Imveliso nganye kufuneka ilungiswe ngokweenkcukacha zayo.

Sebenzisa iinjongo zesicelo ezilinganayo

Ukuba uvavanyo kukungena, thelekisa ukungena.

Ukuba uvavanyo luxhasa umnatha, thelekisa ukusebenza komnatha.

Musa ukubeka i-epoxy yokungena ngokuchasene ne-resin yokuzalisa i-seam usebenzisa inqaku elinye legeneric.

Yakha uMyalelo weSilingo phakathi kweSampuli kunye noThengo olugcweleyo

Kwii-odolo zemizi-mveliso enentsingiselo, kuhlala kukho inyathelo eliphakathi eliluncedo phakathi kwesampulu encinci yasimahla kunye nokuthenga isikali sesikhongozeli.

Elo nyathelo ngumyalelo wetyala.

Kutheni umyalelo wetyala ubalulekile

Inceda umthengi avavanye:

• ukupakishwa kwezorhwebo;
• ukuhambelana kwebhetshi;
• ukuphathwa kwendawo yokugcina impahla;
• ijiko lokufunda lomsebenzisi;
• imveliso;
• ukusetyenziswa kwe-resin okwenyani;
• ukuhluka komgangatho kuwo wonke ama-slabs amaninzi; kwaye
• ulungiselelo lomthengisi.

Isampulu yelabhoratri ye-1 kg inobungqina bokuhambelana.

Ayinakungqina ngokupheleleyo ukuthembeka kwemveliso yobuninzi.

Ingcebiso: Yamkele inkqubo, hayi imveliso kuphela

Iiprogram ezingcono ze-epoxy qualification azibuzi kuphela ukuba i-resin idibana nephepha ledatha yobugcisa.

Babuza ukuba ingaba yonke inkqubo yemveliso iyaphinda.

Ukuba i-viscosity ichanekile kodwa abaqhubi abanako ukugqiba i-slab phambi kwe-gelation, inkqubo ayifanelekanga.

Ukuba i-adhesion yomelele kodwa ibhastile elimhlophe liphuhlisa iihalos ezibonakalayo, inkqubo ayifanelekanga kwelo litye.

Ukuba i-resin isebenza ngokugqibeleleyo ehlotyeni kodwa igcine umgca ebusika, inkqubo yonyaka wonke ayifanelekanga.

Ukuba i-epoxy enexabiso eliphantsi ifuna izinto ezininzi ngemitha yesikwere, thelekisa ixabiso eligqityiweyo le-slab kunexabiso lokuthenga.

Ukuba isampulu enye iyasebenza kodwa iibhetshi zorhwebo ziyahluka, phanda ukuguquguquka komthengisi ngaphambi kokwenza umthamo.

Kwaye ukuba i-epoxy idlula iimvavanyo zaselabhoratri kodwa iyasilela ngexesha lokupolisha, themba i-slab egqityiweyo.

Umthengi wakho uthenga ilitye eligqityiweyo-hayi iphepha ledatha ye-epoxy.

Imibuzo Ebuzwa Rhoqo malunga noVavanyo lwe-Epoxy phambi koku-odola ngobuninzi

1. Kufuneka uvavanyo lwefektri yamatye ngaphambi kokuthenga i-epoxy resin ngobuninzi?

Umzi-mveliso wamatye kufuneka uvavanye amaxwebhu, ukuziphatha okuxutywayo, i-viscosity, ixesha lokusebenza, ukunyanga, ukungena, ukunamathela, ukuzinza kombala, ukusebenza kokupholisha, ukusetyenziswa kwe-resin, ukusebenza kobushushu bonyaka kunye nokuhambelana kwebhetshi. Uvavanyo kufuneka lusebenzise elona litye lemveliso kunye nenkqubo nanini na kunokwenzeka.

2. Ngaba i-TDS yomthengisi yanele ukuba ivumele i-epoxy?

Hayi. I-TDS ibalulekile ekuqondeni uqulunqo olucetywayo kunye neemeko zovavanyo, kodwa ayikwazi ukuqikelela ngokupheleleyo ukusebenza kwebhastile ngalinye, igraniti, i-onyx, okanye ilitye lobunjineli. Sebenzisa idatha yobugcisa ukwenza uluhlu olufutshane lwemveliso, emva koko uqinisekise ukusebenza ngovavanyo lwefektri olulawulwayo.

3. Mangaphi amacwecwe amatye ekufuneka avavanywe phambi komyalelo wesambuku?

Akukho nombolo jikelele. I-slab enye idla ngokungonelanga kuba ilitye lendalo liyahluka. Vavanya ii-slabs zabameli ezininzi ezigubungela umahluko oqhelekileyo kwi-porosity, iintanda, umbala kunye nolwakhiwo. Okukhona ziphezulu iindleko zokungaphumeleli okanye ukuba mkhulu ulandelelwano olucwangcisiweyo, kokukhona uqilima ngakumbi inkqubo yesiqinisekiso.

4. Luluphi olona vavanyo lubalulekileyo lwe-epoxy ekusetyenzweni kwamatye?

Akukho vavanyo lubaluleke kakhulu kwisicelo ngasinye. Ukulungiswa kokuqhekeka kwegranite, ukungena kunokubaluleka. Kwimarble emhlophe, ukuzinza kombala kunye nokungena okulawulwayo kunokulawula. Ukuxhasa i-mesh, ukumanzisa kunye nokuphatha izinto zokunyanga. Ukufakwa kwe-vacuum, ukuzinza kwe-viscosity kunye nexesha lokusebenza kubalulekile. Vavanya ngokowona mngcipheko wemveliso.

5. Ngaba umzi-mveliso kufuneka ufake iodolo yovavanyo ngaphambi kokuthenga isambuku esipheleleyo se-epoxy?

Kwimiqulu yemizi-mveliso enentsingiselo, iodolo yolingo ihlala ilinyathelo eliphakathi elikrelekrele. Ivumela umzi-mveliso ukuba uvavanye iibhetshi zorhwebo, ukupakishwa, ukungaguquguquki kwabaqhubi, ukusetyenziswa kokwenyani, ukuveliswa kwemveliso, ukuziphatha kwamaxesha onyaka, kunye nokuthembeka komthengisi ngaphambi kokuba uzibophelele ekuthengeni okukhulu.
