I-Putty uhlobo lwezinto zokuhlobisa isakhiwo. Ingqimba ye-putty emhlophe ebusweni begumbi elingenalutho esanda kuthengwa ivame ukuba ngaphezu kwama-90 ngombala omhlophe kanye nokucwebezela okungaphezu kwama-330. I-Putty ihlukaniswe ngodonga lwangaphakathi nodonga lwangaphandle. I-putty yangaphandle kufanele imelane nomoya nelanga, ngakho-ke ine-glue ephezulu, amandla aphezulu kanye nenkomba yokuvikela imvelo ephansi kancane. Inkomba ephelele ye-putty yangaphakathi yodonga ilungile, inempilo futhi ivikela imvelo, ngakho-ke udonga lwangaphakathi alusetshenziswa ngaphandle kanti udonga lwangaphandle alusetshenziswa ngaphakathi. Ngokuvamile i-putty isekelwe ku-gypsum noma kusimende, ngakho-ke ubuso buyaguga futhi kulula ukubopha ngokuqinile. Kodwa-ke, ngesikhathi sokwakha, kusadingeka ukusebenzisa ungqimba lwe-interface agent enkambeni yesisekelo ukuvala inkambo yesisekelo, nokuthuthukisa ukunamathela kodonga, ukuze i-putty ikwazi ukubopha kangcono ebusweni besisekelo.
Inani le-HPMC elisetshenziswa ngempela lincike endaweni yesimo sezulu, umehluko wokushisa, ikhwalithi yempuphu yomlotha we-calcium yendawo, iresiphi eyimfihlo yempuphu ye-putty kanye "nekhwalithi edingekayo ngumsebenzisi". Ngokuvamile, phakathi kuka-4kg no-5kg.
I-HPMC inomsebenzi wokugcoba, ongenza i-putty powder isebenze kahle. I-Hydroxypropyl methylcellulose ayihlanganyeli kunoma yikuphi ukusabela okuhlanganisiwe, kodwa inomphumela wokusiza kuphela. I-putty powder uhlobo lokusabela okuhlanganisiwe ebusweni bamanzi nasodongeni,
Izinkinga ezithile:
1. Ukususwa kwempuphu ye-putty
A: Lokhu kuhlobene nomthamo we-calcium yelayisi, futhi kuhlobene nomthamo kanye nekhwalithi ye-cellulose, okubonakala ngesilinganiso sokugcina amanzi somkhiqizo. Izinga lokugcina amanzi liphansi futhi isikhathi sokumanzisa i-calcium yelayisi asanele.
2. Ukuhlubula nokugoqa i-putty powder
A: Lokhu kuhlobene nezinga lokugcina amanzi. I-viscosity ye-cellulose iphansi, okulula ukuyenza noma umthamo wayo mncane.
3. Iphuzu lenaliti lempuphu ye-putty
Lokhu kuhlobene ne-cellulose, enesici esibi sokwenza ifilimu. Ngesikhathi esifanayo, ukungcola ku-cellulose kunokusabela okuncane ne-calcium yomlotha. Uma ukusabela kukhulu, i-putty powder izobonisa isimo sezinsalela ze-tofu. Ayikwazi ukuya odongeni futhi ayinawo amandla okubopha. Ngaphezu kwalokho, iyenzeka nasemikhiqizweni efana namaqembu e-carboxy axutshwe ku-cellulose.
