Lub luag haujlwm ntawm polyvinyl wax hauv cov xim yog dab tsi? Polyethylene quav ciabua lub luag haujlwm ntawm lubricating thiab dispersing hauv cov pigment particle system, ua rau muaj kev sib raug zoo nrog cov resins xws li polyvinyl, polyvinyl chloride, polypropylene thiab lwm yam resins.
Thaum ntxiv rau hauv lub kaw lus xim particle,nws tuaj yeem ua rau kom muaj peev xwm ua kom cov xim sib xyaw ua ke, txhim kho kev ua haujlwm ntau lawm, thiab tib lub sijhawm ua kom cov xim ci thiab kev ua haujlwm ntawm cov khoom. Cov xim sib xyaw yog cov xim sib xyaw nrog cov resin ua tus nqa khoom. Cov xim muaj nyob rau hauv peb lub xeev: cov khoom tseem ceeb, cov khoom sib sau ua ke thiab cov khoom sib sau ua ke. Lub tshuab faib tawm ntawm cov xim yog kom tawg cov khoom sib sau ua ke rau hauv cov khoom sib sau ua ke thiab cov khoom tseem ceeb. Thiab cov txheej txheem ntawm kev ruaj khov cov khoom tsim tawm.
Cov resin yaj muaj viscosity siab thiab tsis sib xws nrog cov xim nto, yog li nws muaj qhov tsis zoo ntawm kev ntub dej thiab nyuaj rau nkag mus rau hauv cov qhov hws ntawm cov pob zeb sib sau ua ke, yog li nws tsis tuaj yeem xa lub zog shear zoo dua thiab nws nyuaj rau tawg cov pob zeb sib sau ua ke zoo. Txawm tias tom qab cov pob zeb sib sau ua ke tawg lawm, cov roj hmab yaj tsis tuaj yeem ntub sai thiab tiv thaiv qhov chaw, thiab kev sib tsoo thiab kev sib cuag nrog ib leeg yuav ua rau cov khoom me me rov sib sau ua ke. Txhawm rau daws qhov teeb meem no, ib qho nyiaj ntawm polyvinyl wax tuaj yeem ntxiv rau hauv qhov system saum toj no.
Cov txiaj ntsig ntawm daim ntawv thov ntawm polyethylene wax (PE Wax) hauv xim masterbatch:
(1) Polyethylene siv quav ciab nrog kev ruaj khov thermal siab dua muaj kev ruaj khov thermal zoo dua,vim tias yog tias cov khoom siv quav ciab raug roj, nws yuav muaj kev cuam tshuam tsis zoo rau cov xim thiab cov khoom lag luam, thiab muaj qee yam khoom tsis raug, Piv txwv li, tom qab qhov kev sim poob phaus thermal ntawm cov quav ciab pob zeb ntawm 200 ° C, cov quav ciab pob zeb yuav poob 10% ntawm nws qhov hnyav hauv 4 feeb, thiab qhov hnyav poob yuav ncav cuag ntau dua 20% hauv 10 feeb, yog li qee cov polyolefins pheej yig yuav poob phaus. Ntxiv qee cov khoom qis-molecular-weight xws li cov quav ciab pob zeb yuav muaj qee qhov cuam tshuam rau qhov zoo ntawm cov nplej toner thiab cov khoom lag luam tom qab ua tiav.
(2) Qhov hnyav molecular tsim nyog Los ntawm kev sim dispersibility ntawm polyvinyl waxes nrog cov qhov hnyav molecular sib txawv, lub peev xwm ntawm cov quav ciab los cais cov xim maj mam nce ntxiv nrog rau qhov hnyav ntawm cov molecular. Rau cov txheej txheem tsim cov xim, qhov hnyav ntawm cov molecular yuav tsum tau xaiv Polyethylene quav ciab ntawm 3000 yog qhov tsim nyog dua.
(3) Kev faib tawm qhov hnyav molecular nqaim Kev faib tawm qhov hnyav molecular muaj qee yam cuam tshuam rau kev sib kis ntawm cov polyolefin waxesCov quav ciab uas muaj qhov faib tawm molecular nqaim muaj qhov sib kis tau zoo dua li cov uas muaj qhov faib tawm molecular dav.
Polyethylene wax (PE Wax) muaj kev sib raug zoo nrog toner, nws yooj yim rau ntub cov xim, thiab tuaj yeem nkag mus rau hauv sab hauv ...
