Ib, Lub luag haujlwm ntawm PVC foaming regulator
Hauv cov txheej txheem tsim cov khoom ua npuas ncauj PVC, cov khoom tswj hwm ua npuas ncauj PVC ua lub luag haujlwm tseem ceeb. Nws cov haujlwm tseem ceeb tau pom tseeb hauv cov hauv qab no:
1. Txhim kho lub zog yaj: Cov khoom hloov pauv ua npuas dej PVC tuaj yeem ua rau lub zog ntawm PVC yaj zoo dua, ua rau nws muaj txiaj ntsig zoo dua hauv kev ntim cov pa roj thiab tiv thaiv cov pa roj tawm thiab cov cell tawg. Lub luag haujlwm no yog qhov tseem ceeb rau kev tswj hwm qhov ruaj khov ntawm cov duab cell thaum lub sijhawm ua npuas dej, uas pab kom tau txais cov qauv ua npuas dej sib xws dua.
2. Ua kom cov qauv ntawm lub cell zoo dua: Los ntawm kev kho qhov viscoelasticity ntawm PVC yaj thiab foaming regulator, xyuas kom meej tias cov cell tswj tau qhov ruaj khov thaum lub sijhawm loj hlob, zam kev tawg vim yog kev sib txuas ntawm cov cell sib ze lossis tsis txaus lub zog yaj. Cov qauv ntawm lub cell zoo dua ua rau kev faib tawm kev ntxhov siab sab hauv ntawm lub foam board sib xws dua thaum raug rau cov yam ntxwv sab nraud, yog li txhim kho qhov ruaj khov ntawm qhov ntev.
3. Txhawb cov txheej txheem yas: Cov tshuaj tswj ua npuas ncauj tuaj yeem txhawb kev yas ntawm PVC resin, ua rau PVC yas zoo nkauj dua, yog li txhim kho qhov ci ntsa iab thiab cov khoom zoo ntawm cov khoom.
Ob, Cov tshuaj thiab cov yam cuam tshuam ntawm PVC foaming regulator
Qhov ntau npaum li cas ntawm PVC foaming regulator sib txawv nyob ntawm cov khoom ntawm ntau lub tuam txhab tsim khoom, cov khoom siv siv, cov xwm txheej ntawm cov txheej txheem, thiab cov khoom xav tau tshwj xeeb. Feem ntau, nws cov ntau npaum li cas yog ntawm 1% thiab 5%. Qhov ntau no yog raws li kev paub dhau los ntawm kev tsim khoom tiag tiag thiab ntau cov ntaub ntawv sim, thiab tuaj yeem siv ua qhov siv los ua piv txwv.
Txawm li cas los xij, nws tsim nyog sau tseg tias qhov ntau ntawm cov tshuaj tswj kev ua npuas ncauj uas siv tsis tas yuav zoo dua. Cov tshuaj tswj kev ua npuas ncauj ntau dhau yuav ua rau muaj kev ua npuas ncauj ntau dhau, ua rau muaj qhov ntau thiab tsawg ntawm cov qhov hws tsis tuaj yeem tswj tau, yog li ntawd cuam tshuam rau qhov zoo ntawm cov khoom. Ntawm qhov tsis sib xws, kev siv tshuaj tsis txaus yuav ua rau muaj kev ua npuas ncauj tsis txaus, ua rau muaj qhov tsis zoo ntau ntxiv, thiab tseem ua rau cov khoom tsis zoo.
Yog li ntawd, thaum txiav txim siab qhov ntau npaum li cas ntawm PVC foaming regulator, ntau yam xws li lub hom phiaj khoom, cov khoom siv muaj peev xwm, thiab cov txheej txheem yuav tsum tau txiav txim siab kom pom qhov sib npaug zoo tshaj plaws.
3, Txoj cai ua haujlwm ntawm PVC foaming regulator
PVC foaming regulator yog ib yam khoom siv ua acrylic, nrog rau qhov hnyav molecular siab dua li cov khoom siv ua haujlwm dav dav. Thaum lub sijhawm ua haujlwm, cov saw hlau ntev ntawm cov foaming regulator yuav qhwv thiab lo rau cov saw hlau molecular ntawm PVC, tsim ib qho qauv network. Cov qauv no tsis yog tsuas yog ua kom lub zog yaj ntawm PVC zoo dua, tab sis kuj txhim kho cov khoom siv lub cev xws li elasticity thiab elongation ntawm yaj, yog li ua rau cov npuas encapsulation thiab tiv thaiv lawv coalescence lossis tawg.
Tsis tas li ntawd xwb, cov tshuaj tswj kev ua npuas dej kuj tseem tuaj yeem tswj qhov kev ntws ntawm cov saw hlau molecular PVC, txo qhov kev sib txhuam ntawm cov saw hlau molecular, thiab ua rau PVC resin ntws zoo dua thaum lub sijhawm ua tiav. Qhov no pab kom tau txais cov khoom ua npuas dej uas muaj qhov zoo nkauj.
Hauv kev xaus lus, cov khoom tswj hwm PVC ua npuas ncauj ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom ua npuas ncauj PVC los ntawm lawv txoj hauv kev ua haujlwm tshwj xeeb. Nws tsis tsuas yog txhim kho qhov zoo thiab kev ua tau zoo ntawm cov khoom, tab sis kuj tseem ua kom zoo dua cov txheej txheem tsim khoom thiab ua kom muaj txiaj ntsig zoo dua. Yog li ntawd, nws yog qhov tseem ceeb heev uas yuav tsum xaiv cov neeg sawv cev ua npuas ncauj tsim nyog hauv cov txheej txheem tsim khoom ntawm cov khoom ua npuas ncauj PVC.
