Dab tsi yog qhov tshuab folding moulding nrog roj nplua nyeem? Yam roj nplaum yog dab tsi nquag siv? Koj yuav tsum xyuam xim thaum xaiv?
Cov kev ua ntawm cov roj nplaum yog kom txo cov txhuam ntawm cov yas macromolecules, txhim kho qhov dej ntawm cov polymer, txo cov kev sib txhuam ntawm cov polymer thiab cov tshuab ua, tsis txhob muaj qhov adhesion ntawm lawv, thiab txo cov kev npoo ntawm cov khoom.
Raws li cov kev ua ntawm lub roj nplua nyeem, nws muab faib ua lub roj nplua nyeem thiab lwm lub roj nplua nyeem. Sab hauv lub roj rau sab nrauv hais txog kev sib haum xeeb ntawm cov khoom siv thiab lub pob zeb, uas yuav ua kom cov dej ntawm cov khoom pov tseg thiab txo cov kev sib txhuam ntawm cov khoom pov tseg. hais txog qhov ntxiv ntawm cov pob txha los ua kom tsis txhob muaj cov khoom uas siv los ntawm cov khoom yas, thiab txo cov khoom sib xyaws thiab cov khoom ntim, thiab tiv thaiv cov khoom siv hlau tawm ntawm cov khoom siv hlau. ntau cov lubricants muaj ob hom roj nplua zog, xws li cov xuab zeb hlau.
Cov thermoplastic plastics uas yuav tsum ntxiv roj nplua nuj muaj xws li PVC, PP, PE, PS, PA, ABS, thiab lwm yam., Cov uas, polyvinyl chloride tsis tshua muaj qhov zoo tshaj plaws.Qhov feem ntau siv cov tshuaj ntxuav tes muaj xws li cov xuab zeb hlau, cov roj carbon monoxide, lawv cov ntsev thiab cov ntsev fatty acid.Yog hais tias stearic acid (octadecanic acid), kua roj (cov roj dawb), polyethylene wax (tsis tshua muaj pes tsawg molecular polyethylene), stearic acid amide, oleic acid amide.
Cov teeb meem nram qab no yuav tsum raug sau tseg thaum xaiv cov roj nplua nyeem.
(1) lub roj nplaum yuav tsum tau tshaj li daim tawv thiab lwm yam khoom siv.
(2) lub roj nplaum yuav ua rau tus kab mob sib kis tau zoo nyob rau hauv daim duab uas tsis cuam tshuam txog cov khoom ntawm cov khoom yas.
(3) nws tsis muaj kev cuam tshuam dab tsi ntawm qhov zoo ntawm cov khoom yas molded thiab yog qhov zoo rau kev txhim kho cov tsos ntawm cov khoom
Kev zoo thiab txo qis ntawm qhov chaw npau taws; Nws tsis ua kom zoo lossis tsis zoo nyob rau hauv qhov ntau ntawm qhov kub thiab txias
Nws nyob ntawm qhov kub thiab txias.
(4) lubricants ntawm kev ua haujlwm tib yam yuav tsum raug xaiv nrog tus nqi tsawg thiab ntau qhov chaw.
