Nyob rau hauv lub tshav pob ntawm kev ua cov yas thiab cov khoom tsim, "kev thaiv", "siab coefficient ntawm kev sib txhuam," thiab "tsis zoo deg tiav" tau ntev peb qhov mob loj rau cov lag luam. Blown films nyuaj rau cais tom qab winding, thiab txhaj tshuaj - molded feem feem ntau lo thaum demolding. Slip masterbatch zoo txhim kho kev ua tau zoo thiab cov neeg siv kev paub dhau los, thiab tau siv dav hauv cov khoom yas xws li PE, PP, thiab PLA. Tsab ntawv xov xwm no yuav muab rau koj hauv - nkag siab tob txog cov haujlwm tseem ceeb thiab cov ntawv thov ntawm daim npav masterbatch.
I. Kev txhais thiab cov ntsiab lus tseem ceeb ntawmSlip Masterbatch
Slip masterbatch yog cov khoom siv ntxiv ua los ntawm kev siv cov khoom siv los ua cov khoom thauj, ua kom pom tseeb thiab sib xyaw ua ke cov neeg ua haujlwm plam ua ke nrog cov khoom siv xws li dispersants thiab antioxidants, los ntawm melt compounding, extrusion, thiab pelletizing. Nws tuaj yeem raug ntxiv ncaj qha rau cov ntaub ntawv yas yam tsis muaj kev ua haujlwm ntxiv, ua kom yooj yim rau cov txheej txheem sib xyaw ua ke thaum daws cov teeb meem tsis sib xws thiab yooj yim tawg paj cuam tshuam nrog cov neeg ua haujlwm dawb huv.
Nws cov khoom tseem ceeb muaj xws li:
Primary slip agents:Cov no txiav txim siab qhov ua tau zoo ntawm cov masterbatch. Cov hom tseem ceeb muaj xws li amides (oleamide, erucamide, stearamide), silicone -raws li tus neeg sawv cev, thiab waxes (polyethylene wax, montan wax). Ntawm lawv, amide slip agents yog siv dav hauv kev ua lag luam vim lawv cov nqi siab -kev ua tau zoo thiab cov txiaj ntsig tseem ceeb.
Carrier cob:Ua hauj lwm raws li "carrier" ntawm tus neeg sawv cev slip, nws yuav tsum muaj kev sib raug zoo nrog lub hom phiaj yas substrate. Cov neeg nqa khoom muaj xws li polyethylene (PE), polypropylene (PP), thiab polyester (PET), thiab tuaj yeem hloov kho tau yooj yim raws li cov ntawv thov hauv qab.
Auxiliary Cheebtsam:Dispersants txhim kho qhov sib txawv ntawm cov neeg ua hauj lwm hauv cov khoom thauj; antioxidants tiv thaiv thermo-oxidative degradation thaum ua; coupling agents txhim kho kev sib raug zoo nrog cov khoom siv hauv paus thiab txo qhov kev pheej hmoo ntawm kev tawg paj.
II. Core Functions ntawm Slip Masterbatch
Txo kev sib txhuam coefficient:Lub luag haujlwm tseem ceeb tshaj plaws ntawm slip masterbatch yog kom txo tau ob qho tib si dynamic thiab zoo li qub coefficients ntawm kev sib txhuam ntawm cov khoom yas. Piv txwv li, nyob rau hauv tshuab cua tshuab ntau lawm, PE zaj duab xis nrog slip masterbatch ntxiv tsis thaiv tom qab winding, tso cai rau smooth tom qab slitting thiab luam ntawv txheej txheem.
Txhim kho demolding kev ua tau zoo thiab txo cov khoom hnav:Rau kev txhaj tshuaj molding thiab extrusion khoom, slip masterbatch txo qhov adhesion ntawm cov yas yaj thiab pwm nto, ua rau demolding yooj yim dua thiab txo qhov xav tau kev tso tawm cov neeg ua haujlwm. Nyob rau tib lub sijhawm, nws txo qis kev sib txhuam ntawm cov yaj hauv cov khoom siv ua haujlwm, txo qis hnav ntawm cov ntsia hlau thiab cov thoob thiab txuas cov cuab yeej siv lub neej.
Txhim kho qhov chaw tiav:Slip masterbatch tsim ib txheej lubricating txheej ntawm cov khoom nto, txhim kho gloss thiab du tactile xav.
III. Daim ntawv thov tseem ceeb ntawm Slip Masterbatch
Kev lag luam zaj duab xis:Blown films (PE cling film, khw hnab zaj duab xis), cam khwb cia zaj duab xis (CPP / BOPP ntim films), thiab stretch films sawv cev rau qhov loj tshaj plaws daim ntawv thov, daws teeb meem xws li thaiv tom qab winding thiab tsis zoo printability.
