Analiz de pwosesis pwodiksyon an nan fib flanm dife-rezistan Polyester diskontinu

Kòm yon enpòtan materyèl twal fonksyonèl anvan tout koreksyon, flanm dife-rezistan Polyester diskontin

Preparasyon materyèl anvan tout koreksyon ak modifikasyon

Pwodiksyon de flanm dife-rezistan Polyester fib diskontinu kòmanse ak pretrateman nan Polyester bato (PET) . yo nan lòd yo bay flanm dife a flanm dife, flanm dife rezistan yo dwe ajoute pandan etap yo polimerizasyon oswa anvan yo te gen yon ti boutèy ki gen ladan yo ki gen koulè pal, ki gen pou wè ak fazin, ki gen pou wè ak fazin, ki gen baz-yo, ki gen pou wè ak fazin, ki te gen yon moun ki te gen yon moun ki te gen yon moun ki gen flanm dife ki te gen anpil dlo, ki te gen yon moun ki te gen. Avèk Polyester pa melanje oswa copolymerization {{5}

Fonn k ap vire

The dried modified polyester chips enter the screw extruder and melt into a uniform melt at high temperature (about 280-290℃). After the melt is precisely controlled by the metering pump, it enters the spinning assembly and is extruded through the spinneret to form a fine stream. The number of holes and diameter of the spinneret directly affect the Fini ak inifòmite nan fib la, ak rafineman an filaman sèl se nòmalman 1.5-5.0 denier .

Refwadisman ak lwil oliv

The extruded melt stream is quickly solidified into nascent fibers in the side-blowing or ring-blowing cooling device. The cooling air temperature is controlled at 15-25℃, and the wind speed is adjusted to ensure uniform fiber structure. Subsequently, the fiber is oiled by the oil tanker to reduce friction, improve bundling and subsequent processing Pèfòmans .

Desen ak likidasyon

Fib ki fèt la antre nan pwosesis desen an nan disk la fil gid, ak milti-etap desen (total desen miltip 3-4 fwa) anjeneral yo itilize amelyore oryantasyon an ak fòs nan fib la . fib la trase ki te fòme nan yon gato swa pa winder a pou prepare yo pou pwosesis la koupe {3 {3

Koupe ak anbalaj

Gato a swa antre nan machin nan koupe epi li se koupe an fib kout nan 38-102 mm nan longè dapre demann {{1}
