I-putty ne-plaster yizinto ezibalulekile ekwakhiweni, ezisetshenziselwa ukudala izindawo ezibushelelezi nokuqinisekisa ukusimama kwesakhiwo.Ukusebenza kwalezi zinto kuthonywa kakhulu ukwakheka kwazo kanye nezithasiselo ezisetshenzisiwe.I-Methyl Hydroxyethyl Cellulose (MHEC) iyisengezo esibalulekile ekuthuthukiseni ikhwalithi nokusebenza kwe-putty ne-plaster.
Ukuqonda i-Methyl Hydroxyethyl Cellulose (MHEC)
I-MHEC iyi-ether ye-cellulose etholakala ku-cellulose yemvelo, ishintshwe ngezinqubo ze-methylation ne-hydroxyethylation.Lokhu kuguqulwa kunikeza ukuncibilika kwamanzi kanye nezakhiwo ezihlukahlukene zokusebenza ku-cellulose, okwenza i-MHEC ibe isithasiselo esiguquguqukayo ezintweni zokwakha.
Izakhiwo Zekhemikhali:
I-MHEC ibonakala ngokukwazi kwayo ukwenza isisombululo se-viscous lapho incibilika emanzini.
Inamandla amahle kakhulu okwenza ifilimu, ihlinzeka ngesendlalelo esivikelayo esithuthukisa ukuqina kwe-putty ne-plaster.
Izakhiwo Zomzimba:
Kwenyusa ukugcinwa kwamanzi emikhiqizweni kasimende, okubalulekile ekwelapheni okufanele kanye nokuthuthukiswa kwamandla.
I-MHEC inikezela nge-thixotropy, ethuthukisa ukusebenza kanye nokulula ukusetshenziswa kwe-putty ne-plaster.
Iqhaza le-MHEC ku-Putty
I-Putty isetshenziselwa ukugcwalisa ukungapheleli okuncane ezindongeni nophahla, inikeze indawo ebushelelezi yokudweba.Ukufakwa kwe-MHEC ekwenziweni kwe-putty kunikeza izinzuzo ezimbalwa:
Ukusebenza Okuthuthukisiwe:
I-MHEC ithuthukisa ukusabalala kwe-putty, okwenza kube lula ukusebenzisa nokusabalalisa kancane futhi ngokulinganayo.
Izakhiwo zayo ze-thixotropic zivumela i-putty ukuthi ihlale endaweni ngemva kokufaka isicelo ngaphandle kokugoqa.
Ukugcina Amanzi Okuthuthukisiwe:
Ngokugcina amanzi, i-MHEC iqinisekisa ukuthi i-putty ihlala isebenza isikhathi eside, inciphisa ingozi yokomisa ngaphambi kwesikhathi.
Lesi sikhathi esandisiwe sokusebenza sivumela ukulungiswa okungcono nokushelela ngesikhathi sohlelo lokusebenza.
Ukunamathela Okuphezulu:
I-MHEC ithuthukisa izakhiwo zokunamathela ze-putty, iqinisekisa ukuthi inamathela kahle kuma-substrates ahlukahlukene njengokhonkolo, i-gypsum, nesitini.
Ukunamathela okuthuthukisiwe kunciphisa amathuba okuqhekeka nokuhlukaniswa ngokuhamba kwesikhathi.
Ukuqina Okukhulisiwe:
Ikhono lokwenza ifilimu le-MHEC lidala umgoqo ovikelayo othuthukisa ukuqina kwesendlalelo se-putty.
Lo mgoqo uvikela indawo engaphansi kusuka kumswakama kanye nezici zemvelo, ukwandisa impilo yesicelo se-putty.
Iqhaza le-MHEC kuPlaster
I-Plaster isetshenziselwa ukwakha izindawo ezibushelelezi, ezihlala isikhathi eside ezindongeni nophahla, ngokuvamile njengesisekelo sokuqhubeka komsebenzi wokuqeda.Izinzuzo ze-MHEC ekwakhekeni kwe-plaster zibalulekile:
Ukuvumelana Okuthuthukisiwe Nokusebenza:
I-MHEC iguqula i-rheology ye-plaster, ikwenze kube lula ukuxutshwa nokufaka.
Inikeza ukuthungwa okungaguquguquki, okukhilimu okwenza kube lula ukusetshenziswa okubushelelezi ngaphandle kwezigaxa.
Ukugcina Amanzi Okuthuthukisiwe:
Ukwelashwa okufanele kwe-plaster kudinga ukugcinwa komswakama okwanele.I-MHEC iqinisekisa ukuthi ukhonkolo ugcina amanzi isikhathi eside, okuvumela ukugeleza okuphelele kwezinhlayiya zikasimende.
