Kev xaiv Mould Release Agent yog ib kauj ruam tseem ceeb hauv kev tsim cov ntsiav tshuaj trichloroisocyanuric acid (TCCA), uas cuam tshuam ncaj qha rau kev tsim cov ntsiav tshuaj, kev ua haujlwm ntau lawm, thiab cov nqi kho pwm.
1 、 Lub luag haujlwm ntawm pwm tso tawm tus neeg sawv cev
Pwm tso tawm cov neeg ua haujlwm feem ntau yog siv los tsim cov yeeb yaj kiab nyias ntawm cov pwm thiab TCCA ntsiav tshuaj, kom yooj yim rau kev tshem tawm cov khoom los ntawm cov pwm, thaum txo cov pwm hnav thiab muaj kuab paug.
2, Xaiv txoj cai ntawm pwm tso tus neeg sawv cev
1). Khoom siv compatibility:
Xaiv cov pwm tso tawm tus neeg sawv cev uas sib haum nrog TCCA ntsiav tshuaj kom tsis txhob muaj tshuaj lom neeg los yog muaj kab mob ntawm cov khoom.
2). Cov nyhuv demoulding:
Xyuas kom meej tias cov pwm tso tawm tus neeg sawv cev muaj cov txiaj ntsig zoo demolding, kom TCCA cov ntsiav tshuaj tuaj yeem ua tiav thiab tawm ntawm cov pwm.
3. Hom pwm tso tawm tus neeg sawv cev
1). Boric acid
Zoo thiab solubility:
Boric acid yog dawb, yooj yim ntws siv lead ua los yog hmoov uas yog soluble nyob rau hauv ntau yam kuab tshuaj xws li dej, cawv, thiab glycerol. Qhov dej zoo solubility no ua rau boric acid yog ib qho khoom siv ntau heev hauv kev npaj cov pwm tso tawm cov neeg ua haujlwm.
Kev ua haujlwm:
Anti corrosion thiab antibacterial zog: Boric acid muaj zog antibacterial thiab anti-corrosion zog, uas yuav txo tau qhov cuam tshuam ntawm corrosion yam ntawm pwm thiab prolong lub active lub neej ntawm pwm.
Thickening: Boric acid tuaj yeem ua kom tuab cov neeg tso tawm yam tsis muaj kev cuam tshuam rau nws cov txiaj ntsig, ua kom yooj yim rau tus neeg tso tawm kom ua raws li cov pwm pwm thiab txhim kho kev tso tawm.
Kho tus nqi pH: Hauv kev lag luam tshuaj tua kab mob, boric acid hauv ntsiav tshuaj kuj yog siv los kho tus nqi pH.
Cov khoom zoo boric acid feem ntau muaj cov yam ntxwv ntawm cov khoom me me, yooj yim dispersion, yooj yim dissolution, thiab nplawm, thiab muaj cov kev cai nruj rau dryness, fineness, thiab caking.
2). Magnesium stearate
Cov tsos thiab solubility:
Magnesium stearate muaj cov hmoov dawb zoo li thiab zoo nkaus li zoo. Nws yog insoluble hauv dej thiab ethanol, tab sis soluble hauv dej kub thiab ethanol. Thaum raug cov kua qaub, nws decomposes rau hauv stearic acid thiab coj magnesium ntsev.
Kev ua haujlwm:
Thaum lub sij hawm cov ntsiav tshuaj nias txheej txheem, magnesium stearate yog siv los ua tus neeg sawv cev tso tawm, nrog ntau npaum li cas. Nws kuj yog siv los ua tus neeg sawv cev tiv thaiv kab mob, emulsifier thiab / ora stabilizer.
Vim nws qhov xwm txheej tsis zoo nyob hauv dej, magnesium stearate tuaj yeem tsim cov khoom nplaum nplaum hauv qee yam kev siv, uas tej zaum yuav muaj lub hnab cuam tshuam rau daim ntawv thov.
4. Daim ntawv thov hauv cov pwm tso tawm cov neeg ua haujlwm
boric acid: Raws li ib qho ntawm cov khoom ntawm tus neeg tso tawm, boric acid ho txhim kho kev ua haujlwm thiab lub neej ua haujlwm ntawm tus neeg tso tawm. Tshwj xeeb tshaj yog nyob rau hauv cov pwm tso tawm cov neeg ua haujlwm uas xav tau kev huv huv, siab transparency, qhov zoo ntawm boric acid yog pom tseeb dua.
Magnesium stearate: Txawm hais tias magnesium stearate kuj muaj lubrication zoo thiab demolding los, nws yuav raug txwv nyob rau hauv tej daim ntawv thov teb vim nws insoluble xwm nyob rau hauv dej. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau muab tso rau ntawm cov khoom huv si thiab pob tshab, magnesium stearate yuav tsis yog qhov kev xaiv zoo tshaj plaws.
Raws li CPO tus tswv cuab ntawm NSPF, peb tus kws tshaj lij tswj xyuas lub pas dej ua ke nrog cov xwm txheej zoo txhua hnub, peb muaj keeb kwm kev tshaj lij rau pas dej thiab dej khib nyiab rau ntau tshaj 29 xyoo. Tiv tauj peb kom paub meej daim ntawv thov thiab kev daws teeb meem hauv tus nqi-kev ua tau zoo tshaj plaws.
