Qhov tsim nyog thiab kev tshawb fawb tswj qhov kub ntawm cov yas zaj duab xis blower yog qhov zoo dua los ua kom lub tshuab zoo dua. Cov yas zaj duab xis tuaj yeem ua tiav lub hom phiaj zoo. Lub membrane ua los ntawm cov yas zaj duab xis tshuab yog zoo vim nws zoo thaiv, khaws cia freshness, hygroscopic anti-frost, thiab khov te. , Oxygen, roj-resistant, tuaj yeem siv dav hauv kev ntim khoom hnyav, xws li ntau yam txiv hmab txiv ntoo tshiab, khoom noj nqaij, pickles, mis nyuj tshiab, kua dej qab zib, khoom siv tshuaj thiab lwm yam. Qhov kub ntawm zaj duab xis yuav tsum muaj qhov kub thiab txias. Yog li cas qhov ntsuas kub no yuav tswj tau?
Raws li lub melting txoj kev xav ntawm yas, lub extrusion ntsia hlau ntawm lub extrusion zaj duab xis yog muab faib ua peb ntu: seem pub, seem melting, thiab nruab nrab seem. Thaum kawg ntawm ntu pub mis, thaum pib ntawm lub melting seem, raws li txoj kev xav ntawm melting, nws kub yuav tsum yog ib tug nplaum kub. Qhov kub ntawm ntau yam zaj duab xis tshuab cov nplaum nplaum yog PP: 164-175 degrees Celsius, PE: 105-135 degrees Celsius, PA: 195-210 degrees Celsius, ib puag ncig txiav txim siab cov khoom zoo.
Nyob rau hauv qhov kev txhim kho tshiab, tus qauv qub-zog thiab muaj kuab paug ntau lawm tau nyuaj rau kev tswj xyuas. Yog tias cov yeeb yaj kiab blower ua lag luam tsis tuaj yeem ua kom zoo nrog kev txhim kho kev lag luam thiab kev tsim kho tshiab, ces nws tsuas yog tuaj yeem ua tau raws li kev ua lag luam raug tshem tawm, PE zaj duab xis yog dav siv nyob rau hauv lub neej txhua hnub, thiab kev loj hlob ntawm PE. tshuab zaj duab xis kuj nthuav tawm ib daim ntawv zoo. Raws li qhov xwm txheej tshiab, kev txuag hluav taws xob ntsuab thiab kev tiv thaiv ib puag ncig tau dhau los ua txoj kev txhim kho tshiab. Nws tseem ua tsis tu ncua. PE ua npuas ncauj zaj duab xis tsim los ntawm PE raws li cov khoom siv yog cov khoom lag luam tshiab raws li qhov xwm txheej tshiab.
