Ipholiyesta resin kunye epoxy resin: ngokungafaniyo, iimpawu kunye nohlolo

Epoxy kwakunye ipholiyesta nentlaka, iiyantlukwano leyo eza kuxutyushwa kweli nqaku kwakucingwa ukuba udidi thermosetting. Oku kuthetha ukuba emva kokuba inkqubo Ukuqinisa abakwazi ukuba ibuyiselwe embusweni engamanzi. Zombini imixube babe neempawu ezahlukeneyo, nto leyo ebonisa imihlaba yabo. Ukuze siqonde injongo kwezi zinto uluncedo simazi kakuhle ngokutsha epoxy kwakunye ipholiyesta nentlaka.

epoxy

Epoxy ibhekisa kwimathiriyeli eziphuma zokwenziwa. Ngendlela esulungekileyo yinto ezifanele ukusetyenziswa njengoko sokuba i karhulumente okuqinileyo akakwazi. Ukuba ugalele le nentlaka epoxy kongezwe kwi olinganise ezichanekileyo hardener okhethekileyo.

Ngokuba ukusetyenziswa echanekileyo kubalulekile ukwazi iingenelo neengozi i nentlaka epoxy. Le resin yale hlobo kakhulu ngenxa iimpawu zayo amandla. Kuyinto iyamelana iikhemikali silwe ezifana asidi kunye alkalis. Izinto eziluncedo ze epoxy ziquka: shrinkage ngcathu, ukumelana phezulu wear, elide kakhulu. inkqubo Ukuqinisa lwenzeka phezu olubanzi uluhlu ubushushu, kodwa kuyacetyiswa sokuphila ukusuka degrees +18 ukuya +25. indlela Hot ugalele isetyenziswa ekwenziweni eyandileyo amandla ekwaziyo withstanding imithwalo obukhulu.

Olu hlobo nentlaka esetyenziswa kwishishini kwaye ekhaya. Umda ukusetyenziswa kwazo olindela ngokubanzi ngokudala ezaqanjwa ezintsha kunye nezakhiwo ubuhle. Ngenxa Ukuxutywa kweentlobo ezahlukeneyo nentlaka epoxy kwakunye hardeners ingaveliselwa imveliso yokugqibela ezineempawu ezingafani kakhulu.

Ukusebenzisa epoxy resin

uhlobo epoxy resin ikakhulu isetyenziswe Imathiriyeli imiphezulu nisondelelane: iinkuni, isikhumba, isinyithi kunye nabanye abasebenzi abanga-nakwamanye amazwe. Loo sisincoko afunwe elektroniki, ezobunjineli kunye moya. Fibreglass, ngenkuthalo asetyenziswe ekwakheni, nazo ezenziwe epoxy. Le resin esetyenziselwa imigangatho amanzi kunye neendonga, kuquka yangaphandle. Kugqityiwe iimveliso ezenziwe fiberglass, emva ukugaya kunye nokuqhutywa zithandwa kakhulu uhombiso lwe ngaphakathi kwizakhiwo.

arhente ephilisa for epoxy nentlaka

izinto epoxy iqulathe inamacandelo amabini, emva ukuxuba inkqubo polymerization iqala. Component ibangela Ukuqinisa le nentlaka epoxy kuthiwa hardener. Kuxhomekeka ukusetyenziswa nentlaka ezahlukeneyo kunye hardeners kunokuqulunqwa kakhulu ngokungafaniyo umxube epoxy.

Umlinganiselo yomenzeli ayengawokuphilisa kwi ekwakhiweni kuyohluka kwaye kuxhomekeke ikakhulu kwi bakala yentlaka. epoxy resin polymerization reaction ayibuyiseki umva, izinto oko baphele sele eqina akwenzeki.

Kuyinto yimpazamo bakholelwa ukuba xa kuma imali hardener yokuqaqadeka iya kuba ngokukhawuleza. Indlela esebenzayo ukukhawulezisa inkqubo - ukunyusa iqondo lobushushu mxube. Ukwandisa lobushushu ukusebenza degrees 10 ukukhawulezisa inkqubo izihlandlo ezi-3. Kukho amacandelo ezizodwa ezi iinjongo emarikeni. Kukho kwakhona ngumxube we epoxy, ukuqinisa kwiqondo lobushushu ezisezantsi.

