Kev xaiv ntawm pwm tso tawm yog ib kauj ruam tseem ceeb hauv kev tsim cov ntsiav tshuaj acid (TCCA) muaj peev xwm ua tau zoo rau cov ntsiav tshuaj tsim nyog, ntau lawm, thiab kev txij nkawm pwm.
1, lub luag haujlwm ntawm pwm tso tawm
Cov neeg sawv cev tuaj pwm feem ntau yog siv los ua ib qho duab nyias nyias ntawm cov khoom lag luam thiab TCCA du ntawm cov khoom lag luam los ntawm cov khoom lag luam, thaum txo pwm pwm thiab muaj kuab paug.
2, Xaiv lub hauv paus ntsiab lus ntawm cov pwm tso tawm
1). Cov khoom siv tau:
Xaiv cov neeg sawv cev pwm uas tau tshaj tawm TCCA ntsiav tshuaj kom tsis txhob muaj tshuaj lom neeg cov tshuaj tiv thaiv lossis paug ntawm cov khoom.
2). Demoulding OFF:
Nco ntsoov tias Mould tso tawm tus neeg sawv cev muaj qhov cuam tshuam zoo, yog li ntawd TCCA cov ntsiav tshuaj tuaj yeem ua tiav ntawm cov pwm.
3. Hom ntawm pwm tso tawm tus neeg sawv cev
1). Boric acid
Tsos thiab solubility:
Boric acid yog ib qho dawb, yooj yim ntws cov siv lead ua lossis hmoov uas yog solubents hauv ntau cov kuab tshuaj xws li dej, cawv, thiab glycerol. Cov dej ua yeeb yaj kiab no ua rau boric acid ib feem ntau heev nyob rau hauv kev npaj ntawm cov neeg sawv cev ntawm cov pwm.
Ua haujlwm:
Anti corrosion thiab cov tshuaj tua kabmob: boric acid muaj cov khoom siv tshuaj tua kab mob zoo nkauj, uas tuaj yeem txo qhov kev ua kom haum ntawm cov pwm thiab ntxig lub neej nquag ntawm cov pwm.
Thickening: boric acid tuaj yeem thicken tus neeg sawv cev tso tawm yam tsis muaj kev cuam tshuam rau tus neeg saib xyuas kev ua raws li cov pwm thiab txhim kho kev tso tawm ua tau zoo.
Kho PE Nqi: Hauv kev siv tshuaj tua kab mob, boric acid nyob rau hauv ntsiav tshuaj kuj tau siv los kho tus nqi pH.
High QE Boric acid feem ntau muaj cov yam ntxwv ntawm me me particle, thiab nplawm, thiab muaj qhov yuav tsum tau ua kom qhuav, zoo, thiab cem.
2). Magnesium stearate
Cov tsos thiab solubility:
Magnesium stearate muaj cov hmoov dawb thiab zoo nkauj. Nws yog insoluble hauv dej thiab ethanol, tab sis soluble hauv dej kub thiab ethanol. Thaum nthuav tawm cov kua qaub, nws decomposes rau hauv stearic acid thiab coj cov ntsev magnesium.
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 tshuaj ntau heev. Nws tseem raug siv los ua cov tshuaj tiv thaiv kev tiv thaiv, ib qho emulsifier thiab / aj stabilizer.
Vim nws cov khoom siv insoluble hauv dej, magnesium stearate yuav ua kom cov khoom nplaum ntab hauv qee cov ntawv thov, uas tej zaum muaj hnab cuam tshuam rau cov ntawv thov.
4. Daim ntawv thov hauv cov neeg sawv cev sib tw
Boric acid: raws li ib qho ntawm cov neeg sawv cev tso tawm, boric acid tseem txhim kho cov kev ua tau zoo thiab lub neej nquag ntawm tus neeg sawv cev tso tawm. Tshwj xeeb tshaj yog nyob rau hauv cov neeg sawv cev pwm uas yuav tsum muaj kev huv, siab pob tshab, qhov zoo ntawm boric acid yog qhov pom tseeb.
Magnesium stearate: txawm hais tias magnnesium tseem ceeb tseem muaj cov kev cuam tshuam zoo heev, nws yuav txwv nyob rau hauv qee daim ntawv thov daim ntawv thov vim nws qhov kev ua insoluble hauv dej. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas muaj qhov kev ua kom huv thiab pob tshab, magnesium stearate kuj tsis yog qhov kev xaiv zoo tshaj plaws.
Raws li CPO tus tswv cuab ntawm NSPF, peb tus kws ua haujlwm tswj lub pas dej nrog cov kev mob khaub thuas txhua hnub, peb muaj kev kho pas dej thiab khib nyiab dej rau ntau tshaj 29 xyoos. Tiv tauj peb kom paub cov ntsiab lus thov thiab cov tshuaj tua hluav taws hauv kev ua haujlwm zoo tshaj plaws txoj kev.
