Gaze zingangenwa of eziphathekayo. Additive injalo ukuba zingangenwa

Zingangenwa eziphathekayo kuyimfuneko ukwenzela ukukhusela izinto kwimiphumo eyonakalisayo amanzi. Kutshanje, i ixhaphake kakhulu phakathi kwazo zonke ezinye iintlobo zingangenwa bokufumana inyathelo.

Imfuneko ukusebenza zingangenwa

Eziphathekayo kubonakala monolithic kuphela, kodwa enyanisweni ngayo pores, apho amanzi, utshabalalisa izinto wezifundo. Ngena ukuba ngesamente engorged ngamanzi, nguye delamination le udaka kunye nezinye Ipeyinti zokuhombisa, kukuvela nokuvunda kwaye nesihumba, ngokunjalo ukuqhekeka. Ukuze siphephe izenzakalo ezinjalo, ehlolayo amanzi.

Kwizazi gaze zingangenwa

Gaze zingangenwa ikhonkrithi ineendlela ezininzi phezu kwezinye iintlobo zezixhobo ukuze sikhuseleke. Xa kuthelekiswa ne umbandela nqanawa, ukuba elide kakhulu, ukongeza, zinokungena kwamalungu emanzini. Kwaye ukuba wenze umsebenzi, engayigcini ubugcisa, umqulu liya kuhlala phantsi umoya, apho kungekudala kuya kubangela exobukayo nokufuma. Xa siqwalasela itha zokwakha, ayinakuba yi ductility ezaneleyo, nto leyo iba unobangela neentanda ezenzeka ngexesha shrinkage lwesiseko. Imastic, umzekelo, ubuncinane yaye iimpawu eziyimfuneko luthambe, kodwa oko kuxhomekeke ekubeni ntshikilelo ngoomatshini.

Faka gaze zingangenwa

Gaze izinto amanzi iyodwa kumgaqo ukusebenza kwawo. Ukuba ukuvumelana elulwelo, lihlaba kungena pores uzalise neentanda ezincinane.

Material yaqaphela luhlobo eyomileyo, kufuneka bungxengwe ngamanzi, yaye emva koko isicelo eludongeni, esebenzisa ibhrashi (akwazi endaweni irola). Noko ke, ukuba ufuna ukugqiba umsebenzi ngokukhawuleza kangangoko kunokwenzeka, kucetyiswa ukuba usebenzise kwibhotile yokufefeza.

Emva kokuba nokusebenzisa amanzi ulwelo zidibana kunye ikhonkrithi, ngokwandisa ubomi ngesakhiwo yobomi. Le nto ubunjwe ngokupheleleyo na izithako zemvelo, ngoko akukho ingozi empilweni. Sebenza kunye kwengoma kunokuba zombini ngaphakathi nangaphandle kwezakhiwo. Sebenzisa kube lula kakhulu. Xa kwenzeka polymerization, lo eziphathekayo ifikelele efanayo umboniso, nto leyo woyike nefuthe ngoomatshini. iimpawu adhesion Excellent musa ukuvumela izinto ukushenxa ukusuka kwisiseko.

Phakathi iimpawu ezintle kunokuba ubuchule ihloniphekile:

• ukukhusela eziphathekayo nxamnye ukungena kokufuma;
• sandise ubomi ngesakhiwo lobomi;
• usandula eyakhelwe ukomeleza kwisiseko;
• ukukhusela izixhobo.

Field yokusebenzisa wajula zingangenwa

Eziphathekayo ngamanzi, ezendeleyo wafumana ukusasazwa kwayo ngokubanzi. Ukongeza ukukhusela iziseko zangaphandle izakhiwo, kunokwenzeka ukuba ukusebenza iindawo yangaphakathi yeendonga angaphantsi, athwale amanzi amadama, waphatha izinto iindawo zangasese kunye Kitchen.

ukulungiselela eziphathekayo phambi kokuba nokusebenzisa amanzi

Umphezulu kufuneka zilungiswe ngokucophelela, kuba oko kuyimfuneko ukukhulula oko ukusuka amabala ipeyinti endala, ubumdaka, grease. Ngokuyimfuneko kucetyiswa ukuba akhulule zeendawana evela izilonda fungal, kunye ukungunda, ukuba ezinjalo. Xa khona phezu lathamba linyanzelisa udaka ukuba siyitshabalalise; ve unyango uzinzo of deep umthondo primer kuqamba.

