Lyu Bukanqinishe: Iimpawu kunye nokubalulwa

Lyu sikwi into kokuba eninzi kokufaneleka. Chief phakathi kuzo yokusebenza kwalo. Ingasetyenziswa ngenxa kuncanyatheliswe amatye, imiphezulu ngeglasi, ngesinyithi, iinkuni, yodongwe, lyu kunye istro, kwakunye nezinye izinto. Oku kungenxa adhesion ophezulu ubume kuzo zonke ezi ntlobo zezixhobo. Njengokuba Umatshini ngoko bakhonza lyu, ukuba kucacile kwisihloko.

Compound nomphezulu yayo uncedo iqinisekisa ukuxhathisa amachiza, bazifake ubushushu, izinto ezahlukeneyo ebelihlasela lokusingqongileyo, amaqondo obushushu aphezulu kunye nokufuma. Loo ayimbumba kusetyenziswe olubanzi kuluhlu lobushushu ukusuka -60 ukuya +120 degrees Celsius. Ukongeza, lyu ngcina inika uqhagamshelwano nkqi, uzinzile lokuba iziganeko ezifana ngumngundo kunye fungi izifo. impahla podvspenivaniya ikuvumela ukuba uqinisekise ukuba isithuba phakathi iindawo nisondelelane ziye zizaliswe ngokupheleleyo kubo. Ukungabikho kwi izinyibilikisi kunye amavumba iqinisekise ngokhuseleko ubuninzi ngexesha lokusebenza.

Kukho candelo-amabini icandelo elinye-lyu ngcina. Le ndlela yesibini kulula ukuyisebenzisa kunye ezimqoka enkulu. Kubume bayo kukho prepolymers isocyanate. Ngenxa viscosity eliphezulu imveliso inika isicwangciso elihle lokuqala. baphendule isocyanate ngamanzi esesibhakabhakeni kukhokelela yokusabela ngemichiza. ngenxa yaso ukuyilwa iibhondi cross-eziphilayo, kangangokuba uqhagamshelwano uba namandla kakhulu.

-Component ezimbini lyu ngcina iqulethe kubume bayo isibini yeekhomponenti leyo xa kusetyenziswa kuphela babe viscosity eliphantsi. Kuphela emva kokuba elisetyenziswa mechanical eyenziwa olune isocyanate kunye arhente polyol ephilisa, nto leyo ebangela zikwimeko esebenza ngayo le ngcina. Xuba izakhi eziyimfuneko kunye nokugcina ngenyameko iimeko inkqubo ethile, ngamanye olinganise ezinqwenelekayo, ubude ixesha neqondo lobushushu. Xa indlela echanekileyo inkqubo intsebenziswano kwamalungu. Ukuthobela yonke imiqathango kukhokelela ekubeni iimpawu amandla yokuqhagamshelwa esebenzisa lyu iglu abe phezulu kakhulu.

Iglu ngokusekelwe lyu inokuba luncedo kakhulu ekubekeni parquet floor. Kuba iimeko Russian kucetyiswa ukuba kusetyenziswe imixube yecandelo-ezimbini musa ziqulathe izinyibilikisi okanye emanzini. Ezo zililo ziyakwazi ukumelana cishe umthwalo yokusebenza, ngoko ke kufuneka isetyenziselwe ngokubekwa kwibhodi okanye uluhlu. Le ngcina lyu linokusetyenziswa phantse kuzo zonke iintlobo iziseko ngaphandle kokufuna priming lokuqala. Iintsalela kwenkqubo ukususa ngokwaneleyo nje. Lyu ngcina kuqinisekisa amandla eliphezulu shear.
