Yav dhau los, hauv kev tsim cov khoom sib sib zog nqus los yog cov khoom hnyav hnyav, txhua tus xav tias cov roj nplaum uas tsis muaj zog (EP) yog qhov kev xaiv zoo tshaj plaws los tiv thaiv pwm. Sulfur thiab chlorine EP additives muaj keeb kwm ntev ntawm kev sib xyaw rau hauv cov roj zoo kom txhim kho pwm lub neej. Tab sis nrog kev tshwm sim ntawm cov hlau tshiab-siab-lub zog steel thiab nruj kev tiv thaiv ib puag ncig, tus nqi ntawm EP roj-raws li lubricants tau txo qis, thiab txawm tias poob lag luam.
Tsim cov hlau muaj zog ntawm qhov kub siab, EP roj-raws li lubricants poob lawv lub peev xwm los muab lub cev pwm-tiv thaiv diaphragm hauv cov ntawv thov kub heev. Qhov kub thiab txias IRMCO siab polymer lubricants muab kev tiv thaiv tsim nyog. Raws li cov hlau deforms nyob rau hauv lub stamping tuag thiab kub nce, EP roj-raws li lubricants yuav nyias, thiab nyob rau hauv tej rooj plaub yuav mus txog ib tug flash point los yog kub hnyiab. IRMCO water-based stamping lubricants feem ntau pib txau nrog qhov sib xws tsawg dua. Raws li qhov kub nce thaum lub sij hawm tsim, nws ua thicker thiab tougher. Nyob rau hauv qhov tseeb, polymer huab cua kub lubricants yog "kub nrhiav" thiab yuav lo rau cov hlau, tsim ib tug diaphragm uas txo cov kev sib txhuam. Qhov kev tiv thaiv kev tiv thaiv no tswj kev sib txhuam thiab cov hlau ntws los ntawm kev tso cai rau lub workpiece kom nthuav dav yam tsis muaj kev sib tsoo thiab kev sib txuas thaum lub workpieces xav tau tshaj plaws. Nws tiv thaiv cov pwm zoo, ua kom lub neej ntev kev pab cuam ntawm pwm, thiab txhim kho lub zog ntawm lub stamping.
