Abakhiqizi bezimpawu zezimpawu nezinye izinto ezisetshenziswayoi-polymer(PTFE) ngokushesha ukuthi bagcine beshanele ingxenye enkulu yenzuzo yabo ngama-chips omshini lapho bekhiqiza izingxenye ezivela ezindongeni ezibunjwe ngokujwayelekile namashubhu.Ama-resin e-PTFE ayabiza futhi enza izingxenye ezivela ezindongeni ezibunjiwe zokucindezelwa noma amashubhu ngokuvamile agcina ekhiqiza kuphela u-10-20% wezinto ezithengwe ezingxenyeni eziqediwe.Njengoba i-PTFE, uma i-sintered, ingakwazi ukuhlehliswa futhi isetshenziswe kabusha, u-80% wezindleko ezibonakalayo ugcina kudoti.Impendulo iwukusebenzisa amasu okubumba isostatic ukukhiqiza amashubhu amancane anezindonga.
Ekuqaleni, ngenkathi izihlangu zokushisa zama-missile cones zenziwa kusukela ku-PTFE, kwakudingeka indlela yokucindezela ngokulinganayo i-PTFE powder endaweni emise okwenhlamvu yekhoni yekhala.Lokhu kwenziwa ngokubeka i-PTFE powder phezu kwepulaki ye-aluminium emise okwekhoni yekhala, bese kuvala impushana ngesinye se-elastomeric.Ipulaki, impushana kanye nesinye kwabe sekufakwa emkhunjini ocindezelayo futhi amanzi anomfutho ophezulu aphonswa ukuze kufinyelelwe ukuminyanisa kwempushana ibe yisimo esenziwe ngaphambili esilungele ukushiswa kuhhavini.
Njengonothi oseceleni othakazelisayo, njengoba amarokhethi ekhula, nezigaxa zekhala zaba zinkulu kakhulu ukuba zingene emikhunjini yokucindezela, amapulaki ambozwe esinyeni anempushana yenhlaka efakwe ngaphakathi ayevele ehliselwe olwandle ekujuleni okufanele ukuze kuzuzwe ukucindezela okufanele.
I-isostatic yesimanjeimishini yokubumbabaye basuka kude kusukela missile ekhaleni Isigaxa izinsuku.Manje basebenzisa uwoyela esikhundleni samanzi emikhunjini ye-cylindrical pressure.Imishini yokubumba ye-Isostatic ngokuvamile isebenzisa isistimu ye-hydraulic pressure feeding intensifier yangokwezifiso ukukhahlela ingcindezi ikhuphuke isuka ezingxenyeni ezivamile zesistimu ye-hydraulic ye-psi engu-3000 kuya kungcindezi ephakeme edingekayo ukuze kuzuzwe izici ezibonakalayo ezifanele ku-PTFE ebunjiwe.
Imiklamo engcono isebenzisa ama-mandrel ashintshashintshayo ukwenza iyunithi ivumelane nosayizi abaningi beshubhu, kanye nezingcezu zokugcina ze-polyurethane namafomu obubanzi obungaphandle ukuze kudluliswe umfutho we-hydraulic usuka esinyeni urethane ukuya kosayizi abahlukahlukene beshubhu.I-urethane ethambile isebenza njengoketshezi ngokwalo ukuze idlulisele umfutho we-hydraulic kunhlaka eyimpuphu ecindezelwayo.Ngokusebenzisa ama-soft end bells, ukukhala kokuphela okuvamile ngemiklamo yangaphambili kuyasuswa ukuze bonke ubude beshubhu ebunjiwe busebenziseke.
Kudingeka izilawuli ezincane ze-hydraulic, futhi iningi lezingxenye ze-hydraulic ezidingekayo zitholakala ngaphandle kweshalofu.Okuhlukile ukuqinisa, okufanele ngokuvamile kuklanywe kusukela ekuqaleni ukuze kuzuzwe umfutho odingekayo kanye nezidingo zokwakheka kwevolumu yohlelo olukhulu kangaka, oluguquguqukayo lwe-hydraulic.
