Indima yezixhobo zokunyanga umphunga wekhonkrithi
Ngexesha lokwakhiwa kwebusika, iqondo lokushisa liphantsi kwaye umoya womile. Ikhonkrithi iqina kancinci kwaye amandla kunzima ukuhlangabezana neemfuno ezilindelekileyo. Ukuqina kweemveliso zekhonkrithi ngaphandle kokunyangwa komphunga akufanele kuhambelane nomgangatho. Ukusetyenziswa kokunyanga umphunga ukuphucula amandla ekhonkrithi kunokufezekiswa kula manqaku mabini alandelayo:
1. Thintela iintanda. Xa ubushushu bangaphandle buhla ukuya kwindawo yokukhenkceza, amanzi akwikhonkrithi aya kuba ngumkhenkce. Emva kokuba amanzi ajike abe yiqhwa, umthamo uya kwanda ngokukhawuleza ngexesha elifutshane, eliya kutshabalalisa isakhiwo sekhonkrithi. Kwangaxeshanye, imozulu yomile. Emva kokuba ikhonkrithi iqina, iya kwenza iiNgcali kwaye amandla abo aya kuba buthathaka ngokwendalo.
2. Ukunyanga komphunga ngekhonkrithi kunamanzi awoneleyo okuhambisa amanzi. Ukuba ukufuma okuphezu komhlaba kunye nangaphakathi kwikhonkrithi yoma ngokukhawuleza, kuya kuba nzima ukuqhubeka nokuhanjiswa kwamanzi. Ukunyanga umphunga akunakuqinisekisa kuphela iimeko zobushushu ezifunekayo ukuze kuqiniswe ikhonkrithi, kodwa kukwafumisa, kucothise ukuphuphuma kwamanzi, kwaye kukhuthaze ukusabela kwe-hydration yekhonkrithi.
Indlela yokwenza ukunyangwa komphunga ngomphunga?
Ekunyangelweni kwekhonkrithi, qinisa ukulawulwa komswakama kunye nobushushu bekhonkrithi, ukunciphisa ixesha lokuvezwa kwekhonkrithi yomhlaba, kwaye ugubungele ubuso obucacileyo bekhonkrithi ngokuqinileyo ngexesha elifanelekileyo. Inokuthi igqunywe ngelaphu, iphepha leplastiki, njl njl. Ngaphambi kokuba uqale ukunyanga ikhonkrithi eveza umaleko okhuselayo, isigqubuthelo kufuneka sisongwe kwaye umphezulu kufuneka ukhuhlwe kwaye ucinezelwe nge-plaster ubuncinane kabini ukuze ugudise kwaye ugqunywe kwakhona.
Ngeli xesha, kufuneka kuthathelwe ingqalelo ukuba ukugqithiswa akufanele kudibanise ngqo nomgangatho wekhonkrithi de ikhonkrithi iphiliswe ekugqibeleni. Emva kokuthulula ikhonkrithi, ukuba imozulu ishushu, umoya womile, kwaye ikhonkrithi ayinyangeki ngexesha, amanzi akwikhonkrithi aya kuba ngumphunga ngokukhawuleza, kubangele ukuphelelwa ngamanzi emzimbeni, ukwenzela ukuba amasuntswana esamente abumba ijeli akakwazi ukuqinisa ngokupheleleyo. amanzi kwaye ayinakunyangwa.
Ukongeza, xa amandla ekhonkrithi engonelanga, ukuphuphuma komphunga kwangaphambi kwexesha kuya kuvelisa i-shrinkage deformation enkulu kunye nokuqhekeka kokuqhekeka. Ngoko ke, kubaluleke kakhulu ukusebenzisa ikhonkrithi yokunyanga ijeneretha yomphunga ukunyanga ikhonkrithi kwiinqanaba zokuqala zokuthulula. Ikhonkrithi kufuneka inyangwe ngokukhawuleza emva kokubunjwa kokugqibela kwaye ikhonkrithi eyomileyo kufuneka inyangwe ngokukhawuleza emva kokugalelwa.