Ukukhetha olungachanekanga isixa hardener kunempembelelo elibi kumgangatho imveliso ogqityiweyo. Ubukhulu becala kunciphisa amandla alo ukuxhathisa amachiza. Xa imali encinci hardener imithamo ezincangathi guquki, kunye agqithisile Polymer phezu eziphathekayo yabelwa. Olinganise kakhulu rhoqo intlaka / hardener ezi 1/2 okanye 1/1. Ngaphambi okuxuba, kucetyiswa ukuba ufunde imiyalelo icandelo ratio oluchanekileyo.

ipholiyesta resin

Loo resin senziwa nokusingatha alkoholi iinjongo ezizodwa. Izinto isisekelo ipholiyesta. izinyibilikisi ezizodwa kunye inhibitors kusetyenziswa ukukhawulezisa inkqubo ephilisa. Kuxhomekeka isicelo umbandela, ukuze akheke ezahlukeneyo kunye neepropati. Le mveliso ngenxa kufuneka olunye unyango ngenjongo yokuphucula ukhuselo emanzini kunye UV radiation. ngeso lenyama olongezelelweyo kwakhona uphucula iimpawu amandla imveliso. Ipholiyesta resin, epoxy ngokungafaniyo, zibandakanya iipropati mechanical ephantsi. Kodwa ke poliefirku enye eye ngexabiso eliphantsi, ngenxa apho izinto ixhaphake kakhulu.

emahlamvini ezinjalo zisetyenziswa kakhulu ekwakheni yokwakha, izithuthi, imikhumbi kunye nemveliso wesikhongozeli xa iikhompawundi chemical. components ipholiyesta xa exutywe iglasi ukwenza amandla compound eliphezulu. Ngenxa zezinto ezithile eziziphumo isetyenziswa ekwenziweni izikhuselo zeseyile, uphahla kwezakhiwo kunye nokukhanya.

Le resin ipholiyesta ifakiwe nayo ekwakhiweni welitye sokwenziwa. Wenza besebenzisa eli candelo zeplastiki lisetyenziswa ekwenziweni Ungqameko window, ukuvalwa ishawa, izahlulelo nezinto zokuhombisa. emahlamvini ipholiyesta, ngokungafaniyo epoxy, ngokulula luyawudyobha.

Eyona engundoqo eziluncedo lohlobo ipholiyesta nentlaka

Ipholiyesta resin, ngokungafaniyo epoxy, kukho usizo enkulu. Emva okuxuba, ubume yeglasi uba iimpawu amandla, ngaphezu iimpawu ngentsimbi. Ngokuba lukhuni poliefirki kufuna akukho iimeko ezizodwa kunye namaqondo. Sebenza kunye nayo zithathwa abasebenzi-olunzulu ngaphantsi, yaye umbandela ayibizi kakhulu.

Yintoni umahluko?

Ukubuza lo mbuzo: "? Kukuphi na okulunge ngakumbi, poliefirka okanye epoxy", Kufuneka siqonde ukuba kutheni kwaye apho intlaka iyafuneka. Zombini ezi mathiriyeli nobubi zabo nangobubi, kwaye ukhetho lokugqibela kuxhomekeke imiqathango ukusetyenziswa, kwakunye nohlobo komhlaba apho intlaka iza kusetyenziswa.

Epoxy has ixabiso eliphezulu, kodwa ke ixesha elide ngakumbi. Ukuba iipropati kakhulu enamathelayo ngenxa yesimo inxibelelanisa ubume kumphezulu ezahlukeneyo. Epoxy resin ezahlukeneyo ukusuka kwimveliso ipholiyesta shrinkage okungenamsebenzi, iimpawu engcono mechanical nokuzabalazela ukunxiba.

