Epoxy resin: sisixhobo sele onke amacandelo

Epoxy resin - esilolo nokumelana eliphezulu acid, iziseko kunye halogens. It is a oligomer zokwenziwa. Ingasetyenziswa odibanisa phantse nasiphi na isixhobo. Xa urhulumente ilulwelo a epoxy intlaka ecacileyo, nto leyo iba umbala omthubi-orenji, yaye emva ukuqaqadeka iba brawuni phantse ekhuselekileyo impilo. Nangona kunjalo, ukusetyenziswa kwayo apho kusenokuba kukho zoqhagamshelwano ezinokuba izinyibilikisi, sol-leachable iqhekeza engenakwenzeka. Xa urhulumente engamanzi ukuba ityhefu kakhulu, ngoko ukusetyenziswa kwayo kufuna ukunamathela uluhlu lwemithetho.

Kakade ke, ngenxa ekwakheni izitya okanye ezinye izinto eziza adibane ukutya okanye amanzi okusela, loo nto ayinakusetyenziswa le njongo, kukho ezinye izinto. Noko ke, ngenxa yokuba iimpawu zabo, lo nentlaka epoxy sisixhobo sele kuluhlu olubanzi kakhulu mveliso. isebenzisa ezimbini eziyintloko nendaba: njengoko iglu kunye ukumitha. Ngoncedo wayo ukukhusela nxamnye umhlwa of ngekhonkrithi, ngentsimbi, ngumngundo ukwenziwa, iintlobo iglu, nkqu indima ebaluleke kakhulu phantse onke amasebe zobunjineli. Epoxy resin kunye fiberglass abaqala izinto ekuveliseni iglasi ifayibha, leyo ngokubanzi asetyenziswe ekwakheni, boat- noshishino emoyeni. Kwakhona, owokuqala isetyenziselwa ukugcwalisa elektroniki nkqu kuyilo.

Epoxy resin isetyenziswa ngokubambisana kunye hardener. Apho unyango ubushushu nezingamkelekanga kwindawo basekhaya, ezithi zisetyenziswe kwiindibano ezincinane kweziyobisi ebandayo. Kwaye yeemveliso ezibalulekileyo, yenzelwe ukusebenza imithwalo aphezulu eme ndawonye onamandla bume bako - shushu ephilisa arhente. Kulo mzekelo, igridi luthe beqwalasele iimolekyuli Polymer. Ngaphezu koko, kukho nentlaka epoxy kwakunye hardeners, esenzelwe ngokukodwa iimeko ukufuma phezulu, amanzi amtyuba.

Ukusebenza ubomi bakhe, kufuneka kuqondwe ukuba nezixandileyo hardener yayo ukusabela exothermic, yaye inkulu ubunzima Polymer, kokukhona ubushushu eyenziwe. Kule uqhagamshelo kuyimfuneko ukukhetha inani lasekunene-arhente, kwaye masihambelane kunye nenjongo ukusetyenziswa, ngenxa yoko, kufuneka bafumane i uniform (akukho maqampu) oluqinileyo. Ngaphezu koko, indlela intlaka kunye hardener ayibuyiseki umva, yaye emva koko thermoset, thermoplastic ngokungafaniyo akakwazi inganyibiliki okanye ukuluhlakaza kwakhona umphumo. Izinto ziqhelekileyo nefikelelekayo ayengawokuphilisa izinto epoxy ngoku ingqalelo PEPA, DETA, nditeta, TEPA kunye №1 (hexamethylene diamine unyityilikiswa ethyl utywala). Ngenxa yokuba eqhelekileyo-component amabini antsonkothileyo - into kunokuba abuthathaka, luthambe uyandiswa ngokongeza kwelinye icandelwana. Le element ubizwa ngokuba "isilungisi nefuthe", oko usenokuba ikhemikali Ukwakhiwa ezahlukeneyo, ngokuxhomekeke kulo, babe neempawu ezithile. ekhemisi ntiyiso baye bafumanisa izixhobo kufuneka akwaziyo ukwenza zombini njenge hardener, kunye isilungisi nempembelelo.
