Imfuno yentengiso ebanzi kunye neengeniso eziphezulu zikhuthaza uphuhliso olukhawulezayo lweshishini lezixhobo zombane ezincinci zasekhaya, imigca yemveliso ibikho kuyo yonke i-rice cooker, i-induction cooker, ipani yokuqhotsa yombane, isomisi seenwele kunye neketile yombane, izixhobo ezincinci zasekhaya ziye zaba yimfuneko kwiintsapho zanamhlanje.Uninzi lwezixhobo zekhaya ezincinci zisebenza kwindawo yobushushu obuphezulu, ukwenzela ukukhusela ngcono iindawo zayo zokusebenza ezahlukeneyo, i-coating nayo ibeka phambili ukusebenza okusisiseko kobushushu obuphezulu kunye nokumelana nokunxiba.Kwangaxeshanye ngcono ukuhombisa kunye nokunye ukusebenza kunokuhlangabezana ngcono neemfuno zemarike.
Enye, i-silicone yokugqoka
Ukwaleka kweSilicone yenye yezona zinto zakuqala kwaye zisetyenziswa kakhulu ukuxhathisa ubushushu obuphezulu kwizinto zombane ezincinci zasekhaya eTshayina.Ukwaleka kweSilicone ubukhulu becala yenziwe ngeresin yesilicone njengeyona nto iphambili, i-silicone resin ibonisa uthungelwano oluntsonkothileyo lwesakhiwo, iipropathi ezizinzileyo zeekhemikhali, ukumelana nobushushu obuphezulu.Ubushushu bokusebenza kwezona zixhobo zincinci zasekhaya zihlala zingaphantsi kwe-300 ℃, kwaye ubushushu obuphezulu bokumelana ne-silicone yokwambathisa kunokufikelela kuma-300 ℃.Ngokwembono yokusebenza kokumelana nobushushu, ukugquma kwe-silicone kukufanele kakhulu ukugquma ubushushu obuphezulu kwizixhobo ezincinci zendlu.
Ukuze kuhlangatyezwane neemfuno zesixhobo esincinci sasekhaya esisebenzayo esingaphezulu kwe-300 ℃, abavelisi bepeyinti yokuguqulwa kwe-silicon ye-organic, umgaqo osisiseko wokuguqulwa kukunciphisa izithako ezichasene nobushushu obuphezulu njengomxholo we-hydroxyl, ukwanda kweSi - O - Izitshixo ze-Si kunye nomlinganiselo wezinto ezinganyangekiyo kubushushu obuphezulu, zidityaniswe netekhnoloji yanamhlanje ehlanganisiweyo yokwenziwa kwezinto, Ukumelana nobushushu obuphezulu be-silicone yokwambathisa kuphuculwe kakhulu, ukuya kuthi ga kwi-600 ℃.
Ukufakwa kwe-silicone akugcini nje ukuchasana nobushushu obuphezulu, kodwa kunye nokubambelela okuqinileyo, ubunzima bokugquma okuphezulu, inkqubo elula kunye neendleko eziphantsi.Ezi zibonelelo zenza ukuba i-silicone yokwetyisa ikhanye kwimakethi yasekhaya yezixhobo ezincinci zendlu kwaye ithandwa ngamashishini amancinci asekhaya.Kodwa iintsilelo zokugquma abicah nazo ziyabonakala, ngakumbi kule miba ilandelayo:
(1) ukuncama umva.Ingubo elungiselelwe yi-silicone yokugqoka iqiniswe kwi-molecular thermal motion kwiqondo lokushisa eliphezulu, kwaye isakhiwo siya kuthamba.Xa unxibelelana nezinto ezibukhali, i-silicone yokugqoka efakwe kumphezulu wezixhobo ezincinci zendlu zixhomekeke kwimikrwelo kunye nomnye umonakalo kwi-coating phenomenon.
(2) Imiba yokhuseleko.Kukho izinto ezinobuthi ezinobuthi kwi-silicone yokugqoka, eya kuthi ngokuthe ngcembe isasazeke ukusuka ngaphakathi ukuya phezulu ngokungena ngaphakathi, ngokukodwa ukugubungela ngokuthe ngqo ngokutya, kunokubakho iingozi zokhuseleko lokutya;
(3) Ukumelana nobushushu obuphezulu.Ngokuphuculwa ngakumbi kobushushu bokusetyenziswa kwezinye izixhobo zasekhaya, iqondo lobushushu elisebenzayo lezixhobo ezincinci zendlu lide lifikelele kuma-600 ℃, indlela yokuphucula ngakumbi ubushushu bokusebenzisa i-silicone yokwaleka iye yaba yingxaki engxamisekileyo ukuba isonjululwe.Okwangoku, inani elincinci labavelisi abakhulu be-silicone abanamandla e-r & d baqhuba uphando olufanelekileyo kwaye benze inkqubela phambili, kodwa kusekho indlela ende yokuhamba ukusuka kwisicelo esisebenzayo.
