Two-ingxenye ingcina (epoxy, polyurethane)

ingcina Amabili ingxenye - iqembu eliphezulu anamathelayo, okuhlanganisa labo kumakhemikhali awuketshezi kungukuthi enikeziwe. Izingxenye ezisemqoka - inhlaka (binders) kanye hardeners (egcinwe eceleni, kungaba ekumisweni noma powder).

I chemical yokusabela ukuthi iqala emva ukuxuba lezi zingxenye ezimbili, ukuphilisa Ukwakheka, ezuza kwamaminithi ambalwa amandla adhesion kokuqala. Ijubane sokwelapha incike lokushisa kanye nekhwalithi pre-bula. amandla Final is ushaye ngemuva kwamahora ambalwa.

Yesigcilikisha Epoxy ukulungiselela ezimbili ingxenye ngokucacile ukuba kufundiswe ngokuhambisana olinganise kuwo futhi ubambe isikhathi. Lapho ukusondelana kungenzeka izingxenye ezimbili isetshenziswa kwenye ingxenye Activator, kanye nezinye - resin. Lapho izingxenye yokuxhuma kuthiwa baxhumane ngendlela echazwe ngenhla.

Isicelo eyinhloko kokokunamathisela epoxy kuyinto izinto okungezona ukungena nakwamanye amazwe (ngaphandle zokwenziwa) ezidinga ngokuphephile ethe njo. Ukuze okukhulu amandla resin kungenzeka luqiniswe ngomhlanga-fiberglass. Le nqubo kusivumela ukuxazulula izinkinga ezinzima eziqhamukayo, ezifana ukulungisa imishini. Ngezinye izikhathi ingcina ezimbili ingxenye sengezwe ingxenye eliphezulu powder metal futhi wabasebenzisa njengezinceku Welding abandayo. United ngaleyo ndlela izinto ziye zanda amandla.

Ukuze okuhlala isikhathi eside ikakhulukazi nokunokwethenjelwa kweqiniso ezimbili ingxenye polyurethane ingcina, elisetshenziswa cishe kunoma iyiphi indawo. It ngokuphelele ithobela ematheni lesikhumba amalunga, izakhi sokhuni (kuhlanganise esindayo), aluminium, ingilazi, zensimbi, itshe yemvelo. Lokhu ingcina ezimbili ingxenye akesabi umswakama, ngakho kulungele umsebenzi wokwakha amakamelo nge umswakama high (isib egumbini lokugezela, okugeza nokunye. D.). Luhle umsebenzi exhunywe ne kubekwa amathayili (okubandakanya ukulayisha izithombe kanye yamatshe), ngoba gluing joinery, ngamatshe mbumbulu.

Ngenxa ingcina polyurethane, ebeka "phansi efudumele" uhlelo hhayi kuphela konga isikhathi, kodwa futhi imali namandla. Kungakhathaliseki ukuthi uhlobo isigubungelo phansi, kakade ngemuva kwamahora ayisishiyagalombili, awukwazi nje ukuhamba ngayo, kodwa futhi ahlele ifenisha. Lokhu ingcina (njengoba kuqhathaniswa Analog) cishe nokunwebeka, futhi ngenxa yalokho akusho oluhlehlela futhi akusho yokwelula. Lezi zimfanelo ayagcinwa ngisho ngaphansi komthwalo ijulile kakhulu.

Lokho nokwethenjelwa ingenye main nenqubo yokukhetha ngoba izicathulo izimboni kanye bezicathulo encane. Kungakhathaliseki isakhiwo yedwa (PVC, ukungena nakwamanye amazwe, njalo njalo. D.), Polyurethane ingcina izicathulo ithumba ebusweni kakhulu ukuze singawanyathela emva omiswe akunakwenzeka. Lezi zicathulo asesabi imvula, kunikeza kalula, zokunethezeka nenjabulo.

Two-ingxenye anamathelayo (polyurethane, epoxy) ikakhulukazi ezinzima futhi iqine, lemukelekako uthwebule imininingwane, ukuxhumana, amalunga kanye nozakwabo esikhundleni ngokuqiniseka. Zisetshenziswa cishe zonke izinhlobo umsebenzi, kungakhathaliseki ukuthi Izinga. Ceramics, zama-tile, isitini bamba "ukufa", yingakho labo aseke ayisebenzisa kokokunamathisela ezimbili ingxenye ekhethiwe futhi.
