Ama-silicones, aziwa nangokuthi ama-polysiloxanes, angama-polymer ahlanganisa noma iyiphi i-inert, inhlanganisela yokwenziwa eyenziwe ngamayunithi aphindaphindayo e-siloxane, okuwuchungechunge lwama-athomu e-silicon ashintshanayo nama-athomu omoya-mpilo, avame ukuhlangana nekhabhoni kanye/noma i-hydrogen.Ngokuvamile amelana nokushisa futhi afana nerabha, futhi asetshenziswa kuma-sealant, izinto zokunamathisela, okokugcoba, imithi, izinto zokupheka, kanye nokufakwa kwe-thermal kanye nogesi.Ezinye izinhlobo ezivamile zihlanganisa amafutha abicah, i-silicone grease, irabha ye-silicone, i-silicone resin, ne-silicone caulk.Ama-silicones ayizinhlobo ezintathu: 1. ama-silicone e-straight chain;2. ama-silicone e-cyclic;3. ama-silicone ahlanganisiwe.
Ipayipi lenhlanzeko ngokuvamile lihilela ezinhlelweni zezinqubo zezinqubo zemithi.Kungaba ama-hook ups ethangi aphathwayo, izihlukanisi zamaseli okulayisha, ama-CIP jumpers noma ezinye izinhlelo zokusebenza eziyishumi nambili, imihlangano yamapayipi e-sanitary ikhona yonke indawo.Kudingeka zihlanzwe ngesitimu noma zibe yi-autoclave ngaphandle kokulimala.Kukhona izinto ezimbili kuphela ezihlangabezana nezidingo zemithi ngaphandle kokuhlangabezana neziqondiso ze-FDA: abicah ahlanzekile aqinile kanye ne-PTFE (polymer) ebushelelezi.Iyiphi engcono ukuyisebenzisa?Kuya ngesicelo kanye nomphumela esizama ukuwufinyelela:
I-Pure Solid Silicone Properties
Ukukhanya ngesisindoKuguquguquka kakhulu Ama-Silicone ahlanzekile awavumeli igesi noma uketshezi ukuba ludluleKuyaziwa ngokuhlala isikhathi eside nekhono lokumelana nokushintshashintsha kwamakhemikhaliAmandla okusetshenziswa endaweni evalelwe inzalo kanye nekhono lokumelana nokushisa okudlulele nokubamba izinga lokushisa (kuhlanganise nokusetshenziswa kwe-cryogenic)Ayikho “imiphumela elimazayo emakiwe entweni ephilayo. emvelweni kuye kwaphawulwa ngama-silicones.Ngenxa yokuthi zisetshenziswa kabanzi, zigcwele, ziwohloka kalula, njengoba zicutshungulwa ubumba oluhlukahlukene.
I-PTFE Hose Properties
● Isinda kakhulu (uma iqhathaniswa ne-silicone) ● Iqinile kune-silicone (ingahle ithandeke noma ingafiseki kuye ngohlelo lokusebenza) ● I-pyrolysis ye-PTFE itholakala ku-200 °C (392 °F), futhi ifaka amagesi e-fluorocarbon ambalwa kanye ne-sublimate.
Ngakho-ke, yikuphi ukukhetha okungcono kwe-hose?Nakuba umsebenzi wesicelo ubalulekile ngenkathi umehluko wezindleko phakathi kwalokhu kokubili ungabalulekile kakhulu.Amapayipi e-PTFE cishe ayakhethwa uma ungena ezinhlelweni zokusebenza ezingaphezu kuka-100 PSI.Kodwa uma udinga into elula futhi evumelana nezimo njengaleyo ye- jumper cell cell load, i-silicone isebenza kahle.
PS: Xhumana nathi nge-PTFE imikhiqizo eqediwe isampula yamahhala
