High Temperature tepi inoreva matepi anonamira ayo anoiswa kune yakanyanya tembiricha yekushanda nharaunda.Nechinhu chikuru chekubvisa pasina zvakasara, matepi ekupisa anonyanya kushandiswa se masking uye kudzivirira basa panguva yePowder coating, Plating, circuit board printing, wave soldering masking uye SMT mounting.Inogona kuiswa kune akasiyana siyana eindasitiri application, senge Electronic indasitiri, Automotive indasitiri, Aerospace indasitiri, nezvimwe.
Pano tinoda kurongedza matepi epamusoro sepazasi:
Kutanga, tembiricha yepamusoro inogona kukamurwa zvichienderana nemafirimu akasiyana anotakura.
Polyimide tepi,Yakatumidzwawo seKapton kana Goridhe Finger, inova ndiyo inonyanya kudhura inodzivirira kupisa zvinhu pamusika neiyo pfupi inoshandisa yakakwirira tembiricha kuramba kuita 350 ℃.Iwo General ukobvu hweKapton mafirimu 12.5um, 25um, 35um, 50um, 75um, 100um uye 125um, uye fekitori yedu inogonawo kugadzirisa mamwe makobvu akakosha se 150um, 200um kana 225um sekukumbira kwemutengi.Amber uye Nhema ruvara ndiwo maviri anonyanya kuzivikanwa ruvara, uye dema ruvara runogonawo kugadzirwa seyakajeka kana matte kupera.Mamwe mavara seGreen, Red kana Transparent anogona zvakare kugadziridzwa neimwe MOQ uye yakakwira mutengo.
Polyester zvakare yakapfupikiswa sePET (Iro zita rekemikari inonzi polyethylene terephthalate, inonziwotepi yeMYLAR)Tembiricha yaro yekunyunguduka i240 ℃, uye tembiricha yepamusoro inoshanda i230 ℃, nepo tembiricha yekushanda iri mukati me180 ℃.PET Firimu maficha ane yakakwira transmittance uye yakachipa mutengo, iyo isingango shandiswe setepi yepamusoro yekupikisa tepiasiwo seMylar insulation tepikanaPET inodzivirira firimu.Mazhinji emafirimu ePET ane ruvara rwakajeka, kunze kwerumwe ruvara seAmber color, Red, Blue uye Green color.
- 3. Girazi Mucheka Mutakuri
Girazi jira rakagadzirwa negirazi faibha uye rakarukwa sejira, uye ukobvu hwese hunosvika 130um muruvara ruchena.Girazi jira rine simba rakasimba rekusimba uye kubvarura kuramba iro rinogona kushandiswa sekuputira kana kugadzirisa kune transformer, Mota, lithium bhatiri kana kunyange mine midziyo yekugadzirisa.
Girazi faibha jira rakagadzirwa neTeflon rakarapwa uye rakaputirwa nesilicone adhesive mushure mekurapa nanochemical.Iyo ine anti-stick, yakakwirira tembiricha uye makemikari kuramba maficha, ayo anopa anogara akasimba mhinduro pane yekurongedza uye kupisa yekuisa chisimbiso michina.Ukobvu hwakazara hweTeflon girazi jira ndeye 80um uye 130um, imwe yakakosha ukobvu se50um, 150um kana 250um inogonawo kugadziridzwa sekukumbira kwevatengi.
PTFE Firimu rinosanganisira kumisa PTFE resin nekuumba, kunyura, kutonhora kuve isina chinhu.Iyo ine yakanakisa dielectric zvivakwa, kuchembera-kupokana uye corrosion kuramba maficha ayo anowanzo shandiswa pakuisa chisimbiso cheshinda, Pipe doping, plumbers uye kuputira.Kune matatu mavara ezvisarudzo, ayo machena, mashava uye matema.
Chechipiri, matepi ekushisa akakwirira anogona kugoverwa mumhando dzakasiyana-siyana sepazasi maererano nemhando dzakasiyana-siyana.
- 1. Silicone adhesive
Silicone glue ndiyo yakanakisa kupisa kupisa kumanikidza inonamira inonamira.Inogona kuramba tembiricha refu kusvika 260 ℃ uye pfupi tembiricha kusvika 300 ℃.Kune maviri masisitimu makuru esilicone glue inova BPO catalytic system uye platinamu catalytic system.BPO sisitimu yakachipa uye ine zvirinani kupisa kupisa, asi inoshatisa mamorekuru madiki esilicon dioxide, izvo zvinokanganisa kuchena kwechigadzirwa.Iyo platinum catalyst system ine kushomeka kwekushisa, asi kuchena kuri nani, kunowanzo shandiswa kugadzira silicone inodzivirira firimu zvigadzirwa.
- 2. Acrylic adhesive
Acrylic glue ine huwandu hwakawanda hweviscosity hutsanana hwakanaka asi husina kunaka hwekupisa.Iyo viscosity inogona kubva pa1 gramu yefirimu inodzivirira kusvika ku3000gram yeVHB series tepi.Kazhinji, iyo yakakwirira ye viscosity, iyo yakanyanya kupisa kupisa.Iyo tembiricha yekuchinjisa girazi ye acrylic adhesive ingangoita 200 madhigirii, chimiro che acrylic adhesive pamusoro pe200 madhigirii chachinja, uye viscosity yakadzikira.Mushure mekupeta kwapera, inoda kuporeswa uye kukura pa40 ° C kwemaawa makumi mana nemasere.Nguva yakarapwa uye yakakura yakasiyana muzhizha nechando, mazuva 3-4 muzhizha uye anenge 1 vhiki muchando.
Kudzika kwekushisa kwekudzivirira ndiko kukanganisa kwe acrylic adhesive type.Nekudaro, fekitori yeglue yakaita tsvakiridzo yakawanda kugadzirisa guruu.Parizvino, yakagadzira kupikisa kwekushisa kwe250 degrees uye viscosity ye7-8N acrylic adhesive yakakwirira.tepi tembiricha.
Chechitatu, maererano neyakasiyana dhizaini chimiro, tembiricha yepamusoro inogona kukamurwa sepazasi