zingangenwa Ulwelo of ikhonkrithi kufuneka abekwe endaweni ethe tyaba. Ngoko ke, ukuba kukho iintanda ngokwesiseko, kufuneka balahle kubo, ekuqaleni ukuba ukusombulula intsinda-badala ithwalwa kwaye ziphathwe sisincoko okhethekileyo, ezendeleyo. Field edlula kuyilo kweenkqubo zonxibelelwano kufuneka utywinwe kakuhle.

Iimpawu ze isicelo

Ukuba umsebenzi ukuba isiseko esitsha eziphathekayo, ubume ukutyabeka kufuneka aveze umaleko ogama ubukhulu 1 mm. Ungenza inkqubo yonxibelelwano ukuba uphume ongaphantsi kunye phantsi. Sebenzisa ibhrashi kuyacetyiswa kwimeko ethile engamanzi. On sale kukho amanzi of ngekhonkrithi, ekuthi kujongwe ukuba isetyenziswe kunye spatula, kufanelekile, xa iziseko endala adinga ukhuseleko. Kuyimfuneko ukuba isicelo umaleko, ogama ubukhulu ngu-2 mm.

Apho umxube gaze yasetyenziswa ukukhusela amalungu, kwakunye conjugations izinto eziphathekayo. Ngenxa yoko izinto akayeki. Ngaphambi kokuba liqhube ezivuzayo kucetyiswa uyiluke 2.5 cm ngokunzulu.

Ukuba zingangenwa gaze eziphathekayo angamelwa umxube yokulungisa onako kupheliswe iimpazamo neentanda amakhulu isiseko sendlu. Sebenzisa i imveliso kufuneka ngokubambisana kunye nokuqinisa umnatha. Ebubanzini Umaleko kufuneka alingane malunga-10 mm, ngoko akwazi ukufezekisa iziphumo ezidibanisayo kuphela.

Additive ukuba zingangenwa

Ukuze adlulisele amanzi umgangatho eziphathekayo, ngamanye amaxesha basebenzisa kudla ezizodwa. Baya kuvela kuqamba elomileyo. ukusetyenziswa mxube amancinci kakhulu kwaye ilingana no-1% ngokobunzima zesamente, nesetyenziswa xa kuxutywa isisombululo. Ukuba awuyazi umthamo zesamente, sebenzisa kg 4 1 m ³ eziphathekayo.

Additive ukuba zingangenwa eziphathekayo lisetyenziswa kunye nesisombululo apho ezimbaxa agalelwe emva kokuba amanzi. Ekuqaleni, kuyimfuneko ukudibanisa isongezo ngamanzi, ezilandelayo lomenzi. Ngokuqhelekileyo, 1 kg ubume kufuneka isetyenziswe iilitha 0.75. Echukumisayo kufuneka kwenziwe kwisithuba kwemizuzu emibini usebenzisa isixhobo sokugrumba, imiselwe ku isantya eliphantsi. Musa ukwenza imixube ezininzi kangaka, akusayi kuba nako ukuphuhlisa ukuba imizuzu emi-5. Isisombululo uzilungiselele kufuneka engekabili mixer, ngaphandle khefu kokugxojwagxojwa omnye imizuzu eli-10. Kuphela ngoko ungenza yokugcwalisa isisombululo olunyityilikisiweyo.

ezinjalo e amanzi eziphathekayo, ngaba ngokuqhelekileyo ingasetyenziswa kunye namanye amacandelo ezifana plasticizer okanye nokubanda. Ungakhetha ukwakhiwa ke amanzi eziphathekayo, apho ukhetha ukusebenza. Ingakumbi abo ezinkulu ziye ichazwe ngasentla. Kodwa umphezulu ngamanzi eziphathekayo, umzekelo, akanayo imali elifanayo imivuzo gaze, ngoko ke kucetyiswa ukuba usebenzise abokugqibela babo.
