(1), sib xyaw cov ntaub ntawv, PVC yeeb nkab yog PVC muaj kev ruaj ntseg tshuaj, yas rau plawv, tshuaj antioxidant thiab lwm yam khoom siv, raws li sib qhia, siv tshuab txuas mus rau hauv high speed ceev tshuab, txias tov tshuab khoom txo mus rau 40-50 degrees; Nws tuaj yeem raug ntxiv rau qhov qhwv ntawm extruder.
(2) Qee extruders: lub tshuab muaj nruab nrog ntau qhov khoom noj khoom haus, yog li cov nyiaj rho tawm yuav muab sib piv nrog cov nyiaj pub mis kom ua rau cov khoom sib npaug ntawm cov khoom tiav. Vim tias cov khoom siv ntawm cov hlua khi tsim, lub sijhawm them cov kab loj, PVC lub raj xaib ntawm cov khoom siv thiab cov khoom sib txig sib txig, zoo rau cov khoom yas, ntsuas qhov ntawm lub hau ntswj me me, cheeb tsam thiab lub tsho tus nqi ntawm yaj, tuaj yeem ua rau lub pas dej sov nyob hauv qis dua. Thaum cov ntsia hlau ciam hauv lub tog raj kheej, lub PVC yog plhaws rau lub taub hau, thiab tom qab ntawd nws nce mus txog compaction, melting thiab tov. Thiab xaus lub hom phiaj ntawm cov pa thiab lub cev qhuav dej. Cov khoom noj khoom siv thiab cov khoom siv ntsia hlau tsav xaiv cov kev tswj kom hloov ceev ceev, tuaj yeem ua kom tswj tau qhov sib npaug.
(3) lub taub hau tuag tawg yog qee qhov: PVC nrog compacted, melting thiab mixing, thiab cov khoom siv hauv qab no yog ntsib cov tuag lub taub hau nrog lub hau nqus, thiab lub plab tuag tuag yog kaw qhov ntawm cov yeeb nkab sib sau.
(4), lub tshuab nqus tsev rau lub tshuab nqus tsev, lub cav nqus dej, cov kav xa dej, PVC yeeb nkab nqus dej rau qhov chaw thiab txias dej tank ntawm lub tshuab nqus tsev thiab dej ncig, tsis muaj steel hlau casing, txau cov dej txias, mobile devices thiab tswj ua ntej thiab tom qab lub tshuab nqus tsev calibrating mounted ntawm lub tank, concave thiab convex hloov ntaus ntawv manually.
(5) Tsav tsheb ciav hlau siv los mus ua kom tiav thiab pib mus ua kom lub raj txias thiab tawv tawv los ntawm lub qhov ntswg, thiab kev tswj xyuas qhov kev txwv ntau zaus.
(6), muab khawm khawm: raws li qhov yuav tsum tau ntev ntev los ntawm kev hloov mus txawv tebchaws, nres kev qhib, thiab ncua lub dav hlau, cov dej siv, txiav ib lub teeb nruam nrog kev hloov ntev li qhov kev qhia, xaus kev ua, ntawm kev txiav thiab cov yeeb nkab ua haujlwm hauv kev sib tw, txiav cov txheej txheem uas tau tsav los ntawm hluav taws xob thiab pneumatic, kawg txiav khau raj nrog cov khoom siv plua av, PVC yeeb nkab yuav hlais tawm ntawm cov kab tawm hauv lub sijhawm, thiab thim rov qab.
(7), tig khoom siv los ntawm lub tog raj kheej los ntawm kev tswj pneumatic, cov khoom siv ib qho kev txwv ntaus ntawv, tom qab muab cov khoom siv txiav tawm thaum sawing cov kav hlau, cov yeeb nkab txuas ntxiv mus, tom qab lub sijhawm ncua, lub tog raj kheej rau homework, . Tom qab tso tawm, nws yuav pib dua rau ob peb feeb thiab tos rau tom ntej mus los.
