ukwazisa
Udaka lomxube owomileyo ngumxube wesamente, isanti kunye nezongezo zekhemikhali. Isetyenziswa ngokubanzi kulwakhiwo ngenxa yokugqwesa kwayo okugqwesileyo kunye nokuqina. Enye yezinto ezisisiseko zodaka lomxube owomileyo yi-hydroxypropyl methylcellulose (HPMC), esebenza njenge-binder kwaye ibonelela ngokufana okufunekayo. Kweli nqaku sixoxa ngeenzuzo zokusebenzisa ukugcinwa kwamanzi aphezulu HPMC kumxube owomileyo udaka.
Kutheni udaka oluxutyiweyo olomileyo lufuna i-HPMC?
Imixube eyomileyo iyimixube entsonkothileyo yamacandelo ahlukeneyo afuna ukuxubana ngokucokisekileyo ukufezekisa ukuhambelana okufunwayo. I-HPMC isetyenziswa njenge-binder kwi-dry-mix mortars ukuqinisekisa ukuba onke amacandelo adibanisa kunye. I-HPMC ngumgubo omhlophe onyibilika ngokulula emanzini kwaye uneempawu ezintle zokuncamathelisa. Ukongeza, inceda ukugcina ukufuma kwi-dry-mix mortar.
Izibonelelo zokusebenzisa iHPMC yoGcino lwaManzi aphezulu kwiDry-Mix Mortar
1. Umgangatho ozinzileyo
Ukugcinwa kwamanzi aphezulu i-HPMC inceda ukugcina ukuhambelana kodaka lomxube owomileyo. Inceda udaka lokuphatha kakuhle kwaye lubonelela ngomphezulu ogudileyo. Ukusetyenziswa kwekhwalithi ephezulu ye-HPMC iqinisekisa umxube owomileyo womxube womgangatho ohambelanayo kungakhathaliseki ubungakanani bebhetshi kunye neemeko zokugcina.
2. Ukusebenza ngcono
Ukugcinwa kwamanzi aphezulu i-HPMC yinxalenye ebalulekileyo yodaka oluxubeneyo olomileyo, olunokubonelela ngokusebenza okungcono. Isebenza njenge-lubricant kwaye inciphisa ukungqubana phakathi kodaka kunye ne-substrate. Kwakhona kunciphisa ukubunjwa kwamaqhuma kunye nokuphucula ukuxutywa kodaka oluxubeneyo olumileyo. Isiphumo singumxube ogudileyo, osebenza ngakumbi.
3. Ukuphucula ukubambelela
Ukugcinwa kwamanzi okuphezulu kwe-HPMC kunokwandisa ukusebenza kwebhondi yodaka oluxubeneyo elomileyo. Inceda ibhondi yodaka eyomileyo eyomileyo ingcono kwi-substrate, ibonelela ngokugqibezela ixesha elide. I-HPMC inokunceda ukunciphisa ixesha lokumisa umxube owomileyo, oku kuthetha ukuba ixesha elincinci elifunekayo ukuze udaka lubekwe, okukhokelela ekunciphiseni okuncinci kunye nokuqhekeka.
4. Yongeza ukuguquguquka
Ukugcinwa kwamanzi aphezulu HPMC ibonelela bhetyebhetye olongezelelweyo udaka umxube owomileyo. Iphucula iimpawu ze-elastic zodaka ukwenzela ukuba ikwazi ukumelana nokwandiswa kwe-thermal kunye nokunciphisa. Oku kuguquguquka kwanda kunciphisa umngcipheko wokuqhekeka ngenxa yoxinzelelo phantsi kweemeko eziqhelekileyo zokusingqongileyo.
5. Ukugcinwa kwamanzi
Ukugcinwa kwamanzi okugcinwa kwamanzi aphezulu i-HPMC ibaluleke kakhulu kudaka oluxubeneyo elomileyo. Inceda ukugcina ukufuma kodaka, okwenza kube lula ukusebenza ngexesha lokwakha. Iimpawu zokugcina amanzi ze-HPMC ziqinisekisa kwakhona ukuba udaka aluwomi ngokukhawuleza, luvumela ukuba luhlale bhetele, luphucule ukugqitywa okupheleleyo.
ukuququmbela
Ukugcinwa kwamanzi aphezulu i-HPMC yinxalenye ebalulekileyo yodaka oluxutyiweyo olomileyo. Iphucula ukusebenza, ukuhambelana kunye neempawu zokubambelela kodaka. Kwakhona kwandisa ukuguquguquka kunye nokugcinwa kwamanzi kwiipropati zodaka. Ngokubanzi, ukusetyenziswa kwekhwalithi ephezulu ye-HPMC kwi-dry-mix-mix mortars iqinisekisa ukuba imveliso egqityiweyo ihlangabezana nemigangatho efunekayo, inika amandla ayimfuneko kunye nokuqina.