Emibini, ukutyabeka nge-fluorocarbon
Ukugquma kweFluorocarbon, njengesixhobo esitsha, akuzange kusetyenziswe ixesha elide ekhaya nakwamanye amazwe, kodwa ukuxhathisa okuncomekayo kobushushu obuphezulu, ukuxhathisa okuqinileyo kwe-corrosion, ukuzicoca, ukubambelela ngamandla kunye nokumelana nemozulu ephezulu kuye kwaxhalabisa ngokubanzi.I-Fluorocarbon coating iyona nxalenye ephambili ye-fluorine resin, iimpawu zayo zeekhemikhali zizinzile kakhulu, zibalaseleyo ukumelana nobushushu obuphezulu.Izixhobo ezincinci zendlu ezigqunywe nge-fluorocarbon ziyakwazi ukuqhubeka zisetyenziswa kwindawo ye-260 ℃ ngaphandle kotshintsho, kunye ne-fluorocarbon coating ayinyibiliki kwioli, ayiyi kusabela ngokutya, ukhuseleko oluhle.Iinzuzo zokugquma i-fluorocarbon ziyabonakala, kodwa izinto ezingeloncedo nazo zivelele kakhulu.Ukusilela kwayo kubonakaliswa ikakhulu ekuchaseni ubushushu bayo, ubunzima kunye nokwakhiwa kwemiba emithathu.Ukuqina kwengubo ye-fluorocarbon kubushushu obuqhelekileyo yi-2-3h kuphela, oko kukuthi, ukutyabeka kwe-fluorocarbon kubushushu obuqhelekileyo akufuneki umhlakulo, ibrashi yocingo lwentsimbi, okanye nje ngeminwe inokukrwela ukutyabeka kwe-fluorocarbon, njengokwaleka kwe-fluorocarbon. kusetyenziswa iintsimbi zombane ukuhlangabezana amaqhosha kunye nezinye izinto ezibukhali kaninzi kubonakala imikrwelo umonakalo ukoleka isenzeko.Iingubo zeFluorocarbon zingasebenza ngokuzinzileyo kwindawo engange 260℃, kwaye ithande ukunyibilika xa ubushushu bungaphezulu koku.Ubunzima obuphantsi be-fluorocarbon coating bumisela ubunzima be-fluorocarbon coating ekwakhiweni kunye neemeko zobuchwepheshe.Indlela yokugcina i-adhesion kunye nokugudiswa kwengubo ye-fluorocarbon kwinkqubo yokudibanisa kubaluleke kakhulu.Isalathiso sophuhliso lwexesha elizayo lomgangatho ophezulu we-fluorocarbon coating:
(1) Sombulula i-solvent-based based resistance resistance, ubulukhuni kunye neemeko zokwakha ezinzima kunye nezinye iingxaki;
(2) ukukhuselwa kokusingqongileyo okuluhlaza ukutyabeka ngefluorocarbon emanzini;
(3) I-Composite ye-nanomaterials kunye neengubo ze-fluorocarbon zokuphucula ukuxinana kweengubo kunye nezinye izinto ezibanzi.
Isithathu, ukugquma umgubo
Iingubo zePowder ziye zaqatshelwa ngokubanzi njenge "Ubuchule, ubunzulu, i-Ecology kunye noQoqosho" ngenxa yeenzuzo zabo zokungabi ne-solvent ye-organic, akukho ngcoliseko, izinga eliphezulu lokusetyenziswa kunye nokusetyenziswa kwamandla aphantsi.Iingubo zomgubo zinokwahlulwa zibe yi-thermoplastic powder coatings kunye ne-thermosetting powder coatings ngokwezinto ezahlukeneyo zokwenza ifilimu.Esona sixhobo sincinci sasekhaya sisetyenziswa ngokuqhelekileyo kubushushu obuqinileyo bemodeli yomgubo wokugquma, umgaqo wayo kukusebenzisa intlaka enobunzima obuncinane bemolekyuli kunye nearhente yokunyanga ukuvelisa ukusabela kokudibanisa okunqamlezayo ukwenza i-reticulate macromolecule yokwambathisa kwisenzo sobushushu obuphezulu.Kwintsimi yezixhobo ezincinci zendlu, i-polyester yomgubo we-polyester, i-acrylic yomgubo we-acrylic, i-epoxy powder yokwambathisa kunye ne-polyurethane yomgubo isetyenziswa kakhulu.Iingubo zomgubo ziphuhliswe ngokukhawuleza kwiminyaka yamuva nje, kunye neentlobo ezininzi kunye nokusebenza okungcono.Iindleko zokusebenzisa umgubo wokugquma zisephezulu kakhulu kwizixhobo ezincinci zasekhaya ezinexabiso eliphantsi.Kuyathenjwa ukuba abavelisi bokwambathisa banokuphuhlisa ixabiso eliphantsi kunye nokusebenza okuphezulu komgubo wokugquma olungele izixhobo ezincinci zendlu.
Ukukhanya kwe-Ultraviolet (UV) okuphilisayo kukwavela kwimarike ngoku, umgaqo wayo kukusebenzisa ukukhanya kwe-ultraviolet ukukhuthaza ifotonitiator ukwenza i-photosensitive resin unsaturated key group reaction cross-linking reaction to form the structure of the coating.Nangona inkqubo yokuvelisa i-UV-curable coating ilula, iyabiza kwaye ukuzinza kwe-thermal ye-coating ayifanelekanga, ngoko ayikwazi ukusetyenziswa ngokubanzi kwimveliso yezixhobo ezincinci zendlu.
