Cov lubricants sab hauv thiab sab nrauv ua si sib txawv hauv kev ua cov yas. Cov molecules ntawm lub lubricant sab hauv yog sib xws nrog cov yas polymer, thiab lawv tuaj yeem muab tso rau ntawm cov saw hlau molecular ntawm cov yas thaum cov yas yaj thaum ua, ua raws li "lubricant" los txo qhov kev sib txhuam ntawm cov saw hlau molecular, txo. lub cohesive quab yuam, thiab yog li txhim kho cov yaj flowability.
Cov lubricants sab nraud muaj qhov nro qis thiab qhov polarity tsis muaj zog, uas ua rau tsis zoo sib xws nrog cov yas molecules. Txawm li cas los xij, lawv tuaj yeem tsim cov yeeb yaj kiab sib cais ntawm cov yas yaj thiab cov hlau ntawm cov khoom siv ua haujlwm. Piv txwv li, paraffin tuaj yeem kis tau ntawm cov hlau saum npoo ntawm qhov kub thiab txias, tiv thaiv kev sib cuag ncaj qha ntawm cov yaj thiab cov hlau, yog li txo cov kev sib txhuam coefficient ntawm cov yaj thiab cov khoom siv. Qhov no pab txhawb kev nkag ntawm cov khoom siv rau hauv pwm kab noj hniav thaum lub sij hawm txhaj tshuaj molding thiab ua kom yooj yim demolding. Nws kuj tseem txo cov khoom siv, stabilizes ua qhov kub thiab txias, thiab tseem ceeb heev rau kev ua cov khoom siv hluav taws xob kub-rhiab.
Qhov zoo ntawm Zhongmai Roj Hmab thiab Yas Co., Ltd. lub lubricants sab hauv thiab sab nraud yog qhov tseem ceeb. Internal lubricants tuaj yeem txhim kho qhov kev sib txhuam sab hauv ntawm cov yas molecules, txhim kho plasticization efficiency thiab cov khoom ua tau zoo. Cov lubricants sab nrauv tsim cov yeeb yaj kiab uas muaj zog ntawm cov yas thiab cov khoom siv, txo cov adhesion thiab hnav, ua kom cov txheej txheem du thiab yooj yim demolding, yog li txo cov nqi thiab nce kev ua haujlwm rau cov lag luam yas, nrog kev ruaj ntseg zoo.
