Ukucima i-infrared - yintoni efunekayo kwaye yintoni ekhethekileyo?

Enye yeendlela eziphambili kunye nezikhawulezileyo zokuphilisa ukupenda kwiimeko zorhwebo yindlela yokwenziwa kwonyango lomkhiqizo nge-infrared radiation. Kule nto, isistim esithile esisetyenzisiweyo - ukomisa i-infrared. Kuzo iinkalo zobugcisa ukuba ixesha apho ipeyinti idla kuxhomekeke kumgangatho wepeyinti ngokubanzi. Yintoni yokomisa i-infrared kwaye yintoni ephawulekayo, ungayifumana apha kwaye ngoku.

Izindlela zokuphilisa upende

Okwangoku, kukho iindlela eziliqela apho izixhobo zeenjongo zoshishino zikhawuleza emva koko emva kokufaka umgca othile wepeyinti kubo:

· Convective (ngoncedo lomlambo oshushu).

· Ukutshabalalisa (ukusebenzisa i- infrared radiation).

Udibeneyo (ukudibanisa ezimbini zokuqala).

Phakathi kwabo, owona msebenzi uphezulu, yiyo- IR-ray. Ukumisa okungekhoyo (i-IRT kubandakanyeka) ikuvumela ukuba usebenze phantse zonke iintlobo zamapayipi kunye neengqungquthela, eziquka amanzi-asethi kunye ne-acrylic. Ngexesha elifanayo, ifowuni ivumela ukuba lukhuni ngakumbi kwinkqubo yokuqina kowokuqala okanye i-putty. Iimpawu ezifumana umbane ogqithiseleyo zidlulayo ukusuka kummandla wamanzi ukuya kwilizwe elomeleleyo, elibizwa ngokuba lukhuni, ngolwimi lweengcali. Kwaye inkqubo yonke ithatha imizuzu engama-5.

Izixhobo zobuGcisa

Ukutywa kwe-short-wave wave esebenza ngolu hlobo lulandelayo. Emva kokudibanisa isixhobo kumthombo wamandla (oku ngokuqhelekileyo ukusetyenziswa kwamanzi kagesi) kwisixhobo esicutshungulwayo, uluhlu oluphezulu lwepeyinti luqala ukutshisa, oluye luthintele ngokupheleleyo ukuphuma kwe-solvent. Oku kwenzekayo xa i-wave wave-drying infrared. Izixhobo ezide zentshukumo zihambisa amandla azo ngokufudumeza ukufudumala. Ngaloo ndlela, umthombo okhangela ubushushu kumgangatho wepende kunye nezixhobo zokugcoba zivutha ukushisa komda we-700-750 degrees Celsius, emva koko iqondo lokufudumala lento yokumisa ngokwayo landa kuphela kuma-40 degrees. Ngenxa yoko, ixesha lokupholisa le fowuni liza kuba limizuzu engama-15-20, ngelixa ukukhuniza imibala yepende kuyakufuneka ukuba uchithe ufike kwi-1-2 yemizuzu yexesha.

Ngendlela, ukushisa okufudumalayo kwiinkqubo zesikhala eside kunkulu kunokuba kufakwe amacebo amancinci. Ukomisa okunjalo kwe-infrared kungashushu ukufika kwi-1450 degrees Celsius. Ngenxa yoko, ukufudumeza kwento yokumisa kwandisa. Ngenxa yoko, uninzi lwamandla ashushu (kufika kuma-75 ekhulwini) olukhutshwa yilo fowuni aluwa phezulu, kodwa kumgca ophantsi wepeyinti, emva koko ukuqina kunokwenzeka nangaphandle kwengubo.

Ziyaphi na?

Ukomisa i-infrared yamanje kuyasetyenziswa kumacandelo amaninzi oqoqosho kunye nezoshishino, njengoko kunokukhawuleza ukuzisa imeko efunwayo malunga nantoni na impahla: i-MDF, imveliso yeglasi yokuhlobisa, izidumbu zeemoto zensimbi kunye nokunye okuninzi. Konke oku kwenza ukuba kubaluleke kakhulu kwimbala yezoshishino zemveliso kunye neendlela.
