Kev huv thiab nyab xeeb: Ua kua masterbatch, nrog nws lub xeev ua kua, tshem tawm tag nrho cov plua plav tsim thiab dispersion thaum lub sij hawm tsim khoom. Qhov no ua kom zoo dua qhov chaw ua haujlwm ib puag ncig thiab tiv thaiv kev ua pa ntawm kev noj qab haus huv thiab kev nyab xeeb ntawm cov neeg ua haujlwm, pab cov tuam txhab yooj yim tiv thaiv kev soj ntsuam ib puag ncig kom nruj.
Txhim kho xim zoo: Cov thev naus laus zis no, siv nanoscale dispersion (qhov loj me D90 tswj ntawm 290-310 nanometers), zoo heev txo qhov tsis xws luag xws li xim pob thiab streaks ntawm cov khoom nto. Cov xim sib txawv yog txhim kho los ntawm ntau dua 60%, thiab xim sib txawv ΔE ntawm cov khoom sib txawv tuaj yeem tswj tau nyob rau hauv 0.5, ua tiav cov xim zoo sib xws.
Txo Cov Nqi Siv Tag Nrho: Txawm hais tias chav tsev tus nqi ntawm cov kua masterbatch yog qhov siab, nws qhov sib ntxiv yog qhov tsawg kawg nkaus (feem ntau 0.2% ~ 0.6%, tsuas yog 20% ~ 50% ntawm cov nyiaj siv hauv cov tsoos masterbatches). Nws kuj tseem txuag lub sijhawm hloov xim (tshaj 70%) thiab cov khoom siv tu (kwv yees li 80%), txhim kho kev siv cov khoom siv thiab kev ua haujlwm tag nrho.
Ua kom yooj yim rau cov txheej txheem: Ua kua masterbatch tsis tas yuav premixing thiab granulation. Nws tuaj yeem muab ntxiv tau thiab ua kom muaj nuj nqis siv lub siab - lub twj tso kua mis ntsuas qhov tseeb. Nws tuaj yeem ncaj qha mus rau hauv cov kab ntau lawm, ua kom yooj yim rau cov txheej txheem ntau lawm thiab txo kev cia siab ntawm kev siv phau ntawv.