Txhaj- cov khoom molded:Cov khoom siv hauv tsev, cov khoom siv hauv tsheb, thiab txhua hnub - siv cov khoom (tableware, cov khoom ua si), qhov uas nws txhim kho demolding efficiency thiab nto smoothness.
Cov kav dej thiab profiles:PE cov kav dej thiab PVC profiles (qhov rooj, qhov rais, laj kab), txo kev sib txhuam ntawm cov yaj thiab pwm thaum extrusion thiab txo qis sab hauv- phab ntsa roughness.
Ntim Cov Khoom Noj:Khoom noj khoom haus-hu rau- qib slip masterbatch (ua raws liFDAthiab GB 4806 tus qauv) tuaj yeem siv rau hauv cov zaub mov qhwv thiab laminated films kom muaj kev nyab xeeb.
IV. Tswv yim rau xaiv Slip Masterbatch
Xaiv txoj cai swb masterbatch yuav tsum tau txiav txim siab ntawm peb yam tseem ceeb -puag hom resin, daim ntawv thov khoom, thiab kev siv thev naus laus zis-thaum zam qhov kev xav tsis zoo tias "siab dua ntxiv txhais tau tias muaj txiaj ntsig zoo dua":
Match lub hauv paus cob kom paub meej tias compatibility:Slip masterbatches nrog cov nqa khoom sib txawv haum cov khoom sib txawv. PE-raws li masterbatches yog tsim rau PE thiab PP; PET-raws li masterbatches yog tsim rau PET fibers thiab films. PVC- tshwj xeeb slip masterbatches yuav tsum xav txog kev sib raug zoo nrog PVC thermal stabilizers kom tsis txhob muaj tshuaj lom neeg.
Xaiv tus neeg sawv cev daim npav hom raws li cov khoom xav tau:
High plam, tsis tshua muaj kev sib txhuam coefficient:Nyiam erucamide masterbatch, uas tsiv mus qeeb thiab muab kev ua haujlwm ntev -, haum rau cov yeeb yaj kiab tuab thiab cov khoom siv ruaj khov.
Fast - ua yeeb yam:Xaiv oleamide masterbatch, uas migrate sai thiab haum rau luv luv -slip xav tau ntawm nyias ntim zaj duab xis.
High- qhov kawg qhov yuav tsum tau muaj:Xaiv silicone-raws li daim nplaum masterbatch, muab siab gloss thiab tsis tshua muaj kev pheej hmoo tawg, zoo tagnrho rau tsheb thiab khoom siv hauv tsev.
Environmental thiab regulatory ua raws li:Rau cov ntim khoom noj, khoom siv kho mob, lossis cov khoom ua si menyuam yaus, xaiv cov ntawv nplaum masterbatch ua raws FDA, EU REACH, GB 4806, thiab lwm yam qauv kom tsis txhob muaj teeb meem kev tsiv teb tsaws.
Tswj cov koob tshuaj kom sib npaug ntawm kev ua haujlwm thiab tus nqi:Cov qib sib ntxiv ntawm 0.2% mus rau 2%, kho raws li cov khoom tuab thiab kev ua haujlwm. Kev sib ntxiv ntau dhau tuaj yeem ua rau lub ntsej muag tawg lossis "dawb haze," cuam tshuam rau daim ntawv adhesion; Kev sib ntxiv tsis txaus yuav ua tsis tau raws li qhov xav tau ntawm kev poob siab.
V. Kev ntseeg yuam kev thiab ceev faj
Misconception 1: Ntau dua ntxiv txhais tau tias kev ua haujlwm zoo dua.Kev siv tshuaj ntau dhau tuaj yeem ua rau tus neeg sawv cev plam tawg, ua kom tawv nqaij dawb, thiab teeb meem ink adhesion, thaum nce nqi ntau lawm. Kev sim me me - raug pom zoo los txiav txim siab qhov zoo tshaj plaws.
Misconception 2: Compatibility yuav tsum tau kuaj thaum siv antistatic los yogxim masterbatch.Qee cov tshuaj tiv thaiv kab mob tuaj yeem ua kom nrawm nrawm ntawm tus neeg sawv cev tsiv teb tsaws, ua rau cov khoom lag luam ntxov ntxov.
Kev xav txog kev khaws cia:Slip masterbatch yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo -ventilated warehouse kom tiv thaiv kom tsis txhob ya raws thiab caking, uas tuaj yeem cuam tshuam kev tawg thaum lub sijhawm ua haujlwm. Tom qab qhib, nws yuav tsum tau muab kaw kom sai kom tsis txhob muaj qhov sib ntxiv volatilization.
