngoko, kwiifomyula zokwenyani, i-MHEC okanye i-HPMC, okanye indibaniselwano yazo zombini, zihlala zikhethwa ngokusekelwe kwiimfuno zokwakha kunye neengcamango zoqoqosho ukuze kufezekiswe iziphumo ezilungileyo.
Njengesithako esibalulekileyo sekhemikhali yokwakha,I-MHEC, ngeempawu zayo ezibanzi zokutyeba, ukugcinwa kwamanzi, ukusebenziseka ngcono, ukunamathela okuphuculweyo, kunye nokumelana nemozulu okuphuculweyo, isetyenzisiwe kakhulu kwiintlobo ngeentlobo zezicelo, kubandakanya izincamathelisi zethayile, iipowder ze-putty, iimveliso ze-gypsum, ii-insulation mortars, kunye neengubo. Ayigcini nje ngokuphucula iimpawu ezibonakalayo zezinto zokwakha kodwa ikwaphucula ukusebenza kakuhle kolwakhiwo kunye nomgangatho wokugqibela weprojekthi. Njengoko izixhobo zokwakha ziqhubeka ziguqukela kwizixhobo eziluhlaza, ezinobuhlobo nokusingqongileyo, kunye nokusebenza okuphezulu, amathuba okusetyenziswa kwe-MHEC aya kwanda, kwaye indawo yayo ebalulekileyo kwishishini leekhemikhali zokwakha iya kuqhubeka nokuqina.
