Rubber ya Liquid silicone (LSR) ivangwa nigikoresho kibira ifuro (umubiri cyangwa imiti), kandi mugihe cyo gushyushya no gutondekanya ibishishwa muburyo bwo kubumba, umuro wa furo ubyara gaze, bityo ugakora imiterere imwe ya microcellular ifuro.
1. Gutegura ibikoresho bito:
Koresha bibiri - ibice byamazi ya silicone rubber (A&B ibice). Ibikoresho bya reberi yibanze ni pre - byateguwe nuwabitanze. Ibigize A mubisanzwe birimo catalizator, naho B igizwe na agent ihuza. Ukurikije imikorere isabwa mubicuruzwa byanyuma (nkubucucike, ubukana, namabara), birashobora kuba nkenerwa kongeramo ibara ryamabara, kuzuza amashyuza yumuriro (nka alumina), cyangwa ibyuma byaka umuriro nibindi byongewe kumurongo wa rubber. Izi nyongeramusaruro zivanze neza hamwe nigice A cyangwa igice B mbere.
2. Intangiriro yo Kumenyekanisha Intangiriro (Intangiriro ya agent)iyi ni ihuriro rikomeye. Ukurikije ubwoko bwibikoresho byinshi, bigabanijwemo inzira ebyiri tekinike:
Inzira: Kubyara COerc ndengakamere: Liquid CO₂ irashyuha kandi ikotswa igitutu kuri reta idasanzwe binyuze mubikoresho byabigenewe. Gupima no gutera inshinge: Binyuze hejuru ya - pompe yogupima igitutu, umubare munini wa COerc ndengakamere yatewe mumashanyarazi ya A silike ya rubber. Kuvanga static: Ibigize A (bimaze kubamo scCO₂) hamwe na B B bivangwa neza iyo byanyuze muri mix mixer. Hagati aho, scCO₂ ishonga kimwe munganda ya rubber munsi yumuvuduko mwinshi, ikora icyiciro kimwe - icyiciro kimwe kivanze. Inzira yose ikomezwa kumuvuduko mwinshi kugirango CO₂ idahunga imburagihe.
b) Imiti myinshi ifata imiti:Koresha imiti yangirika ya chimique yamashanyarazi, nka azodicarbonamide (AC foaming agent). Inzira: Mbere - vanga ifu ya agent ifuro neza hamwe nigice A cyangwa igice B mubikoresho bikurura. Kugirango ibicuruzwa bitagira inenge - kubuntu, ubusanzwe vacuum irasabwa nyuma yo kuvanga kugirango ikureho umwuka watangijwe mugihe cyo gukurura.
3.Ibirunga no kubira ifuro:
Ifuro ry'umubiri: Nyuma yo guteranya reberi mu cyuho kibumbabumbwe, umuvuduko urekurwa, hamwe na CO₂ ndengakamere ya CO₂ yashonga mu cyuma cya reberi ihinduka vuba vuba, ikora nuclei. Hagati aho, ubushyuhe bwinshi butera ibirunga no kwambuka - guhuza reaction muri reberi ya silicone, gufunga imiterere ya bubble no gukora selile.
Ifuro ya chimique: Ubushyuhe bwinshi bwububiko butera imiti ifata imiti ibora, ikabyara imyuka (nka N₂, CO₂). Muri icyo gihe, reberi ya silicone irarunga, kandi imyuka iba ikubiye mu miyoboro ya reberi, ikora selile.
4. Kwerekana:Nyuma yo kuzunguruka ibibyimba birangiye (mubisanzwe mumasegonda icumi kugeza kuminota mike), fungura ifu hanyuma ukureho ibicuruzwa. Bitewe n'ubukonje buke bwa LSR, ibicuruzwa mubisanzwe ntabwo bifatanye nububiko kandi byoroshye kumeneka.
5. Kohereza - gukiza (volcanisation ya kabiri).
