Udaka olufuthwe ngomshini, olubuye lwaziwe ngokuthi i-jetted mortar, kuyindlela yokufafaza udaka endaweni ethile usebenzisa umshini. Le nqubo isetshenziswa ekwakhiweni kwezindonga zesakhiwo, phansi kanye nophahla. Inqubo idinga ukusetshenziswa kwe-hydroxypropyl methylcellulose ether (HPMC) njengengxenye eyisisekelo yodaka lwesifutho. I-HPMC inezinzuzo ezimbalwa eziyenza ibe isithasiselo esihle kakhulu semfucumfucu eyimishini.
Ukusebenza kwe-HPMC ku-Mechanical Spraying Mortar
I-HPMC iphuma ku-cellulose encibilika emanzini. Inezici eziningana eziyingqayizivele ezihlanganisa ukuqina, ukugcinwa kwamanzi kanye nokubopha. Lezi zakhiwo zenza i-HPMC ibe isithasiselo esibalulekile sodaka olufuthwe ngomshini. Izakhiwo zokujiya nokugcina amanzi zibalulekile ekufakweni kodaka olufuthwe ngomshini. Baqinisekisa ukuthi udaka luhlala ndawonye, lunamathela phezulu, futhi alubalekeli.
I-HPMC ingasetshenziswa futhi njengesihlanganisi sodaka lokufafaza ngomshini. Kuyasiza ukuhlanganisa izinhlayiya zodaka ndawonye, ukuqinisekisa ukunamathela okuqinile phezulu. Lesi sici sibalulekile njengoba siqinisekisa ukuthi udaka lwesifutho lunomphumela ohlala isikhathi eside futhi lusivimbela ukuthi singaxebuka phezulu.
Izinzuzo ze-HPMC zodaka lokufafaza ngomshini
1. Thuthukisa ukusebenza
Ukwengeza i-HPMC kudaka lokufafaza ngomshini kungathuthukisa ukusebenza kwayo. Ithuthukisa ikhono lodaka ukuze linamathele phezulu, livimbele ukulahlekelwa kwalo. Lesi sici sibaluleke kakhulu uma usebenza ezindongeni noma ophahleni ukuze uqinisekise ukuthi udaka alusuki.
2. Khulisa ukugcinwa kwamanzi
I-HPMC inomthamo omuhle kakhulu wokugcina amanzi, okuyindawo ebalulekile yodaka lwemishini yokufutha. Ngisho nalapho kwakhiwa, udaka luhlala lunamanzi, okwenza umkhiqizo wokugcina uqine futhi uhlale isikhathi eside.
3. Ukunamathela okungcono
I-HPMC isebenza njengesibophezelo, ibopha izinhlayiya zodaka olufuthwe ngomshini ndawonye ukuze kunamathele kangcono. Lesi sakhiwo siqinisekisa ukuthi udaka lunamathela phezulu ukuze lube nomphumela ohlala isikhathi eside futhi luvimbele ukuthi lungaxebuki phezulu.
4. Yehlisa ukuqhekeka
Uma yengezwe kumishini yokufutha yodaka, i-HPMC inciphisa ubungozi bokuqhekeka. Yakha isibopho esiqinile ngaphakathi kodaka, okuvumela ukuba imelane nokucindezela kanye nemithwalo engaziwa. Lokhu kubangela umkhiqizo oqinile ongeke uqhekeke noma uxebuke ngemva kokufakwa.
Ukusetshenziswa kwe-HPMC ku-Mechanical Spraying Mortar
Ukuze uthole imiphumela emihle kakhulu ngodaka lwezifutho ezisebenza ngomshini, inani elifanele kanye nekhwalithi ye-HPMC kufanele kusetshenziswe. I-HPMC kufanele ixutshwe kahle nezinto ezomile ukuze kuqinisekiswe ukusatshalaliswa okufanayo. Inani le-HPMC elidingekayo lincike ezintweni ezifana nohlobo lwendawo kanye nezici zokusebenza ezifiselekayo zodaka.
Izisimende ezifakwe ngomshini ziye zashintsha imboni yezokwakha, futhi ukwengezwa kwe-HPMC kuletha izinzuzo eziningana ezihlanganisa ukusebenza okuthuthukisiwe, ukukhushulwa kokugcinwa kwamanzi, ukunamathela okungcono kanye nokuncipha kokuqhekeka. I-HPMC isiyingxenye ebalulekile yodaka lokufafaza ngomshini, futhi umthelela wayo omuhle awunakubukelwa phansi. Ukusetshenziswa ngendlela efanele kwe-HPMC kumishini yokufutha yodaka kungaqinisekisa umkhiqizo oqinile, ohlala isikhathi eside ohlangabezana namazinga okwakha aqinile.
