I-Methylhydroxyethylcellulose (MHEC) iyinhlanganisela ye-polymer esetshenziswa kabanzi ezintweni zokwakha futhi inezinzuzo ezibalulekile ekusetshenzisweni kwe-putty. Nazi izinzuzo eziyinhloko ze-methylhydroxyethylcellulose ekusetshenzisweni kwe-putty:
1. Thuthukisa ukusebenza kokwakhiwa
1.1 Thuthukisa ukugcinwa kwamanzi
I-Methyl hydroxyethyl cellulose inokugcinwa kwamanzi okuhle kakhulu, okusiza ukwandisa isikhathi esivulekile se-putty, okuvumela ofake isicelo isikhathi esengeziwe sokwenza izinguquko kanye nokuthinta. Ukwengeza, ukugcinwa kwamanzi okuhle kuvimbela i-putty ukuba yome ngokushesha ngemva kokufaka isicelo, kunciphisa ingozi yokuqhekeka nokuchotshozwa.
1.2 Thuthukisa ukuguquguquka nokusebenza kahle kwesakhiwo
I-MHEC ingathuthukisa kakhulu i-fluidity ye-putty, ikwenze kube lula ukuyisebenzisa nokusabalalisa. Lokhu kunganciphisa izimpawu zamabhulashi namabhamuza phakathi nenqubo yokwakha futhi kuthuthukise ikhwalithi yokwakha kanye nobuhle be-putty.
1.3 Nikeza ukunamathela okuhle
I-MHEC ingathuthukisa ukunamathela phakathi kwe-putty ne-substrate, iqinisekise ukuzinza nokuqina kwengubo. Lokhu kubaluleke kakhulu ekwakhiweni ezindaweni eziyinkimbinkimbi noma ezishisa kakhulu, njengoba kuvimbela ungqimba lwe-putty ukuthi lungaxebuka futhi luxebuke.
2. Thuthukisa izici ezibonakalayo ze-putty
2.1 Thuthukisa ukumelana nokuqhekeka
Ngenxa yokugcinwa kwamanzi kanye nomphumela we-plasticizing we-MHEC, i-putty ingancipha ngokulinganayo ngesikhathi senqubo yokumisa, ukunciphisa amathuba okomisa nokuqhekeka. Ukuguquguquka kwe-putty kuyathuthukiswa, kuyivumela ukuthi ivumelane kangcono nokuguqulwa okuncane ku-substrate ngaphandle kokuqhekeka.
2.2 Thuthukisa ukumelana nokugqokwa
I-MHEC ithuthukisa ubulukhuni nokuqina kwe-putty, okwenza ubuso bayo bukwazi ukumelana nokugqoka. Lokhu kubaluleke kakhulu ezindongeni ezisetshenziswa njalo noma ezingaphansi kokungqubuzana, okusiza ukwandisa impilo yodonga.
2.3 Thuthukisa ukumelana nesimo sezulu
I-MHEC ku-putty ingathuthukisa ukumelana kwayo nesimo sezulu, ukuyivumela ukuthi igcine ukusebenza okuzinzile ngaphansi kwezimo zezulu ezahlukene. Kungakhathaliseki ukuthi izinga lokushisa eliphezulu, izinga lokushisa eliphansi noma imvelo enomswakama, i-putty ingagcina izakhiwo zayo ezinhle kakhulu zomzimba futhi ayithinteki kalula izinguquko zemvelo.
3. Lungiselela ukuzinza kwamakhemikhali we-putty
3.1 Thuthukisa ukumelana ne-alkali
I-Methyl hydroxyethyl cellulose ingathuthukisa ukumelana ne-alkali kwe-putty futhi ivimbele ukuwohloka kokusebenza okubangelwa ukuguguleka kwezinto ze-alkaline. Lokhu kuqinisekisa ukuthi i-putty igcina ukusebenza kwayo okuhle nokubukeka kwayo lapho ithintana nezinto ezine-alkaline njengama-substrates ayi-cementitious.
3.2 Ukuthuthukisa izakhiwo ze-antibacterial kanye ne-antifungal
I-MHEC inemiphumela ethile ye-antibacterial kanye ne-anti-mildew, engavimbela ukukhula kwamagciwane kanye nesikhunta futhi ivimbele amabala okukhunta kanye nephunga elimnandi ukuthi lingaveli endaweni ye-putty. Lokhu kubaluleke kakhulu ezindaweni ezinomswakama noma ezinomswakama ukusiza ukugcina izindonga zihlanzekile futhi zihlanzekile.
4. Ukuvikelwa kwemvelo kanye nezinzuzo zezomnotho
4.1 Izici zokuvikela imvelo
I-Methyl hydroxyethyl cellulose iyimpahla eluhlaza futhi evumelana nemvelo engenabuthi futhi engenabungozi emzimbeni womuntu nasemvelweni. Ukusetshenziswa kwayo kunganciphisa ukusetshenziswa kwezinye izithasiselo zamakhemikhali eziyingozi futhi kunciphise ukungcoliswa kwemvelo ngesikhathi sokwakhiwa.
4.2 Yehlisa izindleko
Nakuba izindleko zokuqala ze-MHEC zingase zibe phezulu, ukusebenza kwayo ngempumelelo ku-putty kunganciphisa inani lezinto ezisetshenzisiwe kanye nesikhathi sokufaka isicelo, ngaleyo ndlela kunciphise izindleko zokwakha zizonke. Impilo ende yesevisi kanye nezidingo zokunakekelwa okuncane nakho kuholela ezinzuzweni zezomnotho zesikhathi eside.
5. Uhlu olubanzi lwezinhlelo zokusebenza
I-Methyl hydroxyethyl cellulose ayifanele kuphela i-putty yangaphakathi yodonga, kodwa futhi isetshenziswa kabanzi ezintweni zokwakha ezihlukahlukene ezifana ne-wall putty yangaphandle, i-anti-cracking mortar, nodaka oluzilinganisa. Ukuguquguquka kwayo kanye nezakhiwo ezinhle kakhulu kuyenza ibe isithasiselo esibalulekile ekwakhiweni kwezakhiwo zesimanje.
I-Methylhydroxyethylcellulose inezinzuzo ezibalulekile ekusetshenzisweni kwe-putty. Ngokuthuthukisa ukugcinwa kwamanzi, uketshezi lokwakha, ukunamathela kanye nezakhiwo zomzimba, i-MHEC ingathuthukisa kakhulu ukusebenza kokwakhiwa kanye nokusebenzisa umphumela we-putty. Ngaphezu kwalokho, izakhiwo zayo ezihambisana nemvelo kanye nezinzuzo zezomnotho nazo ziyenza ibe isithasiselo sezinto zokwakha ezifanele. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, amathemba okufaka isicelo e-MHEC ku-putty azoba banzi.
