Cov khoom lag luam silicone ua kua: Silica gel yog granular, glassy, ntxeem tau silica ua los ntawm hluavtaws sodium silicate. Silica gel yog ib qho nyuaj tshaj li cov gels hauv tsev, xws li gelatin thiab agar. Nws yog cov ntxhia ntuj uas tau ua kom zoo thiab ua tiav rau hauv txhua daim ntawv granular lossis beaded. Cov khoom siv silicone ua los ntawm nws yog dav siv. Tom ntej no, cov khoom lag luam silicone ua kua yuav qhia txog kev siv thiab cuam tshuam rau cov khoom siv silicone:
1. Cov khoom siv silicone ua kua: siv cov khoom siv silicone
1. Cov khoom siv silicone yog cov khoom tseem ceeb rau kev tsim cov tshuab luam ntawv, cov keyboards, hluav taws xob dictionaries, cov chaw taws teeb tswj, cov khoom ua si, cov yuam sij silicone, thiab lwm yam.
2. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob zoo, cov khoom ntim khoom siv rau cov khoom siv hluav taws xob, thiab cov khoom siv kho mob rau cov khoom siv hluav taws xob hauv tsheb.
3. Nws tuaj yeem siv los tsim cov khoom siv hluav taws xob thiab high-point edge pressing pwm.
4. tuaj yeem siv los tsim cov khoom siv hluav taws xob silica gel, kev kho mob silica gel, ua npuas ncauj silica gel, molded silica gel, thiab lwm yam.
5. Siv nyob rau hauv kev sib khi tej yaam num xws li kev kho vaj tse, kev loj kev sib koom tes sealing, thiab choj sealing.
6. tuaj yeem siv rau cov khoom me me, cov khoom lag luam niam thiab menyuam mos, lub raj mis me me, thiab lub raj mis tiv thaiv.
7. Nws tuaj yeem siv rau hauv kev tsim cov khoom siv hauv chav ua noj, cov khoom siv hauv chav ua noj thiab lwm yam khoom siv hauv chav ua noj.
8. Nws tuaj yeem siv rau hauv cov khoom siv kho mob. Nws yog dav siv hauv kev lag luam kho mob vim nws tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom.
2. Cov khoom lag luam silicone ua kua: yam cuam tshuam rau cov khoom siv silicone
1. Viscosity. Viscosity feem ntau yog ncaj qha proportional rau hardness.
2. Hardness. Lub peev xwm ntawm cov khoom siv hauv zos tiv thaiv cov khoom nyuaj uas nias rau hauv nws qhov chaw hu ua hardness. Silicone roj hmab muaj qhov nyuaj ntawm ntug dej hiav txwv ntawm 10 txog 80, muab cov neeg tsim qauv muaj kev ywj pheej xaiv qhov xav tau hardness kom ua tau zoo tshaj plaws ua haujlwm.
3. Lub zog tensile. Lub zog tensile yog lub zog yuav tsum tau rau ib chav tsev ntawm kev ntsuas kom ua rau cov qauv ntawm cov khoom siv roj hmab los tsim kua muag. Lub zog tensile ntawm kua silicone roj hmab yog li ntawm 3.6 txog 11. 0mpa.
4. Lub zog tsim kua muag. Kev tiv thaiv rau lub zog quab yuam ntawm ib qho kev txiav txim siab los tiv thaiv kev nthuav dav ntawm qhov thais. Kub vulcanized khoom silicone roj hmab yuav tsis tsim kua muag txawm nyob rau hauv tsis tshua muaj siab torsional kev nyuaj siab tom qab txiav. Lub zog tsim kua muag ntawm kub vulcanized khoom silicone roj hmab li ntawm 9 txog 55 kn / m. Lub zog tsim kua muag ntawm fluorosilicone roj hmab yog li ntawm 17.5 txog 46.4 kn / m. Lub zog tsim kua muag ntawm cov kua roj hmab silicone yog li ntawm 11.5 txog 52 kn / m. Cov khoom ua kua silicone
5. Elongation. Nws feem ntau yog hais txog "qhov kawg elongation ntawm kev so" lossis qhov feem pua nce ntxiv rau qhov qub ntev ntawm tus qauv tawg. Cov txheej txheem sib txawv thiab xaiv hardener tuaj yeem hloov pauv qhov elongation. Lub elongation ntawm silicone roj hmab yog ze ze rau qhov kub thiab txias.
6. Lub sijhawm ua haujlwm. Lub sijhawm ua haujlwm yog xam los ntawm lub sijhawm tus neeg sawv cev vulcanizing ntxiv rau cov colloid. Qhov tseeb, tsis muaj kev txwv tag nrho ntawm lub sijhawm ua haujlwm no thiab lub sijhawm vulcanization tom ntej. Ntau lub sij hawm-txuag cov txheej txheem ntawm cov khoom lag luam yog, qhov zoo dua rau cov khoom tiav.
7. Lub sijhawm kho. Qee qhov chaw yuav hais tias qhov no yog lub sijhawm vulcanization. Hauv lwm lo lus, tom qab lub sijhawm ntev, cov tshuaj tiv thaiv vulcanization ntawm silica gel yog qhov pib dhau. Qhov no tseem ceeb kawg ntawm cov khoom uas tau siv, tab sis qhov tseeb, tseem muaj ib feem me me ntawm kev kho cov tshuaj tiv thaiv uas tseem tsis tau ua tiav. Yog li ntawd, cov khoom ua los ntawm silicone roj hmab, xws li silicone pwm, feem ntau yuav tsum tau muab tso rau hauv ib lub sij hawm.
