Vim li cas cov koob tshuaj ntawm PVC foaming regulator me me thiab cov nyhuv loj?

Tus tswj kev ua npuas dej PVC muaj qhov hnyav molecular siab thiab tuaj yeem txhim kho lub zog yaj ntawm PVC. Nws tuaj yeem encapsulate cov pa roj ua npuas dej, tsim cov qauv honeycomb sib xws, thiab tiv thaiv cov pa roj kom tsis txhob khiav tawm. Tus tswj kev ua npuas dej PVC yog "kev lag luam monosodium glutamate", uas siv me me tab sis nws cov nyhuv tsis tuaj yeem kwv yees tau. Kev ua tau zoo thiab zoo ntawm cov khoom PVC muaj feem cuam tshuam ncaj qha rau nws. Tom qab ntawd, nws tau pom hauv kev ua haujlwm uas ntau zaus, suav nrog cov neeg sab hauv kev lag luam, muaj kev nkag siab ntau dua lossis tsawg dua txog kev faib tawm thiab kev ua haujlwm ntawm ACR.

Feem ntau, cov khoom siv ua PVC ACR tuaj yeem muab faib ua peb pawg:

1. Txhawb kev ua cov khoom siv pab ua kom yas: Hom no siv dav hauv cov khoom PVC tawv, feem ntau yog txhawb kev ua kom yas, txhim kho cov khoom rheological yaj, txhim kho kev sib kis ntawm lwm yam khoom pab, thiab txhim kho qhov zoo ntawm cov khoom. Siv rau feem ntau cov khoom PVC xws li cov ntaub ntawv, cov kav dej, cov phaj (coils), thiab lwm yam.

2. Tus tswj ua npuas ncauj: PVC ua npuas ncauj tswj, vim nws qhov hnyav molecular siab, tuaj yeem txhim kho lub zog yaj ntawm PVC cov ntaub ntawv, zoo encapsulate foaming roj, tsim cov qauv honeycomb sib xws, thiab tiv thaiv cov roj tawm. Tib lub sijhawm, PVC ua npuas ncauj tswj kuj tseem muaj txiaj ntsig zoo rau kev sib kis ntawm lwm cov khoom ntxiv, suav nrog cov neeg sawv cev ua npuas ncauj, los txhim kho qhov zoo ntawm cov khoom thiab txhim kho qhov ci ntsa iab. Nws yog qhov tsim nyog rau cov laug cam ua npuas ncauj, cov pas nrig ua npuas ncauj, cov kav dej ua npuas ncauj, cov ntaub ntawv ua npuas ncauj, cov yas ntoo ua npuas ncauj, thiab lwm yam.

3. Cov khoom siv ua cov roj nplua nyeem sab nraud: Nws muaj cov khoom zoo ib yam li cov roj hmab oxidized polyethylene, tab sis nws txawv ntawm PVC vim nws muaj kev sib raug zoo. Nws kuj tseem tuaj yeem ua rau kev ua haujlwm yas ntau ntxiv rau qee qhov, txhim kho cov khoom rheological yaj, thiab tswj kev nthuav dav thaum lub sijhawm extrusion yam tsis hloov pauv kev ua haujlwm kub. Nws tiv thaiv cov teebmeem haze los ntawm cov roj nplua nyeem hauv cov khoom pob tshab. Haum rau cov mis lossis cov khoom siv nrog cov kev xav tau ua tiav siab, tshwj xeeb tshaj yog cov ntawv pob tshab, cov ntaub ntawv ua npuas ncauj, cov laug cam ua npuas ncauj, thiab cov yas ntoo ua npuas ncauj.

4. Tshwj xeeb tshaj yog hais txog thev naus laus zis thiab cov khoom lag luam, thaum lub sijhawm ua cov txheej txheem dov, qhov elasticity ntawm cov yaj tuaj yeem txhim kho, ua rau cov khoom seem dov du ntawm ob lub rollers; Hauv cov yeeb nkab extrusion, qhov zoo li pom tseeb tuaj yeem txhim kho, qhov tshwm sim ntawm "daim tawv nqaij ntses" tuaj yeem tshem tawm, thiab qhov nrawm extrusion tuaj yeem nce ntxiv; Kev extrusion pob tshab tuaj yeem txo qhov ntau ntawm "ntses qhov muag" hauv cov khoom; Los ntawm kev nce qhov elasticity ntawm cov yaj hauv kev txhaj tshuaj molding, qhov ntim txhaj tshuaj txo qis, qhov tshwm sim ntawm "kab dawb" txo qis, qhov ci ntsa iab ntawm qhov chaw tau zoo dua, thiab lub zog vuam tau zoo dua. Yog tias ntxiv cov khoom siv roj nplua nyeem, qhov ua tau zoo ntawm kev tshem tawm zaj duab xis tuaj yeem txhim kho, lub voj voog txhaj tshuaj tuaj yeem ua kom nrawm dua, thiab cov txiaj ntsig tuaj yeem nce ntxiv kom tiv thaiv qhov tshwm sim "tej zaum" los ntawm kev swb sab nraud thiab nag lossis daus; Tshuab molding tuaj yeem txhim kho plasticization, txo qhov tshwm sim ntawm fisheye, txhim kho elasticity yaj, thiab ua rau cov tuab molding sib xws dua.
