Isakhiwo samatye esimangalisayo, mhlawumbi indlela yegadi okanye udonga oluhle, olwenziwe ngokucophelela kumatye endalo. Ngokunokwenzeka nge-epoxy resin, la matye adityaniswa kunye. Nangona i-epoxy resin inconywa ngokunamathela kwayo okukhulu, kwenzeka ntoni xa amanzi engena? Ukugcina izakhiwo zamatye ngexesha kuxhomekeke ekuxhathiseni kwamanzi kwiindawo zangaphandle okanye kwiindawo eziphakamileyo ezinomswakama. Eli phepha liphonononga ikhonkco elinomdla kwikhonkco lamatye phakathi kwe-epoxy resin kunye nokumelana namanzi. Makhe siphande phantsi koxinzelelo, ukufuma, kunye novavanyo lwexesha ukuba le bhondi ime njani.
I-Epoxy Resin kunye nendima yayo kwi-Stone Bonding
I-epoxy resin isetyenziswe ngokubanzi ekubopheni amatye ngenxa yeempawu zayo ezinamandla zokubambelela, ezinokumelana nemithwalo enzima kwaye zinikeze ukubamba ixesha elide. Idume kwisakhiwo, imikrolo, kunye nosetyenziso lwangaphakathi, iresin yenza iqhina eliqinileyo lekhemikhali elihlala linamandla kunamatye ngokwawo. Igranite, ilitye lebhastile, kunye nesileyiti ziphakathi kwezinto ezishinyeneyo, ezingenazimbobo ezithi i-Epoxy ilungele ukubotshwa ngenxa yokuqina kwayo, ixesha lokunyanga ngokukhawuleza, kunye nokulungelelaniswa komphezulu. Kodwa ukusebenza kwexesha elide le-epoxy lihlala livavanywa xa lifakwe emanzini-ukusuka kwimvula, ukufuma okuphezulu, okanye ukudibanisa ngokuthe ngqo kwamanzi.
Amanzi anokuchaphazela ama-adhesives amaninzi, ukunciphisa ukudibanisa phakathi kwezinto ngokungena kwizithuba okanye ukusebenzisana neekhemikhali kwi-adhesive. Apha sibuza ukuba i-epoxy resin, kwiindawo eziphakamileyo ezinomswakama, inokugcina ibhondi yayo eqinile phakathi kwamatye xa ijongene namanzi kunye nendlela eyahluke ngayo kwezinye iindlela zokuncamathelisa.
Inzululwazi ngasemva kwe-Epoxy yokumelana naManzi
Epoxy I-resin idla ngokungenwa ngamanzi, kodwa kubalulekile ukwahlula phakathi "kokungangeni kwamanzi" kunye "nokumelana namanzi." I-epoxy ayinakufunxa okanye yophuka ngoko nangoko xa ifumile kuba inokumelana namanzi ukuya kuthi ga kwinqanaba elithile. Kodwa ukubonakaliswa kwamanzi ixesha elide okanye okuqhubekayo-ingakumbi kwiindawo ezinobushushu obuguqukayo-kunokubangela ukuthotywa kancinci. Oku kwenzeka ngenxa yokuba ngamanye amaxesha amanzi angena kwi-micro-cracks kwi-epoxy, mhlawumbi yenza buthathaka ibhondi ekuhambeni kwexesha.
Ukwakhiwa kwe-epoxy enganyangekiyo ngamanzi kuyilwe ngokukodwa kunye nezithako ezongezelelweyo, ezifana ne-agent eqinile kunye nezongezelelo, eziphakamisa ukuqina kwe-epoxy ngokuchasene nokufuma. Oku kuxutywa kuxhaphakile kwisakhiwo sangaphandle okanye kwimo engqongileyo yaselwandle apho utyhileko lwamanzi luqinisekileyo. Sekunjalo, ukuxhathisa amanzi akuthethi ukuba ugqibelele; Ukusetyenziswa kwe-epoxy kwilitye elidibanisayo kuxhomekeke ekwazini ixesha elide kwaye phantsi kweyiphi na imeko enokumelana nokuchayeka kwamanzi.
Ukuvavanya ukuxhathisa kwamanzi kwi-stone bonding
Ukuvavanya ukuxhathisa kwamanzi kwe-epoxy resin ekudibaneni kwamatye, iimvavanyo ezininzi zenziwa kwiisampuli zamatye ezidityanisiweyo ezivezwe kukufuma ngokuhamba kwexesha. Ezinye zezigqibo eziphambili zezi zilandelayo:
1. Ukomelela kweBond yokuqala
Kuvavanyo lokuqala, i-epoxy ibonise ukunamathela okugqwesileyo kwiindidi zamatye ezahlukeneyo, kubandakanya igranite kunye nebhastile, idala ibhondi eyomelele ngokwaneleyo ukuba ibambe phantsi kwemithwalo enzima. Ukuvezwa okufutshane kumanzi akuzange kube nefuthe kolu kuqina kwebhondi yokuqala, oko kuthetha ukuba iibhondi ze-epoxy ziqiniswe ngamatye nakwindawo ezifumileyo.
