1. Cheebtsam B ntawm condensation pwm silica gel yog ib tug catalyst, uas yog susceptible mus ya raws hydrolysis, yog li lub hau yuav tsum tau muab kaw tom qab siv.
2. Thaum pawg A thiab B ntawm condensation pwm silica gel sib xyaw, tshuaj lom neeg tshwm sim; Tam sim ntawd, viscosity maj mam nce thiab tsis tuaj yeem nres. Txhawm rau kom tsis txhob pov tseg, nws yuav tsum tau npaj raws li qhov xav tau raws li qhov ntau npaum li cas. Nws yuav tsum tau siv tam sim tom qab kev npaj yam tsis muaj kev ncua.
3. Qhov sib xyaw ua ke ntawm silica gel pawg A thiab B ntawm condensation pwm yog cuam tshuam nrog kev ceev ntawm cov tshuaj tiv thaiv thiab kev ua haujlwm ntawm pwm. Cov tshuaj tiv thaiv B ntau dua, cov tshuaj tiv thaiv sai dua, qhov siab dua lub zog thiab hardness ntawm cov khoom, tab sis qhov qis dua qhov toughness. Yog li ntawd, qhov hnyav hnyav yog yuav tsum tau.
4. Ua ntej kev npaj ntawm silica gel rau condensation pwm, cov khoom A yuav tsum tau nplawm thiab qis tusyees, thiab ces hnyav.
5. Txoj kev pouring yog tsim nyog rau nyem, thiab txoj kev txhuam hniav yog tsim rau kev tsim cov pwm peb sab. Rau casting nyem pwm, thav duab nrog qhov ntev thiab dav ntawm 4-6cm loj dua qhov qub ntev thiab dav yuav tsum tau ua ua ntej. Ciam teb yuav tsum tiaj tus thiab sab hauv yuav tsum du. Thaum nchuav, muab cov thav duab tso rau ntawm lub khob huv si, thiab tom qab ntawd muab cov khoom qub tso rau hauv cov ncej, tawm hauv qhov sib txawv ntawm 2-3cm ntawm txhua sab.
6. Qhov kub ntawm vulcanization ntawm pwm silica gel yog qhov peb feem ntau hu ua chav tsev kub, tab sis qhov kev nyab xeeb ntawm cov cheeb tsam sib txawv txawv, thiab lub ntuj sov hauv chav kuj txawv. Txhawm rau kom vulcanize tag nrho, peb yuav ua kom haum cov tshuaj sulfur raws li qhov kub thiab txias ntawm cov neeg siv khoom hauv ntau cheeb tsam thaum siv.
