Silicones, oo sidoo kale loo yaqaan polysiloxanes, waa polymers oo ay ku jiraan wax kasta oo aan shaqeynin, iskudhaf synthetic oo ka kooban unugyo siloxane ah oo soo noqnoqda, taas oo ah silsiladda atomyada silikoon ee beddelka ah iyo atamka oksijiinta, oo inta badan lagu daro kaarboon iyo/ama hydrogen.Caadi ahaan waa kuwo kulaylka u adkaysta oo u eg caag, waxaana loo isticmaalaa daboolayaasha, xabagta, saliidaha, dawooyinka, maacuunta wax lagu karsado, iyo kuleylka iyo dahaarka korontada.Qaar ka mid ah foomamka caadiga ah waxaa ka mid ah saliid silikoon, dufan silikoon, caag silikoon, resin silikoon, iyo caulk silikoon.Silikoonyadu waa saddex nooc: 1. Silikoon silsilad toosan;2. silicones wareeg ah;3. Silikoon isku xiran.
Tuubada fayodhowrka guud ahaan waxay ku lug leedahay nidaamyada codsiyada habka dawada.Ha ahaato xirmooyinka taangiyada la qaadan karo, go'doominta unugga rarka, boodayaasha CIP ama mid ka mid ah daraasiin kale oo codsiyo ah, shirarka tuubooyinka nadaafadda ayaa meel walba yaal.Waxay u baahan yihiin inay noqdaan kuwo nadiifin kara ama autoclave iyada oo aan waxyeello lahayn.Runtii waxaa jira laba walxood oo keliya oo buuxiya shuruudaha dawooyinka marka laga reebo buuxinta tilmaamaha FDA: Silikoon adag oo saafi ah iyo PTFE (polymer) siman.Midkee ayaa fiican in la isticmaalo?Runtii waxay kuxirantahay codsiga iyo natiijada aan isku dayeyno inaan gaarno:
Guryaha Silikoon Adag ee Saafi ah
Silikoonnada khafiifka ah ee khafiifka ah uma oggola gaaska ama dareeraha inay dhex maraan La yaqaan adkaysigiisa iyo awoodda uu u adkaysan karo falcelinta kiimikaad Awoodda isticmaalka deegaannada jeermis-dilaaca iyo sidoo kale awoodda u adkeysiga kulaylka ba'an iyo xajinta heerkulka (oo ay ku jirto isticmaalka cryogenic) deegaanka ayaa lagu xusay silikoon.Sababtoo ah si ballaaran ayaa loo isticmaalaa, waxay yihiin kuwo baahsan, biodegrade si diyaar ah, sida ay u kiciyaan dhoobo kala duwan.
Guryaha Tuubada PTFE
● Aad u culus (marka la barbardhigo silikoonka)
Sidaa darteed, kee baa ugu wanaagsan doorashada tuubada?In kasta oo shaqada codsiga ay khusayso halka kala duwanaanshaha kharashka u dhexeeya labadu aanu si gaar ah muhiim u ahayn.Tuubooyinka PTFE ayaa laga yaabaa inay door bidaan haddii aad gasho codsiyada ka sarreeya 100 PSI.Laakiin haddii aad u baahan tahay wax khafiif ah oo dabacsan sida kuwa boodayaasha unugyada xamuulka gaaban, silikoonku si weyn ayuu u shaqeeyaa.
PS: Nala soo xidhiidh si aad muunad bilaash ah u hesho alaabta PTFE