Ngoko ke, ngokungafaniyo poliefirki, epoxy kufuneka ixesha elingakumbi Ukuqinisa, nto leyo ithintela inkqubo woveliso iinxalenye kulo mbandela. Ukusebenza kunye nentlaka onjalo lukhatshwa zokhuseleko esiba: xa besebenza kunye nezinto engamanzi kuyimfuneko ukusebenzisa iiglavu yokuphatha iimveliso eziqinileyo kufuneka baphefumla. Ingozi ayikho intlaka okungaka njengoko amacandelo kusetyenziswa ukwenza le s karhulumente okuqinileyo. Xa eqina phantsi kweemeko eliphezulu lobushushu kukho ithuba yokuphulukana izinto viscosity ukuba kudala iingxaki ezongezelelekileyo kumsebenzi.

Yintoni engcono resin, epoxy okanye ipholiyesta? Ukuphonononga bathi kwiimeko ezininzi, owokuqala isetyenziswa iglu, njengokuba izulu liwuphakamele kakhulu kunolo nesixhobo ipholiyesta iimpawu zayo. Kwezinye iimeko, into evakalayo nenengqiqo kakhulu ukuba ukusebenzisa i uhlobo resin ipholiyesta, leyo, okokuqala, ndibasindise, yaye okwesibini, lula umsebenzi.

Izinto eziluncedo ukusebenzisa poliefirki

Poliefirka ukukhipha izinto eziyityhefu, kulula ukuyisebenzisa, nobuchule ukusebenza kungekho nto. Ukubunjwa esetyenziselwa enamathela iindawo ezahlukeneyo kunye processing elandelayo kuthetha, nto leyo eyandisa amandla. Ngokutsho iimpawu kwakuse of epoxy poliefirka oluphantsi kakhulu, kwaye sebenzisa ukuze kuncanyatheliswe indawo ngokungakhathali. Njengokuba material izinto zokuhombisa asihambelani kakuhle, njengoko has a iimpawu mechanical ephantsi. Xa ngokuxuba isimo poliefirki basebenzisa imali encinci kuvala. Material lukhuni ngokukhawuleza, kwisithuba seeyure 2-3.

Le piece ogqityiweyo yi elastic iyamelana ukugoba. Thabatha nemveliso nentlaka ipholiyesta yi Ukungabinakutsha. Ungaze usebenzise ipholiyesta intlaka ukuba inqaku ezenziwe epoxy. Ukuba bayihlaziye imveliso ye material epoxy kubhetele ukusebenzisa efanayo.

Indlela yokulungisa kakuhle kumphezulu

Le resin kufuneka isetyenziswe kuphela kumphezulu pre-ezilungiselelwe. Inyathelo lokuqala le ikhutshwa phandle usebenzisa bamafutha zesinyibilikisi. Emva kokususa kukungcola negrisi wokucoca inkqubo olwenziweyo. Ekubeni umphezulu eziphathekayo kunye sandpaper okanye isixhobo eyodwa topsheet onomzi. Emva koko, inkqubo ukususa uthuli. Emva koko, isicelo kunokwenzeka ukuqalisa icandelo ukusebenza.

uthintelo ingozi

Ukuze ukuba kubangela ukwenzakala xa sisebenza kunye nentlaka kunye hardeners, kuyimfuneko ukuba uthathe imiqathango ubuninzi. Ukungaphumeleli ukuthobela imithetho elula kungakhokelela kumonakalo ulusu, ukutsha okanye umsebenzi nokuphazamiseka zemiphunga xa usebenza epoxy okanye ipholiyesta nentlaka. Features yokhuseleko xa usebenza ngamachiza:

• Musa ukusebenzisa izikhongozeli ilungiselelwe zokupheka.
• Zonke zazo kufuneka lwenziwe impahla ezizodwa iiglavu. Phambi ukusebenza kwi sunscreen ingalo kufuneka isetyenziswe. Wokucoca kweemveliso ezigqityiweyo oluqhutywa baphefumla kunye iindondo ezizodwa.
• Kwimeko ye intlaka kokuwela eluswini kufuneka ihlanjwe ngesepha ngaphandle kokulibazisa okanye utywala acocekileyo.

Ukuphululwa macandelo epoxy kufuneka kwenziwe kwindawo kakuhle umoya.
