May 05, 2019
Lub raj mis yas yog polyester, polyethylene, polypropylene ua cov khoom siv raw, ntxiv cov organic solvent, tom qab cov cua sov ua kom sov, los ntawm cov yas yas dhau los ntawm tshuab moulding, nyem, lossis txhaj tshuaj molding yas ntim.
Cov kua roj los yog cov khoom ntim pov tseg ntim pov tseg ntim xws li kev siv tshuaj thiab kho tsiaj. Lub taub ntim yas tsis yooj yim rau tawg, tsis muaj nqi, siab pom, zaub mov qib raw khoom thiab lwm yam. Muaj ntau txoj hauv kev los tsim polyethylene, ib qho ntawm feem ntau, yog ntawm 200 txog 300 degrees C siab kub thiab 1000 mus rau 2000 qhov chaw siab, lub ethylene polymerization mus rau hauv. Hauv polyethylene, tsis txhob doped nrog lwm cov tshuaj.
Ob qho tib si muaj kev ruaj khov siab, yog li tsis tas yuav muaj admixtures, yas tsim, thiab stabilizer thiab plasticizers feem ntau ua rau muaj tshuaj lom lossis lom. Cov fwj dej yas ntim puv los ntawm rab phom pwm tom qab qee qhov ntsuas kub ceev lub tshuab moulding, tuaj yeem ua tiav los ntawm billet, kuj tuaj yeem ncaj qha los ntawm kev txhaj tshuaj moulding tshuab moulding lub tshuab ua daim ntawv.
