Chitarisiko chedu chakajairwa chekunamira chinopisa chakanyunguduka chinonyanya kuchena, uye zvimwe zviri pachena.Saka chii chatinofanira kuita kuti kupisa kunyungudika kunamira kujeka uye kuchena?Subang inokurudzira kuwedzera mvura shoma panguva yekugadzira.Hot melt adhesive fluorescent whitening agent.
Ethylene uye vinyl acetate ndiwo masisitimu ekutanga anopisa anonyungudusa adhesives, ayo akaiswa pasi petembiricha yepamusoro uye yakanyanya kudzvanywa, inova EVA resin.EVA resin ndicho chikamu chikuru chekugadzira inopisa inonamira inonyungudika, uye basa rekutanga rekunyungudusa rinonamira rinotemwa nechikamu uye mhando yeresin.Zvisinei, zvakakosha zvikuru kusarudza EVA yakanyunguduka chigunwe.Muduku munwe wakanyunguduka, urombo hunyoro uye simba guru.Iyo yakanyanya kunyunguduka tembiricha, kunowedzera kunyorova uye kupenya kweiyo adherend.Pane zvinopesana, kana iyo yakanyunguduka indekisi yakakura kwazvo, kunyunguduka kweglue kwakaderera, iyo fluidity yakanaka, asi simba rekubatanidza rakaderedzwa.Chisarudzo chekubatsira kwayo, zviri nani kuita chiyero che ethylene uye vinyl acetate yakakodzera.
Chekutanga, gadzira mafomula anonzwisisika ane huwandu hwakasiyana hwezvigadzirwa, wedzera iyo yakabikwa inopisa yakanyunguduka inonamira mbishi kune yekuita kettle, uye sanganisa yakaringana yefluorescent whitening agent yekunyungudutsa inonyunguduka inonamira neyakagadzirwa zvakaenzana mukugadzira, kazhinji imwe. toni yezvinhu zvakasvibirira Kuwedzera nezve 200g kunogona kuwana mhedzisiro yakanaka.
Wedzera tembiricha kuinyungudusa uye simbisai zvakanaka.Wobva watonhodza rabha yakanyungudutswa mune kettle yekupindura kune imwe tembiricha woiisa mune inomhanya extruder.Iyo extrusion speed ye extruder inogona kusarudzwa maererano nemhando dzakasiyana dzerabha.
Iyo extruder inosvina inopisa-yakanyunguduka adhesive mutangi remvura kuburikidza nedenderedzwa extrusion gomba pamusoro extrusion musoro.Iyo inopisa-yakanyunguduka inonamatira inokurumidza kuumbwa kana ikasangana nemvura inotonhorera.Chimuti cheglue chinotanga chatonhodzwa uye chakaumbwa kuburikidza netangi remvura inotonhorera yekutanga.Muchina wekudhonza wemushini wekupfapfaidza glue unopinda mutangi remvura inotonhorera rechipiri, uye sampu yeglue yakanyatsotonhorera uye yakaumbwa mutangi remvura inotonhorera yechipiri.Kumhanya kwekumhanya kwetsvimbo yeglue mutangi remvura inodzorwa neiyo extrusion kumhanya kweiyo extruder, kuitira kuti iyo traction muchina Iyo yekudhonza kumhanya inopindirana neye extrusion kumhanya kweiyo extruder.
Gadzirisa uye udzore hukama pakati pekumhanya kweextrusion, kutonhora kuseta kumhanya uye kumhanya kwekufambisa, uyezve kutsemura nekurongedza yakatonhodzwa inopisa inonyungudika inonamira muzvigadzirwa zvapera.Iko kuchena kukosha kweiyo inopisa melt adhesive mushure mekuwedzera iyofluorescent whitening agentzviri pachena kuti inovandudzwa nemapoinzi akati wandei, uye hazvisi nyore kuita yero munguva inotevera.
