“Blown film machine technology” additive: anti-adhesive, antioxidant, antistatic agent

1.2.1 anti-adhesive     The action of anti-adhesive is to prevent high molecular materials from sticking sticky. The blown film process is more likely to generate surface adhesion compared to other processes because the membrane bubbles are pressed against the first traction roller. The anti-adhesive can separate the two films. Celite is a common anti-adhesive material. 1.2.2 antioxidant Antioxidants can inhibit molecular decomposition of the polymer. The polymer chain is easily broken into a segment in an aerobic environment, especially when high temperature extrusion is extruded. Degraded polymers usually discolor and reduce product mechanical properties. Crosslinking (gel) will also be generated during oxidation. Many raw materials themselves contain antioxidants even without adding antioxidants. This ensures thermal stability in polymer processing. The action mechanism of antioxidants is to capture it before the free radical complex polymer segment produced by the oxidation reaction. Antioxidants are mainly divided into two types of phenolic and amines. 1.2.3 antistatic agent Anti-static agents are used to eliminate the electrostatic surface of the polymer. Many high molecules will accumulate electrons during processing, including the process of guiding the film through the guide roller. This phenomenon is particularly obvious when humidity is low. The mechanism of antistatic agents

Xakamaynta Heerkulka Mashiinka Afuuraya Filimka

2.1.6.1 Xakamaynta Heerkulka Tiknoolajiyadda xakamaynta heerkulka hadda waxay xakamayn kartaa isbeddelka heerkulka aag kasta oo kuleyl ah within 1 ° C. Si kastaba ha noqotee, isbedbedelka heerkulka ayaa ka sarreeya noocyo cayiman, oo saameeya isbeddellada wax soo saarka. Sidaa darteed, xakamaynta heerkulka adag waa mid aad u muhiim ah. Nidaamyo isdaba-marin ah ayaa caadi ahaan leh dhowr aagag lagu xakameeyo heerkulka. Aagga xakamaynta heerkulka waxay kuxirantahay dhererka kaydadka, qaabka iyo dhererka adabtarada iyo cabbirka iyo qaabka caaryada. Waxaa jira seddex aag xakamaynta heerkulka, waxaana jira in kabadan darsin. Aagga xakamaynta heerkulka wuxuu ka kooban yahay afarta qaybood ee soo socda: Xakameynta heerkulka, dareeraha heerkulka, kululeeyaha, unugga qaboojinta. Caadi ahaan aagga kuleylka ee kaydadka ayaa u baahan unug qaboojiye ah. Xaraarada heerkulka waa mikroroscessor. Shaqadeeda ugu weyni waa in la akhriyo heerkulka dhabta ah ee qaybta wax soosaarka heerkulbeegga, la barbardhig heerkulka la dejiyey, ka dibna la soo saaro kuleylka amarka koontaroolka ama hawlgalka cutubka qaboojinta. Xakamaynta heerkulka ayaa xakamayn kara kululeeyaha si uu u furo ama u xiro, u xakameeyo badhanka qaybta qaboojinta, ama ficillada. Wareeg ficilkani si joogto ah ayuu ugu celcelinayaa si loo hubiyo in heerkulka dhabta ahi la jaan qaadayo setka
