Sida loo tijaabiyo dhumucda cajaladda

Waqtigan xaadirka ah, sheyga kaliya ee lagu tijaabiyo alaabada cajaladaha lagu xidho ee suuqa waa viscosity iyo dhumucda caaryada. Dhab ahaantii, viscosity ee cajaladda xidhidhku waxay inta badan ka kooban tahay saddex tilmaame: xidhiddeeda bilawga ah, qabsashada, iyo xoogga diirka. Kuwani sidoo kale waa saddexda shay ee aasaasiga ah ee lagu qeexay heerka qaranka ee tijaabada viscosity ee cajaladda xidhidhiyaha ama alaabta is-xabaga ah. Aaladaha u dhigma waxa lagu magacaabaa tijaabiyaha taaj ee bilowga ah, tijaabiyaha tack tester iyo tijaabiyaha diirka elegtarooniga ah (mashiinka tijaabinta xajinta). Waxa kale oo aad dooran kartaa qalabka tijaabinta cajaladda ee u dhigma iyadoo loo eegayo baahidaada. Cabbirka dhumucda filimka BOPP waa mid ka mid ah walxaha kormeerka aasaasiga ah ee warshadaha wax soo saarka filimada. Qaar ka mid ah tilmaamayaasha waxqabadka kale ee filimka ayaa la xiriira dhumucda. Sida iska cad, haddii dhumucdiisuna waxay ka mid ah filimada hal-lakabka ah ma aha labis, ma saamayn doono oo kaliya xoogga xajin iyo sifooyinka caqabada filimka, laakiin sidoo kale saamayn ku processing xiga ee filimka. Filimada isku dhafan, lebbiska dhumucda ayaa aad muhiim u ah. Kaliya marka dhumucda guud ay labbis tahay ayaa dhumucda lakab kasta oo resin noqon karaa labis. Sidaa darteed, haddii dhumucda filimku yahay mid la mid ah, haddii ay ku habboon tahay qiimaha horay loo dhigay, haddii dhumucdiisu ay ku jirto xadka la cayimay, dhammaantood waxay noqonayaan aasaaska haddii filimku yeelan karo sifooyin gaar ah. Waxaa jira laba nooc oo cabbirka dhumucda filimka: tijaabinta khadka iyo tijaabinta khadka ka baxsan. Midka ugu horreeya ee loo isticmaalo cabbiraadda dhumucda filimka waa tignoolajiyada cabbirka dhumucda khadka ka baxsan. Taas ka dib, iyada oo horumarinta joogtada ah ee tignoolajiyada rayiga, qalabka cabbiraadda dhumucda online-ka ah ee lagu rakibay khadka wax soo saarka filimka ayaa si tartiib tartiib ah loo sameeyay. Tignoolajiyada cabbiraadda dhumucda khadka tooska ah ayaa si weyn loo isticmaali jiray 1960-meeyadii, hadda waxay awood u leedahay in la ogaado dhumucda dahaarka qaarkood ee filim khafiif ah. Tignoolajiyada cabbiraadda dhumucda khadka on-line iyo tignoolajiyada cabbira dhumucda ka baxsan khadka ayaa gabi ahaanba ka duwan mabda'a tijaabada. Tiknoolajiyada cabbiraadda dhumucda khadka-line guud ahaan waxay isticmaashaa hababka cabbiraadda aan xidhiidhka ahayn sida tignoolajiyada rayiga, halka tignoolajiyada cabbiraadda dhumucda aan online-ka ahayn ay guud ahaan adeegsato hababka cabbiraadda makaanikada ama ay ku saleysan tahay tignoolajiyada hadda jirta ama soo saarista korantada. Habka cabbiraadda mabda'a sidoo kale waxay isticmaashaa tignoolajiyada cabbiraadda dhumucda indhaha iyo farsamada cabbirka dhumucda ultrasonic. 1. Cabbirka dhumucda khadka tooska ah Farsamooyinka cabbiraadda dhumucda khadka inta badan waxaa ka mid ah tignoolajiyada β-ray, tignoolajiyada raajada iyo tignoolajiyada infrared-ka dhow. 2. Cabbirka dhumucda khadka-off-ka-baxa Tignoolajiyada cabbiraadda dhumucda khadka-ka-baxsan waxay inta badan ka kooban tahay laba nooc: Habka cabbiraadda xidhiidhka iyo habka cabbiraadda aan xidhiidhka ahayn. Habka cabbiraadda xiriirku waa inta badan habka cabbiraadda farsamada. Habka cabbiraadda aan lala xidhiidhin waxa ka mid ah habka cabbirka indhaha iyo cabbirka hadda jira. Habka, habka cabbiraadda ultrasonic, iwm Sababtoo ah qiimaha hooseeya iyo cabbirka yar ee qalabka cabbiraadda dhumucdiisuna waxay leedahay tiro balaadhan oo ah codsiyada. Soosaarayaasha filimada, lebbiska dhumucda alaabtu waa mid ka mid ah tilmaamayaasha ugu muhiimsan. Si wax ku ool ah loo xakameeyo dhumucda alaabta, qalabka tijaabada dhumucda waa lagama maarmaan, laakiin nooca gaarka ah ee qalabka cabbiraadda dhumucda si ay u doortaan waxay ku xiran tahay arrimo ay ka mid yihiin nooca baakadaha jilicsan, shuruudaha soo-saaraha ee sinnaanta dhumucda, iyo imtixaanka kala duwan ee qalabka.
