Iimpawu zezi zinto, ezifana nokuqhubekeka kunye nokubambelela, zibalulekile kwisicelo sabo esiyimpumelelo. I-Methylhydroxyethylcellulose (MHEC) iye yatsala ingqalelo ngenxa yamandla ayo okuphucula ukusebenza kwezinto zokwakha.
1.2 Iinjongo:
Injongo ephambili yayikukufunda umphumo we-MHEC kwiipropati ze-putty kunye ne-gypsum powder. Iinjongo ezithile zibandakanya ukuvavanya ukuqhubela phambili, amandla ebhondi, kunye nokubeka ixesha lokuphucula ukuqulunqwa kwezi zinto.
Ukujongisisa uluncwadi:
2.1 I-MHEC kwizinto zokwakha:
Uphononongo lwangaphambili lubonise ukuguquguquka kwe-MHECs ekuphuculeni ukusebenza kwezinto ezahlukeneyo zokwakha, kubandakanywa udaka olusekelwe kwi-samente kunye neemveliso ezisekelwe kwi-gypsum. Uphononongo loncwadi luphonononga iindlela apho i-MHEC ichaphazela ukusebenza, ukugcinwa kwamanzi, kunye nokubambelela.
2.2 Iiresiphi zeputty kunye nodaka:
Ukuqonda izithako kunye neemfuno ze-putty kunye ne-gypsum powder kubalulekile ekuqulunqeni umxube osebenzayo. Eli candelo liphonononga ukuqulunqwa kwemveli kwaye lichonge iinkalo zokuphucula ukusebenza kunye nokuzinza.
indlela:
3.1 Ukukhethwa kwezinto:
Ukukhethwa ngokucokisekileyo kwezinto ezibonakalayo, kubandakanywa i-putty kunye ne-gypsum powder kunye ne-MHEC, ibalulekile ekufezekiseni iziphumo ezifunwayo. Uphononongo luchaza iinkcukacha zezinto ezisetyenzisiweyo kunye nengqiqo emva kokukhethwa kwazo.
3.2 Uyilo lovavanyo:
Inkqubo yovavanyo ecwangcisiweyo yaphuhliswa ukuhlalutya umphumo wokugxininiswa kwe-MHEC eyahlukeneyo kwiipropati ze-putty kunye ne-stucco. Iiparamitha eziphambili ezifana nokusebenza, amandla ebhondi kunye nexesha lokuseta zilinganiswa kusetyenziswa iindlela zovavanyo ezisemgangathweni.
Iziphumo neengxoxo:
4.1 Ukwakhiwa:
Impembelelo ye-MHEC ekusebenzeni kwe-putty kunye ne-stucco ivandlakanywa ngeemvavanyo ezifana novavanyo lokuhamba kwebhentshi kunye novavanyo lwe-slump. Iziphumo zahlaziywa ukugqiba ugxininiso olufanelekileyo lwe-MHEC olulinganisa ukuphuculwa kwenkqubo ngaphandle kokuphazamisa ezinye iipropati.
4.2 Amandla okuncamathela:
Amandla ebhondi ye-putty kunye ne-stucco ibaluleke kakhulu kwindlela abadibanisa ngayo kwii-substrates ezahlukeneyo. Iimvavanyo zokukhupha kunye nemilinganiselo yamandla ebhondi zenziwa ukuvavanya umphumo we-MHEC ekunamatheleni.
4.3 Seta ixesha:
Ukumisela ixesha yiparameter ebalulekileyo echaphazela isicelo kunye nokomisa kwe-putty kunye ne-stucco. Olu pho nonongo luphande indlela ugxininiso olwahlukileyo lwe-MHEC oluchaphazela ngayo ixesha lokumisela kunye nokuba kukho uluhlu olufanelekileyo olufanelekileyo kwizicelo eziphathekayo.
ukuququmbela:
Olu pho nonongo lubonelela ngolwazi oluxabisekileyo malunga nokulungiswa kwe-putty kunye ne-gypsum powders usebenzisa i-MHEC. Ngokuhlalutya okucwangcisiweyo kweempembelelo ze-MHEC ekusebenzeni, amandla ebhondi kunye nexesha lokumisa, uphando luchonge ukuqulunqwa okufanelekileyo kokuphucula ukusebenza ngokubanzi. Ezi ziphumo zinokunceda ukuphuhlisa imathiriyeli yokwakha ephuculweyo kunye nokusebenza okuphuculweyo kunye nokuzinza.
Umkhombandlela wexesha elizayo:
Uphando lwexesha elizayo lunokuhlola ukuqina kwexesha elide kunye nemozulu ye-MHEC-modified putty and stuccoes. Ukongeza, amaphononongo okuba nokwenzeka kwezoqoqosho kunye nokwandiswa kwemixube ephuculweyo inokuxhasa ngakumbi ukusetyenziswa okubonakalayo kwezi mathiriyeli kushishino lokwakha.
