ukwazisa
Udaka olomileyo lusetyenziswa kuluhlu olubanzi lwezicelo zokwakha ezibandakanya i-masonry, i-insulation kunye nomgangatho.Kwiminyaka yakutshanje, i-hydroxypropylmethylcellulose (HPMC) iye yaba sisibophelelo esisetyenziswa ngokuqhelekileyo kwiidaka ezomileyo.I-HPMC yipolymer eguquguqukayo enokuthi ifakwe kwimixube yodaka olomileyo ukuphucula ukunamathela, ukugcinwa kwamanzi kunye nokusebenza.Eli nqaku liza kuphonononga iinzuzo zokusebenzisa i-HPMC kudaka olomileyo kwaye kutheni ibe lukhetho lokuqala lwabakhi kunye neekontraki.
Ziziphi ii-HPMCs?
IHydroxypropyl methylcellulose sisilulo seselulosi esiveliswe kwizinto zendalo zepolymer.HPMC kakhulu ukunyibilika emanzini kwaye yenza isisombululo viscous ecacileyo xa ixutywe namanzi abandayo.Ipolymer ayinayo ityhefu kwaye ikhuselekile ukuba isetyenziswe ekutyeni nakumayeza.I-HPMC ayinavumba, ayinancasa, kwaye inozinzo oluhle kakhulu lwe-thermal.
Phucula ukubambelela
Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kudaka olomileyo kukukwazi ukuphucula ukunamathela.Ukuncamathela kubhekiselele kubuchule bodaka ukunamathela kumphezulu opeyintwayo.I-HPMC iguqula ukuxinezeleka komphezulu wodaka, ngaloo ndlela iphucula ukuncamathela kwayo kwiinxalenye ezahlukeneyo ezifana nekhonkrithi, i-masonry, iinkuni kunye nentsimbi.I-HPMC yenza umaleko okhuselayo ojikeleze amasuntswana e-samente kumdaka, unciphisa ithuba leengqungquthela ezahlula kwi-substrate.
ukugcinwa kwamanzi
I-HPMC yonyusa umthamo wokugcina amanzi wodaka, iphucula ukusebenza kakuhle kwaye ivumela abakhi ukuba bayisebenzise ixesha elide.Ngokuzinzisa isiqulatho samanzi sodaka olomileyo, i-HPMC inokukhuthaza inkqubo yokufakwa kwamanzi esebenzayo ngakumbi, okukhokelela kwimveliso eyomeleleyo, eyomelele ngakumbi.Ugcino lwamanzi oluphuculweyo lukwabonelela ngokungaguquguquki ngcono kwaye konga ixesha kubakhi kunye neekontraka.
Ukuqhubekeka
Ukusebenziseka kubhekiselele kubulula apho umxube wodaka olomileyo unokwakhiwa kwaye ulungiswe ukuhlangabezana neemfuno ezithile.I-HPMC iphucula ukusebenza komxube owomileyo kwaye inika ubumbano kudaka, iququzelela ngcono, ukwakhiwa okuhambelanayo.I-HPMC itshintsha ukunyanzeliswa komphezulu wodaka, inyusa indawo yokunxibelelana phakathi kodaka kunye nomhlaba wokwakha, ngaloo ndlela iphucula ukusebenza.Ukongeza, i-HPMC yenza ifilimu ebhityileyo ejikeleze iqhekeza ngalinye kudaka, ikhusela umxube kwimozulu, inyusa uzinzo kunye nokuqina.
ukwanda kokuqina
Uxinzelelo oluguquliweyo lwaphezulu olwenziwe yi-HPMC kwidaka elomileyo lenza ukuba lizinze ngakumbi kwaye lithintele udaka ukuba luqhekeke kwaye luqhekeke ngokuhamba kwexesha.Isenzo sokubambisana se-HPMC songeza amandla kwimveliso egqityiweyo, iyenza ibe yinto ehlala ixesha elide kwaye ixhathise ukunxiba kunye nokukrazula kwiimeko ezahlukeneyo zokusingqongileyo.Uzinzo olunikezelwa yi-HPMC lukwanciphisa ukungena kwamanzi, ngaloo ndlela kuncitshiswa ukukhula kokungunda kunye nezinye izinto ezingafunekiyo.
Phucula ukumelana nemozulu
I-HPMC inceda udaka olomileyo ukuba lomelele ngakumbi kwiimeko zemozulu ezimandundu, lunyamezele ngokumangalisayo utshintsho lobushushu, imvula kunye nokufuma.Yandisa amandla ebhondi yodaka kwaye icothise ukungena kwamanzi kumxube, onokuwonakalisa kakhulu udaka ukuba ubonakaliswe kumanzi ixesha elide.I-HPMC ikwanceda ukunciphisa izinga le-carbonation yokwaleka, ukukhusela imveliso yokugqibela ukusuka ekuvezweni kwe-carbon dioxide kunye nokuthotywa okubangelwayo.
I-HPMC iye yaba sisithako esiqhelekileyo kwimveliso yodaka olomileyo ngenxa yokukwazi ukuguqula ukuxinana komphezulu, ukuphucula ukugcinwa kwamanzi kunye nokuphucula ukusebenza.Ngokuphucula ukubambelela, abakhi kunye neekontraki banokudala izakhiwo ezinamandla, ezithembekileyo ezingayi kuqhekeza kwaye zinxibe.Izibonelelo zokongeza i-HPMC kwiidaka ezomileyo zibonakaliswe ukwandisa ukuqina, ukusebenza kakuhle, isimo sezulu esihle kunye nozinzo lwemixube eyomileyo, okwenza ukuhlanganiswa kwe-HPMC kwi-mortars ibe yeyona nto ingcono kakhulu yokuphumeza umsebenzi we-masonry osemgangathweni.Ngokusebenzisa imixube yodaka olomileyo olulungisiweyo lwe-HPMC, abakhi banokudala umgangatho ophezulu, onganyangekiyo wamanzi kunye nowomisa ngokukhawuleza izinto ezinciphisa ixesha lokuguqula iprojekthi kwaye zivumela iindawo zokwakha ezikhuselekileyo nokusingqongileyo.
