Yuav ua li cas khiav EPS ua ntej- tshuab nthuav dav?

Yuav ua li cas khiav EPS ua ntej -expanding tshuab? Hauv qab no, EPS ua ntej- cov chaw tsim khoom siv lub tshuab nthuav dav yuav qhia nws cov ntsiab lus tseem ceeb thiab kev ceev faj.

 

Qhib lub qhov rooj sab ntawm lub tshuab ua ntej- nthuav dav: Tshawb xyuas cov npuas dej lossis lwm cov khib nyiab hauv lub tshuab, thiab tshawb xyuas cov npuas dej ntawm qhov ntsuas kub ntsuas. Tom qab ntawd ceev cov qhov rooj ntawm qhov rooj. Kho lub qhov hluav taws xob qhov siab mus rau qhov siab xav tau thiab xyuas seb cov kav dej tso tawm tsis muaj kev cuam tshuam.

 

Xyuas tag nrho cov chav siab; Lub siab yuav tsum tsis txhob qis dua 3.5 kg / cm³. Nyob rau tib lub sijhawm, xyuas seb cov cua compressed ntawm lub kiv cua yog qis dua 4.5 kg / cm³.

 

Pib lub tshuab ua ntej -expanding tshuab: stirring lub cev muaj zog, lub tshuab nqus tsev vacuum, feed fan, vulcanizing txaj tshuab, thiab feed motor.

 

Qhib lub qhov cub inlet thiab qhov hluav taws xob li qub kom preheat lub preheater. Feem ntau, lub preheating kub yuav tsum ncav cuag li 80 degree. Tom qab kho qhov ceev ceev, kho qhov ceev ceev, chav loj, qhov hluav taws xob qhov siab, thiab compressed cua kom tsawg. Based on the bulk density, shrinkage rate, elasticity, and roundness of the bubble particles, stabilize the operation process as quickly as possible to achieve the specified bulk density.

 

Feem ntau, qhov ntsuas kub rau ib lub voj voog yuav tsum tau tswj ntawm 90 ~ 95 degree. Meanwhile, tus qauv thiab hom ntawm lub tshuab propulsion, cov khoom stacking ceev yuav tsum tau, chav zoo, thiab cov pa system tej yam kev mob yuav tsum tau txiav txim siab nyob rau hauv ua ke nrog rau cov teeb meem ntawm txhua lub chaw tsim tshuaj paus. Txawm li cas los xij, feem ntau nws tsis pom zoo kom ua ntej - nthuav dav ntawm qhov kub thiab txias heev lossis nrog qis qis ua ntej - nthuav dav. Nws tau pom zoo tias cov neeg siv khoom tswj hwm tus nqi ntawm cov khoom siv zoo tib yam ntawm 92-95℃thiab 13-16 g/L, nplaim taws-cov ntaub ntawv retardant ntawm 12-18 g/L, ceev- nthuav cov ntaub ntawv ntawm 15-17 g / L ntawm 12 g / L, thiab cov khoom siv sab hauv siab, zoo ntawm nthuav polystyrene khoom. Txhawm rau kho cov kev ua haujlwm tam sim ntawd, thaum lub sijhawm ua ntej nthuav dav, cov qauv yuav tsum tau nquag coj los ntawm lub pre-expander rau qhov hnyav los soj ntsuam qhov ntom ntom ntawm cov khoom ua npuas ncauj.
