Cajaladda PTFE fiberglass waxay u baahan tahay saddex shahaado oo badbaado oo muhiim ah: UL (badbaadada korantada iyo ololka), FDA (u hoggaansanaanta xidhiidhka cuntada), iyo ISO 9001:2015 (maaraynta tayada). Cajalado shahaadeysan ayaa bixiya waxqabad joogto ah, nolol adeeg oo dheer, iyo wadarta qiimaha lahaanshaha oo hooseya in kasta oo qiimaha hore uu sareeyo. Had iyo jeer si toos ah uga xaqiiji shahaadaha hay'adaha soo saaray.

Cajalad heerkul sare leh oo PTFE ah ayaa loo isticmaalaa saddex heer oo kala duwan oo codsi caafimaad ah: ilaalinta qalabka jeermiska (trays autoclave, baakadaha kulaylka), daawaynta dusha sare ee qalabka (daahan-jilicsan, dahaarka korantada), iyo aaladaha la rakibi karo (talaalada xididdada dhiigga, tolidda). Biocompatibility waxaa lagu xaqiijiyay ISO 10993, iyo FDA 21 CFR 177.1550 waxay dejisaa badbaadada alaabta aasaasiga ah.

PTFE cajalad heerkul sare ah ayaa iska caabin xun u leh shucaaca ionizing. Kaliya 1 kGy soo-gaadhista gamma, awoodda xajintu waxay hoos ugu dhacdaa ~ 25% ee asalka ah. Waxay ku habboon tahay oo keliya deegaannada qiyaasta-hooseeya (cunto/ jeermis-dilid caafimaad <10kGy). Warshadaha nukliyeerka ama dayax-gacmeedka, isticmaal polyimide ama PEEK beddelkeeda.

Cajalado heerkul sare oo PTFE ah oo ku hoos jira dhex-gelinta muddada-dheer, substrate-ka PTFE wuxuu ahaanayaa mid kiimiko ahaan aan firfircoonayn, laakiin lakabka koollada ayaa ah barta daciifka ah. Biyuhu waxay daciifiyaan silikoon PSA; Biyaha cusbadu waxay dardargeliyaan daxalka. Kiimikooyinka gardarada leh, fluorosilicone ama perfluoropolyether xabag-ama cajalad PTFE-la'aan ah ayaa loo baahan yahay. Luminta xoogga diirka ilaa 40% ka dib 48 saacadood oo biyo ah.

Cajalad heerkul sare oo PTFE ah oo loo isticmaalo codsiyada xidhiidhka cuntada waa in ay ku sugnaataa xadka heerkulka la cayimay: ≤260°C si joogto ah loo isticmaalo, ≤300°C meelaha ugu sarreeya (daqiiqado), oo aan waligii ka sarrayn 327°C (dalool). Xeerarka FDA iyo EU ma sheegaan wakhtiga caalamiga ah - muddada xidhiidhka badbaadada leh waxay ku xidhan tahay heerkulka oo waa in lagu xaqiijiyaa tijaabooyinka socdaalka ee u ekaysiinaya xaaladaha dhabta ah.

Doorashada saxda ah ee PTFE-ku-kulul sare ee sariirta kulul ee daabacaadda 3D waxay u baahan tahay in diiradda la saaro afar tilmaame oo muhiim ah: caabbinta heerkulka (ilaa 260 ° C +), xuubka fiberglass-xoojiyey (0.18mm fiican), taageere silikoon oo leh dusha sare ee aan dhejin, iyo ballac / dulqaad habboon. Hagahan waxa uu kaa caawinayaa in aad iska ilaaliso is-daba-marin, hadhaaga, iyo guuldarrada daabacaadda.

Doorashada warqadda la sii daayo ama substrate filimada iyo wakiilka sii deynta ayaa si toos ah u saameeya xasilloonida kaydinta iyo diirinta cajaladda heerkulka sare ee PTFE. Maqaalkani waxa uu isbarbar dhigayaa PET vs. kraft substrates warqadaha iyo silikoon vs. wakiilada sii daayo fluorinated, ku talinaynaa isku darka ugu fiican ee eber-hadha diirinta iyo kalsoonida muddada-dheer.
