Yuav ua li cas sintering lub sij hawm ntawm PTFE high-temperature ntaub yuav tswj?

I.AdjustingtheFabricTravelSpeed:TheCoreControlMethod

Kev sib raug zoo ntawm kev ceev thiab sijhawm: Sinteringtime(s) =effectiveheatingsectionlengthoftheoven(m)÷fabrictravelspeed(m/s).Forexample, iftheeffectivesectionlengthis15mandthelinespeedis5m/min,thetimeis3minutes.Productionlinesusefrequencyconvertersorservomotorstopreciselyadjustingtime

Preoritizespeedadjustment: Temperaturehashighthermalinertia.Nyob ruaj khovproduction,thetemperature should be fixed,andthelinespeed shouldserveasthemostresponsive'timedial.'Whenfine-tuning isneeded, speedadjustment should beprioritized.

II.DefiningEffectiveSinteringTimeandTemperatureZoneSettings

Use350° Castheeffectivesinteringthreshold: PTFEmeltsatapproximately327°C, butindustriallevelingrequires370–395°C.Yog li ntawd, thezoneabove350°Cisdefinedastheeffectivesinteringzone.Onlythetimethefabricspendsabovethistemperature.

Multi-zonetemperaturedistribution: Preheatingzone (100-250 ° C) - tshem tawm cov txheej txheem thiab tiv thaiv kom tsis txhob tawg; Sinteringzone (360 - 395 ° C) - ua tiav cov qib melting; High-temperaturesettingzone (380-390 ° C) -relievesinternalstress; Coolingzone(cooledbelowing)30.

Calculatingeffectiveresidencetime:Dividethetotalengthofallzonessetat≥350°Cbythelinespeed.Forexample, ifthetotalengthofsectionsabove350°Cis10mandthespeedis4m/min,theeffectivesinteringtimeis2.5minutes.

III.ProductSpecificationsDetermineTargetTimeandAdjustments

Referencesinteringtimes(at380–390°C): Lightweights(0.08–0.13mm)–30–60seconds;Standardtypes(0.18–0.25mm)–1.5–3minutes;Heavytypes(0.35mmandabove)–3–5minutesorlonger,withside”outsided”sided.

Kev txheeb xyuas thiab kev hloov kho: Insufficientsintering(lowstrength, powdershedding, micro-cracks) → txo speedtoextendtime; Over-sintering (daj, brittleness, irritatingwhitefumes) → nce speedtoshortenhigh-temperatureresidence.

Kaw-loopcontrol: Tsim kom muaj lub kaw lus kaw 'speed/temperaturesetting → qualityinspectionfeedback → kho.'Temperatureshouldberelativelyfixed, withspeedservingasthereal-timecontrolvariable.

Cov kev txwv tseem ceeb: PTFE decomposes saum toj no 415 ° C, tso tawm toxicgases; ncua sij hawm nyob rau saum toj 400 ° Cisstrictly prohibited.Extended high-temperature exposuredamagestheglassfibersizin gagent, ua rau kom txo qis hauv basefabricstrength.Afterintering, thecoolingrateinthe 300–250° Ccrystallizationzone yuav tsum tau tswj tau kom muaj kev sib haum xeeb.
