ethula:
Izinto ezisekelwe ku-Gypsum zisetshenziswa kabanzi kumaphrojekthi wokwakha amandla azo, ukuqina nokumelana nomlilo.Lezi zinto zenziwe nge-gypsum, isakhi samaminerali esivame ukutholakala emadwaleni e-sedimentary, namanzi.Izinto ezisekelwe ku-Gypsum zivame ukusetshenziselwa izindonga, uphahla kanye naphansi ezakhiweni zokuhlala, ezohwebo nezimboni.
IHydroxypropyl methylcellulose (HPMC) kanye ne-hydroxyethyl methylcellulose (HEMC) ama-nonionic cellulose ethers avame ukusetshenziswa kumaphrojekthi wokwakha.Asuselwa kuma-polymers emvelo futhi angama-polymers ancibilika emanzini.Zinezakhiwo eziningi ezizenza zilungele izinto ezisekelwe ku-gypsum.
Lesi sihloko sizohlola izinzuzo eziningi zokusebenzisa i-HPMC ne-HEMC ezintweni ezisekelwe ku-gypsum.
1. Thuthukisa ukusebenza
Enye yezinzuzo eziyinhloko zokusebenzisa i-HPMC ne-HEMC ezintweni ezisekelwe ku-gypsum yikhono labo lokuthuthukisa ukusebenza kahle.Uma lawa ma-cellulose ethers engezwa ekuxubeni, akhulisa amandla okugcina amanzi kasimende futhi athuthukise ukuxuba, ukusabalalisa nokudonsa.
Ngenxa yalokho, izinto ezisekelwe ku-gypsum sekulula ukusebenza ngazo futhi abakhi bangakwazi ukuxuba kalula, bazisebenzise futhi bazilolonge ngendlela oyifunayo.Lesi sakhiwo sibaluleke kakhulu kumaphrojekthi adinga imiklamo eyinkimbinkimbi noma amaphethini ayinkimbinkimbi.
Ukwengeza, ukwakhiwa okuthuthukisiwe kusiza inqubo yokwakha esheshayo, konga osonkontileka namakhasimende isikhathi nemali.
2. Thuthukisa ukunamathela nokunamathela
Enye inzuzo ebalulekile yokusebenzisa i-HPMC ne-HEMC ezintweni ezisekelwe ku-gypsum amandla azo okuthuthukisa ukubopha nokunamathela.Lawa ma-ether e-cellulose athuthukisa ukuxhumana phakathi kwenhlanganisela ne-substrate, okuholela kusibopho esiqinile, esihlala isikhathi eside.
Lesi sakhiwo siwusizo ikakhulukazi kumaphrojekthi abandakanya izindawo ezinomswakama ophezulu, njengezindlu zangasese, amakhishi noma amachibi okubhukuda.Ukubopha okuthuthukisiwe nokunamathela kuvimbela impahla ukuthi ingaqhekeki, ixebuke noma icwebezelise, ngisho nangaphansi kwezimo eziyinselele.
3. Khulisa ukumelana namanzi
I-HPMC ne-HEMC nazo zaziwa ngamandla azo okuthuthukisa ukumelana namanzi.Lapho engezwa ezintweni ezisekelwe ku-gypsum, lawa ma-ether e-cellulose enza ungqimba oluvikelayo oluzungeze izinhlayiya, ukuvimbela amanzi ukuthi angangeni phezulu.
Lesi sici sibaluleke kakhulu kumaphrojekthi adinga ukumelana kwamanzi okuphezulu, njengezindlu zangaphansi, izisekelo noma ama-facade.Ukumelana kwamanzi okuthuthukisiwe kunciphisa ingozi yokulimala okuvela kumswakama, isikhunta noma isikhutha, okunweba impilo yesakhiwo.
4. I-rheology enhle kakhulu
I-Rheology yisayensi efunda ukuwohloka nokugeleza kwezinto ezingaphansi kwengcindezi.I-HPMC kanye ne-HEMC baziwa nge-rheology yabo enhle kakhulu, okusho ukuthi bangashintsha i-viscosity, ukuqina nokuqina kwepulasitiki yezinto ezisekelwe ku-gypsum.
Lesi sici siwusizo ikakhulukazi kumaphrojekthi adinga amazinga ahlukahlukene wokuvumelana, njengephansi elizilinganisa, upende wokuhlobisa noma ukubumba.I-rheology enhle kakhulu ivumela izinto ukuthi zivumelane nezimo ezihlukahlukene, ubukhulu kanye nokwakheka, okuholela ekubeni bushelelezi, obufanayo.
5. Ukufakwa komoya okuthuthukisiwe
I-Aeration iyinqubo yokwethula amabhamuza omoya amancane engxubeninge ukuze kuthuthukiswe ukumelana nokuncibilika kwento, ukuqhubezeka nokuqina.I-HPMC kanye ne-HEMC ama-ejenti angcono kakhulu wokungenisa umoya, okusho ukuthi akhulisa inombolo nosayizi wamabhamuza omoya ezintweni ezisekelwe ku-gypsum.
Lesi sici siwusizo ikakhulukazi kumaphrojekthi adinga ukumelana nokuncibilika okuphezulu, njengama-pavements angaphandle, amabhuloho noma amathaneli.Ukufakwa komoya okuthuthukisiwe kuvimbela izinto ukuthi zingaqhekeki, zixebuke noma ziwohloke ngenxa yokushintsha kwezinga lokushisa, ukunciphisa izindleko zokulungisa nokuthuthukisa ukuphepha kwesakhiwo.
Ekuphetheni:
Ukusetshenziswa kwe-HPMC kanye ne-HEMC ezintweni ezisekelwe ku-gypsum kunezinzuzo eziningi embonini yezokwakha.Lawa ma-nonionic cellulose ethers athuthukisa ukucutshungulwa, athuthukise ukunamathela nokunamathela, akhuphule ukumelana namanzi, anikeze i-rheology enhle kakhulu futhi athuthukise ukungena komoya.
Lezi zici azithuthukisi nje kuphela ikhwalithi yokwakha, kodwa futhi zinciphisa izindleko, zandise ukukhiqiza, futhi zithuthukise ukuphepha kwabasebenzi bokwakha kanye nabasebenzisi.Ngakho-ke, ukusetshenziswa kwe-HPMC ne-HEMC ezintweni ezisekelwe ku-gypsum kungaba ukukhetha okuhle nokunengqondo kunoma iyiphi iphrojekthi yokwakha.
