Nrog rau kev txhim kho ntawm cov organic silicone kev lag luam thiab kev txhim kho ntawm cov khoom lag luam qib thiab cov txheej txheem thev naus laus zis, cov txheej txheem molding ntawm cov kua silicone khoom tau dhau los ua cov qauv tseem ceeb. Txawm li cas los xij, tus neeg twg uas xav tau cov khoom lag luam zoo thiab siab zoo los xaiv cov kua ua cov hauv paus tsis muaj qhov tsis xws luag, yog li tam sim no cov kua silicone Kev loj hlob ntawm cov txheej txheem yog muaj nuj nqis, thiab nrog cov paub tab ntawm cov txheej txheem, cov ntaub ntawv raw ntawm silica gel. muaj qee yam kev txwv. Lub thev naus laus zis thev naus laus zis ntawm lub zog ua kua silica gel loj?
Tom qab cov kua silicone ua tiav cov khoom siv feem ntau tshaj 50 qib, kev ua cov teeb meem nyuaj ntawm cov khoom lag luam yuav nce ntxiv. Vim tias nws txawv ntawm cov tshuaj molding zoo, cov khoom raw yog nyob rau hauv daim ntawv nrog dej zoo li muab tshuaj txhuam. Yog li no, thaum lub hardness nce ntxiv, kev sib xyaw thiab lub thoob yuav raug teeb meem ntau. Thiab thaum lub hardness nce, lub kua muag kuj yuav poob. Qhov siab dua qhov nyuaj, qhov ntau yog nws tawg thiab tawg.
High-hardness silicone roj hmab cov khoom lag luam tam sim no siv nyob rau hauv ntau yam khoom, thiab kua silica gel tam sim no siv nyob rau hauv qee yam khoom lag luam uas siv ntau hauv peb lub neej. Ob qho kev ua tau zoo thiab lub siab xav tau qhov zoo, tab sis ntau cov khoom siv silicone cov khoom lag luam tsis kam siv cov ntaub ntawv ua kua-siab ua kua silicone, vim tias qhov ua kom lub siab tawv, qhov qeeb ntawm cov khoom siv ua kua tau pub rau hauv cov pwm, kev tsim thiab kev ua yuav cuam tshuam rau qhov ua tau zoo thiab pwm poob, thiab cov neeg pluag thiab kev tsim khoom lag luam yuav raug cuam tshuam.
Txhua leej txhua tus paub tias lub zog-thev naus laus zis thev naus laus zis ntawm cov khoom lag luam silicone muaj tam sim no dhau ntawm 90-qib hardness qhov yuav tsum tau. Raws li thev naus laus zis paub tab, nws zoo li yuav tawg ntawm 100 degrees lossis siab dua qhov nyuaj yav tom ntej. Hauv cov kua silicone ua cov txheej txheem, cov khoom siv siab-lub siab tawv silicone tsis loj. Thaum xyoo ntxov, cov teb chaws txawv teb chaws tau pib kawm qhov hloov ntawm cov qauv tawv-tawv tawv ua kua silicone roj hmab. Txawm li cas los xij, vim muaj teeb meem txuj ci, nws nyuaj rau kev daws qhov teeb meem no. Nws yog qhov tsim nyog yuav tsum ua kom muaj qhov fluidity thiab siab toughness ntawm cov khoom. Xyuas kom meej tias cov ntaub ntawv raw cov khoom siv yog dawb ntawm txhua tus neeg ua hauj lwm sib txuas kom paub meej tias vulcanization molding sijhawm thiab fluidity. Yog li ntawd, cov ntaub ntawv tau txwv rau qhov kub tsawg thiab tau nyuaj rau kev ua tiav.
Tam sim no, cov ntaub ntawv raw ntawm cov kua silicone khoom tau maj mam nce los ntawm thawj 50 degrees rau 60 txog 70 degrees. Tom qab qhov kev poob ntawm cov txheej txheem thev naus laus zis, kev tsim cov kua silicone khoom tau maj mam dhau los. Los ntawm tsuas yog qee lub tebchaws nyob rau yav dhau los tswj hwm lub tshuab thev naus laus zis nyuaj, Nws tau kis rau cov tebchaws thoob ntiaj teb. Nyob rau tam sim no, qhov kev thov rau cov kua silicone cov ntaub ntawv nrog qhov nyuaj thiab siab nyuaj vim yog cov khoom lag luam sib txawv thiab cov kev hloov pauv tau hloov zuj zus. Hnub no 70 degrees yog qhov tam sim no kev txwv ntawm kev lag luam silicone. Silicone raw cov ntaub ntawv yuav maj mam tawg ntawm cov tshuab tsis zoo no.
