I-RTV2 isikhunta irabha ye-silicone ewuketshezi yezinhlobo ezahlukahlukene zokuhlobisa amakhandlela

incazelo emfushane:

Izinga lokushisa elisebenzayo le-silicone yesikhunta se-liquid
Izinga lokushisa elisebenzayo le-silicone yesikhunta esiwuketshezi liphakathi kuka -40 ℃ no-250 ℃

Izinga lokushisa lokubumba lemikhiqizo ye-silicone ewuketshezi inqunywa ngokusekelwe ezintweni zomkhiqizo.Ukushisa kwegumbi irabha ye-silicone ene-vulcanized ingahlukaniswa ngohlobo lwe-condensation kanye nohlobo lokwengeza ngokuya ngomshini wayo we-vulcanization;ingahlukaniswa ngezinhlobo ezimbili ngokwendlela yayo yokupakisha: izingxenye ezimbili kanye nengxenye eyodwa.Imvelo yamabhondi e-silicon-oksijeni akha iketango eliyinhloko lerabha ye-silicone inquma ukuthi irabha ye-silicone inezinzuzo ezingenazo irabha yemvelo namanye amarabha.Inebanga lokushisa elibanzi kakhulu lokusebenza (-40°C kuya ku-350°C) futhi inokumelana okuhle kakhulu nokushisa okuphezulu nokuphansi.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Indlela yokudiliza ngokushesha imikhiqizo yesikhunta se-silicone imi kanje

Ithiphu 1. Ukukhetha impahla: Zama ukukhetha izinto ezibushelelezi ukuze wenze isikhunta esiyinhloko kanye nohlaka lwesikhunta.Uhlaka lwesikhunta lungenziwa ngamabhulokhi wokwakha epulasitiki noma amabhodi e-acrylic.

Ithiphu 2. Isisetshenziswa sokukhipha isifutho: I-ejenti yokukhulula isifutho kusikhunta esiyinhloko.Ama-ejenti okukhululwa ajwayelekile asekelwe emanzini, omile, futhi asekelwe kuwoyela.Ngokuvamile, ama-ejenti okukhululwa asekelwe emanzini kanye nama-resin-based release agent asetshenziselwa ukwenza isikhunta esifana netshe elikhulisiwe kanye nokhonkolo.Sebenzisa i-ejenti yokukhululwa eyomile (ebizwa nangokuthi i-neutral), uhlobo lwe-polyurethane sebenzisa i-ejenti yokukhulula uwoyela, uma inani elincane lesikhunta liphendulwa, ungasebenzisa futhi insipho yesitsha noma amanzi anensipho esikhundleni salokho.

Ithiphu 3: Vula isikhunta ngemva kokuqina okuphelele: Njengoba inqubo yokuphulukisa ye-silicone ewuketshezi isuka ekuqineni kokuqala kuya ekuqinisweni okuphelele, abantu abaningi abazama ukujikisa isikhunta bavula isikhunta ngokushesha ngemva kokuqiniswa kokuqala.Ngalesi sikhathi, i-silicone ayiqini ngokuphelele futhi ingase iqiniswe ngokukha phezulu.Uma ungqimba lwangaphakathi lungelapheki, ukuphoqa isikhunta ukuthi sivule ngalesi sikhathi kuzophinde kubangele izinkinga ngolwelwesi lwamafinyila olulapheke ngokwengxenye.Ngakho-ke, ngokuvamile kunconywa ukuvula isikhunta ngemva kwamahora angu-12 kuya kwangu-24.Lokhu kungagwema futhi inkathazo yokuguqulwa noma ukwanda kokuncipha kwesikhunta se-silicone..

Ithiphu 4: Khetha i-silicone elungile: Uma usebenzisa i-silicone ewuketshezi ukubumba imisebenzi yezandla ye-epoxy resin ebonisa ngale, udinga ukukhetha i-silicone elungile.Uma usebenzisa i-condensation liquid silicone futhi unezinkinga zokunamathela kwesikhunta, ungafaka isikhunta se-silicone kuhhavini.Bhaka isikhunta ezingeni lokushisa elimaphakathi (80℃-90℃) amahora amabili, kuye ngosayizi wesikhunta se-silicone.Bese, linda isikhunta se-silicone ukuthi siphole bese usebenzisa i-epoxy resin ukuxazulula inkinga yokunamathela kwesikhunta.Uma usebenzisa isikhunta sesikhunta esiwuketshezi esingeziwe, inkinga yokunamathela kwesikhunta ukuthi isikhunta se-silicone noma i-master prototype ayihlanzekile ngokwanele, noma ukuthi kunenkinga ngekhwalithi ye-silicone noma i-resin.

Izizathu zokuthi kungani i-silicone yesikhunta ingaqini

Izizathu zokuthi kungani i-silicone yesikhunta ingaqini kungase kube ngenxa yamaphuzu amathathu alandelayo: 1:

Izinga lokushisa liphansi kakhulu.I-silicone ewuketshezi kuzoba nzima ukuyiqinisa ngaphansi kuka-10°C.Lesi simo ngokuvamile senzeke kakhulu ebusika.Kulokhu, ingaxazululwa ngokukhuphula izinga lokushisa ekamelweni libe ngaphezu kuka-20 ℃.

Isilinganiso se-hardener asilungile.Ngokuvamile, isilinganiso sejeli ye-silica yohlobo lwe-condensation ne-ejenti yokwelapha ngu-100:2.Uma isilinganiso se-ejenti yokwelapha esingeziwe sincane kakhulu, ngeke kubangele ukwelapha noma ubunzima ekwelapheni.Ukwengeza, i-ejenti yokwelapha enikezwa umenzi ngokuvamile iyisilinganiso sesisindo kunesilinganiso sevolumu.
Ijeli ye-silicone ne-ejenti yokwelapha ayixubene ngokugcwele ngokulinganayo.Uma ingxube inganyakaziswanga ngokulinganayo, ngokuvamile izoholela ekuqinisweni okuyingxenye kanye nokungaqini ngokwengxenye.Ngakho-ke, lapho uvuselela, qaphela i-silicone esele emakhoneni esitsheni.
