Ngaphambi kokupenda, udonga lwamadonga okanye ukugcoba kwamhlophe, ngokuqhelekileyo kukho isidingo sokulinganisa izilwanyana okanye izindonga. Apha, abantu banokukhethwa ezimbini: ukusebenzisa ibhodi ye-gypsum okanye ukubuyela kumgangatho wendabuko. Inketho yokuqala iphakanyiswe ngokukhawuleza kwaye inzuzo enzima kumcimbi wokudala izicwangciso, izikhokelo kunye nezilwanyana eziphezulu . Kodwa ngelo xesha, i-drywall inciphisa kakhulu umthamo wegumbi, ukwesaba ukutshutshiswa kwaye inobomi bentsebenzo emfutshane. Yintoni endiyithethayo malunga nokupaka. Le ndlela, nangona kuthatha ixesha elininzi ukufaka, kodwa liya kukhonza ngonaphakade.
Namhlanje iintlobo ezininzi zeeperta zinikwa, kodwa i-plaster engaphezulu kakhulu kwaye isasazeka. Ingumxube wempuphu, into ebophayo leyo isamente. Imixube esekelwe kwi-Cement isetyenziswe kuzo zonke iindawo zokulungiswa, kuba ixabiso layo lixabiso li-2-3 kangaphantsi kwezinto ezifanayo.
Umxube weCement ukuze uphahla
Ngokuxhomekeke kumanqanaba asetyenzisiweyo kwi-plaster kunye namacandelo omxube ahlukaniswe zibe zimbini iintlobo:
- Umxube we-sement-sand for plaster. Isithako esiyinhloko sisanti. Ukulungelelaniswa kweendonga zangaphakathi kunye neengqungquthela, ukuhoxiswa komhlaba ukuya kutsho. Akufanelekanga kwigumbi elinomswakama ophezulu. Ukusetyenziswa kwesamente apha kuncinci, inani le-1: 5 lugcinwa, oko kukuthi, umlinganiselo ofanayo kunye nobutyebi. Ukwahlukana kuphela ukuhambelana kobunjwa kufuneka kube lula.
- I-Cement-lime plaster. Icandelo eliphambili lilime. Ubungakanani bokumiswa ngolu hlobo lulandelayo: i-20 kg yeqhekeza, i-280 kg yesanti, i-50 l yamanzi, i-25 kg ye-samente. Esi sisisombululo sisetyenziselwa emagumbini anomswakama ophezulu (iigaraji, iikhikhini, iifestile, izindlu zokuhlambela), njengoko i-plaster ayilahlekelwa yipropati yayo kwaye ayinyani. I-plaster ipente kunye nokuxutywa kwe-lime ifanelekile ukugqiba iikona, izilonda kunye nezinye izinto apho i-plaster kwisanti ine-adhesion enciphise eludongeni.
Ezi zimbini iintlobo ze-plaster ziqhelekileyo ezisetyenziselwa ukuhlobisa udonga lwangaphambili endlwini. Ezinye izalathisi (i-gypsum, i-acrylic, i-silicone plaster) inomlinganiselo ophezulu kwaye ayinikezeli izixhobo zokubambelela eziyimfuneko. Zikulungele ukulungiswa nokugqiba imisebenzi.
Uluhlu lweendonga kunye nomdongwe womthi: imithetho
Ulwakhiwo olusekelwe kwisamente lunempawu zalo eziyimpawu, kodwa zibonakaliswa kuphela ukuba iimeko zomsebenzi zigcinwe ngokuthe ngqo. Ngoko, umxube wentlabathi kufuneka ube ne-granularity encinci, mhlawumbi indawo iya kuba yintlupheko ebonakalayo, kwaye ukuba amanzi amaninzi afakwa kwisisombululo, umgangatho we-shrinkage kunye neqondo lokunamathela eludongeni liya kuncipha. Iingcali zichonga iinkalo ezininzi ezichaphazela umgangatho wokupaka:
- Kwimimandla engabonakaliyo kunye nomoya omanzi, akukhuthazwa ukuba usebenze nomxube;
- Kule cetywayo kucetyiswa ukuba ungeze igrama ezili-10 ze-shampoo ukuya kwi-10 ilitha yomxube (ukucinywa kuya kususwa);
- Gwema utshintsho ekubunjeni kwamacandelo eludongeni olunye;
- Ukuxolela okwesibini kufuneka kwenziwe kwimiqathango efanayo kunye nokuqala, ngaphandle koko amaqumrhu aya kubonakala kwaye iintambo ziya kubonakala;
- I-samente ekulungele imveliso kufuneka iphile, ukuba yonke umoya ogqithisiweyo;
- ngenxa yomxholo omningi we-samente, uluhlu lwendawo luyakwazi ukuphawula ngenxa yokuguqulwa.
Iingcali zichaza ukuba izikwere ezinkulu zinqweneleka ukusebenzisa amatshini okuhlalisa. Baya kunika i-plaster ye-plaster kuzo zonke iindonga xa kuthelekiswa kunye nokwandisa umkhiqizo wesicelo ngamaxesha ama-5. Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwi-plaster yamasidi yokuhlambela. Khumbula ukuba umsebenzi oqhubekayo wokubeka iileyili ungaqalisa iiveki ezi-3 emva kwesicelo sokugqibela somxube. Kuya kuthatha ixesha elininzi ukuqinisa ngokupheleleyo.
