Sinopec Zhongke ua tiav pawg tsim tawm hnub ci photovoltaic qib EVA hais

Tsis ntev los no, EVA (ethylene-vinyl acetate copolymer) cog ntawm Zhongke Refining thiab Chemical Co., Ltd. tau tsim ib yam khoom tshiab ntawm hnub ci photovoltaic cov ntaub ntawv thawj zaug, uas yuav zoo txo ​​qhov kev cia siab ntawm cov khoom no ntawm kev xa khoom thiab txhawb kev hloov pauv. ntawm imports los ntawm cov khoom siv hluavtaws.

Nyob rau hauv xyoo tsis ntev los no, nrog rau high-end kev loj hlob ntawm lub domestic hnub ci photovoltaic kev lag luam, lub domestic kev thov rau EVA cov khoom, tshwj xeeb tshaj yog high-end photovoltaic cov ntaub ntawv, tau nce ho, thiab ntshuam dependence tseem nyob rau theem siab. Cov khoom siv tuaj yeem siv los ua cov ntawv ntim cov yeeb yaj kiab, cov yeeb yaj kiab uas muaj cua sov, cov yeeb yaj kiab ua liaj ua teb, cov khoom ntim khoom noj, cov duab hluav taws xob photovoltaic cell lamination zaj duab xis, lub zog siab rupture-resistant hnab, thiab lwm yam.

Cov txheej txheem tsim khoom ntawm cov khoom no tau ntsib nrog peb qhov kev sib tw loj: cov ntsiab lus vinyl acetate siab, siab yaj Performance index thiab kev ua phem heev. Thaum lub sij hawm hloov dua siab tshiab, cov kws kho mob tau mloog zoo rau cov tshuaj tiv thaiv kev tswj tsis tau, nruj me ntsis tswj cov cim tseem ceeb xws li cov tshuaj tiv thaiv siab thiab kub, nce qhov ntim ntawm cov yas acetate stepwise, thiab maj mam nce qhov ntim ntawm propylene los kho cov yaj index ntawm cov khoom thiab tsis txhob ua decomposition tshuaj.

Tsis tas li ntawd, kev tswj cov tshuaj tiv thaiv ntawm cov khoom no yog qhov nyuaj, thiab kev ua haujlwm ntawm extruder kuj tseem siab heev. Nyob rau hauv cov txheej txheem ntawm kev hloov pauv ntau lawm, cov neeg ua haujlwm sab hauv thiab sab nraud ntawm pab pawg sib koom ua ke, ua ke nrog kev ua haujlwm ntawm cov hom zoo sib xws, ib txwm ua tib zoo saib xyuas qhov tam sim no ntawm extruder thiab lub siab ntawm lub taub hau tuag, thiab kho qhov kub thiab txias. lub thoob dej, qhov ntsuas kub ntawm cov dej pellet thiab qhov ceev ntawm cov pelletizer, kom tsis txhob lo rau riam thiab ua cov khoom nplaum. Thaiv lub raj xa dej thiab vibrating npo. Kev khiav hauj lwm sab nraud yuav tsum tau ntxiv dag zog rau kev tshuaj xyuas ntawm lub vibrating npo thiab cov tsos ntawm cov khoom kom ntseeg tau tias cov nyhuv pelletizing zoo.
