Epoxy resin for ubucwebe kunye izivatho kuyo

Epoxy resin ngokuba izacholo kuyinto material yemichiza mihla ukuba ithandwa enkulu phakathi iinkosi ababangela izihombo ngesandla. unako ukuvelisa iimveliso ezifana ngokupheleleyo iglasi ukusuka ubunzima zeplastiki. look kakhulu enomtsalane ngezinto zendalo (cone, iintyatyambo ezomileyo, amagqabi, njalo-njalo), ezaliswe isilungiseleli seglosi ngaphaya.

Abantu abo ebona abantu kakuhle zinokuhonjiswa kwaye uyakuvuyela ekudaleni zonke iintlobo zobugcisa ngezandla zabo, wosondeza ndawonye ukuze bafunde ukuba izacholo epoxy, yintoni na imithetho kunye ubuqili ukusebenza naye. Njengenxalenye inqaku unika iklasi master encinane ngokwenza pendant.

Umxholo ukufunda

Igama elithi "intlaka" yaziwa ukunxulumana zizinto imvelaphi yendalo. Kodwa ke kule meko sithetha malunga imveliso yemichiza. Ngaphandle, i njengeceba i ulwelo transparent, elakhiwe ngekhaya inamacandelo amabini, intlaka kunye hardener.

Xa ukujoyina izinto iikhemikhali kusabela, polymerize omnye nomnye. Isiphumo epheleleyo nentlaka ephilisa. Ngaphambi polymerization kwi njengeceba ungadibanisa fillers eziqinileyo leyo ukutshintsha iimpawu izinto zeplastiki nto kweli cala.

Ezahlukahlukeneyo iiplastikhi elungisiweyo

Wenza epoxy resin ngezandla zabo phezu ngokusekelwe brand ezaziwayo-kakuhle imveliso yasekhaya ye glue - EKF kunye EAF. Uyakwazi uwuthenge kwiivenkile ekuthengiseni nezincedisi zasekhaya. zokubopha encinane 280g Ibiza malunga 70-80 engange.

Umlinganiselo yentlaka iguqulwe kwaye hardener kufuneka kuluhlu 8: 1 - 10: 1. inkqubo polymerization Chemical lwenzeka bushushu kwaye ithatha iiyure eziliqela. Kuba Ukuqinisa epheleleyo iza kuthatha iiyure ezili-12. A arhente enganyangekiyo for epoxy intlaka kuchaphazela izinga polymerization: elide ngaphezu yakhe ekwakhiweni, aziyeke ngokukhawuleza imilo le mveliso. Umlinganiselo amacandelo afunekayo ukulinganisa ngokuchanekileyo kakhulu - oko kuchaphazela ngqo kwiziphumo zokuphela konyaka.

Enye imveliso imboni yemichiza yasekhaya - epoxy intlaka ED-20. Ekubeni ukhululekile kakhulu ukusebenza ekhaya, kwaye ixabiso le nomtsalane (isiqingatha ixabiso EKF kunye EAF). A ethile okuphawulekayo ukuphakheja elikhulu: 6 kg 1 kg intlaka - hardener.

On sale uyakwazi ukufumana-component ezimbini iimveliso zemisebenzi yezandla amazwe. Ngokusekelwe kuwo, ukwenza iimveliso ogqwesileyo nentlaka epoxy. Ngaphandle izinto eziphambili ekrwada ezisebhokisini inokufumaneka iiglavu, yokulinganisa yeplastiki iikomityi, ngamaplanga intonga ibangele. Ezi khithi zibiza kakhulu kuyaphi kunezixhobo basekhaya. Umlinganiselo wokuxuba ngazo kungaba ezahlukeneyo kunene: 2: 1, 1: 1, okanye ngenye indlela. Kusenokwenzeka ukuba inani kuya kufuneka ukubala usebenzisa ifomula okhethekileyo. Enoba kunjalo, kufuneka ulandele iingcebiso lomenzi.

Lumka umsebenzi

Epoxy resin sisetyenziswa ngokubanzi yokwakha, imisebenzi umhombiso yaye ukushicilela imveliso. Ekrwada izinto ukulungiselela iinjongo zobugcisa kunempembelelo enamandla imichiza ivumba kunye komphunga ukubacaphukisa kwi isixokelelwano sokuphefumla. Xa sisebenza kunye nezinto mveliso ukusebenzisa izixhobo zokhuselo.

Epoxy resin kubavelisi izacholo kunye nemisebenzi bokuhombisa athembele akumenzi ukumlimaza. Nangona ukhuseleko kunjalo kufuneka ityeshelwe. Ngokuqhelekileyo, baye ulwazi oluneenkcukacha bezifakwe kuyo, kodwa iluncedo ukukhankanya ngoku. Ngoko ke amanyathelo xa usebenza zokwaleka chemical:

• ukuze intlaka zange ukufumana izandla zakho kunye imifinya yangaphakathi kufuneka basebenze iiglavu zerabha kunye lobe zokhuseleko;
• kwimeko arhente kwemichiza kokuwela umzimba ukuba kurhoxa ngoko nangoko lee nesikhumba ngamanzi kunye neendawo zoqhagamshelwano ngamanzi acocekileyo;
• Alinako kusetyenziselwa mveliso amanqaku intlaka zihlangana ukutya;
• abuyise indawo yokusebenzela igcwele zeplastiki ifilimu okanye ephepheni ;
• umsebenzi wenziwa kwindawo kakuhle umoya.

