I-HPMC (Hydroxypropyl methylcelcelcelsulose) yisongezelelo esetyenziswayo kwi-Plaster yoKwakha, ngakumbi ekuphuculeni ukumelana kwamanzi, iipropathi ze-RIOL kunye nokusebenza kokwakha kodaka.
1. Phucula ukugcinwa kwamanzi kodaka
I-HPMC yi-pollymer ye-polymer ye-polymer enokuthi isebenze imeko yenethiwekhi kwisamente okanye kwisamente esekwe gyppum. Olu lwakhiwo lunceda ukugcina amanzi kwaye uthintele i-cemes okanye i-gypsum ekuphulukaneni namanzi ngokukhawuleza ngexesha lenkqubo yokukhula, ngaloo ndlela kuthintela ukuqhekeza okanye ukunciphisa ukunganyangeki kwamanzi. Ngokongeza isixa esifanelekileyo se-HPMC ukuya kwi-Plaster, inkqubo ye-hydration yesamente inokulibaziseka, ukwenza i-Plaster ibe nesakhono esingcono sokugcina amanzi. I-hydrate eyenziwe ngesamente ngexesha lenkqubo ye-hydrate ifuna amanzi awaneleyo ukukhuthaza ukuphendula. Ukulibazisa ukuphulukana kwamanzi kunokuphucula ukuxinana nokuchasana nezinto zokugqibela.
2. Ukuphucula ububi kunye nokuxinana kodaka
Njenge-polymer yongezwa, i-HPMC ayinakuphucula kuphela iimbambano ze-propelocal zodaka, kodwa ziphucule ububi bayo. Xa i-HPMC yongezwa, amandla axhonyiweyo oxhokonxayo aphuculwe, nto leyo encedayo ukuba ibe ngumlinganiso owomeleleyo kwizitena (ezinjengezitena, udonga lwe-gypsim). Kwangelo xesha, i-HPMC yenza ukuba i-PARANT yenze isakhiwo se-denser ngexesha lenkqubo enzima, inciphisa ubukho bezipores zentloko. Iipores ezimbalwa zithetha ukuba kunzima ngakumbi ukuba amanzi angene, ngaloo ndlela aphucule ukumelana kwamanzi kodaka.
I-3. Ukuchasana nokuphucula ubuchule
Isakhiwo se-MOLERAN sinokwenza into efana ne-colloid efana ne-colloid kwi-Plaster, ivumela udaka ukuba lube lolwakhiwo olungeyondawo ngexesha lokunyanga. Njengoko ulwakhiwo luyaphucuka, umhlaba owenziwe phantsi komgangatho ugudileyo kwaye uDeleser, kwaye ukukhohlisa kwamanzi kuncitshisiwe. Ke ngoko, ukuchasana kwamanzi kodaka kuyaphuculwa, ngakumbi iindawo ezinomswakama okanye ezityebileyo, ukongezwa kwe-HPMC kunokuthintela ngokufanelekileyo umswakama ekungeneni kwi-Play.
4. Ukuqina okuphuculweyo kunye nokungasebenzi kwamanzi
Ukuxhathisa kwamanzi kuxhomekeke kubuchule bamanzi omhlaba wezinto, kodwa nabo banxulumene ngokusondeleyo kwisakhiwo sangaphakathi sodaka. Ngokongeza i-HPMC, uzinzo lomzimba kunye neekhemikhali lodaka lungaphuculwa. I-HPMC iphucula i-CORROSION CORTION CORTION YOKUKHUSELEKA I-PARANTSIT kwaye inokuthintela i-quosion yesamente ebangelwa kukungena kwamanzi. Ingakumbi kwintuthuzelo yamanzi exesha elide okanye indawo emsulwa, i-HPMC inceda ukwandisa ubomi benkonzo ye-Plaster kwaye bophucule iipropathi zayo zokwaluphala.