Le nqubo yokwelapha elawulwayo iphumela kungqimba lukakhonkolo oluqinile noluhlala isikhathi eside.
Ukuncishiswa Kwemifantu:
Ngokulawula izinga lokumisa, i-MHEC inciphisa ingozi yokuqhekeka kokuncipha okungenzeka uma ukhonkolo loma ngokushesha kakhulu.
Lokhu kuholela endaweni ekhonkolo ezinzile futhi efanayo.
Ukunamathela Okungcono Nokubumbana:
I-MHEC ithuthukisa izakhiwo zokunamathisela ze-plaster, iqinisekisa ukuthi ibopha kahle ngama-substrates ahlukahlukene.
Ukuhlangana okuthuthukisiwe ngaphakathi kwe-matrix ye-plaster kuholela ekuqedeni okuqinile futhi okuhlala isikhathi eside.
Izindlela Zokuthuthukisa Ukusebenza
Ukuguqulwa kwe-Viscosity:
I-MHEC inyusa i-viscosity yezixazululo ezinamanzi, okubalulekile ekugcineni ukuzinza kanye ne-homogeneity ye-putty ne-plaster.
Umphumela wokuqina we-MHEC uqinisekisa ukuthi izingxube zihlala zizinzile ngesikhathi sokugcinwa nokusetshenziswa, ukuvimbela ukuhlukaniswa kwezingxenye.
Ukulawulwa kwe-Rheology:
Imvelo ye-thixotropic ye-MHEC isho ukuthi i-putty ne-plaster ibonisa ukuziphatha kokunciphisa i-shear, iyancipha ukubonakala ngaphansi kwengcindezi ye-shear (ngesikhathi sokufaka isicelo) kanye nokuthola i-viscosity lapho uphumule.
Lesi sakhiwo sivumela ukusetshenziswa okulula kanye nokuguqulwa kwezinto, kulandelwa ukusetha okusheshayo ngaphandle kokuhlehla.
Ukwakhiwa Kwefilimu:
I-MHEC yenza ifilimu eguquguqukayo futhi eqhubekayo lapho yomiswa, enezela emandleni emishini kanye nokumelana ne-putty esetshenzisiwe kanye ne-plaster.
Le filimu isebenza njengesithiyo ngokumelene nezici zemvelo ezifana nomswakama nokwehluka kwezinga lokushisa, okuthuthukisa impilo ende yokuqeda.
Izinzuzo Zemvelo kanye Nezomnotho
Isengezo Esiqhubekayo:
Kususelwa ku-cellulose yemvelo, i-MHEC iyisengezo esibolayo futhi esinobungani bemvelo.
Ukusetshenziswa kwayo kunomthelela ekusimameni kwezinto zokwakha ngokunciphisa isidingo sezithasiselo zokwenziwa kanye nokuthuthukisa ukusebenza kwezithako zemvelo.
Ukusebenza Kwezindleko:
Ukusebenza kahle kwe-MHEC ekwenzeni ngcono ukusebenza kwe-putty ne-plaster kungaholela ekongeni kwezindleko esikhathini eside.
Ukuqina okuthuthukisiwe kanye nezidingo zokulungisa ezincishisiwe zehlisa izindleko zizonke ezihlobene nokulungisa nokufaka izicelo kabusha.
Ukusebenza kahle kwamandla:
Ukugcinwa kwamanzi okuthuthukisiwe nokusebenza kunciphisa isidingo sokuxutshwa njalo kanye nokulungiswa kwezicelo, ukonga izindleko zamandla nezabasebenzi.
Inqubo yokwelapha eyenziwe kahle eyenziwe yi-MHEC iqinisekisa ukuthi izinto ezisetshenziswayo zithola amandla aphezulu ngokufaka okuncane kwamandla.
I-Methyl Hydroxyethyl Cellulose (MHEC) iyisengezo esibalulekile ekwenzeni ngcono ukusebenza kwe-putty ne-plaster.Ikhono layo lokuthuthukisa ukusebenza, ukugcinwa kwamanzi, ukunamathela, nokuqina kuyenza ibaluleke kakhulu ekwakhiweni kwesimanjemanje.Ngokuthuthukisa ukungaguquguquki, izakhiwo zokufaka isicelo, kanye nekhwalithi iyonke ye-putty ne-plaster, i-MHEC ifaka isandla ezenzweni zokwakha ezisebenza kahle nezisimeme.Izinzuzo zayo zemvelo kanye nokuphumelela kwezindleko kuqhubezela phambili ukuqinisa indima yayo njengengxenye ebalulekile ezintweni zokwakha.Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukusetshenziswa kwe-MHEC ekwakhekeni kwe-putty ne-plaster cishe kuzosakazeka kakhulu, kuqhubekisele phambili intuthuko kubuchwepheshe bokwakha kanye nekhwalithi.