Kunye nolophu

Inkqubo polymerization ihamba inkululeko ubushushu. Ngenxa basabela kwemichiza le intlaka kunokuba ndinobushushu degrees 60. Olu phawu kufuneka iqwalaselwe xa ukhetha namagumbi ekhupha ngayo, kungakuhle ukuba ubushushu ezingatshiyo.

Pre-ubushushu amacandelo ukuqala ibalekisa inkqubo polymerization. Njengoko ubushushu ukwandisa kwandisa fluidity ye nokuncipha intlaka kunye viscosity yayo. Uchitha epoxy resin iinkcukacha ocolekileyo uya kube ngokukhawuleza kwaye ngcono, ukuba isicombululo kukuba preheat ku 25-30 ^C. ke, ukuba iqalise lokufaka kunye kuphela emva koko hardener.

Ukwehlisa lobushushu kunye ukufuma kwemfuneko kuchaphazela kakubi i polymerization. Phantsi kwezi meko inkqubo kungalindiswa kakhulu okanye hayi kwaphela ukufikelela esiphelweni.

Thina ukufezekisa uzinzo oyifunayo

Nangona resin epoxy ukuba izacholo wangena kule inyathelo polymerization, igcina iimpawu ulwelo viscous. Ukuba ukwethula lokufaka owomileyo yesisombululo, oko kuwa phantsi (isamente, gypsum) okanye ivuke kumphezulu (iitshiphusi umthi, ukhokho). Olu phawu kwezinto kufuneka ingqalelo xa kukhethwa sokubumba naxazisaba yinxalenye yalo.

aids isicelo

Ubunzima ephambili eya nazo kule nkqubo - umoya amaqamza. Ukuba uvumela umxube kuma kuba ezimbalwa okanye kancinane efudumeleyo kwakhe phezulu, ziyabuya phezulu. Ukuze balahle amadlu kokulandela ifomu, ungasebenzisa i wokuvungula eqhelekileyo. Ukuya resin epoxy ngezandla zabo ukufumana ukuyondelelana ogqibeleleyo, yenza eyothi umlambo obhityileyo ngokusebenzisa njengesisefo entle.

Xa sisebenza kunye njengeceba elula ukusebenzisa izixhobo ezilahlwayo ekuphekeni iinxalenye ngamnye umxube. afaneleka kahle le iingqayi njongo zeplastiki kwimveliso yobisi (iyogurt, bobisi). Ushu umxube iinkuni obutofotofo yeplanga kwi-ice cream.

Ukuze kuveliswe i idosi echanekileyo amacandelo, ungasebenzisa iisirinji zonyango ezahlukeneyo ngobukhulu. Qaphela ukuba kulo mzekelo, niwuzalise nentlaka epoxy kufuneka kwenziwe phezulu etankini. A hardener uchwethezelwe kungena isirinji ngendlela eqhelekileyo.

Ababu- ekubunjweni, kungakuhle ukuba nokuthambisa isixhobo isisombululo olukhuselayo. It buyisela ijeli petroleum eqhelekileyo okanye parquet yemastic. Faka umaleko obhityileyo kwaye asuse naluphi kwemfuneko nto leyo a kwasala cotton. Ukuba iifom ezenziwe abicah, polyethylene, okanye Plexiglas, i-pre-ukuthambisa ajikeleze abawadingi.

Thetha excipients

kwezithako Solid kunye ulwelo nempembelelo yintoni na afunyenwe ngenxa izihombo ezenziwe epoxy nentlaka. Eyona ezininzi eziqhele ukusetyenziswa ezi iinjongo udaka, isamente, itshokhwe, chips ngomthi okanye ubumenyemenye (spangles). Umxholo kwezithako kwi umxube iyonke - hayi ngaphezulu kwe-50%.

Le excipients owomileyo zinika iplastiki eqinileyo, kodwa krobo. plasticizers ulwelo zisetyenziselwa Nokwethisa luphawu ezingathandekiyo nokuphucula ductility lo mbandela. Le Ukongeza ilula kwaye ezingabizi kakhulu inokuba ioli kukaCastor. Ngokuqhelekileyo, elinye okanye amabini amathontsi kwanele.

Ukukhetha sisincoko ngenxa eyimveliso pendant

Yenza uhombiso oluthile kuya kusinceda ecacileyo epoxy intlaka for izacholo. Ngokomzekelo singakwazi ukuthatha i-component ezimbini composition eveliswe yinkampani French Gedeo Pebeo umthamo ml 150.

Material uxelisa ngokupheleleyo iglasi, kwaye isetyenziswa kuphela ukuvelisa ngokombingeleli, kodwa ngenxa Ipeyinti multi-umaleko, umphezulu umhombiso, ukubuyiselwa lwamathanda. Isiseko isicelo usenokuba iglasi, intsimbi, zomdongwe, lesilicon, iplastiki, iinkuni epeyintwe. Le-thaskbha sikhanya kakhulu, esha, kulula ukulungisa. Le mveliso ogqityiweyo luphawulwa ngamandla aphezulu kwaye akafuni yellow ngokuhamba kwexesha.