2.UmBoniso waManzi owandisiweyo
Emva kokuntywila amatye adibeneyo emanzini kwiiyure ze-24, iiyure ze-48, kunye neveki, utshintsho lwaqala ukubonakala kwi-epoxy bond. Nangona ukubonakaliswa okufutshane kwakunempembelelo encinci, emva kweveki amabhondi aqala ukubonisa iimpawu zokuwohloka. Iresin iphuhlise iintanda ezincinci kunye nokutshintsha kwebala okucebisa ukungena kwamanzi. Ilitye lahlala libotshiwe, kodwa ingqibelelo yebhondi iye yehla kwaye yaqala ukubonisa ubuntununtunu boxinzelelo.
3.Ukuguquguquka kobushushu
Ubushushu budlala indima ebalulekileyo kwindlela i-epoxy edibana ngayo namanzi. Amatye aphantsi kwamanzi aphantsi kwamanzi adityaniswe ne-epoxy ayephantsi kokutshintshana kwamaqondo obushushu aphezulu kunye naphantsi. Ukutshintsha kweqondo lobushushu kuvelise ukwandiswa kunye nokucutheka kumatye kunye ne-epoxy, ngoko ke kukhawulezisa ukuqhekeka kancinci. Ezi ntanda zincinci zivumela amanzi ukuba adlule ngokulula kwibhondi, ngoko ke yehlisa ukunamathela ngokubanzi ngokuhamba kwexesha.
4.UMtyhilelo weUV kunye nokufuma
Ukusetyenziswa kwangaphandle kukwabandakanya ukuvezwa kwe-UV. Nangona isibane se-UV singenaso isiphumo esithe ngqo ekuxhathiseni amanzi, sayityheli kancinane i-epoxy, icebisa utshintsho lomphezulu womgangatho. Amandla ebhondi ye-epoxy aye buthathaka ngokukhawuleza ngakumbi kwiindawo zokufuma okuphezulu kuba ukufuma kuvelise amathuba amaninzi okuba amanzi angene kuyo nayiphi na imingxuma okanye iintanda.
Ukuthelekisa kunye nezinye izincamathelisi
Kwizifundo zokumelana namanzi, i-epoxy resin ngamanye amaxesha ihambelana nezinye izinto zokuncamathelisa zamatye ezibandakanya i-polyurethane kunye ne-samente-based adhesives. Nangona i-adhesives esekwe kwisamente inokuxhathisa kakuhle kwamanzi, ngokuhamba kwexesha amanzi ngokuthe ngqo anokubangela ukuba balahlekelwe ngamandla amaninzi. Ngokuchaseneyo, izinto zokuncamathelisa i-polyurethane azinawo amandla okubopha asekuqaleni njenge-epoxy kodwa zinokuguquguquka okubhetele ngaphantsi kobushushu kunye notshintsho lokufuma.
Kwizicelo zokufuma okuphezulu, i-epoxy ngokubanzi igqithise i-sement-based adhesives kodwa ibonise imida ethile xa kuthelekiswa ne-flexible adhesives njenge-polyurethane ngokwemiqathango yokuchasana kwamanzi ixesha elide. I-Epoxy isengcono, nangona kunjalo, kwiisetingi apho ukuguquguquka kungabalulekanga kangako kunokomelela kwebhondi yokuqala kunye nokuqina.
I-Epoxy resin inika amandla okubopha okugqwesileyo kwizicelo zamatye, iyenza ibe lolona khetho lufanelekileyo kusetyenziso oluninzi lwesakhiwo kunye nokuhombisa. Nangona ibonisa ukuxhathisa okulungileyo kwamanzi, ukubonakaliswa kwamanzi rhoqo kunye namandla anamandla-ingakumbi ekutshintsheni amaqondo okushisa-kunokuphazamisa ukuhlala kwayo. Ukwakhiwa kwe-epoxy ukumelana namanzi kunye neendlela zokutywinwa ezongezelelweyo zinceda ukwandisa ixesha lokuphila kweebhondi ezisetyenziswa kwizicelo zangaphandle okanye kwiindawo zokufuma okuphezulu. Nangona i-Epoxy isenokungabi namanzi ngokupheleleyo, inokuba yiglu elungileyo nethembekileyo kwilitye lebhondi kunye nesicelo esichanekileyo kunye neenkxalabo zokusingqongileyo engqondweni.