5. Lungisa i-viscofity kunye nokusebenza
I-HPMC ikwanomsebenzi wokuhlengahlengisa i-viscofity kunye nezakhiwo ze-friclocal. Ngokwakhiwa okufanelekileyo, uVeksosity olufanelekileyo unokwenza lula ukuba kusetyenziswe xa kusetyenziswa, kwaye kunokubanjiswa kancinci eludongeni ngaphandle kokwakhiwa ngenxa yokufuma kakhulu ngenxa yokufuma kakhulu ngenxa yokufuma kakhulu ngenxa yokufuma. Ngokulawula ukusebenza kwe-Plaster, abasebenzi bokwakha banokulawula ngcono ukufakwa kwe-Plaster, ngaloo ndlela betshintsha ngokungathanga ngqo kokuphucula ukusebenza kwamanzi kodaka.
I-6. Ukonyusa ukunganyangeki kwe-crack
Ngexesha lenkqubo yokwakha, udaka luthambekele ekufuduseni ngenxa yezinto zangaphandle ezinjengotshintsho lobushushu kunye nokuguquguquka kobushushu, okukhokelela kwimingxunya. Ubukho bamantshontsho abuchaphazeli inkangeleko yodaka, kodwa ikwabonelela ngesitshaneli sokutyikitywa kwamanzi. Ukongezwa kwe-HPMC kunokwandisa ubunzima bodaka, kuyenza ibe nokunganyangeki okuqinileyo ngexesha lenkqubo yokomisa, ngaloo ndlela kuphepha umswakama ukuba ungangeni entlungwini kunye nokunciphisa umngcipheko wokungena kwamanzi.
7. Ukuphucula ukulungelelaniswa nokulula
Ukongezwa kwe-HPMC kunokwenza i-Plaster ikwazi ukulungelelanisa ngakumbi phantsi kweemeko ezahlukeneyo zemozulu. Kwimeko yobushushu obuphezulu, umswakama we-Plaster upapasa ngokukhawuleza kwaye unomdla wokukrazula. Ubukho be-HPMC kunceda ubungozi bugcine amanzi kwindawo eyomileyo, ukuze isantya sayo sokunyanga silawulwa kwaye sibe nomonakalo owenziweyo we-Waterroof obangelwe kukomile ngokukhawuleza. Ukongeza, i-HPMC inokuphucula ukuthambeka kodaka, ukuze ihlale inamathele kakuhle kwimiphezulu eyahlukileyo kwaye akukho lula ukuwa.
I-HPMC idlala indima ebalulekileyo ekuphuculeni ukumelana kwamanzi kodaka, ikakhulu ngale miba ilandelayo:
Ukugcinwa kwamanzi: Ukulibaziseka i-Hydration Hydration, gcina umswakama, kwaye uthintele ukomisa ngokukhawuleza.
Umlinganiso kunye noxinano: BUYUZA ISIQINISEKISO SESIQINISEKISO SESIQINISEKISO SESIQINISEKISO SESIQINISEKISO SE-MALI.
Ukungaxhathisi: Ukunciphisa iipores kunye nokuthintela ukungena kwamanzi.
Ukuqina kunye nokungasebenzi kwamanzi: Ukuphucula uzinzo lwekhemikhali kunye nokungasebenzi komzimba kwezinto kwaye kwandise ubomi benkonzo.
Ukunganyangeki: Khulisa ubunzima bodaka kunye nokunciphisa ukwenziwa kweendawo zokulwa.
Ulwakhiwo ngokulula: Ukuphucula iipropathi ze-shereological yendawo yokuqhekeza kwaye kuphuculwe ukusebenza ngexesha lokwakha. Ke ngoko, i-HPMC ayisiyo yongeniso kuphela yokuphucula ukusebenza kwamanzi, kodwa kukuphucula ukunganyangeki kwamanzi ngokusebenzisa iindlela ezininzi, ukuze i-Plaster igcine izithixo ezichanekileyo kunye nexesha elide kwiindawo ezahlukeneyo ezinobunzima.
