I-HPMC kunye ne-HEMC yezinto ezisekelwe kwi-gypsum

Yazisa:

Izinto ezisekelwe kwi-Gypsum zisetyenziswa ngokubanzi kwiiprojekthi zokwakha amandla abo, ukuqina kunye nokumelana nomlilo. Ezi zixhobo zenziwe nge-gypsum, i-compound yeminerali ehlala ifumaneka kumatye e-sedimentary, kunye namanzi. Izinto ezisekelwe kwi-Gypsum ziqhele ukusetyenziswa kwiindonga, iisilingi kunye nemigangatho kwizakhiwo zokuhlala, zorhwebo kunye nezoshishino.

I-Hydroxypropyl methylcellulose (HPMC) kunye ne-hydroxyethyl methylcellulose (HEMC) zii-ethers ze-cellulose ze-nonionic eziqhelekileyo ezisetyenziswa kwiiprojekthi zokwakha. Zisuka kwiipolima zendalo kwaye ziipolima ezinyibilikayo emanzini. Zineepropati ezininzi ezenza ukuba zilungele izinto ezisekelwe kwi-gypsum.

Eli nqaku liza kuphonononga izibonelelo ezininzi zokusebenzisa i-HPMC kunye ne-HEMC kwizinto ezisekelwe kwi-gypsum.

1. Ukuphucula ukusebenza

Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kunye ne-HEMC kwizinto ezisekelwe kwi-gypsum kukukwazi kwabo ukuphucula ubuchule. Xa ezi ethers ze-cellulose zongezwa kumxube, zandisa amandla okubamba amanzi kwi-samente kwaye ziphucula ukuxuba, ukusabalalisa kunye nokuxubha.

Ngenxa yoko, izinto ezisekelwe kwi-gypsum ziye zaba lula ukusebenza kunye nabakhi banokuxutywa ngokulula, basebenzise kwaye balolonge kwiinkcukacha ezifunwayo. Lo mhlaba ubaluleke kakhulu kwiiprojekthi ezifuna uyilo oluntsonkothileyo okanye iipateni ezintsonkothileyo.

Ukongeza, ukwakhiwa okuphuculweyo kuququzelela inkqubo yokwakha ekhawulezayo, ukonga iikontraka kunye nabathengi ixesha kunye nemali.

2. Ukuphucula ukubambelela kunye nokubambelela

Olunye uncedo olubalulekileyo lokusebenzisa i-HPMC kunye ne-HEMC kwizixhobo ezisekwe kwigypsum kukukwazi kwabo ukomeleza iqhina kunye nokuncamathela. Ezi ether ze-cellulose ziphucula uqhagamshelwano phakathi kwekhompawundi kunye ne-substrate, okubangela ukuba kube namandla, ibhondi ehlala ixesha elide.

Lo mhlaba uluncedo kakhulu kwiiprojekthi ezibandakanya iindawo zokufuma eziphezulu, ezifana nezindlu zangasese, amakhitshi okanye amadama okuqubha. Ukudibanisa okuphuculweyo kunye nokubambelela kuthintela izinto ekuqhekekeni, ukuxobula okanye ukuchithwa, naphantsi kweemeko ezinzima.

3. Ukwandisa ukunganyangeki kwamanzi

I-HPMC kunye ne-HEMC ziyaziwa ngokukwazi kwabo ukuphucula ukuxhathisa amanzi. Xa zongezwa kwizinto ezisekelwe kwi-gypsum, ezi ether ze-cellulose zenza uluhlu olukhuselayo olujikeleze amasuntswana, lukhusela amanzi ukuba angangeni phezulu.

Olu phawu lubaluleke kakhulu kwiiprojekthi ezifuna ukuxhathisa kwamanzi aphezulu, njengeendawo ezisezantsi, iziseko okanye iifacade. Ukuchasana kwamanzi okuphuculweyo kunciphisa umngcipheko womonakalo kumswakama, isikhunta okanye isikhunta, ukwandisa ubomi besakhiwo.

4. I-rheology egqwesileyo

I-Rheology yinzululwazi ephonononga ukuguqulwa kunye nokuhamba kwezinto eziphantsi koxinzelelo. I-HPMC kunye ne-HEMC ziyaziwa nge-rheology yazo ebalaseleyo, oku kuthetha ukuba banokutshintsha i-viscosity, i-elasticity kunye neplastiki yezinto ezisekelwe kwi-gypsum.

Olu phawu luluncedo kakhulu kwiiprojekthi ezifuna amanqanaba ahlukeneyo okuhambelana, okufana nemigangatho yokuzimela, ipeyinti yokuhombisa okanye ukubumba. I-rheology egqwesileyo ivumela izinto ukuba zivumelane neentlobo ezahlukeneyo zeemilo, ubungakanani kunye nokuthungwa, okukhokelela kwindawo egudileyo, efanayo.

5. Ukuphucula ukungena emoyeni

I-Aeration yinkqubo yokwazisa amaqamza omoya amancinane kumxube ukuphucula imathiriyeli yokumelana nokunyibilika komkhenkce, ukuqhubekeka kunye nokuqina. I-HPMC kunye ne-HEMC zi-agent ezigqwesileyo zokungenisa umoya, oku kuthetha ukuba zandisa inani kunye nobukhulu bamaqamza omoya kwizinto ezisekelwe kwi-gypsum.

Olu phawu luluncedo kakhulu kwiiprojekthi ezifuna ukumelana nokunyibilika okuphezulu komkhenkce, okunje ngeepavumente zangaphandle, iibhulorho okanye itonela. Ukuphuculwa komoya ophuculweyo kuthintela izinto zokuqhekeka, ukukrazula okanye ukubola ngenxa yokutshintsha kweqondo lokushisa, ukunciphisa iindleko zokugcina kunye nokuphucula ukhuseleko lokwakha.

ukuququmbela:

Ukusetyenziswa kwe-HPMC kunye ne-HEMC kwizinto ezisekelwe kwi-gypsum kuneenzuzo ezininzi kushishino lokwakha. Ezi zi-ether ze-cellulose ze-nonionic ziphucula ukuqhubekeka, ziphucula ukunamathela kunye nokubambelela, ukwandisa ukunyanzeliswa kwamanzi, zibonelela nge-rheology egqwesileyo kunye nokuphucula ukungena komoya.

Ezi mpawu aziphuculi nje kuphela umgangatho wokwakha, kodwa zinciphisa iindleko, zandise imveliso, kwaye zandise ukhuseleko lwabasebenzi bokwakha kunye nabasebenzisi. Ngoko ke, ukusetyenziswa kwe-HPMC kunye ne-HEMC kwizinto ezisekelwe kwi-gypsum ingaba yinto efanelekileyo kunye nengqiqo kuyo nayiphi na iprojekthi yokwakha.
