Injection silicone rubber foaming ngu ai gaw, liquid silicone rubber (LSR) hpe foaming agent hte kayau kaya galaw ai ladat langai rai nna, katsi ai hte n-gun dat ngut ai hpang, mold langai hta porous jat bang da ai arung arai hpe kalang ta hpaw ya ai.
Ra arung arai ni hpe hkyen lajang ai lam hte kayau kaya ai lam ni:
Liquid silicone rubber (LSR) hpe base rubber hku nna lang ai, dai gaw law malawng gaw lahkawng lahkawng-component (A/B daw) rai nga ai. Liquisely silicone gel hpe chemical foaming agents ni (compounds ni gaw, nbung katsi ai shara ni hta gas shapraw na matu n-gun yawm mat ai) hte ra ai nsam pang ni hte kaga additives ni hpe hkrak hkrak kayau bang u. Mixing galaw ai lam gaw langai sha re ai hte gas hpe tau hkrau n shapraw ra ai.
Injection molding:
Dai hka htung-}mixed ntsin hpe metering pump hku nna bang ai n-gun rawng ai jak a barrel kata de sa dat ai. Dai jak gaw, ntsin htum ai arai langai ngai hpe pre{2}}} n-gun rawng ai hka htung kata de bang ya ai. Ndai aten hta, mold temperature hpe foaming agent a decomposition temperature hta npu de hkang nna, mold filling galaw ai aten hta n-gun n rawng ai foaming hpe pat shingdang na matu galaw ai.
Foaming hte vulcanization:
Mold cavity hpe hpring hkra galaw ngut ai hpang, n-gun n-gun gaw, foaming agent a n-gun n-gun (130℃hte 180℃lapran) hta grau lawan ai hku rawt jat wa ai, dai foaming agent gaw, silica gel matrix kata na n-gun n rawng ai cell kaji ni law law hpe hpaw hpang wa ai, nbung katsi ai, n-gun dat ni hpe n-gun dat dat ai.
Cooling hte demolding:
vulcanization ngut ai hpang, n-gup n-gu hpe katsi hkra la nna, dai hpe shaw la na matu, n-gup magap hpe hpaw dat u.
