Tambayoyin da ake yawan yi Game da Jayayyar Epoxy akan Farin Marmara
1. Me yasa epoxy ke juya rawaya akan farin marmara?
Epoxy na iya rawaya saboda tsufa na polymer da ke da alaƙa da bayyanar UV, zafi, oxidation, resin da hardener sunadarai, da sauran yanayin muhalli. Farin marmara yana sa ƙananan launuka suna iya gani sosai. Duk da haka, ba kowane yanki mai duhu ko launin launi ba shine ainihin launin rawaya na epoxy; wuce gona da iri, tabo, da inuwar gani na iya haifar da lahani iri ɗaya.
2. Akwai guduro epoxy gaba daya mara rawaya?
Ana iya siffanta samfuran kasuwanci azaman masu launin rawaya ko ƙananan rawaya, amma masu siye yakamata su fassara waɗannan sharuɗɗan a matsayin ingantacciyar kwanciyar hankali a ƙarƙashin ƙayyadaddun yanayi maimakon tabbacin cewa babu wani canji da zai taɓa faruwa. Don ayyukan da ake buƙata, kwatanta aikin tsufa kuma gwada cikakken tsarin resin-hardener akan ainihin farin marmara.
3. Wane epoxy ya kamata a yi amfani da shi don farin marmara mai wuya?
Hard farin marmara gabaɗaya yana fa'ida daga epoxy mai ƙarancin rawaya tare da sarrafawa mai sarrafawa, tsabta mai ƙarfi, da isasshen kwarara don ƙarfafa fashe masu kyau. Tsarin Veropoxy's 5090/D30M-BS an sanya shi musamman don farin marmara mai wuya kuma yana lissafin launin rawaya kaɗan, 400-600 CPS danko, rabo 100:30, kuma kusan warkewar mintuna 80 a kusa da 24°C.
4. Me yasa bayyananniyar epoxy ke haifar da alamar duhu akan farin marmara mai laushi?
Matsalar na iya zama wuce gona da iri fiye da yin rawaya. Guduro na iya canza yadda haske ke tafiya ta cikin marmara mara kyau, ƙirƙirar rigar kamanni ko duhu a kusa da yankin da aka yi magani. Don farin marmara mai laushi, yi amfani da tsarin da aka ƙera don shigar da sarrafawa da kuma halin rashin tabo.
5. Ta yaya masana'anta za su gwada epoxy kafin amfani da shi akan farin marmara?
Gwada epoxy akan ginshiƙan samarwa na wakilci a yanayin yanayin masana'anta. Yi rikodin rabon hadawa da adadin aikace-aikacen, duba iyakokin shiga, ba da damar cikakkiyar magani, goge bel ɗin ta amfani da tsari na yau da kullun, kuma kwatanta launi, haske, sautin rawaya, inuwa, gyara ganuwa, da sheki. Don ayyuka masu ƙima, ƙara kwatancen zafi ko gwajin tsufa na UV kafin yarda da yawa.
Yadda Ake Ci gaba da Gyaran Farin Marmara Tsawon Lokaci
Kwanciyar hankali na gani na dogon lokaci akan farin marmara ya dogara da fiye da bayyananniyar guduro. Tsarin epoxy mai nasara dole ne ya haɗu da sunadarai masu launin rawaya, shigar da sarrafawa, daidaitaccen magani, daidaitaccen haɗawa, da dacewa tare da takamaiman tsarin marmara. Masu saye ya kamata su yi hukunci da ƙãre da kuma tsufa dutse-ba kawai bayyanar epoxy ruwa a cikin akwati.
Da farko gano ainihin aibi
Yankin gyaran rawaya na iya nuna canza launin polymer, amma halo mai duhu zai iya fitowa daga wuce gona da iri, ragowar saman, canjin gani mai alaƙa da danshi, ko tabo. Kula da kowace matsala na gani a matsayin "rawaya" na iya haifar da masana'anta don canza canjin da ba daidai ba.
Daidaita guduro zuwa tsarin marmara
Hard, farin marmara mai yawa:
ba da fifikon sinadarai masu launin rawaya-ƙasa-ƙasa, nuna gaskiya, da isasshiyar shigar sarrafawa don ƙarfafa ƙananan fasa-kwari.
Farin marmara mai laushi ko mai laushi:
ba da fifikon halayen da ba tabo ba da kulawar shigar ciki don kada gyara ya haifar da halos mai duhu ko tasirin alamar ruwa.
Samar da yawan zafin jiki:
tabbatar da daidaiton launi da halayen warkewa a ainihin dutse da zafin jiki na bita.
Ayyukan da aka fallasa UV:
Nemi aikin tsufa masu dacewa ko gudanar da gwaje-gwajen kwatancen sarrafawa maimakon yanke hukunci kawai tsayuwar farko.
Filayen da aka goge masu ƙima:
duba guduro bayan cikakken warkewa da gogewa na ƙarshe saboda rigar bayyanar ita kaɗai ba zata iya tsinkayar tukwane da aka gama ba.
Me yasa gwajin samfurin ya fi mahimmanci akan farin marmara
Farin marmara iri-iri sun bambanta a cikin porosity, translucency, veining, tsarin tsagewa, da halayen sha. Gudun da aka yarda da gani akan dutse ɗaya na iya haifar da inuwa akan wani. Don haka ya kamata a yi amfani da bayanan mai ba da kaya don tantance samfuran, yayin da gwajin dutse ya kamata ya yanke shawarar amincewa ta ƙarshe.
Menene ke canzawa a cikin ƙwararrun sarrafa farin marmara?
ƙwararrun na'urori masu sarrafawa a hankali suna ƙauracewa daga jeri-na-yi-na-yi na “bayani mai haske” zuwa takamaiman tsarin aikace-aikace. Farin marmara mai yawa, farin marmara mai laushi, samar da yanayi mai dumi, manyan gine-ginen gine-gine, da abubuwan da aka fallasa UV kowanne yana sanya buƙatu daban-daban akan sinadarai na guduro da halayen shiga. Wannan yana sa bayanan aikace-aikacen, aikin tsufa, da cancantar samfurin su zama mahimman sassa na kimantawar mai kaya.
Practical Recommendation
Idan epoxy da kanta ya zama amber, ba da fifiko ga tsarin guduro mai daidaita launi da taurin. Idan marmara ta haɓaka halo mai duhu yayin da resin da aka warke ya kasance a sarari, rage shiga kuma bincika shayar da dutse. Idan zafin jiki ko bayyanar UV yayi girma, cancanci tsarin ƙarƙashin waɗannan ainihin yanayin. Idan tsaftar gani yana da mahimmanci, gwada kan marmara na gaske, kammala aikin warkewa da gogewa na yau da kullun, sannan a kwatanta shingen da aka gama kafin amincewa da wadatar da yawa. Mafi kyawun farin marmara epoxy ba wai kawai mafi tsabtataccen ruwa ba ne - shine tsarin da ya kasance mai tasiri sosai kuma ba tare da gani ba a duk lokacin sarrafawa da sabis.
Kuna Bukatar Gwaji Tsarin Epoxy akan Farin Marble ɗinku?
Farin marmara ya bambanta sosai a cikin yawa, porosity, translucency, da tsaga. Kafin siyan da yawa, gwada epoxy akan ainihin Carrara, Calacatta, Statuario, ko wani farin marmara kuma kimanta shigar ciki, rawaya, inuwa, yanayin warkarwa, da gogewar bayyanar a ƙarƙashin yanayin masana'anta na gaske.
