Irabha yeSilicone imathiriyeli ekrwada yeeProjekthi zokuBumba aMatye eSiko oFakelwe umfanekiso

Imathiriyeli yeRubha yeSilicone yeeProjekthi zokuBumba aMatye eSiko

inkcazelo emfutshane:

Ukulumkela:
1. Ixesha eliqhelekileyo lokusebenza le-silicone ye-condensation yimizuzu engama-30 kwaye ixesha lokunyanga liyi-2 iiyure.Inokudilizwa emva kweeyure ezisi-8 kwaye ayikwazi ukufudunyezwa.
2. Umlinganiselo we-condensation silicone curing agent engaphantsi kwe-2% uya kwandisa ixesha lokunyanga, kwaye umlinganiselo ongaphezulu kwe-3% uya kukhawuleza ukunyanga.

Indlela yokudilizwa ngokukhawuleza kweemveliso zokubumba ze-silicone ngolu hlobo lulandelayo:

Ingcebiso 1. Ukukhetha izinto eziphathekayo: Zama ukukhetha izinto ezigudileyo ukwenza i-master mold kunye nesakhelo sokubumba.Isakhelo sokubumba sinokwenziwa ngeebhloko zeplastiki zokwakha okanye iibhodi ze-acrylic.

Ingcebiso yesi-2. I-arhente yokukhulula isitshizi: I-arhente yokukhulula isitshizi kwi-master mold.Iiarhente zokukhululwa eziqhelekileyo zisekelwe emanzini, ezomileyo, kunye neoli.Ngokuqhelekileyo, i-agent-based release release agents kunye ne-resin-based release release agents zisetyenziselwa ukwenza i-molds efana nelitye elikhukhulayo kunye nekhonkrithi.Sebenzisa i-ejenti eyomileyo (ekwabizwa ngokuba yi-neutral) yokukhululwa, uhlobo lwe-polyurethane lusebenzisa i-oyile yokukhupha i-oyile, ukuba inani elincinci lokungunda liguqulwa, ungasebenzisa isepha yesitya okanye amanzi anesepha endaweni yoko.

Icebiso lesi-3: Vula isikhunta emva kokuqiniswa okupheleleyo: Ekubeni inkqubo yokunyanga ye-silicone engamanzi isuka ekuqinisweni kokuqala ukuya ekuqinisweni okupheleleyo, abantu abaninzi abazama ukuguqula ukubumba bavule ngokukhawuleza emva kokuqiniswa kokuqala.Ngeli xesha, i-silicone ayiqini ngokupheleleyo kwaye inokuqiniswa nje kuphela.Ukuba umaleko wangaphakathi awunyangeki, ukunyanzeliswa kwesikhunta ngeli xesha kuya kubangela iingxaki kwi-membrane ye-mucous ephiliswe ngokuyinxenye.Ke ngoko, kucetyiswa ngokubanzi ukuba uvule isikhunta emva kwe-12 ukuya kwiiyure ezingama-24.Oku kunokuthintela ingxaki yokuguqulwa okanye ukunyuka kwe-silicone mold.

Icebiso lesi-4: Khetha i-silicone efanelekileyo: Xa usebenzisa i-silicone engamanzi ukubumba imisebenzi yezandla ye-epoxy resin ebonakalayo, kufuneka ukhethe i-silicone efanelekileyo.Ukuba usebenzisa i-silicone yolwelo lwe-condensation kwaye unengxaki yokuncamathela ngumngundo, ungabeka umngundo we-silicone kwi-oveni.Bhaka i-mold kwiqondo lokushisa eliphakathi (80℃-90℃) iiyure ezimbini, kuxhomekeke kubukhulu be-silicone mold.Emva koko, linda ukungunda kwe-silicone ukuba kuphole kwaye emva koko usebenzise i-epoxy resin ukusombulula ingxaki yokuncamathela komngundo.Ukuba usebenzisa i abicah ulwelo additive ngungundo, ingxaki ngundo ukuncamathela mhlawumbi ukuba ukungunda abicah okanye master prototype ayicocekanga ngokwaneleyo, okanye kukho ingxaki umgangatho abicah okanye resin.

Ngaphambili: Ubushushu obuphezulu bokumelana ne-electronic potting irabha ye-silicone edibeneyo

Okulandelayo: Irabha ethambileyo ye-silicone i-viscosity ephantsi ye-viscosity abicah kwaye akukho mfuneko yokufunxa ibakala lokutya lokufunxa irabha elulwelo lwe-silicone yokwenza umngundo we-DIY
